They can be used as ON/OFF function in applications such as static relays, heating regulation or induction motor starting circuit. They are also recommended for phase control operations in light dimmers and appliance motors speed controllers. The Snubberless™ versions (W suffix and T10xx) are especially recommended for use on inductive loads, because of their high commutation performance. By using an internal ceramic pad, the Snubberless™ series provide an insulated tab (rated at 2500 VRMS) complying with UL standards (file reference: E81734). ## **Product status link** ~~hs~~ |**Product status link**<br>~~hs~~| |---| |BTA10,BTB10,T1035,T1050| || |**Product summary**<br>~~hs~~| |**IT(RMS)**<br>10 A| |**VDRM/VRRM**<br>600 and 800 V| |**IGT**<br>25 to 50 mA| **DS3165** - **Rev 9** - **March 2019** For further information contact your local STMicroelectronics sales office. www.st.com **BTA10, BTB10, T1035, T1050 Characteristics** **1** ## **Characteristics** **Table 1.

STMicroelectronics is a global leader in the semiconductor industry, recognized for developing highly integrated, energy-efficient solutions that power modern electronics. With a strong focus on innovation, ST provides a comprehensive portfolio of microelectronics that address the demanding requirements of industrial, automotive, communications, and consumer applications. Our extensive selection of STMicroelectronics components is built around a robust lineup of discrete semiconductors and circuit protection devices. We offer a wide variety of single MOSFETs, Schottky diodes, and fast and ultrafast recovery rectifier diodes, designed to deliver exceptional efficiency and thermal performance in power management and conversion systems. For robust circuit protection, our inventory features hundreds of transient voltage suppressors and TVS diodes that safeguard sensitive electronic components against destructive voltage spikes. In addition to core power discretes like TRIACs, SCRs, bipolar transistors, and single IGBTs, our STMicroelectronics range includes specialized integrated passive filters and MEMS sensors. Furthermore, ST offers advanced integrated passive devices, such as baluns and RF filters, which utilize high-quality monolithic RF IPD processes on glass or high-resistance silicon substrates. These components provide competitive cost structures, reduced power losses, and simplified RFIC-to-antenna matching, ensuring optimal system performance and delivering the reliability required for next-generation wireless and power designs.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
