Description and Introduction

Bi-directional transient voltage protection The SMTBJ100B is a transient voltage suppressor (TVS) diode manufactured by LITTELFUSE.  

**Specifications:**  
- **Part Number:** SMTBJ100B  
- **Manufacturer:** LITTELFUSE  
- **Type:** Bidirectional TVS Diode  
- **Peak Pulse Power (10/1000μs):** 100W  
- **Breakdown Voltage (VBR):** 100V (min)  
- **Standoff Voltage (VRWM):** 85V  
- **Clamping Voltage (VC):** 137V (max) at 1A  
- **Leakage Current (IR):** 1μA (max) at VRWM  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** SMB (DO-214AA)  

**Descriptions and Features:**  
- Designed to protect sensitive electronics from voltage transients and surges.  
- Bidirectional configuration for protection against both positive and negative voltage spikes.  
- Low clamping voltage for effective transient suppression.  
- RoHS compliant and halogen-free.  
- Suitable for applications in telecommunications, industrial, and automotive systems.  

For exact application details, refer to the official LITTELFUSE datasheet.

Application Scenarios & Design Considerations

Bi-directional transient voltage protection

Alternative Part Number

  • SMBJ100A --: Same SMBJ series 100V standoff TVS diode with tighter 5% clamping tolerance, widely available and a common drop-in for general transient protection.
  • P6SMB100A --: SMB (DO-214AA) packaged 100V TVS diode with similar peak pulse power rating, suitable as a functional replacement in the same footprint.
  • 1SMB100AT3G --: SMB-packaged 100V unidirectional TVS diode from an alternate vendor, offering comparable surge capability and pin-compatible mounting.
