This listing is for 1/2/5Pcs BU406 power transistor. I purchased a surplus lot of this item to make 1.7MHz ultrasonic self oscillating peizo nebulizer boards and am selling off the excess. The brand name is TSL, the specifications or properties for this transistor are no different to any other so any datasheet for the model is applicable.

Note: these are brand new transistors, it is common for heavy duty transistors to have the heatsink part coarsely ground down and flat as is shown in the image.

Default postage is by large letter, packaged in an anti-static bag.
A registered letter option is available using the new tracked auspost letters for around $6
