Small Signal Diode
Absolute Maximum Ratings
(1)
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 T
A
= 25°C unless otherwise noted.
Note:
1. These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
These ratings are based on a maximum junction temperature of 200 °C.
These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle
operations.

Description
A general purpose diode that couples high forward con-
ductance fast switching speed and high blocking volt-
ages 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.
