NTE109
Germanium Diode
Fast Switching General Purpose
Description:
The NTE109 is a high conductance device with good switching characteristics for low impedance cir-
cuits, high resistancehigh conductance for efficient coupling, clamping and matrix service, and for-
ward and inverse pulse recovery for critical pulse applications.

Note 1 The continuous inverse operating voltage rating, V
cont
must be reduced when the diode is
operated at elevated junction temperature. The percent derating of V
cont
for each 10
C tem-
perature increment above 25
C is equal to V
cont
/10. For critical high temperaturehigh volt-
age applications, is recommended that diodes be 100% tested and specified at the elevated
temperature.
Note 2 The peak operating current is generally the controlling factor in AC rectifier service and may
be exceeded for pulses of less than 200
s duration.
