Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMC30A is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Part Number:** TPSMC30A  
- **Manufacturer:** Vishay  
- **Type:** Transient Voltage Suppressor (TVS) Diode  
- **Package:** SMC (DO-214AB)  
- **Peak Pulse Power (10/1000μs):** 3000W  
- **Breakdown Voltage (VBR):** 33.3V (min) – 36.8V (max)  
- **Standoff Voltage (VRWM):** 30V  
- **Clamping Voltage (VC):** 48.4V at 10A  
- **Peak Pulse Current (IPP):** 62.5A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Polarity:** Unidirectional  

### **Description:**  
The TPSMC30A is designed to protect sensitive electronics from high-voltage transients, such as ESD, lightning, and inductive load switching. It offers fast response times and high surge capability in a compact SMC package.  

### **Features:**  
- **High Power Handling:** 3000W peak pulse power dissipation.  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond).  
- **RoHS Compliant:** Meets environmental standards.  
- **Surface-Mount Design:** Suitable for automated assembly processes.  

This information is based solely on Vishay's datasheet for the TPSMC30A TVS diode.

Application Scenarios & Design Considerations

Alternative Part Number

  • SMCJ30A --: Same SMC (DO-214AB) package, 30V standoff unidirectional TVS diode with comparable 1500W peak pulse power, direct functional drop-in replacement.
  • 1.5SMC30A --: 1500W unidirectional TVS in SMC package with 30V standoff voltage, matches the original's clamping and surge ratings for transient protection.
  • SMDJ30A --: 3000W SMC-package unidirectional TVS at 30V standoff; higher surge capability but same footprint and voltage, usable where extra margin is acceptable.
  • 1SMC30A --: SMC-packaged unidirectional 30V TVS with comparable peak pulse power and clamping characteristics, suitable as a functional replacement.
  • P6SMB30A --: Unidirectional 30V TVS with similar standoff and clamping voltage; smaller SMB package, so acceptable when board space allows and lower surge rating is tolerable.
