Overview
The Microchip Technology 1N5293/TR is a current regulator diode designed for through-hole mounting. It provides a regulated current of 748 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. The device operates within a temperature range of -65 °C to +175 °C. It utilizes the DO-7-2 package configuration, ensuring reliable performance in various electronic circuits requiring stable current regulation.
Feature Summary
- Maintains constant current output across varying load conditions
- Supports high-temperature operation up to 175 °C
- Utilizes through-hole technology for robust mechanical mounting
Applications
- Biasing circuits for transistors and LEDs
- Current limiting protection in sensitive electronic components
- Constant current sources for analog signal processing
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches DO-7-2 requirements. Ensure storage conditions comply with moisture sensitivity levels. Validate batch codes for traceability. Consult authorized distributors for availability status as supply may be restricted.
Selection Notes
Select this component when a fixed current source near 748 µA is required. Ensure the circuit voltage does not exceed the 100 V maximum limit. Verify that the thermal environment supports operation up to 175 °C. Consider the DO-7-2 package dimensions for PCB layout compatibility. Compare with similar current regulators if precise current values differ slightly from design needs.
Part Context
This part belongs to the Microchip Technology current regulator diode family. It shares functional similarities with other devices in the series but differs in specific current ratings and package options. The 1N5293/TR designation indicates a specific trim level or packaging variant within the broader product line.
Replacement Considerations
Direct substitutes include JAN1N5283-1/TR (242 µA) and 1N5285/TR (279 µA), though current ratings differ. Verify electrical parameters match application requirements before substitution. No identical 748 µA through-hole alternative is listed in the provided data.
