GENERAL DESCRIPTION
the system when measured temperature is above the fac-
tory-programmed setting. 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.
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.

... C lower than the trip point setting. The TC626VZB (TO-92 package) has a maximum out- put current of 10mA while the TC626VAB has a maximum output current of 50mA. Care must be taken to observe these output current limits as output currents in excess of those stated will cause device self-heating resulting in erroneous temperature measurements ...
