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

Small Signal Diode

Absolute Maximum Ratings* Ta=25°C unless otherwise noted

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

NOTES:

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

2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.
