QJ8035LH4TP

Overview

The QJ8035LH4TP is a bidirectional triac manufactured by Littelfuse, distinct from the IXYS brand specified in the query. It features an RMS on-state current of 35 A and a rated repetitive off-state voltage (VDRM) of 800 V. The device operates within a junction temperature range of -40°C to +150°C and utilizes a TO-220L-3 through-hole package. Key electrical parameters include a maximum holding current of 60 mA, a gate trigger voltage of 1 V, and a gate trigger current of 35 mA. The on-state voltage is specified at 1.55 V, with non-repetitive peak currents of 290 A and 350 A.

Feature Summary

• High-temperature operation capability up to 150°C for robust performance in demanding environments.
• Standard high-temperature Alternistor design providing reliable switching characteristics.
• Through-hole mounting configuration suitable for industrial power control applications.

Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• High-power lighting dimming circuits

Procurement Notes

Verify manufacturer identity carefully as the model number corresponds to Littelfuse, not IXYS. Confirm datasheet alignment with specific application requirements regarding thermal management and gate drive characteristics. Ensure component authenticity through authorized distribution channels to avoid counterfeit risks associated with high-current thyristors.

Selection Notes

Select this component when 35 A RMS current handling and 800 V blocking voltage are required in a TO-220L-3 package. Consider the 35 mA gate trigger current requirement for driver circuit design. Evaluate thermal dissipation needs given the 1.55 V on-state voltage drop at full load conditions.

Part Context

This part belongs to the QJxx30xH7 series of standard high-temperature triacs. It serves as a power switching element in AC control circuits. The TO-220L-3 package provides electrical isolation capabilities necessary for direct mounting to heat sinks in industrial power electronics assemblies.

Replacement Considerations

Cross-reference with other 35 A, 800 V triacs in TO-220 packages. Verify gate trigger current compatibility with existing drive circuits before substitution. Check pinout alignment and thermal resistance specifications to ensure equivalent performance in the target application.
