BC368

Single Bipolar Transistors Overview

The BC368 is an NPN silicon amplifier transistor manufactured by onsemi, designed for general-purpose small-signal applications. It operates within a collector-emitter voltage range of up to 20 Vdc and supports continuous collector currents of 1.0 Adc. The device features a DC current gain (hFE) ranging from 50 to 375 depending on the specific sub-series variant and operating conditions. Electrical characteristics include a bandwidth product of 65 MHz at 10 mA and a maximum junction temperature of +150°C. Thermal resistance values are specified as 200 °C/W junction-to-ambient and 83.3 °C/W junction-to-case.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix when purchasing, as it determines packaging format such as bulk boxes or ammo boxes. Confirm lead-free status if required by assembly specifications. Ensure the selected variant matches the necessary hFE binning for the intended circuit performance. Cross-reference datasheet revision numbers to guarantee compatibility with design parameters.

Single Bipolar Transistors Selection Notes

Select the BC368 based on required current gain bins and thermal management needs. Evaluate the package style against available board space and mounting constraints. Consider the BC369 PNP counterpart for complementary push-pull configurations. Verify that the application voltage does not exceed the 20 Vdc collector-emitter rating under all operating conditions.

Single Bipolar Transistors Part Context

The BC368 belongs to a family of small-signal transistors alongside the BC369 PNP version. These components are widely utilized in consumer electronics and industrial control systems where reliable switching and amplification are required. The TO-92 package provides a compact solution for through-hole mounting in standard printed circuit board layouts.

Single Bipolar Transistors Replacement Considerations

The BC369 serves as the direct PNP complement within the same series. Other generic NPN transistors with similar voltage and current ratings may function as substitutes if electrical characteristics align closely with the original design requirements.
