It is designed to replace mechani- cal (bimetal) temperature limit switches and offers increased ruggedness, higher reliability and greater setpoint accuracy. It requires no external components. The TC626 operates over a – 55 °C to +125°C tempera- ture range. It is available in a TO-92 package, which is ideal for ambient temperature sensing applications. It is also available in a TO-220-3 package for heatsink temperature measurement applications.
