Single FETs, MOSFETs datasheet and documents for BS270
Single FETs, MOSFETs Overview
The BS270 is a small-signal N-channel enhancement-mode MOSFET manufactured by ON Semiconductor. It features a TO-92 or TO-226-3 leaded package designed for low-power switching applications. Key electrical parameters include a drain-source voltage (Vds) of 60 V, a continuous drain current (Id) of 500 mA, and a maximum gate-source voltage (Vgs) of ±20 V. The device exhibits a typical on-resistance (Rds(on)) of 5 Ω at a gate drive of 10 V. Thermal characteristics specify a maximum junction temperature range from -55 °C to 150 °C with a power dissipation rating of 350 mW.
Single FETs, MOSFETs Feature Summary
- N-channel enhancement mode operation for standard logic-level switching
- Leaded plastic package suitable for through-hole mounting
- Defined thermal operating limits for reliable performance
Single FETs, MOSFETs Applications
- Low-current DC load switching
- General-purpose signal isolation
- Small-signal amplification circuits
Single FETs, MOSFETs Procurement Notes
Verify the specific manufacturer marking and package variant during acquisition, as legacy components may originate from multiple production sources including Fairchild Semiconductor or ON Semiconductor. Confirm that the received units match the required pinout configuration for the intended PCB footprint. Ensure compliance with RoHS standards if applicable to the final assembly requirements.
Single FETs, MOSFETs Selection Notes
Select this component when a low-cost, through-hole N-channel MOSFET is required for currents up to 500 mA. The relatively high on-resistance makes it unsuitable for high-efficiency power conversion but appropriate for low-power control tasks. Evaluate the thermal constraints carefully due to the limited power dissipation capability inherent in the small leaded package.
Single FETs, MOSFETs Part Context
This part belongs to the family of general-purpose small-signal MOSFETs used in consumer electronics and industrial control boards. Historically produced by Fairchild Semiconductor before corporate acquisitions, it remains a standard reference for basic discrete transistor switching needs where surface-mount options are not mandated.
