TVS Diode. Component Guide 11


TVS DIODEP6KE12A is a very good TVS (Transient Voltage Suppressor ) Diode that can be fixed across the power supply lines to block the transients. It is rated 600 Watts and protects the sensitive electronic devices from the voltage spikes induced on circuit. It can handle up to 12 Amps current. Ideal device to attach across, Telephone lines, Cable TV lines, Transformer power supply etc. It works like a simple Lightning Arrester.

Electronic Guard


Inrush current at power on or power resumption after a power failure is the major cause of data loss and errors in Micro controller based electronic circuits.  This circuit gives a time delay of 2 minutes to stabilize the power before the device switches on.

Electronic Guard


This circuit can protect your Electronic devices like TV from inrush current. Very high spikes can develop at power on due to sparking in the switch and more serious effects occur when power resumes after a power failure due to high magnetic field in the distribution transformer. When we keep the TV in standby mode through remote, this high inrush current when power resumes can cause its permanent damage.

Trick to Protect TV


Here is a simple circuit to protect TV from high voltage spikes during lightning or a power surge in the cable. It can be incorporated in the Coaxial cable of TV Antenna or Set top box. It uses a GDT and Safety capacitor to provide protection from high voltage spikes. The same circuit can also protect Cable Modem and Telephone lines.

Trick to Protect Home Appliances


Here is a low cost Spike protector for Electric appliances, TV, Computer etc from high voltage spikes that appear in the power lines. Very high voltage spikes and transients develop momentarily in the supply lines when lighting occurs. Such short duration high voltage spikes also super impose on the mains when high current loads are switched on or when power resumes after a power failure due to high magnetic field in the distribution transformer. Even though the spikes are short living, they can cause permanent damage in appliances. This MOV based circuit can be added in the existing switch board to protect the appliances from high voltage spikes. If heavy transients develop in the mains, the MOV in the circuit short circuit the lines and the fuse will blow out.

Transil, Trisil and SIDAC


Transil is the trade name of Transient Voltage Suppression diode or TVS diode of ST Microelectronics, Transil diode is used to protect sensitive electronic devices from voltage spikes and transients induced by the mains. Transil protects the circuit by shunting excess current if the induced current exceeds the avalanche breakdown point. It works like a clamping diode to remove all the excess voltage induced. When the overvoltage condition goes off, the Transil automatically resets. Trisil is the trade name of the Thyristor Surge Protection device, another surge protector for electronic equipments. SIDAC is also a protection device less commonly used for surge protection for AC.
