This is one of the transistor types.
Part Number: B817, 2SB817
Function: – 140V, – 12A, AF 60W Output Applications
Package: TO-3PB Type
Manufacturer: Sanyo Semicon Device
The B817 is PNP Epitaxial Planar Silicon Transistor.
The descriptions in parentheses are for the 2SB817 only : other descriptions than those in parentheses are common to the 2SB817 and 2SD1047.
1. Capable of being mounted easily because of onepoint fixing type plastic molded package (Interchangeable with TO-3).
2. Wide ASO because of on-chip ballast resistance.
3. Good depenedence of fT on current and excellent high frequency responce.
Absolute Maximum Ratings at Ta = 25°C
