NCR421PAS-QX

Overview

The NCR421PAS-QX is an NPN bipolar junction transistor (BJT) manufactured by Nexperia, housed in a SOT-1118D (HUSON6) surface-mount package. It features a collector-emitter maximum voltage (VCEO) of 40 V and a continuous collector current of 250 mA. The device has a power dissipation rating of 530 mW and operates within a temperature range of -55 °C to +150 °C. Packaged in reels of 3000 units, it is designated as an automotive-grade component.

Feature Summary

Integrated constant-current source functionality for LED applications
Automotive qualification compliant with AEC-Q101 standards
Compact HUSON6 surface-mount packaging design

Applications

Automotive LED driver circuits
Constant-current LED regulation
General-purpose switching applications

Procurement Notes

Verify the specific suffix 'QX' against the manufacturer's official datasheet to confirm reel packaging specifications and exact automotive grade classification. Ensure the ordering part number matches the required tolerance and thermal characteristics defined in the latest Nexperia documentation before finalizing procurement orders.

Selection Notes

Select this component when designing automotive lighting systems requiring a compact, qualified NPN transistor solution. The HUSON6 package offers space efficiency compared to traditional leads. Confirm that the 40 V voltage rating and 250 mA current capacity align with the specific load requirements of the target LED circuit design.

Part Context

This component belongs to Nexperia’s portfolio of automotive-qualified discrete semiconductors. It is part of a series designed to meet the rigorous reliability standards required for modern vehicle electronics. The product line emphasizes robust performance in demanding thermal and electrical environments typical of automotive under-hood or exterior lighting modules.

Replacement Considerations

Check for direct substitutes such as the NCR420PAS-QX, which shares similar packaging but may differ in current ratings. Verify pinout compatibility and electrical parameters against the original design specifications before substituting any alternative components from other manufacturers.
