Energy transistors produce a variety of warmthhttps://onlinehelp-uk.com and are subsequently often mounted on a bit of aluminium with finshttps://onlinehelp-uk.com called a HEATSINK. Most multimeters cannot test the LED on the input of an opto-coupler as a result of the ohms vary does not have a voltage excessive enough to activate the LED with at the least 2mA.cool electronics

Most logic circuits function on 5v and a Logic Probe is related to the 5v provide so the readings are accurate for the voltages being examined. The impedance of a diode or LED is EXCESSIVE before the device sees a voltage higher than the junction voltage after which it turns into LOW Impedance.cool electronics

Generally a transistor will only break-down when a voltage is presenthttps://onlinehelp-uk.com or it may be influenced by different components.
