UA1A

Single Diodes Overview

The UA1A is a 50 V, 1 A surface mount avalanche diode manufactured by SMC Diode Solutions. It utilizes the DO-214AC (SMA) package for through-hole or surface-mount integration. The component is designed to handle repetitive peak reverse voltage of 50 V and an average forward rectified current of 1 A. It operates within a junction temperature range of -55°C to +175°C. The device features glass passivation for environmental protection and meets RoHS standards.

Single Diodes Procurement Notes

Verify the specific datasheet version for the UA1A to confirm exact electrical limits and thermal resistance values. Ensure the DO-214AC footprint matches the PCB design. Confirm RoHS compliance status with the supplier if required for specific regulatory environments. Check for any recent product change notices that may affect pinout or material composition.

Single Diodes Selection Notes

Select the UA1A when a 50 V rating and 1 A current capacity are required in a compact SMA package. Consider its avalanche capability if the circuit experiences transient voltage spikes. Compare thermal performance against other SMA diodes if heat dissipation is a critical constraint in the enclosure design.
