LM195QML Ultra Reliable Power Transistors
1FEATURES DESCRIPTION
The LM195 is a fast, monolithic power integrated
2• Internal Thermal Limiting circuit with complete overload protection. This device,
• Greater Than 1.0A Output Current which acts as a high gain power transistor, has
• 3.0 μA Typical Base Current included on the chip, current limiting, power limiting,
and thermal overload protection making it virtually
• 500 ns Switching Time impossible to destroy from any type of overload.
• 2.0V Saturation The inclusion of thermal limiting, a feature not easily
• Base Can be Driven up to 40V Without available in discrete designs, provides virtually
Damage absolute protection against overload. Excessive
• Directly Interfaces with CMOS or TTL power dissipation or inadequate heat sinking causes
• 100% Electrical Burn-in the thermal limiting circuitry to turn off the device
preventing excessive heating.
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.
The LM195 is easy to use and only a few precautions
need be observed. Excessive collector to emitter
voltage can destroy the LM195 as with any power
transistor. When the device is used as an emitter
follower with low source impedance, it is necessary to
insert a 5.0k resistor in series with the base lead to
prevent possible emitter follower oscillations.
Although the device is usually stable as an emitter
follower, the resistor eliminates the possibility of
trouble without degrading performance. Finally, since
it has good high frequency response, supply
bypassing is recommended.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
θJA (package junction to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax - TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
