BC337-40BK

Single Bipolar Transistors Overview

The Diotec Semiconductor BC337-40BK is an NPN general-purpose silicon epitaxial planar transistor housed in a TO-92 plastic case. It features a maximum collector-emitter voltage (VCEO) of 45 V and a continuous collector current (IC) of 800 mA. The device belongs to the -40 gain group, providing a DC current gain (hFE) range of 250 to 630 at IC = 100 mA and VCE = 1 V. Power dissipation is rated at 625 mW, with a junction temperature range of -55°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix BK against official Diotec documentation to confirm bulk packaging specifications. Ensure the selected part number matches the required hFE gain group (-40) for your circuit design. Cross-reference the datasheet version date to confirm all electrical characteristics remain consistent with your design requirements.

Single Bipolar Transistors Selection Notes

Select this component when a high-gain NPN transistor is required for standard commercial or industrial applications. The -40 designation ensures a minimum hFE of 250, making it ideal for sensitive amplifier designs. Consider the complementary BC327/BC328 PNP transistors if push-pull configurations are needed.

Single Bipolar Transistors Part Context

This transistor is part of the BC337-xBK series, which includes variants with different gain groups (-16, -25, -40). The BC337 series is widely used as a general-purpose NPN transistor. The -BK suffix typically denotes special bulk packaging options provided by Diotec Semiconductor.

Single Bipolar Transistors Replacement Considerations

Direct parameter-equivalent replacements include other manufacturers' BC337-40 variants. For complementary PNP operation, consider the BC327 series.
