Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA11CA TVS Diode from VISHAY**  

The P4SMA11CA is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient events. Manufactured by VISHAY, this component offers robust clamping performance, making it suitable for applications in power supplies, communication systems, and industrial electronics where overvoltage protection is critical.  

With a standoff voltage of 11V and a peak pulse power rating of 400W (10/1000μs waveform), the P4SMA11CA efficiently diverts excess energy away from protected circuits. Its low clamping voltage ensures minimal stress on downstream components, enhancing system reliability. The diode features a fast response time, reacting almost instantaneously to transient threats such as electrostatic discharge (ESD) and lightning-induced surges.  

Encased in a compact SMA (DO-214AC) package, the P4SMA11CA is ideal for space-constrained designs while maintaining high thermal efficiency. Its bidirectional configuration simplifies circuit integration by providing protection against both positive and negative voltage transients.  

Engineers frequently select the P4SMA11CA for its balance of performance, durability, and cost-effectiveness, making it a trusted solution for safeguarding modern electronic systems against transient disturbances.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ11CA --: Same SMA package bidirectional TVS diode with 11V standoff voltage and comparable clamping performance; widely available and pin-compatible.
  • SMBJ11CA --: Bidirectional 11V TVS in SMB package offering higher surge rating; can replace P4SMA11CA where slightly larger footprint is acceptable.
  • 1SMA11CAT3G --: SMA-packaged bidirectional 11V TVS diode with similar electrical characteristics and drop-in compatibility for most protection circuits.
  • SMAJ11CA --: Same SMA package bidirectional TVS diode with 11V standoff voltage and comparable clamping performance; widely available and a direct functional drop-in.
  • SMBJ11CA --: Bidirectional 11V TVS in SMB package offering similar or higher surge rating; slightly larger footprint but electrically compatible for most designs.
  • P6SMB11CA --: 600W bidirectional TVS with 11V standoff in SMB package; higher power handling provides margin and is a common cross-reference for SMA 400W parts.
