Small Signal Diode

Ordering Information

Absolute Maximum Ratings(1), (2)

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-

ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The

absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes:

1. These ratings are based on a maximum junction temperature of 200

°C.

2. These are steady-state limits. Fairchild Semiconductor should be consulted on applications involving pulsed or

low-duty-cycle operations.
