Overview
The NCR402UH is a linear LED driver IC manufactured by Nexperia, designed for constant current applications. It features an integrated PNP transistor with two diodes on a single chip, housed in an SOT-457 (SC-74) plastic package. The device provides a stabilized output current of 20 mA with high accuracy across supply voltage variations. It operates within a supply voltage range up to 18 V and delivers an output voltage of 16 V. The component supports a maximum power dissipation of 750 mW and functions reliably within a temperature range of -55°C to 150°C.
Feature Summary
- Integrates a resistor-equipped PNP transistor with two diodes on one chip to reduce component count and board space
- Provides stabilized output current with high accuracy despite supply voltage variations
- Features low voltage overhead of 1.4 V for efficient operation
- Qualified according to AEC-Q101 standards for automotive reliability
Applications
- Constant current LED driver circuits
- Generic constant current source implementations
- Automotive lighting applications
Procurement Notes
Verify the specific suffix 'H' against official Nexperia documentation to confirm tape and reel specifications or marking details. Ensure compatibility with SOT-457 footprint requirements during PCB layout. Confirm that the AEC-Q101 qualification meets specific automotive project standards before finalizing procurement decisions.
Selection Notes
Select this component when a compact, linear solution for low-current LED driving is required. The integrated design simplifies bill of materials compared to discrete solutions. Consider the 1.4 V overhead and 750 mW power dissipation limits for thermal management. Verify that the 20 mA fixed current aligns with target LED specifications or allows for external adjustment if higher currents are needed.
Part Context
The NCR402U series belongs to Nexperia's portfolio of essential semiconductors for automotive and industrial applications. As part of the PSSI2021SAY family, these drivers offer reliable performance in harsh environments. The SOT-457 package provides a small form factor suitable for space-constrained designs. This product line supports Nexperia's commitment to efficiency and quality in electronic design.
