Delivery 12 days from payment, paid for AliExpress standard shipping, The seller sent this way, the track in Russia was tracked. On the seller's site in the title error, bd140 is not NPN, But PNP, on the page there is datachite, it says PNP. I knew that pnp conductivity, but other buyers may not know it. I recommend the seller to correct this error. If you need NPN with the same characteristics, order bd139. I recommend the goods and the seller.
