Description and Introduction

ARK Electronics - Surface Mount Transient Voltage Suppressors Peak Pulse Power 400W Breakdown Voltage 6.8 to 550V The **P4SMA400A** from **VISHAY** is a high-performance **surface-mount transient voltage suppressor (TVS) diode** designed to protect sensitive electronic circuits from voltage transients and electrostatic discharge (ESD). With a **standoff voltage of 400V** and a **peak pulse power dissipation of 400W**, this component is well-suited for applications requiring robust surge protection in a compact form factor.  

Featuring a **low clamping voltage** and **fast response time**, the P4SMA400A effectively diverts excessive transient energy away from critical components, ensuring reliable operation in harsh electrical environments. Its **unidirectional configuration** makes it ideal for safeguarding DC circuits, while its **SMA package** allows for efficient PCB integration in space-constrained designs.  

Common applications include **power supplies, industrial controls, telecommunications equipment, and automotive electronics**, where transient overvoltage events pose a risk to system integrity. The P4SMA400A meets industry standards for reliability and performance, making it a trusted choice for engineers seeking durable overvoltage protection.  

With its combination of high surge capability and compact design, the P4SMA400A exemplifies VISHAY's commitment to delivering high-quality TVS solutions for modern electronic systems.

Application Scenarios & Design Considerations

Alternative Part Number

  • SMAJ400A --: Same SMA package unidirectional 400V TVS diode with comparable clamping voltage and power rating, widely available and a direct functional substitute.
  • SMBJ400A --: 400V unidirectional TVS in SMB package offering higher surge power margin; electrically compatible and can replace P4SMA400A where board space allows.
  • 1.5SMC400A --: 400V unidirectional TVS diode with similar standoff voltage and robust surge capability, suitable as an alternative protection device.
  • SMAJ400A --: Same SMA package unidirectional TVS with 400V standoff voltage and similar clamping performance, widely available and directly drop-in compatible.
  • SMBJ400A --: 400V unidirectional TVS with comparable surge rating; SMB package is slightly larger but electrically equivalent and can be used where board space allows.
  • 1.5SMC400A --: Higher power 1500W 400V unidirectional TVS offering greater surge margin; suitable as a robust replacement when extra transient capability is acceptable.
