Rated for 400 V reverse voltage and 1 A average forward current, it handles the common 250 VAC or 400 VDC bus rectification in power supplies up to about 100 W output, with the 1.5 V forward drop at 1 A setting the conduction loss at roughly 1.5 W — a figure that calls for adequate lead length or a small heatsink in still air. This means it is safe to specify into a new BOM without worrying about a forced redesign mid-production. The through-hole axial package (A, Axial) is a standard DO-41 or similar outline — the body is cylindrical with wire leads on both ends, designed for hand insertion or wave soldering. The bulk packaging means parts are loose in a bag or tube, not taped for automated placement. Board layout is straightforward: drill 0.8 mm to 1.0 mm holes on a 0.4-inch lead spacing, route the anode and cathode traces to handle 1 A continuous plus inrush, and keep the diode close to the transformer or inductor it snubs to minimise loop inductance that would otherwise extend the effective recovery time. ## Reverse leakage and thermal considerations At the full 400 V reverse rating, the 1N6536 leaks 10 µA maximum — a negligible 4 mW of standby loss, but one that doubles roughly every 10 °C junction rise, so at 125 °C the leakage approaches 160 µA and the associated power loss climbs to 64 mW, still small but no longer negligible in a no-load standby budget. The 1.5 V forward drop at 1 A is typical for a 400 V fast recovery diode in this current class; a Schottky would drop half that but cannot block 400 V, and an ultrafast silicon-carbide diode would drop about the same but switch in under 10 ns. The 1N6536 sits in the middle — fast enough for 50-100 kHz switching without the cost premium of SiC.","metaTitle":"1N6536 Fast Recovery Diode, 400V 1A, 30ns trr, Axial","metaDescription":"Microchip Technology 1N6536 standard fast recovery diode, 400V reverse, 1A average, 30ns trr.
