Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA91CA TVS Diode from GS**  

The P4SMA91CA is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD). Manufactured by GS, this bidirectional diode offers robust clamping performance, making it suitable for applications in power supplies, communication systems, and industrial electronics.  

With a standoff voltage of 91V and a peak pulse power rating of 400W (10/1000μs waveform), the P4SMA91CA provides reliable overvoltage protection. Its low clamping voltage ensures minimal stress on downstream components, enhancing system reliability. The device complies with industry-standard DO-214AC (SMA) packaging, facilitating easy integration into PCB designs.  

Key features include fast response time, high surge capability, and compliance with RoHS standards, making it an environmentally friendly choice. The P4SMA91CA is ideal for safeguarding circuits in automotive, telecommunications, and consumer electronics where transient suppression is critical.  

Engineers value this component for its balance of performance and compact form factor, ensuring efficient protection without compromising board space. Whether used in surge protection modules or as part of a broader ESD mitigation strategy, the P4SMA91CA delivers dependable performance in demanding environments.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ91CA --: Same SMA package bidirectional 91V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ91CA --: Bidirectional 91V TVS in SMB package offering higher surge power margin; can replace with minor board space adjustment.
  • 1.5SMC91CA --: Bidirectional 91V TVS with 1500W peak pulse rating in SMC package, suitable when higher surge capability is acceptable.
  • SMAJ91CA --: Same SMA package, 400W bidirectional TVS with 91V standoff voltage; direct functional equivalent from a different series.
  • SMBJ91CA --: Bidirectional 91V TVS in SMB package with higher 600W surge rating; suitable upgrade if board space allows.
  • 1SMA91CAT3G --: SMA-packaged 400W bidirectional TVS with 91V standoff, matching electrical ratings from an alternate vendor.
