SM8S24AHE3_A/I VISHAY Circuit Protection

The SM8S24AHE3_A/I from Vishay is an automotive-grade 6600W PAR® TVS diode, AEC-Q101 qualified for high-reliability transient voltage suppression in harsh environments. For selection, it features a 24V reverse standoff voltage, a 26.7V minimum breakdown voltage, and a 38.9V maximum clamping voltage, safely protecting 24V power rails. The diode handles a 170A peak pulse current under the 10/1000µs waveform and delivers 6600W peak pulse power, ensuring robust suppression of load dump surges per ISO 7637-2. Key specifications include ultra-low 10µA reverse leakage, 700A maximum forward surge current, and a wide -55°C to +175°C operating junction temperature for under‑hood automotive environments. The surface‑mount DO‑218AB package enables compact PCB layouts with efficient automated assembly. In application, it is purpose‑built to shield sensitive electronic control units, sensors, and infotainment systems in 24V automotive and commercial vehicles against lightning strikes, inductive load switching, and severe load dump transients per ISO 16750‑2.
