Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors The **P4SMA15CA** from **GS** is a high-performance **15V unidirectional TVS diode** designed to protect sensitive electronic circuits from transient voltage spikes. This component is part of the **P4SMA series**, which is widely used in applications requiring robust **electrostatic discharge (ESD) and surge protection**.  

Featuring a **low clamping voltage** and **fast response time**, the P4SMA15CA effectively diverts excessive voltage away from critical components, ensuring system reliability. Its **15V standoff voltage** makes it suitable for safeguarding low-voltage circuits in **telecommunications, industrial controls, and consumer electronics**.  

The **axial-leaded package** allows for easy PCB mounting, while its **high surge capability** (up to **600W peak pulse power**) ensures durability in demanding environments. With **UL recognition** and compliance with **RoHS standards**, the P4SMA15CA meets stringent industry requirements for safety and environmental responsibility.  

Engineers often choose this TVS diode for its **balance of performance and cost-effectiveness**, making it a practical solution for transient voltage suppression in modern electronic designs. Whether used in **power supplies, data lines, or signal interfaces**, the P4SMA15CA provides reliable overvoltage protection with minimal impact on circuit performance.  

For detailed specifications, always refer to the **official datasheet** to ensure proper integration into your design.

Application Scenarios & Design Considerations

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors

Alternative Part Number

  • SMAJ15CA --: Same SMA package bidirectional 15V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ15CA --: Bidirectional 15V TVS in SMB package offering higher surge power margin; usable if board space allows the slightly larger footprint.
  • 1SMA15CAT3G --: SMA-packaged bidirectional 15V TVS diode with similar electrical characteristics, suitable drop-in replacement for general protection.
  • SMAJ15CA --: Same SMA package, 400W bidirectional TVS with 15V standoff voltage; direct functional equivalent from a major supplier.
  • SMBJ15CA --: Bidirectional 15V TVS in SMB package with higher 600W surge rating; suitable upgrade if board space allows.
  • 1.5SMC15CA --: 1500W bidirectional TVS with 15V standoff in SMC package; robust alternative when higher surge capability is acceptable.
