Description and Introduction

TRANSIL The SM15T39CA is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Part Number:** SM15T39CA  
- **Manufacturer:** Vishay  
- **Type:** Bidirectional TVS Diode  
- **Working Peak Reverse Voltage (VRWM):** 33.2 V  
- **Breakdown Voltage (VBR):** 36.8 V (min) to 40.7 V (max)  
- **Clamping Voltage (VC):** 62.1 V at 24.2 A (IPP)  
- **Peak Pulse Current (IPP):** 24.2 A (8/20 µs waveform)  
- **Maximum Reverse Leakage Current (IR):** 1 µA (at VRWM)  
- **Power Dissipation (PPK):** 1500 W (peak pulse)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration for clamping both positive and negative voltage spikes.  
- Low incremental surge resistance for effective clamping.  

### **Features:**  
- High surge capability (1500 W peak pulse power).  
- Fast response time (pico-second range).  
- RoHS compliant and halogen-free.  
- Suitable for automotive, industrial, and telecom applications.  

This information is based on Vishay's datasheet for the SM15T39CA.

Alternative Part Number

  • 1.5SMC39CA --: Same 1500W SMC package bidirectional TVS with 39V standoff, direct electrical equivalent from a different series.
  • SMCJ39CA --: 1500W SMC bidirectional TVS diode with 39V standoff voltage, widely available and functionally interchangeable.
  • P6SMB39CA --: 600W SMB bidirectional TVS with 39V standoff; lower power rating but usable in less demanding clamping applications.
