Junction temperature range — -55°C to 150°C
The operating junction temperature spans -55°C to 150°C, covering military-temperature applications. That makes this part a candidate for avionics power supplies, satellite DC-DC converters, or downhole instrumentation where the ambient can swing well beyond industrial limits. The TO-220 Full Pack isolates the tab electrically, so no insulating pad is needed between the device and the heatsink — a time-saver in assembly and a reliability gain in high-vibration environments.
Lifecycle and sourcing — active, no LTB risk
The SPA15N65C3 carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy window is announced, and no successor has been issued — this is a current-production part you can qualify into a new BOM without worrying about a forced redesign mid-cycle.
