Single Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm surface-mount packaging and MIL-PRF-19500 screening status if required. Ensure compatibility with existing PCB footprints for the DO-213AA package. Confirm RoHS compliance requirements as indicated in the datasheet. Validate that the 50 V rating meets system voltage constraints. Check for any recent product change notices affecting pinout or material composition.

Single Diodes Selection Notes

Select this component when a fast-recovery diode is needed for low-voltage, high-speed digital environments. The 4 ns recovery time makes it suitable for applications where standard rectifiers would introduce excessive delay. Consider the 200 mA continuous current limit for load requirements. The wide operating temperature range allows use in harsh environments without derating. Compare against similar series parts like the 1N4148 if through-hole mounting is acceptable.

Single Diodes Part Context

This part belongs to the 1N4150 family of silicon epitaxial planar diodes manufactured by Microchip Technology. It serves as the surface-mount equivalent to traditional through-hole switching diodes. The series is widely recognized for its reliability in computer and communication systems. Microchip maintains strict quality controls for this line, often offering screened versions for military and aerospace applications.

Single Diodes Replacement Considerations

The 1N4150 (through-hole) is the direct leaded counterpart. Verify pinout compatibility before substitution. Other fast-switching diodes may require voltage and current derating checks.
