Current Regulation - Diodes, Transistors Procurement Notes

Verify that the ordering suffix -1/TR corresponds to the specific MIL-PRF-19500/463 qualified variant and tape-and-reel packaging. Confirm RoHS exemption status as military parts often fall outside standard compliance. Validate supplier authorization for controlled military components before purchase.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable microampere-level reference current is required in space-constrained surface-mount designs. Ensure the circuit voltage does not exceed the 100 V maximum rating. Consider thermal management within the 500 mW dissipation limit during high-temperature operation up to 175°C junction temperature.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5285 series of current regulator diodes produced by Microchip Technology. The JANTXV prefix indicates a specific military qualification level, while the -1 suffix typically denotes the MIL-PRF-19500/463 standard. The /TR suffix specifies tape-and-reel packaging for surface-mount technology.
