Finding proper replacement rectifier

[unimatrix93]

Hello everyone,

I'm trying to fix up my battery charger. Where I found a dead schottky rectifier.

This is the dead component PTR30L120CTF:
PTR30L120CTF datasheet(1/7 Pages) PFC | 30A 120V HPTR Schottky Rectifier (alldatasheet.com)

And I have a spare 30CPQ150:
30CPQ150 datasheet(1/5 Pages) IRF | SCHOTTKY RECTIFIER (alldatasheet.com)

Can I use this diode as a replacement or if not, can you recommend me a proper replacement?
I cannot find the exact unit anywhere besides aliexpress and such.

Thank you guys!

Looks good to me.

What make/model is the battery charger?
The IR part will run 20% hotter at 15A, it is lower efficiency, higher voltage (drop).

It's a Husqvarna QC330 battery charger.

It's cooled by a heatsink + fan, so I hope it's will endure.

OK I'd asked to know the battery voltage because 120V 30A Schottky is a bit high voltage so I was wondering.
Higher PIV voltage diodes have a higher voltage drop and thus a bit more heat. But it's got a fan and the new diodes are bigger TO-247 (vs TO-220) with heatsink compound should run fine.

Husqvarna QC330 is not a reliable charger, many complaints about it. Seems to be 36V 330W for 2.5Ah cells in BLi100.

schottky's need to be rated very high - ideally 10x the actual voltage because even a short spike above the rating can damage them.
