QJ6016RH4TP

Triacs Overview

The QJ6016RH4TP is a high-temperature Alternistor triac manufactured by Littelfuse, designed for robust power control applications. It features a rated repetitive off-state voltage (VDRM) of 600 V and an on-state RMS current (It RMS) of 16 A. The device operates within a temperature range of -40 °C to +150 °C. Key electrical parameters include a gate trigger current (Igt) of 35 mA, a holding current (Ih) maximum of 50 mA, and an on-state voltage of 1.6 V. It utilizes a TO-220AB package with non-isolated mounting.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• High thermal stability supporting operation up to 150 °C
• Non-isolated construction in a standard through-hole package

Triacs Applications

• Industrial motor speed control systems
• High-temperature heating element regulation
• General purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix RH4TP against official Littelfuse documentation to confirm the exact gate trigger characteristics and thermal specifications. Ensure the procurement channel provides valid RoHS compliance data. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards before finalizing orders.

Triacs Selection Notes

Select this component when high junction temperatures are expected, as it supports up to 150 °C. The 16 A RMS rating suits moderate power loads requiring reliable AC switching. Consider the non-isolated nature for heatsinking requirements. Validate that the 35 mA gate drive current matches the available control circuitry capabilities for proper triggering.

Triacs Part Context

This part belongs to the QJ series of high-temperature triacs from Littelfuse. It shares the Alternistor architecture with other models like QJ6016LH4TP but differs in isolation and specific gate parameters. The TO-220AB form factor allows for direct board mounting or chassis attachment using standard hardware.

Triacs Replacement Considerations

QJ6016LH4TP offers similar electrical ratings but features an isolated case configuration. Verify if electrical isolation between the case and terminals is required for the application safety design before substituting.
