Overview
The Powerex T600041804BT is a single Silicon Controlled Rectifier (SCR) phase control module designed for high-power industrial applications. It features a peak repetitive off-state voltage of 400V and an average on-state current rating of 175A. The device utilizes a TO-209AB package style, equivalent to the TO-93 form factor, suitable for chassis or stud mounting. Key electrical characteristics include a gate trigger voltage of 3V and a maximum gate trigger current of 150mA. The breakover current ranges from 4000A to 5500A, ensuring robust performance in phase control circuits requiring reliable switching capabilities.
Feature Summary
- Single SCR configuration optimized for phase control applications
- High surge current capability with breakover current up to 5500A
- Low gate trigger voltage requirement for efficient drive compatibility
- Durable construction supporting chassis or stud mounting methods
Applications
- Industrial motor speed control systems
- AC power regulation and phase firing circuits
- Welding equipment power supplies
- Heating element control units
Procurement Notes
Verify component authenticity through authorized Powerex distributors or direct manufacturer channels. Confirm that the received unit matches the T600041804BT designation and TO-209AB/TO-93 physical dimensions. Inspect terminals for corrosion or damage prior to installation. Ensure storage conditions maintain moisture sensitivity level 1 integrity. Cross-reference datasheet specifications against application requirements to validate voltage and current margins.
Selection Notes
Select this component when designing circuits requiring a single-phase SCR with 400V blocking capability and 175A continuous current handling. Consider the TO-209AB package constraints for thermal management and mechanical mounting space. Evaluate gate drive requirements against the 3V trigger voltage and 150mA current limit. Ensure the application environment supports the specified operating temperatures and thermal dissipation needs associated with this power module format.
Part Context
This part belongs to Powerex's discrete thyristor lineup, specifically engineered for phase control duties. It complements other series components like the T6071115B4BT, which offers higher voltage ratings but different current profiles. The T600041804BT represents a standard solution for medium-voltage AC control applications where robustness and predictable triggering are critical design parameters.
Replacement Considerations
Direct substitutes must match the 400V/175A specification and TO-209AB/TO-93 package outline. Verify pinout compatibility and thermal resistance values before substitution. Alternative parts should exhibit similar gate trigger characteristics to ensure circuit stability without redesigning the drive logic.
