Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMCJ8.0CA is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 8.0V  
- **Voltage - Breakdown (V_BR):** 8.9V (min)  
- **Voltage - Clamping (V_C):** 12.9V at 10A (I_PP)  
- **Current - Peak Pulse (I_PP):** 10A (8/20µs)  
- **Power - Peak Pulse (P_PP):** 1500W (10/1000µs)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SMCJ8.0CA is a unidirectional TVS diode designed to protect sensitive electronics from transient voltage events such as ESD, lightning, and inductive load switching.  
- It is part of the SMCJ series, which offers high surge capability in a compact SMC package.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive components.  
- **High Surge Capability:** Handles large transient currents.  
- **Fast Response Time:** Reacts quickly to transient events.  
- **Unidirectional Polarity:** Protects against positive voltage transients.  
- **RoHS Compliant:** Meets environmental standards.  

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

Application Scenarios & Design Considerations

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS

Alternative Part Number

  • 1.5SMC8.0CA --: Same SMC (DO-214AB) package bidirectional TVS with 8.0V standoff; higher 1500W peak pulse rating gives extra margin and is a common drop-in upgrade.
  • P6SMB8.0CA --: Bidirectional 8.0V TVS in SMB (DO-214AA) package; lower profile and widely available, suitable when 600W clamping is acceptable.
  • SMAJ8.0CA --: Bidirectional 8.0V TVS in SMA (DO-214AC) package; compact alternative for space-constrained designs with 400W surge capability.
  • SMBJ8.0CA --: Widely available bidirectional 8.0V TVS in SMB package with comparable standoff and clamping voltages; 600W rating fits lighter surge environments.
  • SMDJ8.0CA --: Bidirectional 8.0V TVS in the same SMC/DO-214AB footprint rated at 3000W, offering greater surge margin while remaining electrically compatible.
