Description and Introduction

Silicon Avalanche Diodes - 400W Surface Mount Transient Voltage Supressors **Introduction to the P4SMA120CA TVS Diode from VISHAY**  

The P4SMA120CA is a surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and electrostatic discharge (ESD). Manufactured by VISHAY, this bidirectional diode offers robust clamping performance with a standoff voltage of 120V and a peak pulse power rating of 400W.  

Featuring a compact SMA (DO-214AC) package, the P4SMA120CA is ideal for space-constrained applications, including power supplies, communication systems, and industrial electronics. Its low clamping voltage ensures effective suppression of transient overvoltages, safeguarding downstream components from damage.  

Key specifications include a breakdown voltage range of 133V to 147V and a fast response time, making it suitable for high-speed data lines and surge-prone environments. The device meets industry standards for reliability and performance, ensuring consistent protection in demanding conditions.  

With its combination of high power handling, precise voltage regulation, and compact form factor, the P4SMA120CA is a dependable solution for circuit protection in automotive, telecommunications, and consumer electronics applications. Its bidirectional operation simplifies design implementation, providing versatile overvoltage defense in both polarities.  

Engineers seeking a robust, space-efficient TVS diode will find the P4SMA120CA a practical choice for enhancing system resilience against electrical transients.

Alternative Part Number

  • SMAJ120CA --: Same SMA package bidirectional 120V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ120CA --: Bidirectional 120V TVS in SMB package offering higher surge power margin; can replace with minor footprint adjustment.
  • 1SMA120CA --: SMA-packaged bidirectional 120V TVS diode with similar electrical characteristics and a different series naming for easy distinction.
  • SMAJ120CA --: Same SMA package bidirectional 120V TVS diode with comparable clamping voltage and power rating, widely available and pin-compatible.
  • SMBJ120CA --: Bidirectional 120V TVS in SMB package offering higher surge power margin; can replace SMA part where board space allows.
  • 1SMA120CAT3G --: SMA-packaged bidirectional 120V TVS diode from a major supplier, electrically similar and suitable as a drop-in alternative.
