MMBF4392LT1G Description

Short technical summary and product information.

The MMBF4392LT1G is an N-Channel JFET switching transistor manufactured by ON Semiconductor. This device is designed for switching applications and operates with a maximum drain-source voltage of 30V.

 

Key electrical characteristics include a zero-gate-voltage drain current (IDSS) typically 25mA at 15V, and a drain-source on-voltage (VDS(on)) of 0.4V maximum at 3.0mA. The static drain-source on-resistance (rDS(on)) is specified at 60 Ohms. It also features an input capacitance (Ciss) of 14pF and a reverse transfer capacitance (Crss) of 3.5pF.

 

This JFET is housed in a compact SOT-23-3 (TO-236) surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -55°C to 150°C.

 

The MMBF4392LT1G is Pb-Free and Halogen Free, complying with RoHS standards. Its S prefix indicates suitability for automotive applications requiring unique site and control change requirements, and it is AEC-Q101 qualified and PPAP capable.
