Description and Introduction

Zener TVSs The SMCJ24A is a Transient Voltage Suppressor (TVS) diode manufactured by Microsemi. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Peak Pulse Power (PPP):** 1500W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 26.7V (min) to 29.5V (max)  
- **Standoff Voltage (VRWM):** 24V  
- **Clamping Voltage (VC):** 38.9V at 1A  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Junction Capacitance (CJ):** 2000pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMC)  

### **Descriptions:**
- The SMCJ24A is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive switching events.  
- It is a bidirectional TVS diode, meaning it can suppress both positive and negative voltage spikes.  
- The device is RoHS compliant and halogen-free.  

### **Features:**
- **High Surge Capability:** Handles large transient currents.  
- **Low Clamping Voltage:** Provides effective protection for downstream components.  
- **Fast Response Time:** Reacts quickly to transient events (typically <1ns).  
- **Bidirectional Operation:** Protects against overvoltage in both polarities.  
- **Robust Packaging:** DO-214AB (SMC) package for surface-mount applications.  

This information is sourced from Microsemi's official datasheet for the SMCJ24A TVS diode.

Application Scenarios & Design Considerations

Zener TVSs

Alternative Part Number

  • 1SMC24AT3G --: Same 1500W unidirectional TVS class with 24V standoff voltage, similar clamping performance and SMC package.
  • P6SMB24A --: 600W unidirectional TVS with 24V standoff; lower power rating but often acceptable for lower-surge designs and widely available.
  • SMAJ24A --: 400W unidirectional TVS with 24V standoff in SMA package; suitable only when reduced surge capability is acceptable.
