BC328-40

Single Bipolar Transistors Overview

The Diotec Semiconductor BC328-40 is a general-purpose PNP bipolar junction transistor (BJT) housed in a TO-92 package. It features a maximum collector current of 800 mA and a peak collector current of 1 A. The device has a collector-emitter voltage rating of -25 V with the base open, or -30 V with the emitter-base shorted. Power dissipation is rated at 625 mW. The component operates within a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify that the specific part number suffix matches the required reliability grade. Standard commercial/industrial versions lack automotive certification. Only parts explicitly marked with the -Q or -AQ suffixes are compliant or qualified under the AEC-Q101 standard. Confirm the package type and lead configuration before ordering.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with an 800 mA continuous collector current capability is required. Ensure the design accounts for the -25 V collector-emitter voltage limit. Choose the appropriate current gain group (-16, -25, or -40) based on the necessary hFE specifications for the intended application.

Single Bipolar Transistors Part Context

This component belongs to the BC327...BC328 series of universal PNP transistors manufactured by Diotec Semiconductor. It serves as the complementary counterpart to the BC337...BC338 NPN transistor series. The product line includes variants with different voltage ratings and current gain groupings to support diverse electronic design requirements.

Single Bipolar Transistors FAQ

What is the maximum collector-emitter voltage for the BC328-40?

The maximum collector-emitter voltage (VCEO) is -25 V when the base is open, and -30 V when the emitter-base is shorted.

Does the standard BC328-40 meet automotive standards?

No. Only versions with the -Q (compliant) or -AQ (qualified) suffixes meet the AEC-Q101 automotive standards.

How many current gain groups are available for this transistor?

There are three current gain groups available: Group -16, Group -25, and Group -40.
