Procurement Notes
Verify the specific suffix and package type against official Microchip documentation before procurement. Confirm RoHS compliance status as indicated in the datasheet. Ensure the through-hole mounting style matches the target PCB design requirements. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and supply chain integrity.
Selection Notes
Select this component when high-speed switching performance is required alongside wide thermal stability. The 7 ns recovery time distinguishes it from standard rectifiers. Verify that the 50 V reverse voltage rating exceeds the circuit's peak inverse voltage. Ensure the 250 mA continuous forward current meets the load requirements without exceeding thermal limits.
Part Context
This component belongs to the general purpose diode family manufactured by Microchip Technology. It is categorized under small signal switching diodes intended for discrete semiconductor applications. The product line supports industrial and computing markets requiring reliable signal control components.
Replacement Considerations
Consult official cross-reference tools for verified substitutes. Ensure any replacement matches the 50 V reverse voltage, 250 mA forward current, and 7 ns recovery time specifications.
