5.0V–90V Working Voltage with Fast Clamping in a Low‑Profile SOD‑323HE‑B Package
MCC introduces the SMHE series 150W TVS diodes, designed to deliver reliable transient voltage protection for sensitive electronics in automotive, industrial, and automation applications. With a wide working voltage range from 5.0V to 90V and a compact, low‑profile SOD‑323HE‑B package, the SMHE series supports high‑density surface‑mount designs while maintaining strong protection performance.
Rated for up to 150W peak pulse power (10/1000 µs waveform), the SMHE series offers fast response and excellent clamping capability to guard against induced transients and automotive load dump events. AEC‑Q101 qualification, combined with RoHS‑compliant and halogen‑free construction, ensures long‑term reliability, environmental compliance, and reduced design complexity across power, data, and signal line protection needs.

Understanding TVS Diode Operation and Selection
TVS diodes are protection devices designed to clamp high-energy voltage transients before they can damage sensitive circuitry. Proper device selection requires matching working voltage, breakdown voltage, clamping voltage, and peak pulse power to the expected surge conditions.
Understanding how parameters such as VRWM, VBR, and VC interact is essential to ensure effective protection without overstressing downstream components.
To review TVS operating principles, key parameter definitions, and practical selection methodology, explore our technical guide: Understanding TVS Diodes: A Comprehensive Guide.
