Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA82CA TVS Diode from GS**  

The P4SMA82CA 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 component offers robust clamping performance, making it suitable for applications in power supplies, communication systems, and automotive electronics.  

With a standoff voltage of 82V and a peak pulse power rating of 400W, the P4SMA82CA efficiently diverts transient surges away from critical components. Its fast response time ensures minimal voltage overshoot, safeguarding downstream circuitry. The diode operates within a wide temperature range, ensuring reliability in harsh environments.  

Encased in a compact SMA (DO-214AC) package, the P4SMA82CA is ideal for space-constrained designs while maintaining high surge-handling capabilities. It complies with industry standards, making it a dependable choice for engineers seeking effective overvoltage protection.  

Key features include low leakage current, high surge durability, and bidirectional operation, which simplifies circuit integration. Whether used in industrial controls, consumer electronics, or telecommunications, the P4SMA82CA provides a cost-effective solution for transient suppression.  

For detailed specifications, always refer to the manufacturer’s datasheet to ensure proper application and performance alignment with system requirements.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ82CA --: Same SMA package, 400W bidirectional TVS with 82V standoff voltage, direct functional equivalent.
  • SMBJ82CA --: Bidirectional 82V TVS in SMB package with higher 600W surge rating, suitable drop-in upgrade for most layouts.
  • 1SMB82CAT3G --: Bidirectional 82V TVS in SMB package, 600W peak pulse power, well-established alternative with similar clamping characteristics.
  • SMAJ82CA --: Same SMA package bidirectional 82V TVS diode with comparable clamping voltage and power rating, widely available from a major supplier.
  • SMBJ82CA --: Bidirectional 82V TVS in SMB package offers higher surge capability and is a common drop-in upgrade when board space allows.
  • P6SMB82CA --: 600W bidirectional 82V TVS in SMB package provides similar protection with greater peak pulse power margin.
