As power transistor handle large currents, they always heat up during operation. Since transistor is a temperature dependent device, the heat generated must be dissipated to the surrounding in order to keep the temperature within permissible limits. Generally, the transistor is fixed on a metal sheet (usually aluminum) so that additional heat is transferred to the Aluminum sheet. The metal Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4092621447904023766.post-80350231161833567532015-09-29T00:33:00.000+06:002016-05-23T14:25:26.803+06:00Automatic Power Off Circuit Diagram
It is an automatic power off circuit diagram. If you need to shut-off any electronic device after a set amount of time then this circuit can do that automatically; when you are even sleeping! For example this auto power off circuit can be used with garden/porch light, soldering iron/ glue gun or similar other devices to auto shut it off for saving electricity or save the device, or Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-4092621447904023766.post-62930845327907081542015-09-18T23:56:00.000+06:002015-09-19T01:33:44.124+06:0010W Audio Amplifier Circuit by TDA2030
The amplifier circuit by ic TDA2030 described here is an powerful audio amplifier with output power of 10W. TDA2030 is a monolithic IC, used as a low frequency class AB Amplifier. It has high output current and very low distortion. This 10W audio amplifier using TDA2030 is good for home/ small room.
