Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMB43A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 36.8V  
- **Voltage - Breakdown (V_BR):** 40.9V (Min)  
- **Voltage - Clamping (V_CL):** 58.1V at 38.9A  
- **Peak Pulse Current (I_PP):** 38.9A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 1500W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

### **Descriptions & Features:**  
- Designed to protect sensitive electronics from voltage transients and ESD events.  
- Low clamping voltage for effective overvoltage protection.  
- Fast response time for surge suppression.  
- RoHS-compliant and halogen-free.  
- Suitable for applications in automotive, industrial, and consumer electronics.  

For detailed datasheet information, refer to Vishay's official documentation.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • SMBJ43A --: Same SMB (DO-214AA) package and 43V standoff unidirectional TVS diode with comparable clamping performance, widely available and pin-compatible.
  • P6SMB43A --: 600W SMB-packaged unidirectional TVS with 43V standoff voltage, matching the TPSMB43A's surge rating and footprint for drop-in replacement.
  • SMAJ43A --: 43V unidirectional TVS in SMA package offering similar clamping characteristics; usable alternative where slightly lower power rating is acceptable.
