Vishay Intertechnology (NYSE: VSH) has introduced the TSOP15300 series infrared (IR) receiver modules for remote control applications. The devices feature a wide 30 kHz to 68 kHz modulation frequency range, enabling reception and demodulation of all major remote control codes with a single component, helping reduce component counts, system cost, and board space.
Targeted at consumer electronics including TVs, audio systems, gaming consoles, soundbars, STBs, and projectors, the receivers offer immunity to ripple noise and interference from CFL and LCD IR emissions and onboard Wi-Fi RF signals. In a 4-pin Heimdall package, they integrate a photodetector, preamplifier, and IR filter, support supply voltages from 2.0 V to 5.5 V, typical current of 0.35 mA, and transmission distances up to 18 m with a 50 mA emitter. The RoHS-compliant, halogen-free, Vishay Green devices are available in samples and volume with six-week lead times.

Analysis
DIOD rose 5.396515876054764% in the momentum scan, with seven peers moving up. Against that backdrop, the receiver launch adds product breadth; the active S-3ASR shelf and moderate short positioning remain relevant risks to monitor.

5 terms
modulation frequencytechnical
"Featuring a wide modulation frequency acceptance from 30 kHz to 68 kHz"
The rate at which a carrier signal is varied to carry information, measured in cycles per second (hertz); for example, how fast a radio wave’s amplitude, frequency, or phase is changed to encode data. Think of it like the speed of a blinking flashlight used to send Morse code: faster or different patterns change how much and how reliably you can send. Investors care because modulation frequency affects product performance, compatibility with standards, spectrum use, and regulatory approval, all of which influence market potential.
demodulated output signaltechnical
"their demodulated output signal can be directly connected to a microprocessor"
The demodulated output signal is the recovered information (audio, digital data, or baseband waveform) produced when a receiver extracts the original message from a modulated carrier wave. Think of it as the decoded sound from a radio station after the carrier is stripped away. For investors, the quality and reliability of that output affect product performance, user experience, regulatory compliance, and competitive positioning in communications or sensor markets.
photodetectortechnical
"each receiver integrates a photodetector, preamplifier circuit, and IR filter"
A photodetector is an electronic component that senses light and converts it into an electrical signal, like a tiny eye that turns photons into voltage or current. It matters to investors because these components are essential in products and systems—such as optical communications, sensors, cameras, LiDAR and medical devices—so demand, supply constraints, or cost improvements in photodetectors can affect revenue, margins, and technological competitiveness across multiple industries.
preamplifier circuittechnical
"integrates a photodetector, preamplifier circuit, and IR filter"
An electronic stage that boosts very weak electrical signals from sensors, microphones, or antennas to a level suitable for further processing without adding excessive noise. Think of it as a sensitive microphone that quietly raises a whisper to a normal conversation volume so later parts of a device can work reliably. Investors care because the quality, cost, power use, and reliability of preamplifier circuits affect product performance, manufacturing margins, and regulatory testing outcomes.
rohs-compliantregulatory
"They are RoHS-compliant, halogen-free, and Vishay Green."
RoHS-compliant means a product meets rules that limit or ban certain hazardous chemicals in electrical and electronic equipment, ensuring the item does not contain those restricted substances above set limits. For investors this matters because compliance affects a company's ability to sell in regulated markets, avoid fines and recalls, and manage production costs and supply-chain risks—similar to a food product following a recipe that omits banned ingredients to stay sellable and safe.
Saving Space and Reducing Component Counts to Simplify Universal Remote Control Designs, Devices Feature a Wide 30 kHz to 68 kHz Modulation Frequency Range
MALVERN, Pa., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of infrared (IR) receiver modules for IR remote control applications.Featuring a wide modulation frequency acceptance from 30 kHz to 68 kHz, devices in the Vishay Semiconductors TSOP15300 series are designed to receive and demodulate all major remote control codes on the market, enabling a single-component universal remote control solution.
Standard IR receivers are typically tuned to one center frequency, limiting compatibility and requiring multiple devices to cover different code sets. With their wide modulation frequency range, the receivers released today overcome this limitation, reducing component counts to lower system costs and save board space.
Designed for consumer electronics such as televisions, audio systems, gaming consoles, soundbars, set-top boxes (STB), video projectors, and more, TSOP15300 series receivers provide immunity against ripple noise and interference from common sources like IR emissions in CFL lamps and LCD televisions, and RF emissions from onboard Wi-Fi antennas. When paired with a 50 mA emitter, the devices offer reliable transmission distances of up to 18 m.
To simplify designs, each receiver integrates a photodetector, preamplifier circuit, and IR filter within a 4-pin Heimdall package. For decoding, their demodulated output signal can be directly connected to a microprocessor. Optimized for short burst codes, TSOP15300 series devices operate over a wide supply voltage range from 2.0 V to 5.5 V, draw a typical supply current of 0.35 mA, and feature a maximum irradiance of 0.2 mW/m² at 45 kHz. They are RoHS-compliant, halogen-free, and Vishay Green.
Samples and production quantities of the new IR receiver modules are available now, with lead times of six weeks.
