BS170 Description

Short technical summary and product information.

The BS170 is an N-Channel enhancement mode MOSFET from On Semiconductor designed for low-power switching applications. It features a drain-source breakdown voltage of 60V minimum and 90V typical, with a continuous drain current rating of 300mA.

 

Key electrical characteristics include a maximum on-resistance of 5.0 Ohms at Vgs=10V and Id=200mA, gate threshold voltage range of 0.8V to 3.0V, and input capacitance of 60pF. The device offers fast switching with typical turn-on time of 5ns and turn-off time of 15ns.

 

The BS170 is packaged in a TO-92 through-hole package with formed leads, suitable for manual or automated assembly. It operates over a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 830mW.

 

This MOSFET is designed with high input impedance, CMOS logic compatible input, and no thermal runaway or secondary breakdown, making it suitable for interfacing with logic circuits and general-purpose switching.
