1N483A

Overview

The Microchip Technology 1N483A is a standard recovery rectifier diode designed for through-hole mounting in the DO-7 package. It features a maximum repetitive peak reverse voltage of 70 V and an average forward rectified current of 100 mA. The device dissipates up to 500 mW of power, with a maximum forward voltage drop of 1 V at rated current. It supports a surge current of 2 A and operates within a temperature range of -65°C to +175°C.

Feature Summary

• Standard recovery rectifier configuration suitable for general-purpose signal or computer diode applications
• Through-hole axial lead construction in a DO-7 package for reliable PCB integration
• High junction temperature capability extending operational limits up to +175°C

Applications

• Signal rectification circuits
• Computer logic interface protection
• General purpose DC power conversion

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as indicated in the product attributes table. Ensure the selected variant matches the required thermal dissipation and voltage ratings for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 70 V reverse voltage rating and 100 mA continuous current capacity are required. The DO-7 through-hole package is appropriate for manual assembly or standard wave soldering processes. Evaluate the 500 mW power dissipation limit against the expected thermal load in the application environment to ensure safe operating margins.

Part Context

The 1N483A belongs to the 1N48xx series of small-signal rectifiers manufactured by Microchip Technology. This series provides standardized performance characteristics for low-power switching and rectification tasks. The component serves as a fundamental discrete semiconductor element within electronic assemblies requiring reliable unidirectional current flow.

Replacement Considerations

Cross-reference equivalent part numbers from other manufacturers offering identical 70 V, 100 mA specifications in a DO-35/DO-7 axial package. Verify pinout compatibility and thermal resistance parameters to ensure functional equivalence without redesigning the host circuit board.
