These are genuine NOS Toshiba´s. Seems the store only carries the Linear Syatem ones.
GR´s IDSS range is from 2-6mA, BL´s are 6-12mA..
Don´t know about your last Q, but ordering from the US will probably save you some customs hazzle.
Probably depends on the value written on the customs label.
Send me a PM if you want these. I certainly would hate to pour them out on my workbench and start the matching,
if I´m not sure you want them after I´ve gone through the trouble
PayPal is fine (family and friends or you pay the fee).
