B817 transistor Image and pinouts :
The descriptions in parentheses are for the B817 only : other descriptions than those in parentheses are common to the 2SB817 and 2SD1047.
For 60W audio frequency amplifier output stage, Complementary to 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.
4. 140V / 12A / AF 60W Output Applications
