Schottky rectifier for 3 A rails
The 1N6864/TR is a Schottky diode rated for 80 V reverse voltage and 3 A average rectified forward current, with a forward drop of 700 mV at 3 A — that 700 mV is the conduction loss floor for a 3 A rail, so the thermal design needs to sink about 2.1 W at full load. It carries a fast recovery classification of ≤ 500 ns at > 200 mA, which makes it suitable for freewheeling and snubbing in switching supplies where the diode's reverse recovery time affects the switching loss and EMI.
Military-grade qualification
Built to the MIL-PRF-19500/620 specification, this diode is screened for military and aerospace applications — the qualification covers reliability testing, temperature cycling, and lot acceptance. The junction temperature range spans -65 to 125 °C, matching the military temperature band for avionics, satellite, and downhole equipment.
Through-hole axial package
Reverse leakage is 150 µA at the 80 V rated reverse voltage — this leakage doubles with every 10 °C junction rise, so at 125 °C the leakage current can dominate the thermal budget in a high-impedance circuit.
