Description and Introduction

TRANSIL The **SMAJ58A-TR** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 58V  
- **Voltage - Breakdown (V_BR):** 64.4V (min)  
- **Voltage - Clamping (V_CL):** 93.6V at 10A (I_PP)  
- **Peak Pulse Current (I_PP):** 10A (8/20μs)  
- **Power - Peak Pulse (P_PP):** 600W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** **DO-214AC (SMA)**  
- **Polarity:** **Unidirectional**  

### **Descriptions:**  
- Designed to protect sensitive electronics from **voltage transients** and **ESD events**.  
- Suitable for **automotive, industrial, and consumer applications**.  
- **RoHS compliant** and **halogen-free**.  

### **Features:**  
- **Low clamping voltage** for effective protection.  
- **Fast response time** (typically <1ns).  
- **High surge capability** (up to 10A peak pulse current).  
- **Reliable performance** under harsh conditions.  

This TVS diode is commonly used in **power supplies, communication ports, and automotive systems** to prevent damage from voltage spikes.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • SMAJ58A-E3/61 --: Same SMAJ series 58V unidirectional TVS diode with identical 400W peak pulse rating and SMA package, widely available from Vishay as a direct form-fit-function substitute.
  • P6SMB58A --: 600W SMB package unidirectional TVS with 58V standoff voltage; higher surge rating provides margin while remaining electrically compatible in most clamping applications.
  • SMBJ58A --: 600W SMB unidirectional TVS diode with 58V working voltage, common industry-standard alternative offering similar clamping characteristics and easy drop-in replacement.
