BC337,112

Single Bipolar Transistors Overview

The BC337,112 is an NPN general-purpose silicon transistor manufactured by Nexperia (formerly NXP Standard Products). It utilizes a SOT54 plastic single-ended leaded through-hole package. The device supports a maximum collector current of 500 mA and a collector-emitter voltage of 45 V. Peak collector current reaches 1 A. DC current gain ranges from 100 to 600 at IC = 100 mA. Total power dissipation is 625 mW at 25 °C ambient temperature.

Single Bipolar Transistors Feature Summary

Single Bipolar Transistors Procurement Notes

Verify the manufacturer origin carefully, as the former NXP Standard Product business was rebranded to Nexperia in February 2017. Ensure the ordering code matches the specific suffix requirements for the desired packing method, such as bulk or tape and reel options available for the SOT54 package variant.

Single Bipolar Transistors Selection Notes

Select this component when a robust NPN transistor with moderate current handling is required for through-hole assembly. Consider the specific hFE binning if precise gain control is necessary, as the standard version covers a wide gain range. Verify thermal management requirements against the junction-to-ambient thermal resistance specifications provided in the datasheet.

Single Bipolar Transistors Part Context

This part belongs to the BC817/BC337 family of NPN general-purpose transistors. It serves as the through-hole equivalent to surface-mount variants like the BC817. The PNP complement for this device is the BC327. The product line includes various selection groups differentiated primarily by their DC current gain characteristics.

Single Bipolar Transistors FAQ

What is the pin configuration for the SOT54 package?

Pin 1 is the emitter, Pin 2 is the base, and Pin 3 is the collector.

Does the ordering suffix change the electrical function?

No, the suffix indicates manufacturing location or packing method. Electrical parameters remain consistent within the specified limits for the base type number.
