To find a sensible rcd combination, it's a tradeoff as to what amount of energy comes from the transformer primary as it shuts off, versus what voltage you wish to accumulate on the capacitor, versus the watt rating of the resistor. Voltage, vces volts (x50) for ipm:

9.2 the capacitor shall be equipped with discharge resistors that reduce the capacitor voltage to 50 volts in 5 minutes when disconnected from the source. Make sure the capacitor has a high voltage rating.

Be Careful Of The Capacitor’s Peak Current Rating, Which You Can Never Exceed, Even Momentarily.

The rating must be greater than the expected clamping voltage. 0.125, 0.25, 0.5, 1, or as specified. And i have not taken one apart.

Usually The Dv/Dt Rating Of A Diode Is Given In The Manufacturers Datasheet.

There are ac rated capacitors these should have a rms rating of at least teh ains voltage plus margins. For these applications, capacitors with a rated voltage of 1000v are recommended. The networks associated with the inductor and capacitor shown in figure i determine how energy is passed to the storage element and how the energy is removed from it all of the other

Once You Know Those, You Can Calculate The Snubber Capacitor (C Snub) And Resistor (R Snu B).

Capacitor parameter dc voltage class the maximum continuously applied dc voltage can be the rated dc voltage given in the data sheet to achieve the life expectancy. 3 kvac for 60 s climatic category : 385v and 400v are common dc ratings for 230v.

The Voltage Rating Of Fsdm311 Is 650V, According To The Datasheet.

Make sure the capacitor has a high voltage rating. It is not obvious from datasheets what actual voltage ratings are on the capacitors inside those snubber networks. There are two reasons for the excess of the voltage ratings:

The Configuration Shown In Figure 2A Can Only Act As A Voltage Clamp.

Almost none mention capacitor voltage, only capacitance. The wrong transformer design and/or the wrong snubber design. Ib) has inductors for energy storage.
