Picoampere diode
BAV45
FEATURES
DESCRIPTION
• Extremely low leakage current:
max. 5 pA
Silicon diode in a metal TO-18 can. It has an extremely low leakage current over
a wide temperature range combined with a low capacitance and is not sensitive
to light.
• Low diode capacitance
• Light insensitive.
APPLICATION
a
• Clamping
I
• Holding
H—
k
• Peak follower
MAM207
• Time delay circuits
• Logarithmic amplifiers

and symbol.
• Protection of insulated gate
field-effect transistors.
CAUTION
Handle the device with care whilst soldering into the circuit. The extremely
low leakage current can only be guaranteed when the bottom is free from
solder flux or other contaminations.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
