1N1253

Single Diodes Overview

The Microchip Technology 1N1253 is a general-purpose silicon rectifier diode designed for power rectification and switching applications. It features a maximum average forward rectified current of 500mA and a repetitive peak reverse voltage (Vrrm) of 200V. The device utilizes a stud mount configuration within the DO-203AA (DO-4) package, ensuring robust mechanical stability for high-power environments. Its fast recovery characteristics, typically in the range of 100 to 500 nanoseconds, make it suitable for efficient voltage clamping and general switching functions in various electronic circuits.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as multiple vendors produce this standard part number. Confirm the package type matches your thermal and mechanical requirements. Ensure the datasheet specifies the exact recovery time class required for your circuit design. Check for any suffix variations that may indicate different testing conditions or packaging options.

Single Diodes Selection Notes

Select this component when a 500mA current rating and 200V reverse voltage are sufficient for the load. The stud mount style requires appropriate heatsinking and mounting hardware. Consider the forward voltage drop and thermal resistance if operating near maximum ratings. Verify compatibility with the existing PCB or chassis layout due to the specific package dimensions.

Single Diodes Part Context

This diode belongs to the standard 1N series of rectifiers, widely used in industrial and consumer electronics. It serves as a reliable solution for low-to-medium power AC-to-DC conversion. The DO-203AA package is a legacy but robust form factor often found in older equipment designs or specialized industrial controls requiring durable connections.

Single Diodes Replacement Considerations

Equivalent parts include other 500mA, 200V stud-mount diodes from manufacturers like Vishay or ON Semiconductor. Ensure replacement devices match the physical mounting hole pattern and terminal configuration. Verify that the replacement's reverse leakage current and forward voltage specifications meet the original design constraints.
