BCV46TA

Overview

The BCV46TA is a PNP Darlington transistor manufactured by Diodes Incorporated, housed in an SOT-23-3 surface-mount package. It features a maximum collector-emitter voltage of 60 V and a continuous collector current rating of 500 mA. The device offers a transition frequency of 200 MHz and a maximum power dissipation of 330 mW. DC current gain (hFE) is specified at a minimum of 10,000 when tested at 100 mA and 5 V. The saturation voltage is limited to 1 V under conditions of 100 µA base current and 100 mA collector current. Operating junction temperature ranges from -55°C to 150°C.

Feature Summary

• High DC current gain characteristic typical of Darlington configurations
• Compact SOT-23-3 surface-mount footprint for space-constrained designs
• Capable of handling moderate collector currents up to 500 mA

Applications

• General-purpose switching applications
• Driver circuits requiring high input impedance
• Low-voltage signal processing stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure that the procurement channel provides traceability documentation consistent with RoHS3 and REACH regulatory requirements. Confirm that the component status remains active before finalizing supply agreements.

Selection Notes

Select this component when a PNP Darlington configuration is required within a small SOT-23-3 package. The high current gain reduces base drive requirements compared to standard bipolar transistors. Evaluate thermal management needs given the 330 mW power dissipation limit in the specified package type.

Part Context

This part belongs to the BCV46 series of PNP Darlington transistors produced by Diodes Incorporated. The series is designed for general-purpose amplification and switching tasks where high gain and compact packaging are prioritized. The TA suffix typically denotes specific tape-and-reel packaging configurations used in automated assembly processes.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include BCV46-W, BCV46E6327HTSA1, and 2SB852KT146B. Verify pinout alignment and electrical specifications against original design requirements before substitution.
