Larger diodes will dissipate more heat.

Diode current rating chart. The european systemes diode code identification consists of an alphanumeric code as per below. Note the diodes packaging or case style. Ideally this figure would be zero.

1 two letters and three figures 2 three letters and two figures the first naming method is for general purpose diodes and the second option is for special purpose diodes. This data sheet shows the ratings of different diodes which include zener voltage the tolerance range of zener voltage zener current limits the maximum power dissipation maximum operating temperature maximum. Maximum forward voltage vf usually specified at the diodes rated forward current.

As shown in the above figure. The diode providing no opposition whatsoever to forward current. Ideally this figure would be zero.

Maximum ratings and electrical characteristics at t a 250c unless otherwise specified single phase half wave 60hz resistive or inductive load. The diode providing no opposition whatsoever to forward current. If the circuit uses pulsed current instead of dc also look at the peak current forward current rating specification in the catalog.

Therefore the average forward current through the diode is lsvo vo637 1697 0540 a. Similarly the continuous current rating of a diode or a thyristor or an igbt is calcul ated from the basic equation of temperature rise. Zener diode ratings the word ratings means the various information about that particular device is given on the name plate of the device or data sheet provided by the manufacturer.

For capacitive load derate current by 20. The rating is the continuous current limit of the diode. For example if you have a 2 a power supply but are only using a load that draws 1 a you may be fine with the 1n1007.

The least expensive diode having ratings adequate for the peak inverse voltage and average forward current values we calculated is the one costing 200. Rthjc is the maximum value of internal junction to case thermal resistance and tc is the case temperature. As with the other ratings youll want to allow at least a 20 percent safety margin.

If you use these with a 2 a or 6 a power supply makes no difference its the amount of load current that flows that is the limitation.
