Description and Introduction

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 150 V. Test current IT = 1 mA. The SMBJ150A is a transient voltage suppressor (TVS) diode manufactured by FAIRCHILD. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Peak Pulse Power Dissipation (Pppm):** 600W (10/1000μs waveform)  
- **Breakdown Voltage (VBR):** 166.7V (min) – 185.2V (max)  
- **Standoff Voltage (VRWM):** 150V  
- **Maximum Clamping Voltage (VC):** 243V at 1A  
- **Maximum Reverse Leakage Current (IR):** 1μA at VRWM  
- **Junction Capacitance (CJ):** 50pF (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
- The SMBJ150A is designed to protect sensitive electronics from high-voltage transients.  
- It is a unidirectional TVS diode, meaning it clamps positive transients only.  
- The device is compliant with RoHS standards.  

### **Features:**  
- **Low Clamping Voltage:** Ensures effective protection for sensitive components.  
- **Fast Response Time:** Reacts quickly to transient events (typically <1ps).  
- **High Surge Capability:** Can handle large transient currents.  
- **SMB Package:** Compact surface-mount design for space-constrained applications.  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

Surface mount transient voltage suppressor. 600 watts peak power. Reverse stand-off voltage VRWM = 150 V. Test current IT = 1 mA.

Alternative Part Number

  • P6SMB150A --: Same 600W SMB TVS class with 150V standoff and unidirectional clamping, widely available and pin-compatible.
  • 1SMB150AT3G --: SMB-packaged 150V unidirectional TVS with comparable surge rating, a common drop-in substitute.
  • SMAJ150A --: Similar 150V unidirectional TVS in SMA package; lower power rating but usable where 400W surge is sufficient.
