Description and Introduction

PLASTIC SURFACE MOUNT ZENER DIODES 3 WATTS 3.3.200 VOLTS The part 1SMB5945BT3 is a surface-mount transient voltage suppressor (TVS) diode manufactured by ON Semiconductor. It is designed to protect sensitive electronics from voltage transients and electrostatic discharge (ESD). Key specifications include:

- **Peak Pulse Power Dissipation (PPP):** 1500 W (10/1000 µs waveform)
- **Standoff Voltage (VWM):** 85.5 V
- **Breakdown Voltage (VBR):** 95 V (min) to 105 V (max)
- **Clamping Voltage (VC):** 137 V at 16.4 A
- **Reverse Leakage Current (IR):** 1 µA (max) at VWM
- **Operating Temperature Range:** -55°C to +150°C
- **Package:** SMB (DO-214AA)

This diode is commonly used in applications such as telecommunications, automotive, and industrial systems for overvoltage protection.
