Aplication notes from TIP 31C

[nando]

Hi,

I need very much information about TIP 31C transistor for aplication in high volatage circuits. I need amplifier pulses from 0-5 v to 0-160 v

One caution about the TIP series. It was originated by Texas Instruments and then later copied by Motorola, now ON Semiconductor. Although the data sheets were essentially the same, two samples of the TIP29C from these two companies parametrically (Icbo, Vceo and beta) met all of their minimum / maximum specifications okay, but they differed from each other like night and day in terms of margins of safety to those specifications! The cautionary note: Be sure to test the parts from the vendor you intend to purchase from in your actual circuits and be sure to design your circuits EVER so conservatively!!

Good luck.
