Description and Introduction

TRANSIL The SM4T15CA is a Transil™ diode manufactured by STMicroelectronics. It is designed for transient voltage suppression (TVS) applications.  

### **Specifications:**  
- **Type:** Uni-directional TVS diode  
- **Breakdown Voltage (VBR):** 16.7V (min) to 18.5V (max) at IT = 1mA  
- **Peak Pulse Power (PPP):** 400W (8/20μs)  
- **Clamping Voltage (VC):** 24.4V at IPP = 1A  
- **Standoff Voltage (VRWM):** 15V  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions & Features:**  
- Designed to protect sensitive electronics from voltage transients and ESD events.  
- Fast response time for effective clamping.  
- Low leakage current for power efficiency.  
- RoHS compliant and halogen-free.  
- Suitable for applications like automotive, industrial, and consumer electronics.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • SMAJ15CA --: Same 400W-class bidirectional TVS diode with 15V standoff voltage in SMA package, direct functional equivalent to the SM4T15CA.
  • P4SMA15CA --: 400W bidirectional transient voltage suppressor with 15V working voltage in SMA outline, matches the SM4T15CA ratings and package.
  • SMBJ15CA --: Bidirectional 15V TVS diode in SMB package with higher 600W surge rating, usable as a robust drop-in alternative where board space allows.
