Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors The **P4SMA100CA** from **GS** is a high-performance **TVS diode** designed to protect sensitive electronic circuits from transient voltage spikes. This surface-mount component offers robust **ESD and surge protection** with a **standoff voltage of 100V** and a **peak pulse power dissipation of 400W**.  

Featuring a **low clamping voltage**, the P4SMA100CA ensures minimal stress on downstream components while effectively diverting harmful transients. Its fast response time—typically in **picoseconds**—makes it ideal for safeguarding high-speed data lines, power supplies, and communication interfaces.  

The diode is housed in a **SMA (DO-214AC) package**, providing a compact footprint suitable for space-constrained PCB designs. With **bidirectional polarity**, it simplifies circuit integration by eliminating the need for orientation-specific placement.  

Common applications include **industrial automation, automotive electronics, and consumer devices**, where reliable overvoltage protection is critical. The P4SMA100CA meets industry standards for reliability and performance, ensuring long-term stability in harsh environments.  

Engineers value this component for its **balance of protection efficiency, compact size, and cost-effectiveness**, making it a preferred choice for modern electronic designs requiring robust transient suppression.

Alternative Part Number

  • SMAJ100CA --: Same SMA package bidirectional 100V TVS diode with comparable clamping and power rating, widely available and pin-compatible.
  • SMBJ100CA --: Bidirectional 100V TVS in SMB package offering higher surge capability; usable if board space allows the slightly larger footprint.
  • 1SMA100CAT3G --: SMA-packaged bidirectional 100V TVS diode with similar electrical characteristics, suitable drop-in replacement from a different series.
  • SMAJ100CA --: Same SMA package bidirectional 100V TVS diode with comparable clamping voltage and power rating, widely available from a major supplier.
  • SMBJ100CA --: Bidirectional 100V TVS in SMB package offers higher surge capability and is a common drop-in upgrade when board space allows.
  • P6SMB100CA --: 600W bidirectional 100V TVS in SMB package provides similar protection with higher peak pulse power for robust designs.
