STMicroelectronics T1235H, T1250H High Temperature 12 A Snubberless Triacs Datasheet
The T1235H and T1250H are medium current, 12 A Snubberless Triacs specifically designed for high power density or universal motor applications, such as vacuum cleaners and washing machine drum motors. These devices provide a very high switching capability up to junction temperatures of 150 °C, allowing for reduced heatsink requirements compared to traditional Triacs.
Available in through-hole (TO-220AB, TO-220AB Insulated) and surface mount (D2PAK) packages, the series features low thermal resistance with clip bonding and very high 3-quadrant commutation capability. The T12xxH-6l variant includes an internal ceramic pad for voltage insulation rated at 2500 V rms. The devices are RoHS compliant and UL certified.
