TDA2030
considered as being peak power limiting rather than simple current limiting. It reduces the possibility that the device
gets damaged during an accidental short circuit from AC output to Ground.
The presence of a thermal limiting circuit offers the following advantages:
The recommended values of the components are those shown on application circuit of Fig.14. Different values can
be used. The following table can help the designer.
COMPONENT
UTC assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or
other parameters) listed in products specifications of any and all UTC products described or contained
herein. UTC products are not designed for use in life support appliances, devices or systems where
malfunction of these products can be reasonably expected to result in personal injury. Reproduction in
whole or in part is prohibited without the prior written consent of the copyright owner. The information
presented in this document does not form part of any quotation or contract, is believed to be accurate
and reliable and may be changed without notice.
The UTC TDA2030 has an original circuit which limits the current of the output transistors. This function can be
1).An overload on the output (even if it is permanent),or an above limit ambient temperature can be easily
2).The heatsink can have a smaller factor of safety compared with that of a congenital circuit, There is no

supported since the Tj can not be higher than 150°C
possibility of device damage due to high junction temperature increase up to 150°C, the thermal shut-down
simply reduces the power dissipation and the current consumption.
