Key Terms

common mode transient immunity, comparative tracking index, faraday shield, optocoupler

4 terms

common mode transient immunity technical

"minimum guaranteed common mode transient immunity (CMTI) of 40 kV/µS"

The ability of an electronic device or system to withstand brief, sudden voltage or electrical disturbances that appear equally on multiple conductors relative to ground. Think of it like a car’s suspension absorbing a pothole that hits both wheels at once; strong immunity means fewer malfunctions, lower recall and repair costs, and smoother regulatory approval—factors that directly affect a product’s reliability, marketability, and a company’s financial risk.

comparative tracking index technical

"Combining a comparative tracking index (CTI) of 400 with"

A comparative tracking index is a benchmark that aggregates the returns of a chosen market, sector, or group of peers so investors can directly compare how a specific fund or portfolio performs against that reference. Like comparing a car’s fuel efficiency on a highway versus in the city, it makes it easy to see whether an investment is keeping pace, consistently underperforming, or outperforming, which helps evaluate manager skill, risk and whether fees are justified.

faraday shield technical

"while a Faraday shield on the detector chip allows the device"

A Faraday shield is a conductive barrier that blocks external electric fields and prevents electrical interference from reaching sensitive components, like a metal cage that keeps static and radio waves out. For investors, it matters because devices, sensors, and medical equipment that include effective Faraday shielding can perform more reliably, meet regulatory electromagnetic-compatibility standards, and reduce failure or liability risks tied to interference.

optocoupler technical

"introduced an automotive 1 MBd high speed optocoupler in a new SOP-5"

An optocoupler is a small electronic component that transmits a signal between two separate circuits using light, so the circuits are electrically isolated from each other. For investors, it matters because this isolation improves safety and reliability in products like power supplies, industrial controllers, and medical devices; demand and pricing for optocouplers can affect manufacturers’ costs, product certifications, and exposure to supply-chain or regulatory risks.

AEC-Q102 Qualified Device Offers Industry-Best Minimum CMTI of 40 kV/µS and Maximum Repetitive Peak Isolation Voltage of 707 V_peak

MALVERN, Pa., July 09, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced an automotive 1 MBd high speed optocoupler in a new SOP-5 package with a narrow width of 3.6 mm. Combining a comparative tracking index (CTI) of 400 with industry-leading minimum guaranteed common mode transient immunity (CMTI) of 40 kV/µS, the Vishay Semiconductors VOMHA43A is designed to deliver improved signal transmission quality and save space in applications requiring isolation voltages (V_IORM) up to 707 V_peak.

The AEC-Q102 qualified device released today is optimized for isolated data communication, fast signal switching, ground signal isolation, and logic voltage level shifting in automotive, industrial, home and building control, and telecom applications. In electric (EV), hybrid electric (HEV), and low speed electric (LSEV) vehicles, the optocoupler provides communication bus isolation for CAN, LIN, I²C, and SPI interfaces, as well as isolated drive circuit applications such as intelligent power module (IPM) drivers.

While previous SOP-5 packages offered a width of 4.4 mm, the narrower SOP-5 of the VOMHA43A requires less PCB space, while supporting stackable designs. The device’s minimum CMTI — which is more than double that of the closest competing device — provides enhanced robustness against electrical spikes and RF and EMI issues. And while competing devices offer maximum repetitive peak isolation voltages of 567 V_peak, the optocoupler’s isolation voltage performance of 707 V_peak meets the requirements of 400 V battery systems.

The VOMHA43A consists of a GaAlAs infrared emitting diode, optically coupled with an integrated photodetector and a high speed transistor. The photodetector is junction-isolated from the transistor to reduce miller capacitance effects. The optocoupler features an open collector output function that allows designers to adjust load conditions when interfacing with different logic systems, while a Faraday shield on the detector chip allows the device to reject and minimize high input to output common mode transient voltages.

The RoHS-compliant and halogen-free optocoupler operates over a temperature range of -40 °C to +125 °C and is pin to pin compatible with leading competing parts to provide a direct replacement and eliminate the need for electrical and mechanical redesigns.

Samples and production quantities of the VOMHA43A are available now, with lead times of six weeks.
