MMBF5459 Description

Short technical summary and product information.

The MMBF5459 is an N-Channel JFET transistor manufactured by On Semiconductor, suitable for low-level audio amplification and analog switching applications. It is sourced from Process 55 and offers a drain-gate voltage of 25V and a gate-source voltage of -25V.

 

Key electrical characteristics include a zero-gate voltage drain current (IDSS) of 4 mA @ 15V and a gate-source cutoff voltage (VGS(off)) of -2V @ 10 nA. The forward transfer conductance (gfs) is typically 2000 µmhos, and the input capacitance (Ciss) is a maximum of 7 pF @ 15V.

 

This JFET is designed for surface mounting and comes in a TO-236-3, SC-59, or SOT-23-3 package. It operates within a temperature range of -55°C to +150°C (TJ) and has a maximum power dissipation of 350 mW. The device is RoHS3 compliant.
