PT8A3305LPE

Power Management - Specialized Overview

The PT8A3305LPE is a ceramic heating controller manufactured by Diodes Incorporated, designed for direct SCR drive in high watt density alumina heater systems. It operates on a supply voltage of 4V to 5.5V and supports dual AC voltages of 120VAC and 240VAC. The device features an internal 5V zener regulator and detects heater temperature without external sensors. It is housed in an 8-DIP package with a through-hole mounting type, operating within a temperature range of -20°C to 85°C.
