1N/FDLL 914A/B / 916/A/B / 4148 / 4448

Small Signal Diode

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

Note:

1. These ratings are limiting values above which the serviceability of the diode may be impaired.
