Device identity and key parametrics
The BAS70JFILM is a small-signal Schottky diode from STMicroelectronics, housed in a SOD-323 surface-mount package. It is rated for 70 V reverse voltage and 70 mA average rectified current, with a forward voltage of 1 V max at 15 mA. The diode's junction capacitance is 2 pF at 0 V and 1 MHz, making it suitable for high-speed switching applications where low capacitive loading matters. Reverse leakage is 10 µA at 70 V. The junction temperature rating is 150°C max, and the device is classified as Small Signal =< 200mA (Io), Any Speed, covering general-purpose low-current rectification and clamping.
It is RoHS3 compliant, meeting current environmental requirements for lead-free assembly. The base product number is BAS70, and the suffix J indicates the SOD-323 package variant. The FILM suffix denotes tape-and-reel packaging for automated pick-and-place.
