概述
Description
SMCJ170A is a high‑power transient-voltage-suppressor (TVS) diode in the SMC (DO‑214AB) package. It protects high‑voltage DC rails from fast transients by clamping voltage spikes to safe levels. The 170V rating indicates a working (stand‑off) voltage near 170 V, and the “A” suffix denotes the unidirectional variant. It offers about 600 W peak pulse power (10/1000 µs) with clamped voltage that depends on surge current. Typical applications include telecom and industrial power supplies, HV DC rails, and other high‑voltage electronics needing robust surge protection. For exact specs (V_RWM, V_BR, V_CL, I_pp, packaging, etc.), consult the manufacturer’s datasheet.
