Description and Introduction

Bi-directional transient voltage protection The SMTBJ120B is a transient voltage suppressor (TVS) diode manufactured by LITTELFUSE. Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Part Number:** SMTBJ120B  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (PPP):** 600W (10/1000µs waveform)  
- **Breakdown Voltage (VBR):** 133V (min), 147V (max)  
- **Standoff Voltage (VRWM):** 120V  
- **Clamping Voltage (VC):** 193V at 10A  
- **Maximum Reverse Leakage Current (IR):** 1µA at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** DO-214AA (SMB)  

### **Description:**  
The SMTBJ120B is a surface-mount bidirectional TVS diode designed to protect sensitive electronics from voltage transients, including ESD, lightning, and inductive load switching. It provides high surge capability in a compact SMB package.  

### **Features:**  
- **Bidirectional Protection:** Guards against both positive and negative transient voltages.  
- **Low Clamping Voltage:** Helps limit voltage spikes to safe levels.  
- **High Surge Capability:** Handles up to 600W peak pulse power.  
- **Fast Response Time:** Reacts quickly to transient events (picosecond range).  
- **RoHS Compliant:** Meets environmental standards.  

This information is strictly based on the manufacturer's datasheet and product documentation.
