LM195, LM395 www.ti.com SNOSBO4C – JUNE 1999 – REVISED APRIL 2013 LM195/LM395 Ultra Reliable Power Transistors Check for Samples: LM195, LM395 FEATURES 1 • • • • • • • • 2 Internal Thermal Limiting Greater than 1.0A Output Current 3.0 μA Typical Base Current 500 ns Switching Time 2.0V Saturation Base Can be Driven up to 40V without Damage Directly Interfaces with CMOS or TTL 100% Electrical Burn-in For low-power applications (under 100 mA), refer to the LP395 Ultra Reliable Power Transistor. The LM195/LM395 are available in the standard TO3, Kovar TO-5, and TO-220 packages. The LM195 is rated for operation from −55°C to +150°C and the LM395 from 0°C to +125°C. Simplified Circuit DESCRIPTION The LM195/LM395 are fast, monolithic power integrated circuits with complete overload protection. These devices, which act as high gain power transistors, have included on the chip, current limiting, power limiting, and thermal overload 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 excess of 1.0A and can switch 40V in 500 ns. The inclusion of thermal limiting, a feature not easily available in discrete designs, provides virtually absolute protection against overload. Excessive power dissipation or inadequate heat sinking causes 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.
