Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMB22A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. Below are the specifications, descriptions, and features based on Vishay's datasheet:

### **Specifications:**  
- **Peak Pulse Power (PPP):** 600 W (10/1000 μs waveform)  
- **Breakdown Voltage (VBR):** 24.4 V (min), 27 V (max) at 1 mA  
- **Standoff Voltage (VRWM):** 22 V  
- **Maximum Clamping Voltage (VC):** 38.9 V at 10 A  
- **Peak Pulse Current (IPP):** 15.4 A (8/20 μs waveform)  
- **Leakage Current (IR):** 1 μA (max) at VRWM  
- **Operating Temperature Range:** -55 °C to +150 °C  
- **Package:** DO-214AA (SMB)  

### **Description:**  
The TPSMB22A is a unidirectional TVS diode designed to protect sensitive electronics from voltage transients, such as ESD, lightning, and inductive load switching. It provides fast response times and high surge capability.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive circuits.  
- **High Power Handling:** 600 W peak pulse power dissipation.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **Surface-Mount Package (SMB):** Compact and suitable for automated assembly.  
- **RoHS Compliant:** Meets environmental standards.  

For detailed application notes and reliability data, refer to Vishay's official datasheet.

Application Scenarios & Design Considerations

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions

Alternative Part Number

  • SMBJ22A --: Same SMB (DO-214AA) package, 22V standoff unidirectional TVS with similar clamping voltage and power rating; widely available and pin-compatible.
  • P6SMB22A --: 600W SMB unidirectional TVS diode with 22V standoff, matching the TPSMB22A's surge capability and footprint for drop-in replacement.
  • 1SMB22AT3G --: SMB-packaged 22V unidirectional TVS with comparable peak pulse power and clamping characteristics, suitable as a functional substitute.
