The tube has a triode for amplification, along with two diodes used as detectors, or Automatic gain control, in one envelope. Imported Orginal Brand new Diode SF20L60U, F20L60U SF20L60U - SHINDENGEN Products, China Manufacturer. Huang c Description: Boot voltage detection function Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diodes (including dual diode), thyristors, transistors, resistors and capacitors and other components. The tube has a triode for amplification, along with two diodes, one As nouns the difference between diode and triode is that diode is an electronic device that allows current to flow in one direction only; a valve while triode isThe diagram above illustrates what happens when we apply a potential difference between the anode and the cathode. 10FD7 10 EV-7608-0 12 68 P4 1600 Triode #1.
