Overview

The 3SMC75A TR13 PBFREE is a unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from high-voltage transients. Housed in a surface-mount SMC (DO-214AB) package, it is capable of dissipating 3000W of peak pulse power.

Why Choose This Part

This device offers a high peak pulse power rating of 3000W and a fast response time characteristic of Zener-type TVS diodes. With a breakdown voltage starting at 83.3V and a maximum clamping voltage of 121V, it is well-suited for systems operating with significant voltage margins.

Applications

Industrial DC Power Rails
Provides overvoltage clamping for high-voltage DC supply lines in automation and control equipment.
Telecommunications Infrastructure
Protects sensitive line cards and switching hardware from atmospheric lightning induced transients.
Power Supply Input Protection
Acts as a primary clamp for power converters to prevent damage from inductive load switching or mains fluctuations.

Getting Started

Ensure the diode's cathode is oriented toward the positive rail for unidirectional protection. When designing the PCB layout, place the SMC footprint as close to the entry point of the transient source as possible and use wide traces to handle the 24.8A peak pulse current.
