This qualification means the diode has passed screening and reliability testing for defense and aerospace applications, including temperature cycling, burn-in, and hermeticity where applicable. Rated for 50 V reverse voltage and 33 mA average rectified current, it fits signal-level rectification, clamping, and high-speed switching in harsh environments. The junction temperature range of -65°C to 150°C covers military and industrial thermal extremes. ## Low capacitance for RF and fast-switching circuits With 2 pF capacitance at 0 V bias (1 MHz), this diode introduces minimal parasitic loading in RF detector, mixer, and ESD protection circuits. The low capacitance preserves signal integrity at UHF frequencies and above, where a standard rectifier diode would roll off the bandwidth. Forward voltage is 1 V max at 15 mA, typical for a Schottky barrier at this current level. Reverse leakage is 200 nA at 50 V — low enough to avoid significant power loss in high-impedance bias networks. The UB package (3-SMD, No Lead) is a small surface-mount footprint suited for high-density PCB assembly. The base product number is 1N5711; the UBCA suffix denotes the specific package and screening level within the MIL-PRF-19500/444 family.","metaTitle":"1N5711UBCA Schottky Diode, 50V 33mA, MIL-PRF-19500/444","metaDescription":"Microchip Technology 1N5711UBCA Schottky diode, 50V reverse, 33mA average, 2pF capacitance.
