Auxiliary Switch Diodes for Snubber
SARS01, SARS05
Data Sheet
Description
Package
The SARS01/05 is an auxiliary switch diode
especially designed for snubber circuits, which are used
in the primary sides of flyback switched-mode power
supplies.
Being capable of reducing the ringing voltage
generated at power MOSFET turn-off, the
SARS01/05-incorporated snubber circuits allow better
cross regulation of multiple outputs.
The SARS01/05 can also improve power supply
efficiency by partially transferring such ringing voltage
into the secondary side of a power supply unit.

Operational Comparison of Clamp Snubber
Circuits
Figure 16 shows a general clamp snubber circuit. In
the circuit, the surge voltage at tuning off a power
MOSFET is charged to CS through the surge absorb loop,
and is consumed by RS1 through the energy discharge
loop. All the consumed energy becomes loss in RS1. In
addition, the ringing of surge voltage results in poor
cross regulation of multi-outputs.
Figure 19 shows the clamp snubber circuit using the
SARS01/05. The surge voltage at tuning off a power
MOSFET is charged to CS through the surge absorb loop.
Since the reverse recovery time, trr, of the SARS01/05 is
a relatively long period, the energy charged to CS is
discharged to the reverse direction of the surge absorb
loop until CS voltage is equal to the flyback voltage.
Some discharged energy is transferred to secondary side.
Thus, the power supply efficiency improves.
In addition, the power supply using the SARS01/05
reduces the ringing voltage. Thus, the cross regulation of
multi-outputs can be improved.

Power Dissipation and Junction
Temperature Calculation
Figure 22 shows a typical application using the
SARS01/05. Figure 23 shows the operating waveforms
of the SARS01/05. The power dissipation of the
SARS01/05 is calculated as follows:
1) The waveforms of the SARS01/05 voltage, VSARS,
and the SARS01/05 current, ISARS, are measured in
actual application operation. VSARS × ISARS is
calculated by the math function of oscilloscope.
2) The each average energy (P1, P2…Pk) is measured at
period of each polarity of VSARS × ISARS (t1, t2,…tk) as
shown in Figure 22 by the automatic measurement
function of the oscilloscope.
3) The power dissipation of the SARS01/05, PSARS, is
calucultaed by Equation (1):
PSARS =
1
(|P × t1 | + |P2 × t 2 | + ⋯ |Pk × t k |)
T 1
(1)
A differential probe is recommended to use for the
measurement of VSARS. Please conform to the
oscilloscope manual about power dissipation
measurement including the delay compensation of probe.
In addition, by using the temperature of the SARS01/05
in actual application operation, the estimated junction
temperature of the SARS01/05 is calculated by Equation
(2). It should be enough lower than TJ of the absolute
maximum rating.
where:
TJ(SARS) is junction temperature of the SARS01/05,
TL is lead temperature of the SARS01/05, and
θJ-L is thermal resistance between junction to lead.

Parameter Setting of Snubber Circuit using

The temperature of the SARS01/05 and peripheral
components should be measured in actual application
operation.
The reference values of snubber circuit using the
SARS01/05 are as follows:
where:
PSARS is power dissipation of the SARS01/05,
T is switching cycle of power MOSFET (s), and
Pk is average energy of period tk (W).
TJ(SARS) = TL + θJ−L × PSARS (°C)

● CS
680 pF to 0.01 μF.
The voltage rating is selected according to the voltage
subtraced the input voltage from the peak of VDS.
● RS1
RS1 is the bias resistance to turn off the SARS01/05,
and is 100 kΩ to 1 MΩ.
Since a high voltage is applied to RS1 that has high
resistance, the following should be considered according
to the requirement of the application:
- Select a resistor designed for electromigration, or
- Connect more resistors in series so that the applied
voltages of individual resistors can be reduced.
The power rating of resistor should be selected from
the measurement of the effective current of RS1 based on
actual operation in the application.
● RS2
RS2 is the limited resistance in the energy discharging.
The value of 22 Ω to 220 Ω is connected to the
SARS01/05 in series.
The power rating of resistor should be selected from
the measurement of the effective current of RS2 based on
actual operation in the application.

(1)
Unless otherwise specified, the voltage rating of capacitor is 50 V or less and the power rating of resistor is 1/8 W or less.
Refers to a part that requires adjustment based on operation performance in an actual application.
(3)
High voltage is applied to this resistor that has high resistance. To meet your application requirements, it is required to select resistors designed for
electromigration, or to connect more resistors in series so that the applied voltages of individual resistors can be reduced.
