Well, WES Components is at it again. I was at a mate's workshop the other day and his TV tech had been tearing his hair out, after replacing BUZ19A MOSFETs in a TV. He then tried some IRF substitutes (also sourced from WES) and they blew up as well. Careful examination revealed the leads seemed thinner than expected. A MOSFET sourced from Farnell solved the problem. Of course, WES will refund the cost of the blown MOSFETs, but who pays for the

What was the part number?

**BUZ19A was one. The other was an IRF number. That is the real worry. Completely different part numbers, different (alleged) manufacturers, but the same crappy part. I'll check with my mate tomorrow and report the details of the other part involved, along with the resolution reached with WES.
**Maybe. They were TO220 packs though. A little hard to pull apart. [ASIDE] A while ago, my mate posted a pic of a remote control that had gotten wet. His customer put it in a microwave oven to dry it out......

** Doubt it.It don't exist.
But BUZ91A fits the bill.

Overall the service from WES components is non existent. They stuffed up my order the other day ( yet again) and the guy on the other end of the phone just didn't care. Whey you stuff up you pay, when they stuff up you pay as well, I find WES a complete pack of bastards and wouldn't recommend anyone to use them anymore.
**As Phil correctly commented, the part number was a BUZ91A. The other part was a SSP6N60. Critically, they were allegedly from different manufacturers, the packaging was identical, right down to the thin leads. My mate has not been back to WES to complain yet.

rs,
tStrange that, I built the Deluxe Battery Zapper kit from Jaycar and the MOSFETs supplied (same SSP6N60 types) died a quick death. The physical construction of the TO220s looked like garbage, the metal in the legs were so soft that just bending them produced deep stress cracks.
Out of desperation, DSE equivalents were successfully used to replace them.
Should have persued it, but didn't due to time and motion or a lack there of.
