概要
Description
The SMBJ5.0A is a 5.0V surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes, such as ESD (electrostatic discharge) and lightning-induced surges. Key features include:
- Breakdown Voltage (VBR): ~5.5V (min)
- Clamping Voltage (VC): ~9.2V at 5A
- Peak Pulse Current (IPP): 5A (8/20µs waveform)
- Low Leakage Current: <1µA
It is commonly used in USB ports, power supplies, and communication lines for overvoltage protection. The SMB package (DO-214AA) ensures compact PCB integration.
For detailed specs, refer to the datasheet from manufacturers like Littelfuse, Vishay, or STMicroelectronics.
