概述
Description
P6SMB36A is a 600 W peak pulse power TVS diode in an SMB package. The “A” suffix indicates a unidirectional device with a nominal stand-off voltage around 36 V.
What it does:
- Protects DC power lines and signal lines from transient overvoltage (ESD, load dumps, inductive spikes, switching transients).
How to use:
- Placed across the line to ground (cathode to the protected line, anode to ground).
Key specs you’ll care about:
- Vwm (stand-off voltage): ~36 V
- Vbr and Vclamp: depend on pulse current and are specified in the datasheet
- IPP: 600 W peak pulse power
- Temperature range and package footprint per datasheet
Selection tips:
- Choose a part with Vwm above your normal operating voltage but below the circuit’s stress, and ensure adequate clamping for fault conditions.
- Place close to the entry point of the protected circuit.
Applications:
- Automotive, industrial 24–28 V rails, telecom, power-supply protection, and other transient-prone electronics.
For exact values (Vbr, Vclamp, leakage, footprint), consult the manufacturer’s datasheet.
