Description and Introduction

TRANSIL The **SMAJ48A-TR** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Voltage - Reverse Standoff (Vr):** 48V  
- **Voltage - Breakdown (Vbr):** 53.3V (Min)  
- **Voltage - Clamping (Vc):** 77.4V (Max) at 10A  
- **Peak Pulse Current (Ipp):** 10A (8/20µs)  
- **Power - Peak Pulse (Ppp):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  
- **Mounting Type:** Surface Mount  
- **RoHS Compliant:** Yes  

### **Descriptions & Features:**  
- Designed for **ESD and surge protection** in sensitive electronics.  
- **Low clamping voltage** for effective transient suppression.  
- **Fast response time** (typically <1ps) for quick protection.  
- **Unidirectional** TVS diode (protects against positive transients).  
- **High surge capability** for robust circuit protection.  
- Suitable for **telecommunications, automotive, and industrial applications**.  

This diode is commonly used to protect circuits from voltage spikes, ESD, and lightning-induced surges.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • SMAJ48A --: Same SMAJ series 48V unidirectional TVS diode with identical 400W peak pulse rating; widely available from a different manufacturer.
  • P4SMA48A --: 400W SMA-package unidirectional TVS with 48V standoff voltage, functionally equivalent and from a different series naming.
  • SMBJ48A --: 600W SMB-package 48V unidirectional TVS offering higher surge capability; suitable upgrade if board space allows SMB footprint.
