ACTT10B-800CTNJ

Overview

The ACTT10B-800CTNJ is a snubberless triac manufactured by WeEn Semiconductors, designed for AC thyristor power switching applications. It features an RMS on-state current of 10 A and a rated repetitive peak off-state voltage of 800 V. The device supports a non-repetitive peak on-state current of 99 A with a maximum on-state voltage of 1.3 V. Gate triggering requirements include a maximum gate trigger voltage of 1 V and a maximum gate trigger current of 35 mA. It operates within a junction temperature range up to +150 °C and is housed in a TO-220AB-3 through-hole package.

Feature Summary

• Snubberless design enabling full RMS current commutation at maximum rated junction temperature without external snubber circuits
• Enhanced high-temperature capability supporting operation up to 150 °C junction temperature
• Self-protective clamping structure providing safe withstand against low and high energy transients

Applications

• High-temperature AC power switching circuits
• Industrial motor control systems requiring robust transient protection
• Solid-state relays operating under harsh thermal conditions

Procurement Notes

Verify the specific suffix CTNJ against official datasheets to confirm pinout and marking orientation. Ensure compatibility with TO-220AB-3 mounting standards. Cross-reference RoHS and REACH compliance status directly with manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designs require snubberless operation to reduce bill of materials and board space. The 10 A rating suits moderate power loads, while the 800 V blocking voltage provides adequate margin for standard industrial AC lines. Verify that the 150 °C thermal limit aligns with the system's heat dissipation strategy.

Part Context

This part belongs to the ACTT series of enhanced triacs from WeEn Semiconductors, formerly NXP Semiconductors. The series is characterized by integrated clamping structures and high thermal stability. The ACTT10B variant specifically targets applications needing reliable switching at elevated temperatures without additional protective components.

Replacement Considerations

Direct substitutes may include other snubberless triacs from the same family with identical current and voltage ratings. Verify package compatibility and thermal characteristics before substitution.
