Hi there.
I'm curios now with a choice of a pin-diode for a high power switch.
The power conditions are:
Also average power might be decreased down to 10 W, while peak power would be still 2.1 kW (it depends on quantity of pulses).
There are few point that confounding me:
Thank you in advance!
I'm curios now with a choice of a pin-diode for a high power switch.
The power conditions are:
- Ppeak = 1 kW;
- Pcw = 40 W;
- tpulse = 4 us;
- doble gaussian pulse
Also average power might be decreased down to 10 W, while peak power would be still 2.1 kW (it depends on quantity of pulses).
There are few point that confounding me:
- Which concrete power should be used for diode choice? I used to belive that in this case CW power shoud be compared with diode dissipation power through the well-known formulas. However in case of high duty cycle, I suppose, peak power becomes more relevant. Here I have a paradox: power strengh of a diode decrease with decrease of average power.
- Breakdown voltage. I also used to belive, that this parameter characterize a value of voltage, that diode can handle in a closed state. In other words, I should calculate voltage from the signal power through a diode resistance in a closed state. If it is true, again the question is, what type of powe should be used.
Thank you in advance!
