SS14 SMD Schottky Diode Data

Key data for the SS14 1A 40V SMD Schottky diode including key electrical parameters, performance, features, outline, package type and many other key datasheet details.

The SS14 is an SMD 1A 40V Schottky diode. It is packaged in a DO214 style 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 silicon of the device structure to prevent unwanted early voltage breakdown. Without the guard ring, the internal electric fields in the region of the junction would be much greater and cause early breakdown reducing the reverse voltage level for the device.

the SS14 also offers low power losses, high efficiency and the low forward voltage drop synonymous with Schottky diodes.

The SS14 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, V_RRM	This is the maximum value of the short period peak reverse voltage that can be sustained.
Working peak reverse voltage, V_RWM	This is the maximum value of the continuous reverse voltage that can be applied to the diode.
DC blocking voltage, V_R	This is the maximum reverse DC voltage that should be applied across the diode.
RMS reverse voltage, V_R(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, I_F	This is the maximum forward current that can be sustained by the diode.
Average rectified current, I_F	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, I_FSM	This is the maximum surge current that can be handled - it should only be present for a short time.

Parameter	Explanation
Power dissipation, P_TOT	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 V_F	This parameter gives the forward voltage drop for a particular current passed through the diode.
Breakdown voltage V_BR	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 I_R	This is the current that flows under stated conditions when the diode is reverse biassed.
Diode capacitance C_D	The diode capacitance, C_D may also be referred to as the junction capacitance, C_J. 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 operational amplifier parameters that have been included in our list. There are others, but these help quantify the main elements of the performance of the regulator, but are normally deemed to be less important.

• Device marking

In view of the fact that the SS14 device is very small, it is not possible to put the complete part number on it. Instead of SS14, the device is marked with the code S4.
