SLA5074

Overview

The SLA5074 is a N-channel power MOSFET manufactured by Sanken Electric USA Inc., designed for 5-phase motor drive applications. It features a drain-source voltage rating of 60 V and a continuous drain current of 5 A, with a pulsed current capacity of 8 A under specified conditions. The device utilizes a 15-pin SLA package with an integrated heatsink fin. Key electrical characteristics include a maximum on-resistance of 0.3 Ω at VGS=4V and ID=3A, and a threshold voltage ranging from 1.0 V to 2.0 V. Thermal performance is defined by a junction-to-air thermal resistance of 26 °C/W without a heatsink.

Feature Summary

• Integrated heatsink fin structure for efficient thermal dissipation in the 15-pin SLA package
• Optimized for driving 5-phase brushless DC motors with high transconductance
• Low on-state resistance to minimize conduction losses during operation

Applications

• 5-phase brushless DC (BLDC) motor drives
• High-efficiency motor control systems requiring low conduction loss
• Industrial automation equipment utilizing multi-phase motor architectures

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and packaging configuration. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing 5-phase motor drivers requiring a 60 V rating and up to 5 A continuous current. Ensure the PCB layout accommodates the 15-pin SLA package dimensions and provides adequate copper area for thermal management. Evaluate the thermal resistance constraints based on whether a heatsink is utilized, as the junction-to-air resistance differs significantly between mounted and unmounted states.

Part Context

This component belongs to Sanken Electric's specialized series of power MOSFETs tailored for multi-phase motor control. Unlike standard discrete MOSFETs, the SLA5074 integrates a dedicated heatsink fin within its lead frame design. This structural feature distinguishes it from general-purpose switching devices, optimizing it specifically for the thermal and spatial demands of 5-phase BLDC motor applications.
