• Power supply regulation modules

Procurement Notes

Verify the specific Zener voltage value against the official MCC datasheet for the 1N5376B-AP part number before integration. Confirm that the DO-15 package dimensions match the target PCB footprint. Ensure thermal management strategies account for the 5W power dissipation rating under maximum load conditions.

Selection Notes

Select this component when a 5-watt through-hole Zener diode is required for robust voltage clamping. The DO-15 package offers higher power handling compared to smaller surface-mount alternatives. Verify the specific breakdown voltage aligns with circuit requirements, as the base part number covers a range of voltages.

Part Context

This component is part of the broader 1N53xxB family produced by Micro Commercial Components. The family includes various Zener diodes ranging from 5.1V to 51V, all sharing similar mechanical and thermal characteristics. The 'AP' suffix typically denotes specific packaging or tape-and-reel configurations distinct from standard bulk options.
