Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMB20A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Vishay  
- **Type:** TVS Diode (Transient Voltage Suppressor)  
- **Peak Pulse Power (10/1000μs):** 600 W  
- **Standoff Voltage (VWM):** 17.1 V  
- **Breakdown Voltage (VBR):** 19.0 V (min)  
- **Clamping Voltage (VC):** 27.7 V at 1 A  
- **Reverse Leakage Current (IR):** 1 μA (max) at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bi-directional TVS diode, providing protection for both positive and negative voltage spikes.  
- RoHS compliant and halogen-free.  

### **Features:**  
- Low clamping voltage for effective transient suppression.  
- High surge capability.  
- Fast response time to transient events.  
- Surface-mount package for compact PCB designs.  

This information is strictly factual and sourced from Vishay's product documentation.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • SMBJ20A --: Same SMB (DO-214AA) package unidirectional TVS diode with 20V standoff voltage and comparable clamping performance; widely available and pin-compatible.
  • P6SMB20A --: SMB-package unidirectional TVS with 20V standoff and 600W peak pulse rating, matching the TPSMB20A's surge capability and footprint.
  • SMAJ20A --: Unidirectional 20V TVS diode with similar electrical characteristics; slightly smaller SMA package but usable as a drop-in substitute where board space allows.
