NSBC143ZDXV6T5G

Overview

The NSBC143ZDXV6T5G is a dual NPN bipolar digital transistor (BRT) manufactured by onsemi, housed in an SOT-563-6 surface-mount package. It integrates two NPN transistors with typical base resistors of 4.7 kOhms and a resistor ratio of 0.1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of 50 V, continuous collector current of 100 mA, and minimum DC current gain (hFE) of 80. The device operates within a temperature range of -55°C to +150°C and features a power dissipation rating of 357 mW.

Feature Summary

• Integrates dual NPN transistors with built-in biasing resistors for simplified circuit design
• Optimized for high-speed switching applications through integrated pre-biasing
• Compact SOT-563-6 packaging suitable for space-constrained surface-mount layouts

Applications

• General-purpose switching circuits requiring dual NPN logic interfaces
• Driver stages for relays, solenoids, or small loads in consumer electronics
• Level shifting and signal buffering in embedded systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for end-of-life notices or production change notifications prior to procurement. Ensure storage conditions meet semiconductor handling standards to prevent moisture sensitivity issues.

Selection Notes

Select this component when dual NPN switching with integrated base resistors is required. Verify that the 50 V voltage rating and 100 mA current capacity align with load requirements. Consider the SOT-563-6 footprint constraints during PCB layout. Compare thermal performance against system power dissipation limits.

Part Context

This part belongs to onsemi's NSBC series of dual digital transistors. It shares the SOT-563-6 package form factor with other variants in the family but differs in internal resistor values and transistor polarity configurations. The ZD suffix typically denotes specific resistor tolerance or configuration characteristics within the product line.

Replacement Considerations

NSBA143ZDXV6T1G offers identical packaging and similar electrical characteristics but utilizes PNP transistors instead of NPN. Verify polarity requirements before substitution. Other NSBC series variants may provide different resistor ratios or gain specifications.
