Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA9.1CA TVS Diode from VISHAY**  

The **P4SMA9.1CA** is a high-performance **Transient Voltage Suppression (TVS) diode** designed to protect sensitive electronic circuits from voltage spikes and transient events. Manufactured by **VISHAY**, this bidirectional diode offers robust **ESD (electrostatic discharge) and surge protection**, making it ideal for applications in power supplies, communication systems, and industrial electronics.  

With a **standoff voltage of 9.1V** and a **peak pulse power rating of 400W**, the P4SMA9.1CA efficiently clamps transient voltages to safe levels, preventing damage to downstream components. Its **low clamping voltage** and **fast response time** ensure reliable performance against sudden overvoltage conditions.  

Housed in a **SMA (DO-214AC) package**, the diode is compact yet durable, suitable for space-constrained designs. It meets industry standards for reliability, including **AEC-Q101 qualification** for automotive applications, ensuring stability in harsh environments.  

Key features include:  
- **Bidirectional protection**  
- **Low leakage current**  
- **High surge capability**  
- **RoHS compliance**  

The P4SMA9.1CA is a dependable solution for safeguarding circuits against transient threats, combining efficiency with robust construction for long-term reliability.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ9.1CA --: Same SMA package, 400W bidirectional TVS with 9.1V standoff voltage; direct functional equivalent from a different series.
  • SMBJ9.1CA --: Bidirectional 600W TVS in SMB package with matching 9.1V standoff; higher surge rating and widely available alternative.
  • 1SMA9.1CAT3G --: 400W bidirectional TVS in SMA package with 9.1V standoff voltage, suitable drop-in replacement from a different manufacturer series.
  • SMAJ9.1CA --: Same SMA package bidirectional 9.1V TVS diode with comparable clamping voltage and power rating, widely available from a major manufacturer.
  • SMBJ9.1CA --: Bidirectional 9.1V TVS in SMB package offering higher surge power margin; suitable if board space allows the slightly larger footprint.
  • P6SMB9.1CA --: Bidirectional 9.1V TVS with 600W peak pulse rating in SMB package, providing extra surge protection headroom as a robust substitute.
