10pcs E13009 NPN High Voltage Power Transistor TO-220.

Arrived next day, Brand name parts, Work as they should.

I am in the process of repairing a UV Fly Trap that malfunctioned. Two MJE-13003 NPN transistors were damaged, and the resistors between the VDC and Base for each transistor were burnt to a crisp. Additionally, a DIAC was toasted. While I could have replaced the components with identical ones, I opted for parts with better specifications. I suspect the designers of my initial fly trap electronic ballast recognized these issues and subsequently redesigned the ballast. I used a similar tester, and it identified the components correctly. I recommend using a standard multimeter with diode testing capability for such repairs.

Didn't dislike anything about this

Use it for fix my ozone generator. Works great.

This Item is not recognized as NPN transistor, Markings on the item: E13009-2 , however, component tester recognizes this as a Thyristor. So, markings on the unit for transistor, inside - Thyristor....

nice part fast service

Amazing for what it is I used this for my science fair project worked great and the shipping came only in one day I would buy again

This is a great set of high speed high voltage mosfets
