Description

The TPA series are TRISIL devices especially designed for protecting sensitive telecommunication equipment against lightning and transient voltages induced by AC power lines.They are available in the DO-15 axial package. TRISIL devices provide bidirectional protection by crowbar action. Their characteristic response to transient overvoltages makes them particularly suited to protect voltage sensitive telecommunication equipment.It has four unique features: The first one is bidirectional crowbar protection. The second one is voltage rating is from 62 V to 270 V. The third one is holding current which is 150 mA min. The last one is repetitive pulse current which is 50 A,10/1000 us.

There are some absolute maximum ratings about TPA series  when Tamb is 25. Power dissipation on infinite heatsink(P)(Tamb = 50 °C) is 1.7 W. Peak pulse current(IPP )(10/1000 us) is 50 A or is 100 A(8/20 ms). Non repetitive surge peak on-state current(ITSM)(tp = 20 ms) is 30 A. I2t value for fusing(I2t )(tp = 20 ms) is 9 A2s.Critical rate of rise of off-state voltage(dV/dt, VRM) is 5 kV/ms.Storage temperature range(Tstg) is - 55°C to + 150°C.Maximum junction temperature(Tj) is 150°C.Otherwise,there are some thermal resistances about it. Junction to leads (Llead = 10mm)(Rth (j-l)) is 60 °C/W.Junction to ambient on printed circuit (Llead = 10 mm)(Rth (j-a))is 100 °C/W.

All the information above is just a simple introduction to  TPA series , if you are interested in it or want to know more about it, please pay more attention to our web and you can find more detailed information about it!Thanks for your attention!
