P6SMB200AT3G

P6SMB200AT3G is a high‑power transient‑voltage-suppressor (TVS) diode in an SMB (DO-214AB) package. It’s used to protect electrical and electronic circuits from voltage spikes and ESD on power and data lines. The “200A” indicates a nominal stand‑off voltage around 200 V (unidirectional variant, typically denoted by the “A” in the code). The device is part of the P6SMB family and is rated for high peak pulse power (about 600 W, 10/1000 µs). The “T3G” suffix refers to packaging/ RoHS/tape‑and‑reel options. Applications include automotive, telecom, power supplies, and other systems needing surge suppression. For exact VR, breakdown, clamping voltages, leakage, and pinout, consult the manufacturer datasheet (e.g., Vishay) for P6SMB200AT3G.

Here are the typical features for P6SMB200AT3G (a 600 W TVS diode in SMB package):
- 600 W peak pulse power capability (10/1000 µs)
- Working reverse standoff voltage VRWM = 200 V (unidirectional version)
- Fast transient protection for high-energy lines and interfaces
- Surface-mount SMB (DO-214AB) package for compact PCB mounting
- Wide operating temp range: -55°C to +125°C
- RoHS-compliant and lead-free (T3G/taped packaging)
