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.

• Further details

The 1N5402 can be used in a large number of different applications, especially as it has a 3 amp current capability.

The diode is ideal for use as a rectifier diode in power supplies, inverters, converters and as well as in many other areas where high current capacity discrete diode many be required.

Another example where the 1N5402 may be used is as a reverse polarity protection diode where a it would be included in the supply line to prevent damage should the equipment be connected with the incorrect polarity.

• Reverse voltage ratings

When designing a circuit using a rectifier, one of the key parameters is that of the reverse voltage that the diode can withstand - n the ase of the 1N5402, it is 200V.

It is important to ensure that the circuit has a sufficient capability to withstand the voltages it might experience.

The reverse voltage, V_R depends not only on the voltages present within the circuit, but also the circuit configuration used.

The summary below provides a useful insight into what might be required.

It is also worth remembering that the rating for the diode should also include a general margin so that it is not run at the top of its rating - often a figure of 60 - 70% is a standard for industry.

In addition to this it is also necessary for the diode to accommodate any transients that may be encountered. These often occur when systems are connected mains of line power. Any lightning or switching spikes can propagate along the power lines and appear at the input of equipment.
