QJ8035NH4RP

Triacs Overview

The QJ8035NH4RP is a bidirectional TRIAC from the QJxx30xH9 series, manufactured by Littelfuse/IXYS. It features a 35 A RMS on-state current and an 800 V rated repetitive off-state voltage. The device supports non-repetitive surge currents of 290 A or 350 A depending on conditions. Key electrical parameters include a maximum on-state voltage of 1.55 V, a gate trigger voltage of 1 V, and a holding current of 60 mA. It operates within a temperature range of -40°C to +150°C and utilizes a D2PAK-2 (TO-263-2) surface mount package.

Triacs Feature Summary

• High-temperature operation capability with a maximum junction temperature of 150°C
• Robust surge current handling for high-power switching applications
• Sensitive gate triggering characteristics for microprocessor compatibility

Triacs Applications

• High-temperature AC power control systems
• Industrial motor speed regulation
• Solid-state relay modules requiring high thermal stability

Triacs Procurement Notes

Verify the manufacturer designation as Littelfuse or IXYS, as both entities are associated with this component lineage. Confirm the specific suffix 'H4RP' corresponds to the standard high-temperature variant in the QJxx30xH9 series. Ensure the ordering documentation specifies the TO-263-2 package type and validates RoHS compliance status prior to final procurement authorization.

Triacs Selection Notes

Select this component when applications demand high thermal endurance up to 150°C and significant surge current capacity. The 800V rating suits medium-voltage AC loads. Consider the TO-263-2 package for surface-mount assembly constraints. Verify that the 1V gate trigger requirement aligns with the driving circuit's output capabilities for reliable turn-on.

Triacs Part Context

This part belongs to the Alternistor TRIAC family, designed for robust performance in demanding environments. The QJxx30xH9 series emphasizes high-temperature reliability and surge tolerance. It serves as a solid-state switch alternative to mechanical relays in industrial settings where durability and long service life are critical operational requirements.

Triacs Replacement Considerations

The QJ8035RH4TP is a documented substitute offering identical 35A current and 800V voltage ratings but utilizes a TO-220 through-hole package instead of the TO-263-2 surface mount format. Verify board layout compatibility before substitution.
