SLA6012

Overview

The SLA6012 is a PNP + NPN Darlington integrated circuit designed for three-phase motor drive applications. It features an internal equivalent circuit with specific resistor values: R1 at 3kΩ, R2 at 2kΩ, and R3 at 150Ω. The device supports continuous collector currents of ±4A and offers a maximum power dissipation of 5W at 25°C ambient temperature or 25W at 25°C case temperature. Key electrical ratings include a collector-emitter voltage (VCEO) of ±60V, a base current capability of ±0.5A, and a junction temperature range up to 150°C. The component provides high current gain (hFE) of 2000 under standard test conditions.

Feature Summary

• Integrated PNP and NPN Darlington pairs optimized for three-phase motor control
• High current handling capability with ±4A continuous collector current rating
• Internal biasing resistors simplify external circuit design
• Robust thermal performance with low thermal resistance from junction to case

Applications

• Three-phase motor drive systems
• Industrial motor control circuits
• Power switching applications requiring high current gain

Procurement Notes

Verify the component status as "Not Recommended for New Designs" before initiating procurement. Ensure that existing inventory meets long-term supply requirements for maintenance or replacement purposes. Confirm package compatibility and thermal management specifications align with the target application's cooling infrastructure. Review datasheet revisions for any updates to absolute maximum ratings.

Selection Notes

Select this component only for legacy designs or direct replacements where the specific pinout and internal resistor configuration are required. Evaluate thermal constraints carefully, as power dissipation drops significantly without a heatsink. Consider alternative modern drivers if new design space allows, given the obsolescence status. Verify that the ±60V voltage rating suits the system's operating voltage levels.

Part Context

The SLA6012 belongs to Sanken Electric's series of Darlington transistor arrays intended for motor driving. It integrates multiple transistors and resistors into a single 12-pin package to reduce board space and component count. This integration simplifies the design of three-phase bridge circuits by providing matched transistor characteristics and built-in biasing networks.
