Partnumber Manufacturer Quantity Availability
TPSMA12A 1000 In Stock

Description and Introduction

Surface Mount Automotive Transient Voltage Suppressors High Temperature Stability and High Reliability Conditions The TPSMA12A is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD).  

### **Manufacturer Specifications:**  
- **Manufacturer:** Littelfuse  
- **Peak Pulse Power (10/1000µs):** 400W  
- **Standoff Voltage (VWM):** 12V  
- **Breakdown Voltage (VBR):** 13.3V (min), 14.7V (max)  
- **Clamping Voltage (VCL):** 19.9V at 1A  
- **Maximum Reverse Leakage Current (IRM):** 1µA at VWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Descriptions:**  
The TPSMA12A is part of Littelfuse's TPSMA series, offering robust protection against transient overvoltage events. It features a low clamping voltage and fast response time, making it suitable for applications requiring ESD and surge protection.  

### **Features:**  
- **Unidirectional TVS Diode**  
- **Low Clamping Voltage**  
- **Fast Response Time** (<1ps)  
- **High Surge Capability**  
- **RoHS Compliant**  
- **AEC-Q101 Qualified** (for automotive applications)  

This diode is commonly used in power supplies, communication systems, and automotive electronics for transient voltage suppression.
