Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA30CA TVS Diode from VISHAY**  

The **P4SMA30CA** is a surface-mount **Transient Voltage Suppression (TVS) diode** designed to protect sensitive electronic circuits from voltage transients, electrostatic discharge (ESD), and other surge events. Manufactured by **VISHAY**, this bidirectional diode offers robust clamping performance with a **standoff voltage of 30V** and a **peak pulse power rating of 400W (10/1000µs)**.  

Housed in a compact **SMA (DO-214AC) package**, the P4SMA30CA is ideal for applications where board space is limited. Its low clamping voltage and fast response time make it suitable for safeguarding **power supplies, communication ports, automotive systems, and industrial electronics** against transient overvoltage conditions.  

Key features include a **high surge capability**, low leakage current, and compliance with **AEC-Q101** standards for automotive applications. The bidirectional nature of the diode allows it to suppress both positive and negative voltage spikes, enhancing its versatility in circuit protection.  

Engineers favor the P4SMA30CA for its reliability in harsh environments, ensuring long-term stability in systems exposed to electrical noise or transient disturbances. Its combination of performance and compact design makes it a preferred choice for modern electronic designs requiring robust overvoltage protection.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ30CA --: Same SMA package bidirectional 30V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ30CA --: Bidirectional 30V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1SMA30CAT3G --: SMA-packaged bidirectional 30V TVS diode from a major supplier, electrically similar and suitable as a drop-in replacement.
  • SMAJ30CA --: Same SMA package, 400W bidirectional TVS with 30V standoff voltage; widely available and electrically equivalent.
  • SMBJ30CA --: Bidirectional 30V TVS in SMB package with higher 600W surge rating; drop-in for most designs with adequate board space.
  • 1SMA30CAT3G --: SMA-packaged bidirectional 30V TVS with comparable 400W rating, suitable as a direct functional replacement.
