Single Bipolar Transistors datasheet and documents for BC337-40

BC337-40

Single Bipolar Transistors Overview

The Diotec Semiconductor BC337-40 is a general-purpose NPN silicon epitaxial planar transistor designed for switching and amplifier applications. It features a collector-emitter voltage (VCEO) of 45 V, a maximum DC collector current (IC) of 800 mA, and a peak collector current (ICM) of 1 A. The device has a power dissipation rating of 625 mW at 25°C ambient temperature and operates within a junction temperature range of -55°C to +150°C. As part of the -40 gain group, it provides a minimum DC current gain (hFE) of 250 at IC = 100 mA and VCE = 1 V, with a typical transition frequency (fT) of 100 MHz.

Single Bipolar Transistors Feature Summary

Three distinct DC current gain groups (-16, -25, -40) allow for precise selection based on amplification requirements.
Compliant with RoHS directives without exemptions, REACH regulations, and conflict minerals standards.
Offers low collector-emitter saturation voltage and high collector current capability suitable for driver stages.
Compatible with standard through-hole assembly processes and available in compact TO-92 packaging.

Single Bipolar Transistors Applications

Signal processing circuits
General purpose switching applications
Audio frequency amplification

Single Bipolar Transistors Procurement Notes

Verify that the specific ordering suffix matches the required gain group and compliance level. Confirm package type and tape/reel specifications against manufacturing requirements. Ensure design parameters remain within absolute maximum ratings to maintain reliability. Check for automotive-grade variants if AEC-Q101 qualification is necessary for the target application environment.

Single Bipolar Transistors Selection Notes

Select the BC337-40 variant when a higher minimum DC current gain is required compared to the -16 or -25 groups. Consider the thermal resistance and power dissipation limits relative to the expected ambient operating conditions. Evaluate the complementary BC327/BC328 PNP transistors if push-pull configurations are needed. Verify that the 45 V collector-emitter breakdown voltage meets the circuit's maximum voltage stress requirements.

Single Bipolar Transistors Part Context

The BC337 series belongs to a family of universal NPN transistors widely used in commercial and industrial electronics. It serves as a standard component for low-power signal handling and switching tasks. The device is often paired with its PNP counterpart, the BC327, to form complementary pairs in various analog and digital circuit topologies.
