3.6 V Zener for reference and clamping
The 1N6486 is a 3.6 V Zener diode in the standard DO-204AL (DO-41) axial-lead package, rated for 1.5 W continuous power dissipation. That power rating means it can handle steady-state dissipation in a voltage-reference or shunt-clamp circuit without needing a heatsink — the DO-41 body sheds the heat through the leads into the PCB traces. Common deployment: on a low-voltage rail where you need a tight 3.6 V reference for an ADC or comparator threshold, or as a primary-side clamp on a 3.3 V logic supply that sees transients from an inductive load. Maximum impedance (Zzt) is 10 Ohms at the test current — this is the dynamic resistance at the nominal Zener voltage. A 10 Ohm Zzt at 3.6 V means the regulation slope is about 28 mV per mA of load change; for a simple shunt reference drawing 5 mA, the output shifts roughly 140 mV from no-load to full-load. That matters if you are using it as a precision reference rather than just a clamp. Reverse leakage is specified at 50 µA maximum at 1 V reverse bias — that is well below the Zener knee, so in a reverse-polarity protection circuit the diode draws negligible current until the voltage climbs past the breakdown region.
Active lifecycle and sourcing
Packaged in Bulk (not tape-and-reel), so it ships as loose axial-lead parts. For a through-hole assembly line, bulk packaging means hand-insertion or tube-fed auto-insertion; verify your pick-and-place or wave-solder feeder handles axial components in bulk format before committing the line.
