TN4015H-6G

Scrs Overview

The STMicroelectronics TN4015H-6G is a high-temperature Silicon Controlled Rectifier (SCR) rated for 600 V repetitive peak off-state voltage and 40 A RMS on-state current. It operates within a junction temperature range of -40°C to +150°C, featuring a gate triggering current of 15 mA maximum and a holding current of 60 mA maximum. The device supports a non-repetitive surge current of up to 394 A and offers a high dI/dt capability of 100 A/μs. Packaged in a surface-mount D2PAK (TO-263-2) format, it provides robust thermal performance suitable for compact designs.

Scrs Feature Summary

• High junction temperature operation up to 150°C enables reliable performance in thermally intensive environments.
• Integrated noise immunity with a dV/dt rating of 500 V/μs ensures stable switching under transient conditions.
• D2PAK surface-mount package facilitates compact PCB layouts and efficient heat dissipation.

Scrs Applications

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

Scrs Procurement Notes

Verify the specific suffix against official STMicroelectronics documentation to confirm package type and electrical ratings. Ensure compatibility with required thermal management solutions given the 150°C junction limit. Confirm RoHS compliance status via the manufacturer's datasheet before integration into final assemblies.

Scrs Selection Notes

Select this component when high thermal stability and surface-mount convenience are required for SCR applications. The 600 V rating suits standard AC line voltages, while the 40 A RMS capacity handles significant load currents. Consider the D2PAK footprint for space-constrained designs requiring robust thermal handling without through-hole mounting.

Scrs Part Context

This device belongs to STMicroelectronics' TN series of high-temperature SCRs, designed for demanding switching control applications. The series emphasizes reliability at elevated temperatures, offering a balance between noise immunity and gate sensitivity. It serves as a solid-state alternative to mechanical relays in AC power control scenarios.

Scrs Replacement Considerations

The TN4015H-6T is a pin-compatible leaded alternative in a TO-220AB package. Verify thermal resistance differences and mounting requirements when substituting between surface-mount and through-hole variants to ensure adequate heat sinking.
