Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMCJ8.0A is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V_RWM):** 8.0V  
- **Voltage - Breakdown (V_BR):** 8.9V (Min)  
- **Voltage - Clamping (V_C):** 12.9V at 10A (Typical)  
- **Peak Pulse Current (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 1500W (8/20µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**
- The SMCJ8.0A is designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive load switching.  
- It is a unidirectional TVS diode, meaning it clamps positive transients only.  
- It meets the requirements of MIL-PRF-19500/543 and is qualified to JEDEC JESD22-A104.  

### **Features:**
- Low clamping voltage for superior protection.  
- Fast response time (typically <1.0ps).  
- High surge capability.  
- RoHS compliant.  
- Lead-free and halogen-free options available.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • 1.5SMC8.0A --: Same 8.0V standoff unidirectional TVS in the SMC (DO-214AB) package with higher 1500W peak pulse power, a common drop-in upgrade from the 1500W SMCJ series.
  • P6SMB8.0A --: 8.0V unidirectional TVS diode with 600W peak pulse power in the SMB (DO-214AA) package; electrically similar clamping behavior and widely available alternative.
  • SMAJ8.0A --: 8.0V unidirectional TVS in the SMA (DO-214AC) package with 400W peak pulse power; suitable for lower-surge applications and a different series naming for easy identification.
