Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMB12A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay.  

**Specifications:**  
- **Part Number:** TPSMB12A  
- **Manufacturer:** Vishay  
- **Type:** Unidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 600 W  
- **Breakdown Voltage (VBR):** 13.3 V (min), 14.7 V (max)  
- **Standoff Voltage (VRWM):** 12 V  
- **Clamping Voltage (VCL):** 19.9 V at 10 A  
- **Peak Pulse Current (IPP):** 38.5 A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

**Descriptions and Features:**  
- Designed for surge protection in electronic circuits.  
- Provides protection against voltage transients, ESD, and inductive load switching.  
- Low incremental surge resistance for effective clamping.  
- RoHS-compliant and halogen-free.  
- Suitable for applications in automotive, telecommunications, and industrial systems.  

For detailed electrical characteristics and mechanical dimensions, refer to the Vishay datasheet.

Alternative Part Number

  • SMBJ12A --: Same SMB (DO-214AA) package and 12V standoff unidirectional TVS diode with comparable clamping performance, widely available and pin-compatible.
  • P6SMB12A --: 600W SMB-packaged unidirectional TVS diode with 12V standoff voltage, matching the surge rating class and footprint of the original.
  • 1SMB12AT3G --: SMB unidirectional TVS diode with 12V standoff and similar power handling, a common cross-reference for SMBJ/TPSMB series parts.
