Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors # Introduction to the P4SMA7.5CA TVS Diode from VISHAY  

The **P4SMA7.5CA** is a high-performance **transient voltage suppressor (TVS) diode** designed by **VISHAY** to protect sensitive electronic circuits from voltage spikes and transient events. This bidirectional diode is part of the **P4SMA series**, offering robust surge protection in a compact **DO-214AC (SMA) package**, making it suitable for space-constrained applications.  

With a **standoff voltage of 7.5V** and a **breakdown voltage range of 8.33V to 9.23V**, the P4SMA7.5CA effectively clamps transient voltages to safe levels. It provides a **peak pulse power dissipation of 400W (10/1000μs waveform)**, ensuring reliable protection against electrostatic discharge (ESD), lightning-induced surges, and other transient threats.  

Key features include **low clamping voltage**, **fast response time**, and **high surge capability**, making it ideal for use in **consumer electronics, industrial systems, automotive circuits, and telecommunications equipment**. Its bidirectional design simplifies circuit implementation by eliminating polarity concerns.  

Engineers favor the P4SMA7.5CA for its **high reliability**, **consistent performance**, and compliance with industry standards, ensuring robust protection in demanding environments. Whether safeguarding data lines, power supplies, or communication interfaces, this TVS diode delivers dependable overvoltage protection in a compact form factor.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ7.5CA --: Same SMA package bidirectional 7.5V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ7.5CA --: Bidirectional 7.5V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1SMA7.5CAT3G --: SMA-packaged bidirectional 7.5V TVS diode with equivalent standoff voltage and similar clamping characteristics, suitable drop-in replacement.
  • SMAJ7.5CA --: Same SMA package bidirectional 7.5V TVS diode with comparable clamping voltage and power rating, widely available and a direct functional substitute.
  • SMBJ7.5CA --: Bidirectional 7.5V TVS in SMB package offering higher surge power margin; electrically compatible and can replace the part where board space allows.
  • 1.5SMC7.5CA --: Bidirectional 7.5V TVS diode with similar standoff voltage and robust surge capability, suitable as an alternative when a slightly larger package is acceptable.
