2.0 De-rating Factor
A blocking voltage de-rating factor of 0.13% per °C is applicable to this device for Tj below 25°C.
3.0 ABCD Constants
These constants (applicable only over current range of VF characteristic in Figure 1) are the coefficients of
the expression for the forward characteristic given below:
VF = A + B ⋅ ln(I F ) + C ⋅ I F + D ⋅ I F
where IF = instantaneous forward current.
4.0 Reverse recovery ratings

5.0 Reverse Recovery Loss
The following procedure is recommended for use where it is necessary to include reverse recovery loss.
From waveforms of recovery current obtained from a high frequency shunt (see Note 1) and reverse
voltage present during recovery, an instantaneous reverse recovery loss waveform must be constructed.
Let the area under this waveform be E joules per pulse. A new sink temperature can then be evaluated
from:
TSINK = T j ( MAX ) − E ⋅ [k + f ⋅ RthJK ]
Where k = 0.2314 (°C/W)/s
E = Area under reverse loss waveform per pulse in joules (W.s.)
f = Rated frequency in Hz at the original sink temperature.
Rth(J-Hs) = d.c. thermal resistance (°C/W)
The total dissipation is now given by:
W( tot ) = W( original ) + E ⋅ f
NOTE 1 - Reverse Recovery Loss by Measurement
This device has a low reverse recovered charge and peak reverse recovery current. When measuring the
charge, care must be taken to ensure that:
(a) AC coupled devices such as current transformers are not affected by prior passage of high
amplitude forward current.
(b) A suitable, polarised, clipping circuit must be connected to the input of the measuring oscilloscope
to avoid overloading the internal amplifiers by the relatively high amplitude forward current signal.
(c) Measurement of reverse recovery waveform should be carried out with an appropriate critically
damped snubber, connected across diode anode to cathode. The formula used for the calculation of this
snubber is shown below:
R2 = 4 ⋅
Where:
Vr
CS ⋅ di dt
Vr = Commutating source voltage
CS = Snubber capacitance
R = Snubber resistance
6.0 Snubber Components
When selecting snubber components, care must be taken not to use excessively large values of snubber
capacitor or excessively small values of snubber resistor. Such excessive component values may lead to
device damage due to the large resultant values of snubber discharge current. If required, please consult
the factory for assistance.

− VT 0 + VT 0 + 4 ⋅ ff 2 ⋅ rT ⋅ WAV

2 ⋅ ff 2 ⋅ rT
Where VT0 = 1.24V, rT = 0.33mΩ
ff = form factor (normally unity for fast diode applications)
WAV =
∆T
Rth
∆T = T j ( MAX ) − Tk
7.2 Calculation of VF using ABCD Coefficients
The forward characteristic IF Vs VF, on page 6 is represented in two ways;
(i)
the well established VT0 and rT tangent used for rating purposes and
(ii)
a set of constants A, B, C, and D forming the coefficients of the representative equation for VF in
terms of IF given below:
VF = A + B ⋅ ln(I F ) + C ⋅ I F + D ⋅ I F
The constants, derived by curve fitting software, are given in this report for both hot and cold
characteristics. The resulting values for VF agree with the true device characteristic over a current range,
which is limited to that plotted.

10.0 Duty cycle lines
The 100% duty cycle is represented on all the ratings by a straight line. Other duties can be included as
parallel to the first.
