BSS139 Description

Short technical summary and product information.

The Infineon BSS139 is a SIPMOS Small-Signal-Transistor featuring N-channel depletion mode operation. It is designed for applications requiring a breakdown voltage of up to 250V.

 

Key electrical characteristics include a gate threshold voltage typically around -1.4V and a maximum on-state resistance of 30 Ohms at VGS=0V and ID=15mA. The device also offers a typical on-state resistance of 7.8 Ohms at VGS=10V and ID=0.1mA. Dynamic characteristics such as input capacitance (Ciss) are typically 7.6pF, output capacitance (Coss) at 8.4pF, and reverse transfer capacitance (Crss) at 3.3pF.

 

Packaged in a PG-SOT-23, the BSS139 is suitable for surface-mount designs. It operates within a temperature range of -55°C to 150°C and has a power dissipation of 0.36W at 25°C ambient temperature. The device is Pb-free and RoHS compliant.

 

This MOSFET is well-suited for general-purpose switching and amplification tasks in various electronic circuits where a depletion-mode device is preferred.
