SMCJ30A

The SMCJ30A is a 30V surface-mount transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes and transients, such as ESD, lightning, and inductive load switching.
### Key Features:
- Standoff Voltage (VWM): 30V
- Breakdown Voltage (VBR): 33.3V (min)
- Peak Pulse Current (IPP): 24.2A (8/20µs)
- Low Clamping Voltage: Fast response to limit overvoltage
- Package: DO-214AB (SMC) for surface-mount applications
### Applications:
- ESD protection in data lines, power supplies, and communication ports
- Surge suppression in automotive, industrial, and consumer electronics
The SMCJ30A offers robust bidirectional protection, ensuring reliability in harsh environments. Its high surge capability and compact SMC package make it ideal for space-constrained designs.
