1N5287

Overview

The Microchip Technology 1N5287 is a current regulator diode belonging to the 1N5283-1 through 1N5314-1 series. It provides a regulated current of 0.47 mA with standard 10% tolerance. The device features a maximum peak operating voltage of 100 V and a maximum limit voltage of 1.2 V. Rated for 500 mW power dissipation, it operates within a junction temperature range of -65°C to +175°C. Available in axial-leaded DO-7 (DO-204AA) packages, it serves as a constant current source counterpart to Zener diodes.

Feature Summary

Maintains stable current regulation across a broad voltage range
High source impedance ensures consistent current output
DO-7 packaging offers double-plug internal bond connection

Applications

Constant current sources for LED biasing
Current limiting protection circuits
Active load applications

Part Context

The 1N5287 is part of the popular 1N5283-1 thru 1N5314-1 series of 0.5 watt current regulators manufactured by Microchip Technology. This series provides a selection from 0.22 mA to 4.7 mA in standard 10% tolerances. These devices are designed to regulate current over a broad voltage range, offering a functional counterpart to Zener diodes which regulate voltage over a broad current range.

Replacement Considerations

Verify that the replacement component matches the 0.47 mA nominal current rating and 100 V maximum voltage. Ensure the package type is compatible with the existing DO-7 footprint. Confirm that the replacement meets the required -65°C to +175°C operating temperature range.
