T501N70TOHXPSA1

Overview

The T501N70TOHXPSA1 is a high-power Silicon SCR module manufactured by Infineon Technologies, designed for demanding industrial applications. It features a rated repetitive off-state voltage (VDRM) of 7 kV and supports a non-repetitive peak surge current of 13.5 kA. The device has an on-state current rating of 860 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 350 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 350 mA. The leakage current at VDRM is specified at 200 mA. It utilizes a PCT circuit topology and is housed in the T-7626K package with press-fit mounting capabilities.

Feature Summary

• Engineered for high-voltage power control with a 7 kV blocking capability.
• Capable of handling extreme surge currents up to 13.5 kA for robust fault protection.
• Utilizes press-fit installation for secure mechanical connection and thermal management.

Applications

• High-voltage direct current (HVDC) transmission systems
• Industrial motor drives requiring high surge tolerance
• Power supply units for heavy machinery

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct configuration. Confirm that the T-7626K package dimensions align with the target assembly requirements. Check for RoHS compliance status via the manufacturer's official channels before integration into regulated products.

Selection Notes

Select this component when system design requires a 7 kV voltage rating combined with high surge current resilience. Ensure the cooling solution accommodates the thermal characteristics of the T-7626K package. Verify that the gate drive circuit can provide the required 350 mA trigger current reliably under all operating conditions.

Part Context

This part belongs to Infineon's high-power thyristor module portfolio, specifically designed for phase control and rectification applications. It represents a specialized solution for ultra-high voltage environments where standard discrete devices are insufficient. The TOH suffix indicates a specific packaging and terminal configuration variant within the broader T-series family.

Replacement Considerations
