BC238BU

Single Bipolar Transistors Overview

The BC238BU is a single NPN epitaxial planar silicon transistor manufactured by onsemi. It operates with a maximum collector-emitter voltage of 25 V and a continuous collector current of 100 mA. The device features a transition frequency of 250 MHz and a maximum power dissipation of 500 mW. DC current gain (hFE) is specified at a minimum of 120 under test conditions of 2 mA collector current and 5 V collector-emitter voltage. The saturation voltage is limited to 600 mV at 100 mA collector current. It utilizes a TO-92-3 through-hole package and supports junction temperatures up to 150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix against official manufacturer documentation, as ordering codes may indicate variations in packaging or compliance status. Confirm component availability status directly with authorized distributors, as this part number may be subject to discontinuation notices. Ensure that any substitute components meet identical electrical specifications and physical footprint requirements for direct replacement in existing designs.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage NPN transistor with moderate current handling and high-frequency response is required. The TO-92-3 package facilitates easy integration into through-hole PCB layouts. Consider the 25 V breakdown limit and 100 mA current rating to ensure operation remains within absolute maximum ratings during peak signal swings or transient conditions.

Single Bipolar Transistors Part Context

The BC238BU belongs to the BC237/238/239 series of NPN transistors produced by onsemi. This family is designed for general-purpose use, offering consistent performance across varying manufacturing batches. The BU suffix typically denotes specific binning or packaging configurations within the broader BC238 product line, adhering to standard industry pinouts for TO-92 packages.
