Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ43CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by CCD (Comchip Technology). Here are the specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Part Number:** SMDJ43CA  
- **Manufacturer:** CCD (Comchip Technology)  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 1500W  
- **Breakdown Voltage (VBR):** 47.8V (min) – 52.9V (max)  
- **Standoff Voltage (VRWM):** 43V  
- **Clamping Voltage (VC):** 69.4V at 10A  
- **Peak Pulse Current (IPP):** 27.1A  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AB (SMDJ)  

### **Descriptions:**  
The SMDJ43CA is designed to protect sensitive electronics from voltage transients, including ESD, lightning, and other surge events. It offers bidirectional clamping, making it suitable for AC or DC circuits.  

### **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 (picosecond range).  
- **RoHS Compliant:** Meets environmental standards.  
- **AEC-Q101 Qualified:** Suitable for automotive applications.  

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

Description and Introduction

SURFACE MOUNT TRANSIENT VOLTAGE SUPPRESSOR The SMDJ43CA is a bidirectional Transient Voltage Suppressor (TVS) diode manufactured by LITTELFUSE. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Voltage - Reverse Standoff (V_RWM):** 38.5V  
- **Voltage - Breakdown (Min) (V_BR):** 42.8V  
- **Voltage - Clamping (Max) @ I_PP (V_C):** 69.4V @ 38.6A  
- **Current - Peak Pulse (10/1000µs) (I_PP):** 38.6A  
- **Power - Peak Pulse (10/1000µs):** 3000W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package / Case:** DO-214AB (SMC)  
- **Mounting Type:** Surface Mount  

### **Description:**
The SMDJ43CA is designed to protect sensitive electronics from high-voltage transients, including ESD, lightning, and inductive switching surges. It offers bidirectional protection, meaning it clamps both positive and negative voltage spikes.

### **Features:**
- **Bidirectional TVS Diode** – Protects against both positive and negative transients.  
- **High Surge Capability** – Handles peak pulse currents up to 38.6A.  
- **Low Clamping Voltage** – Limits voltage spikes to safe levels (69.4V max).  
- **Fast Response Time** – Reacts quickly to transient events (picosecond range).  
- **RoHS Compliant** – Meets environmental standards.  

This device is commonly used in power supplies, communication systems, and industrial electronics for surge protection.
