M.S. Kennedy Corporation
The MSK 0002 is a general purpose current amplifier. It is the industry wide replacement for the LH0002. The
device is ideal for use with an operational amplifier in a closed loop configuration to increase current output. The MSK
0002 is designed with a symmetrical output stage that provides low output impedances to both the positive and
negative portions of output pulses. The MSK 0002 is packaged in a hermetic 8 lead low profile T0-5 header and is
specified over the full military temperature range.

APPLICATION NOTES
HEAT SINKING
To determine if a heat sink is necessary for your application
and if so, what type, refer to the thermal model and governing
equation below.
R
SA
= ((T
J
- T
A
)/P
D
) - (R
JC
) - (R
CS
)
= ((125C - 80C) / 0.36W) - 40C/W - 0.15C/W
= 125 - 40.15
= 84.9C/W
This heat sink in this example must have a thermal resistance
of no more than 84.9C/W to maintain a junction temperature
of no more than +125C.

Governing Equation:
Example:
This example demonstrates a worst case analysis for the buffer
output stage. This occurs when the output voltage is 1/2 the
power supply voltage. Under this condition, maximum power
transfer occurs and the output is under maximum stress.
Conditions:
VCC= 12VDC
Vo= 6Vp Sine Wave, Freq. = 1KHz
RL= 100
For a worst case analysis we will treat the 6Vp sine wave as
an 6 VDC output voltage.
1.) Find Driver Power Dissipation
PD= (Vcc-Vo) (Vo/R
L
)
= (12V-6V) (6V/100
)
= 360mW
2.) For conservative design, set T
J
=+125C Max.
3.) For this example, worst case T
A
=+80C
4.) R
JC
= 40 C/W from MSK 0002H Data Sheet
5.) R
CS
= 0.15 C/W for most thermal greases
6.) Rearrange governing equation to solve for R
