Hey there

I would really appreciate some suggestions as to a suitable alternative to the PS2521 opto isolator? I have attached a datasheet.

I have pulled a couple of these off a control board. It says "5E 2521 G" I am assuming that this is the same as the PS2521 part. It is situated on the board next to several TLP557 opto-isolators.

Any ideas please??

Many thanks in advance.

Is the opto in a 4-pin surface mount or through-hole package?

What makes this opto-coupler unique is its high input current rating (150mA) and CTR based upon a high current (100mA)

Hi there

The existing device is a 4 pin DIP (Thru hole).

Any ideas for a suitable replacement? Being in the UK, devices from rswww.com or farnell.co.uk or maplin are best .

Many thanks again!

Hi!

In the end I was able to find some PS2521 on Mouser - they're on their way!

Many thanks for your help.
