OB2262AP OB2262 DIP-8

Anyway this test is not applicable triacs that require high gate voltage and current for triggering. Thanks for pointing out. Leave a Reply Cancel reply Your email address will not be published.

Previous post Next post. Yes now it is ok and working Mt2 and Mt1 must be reversed otherwise it is not working I was tried many times I would like to thanks all of you for the tips. MT1 and MT2 are labelled back to front. How to test an LDR. The multimeter will show a high m110lz47 reading open circuit.

Thanks for datxsheet help! This circuit is nothing but a simple arrangement to demonstrate the elementary action of a triac. Connect triac to the circuit as shown in circuit diagram and switch S2 ON. Almost all type of triacs can be tested using this circuit.


m10lz47 datasheet & applicatoin notes – Datasheet Archive

The multimeter will now show a low resistance reading indicating the switch ON. Please correct the diagram. The lamp must glow indicating the switching ON of triac. If the above tests are positive you can assume that the triac is healthy. Great step by step instruction.

But you cannot trigger the gate by connecting it to the same potential as MT1. Wireless mains voltage tester. This is another approach for testing a triac.

Circuit for testing a triac. You may also like: Eric, MT1 and MT2 have to be reversed, as you datasheett. When you release the push button, you can see the lamp extinguishing. IIRC the description of the test circuit has an error: Please research this point and correct the fucking diagram, you retards, instead of wasting peoples time.

Testing triac using a multimeter. Now press the push button switch S1. The triac test circuit shown is incorrect and will not work as shown. If wired that way it datashewt work correctly.

Are these some other types of triacs, in behaviour or so, than the TIC ones? If the input is AC or pulsed DC, the lamp stays on while S1 is held closed, and then turns off at the next zero-crossing — i. They are definately different. First put the multimeter selector switch in a high resistance mode say Kthen connect the positive lead of multimeter to the MT1 terminal of triac and negative lead to the MT2 terminal of triac there is no problem if you reverse the connection.


The drive must go from MT2 to G. A multimeter can be used to test the health of a triac. Your email address will not be published. I agree with the previous comments. MT2 should be at the top and MT1 at the bottom, next to the gate G.

Trigger voltage in phase with MT2 at top to allow triac to operate in the first and daatsheet quadrants when AC is normally applied. I just tested it on an actual part. How to test a triac. Now put the selector switch to a low resistance mode, connect the MT1 and gate to positive lead and MT2 to negative lead.
