AS395 Matched PNP transistor
pair |
The AS395 dual monolithic PNP transistor offers excellent parametric
matching and high frequency performance. Low noise characteristics (1
nV/√Hz typ @ 1 kHz), high bandwidth (190 MHz typical), and low offset
voltage (100 μV max), makes the AS395 an excellent choice for demanding
preamplifier applications. Tight current gain matching (3% max mismatch)
and high current gain (100 min), over a wide range of collector current,
makes the AS395 an excellent choice for current mirrors. A low value of
bulk resistance makes the AS395 an ideal component for applications
requiring accurate logarithmic conformance.
To insure the long-term
stability of the matching parameters, internal protection diodes across
the base-emitter junction clamp any reverse base-emitter junction
potential. This prevents a base-emitter breakdown condition which can
result in degradation of gain and matching performance due to excessive
breakdown current.
The AS395H, AS395CH are available in the 8-pin
metal can TO5-8.
