for phase cutting control we would like use either BTA16 (T0-220AB) or T1635 (D2PAK) on ouer PCB.the controlsignal is a 3,3 VDC pwm. ( see attachment ) A T1635H-6T is placed instead the T1635 in the boom list by a mistake .

now we have following situation.the circuit works fine at using the BTA16at using the T1635H-6T the hase cutting doesn't works ( full wave is engaged over the PWM range )Questions:a. what is the difference between T1635 and T1635H-6T ?b.how can we so...

we use the triac BTA/BTB16 for 1 Phase Control of a Feeder ( 230 VAC, 50 Hz). attached the LTspice- Simulation. Question: why is the current not symetric ? Bernd
