[sdiy] AD821

[Paul Perry]

If you google...

"Part Number = AD821
Description = PNP Monolithic Transistor Pair - VBE1-2 1mV max
Manufacturer = Various
Number of Devices = 2
V(BR)CEO (V) = 45
I(C) Abs.(A) Collector Current = 20m
P(D) Max.(W) Power Dissipation = 500m
h(FE) Min. Static Current Gain = 150
@I(C) (A) (Test Condition) = 1m
@V(CE) (V) (Test Condition) = 5
f(T) Min. (Hz) Transition Freq = 100M
Semiconductor Material = Silicon
Package = TO-71
Military = N"

And, someone in China wants to sell you 200 ;-D

It was in vol 2 of the Analog Devices 1988 linear databook,
which I don't have.. but I bet Harry does!
