NSBC143TDXV6T5

Overview

The NSBC143TDXV6T5 is a dual digital transistor from onsemi, configured as two NPN transistors in a single SOT-563-6 package. It features built-in bias resistors with a typical value of 4.7 kOhms and a resistor ratio of 1. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 357 mW. The unit operates within a temperature range of -55°C to +150°C and has a minimum DC current gain (hfe) of 160.

Feature Summary

• Integrates dual NPN transistors with pre-biased resistors for simplified circuit design.
• Utilizes compact SOT-563-6 surface-mount packaging for space-constrained applications.
• Provides high thermal stability with an extended operating temperature range up to 150°C.

Applications

• General-purpose switching circuits requiring dual NPN logic interfaces.
• Driver stages for low-current loads in consumer electronics.
• Level shifting or buffer applications in embedded systems.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets, as legacy variants may differ. Check for End-of-Life (EOL) notices or Production Change Notifications (PCN) to assess long-term availability and potential supply chain disruptions before finalizing procurement plans.

Selection Notes

Select this component when a dual NPN configuration with integrated base resistors is required. Ensure the 50V voltage rating and 100mA current capacity meet the load requirements. Verify that the 4.7kOhm input resistance aligns with the driving source capabilities. Consider the SOT-563-6 footprint constraints during PCB layout design.

Part Context

This part belongs to the NSBC143 series of digital transistors by onsemi. It shares the same internal transistor structure and electrical characteristics as the NSBC143EPDXV6T1G but differs in packaging and specific ordering suffixes. It is distinct from complementary pairs like the NSBC114 series, which combine NPN and PNP types.

Replacement Considerations

Direct substitutes include NSBC143EPDXV6T1G, which offers identical electrical performance. Other compatible options may include NSBA143TDXV6T5 if PNP polarity is acceptable, though functional equivalence requires careful verification of transistor type and pinout compatibility.
