POWER SUPPLY 3/5
• If the positive drive pulse at Gate is less than 8 volts
(refer to Source), the MOSFET will get very hot to
damage. If the drive pulse is not sharp or is very noise, it
makes MOSFET very hot also.
• If the drive pulse is low & noisy, the drive IC or
peripheral parts may be defective or the power supply
may not be functioning properly.
• When handling the MOSFET, try not to touch the pins
with your fingers.
• It is preferable to use anti-static iron when soldering the
MOSFET.
• When the pair of MOSFETs are damaged, sometimes the
drive IC becomes defective too. Check the drive circuit
before replacing the MOSFETs, to prevent the power
MOSFET from shorting again.
