The 1 V forward voltage drop at 400 mA forward current gives a conduction loss of about 0.4 W at that point — well within the DO-35 package's dissipation capability for most board-level designs. Reverse leakage is specified at 50 nA maximum when 225 V is applied across the junction. This low leakage matters in high-impedance bias circuits or where the diode sits across a power rail that must not back-feed into a low-current source. ## Military qualification and sourcing posture The 1N6661 is qualified to MIL-PRF-19500/587, the military standard for semiconductor diodes. This means the part has passed the screening, burn-in, and group A/B/C testing required for high-reliability applications — avionics, ground-support equipment, and defence electronics where lot traceability and failure-rate data are contractually required.","metaTitle":"1N6661 Microchip Technology Standard Recovery Diode, 500mA","metaDescription":"1N6661 standard recovery diode, 500mA average rectified current, 225V reverse voltage, DO-35 axial package.
