Current Regulation - Diodes, Transistors Procurement Notes

Verify the JANS suffix indicates military-grade qualification requirements specific to this part number. Confirm the TR suffix denotes tape and reel packaging rather than bulk. Ensure the DO-7 axial lead form matches your PCB layout constraints. Cross-reference the datasheet for thermal derating curves at elevated ambient temperatures. Validate that the 616µA current tolerance meets your circuit design specifications before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 616µA current source is required in harsh environments. The wide temperature range makes it suitable for extreme conditions where standard diodes may fail. Consider the DO-7 package size for space-constrained through-hole designs. Evaluate the 100V breakdown voltage against peak transient voltages in the application. Compare performance against other JANS series parts for potential cost or availability optimizations.
