STK551-3A0A-E

Overview

The STK551-3A0A-E is a three-phase inverter hybrid integrated circuit (HIC) manufactured by onsemi. It operates within an operating supply voltage range of 0 V to 450 V and supports an output current of 20 A. The device features a maximum collector-emitter voltage (VCEO) of 600 V and has a power dissipation rating of 39 W. It is designed for operation across a temperature range from -40°C to +100°C. The component utilizes Silicon technology and is housed in a SIP-29 package with through-hole mounting style, supporting an operating frequency of 20 kHz.

Feature Summary

• Integrates three half-bridge circuits into a single intelligent power module for compact motor drive solutions.
• Provides high-voltage isolation and protection capabilities inherent to the hybrid integrated circuit design.
• Supports robust thermal performance suitable for demanding industrial environments.

Applications

• Industrial motor control systems
• Three-phase inverter applications
• Motion control drives

Procurement Notes

Verify the specific suffix and revision level against the official datasheet to ensure compatibility with existing designs. Confirm that the SIP-29 through-hole package aligns with the target PCB footprint and assembly processes. Check for any recent product change notices or end-of-life notifications from onsemi, as availability may be limited for this discontinued series.

Selection Notes

Select this component when a pre-integrated three-phase inverter solution is required to reduce board space and simplify gate drive circuitry. Ensure the application voltage does not exceed 600 V and current requirements stay within the 20 A limit. Consider the thermal management needs given the 39 W power dissipation rating and the specific operating temperature range constraints.
