PTC Thermistors, Mini Chips
for Over-Temperature Protection
Vishay BCcomponents
APPLICATION SPECIFIC DATA
Negative Temperature Coefficient (NTC) thermistors are well known for temperature sensing. What is not well known, however,
is that Positive Temperature Coefficient (PTC) thermistors can be used for thermal protection. Although their operating principles
are similar, the applications are very different; whereas NTC thermistors sense and measure temperature over a defined range,
PTC thermistors switch at one particular temperature.
Just like thermostats they protect such equipment and components as motors, transformers, power transistors and thyristors
against overtemperature. A PTC thermistor is less expensive than a thermostat, and its switch temperature can be more
accurately specified. It is also smaller and easier to design-in to electronic circuitry.
The PTC thermistor is mounted in thermal contact with the equipment to be protected, and connected into the bridge arm of a
comparator circuit, such as shown in Fig. 1. At normal temperature, the PTC thermistor resistance (Rp) is lower than Rs (see
Fig. 2), so the comparator's output voltage VO will be low. If an equipment overtemperature occurs, the PTC thermistor will quickly
heat up to its trigger or nominal reference temperature Tn, whereupon its resistance will increase to a value much higher than Rs,
causing VO to switch to a high level sufficient to activate an alarm, relay or power shutdown circuit.
