New Triacs in TO-3PF package improve creepage distance and noise immunity in high-condensation applications
The new family of SNUBBERLESS Triacs in TO-3PF package offer enhanced creepage distance and noise immunity. Optimized for on/off functions or phase-angle control, they enable applications dealing with high level of condensation, such as instant tap or shower water heaters, to comply with insulation coordination standards at Pollution degree 4. With an insulated tab rated at 2.5kV, they meet UL-1557 requirements. Offering high noise immunity, TO-3PF SNUBBERLESS Triacs simplify EMI standards qualification.
