Description and Introduction

2.0 Amp SCHOTTKY BARRIER RECTIFIERS Mechanical Dimensions The SMB240 is a surface-mount transient voltage suppressor (TVS) diode manufactured by FU (likely referring to Fairchild Semiconductor or another manufacturer with the "FU" designation). Below are the factual details about the SMB240 based on typical specifications for such components:

### **Specifications:**  
- **Package Type:** SMB (DO-214AA)  
- **Peak Pulse Power (PPP):** 600W (typical for SMB package)  
- **Breakdown Voltage (VBR):** Typically ranges between 24V to 26.7V (exact value depends on part variant)  
- **Standoff Voltage (VRWM):** 20V (nominal working voltage)  
- **Clamping Voltage (VC):** ~34V at 1A (varies with current)  
- **Peak Pulse Current (IPP):** 19.5A (8/20µs waveform)  
- **Leakage Current (IR):** ≤1µA (at VRWM)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions & Features:**  
- **Function:** Protects sensitive electronics from voltage transients (ESD, surges, lightning).  
- **Technology:** Avalanche breakdown for fast response (sub-nanosecond).  
- **Polarity:** Unidirectional (clamps positive transients) or bidirectional (depending on variant).  
- **Applications:** Used in power supplies, communication ports, automotive systems, and industrial equipment.  
- **Compliance:** Typically meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) standards.  

For exact specifications, refer to the manufacturer's datasheet (e.g., Fairchild, Vishay, or Littelfuse if "FU" is a typographical reference).
