It handles a maximum forward current of 110 mA and a peak reverse voltage of 4V — low enough that you are working with small-signal RF paths, not power rectification. Junction capacitance is just 0.5 pF at zero bias, which keeps the diode transparent at UHF and low microwave frequencies. Series resistance measures 5.5 Ω at 50 mA and 1 MHz, a figure that directly affects conversion loss when the diode is used as a mixer element. ## What the key ratings mean for your RF front-end The 0.5 pF capacitance at 0V reverse bias is the headline spec here. In a detector circuit, that capacitance forms a low-pass corner with the source impedance — too high and you roll off the modulation bandwidth. At 4V peak reverse, the diode is meant for signal levels typical of an antenna input or a local-oscillator injection, not for high-swing stages. The 5.5 Ω series resistance at 50 mA tells you the on-resistance under typical RF drive; lower resistance means less signal loss in the mixing process. Maximum junction temperature is 150°C, so the part can sit near a warm RF amplifier without derating concerns. That makes it safe to qualify into a new BOM or to replenish an existing production line without worrying about a sudden discontinuation.","metaTitle":"BAT15-05WH6327XTSA1 Schottky Diode, 110 mA, 4V, SOT-323","metaDescription":"Infineon BAT15-05WH6327XTSA1 RF mixer/detector Schottky diode, 110 mA max, 4V peak reverse, 0.5 pF capacitance.
