Product details

Package and mounting

The TMMBAT42FILM is a small-signal Schottky diode from STMicroelectronics, rated for 30 V DC reverse voltage and 200 mA average rectified current. The Schottky barrier gives it a forward voltage drop of 1 V max at 200 mA and a reverse recovery time of 5 ns — no stored charge to sweep out, so it switches cleanly in high-frequency rectifier and snubber circuits.

Package and rework — DO-213AA glass Mini MELF

Housed in a glass Mini MELF package — surface-mount with metallised end caps. The glass body is hermetic.

Temperature range and operating envelope

Junction temperature range spans -65 to 125 °C, which covers most industrial and some automotive under-hood environments. The reverse leakage at 25 V is 500 nA typ — expect that to rise with temperature, but the Schottky construction keeps it manageable up to the 125 °C ceiling.

Lifecycle status is Active, with ROHS3 compliance.
