Description and Introduction

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 100 V. Test current IT = 1 mA. The **SMCJ100A** is a **Transient Voltage Suppressor (TVS) Diode** manufactured by **Microsemi** (now part of **Microchip Technology**).  

### **Specifications:**  
- **Peak Pulse Power (PPP):** 1500W (10/1000μs waveform)  
- **Standoff Voltage (VWM):** 85.5V  
- **Breakdown Voltage (VBR):** 95V (min) – 105V (max)  
- **Clamping Voltage (VC):** 154V at 10A  
- **Maximum Reverse Leakage Current (IRM):** 1μA at VWM  
- **Junction Capacitance (CJ):** 500pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**  
- Designed to protect sensitive electronics from high-voltage transients.  
- Bidirectional TVS diode, providing protection for both positive and negative voltage surges.  
- Fast response time to transient events.  

### **Features:**  
- **High Surge Capability:** Handles large transient currents.  
- **Low Clamping Voltage:** Limits voltage spikes effectively.  
- **RoHS Compliant:** Meets environmental standards.  
- **Surface-Mount Package:** Suitable for automated assembly.  

This diode is commonly used in **telecommunications, automotive, and industrial applications** for **ESD and surge protection**.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 1500 watts peak power. Reverse stand-off voltage VRWM = 100 V. Test current IT = 1 mA.

Alternative Part Number

  • 1.5SMC100A --: Same 1500W peak pulse power, 100V standoff unidirectional TVS in the SMC (DO-214AB) package, widely available and a common drop-in replacement.
  • P6SMB100A --: 600W unidirectional TVS with 100V standoff; lower power rating but suitable for less demanding clamping needs and available in SMB package.
  • SMAJ100A --: 400W unidirectional TVS with 100V standoff in SMA package; a compact lower-power alternative when board space and surge energy are reduced.
  • 1SMC100A --: Same 1500W unidirectional TVS diode with 100V standoff voltage in the SMC package, from a different series naming, widely available and electrically equivalent.
