Bridge Rectifiers Available as complete device but can also be formed by four single devices (see next page). Recommended values for protective resistor Rt and load capacitor CL are given within the datasheet. Rt includes also series resistance of transformer and leads, at small powers an additional device is therefore often not necessary.

Instead of switching two devices in series, single rectifiers having 1200 to 2000 V can be used. Special high voltage rectifiers allow usage at medium to high voltages.

At 230 VRMS mains, minimum a 600 V type should be used, at 110 VRMS a 400 V type.

Current commutation from primary to secondary side needs a small time during that voltage across the switch is rising to high levels. If output voltage is not controlled and there is no load at the output, voltage may increase until rectifier diode breaks down.

Lowest thermal resistance is achieved by bending the leads in a radial way, see picture in the middle. Diotec offers the service to supply devices with leads already bent, please contact your local Diotec Sales Office or Diotec distributor for more information.
