Overview
The Microchip Technology 1N5313-1 is a current regulator diode designed for stable current control in electronic circuits. It operates with a maximum voltage of 100V and provides a regulated current of 4.73mA at a power dissipation of 500mW. The device features a limiting voltage of 2.75V and supports a wide operating temperature range from -65°C to 175°C (TJ). Packaged in the DO-204AA (DO-7) axial through-hole format, it is suitable for robust applications requiring consistent current regulation under varying load conditions.
Feature Summary
- Provides constant current regulation across a wide temperature range
- Utilizes axial through-hole packaging for reliable mounting
- Supports high junction temperature operation up to 175°C
Applications
- Constant current sources for LED driving
- Biasing networks for transistor amplifiers
- Current limiting protection in sensitive circuits
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS status as non-compliant if required by project standards. Ensure axial lead form factor matches PCB layout requirements before finalizing procurement orders.
Selection Notes
Select this component when a fixed current of 4.73mA is required within a 100V reverse voltage limit. Consider the DO-7 package size for through-hole assembly constraints. Evaluate thermal management needs given the 500mW power dissipation rating and extended temperature capability.
Part Context
This part belongs to the 1N5313 series of current regulator diodes manufactured by Microchip Technology. It serves as a specialized semiconductor device distinct from standard rectifier or Zener diodes, focusing specifically on maintaining a steady current flow regardless of voltage fluctuations within its operational limits.
Replacement Considerations
Direct substitutes include other 1N5313 variants from different manufacturers offering identical electrical characteristics. Verify pin compatibility and package dimensions before substitution to ensure seamless integration into existing designs without modification.
