JANS1N5308-1/TR

Current Regulation - Diodes, Transistors Overview

The JANS1N5308-1/TR is a current regulator diode manufactured by Microchip Technology, designed for high-reliability applications. It operates within a military qualification standard and features a maximum peak operating voltage of 100 V with a regulated current of 2.97 mA. The device dissipates up to 500 mW and functions across an extended temperature range from -65°C to +175°C. Packaged in the DO-204AA (DO-7) axial leaded format on a tape and reel, it provides stable current regulation over a broad voltage range, serving as a counterpart to Zener diodes which regulate voltage.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and reel specifications. Ensure the component meets the required JANS radiation hardness levels for the intended deployment environment. Cross-reference the part number with the latest Microchip documentation to validate availability and manufacturing status before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required over a wide voltage span rather than voltage regulation. Compare the 2.97 mA rating against circuit load requirements. Verify that the DO-7 through-hole package fits the board layout constraints. Confirm thermal dissipation limits are respected within the operational temperature envelope.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5-watt current regulators produced by Microchip. These devices offer standard 10% tolerance currents ranging from 0.22 mA to 4.7 mA. The series is widely recognized for providing reliable current limiting in axial-leaded packages suitable for harsh environments.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include JAN1N5308-1, JANTX1N5308-1, and JANTXV1N5308-1. Verify that the alternative grade meets the specific radiation hardness and quality assurance requirements of the original JANS specification.
