Overview
The Microchip Technology 1N5297/TR is a current regulator diode designed for through-hole mounting in the DO-7 (DO-204AA) axial leaded package. It provides a regulated current of 1.21 mA with a maximum power dissipation of 500 mW and a maximum anode-to-cathode voltage rating of 100 V. The device operates within a junction temperature range of -65°C to +175°C. This component belongs to the 1N5283-1 through 1N5314-1 series, which offers standard 10% tolerance current regulation across a broad voltage range.
Feature Summary
- Provides constant current regulation over a wide voltage range
- Utilizes double-plug internal bond connection for enhanced reliability
- Qualified per MIL-PRF-19500/463 military standards
Applications
- Military electronic systems requiring stable current sources
- High-reliability industrial circuits needing constant current biasing
- Spacecraft avionics and aerospace instrumentation
Procurement Notes
Verify that the specific suffix /TR indicates tape and reel packaging when sourcing. Confirm the manufacturer's official datasheet for the 1N5283-1 through 1N5314-1 series to ensure all electrical parameters match design requirements. Check for RoHS compliance status as military variants may differ from commercial equivalents.
Selection Notes
Select this part when a fixed current source is required instead of a voltage reference. Ensure the circuit voltage does not exceed the 100 V maximum rating. Verify that the 500 mW power dissipation capability accommodates the thermal conditions of the application environment.
Part Context
This component is part of the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices serve as counterparts to Zener diodes by regulating current over a broad voltage range rather than voltage over a broad current range. The series includes various current values from 0.22 mA to 4.7 mA.
Replacement Considerations
Compatible substitutes include other parts from the 1N5283-1 through 1N5314-1 series manufactured by Microchip or qualified vendors. Ensure any replacement meets the MIL-PRF-19500/463 qualification if military grade is required.
