Overview
The STK621-033N1-E is a three-phase inverter power hybrid integrated circuit manufactured by onsemi. It integrates power elements, specifically IGBTs and Fast Recovery Diodes (FRDs), along with pre-driver circuits and protection mechanisms within a single package. Designed for AC motor applications, this component operates with a maximum junction temperature range of -20°C to 150°C and supports a continuous current capacity of 15A at 15V. The device utilizes a ZIG-ZAG package configuration.
Feature Summary
- Integrates IGBT and FRD power elements with pre-driver and protection circuits
- Designed for bridge driver applications in AC motors
- Supports high thermal operation up to 150°C junction temperature
Applications
- AC Motor drive systems
- Three-phase inverter bridges
- Industrial motor control units
Procurement Notes
Verify the specific suffix 'N1' against official datasheets, as availability data indicates potential confusion with the 'N' or 'D' variants. Confirm RoHS compliance status directly with the manufacturer documentation. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) prior to final design-in decisions. Ensure the ordering part number matches the exact pinout and thermal requirements of the target application.
Selection Notes
Select this component for designs requiring an integrated three-phase inverter solution with built-in protection. Consider the 15A current rating and 150°C thermal limit when sizing heatsinks. Verify that the ZIG-ZAG package fits the PCB footprint constraints. Compare against other STK621 series variants if different voltage ratings or packaging options are required.
Part Context
This part belongs to the STK621 series of three-phase inverter hybrid ICs from onsemi. These devices are categorized under Motor / Motion / Ignition Controllers & Drivers. The series typically combines power switching elements with control logic to simplify motor drive circuit design. Variants may differ in suffix codes indicating package type or specific electrical characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult onsemi technical support for direct replacements or evaluate similar STK621 series components such as STK621-033N-E or STK621-033D-E, verifying pin compatibility and electrical specifications independently.
