Poor Man's LTFLU-1CH
« on: June 06, 2017, 08:55:40 pm »
D1 is emitter-collector junction of one of the transistors on a THAT300 (reverse breakdown = 5.4V)
Q2 is another one on the chip.

the remaining two can be used to implement die temperature sensor and a heater.

i have measured the reverse break-down on THAT300 npn transistors ca. 5.4V (+.65 = 5.95V) and pnp transistors ca. 8.1V (+.65 = 8.75V)
