NSBC124EMXWTBG

Overview

The NSBC124EMXWTBG is a single NPN digital bias resistor transistor (NBRT) from the NSBCMXW series, manufactured by onsemi. It integrates an NPN transistor with internal biasing resistors in a compact XDFNW3 package. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 10 kOhms with a resistor ratio of 1. It offers a minimum DC current gain (hFE) of 35 at 5 mA and 10 V. Power dissipation is rated at 450 mW, with an operating temperature range spanning from -65°C to +150°C.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status through the latest datasheet before integration. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Selection Notes

Select this component when space constraints require combining a transistor and bias resistors. Ensure the required input resistance matches the 10 kOhm specification. Verify that the 50 V voltage rating and 100 mA current capacity meet the circuit requirements. Consider the XDFNW3 package dimensions for PCB layout compatibility.

Part Context
