The forward voltage drops to 450 mV typical at 1 mA forward current, and junction capacitance is just 2 pF at 1 V reverse bias — numbers that place it squarely in the signal-level switching and clamping class, not power rectification. ## Hermetic seal and temperature reach The DO-213AA glass package is a hermetic enclosure — no epoxy, no moisture ingress path. For designs that see condensation, potting cycles, or vacuum environments, this matters more than the electrical ratings. Junction temperature range spans -65°C to 125°C, covering military cold-soak and under-hood hot-soak equally. Reverse leakage at 50 V is held to 100 nA typical — a tight number that holds up across the temperature sweep because the glass package keeps the die dry. ## BOM-fit check: low-current clamping and detection At 100 mA average current, this diode is sized for signal conditioning, not bulk power. Typical roles: input protection clamp on a 24 V industrial sensor line, flyback catch on a relay coil under 100 mA, or reverse-polarity blocking on a low-power rail where the 450 mV drop at 1 mA beats a standard pn-junction's 700 mV. The 2 pF junction capacitance keeps the diode transparent in RF detector circuits up to low UHF — a Schottky with 1 pF to 2 pF is the usual choice for zero-bias envelope detection around 100 MHz. ## Active and compliant ROHS3 compliance is confirmed — no exemptions that would trip a 2025 EU or UKCA declaration.","metaTitle":"STMicroelectronics TMMBAT41FILM Schottky Diode, 100 V","metaDescription":"ST TMMBAT41FILM Schottky diode: 100 V reverse, 100 mA average, 450 mV Vf at 1 mA, 2 pF capacitance.
