TN1605H-8G-TR

Scrs Overview

The TN1605H-8G-TR 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 16 A and offers a repetitive peak off-state voltage of 800 V. The device operates at junction temperatures up to 150 °C and features a tight gate triggering current spread between 5 mA and 8 mA. It provides high static dV/dt immunity of 500 V/µs and a turn-on current rise rate of 100 A/µs.

Scrs Feature Summary

• High thermal performance enabling operation at junction temperatures up to 150 °C
• Robust noise immunity with high static dV/dt characteristics
• Tight gate triggering current distribution for consistent switching behavior
• ECOPACK2 compliant construction with halogen-free molding and lead-free plating

Scrs Applications

• Inrush current limiting circuits in AC/DC converters
• General purpose AC line load switching
• Heating resistor control and solid state relays
• Crowbar and power bus discharge protection circuits

Scrs Procurement Notes

Verify the specific ordering code TN1605H-8G-TR to confirm tape and reel delivery mode, distinct from the tube-packaged TN1605H-8G. Ensure component authenticity through authorized STMicroelectronics channels. Confirm that the D²PAK footprint matches PCB design requirements before procurement.

Scrs Selection Notes

Select this component when designing systems requiring high thermal stability and robust surge handling capabilities. The 800 V rating suits general AC mains applications, while the 16 A capacity supports moderate power loads. Verify that the control circuit can accommodate the specified gate triggering current range for reliable turn-on.

Scrs Part Context

This part belongs to the TN1605H series of high-temperature SCRs designed for demanding industrial environments. The 'TR' suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly processes, differing from the standard tube packaging of the base model.

Scrs Replacement Considerations

Direct replacements must match the 800 V blocking voltage, 16 A RMS current rating, and D²PAK package outline. Verify equivalent thermal resistance and gate triggering specifications to ensure circuit compatibility without redesigning the control logic.
