Types1 Leaded: BZW04-…, P4KE…, BZW06-…, P6KE…, 1.5KE… , 5KP…; (400 to 5000 W) SMD: TGL34-… , TGL41-…, P4SMA…, P6SMB…, 1.5SMC… ; (150 to 1500 W, up to 550V!) Bridge Rectifiers Available as complete device but can also be formed by four single devices. 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.

Diotec Products for Power Supplies www.diotec.com 06/2007 Single Rectifiers 1200 V to 24 kV EMI tests using burst pulses up to 2 kV are a big challenge for rectifiers used in 230 V power supplies. 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.

Datasheets see www.diotec.com, “Part search”. Diotec Products for Power Supplies www.diotec.com 06/2007 Flyback Converter Available as single device on request Clamping Network: TVS-/Fast-Diode Necessary for three reasons: Leakage inductance of the transformer causes voltage spikes during turn-off of the switch. 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.

Diotec Products for Power Supplies www.diotec.com 06/2007 Voltage Regulation Unregulated DC voltage Regulated DC voltage Zenerdiodes for simple voltage regulation A simple method to provide stabilized voltages from an unregulated voltage source. The resistor has to be choosen so that maximum allowable zener current IZmax (see datasheet) at the maximum occuring input voltage and at no load at the output is not exceeded. If voltage source is formed by a transformer, the series resistance of the windings may be enough to provide this resistor. Power dissipation of below devices ranges up to 5 W (leaded) and 3 W (SMD) respectively. For higher power needs series connection of zenerdiodes can be used. Tolerance is graded to E24 standard (approximately +/- 5%), if tighter limits are required parts with +/- 2% tolerance are available on request.

Special diodes (on request) offer beside low forward voltage drop also low leakage currents.
