1N5908 ST Diode

The 1N5908 from ST is a 1500 W unidirectional TRANSIL TVS diode purpose‑built to protect 5 V logic (TTL/CMOS) circuits and sensitive ICs. For selection, it features a 5 V reverse standoff, 6 V minimum breakdown, and a low 8.5 V clamping voltage at 120 A peak pulse current (10/1000 µs), ensuring fast response and low clamping factor. The 1500 W peak pulse power, together with -55 °C to +175 °C junction range, meets IEC 61000‑4‑2, IEC 61000‑4‑5, and MIL‑STD‑883 standards, while its DO‑201 through‑hole package simplifies layout. In application it provides board‑level protection for I/O ports, power rails, and microcontroller inputs in industrial automation, PLCs, telecom, consumer electronics, and automotive body ECUs where reliable surge suppression is critical.
