Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA220CA TVS Diode from VISHAY**  

The P4SMA220CA is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient events. Manufactured by VISHAY, this bidirectional diode offers robust clamping performance, making it suitable for applications where overvoltage protection is critical.  

With a standoff voltage of 220V and a peak pulse power rating of 400W, the P4SMA220CA effectively suppresses fast-rising transients, including those caused by electrostatic discharge (ESD), lightning surges, and inductive load switching. Its low clamping voltage ensures minimal stress on protected components, enhancing system reliability.  

The compact SMA (DO-214AC) package allows for easy integration into space-constrained designs, making it ideal for use in telecommunications, industrial controls, automotive systems, and power supply circuits. The device meets industry standards for performance and durability, ensuring consistent operation under harsh conditions.  

Key features include a fast response time, high surge capability, and bidirectional polarity, which simplifies circuit design by eliminating the need for orientation considerations. Engineers seeking a dependable solution for transient voltage protection will find the P4SMA220CA a practical choice for safeguarding critical electronics.

Alternative Part Number

  • SMAJ220CA --: Same SMA package bidirectional 220V TVS diode with comparable clamping voltage and power rating, direct functional drop-in.
  • SMBJ220CA --: Bidirectional 220V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1SMA220CA --: SMA-packaged bidirectional 220V TVS with similar standoff and clamping characteristics, suitable as a cost-effective substitute.
  • SMAJ220CA --: Same SMA package bidirectional 220V TVS diode with comparable clamping voltage and power rating, widely available from a major supplier.
  • SMBJ220CA --: Bidirectional 220V TVS in SMB package offering higher surge power margin; suitable if board space allows the slightly larger footprint.
  • 1.5SMC220CA --: 1500W bidirectional 220V TVS in SMC package providing extra surge capability as a robust drop-in style replacement.
