Description and Introduction

SMLJ Transient Voltage Suppressor Diode Series Here is the factual information about the **SMLJ45CA** manufactured by **Microsemi**:

### **Specifications:**
- **Part Number:** SMLJ45CA
- **Manufacturer:** Microsemi
- **Type:** Transient Voltage Suppressor (TVS) Diode
- **Configuration:** Unidirectional
- **Peak Pulse Power:** 1500W (10/1000μs)
- **Breakdown Voltage (VBR):** 50.1V (min) to 55.3V (max)
- **Standoff Voltage (VRWM):** 45V
- **Clamping Voltage (VC):** 73.2V at 10A
- **Peak Pulse Current (IPP):** 20.5A
- **Operating Temperature Range:** -55°C to +150°C
- **Package:** DO-214AB (SMC)

### **Descriptions:**
- The **SMLJ45CA** is a **unidirectional TVS diode** designed to protect sensitive electronics from high-voltage transients such as ESD, lightning, and inductive load switching.
- It provides **robust surge protection** with a **low clamping voltage** to ensure minimal stress on protected circuits.
- Suitable for applications requiring **high power dissipation** in a compact package.

### **Features:**
- **High surge capability** (1500W peak pulse power)
- **Fast response time** to transient events
- **Low leakage current** at standoff voltage
- **RoHS compliant**
- **DO-214AB (SMC) package** for surface-mount assembly
- **Unidirectional polarity** for protection against positive transients

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

Application Scenarios & Design Considerations
