National LM195 power transistor is turned on and off once per second for flashing 12-V lamp. Current limiting in LM195 prevents high peak currents during turnon even though cold lamp can draw 8 times normal operating current. Current-limiting feature prolongs lamp life in flashing applications.-R.Dobkin, Fast IC Power Transistor with Thermal Protection, National Semiconductor, Santa Clara, CA, 1974, AN-110, p 5.
