TN3015H-6G

Scrs Overview

The TN3015H-6G is a high-temperature silicon controlled rectifier (SCR) manufactured by STMicroelectronics, housed in a D²PAK surface-mount package. It supports an RMS on-state current of 30 A and a peak off-state voltage of 600 V. The device operates at junction temperatures up to 150 °C with a maximum gate triggering current of 15 mA. Key electrical parameters include a non-repetitive surge peak on-state current of 295 A, a critical rate of rise of on-state current of 100 A/µs, and a minimum static dV/dt immunity of 1000 V/µs at 150 °C.

Scrs Feature Summary

• High thermal performance enabling operation at junction temperatures up to 150 °C
• Robust noise immunity with a static dV/dt rating of 1000 V/µs at elevated temperatures
• Optimized gate sensitivity balancing trigger current requirements against turn-on speed

Scrs Applications

• General purpose AC line load switching
• Motorbike voltage regulator circuits
• Inrush current limiting circuits
• Motor control circuits and starters
• Heating resistor control and solid state relays

Scrs Procurement Notes

Verify the specific ordering suffix when sourcing components. The base part number TN3015H-6G denotes tube packaging, while the suffix -TR indicates tape and reel delivery. Confirm that the received component marking matches the datasheet specifications to ensure authenticity and correct package type before integration into designs.

Scrs Selection Notes

Select this component for applications requiring compact SMD layouts combined with high thermal stability. The D²PAK package facilitates automated manufacturing while supporting robust heat dissipation. Ensure the design accommodates the specified 15 mA gate trigger current and utilizes adequate copper pad area to maintain thermal resistance within acceptable limits during continuous operation.

Scrs Part Context

This SCR belongs to the TN series of high-temperature thyristors designed for demanding power control environments. The D²PAK form factor provides a balance between current handling capacity and board space efficiency. The device is compliant with ECOPACK2 environmental standards, ensuring lead-free construction and halogen-free molding compounds suitable for modern electronic assemblies.

Scrs Replacement Considerations

Direct pin-compatible replacements within the same manufacturer family include the TN4015H-6G for higher current ratings or the TN1605H-6G for lower current requirements. Verify that any substitute maintains the required 600 V blocking voltage and 150 °C operating temperature range to ensure circuit reliability.
