MARKING CODE of "L78L05ABUTR"

Hi. There is a question about "L78L05ABUTR" regulators. It's marking code is shown as "8C" in catalogue. But, It's actual product marking code is "8C033" (We bought "L78L05ABUTR" from Digi-Key.) I am curious what is right.

Triac control by pulse transformer

See AN436. I am using T1635-6G in a Hybrid Relay configuration following AN4993. Load is about 2kW at 230 VAC. Circuit works fine at with gate traiin of pulses (2kHz, DC = 50%). I want to trim parameters to optimum, at the moment transformer is make ...

Resolved! Mouser SO# 490877 Hello, a customer is requesting clarification that the ICs we shipped them for P/N: VN7050ASTR are the correct ICs as the marking only shows "VS7050A".

The customer expected the full part-number as marking..We pointed him to the mfr label which shows the correct part-number and the marking.The hint in the datasheet showing that the marking is limited to 7characters with the last 2chars of the P/N be...

Resolved! HI, I'm using a shield ihm13a1 with nucleo G431RB and DC motor, but I can't regulate the Vref, If I set a Vref = 1,6 (50% d.c) the motor doesn't move, I have set 80% d.c. to make it move. Any idea?

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...
