I checked Toshiba's data sheet and oddly, their gains are different
than Philips'; they have 4 ranges instead of 3:

This part was originated by Toshiba, if I'm reading the Kanji in my
Japanese transistor book correctly.

Note: hFE classification:
O: 70~140, Y: 120~240, GR: 200~400, BL: 350~700

They don't have the low beta part "O" at all and add a "no suffix" bin
that can be any of Y, GR, BL. ;-)


Suffix Beta (Toshiba) Beta (Philips)
none N/A 120~700
O 70~140 N/A
Y 120~240 120~240
GR 200~400 200~400
BL 350~700 350~700
