NSVBC144EMXWTBG

Overview

The NSVBC144EMXWTBG is a single NPN digital transistor from the onsemi NSBCMXW series, housed in an XDFNW3 package. It integrates a built-in base resistor with a typical value of 2.2 kOhms and a typical resistance ratio of 0.1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 80 at 5 mA and 10 V, and a power dissipation rating of 450 mW. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Integrates a single NPN transistor with a fixed base resistor for simplified circuit design
• Optimized for high-speed switching applications with low input capacitance
• Designed for surface-mount assembly using compact XDFNW3 packaging

Applications

• General-purpose switching circuits
• Driver stages for logic-to-power interface
• Level shifting between different voltage domains

Procurement Notes

Verify the specific suffix MXWTBG against official datasheets to confirm the exact reel quantity and tape-and-reel specifications. Ensure that the ordering information matches the required RoHS compliance status and lead-free manufacturing standards defined by the manufacturer for this specific batch code.

Selection Notes

Select this component when a single NPN configuration with a 2.2 kOhm base resistor is required. Compare the 50 V breakdown voltage and 100 mA current limits against load requirements. Consider the XDFNW3 footprint constraints and thermal dissipation capabilities relative to the available PCB copper area for heat spreading.

Part Context

This part belongs to the NSBCMXW family of digital transistors, which are designed to replace multiple discrete components. It serves as a drop-in replacement for standard BRTs in space-constrained designs. The series offers various resistor values and configurations to accommodate different logic families and drive requirements.

Replacement Considerations

Check for direct pin-compatible alternatives within the same NSBCMXW series or other manufacturers' single NPN BRTs with identical 2.2 kOhm base resistance and 50 V ratings. Verify that the replacement maintains the same hFE minimum and package dimensions.
