The T435-800H is a high-performance triac manufactured by STMicroelectronics, designed to manage AC loads with a current up to 4 A. It is a member of ST's Snubberless™ high-temperature series, which is particularly suited for applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance.

Key Features

• Current Rating: The T435-800H can handle continuous on-state currents up to 4 A, making it suitable for a variety of moderate power applications.
• Voltage Capability: With a blocking voltage of up to 800 V, it can be used in circuits with high off-state voltage requirements.
• High-Temperature Performance: This triac is designed to operate reliably at junction temperatures up to 150°C, accommodating environments with elevated temperatures.
• Snubberless Technology: The Snubberless™ design allows the T435-800H to switch more efficiently and with less electromagnetic interference (EMI), reducing the need for additional snubber circuit components.
• Gate Trigger Current: It features a specified gate trigger current of 35 mA, which is the maximum required to switch the device from off to on state.
• Package: The device comes in a through-hole TO-220AB package, which is widely used and easy to mount on printed circuit boards.
