Description and Introduction

ARK Electronics - Surface Mount Transient Voltage Suppressors Peak Pulse Power 400W Breakdown Voltage 6.8 to 550V **Introduction to the P4SMA350A TVS Diode from VISHAY**  

The P4SMA350A is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transients. Manufactured by VISHAY, this component offers robust surge protection with a standoff voltage of 350V and a peak pulse power dissipation of 400W (10/1000μs waveform).  

Featuring a low clamping voltage, the P4SMA350A ensures effective suppression of transient overvoltages, safeguarding downstream components from damage. Its fast response time makes it suitable for applications exposed to electrostatic discharge (ESD), lightning-induced surges, and other high-energy transients.  

The diode is housed in a compact SMA (DO-214AC) package, making it ideal for space-constrained designs in industries such as telecommunications, industrial automation, and power supplies. With a wide operating temperature range and high reliability, the P4SMA350A is engineered for demanding environments.  

Key features include a unidirectional configuration, high surge capability, and compliance with industry standards for surge protection. Engineers can rely on this TVS diode for consistent performance in mitigating transient threats while maintaining system integrity.  

For detailed specifications, refer to the manufacturer’s datasheet to ensure proper integration into circuit designs.

Application Scenarios & Design Considerations

Alternative Part Number

  • SMAJ350A --: Same SMA package unidirectional TVS diode with 350V standoff voltage and similar clamping performance, widely available and pin-compatible.
  • SMBJ350A --: Unidirectional 350V TVS diode with comparable surge rating; SMB package is slightly larger but electrically equivalent and easy to substitute.
  • 1.5SMC350A --: Higher power 1500W 350V unidirectional TVS in SMC package, offers equal or better surge protection and can replace the original with margin.
  • SMAJ350A --: Same SMA package unidirectional TVS with 350V standoff and similar clamping, widely available and pin-compatible.
  • SMBJ350A --: Unidirectional 350V TVS with comparable surge rating; SMB package is slightly larger but electrically suitable for most designs.
  • 1.5SMC350A --: 350V unidirectional TVS in SMC package offering higher peak pulse power, usable as a robust drop-in substitute where board space allows.
