TN4015H-6T

Scrs Overview

The TN4015H-6T is a high-temperature Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics. It features a non-isolated TO-220AB package and supports an average on-state current of 25 A with an RMS current rating of 40 A. The device withstands a peak off-state voltage of 600 V and handles a non-repetitive surge current of up to 394 A. It operates within a junction temperature range of -40°C to 150°C, ensuring robust thermal performance in demanding environments.

Scrs Feature Summary

• High junction temperature capability up to 150°C for enhanced thermal performance
• Balanced noise immunity and gate triggering characteristics for robust control circuit design
• ECOPACK2 compliant component construction

Scrs Applications

• Voltage regulators in motorbikes and industrial drives
• Overvoltage crowbar protection circuits
• Motor control circuits in power tools and kitchen aids
• Inrush current limiting circuits

Scrs Procurement Notes

Verify the specific suffix 'T' corresponds to the non-isolated TO-220AB package variant when sourcing. Confirm that the required application does not necessitate electrical isolation, as this model lacks internal insulation. Ensure compatibility with the specified thermal management requirements for operation at elevated junction temperatures.

Scrs Selection Notes

Select this component for applications requiring high thermal stability and compact control circuit designs. It is suitable where non-isolated mounting is acceptable. Consider the trade-off between its 500 V/µs dV/dt immunity and 15 mA gate trigger current for driver interface design. Verify that the 40 A RMS rating meets the continuous load requirements of the target system.

Scrs Part Context

This part belongs to the TN4015H series of high-temperature SCRs from STMicroelectronics. The series includes variants such as the TN4015H-6G (D²PAK surface mount) and TN4015H-6I (insulated TO-220AB). The TN4015H-6T specifically denotes the non-isolated version in the standard TO-220AB through-hole package, sharing similar electrical ratings with other series members but differing in physical isolation properties.

Scrs Replacement Considerations

For isolated requirements, consider the TN4015H-6I which offers 2500 VRMS insulation. For surface-mount needs, the TN4015H-6G provides equivalent electrical performance in a D²PAK package. Direct pin-to-pin replacement requires verifying package compatibility and isolation needs.
