Overview
The T507027084AQ is a Silicon Controlled Rectifier (SCR) manufactured by Powerex Inc., designed for high-power industrial applications. It features a standard recovery characteristic and utilizes a TO-94 stud mount package for efficient thermal management. The device supports an average on-state current of 70 A and an RMS on-state current of 110 A, with a maximum non-repetitive surge current of 1200 A at 60 Hz. It offers a blocking voltage of 200 V and operates within a junction temperature range of -40°C to 125°C. Key electrical parameters include a maximum gate trigger voltage of 3 V and a maximum on-state voltage of 3.5 V.
Feature Summary
- Standard recovery type construction optimized for general-purpose rectification tasks
- Stud mount configuration in TO-94 package ensuring robust mechanical stability and heat dissipation
- High surge current capability supporting transient load conditions
Applications
- Industrial motor drives and control systems
- Power supply circuits requiring high current handling
- Inverter and converter topologies in energy systems
Procurement Notes
Verify the specific suffix 'AQ' against the manufacturer's official datasheet to confirm exact material composition and compliance status. Ensure that the TO-94 stud mounting interface matches the thermal design requirements of the target application. Cross-reference the part number with authorized distributors to confirm current availability and lead times, as inventory levels fluctuate based on production schedules.
Selection Notes
Select this component when a 200 V blocking voltage and 70 A continuous current rating are required in a stud-mount form factor. Consider the standard recovery time if reverse recovery characteristics do not demand ultra-fast switching. Evaluate the thermal resistance of the TO-94 package relative to the expected ambient temperature and cooling method to ensure operation remains within the specified -40°C to 125°C junction temperature range.
Part Context
This SCR belongs to the T507 series from Powerex Inc., which focuses on high-current power electronics solutions. The series typically includes variants with different voltage ratings and current capacities, all sharing the robust TO-94 stud mount architecture. This specific model represents a lower voltage option within the family, suitable for applications where moderate blocking voltage is sufficient but high current capacity is critical.
Replacement Considerations
Direct substitutes may include other 200V, 70A SCRs in TO-94 packages from manufacturers like Littelfuse or Vishay, provided pinout and thermal characteristics align. Verify that any replacement maintains the same standard recovery profile and gate trigger specifications to ensure circuit compatibility without redesign.
