BCP68T1

Overview

The onsemi BCP68T1G is a single NPN bipolar junction transistor (BJT) designed for medium-power applications. It features a maximum DC collector current of 1 A and a collector-emitter voltage rating of 20 V. The device utilizes a SOT-223 surface-mount package with four pins, offering a power dissipation capacity of 1.5 W. Key electrical characteristics include a collector-base voltage of 25 V, an emitter-base voltage of 5 V, and a minimum DC current gain (hFE) of 50. The transition frequency is specified at 60 MHz, with a collector-emitter saturation voltage of 500 mV. It operates within a temperature range of -65 °C to +150 °C.

Procurement Notes

Verify the exact part number suffix during procurement, as 'BCP68T1' may refer to the base series or require specific trailing characters like 'G' for RoHS compliance. Confirm package type and manufacturer documentation match requirements. Check datasheet revisions for parameter updates. Ensure sourcing channels provide authentic components from authorized distributors to avoid counterfeit risks. Validate compliance certifications if required for your specific application standards.

Selection Notes

Select this component when a single NPN transistor with 1 A continuous current and 20 V breakdown voltage is needed in a compact SOT-223 form factor. Consider the 60 MHz transition frequency for moderate-speed switching applications. Evaluate thermal management needs given the 1.5 W power dissipation limit. Compare hFE minimums against circuit gain requirements. Ensure the operating temperature range aligns with the system's environmental constraints.

Part Context

The BCP68T1G belongs to the BCP68 series of NPN medium-power transistors originally introduced by Philips Semiconductors and now manufactured by onsemi. This series is widely used in general-purpose electronic designs requiring reliable switching and amplification. The SOT-223 package provides a balance between power handling and board space efficiency, making it suitable for various commercial and industrial applications.
