## **Features** - 8 A medium current Triac - 800 V symmetrical blocking voltage - 150 °C maximum junction temperature Tj - Three triggering quadrants - High noise immunity - static dV/dt - Robust dynamic turn-off commutation - (dl/dt)c - ECOPACK2 compliant component - Molding resin UL94-V0 flammability certified ## **Applications** - General purpose AC line load control - AC induction and universal motor control - Lighting and automation I/O control - Water heater, room heater and coffee machine - Home automation smart AC plug - Inrush current limiter in AC DC rectifiers ## **Description** ## **Product status link** T835H-8G |**Product summary**|**Product summary**| |---|---| |**IT(RMS)**|8 A| |**VDRM/VRRM**|800 V| |**VDSM/VRSM**|900 V| |**IGT**|35 mA| |**Tj max.**|150 °C| Specifically designed to operate at 800 V and 150 °C, the T835H-8G Triac housed in D[2] PAK provides an enhanced thermal management: this 8 A Triac is the right choice for a compact drive of AC loads and enables the heatsink size reduction. D[2] PAK package is ideal for compact SMD designs on surface mount boards or insulated metal substrate boards. Based on the ST high temperature Snubberless technology, it offers higher specified turn off commutation and noise immunity levels up to the Tj max. The T835H-8G safely optimizes the control of the hardest universal motors, heaters and inductive loads for industrial control and home appliances. Snubberless is a trademark of STMicroelectronics. **DS13570** - **Rev 1** - **November 2020** For further information contact your local STMicroelectronics sales office. www.st.com **T835H-8G Characteristics** **1 Characteristics** **Table 1.
