Overview
The SLA4052 is an NPN Darlington transistor array with a built-in freewheeling diode, housed in a SIP 21 package with a fin. It integrates nine elements to provide high DC current gain and robust switching capabilities. Key electrical parameters include a collector-emitter voltage (VCEO) of 120 V, a continuous collector current (IC(DC)) of 3 A, and a typical saturation voltage (VCE(sat)) of 1.1 V at 1.5 A. The device features a typical DC current transfer ratio (hFE) of 5000. Maximum allowable power dissipation is 5 W at ambient temperature or 25 W at case temperature.
Feature Summary
- Integrates nine NPN Darlington transistor elements within a single package for compact circuit design.
- Includes built-in freewheeling diodes to manage inductive load flyback currents effectively.
- Provides high DC current gain suitable for direct driving of high-current loads without intermediate amplification.
Applications
- Relay driver circuits
- Solenoid driver applications
- Lamp driver systems
- LED drive configurations
Procurement Notes
Verify the specific datasheet revision and manufacturer documentation before integration. Confirm that the SIP 21 package dimensions and thermal requirements align with the target PCB layout and heatsinking strategy. Ensure operating conditions remain within the specified absolute maximum ratings to maintain device reliability and prevent premature failure.
Selection Notes
Select this component when high current switching capability is required alongside integrated protection for inductive loads. The high current gain reduces base drive requirements, simplifying control logic interfacing. Consider the thermal management needs associated with the SIP 21 package and fin structure for effective heat dissipation during continuous operation.
Part Context
This component belongs to Sanken Electric's lineup of power transistor arrays designed for industrial and consumer electronic applications. It serves as a robust solution for driving heavy loads where multiple channels are needed. The inclusion of freewheeling diodes distinguishes it from standard transistor arrays, offering enhanced functionality for inductive load management.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify pin compatibility and electrical specifications if considering alternative manufacturers' Darlington arrays with similar voltage and current ratings.
