SS13 SMD Schottky Diode Data
Key data for the SS13 SMD Schottky diode including key electrical parameters, performance, features, outline, package type and many other key datasheet details.
The SS13 is an SMD 1A 30V Schottky diode housed in a low profile DO214 surface mount package for automated placement onto a printed circuit board. The device has two connections, one at either end that are bet around under the device to make contact with the solder on the PCB pads.
The diode features a guard ring in the actual device structure to prevent unwanted early voltage breakdown.
the SS13 also offers low power losses, high efficiency and the low forward voltage drop synonymous with Schottky diodes.
The SS13 is one of a series of diodes, SS12 - SS16 offering various levels of maximum reverse voltage.

Explanation of major diode parameters
| Parameter | Explanation |
|---|---|
| Repetitive peak reverse voltage, VRRM | This is the maximum value of the short period peak reverse voltage that can be sustained. |
| Working peak reverse voltage, VRWM | This is the maximum value of the continuous reverse voltage that can be applied to the diode. |
| DC blocking voltage, VR | This is the maximum reverse DC voltage that should be applied across the diode. |
| RMS reverse voltage, VR(RMS) | As many AC waveforms are quoted in RMS, this is the maximum reverse voltage that can be sustained where the voltage is expressed in terms of its RMS value. |
| Forward continuous current, IF | This is the maximum forward current that can be sustained by the diode. |
| Average rectified current, IF | This is the maximum average current value that can be handled by the diode. The parameter often states the load as this will affect the operation of the diode. |
| Non-repetitive forward surge current, IFSM | This is the maximum surge current that can be handled - it should only be present for a short time. |
| Parameter | Explanation |
|---|---|
| Power dissipation, PTOT | The maximum power dissipation that can be sustained within the device. |
| Junction temperature (°C) | This is the maximum temperature of the PN junction that can be sustained. Remember that the junction temperature can be much higher than the ambient temperature of the equipment. |
| Forward voltage VF | This parameter gives the forward voltage drop for a particular current passed through the diode. |
| Breakdown voltage VBR | This is the minimum voltage at which the diode may breakdown. If the current is not limited it will lead to the destruction of the device. |
| Leakage current IR | This is the current that flows under stated conditions when the diode is reverse biassed. |
| Diode capacitance CD | The diode capacitance, CD may also be referred to as the junction capacitance, CJ. All diodes have a certain capacitance across the PN junction. The value will be stated for a given reverse voltage. |
| Reverse recovery time | If a diode is initially driven in forward bias, and the polarity suddenly switches to reverse bias, the diode will still remain conducting for some time. The reverse recovery time is the time required for conduction to settle into the reverse bias state. |
These are the main Schottky diode parameters that have been included in our list. There are others, but these help quantify the main elements of the performance of the diode.
Please note, that the data given is the best estimate we can give within a tabulated summary of this nature. Parameters also vary between manufacturers. Electronics Notes cannot accept any responsibility for errors, inaccuracies, etc, although we do endevaour to ensure the data is as accurate as possible.

• Device marking
In view of the fact that the SS13 device is very small, it is not possible to put the complete part number on it. Instead of SS13, the device is marked with the marking code S3.
