T9G0021003DH

SCRs - Modules Overview

The T9G0021003DH is a single phase control SCR module manufactured by Powerex Inc. It features a disk button package with ceramic metal-sealed cofired construction. The device supports a maximum voltage of 200V and a continuous on-state current of 1,000,000 A (1 MA). Key electrical parameters include a gate trigger voltage max of 3 V, gate trigger current max of 200 mA, and a critical rate of rise of off-state voltage of 1000 V/us. Non-repetitive peak current reaches 17,000 A, with a circuit commutated turn-off time of 250 µs. Operating temperature ranges from -40 °C to 125 °C.

SCRs - Modules Procurement Notes

Verify component authenticity through authorized Powerex distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free certification prior to procurement. Ensure storage conditions maintain integrity of the ceramic metal-sealed package. Validate that the specific disk button form factor matches mechanical constraints of the target chassis mount assembly.

SCRs - Modules Selection Notes

Select this module when extremely high continuous current capacity is required alongside low voltage ratings. The 1 MA rating distinguishes it from standard SCR modules. Verify that the 200V blocking capability aligns with system voltage levels. Consider the 250 µs turn-off time for frequency limitations. Ensure gate drive circuits can supply the specified 3 V and 200 mA limits reliably.
