Description and Introduction

SURFACE MOUNT UNIDIRECTIONAL AND BIDIRECTIONAL TRANSIENT VOLTAGE SUPPRESSORS The SMAJ70CA is a bidirectional TVS (Transient Voltage Suppressor) diode manufactured by Fairchild Semiconductor (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Voltage - Reverse Standoff (V_RWM):** 70V  
- **Voltage - Breakdown (V_BR):** 77.8V (min)  
- **Voltage - Clamping (V_C):** 113V (max) at 10A  
- **Peak Pulse Current (I_PP):** 10A (8/20μs waveform)  
- **Power - Peak Pulse (P_PP):** 400W  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AC (SMA)  

### **Description:**  
The SMAJ70CA is designed to protect sensitive electronics from high-voltage transients, such as ESD (Electrostatic Discharge), lightning, and inductive load switching. It is bidirectional, meaning it clamps both positive and negative transient voltages.  

### **Features:**  
- **Low Clamping Voltage:** Provides effective protection for sensitive circuits.  
- **Fast Response Time:** Responds quickly to transient events (typically <1ns).  
- **High Surge Capability:** Can handle high peak pulse currents.  
- **Bidirectional Operation:** Protects against both positive and negative transients.  
- **RoHS Compliant:** Meets environmental standards.
