1N5305-1

Overview

The Microchip Technology 1N5305-1 is a current regulator diode designed for stable current control in electronic circuits. It operates with a maximum voltage of 100 V and provides a regulated current of 2.64 mA. The device features a power dissipation rating of 500 mW and utilizes the DO-7 axial through-hole package. It supports an operating temperature range from -65°C to +175°C junction temperature, ensuring reliability in demanding environments.

Feature Summary

• Provides constant current regulation across varying load conditions
• Supports high-temperature operation up to 175°C junction temperature
• Utilizes robust axial leaded package for through-hole mounting

Applications

• Biasing circuits requiring stable current sources
• LED driver applications for consistent brightness
• Protection circuits limiting current flow to sensitive components

Procurement Notes

Verify the specific suffix and packaging configuration when ordering, as availability may vary by distributor. Confirm RoHS compliance status directly with the manufacturer or authorized suppliers prior to procurement. Ensure that the selected component matches the required current and voltage specifications for the intended application design.

Selection Notes

Select this component when a fixed current source is required within a 100 V limit. Consider the 500 mW power dissipation capability and the DO-7 package size during layout planning. Verify thermal management requirements given the wide operating temperature range and ensure compatibility with existing through-hole assembly processes.

Part Context

This part belongs to the 1N53xx series of current regulator diodes manufactured by Microchip Technology. These devices are commonly used in general-purpose electronics where simple, reliable current limiting or biasing is needed without complex active circuitry. The series offers various current options to suit different design constraints.

Replacement Considerations

Check for direct equivalents such as other 1N5305 variants or generic CRD parts with matching 2.64 mA regulation and 100 V breakdown voltage. Ensure substitute components meet the same DO-7 package dimensions and thermal ratings for mechanical interchangeability.
