LM195/LM395
Ultra Reliable Power Transistors
ance, it is necessary to insert a 5.0k resistor in series with
the base lead to prevent possible emitter follower oscilla-
tions. Although the device is usually stable as an emitter fol-
lower, the resistor eliminates the possibility of trouble without
degrading performance. Finally, since it has good high fre-
quency response, supply bypassing is recommended.
General Description
The LM195/LM395 are fast, monolithic power integrated cir-
cuits with complete overload protection. These devices,
which act as high gain power transistors, have included on
the chip, current limiting, power limiting, and thermal over-
load protection making them virtually impossible to destroy
from any type of overload. In the standard TO-3 transistor
power package, the LM195 will deliver load currents in ex-
cess of 1.0A and can switch 40V in 500 ns.
For low-power applications (under 100 mA), refer to the
LP395 Ultra Reliable Power Transistor.
The LM195/LM395 are available in the standard TO-3, Kovar
TO-5, and TO-220 packages. The LM195 is rated for opera-
tion from −55˚C to +150˚C and the LM395 from 0˚C to
+125˚C.
The inclusion of thermal limiting, a feature not easily avail-
able in discrete designs, provides virtually absolute protec-
tion against overload. Excessive power dissipation or inad-
equate heat sinking causes the thermal limiting circuitry to
turn off the device preventing excessive heating.
Features
n Internal thermal limiting
n Greater than 1.0A output current
n 3.0 µA typical base current
n 500 ns switching time
The LM195 offers a significant increase in reliability as well
as simplifying power circuitry. In some applications, where
protection is unusually difficult, such as switching regulators,
lamp or solenoid drivers where normal power dissipation is
low, the LM195 is especially advantageous.
n 2.0V saturation
The LM195 is easy to use and only a few precautions need
be observed. Excessive collector to emitter voltage can de-
stroy the LM195 as with any power transistor. When the de-
vice is used as an emitter follower with low source imped-
n Base can be driven up to 40V without damage
n Directly interfaces with CMOS or TTL
n 100% electrical burn-in
