Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMA22 is a unidirectional surface mount transient voltage suppressor (TVS) diode manufactured by WPI (World Products Inc.).  

### **Specifications:**  
- **Type:** Unidirectional TVS Diode  
- **Peak Pulse Power:** 400W (10/1000µs)  
- **Standoff Voltage (VWM):** 19.9V  
- **Breakdown Voltage (VBR):** 22.1V (Min)  
- **Clamping Voltage (VC):** 32.4V at 10A  
- **Maximum Reverse Leakage Current (IRM):** 1µA  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMA (DO-214AC)  

### **Descriptions and Features:**  
- Designed for overvoltage protection in sensitive electronics.  
- Fast response time for transient suppression.  
- Low leakage current for improved efficiency.  
- RoHS compliant.  
- Suitable for applications such as power supplies, communication systems, and automotive electronics.

Alternative Part Number

  • SMAJ22A --: Same SMA package unidirectional TVS diode with 22V standoff voltage and comparable clamping performance; widely available and pin-compatible.
  • P4SMA22A --: SMA-packaged 400W TVS diode with 22V standoff, matching the TPSMA22's surge rating and footprint for direct drop-in use.
  • SMAJ22CA --: Bidirectional 22V SMA TVS diode offering similar protection levels; suitable when bidirectional clamping is acceptable.
