1N4305 is listed in the Single Diodes range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE STANDARD 75V 200MA DO7. Review the specifications below when checking this part for your BOM.
The Microchip Technology 1N4305 is a small signal switching diode designed for computer and general-purpose applications. It features a single configuration housed in the DO-35-2 through-hole package. Key electrical parameters include a peak reverse voltage of 75 V, a maximum forward current of 10 mA, and a maximum surge current of 500 mA. The device exhibits a fast recovery time of 2 ns with a forward voltage of 850 mV at rated current. Reverse leakage current is limited to 100 nA, and maximum diode capacitance is 2 pF. Operating temperatures range from -65 C to +150 C.
Verify RoHS compliance status carefully as documentation indicates non-compliance for certain variants like the 1N4305-1. Confirm specific ordering suffixes such as TR or -1 to ensure correct packaging and regulatory alignment. Cross-reference datasheets for exact electrical limits before integration.
Select this component when a standard silicon switching diode with 75 V reverse voltage rating is required. Ensure the DO-35-2 axial leaded package fits the PCB layout constraints. Verify that the 10 mA continuous forward current meets the circuit load requirements without exceeding thermal limits.
This part belongs to the standard 1N series of switching diodes manufactured by Microchip Technology. It serves as a fundamental discrete semiconductor component for signal processing and protection tasks within broader electronic systems.
Public confirmed substitute: 1N4454 (onsemi). Verify pinout compatibility and electrical parameter equivalence before substitution.
