FDLL4151 Small Signal Diode

FDLL4151
Small Signal Diode General Description
A general purpose diode that couples high forward conductance fast swiching speed and high blocking voltages in a glass leadless LL-34 surface mount package. Placement of the expansion gap has no relationship to the location of the cathode terminal which is indicated by the first color band.

NOTES:

These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.

1. These ratings are based on a maximum juction 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.
