Overview
The ZXTD4591AM832TA is a complementary dual transistor from Diodes Incorporated, packaged in the 3mm x 2mm MLP (Micro Leaded Package). It integrates an NPN and PNP transistor within a single surface-mount device. The NPN transistor provides a continuous collector current of 2.5A with a maximum collector-emitter voltage of 40V. The PNP transistor supports a continuous collector current of 2.0A with a maximum collector-emitter voltage of -40V. Both transistors feature a transition frequency of 150MHz. The package dimensions are 3.00mm by 2.00mm with a nominal height of 0.9mm.
Feature Summary
- Low saturation voltage for improved circuit efficiency
- High current gain specified up to 2A
- Miniature footprint reducing PCB area and component count
Applications
- DC-DC Converters
- Power switches
- Motor control
- LED Backlighting circuits
Procurement Notes
Verify the obsolete status before procurement. Confirm if the recommended replacement part number meets all design requirements. Check authorized distributor availability as standard stock may be limited due to discontinuation.
Selection Notes
Evaluate thermal resistance under specific PCB copper layout conditions. Ensure the required continuous collector current does not exceed the absolute maximum ratings for both NPN and PNP channels. Consider the MLP package size constraints during board layout.
Part Context
This component belongs to the MPPS Miniature Package Power Solutions series. It is designed to replace larger packages while maintaining equivalent performance capabilities. The integration of complementary transistors aids in power management functions.
