It is designed for high-speed switching and low forward voltage drop in signal-level rectification, clamping, and protection circuits. The 5 ns reverse recovery time and 7 pF junction capacitance at 1 V reverse bias make it a natural fit for RF detector stages, high-frequency DC-DC converter output rectification, and ESD clamp networks on data lines. ## 30 V reverse standoff and 200 mA forward current The 30 V maximum reverse voltage covers 5 V, 12 V, and 24 V rail protection without headroom concerns. The 200 mA average rectified current is the continuous load ceiling — derate above 85 °C junction temperature per the standard Schottky thermal profile. Forward voltage is specified at 1 V maximum at 200 mA, which sets the conduction loss floor for the application. Reverse leakage is 500 nA at 25 V reverse bias, rising with junction temperature — a consideration for battery-powered or high-temperature designs. ## Glass DO-213AA: hermetic seal for demanding environments The DO-213AA glass package is a hermetic, surface-mount barrel with metallised end caps — the Mini MELF. It offers superior moisture resistance compared to plastic SMD packages, making it a candidate for avionics, downhole instrumentation, and outdoor telecom modules where humidity or condensation is present. The junction temperature range spans -65°C to 125°C, covering military and industrial temperature grades. The glass body also provides good thermal cycling endurance for applications with wide ambient swings. ## Active lifecycle and compliance standing It is ROHS3 compliant, with no restricted substances above the threshold limits. For dual-sourcing resilience, the BAT43 series includes several pin-compatible glass and plastic SMD variants from multiple manufacturers. Qualifying an alternate now avoids a single-source lock-in if allocation shifts.","metaTitle":"TMMBAT43FILM Schottky Diode, 30 V, 200 mA, DO-213AA, Active","metaDescription":"STMicroelectronics TMMBAT43FILM Schottky diode, 30 V reverse, 200 mA average, 5 ns trr, DO-213AA glass package.
