BC33740TA

Single Bipolar Transistors Overview

The onsemi BC33740TA is an NPN silicon epitaxial planar transistor designed for switching and audio frequency amplifier applications. It features a maximum DC collector current of 800 mA, a collector-emitter voltage (VCEO) of 45 V, and a collector-base voltage (VCBO) of 50 V. The device operates within a junction temperature range of -55°C to +150°C and dissipates up to 625 mW. It offers a minimum DC current gain (hFE) of 60 and a transition frequency (fT) of 100 MHz. Packaged in a lead-free TO-92 three-pin through-hole housing, it ensures reliable performance in general-purpose circuits.

Single Bipolar Transistors Procurement Notes

Verify the specific suffix TA against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component meets the required environmental standards, such as halogen-free and lead-free specifications, by checking the marking code or documentation provided by the authorized distributor. Cross-reference the part number with the latest onsemi product change notices to confirm manufacturing status and availability.

Single Bipolar Transistors Selection Notes

Select this component when a medium-power NPN transistor with high current gain is required for low-frequency amplification or switching tasks. The BC33740TA variant provides a specific hFE binning suitable for applications demanding consistent gain characteristics. Consider the thermal resistance and power dissipation limits relative to the ambient operating conditions and PCB layout constraints to ensure stable operation without exceeding the maximum junction temperature rating.

Single Bipolar Transistors Part Context

This device belongs to the BC337 series of NPN transistors manufactured by onsemi. The series includes variants differentiated by their DC current gain ranges, such as the BC337-16, BC337-25, and BC337-40. The BC33740TA specifically denotes the -40 gain group packaged in a tape-and-reel format. It serves as a complementary counterpart to the PNP BC327 series, facilitating push-pull and differential amplifier designs in consumer and industrial electronics.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC33740BU for bulk packaging or other manufacturers' BC337-40 equivalents with matching electrical ratings.
