This device is designed primarily for low level audio and general
purpose applications with high impedance signal sources. Sourced
from Process 52.
Absolute Maximum Ratings*
TA = 25C unless otherwise noted
MMBFJ201
MMBFJ202
*
These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations
