Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ58CA is a TVS (Transient Voltage Suppressor) diode manufactured by Vishay. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Peak Pulse Power (PPP):** 400 W (10/1000 µs waveform)  
- **Breakdown Voltage (VBR):** 64.4 V (minimum)  
- **Standoff Voltage (VRWM):** 58 V  
- **Maximum Clamping Voltage (VC):** 93.6 V at 10 A  
- **Reverse Leakage Current (IR):** 1 µA (maximum at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Junction Capacitance (CJ):** 50 pF (typical at 0 V, 1 MHz)  
- **Package Type:** DO-214AC (SMA)  

### **Description:**
The SMAJ58CA is a bidirectional TVS diode designed to protect sensitive electronics from voltage transients and surges, such as ESD (Electrostatic Discharge), lightning, and inductive load switching. It is compliant with automotive standards and provides robust protection in harsh environments.

### **Features:**
- **Bidirectional Protection:** Safeguards against both positive and negative voltage transients.  
- **Low Clamping Voltage:** Ensures minimal stress on protected circuits.  
- **Fast Response Time:** Reacts quickly to transient events (sub-nanosecond response).  
- **High Surge Capability:** Handles large transient currents.  
- **Automotive Grade:** Suitable for automotive applications (AEC-Q101 qualified).  
- **RoHS Compliant:** Environmentally friendly and lead-free.  

This information is strictly based on the manufacturer's datasheet and product specifications.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • SMBJ58CA --: Same 58V bidirectional TVS in a larger SMB package with higher surge rating, widely available and a common drop-in upgrade for SMAJ58CA.
  • P6SMB58CA --: 600W bidirectional transient voltage suppressor with matching 58V standoff voltage, SMB package, suitable functional replacement for the 400W SMAJ58CA.
  • 1SMB58CA --: Bidirectional 58V TVS diode in SMB package with comparable clamping characteristics, a well-stocked alternative from a major supplier.
  • 1SMB58CAT3G --: 58V bidirectional TVS in SMB with similar surge capability, suitable drop-in replacement from a different series.
