Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA350CA TVS Diode from VISHAY**  

The P4SMA350CA is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD). Manufactured by VISHAY, this bidirectional diode offers robust clamping performance with a standoff voltage of 350V, making it suitable for applications in industrial, automotive, and telecommunications systems where overvoltage events are a concern.  

Featuring a low clamping voltage and fast response time, the P4SMA350CA effectively diverts transient currents away from critical components, ensuring reliable operation in harsh environments. Its compact SMA (DO-214AC) package allows for efficient PCB space utilization while maintaining high power dissipation capabilities.  

Key specifications include a peak pulse power rating of 400W (10/1000μs) and an operating temperature range of -55°C to +150°C, ensuring performance stability under extreme conditions. The device complies with industry standards such as AEC-Q101 for automotive applications, reinforcing its durability and suitability for high-reliability systems.  

Ideal for surge protection in power supplies, data lines, and communication interfaces, the P4SMA350CA provides engineers with a dependable solution for safeguarding electronics against transient threats. Its combination of high surge capability and compact form factor makes it a versatile choice for modern circuit protection needs.

Alternative Part Number

  • SMAJ350CA --: Same SMA package bidirectional 350V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ350CA --: Bidirectional 350V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1.5SMC350CA --: 1500W bidirectional 350V TVS with similar electrical characteristics, suitable as a higher-power drop-in substitute where layout permits.
  • SMAJ350CA --: Same SMA package bidirectional 350V TVS diode with comparable clamping and power rating, widely available and pin-compatible.
  • SMBJ350CA --: Bidirectional 350V TVS in SMB package offering higher surge capability; usable if board space allows the slightly larger footprint.
  • 1.5SMC350CA --: 350V bidirectional TVS with 1500W peak pulse rating in SMC package, suitable as a higher-power drop-in style replacement.
