• In order to stabilize the power supply line, we recommend to locate a bypass capacitor CB (0.01µF or more)
between VCC and GND near photocoupler.
• In order to stabilize the detecting voltage of pin-C, we recommend to locate a capacitor CP (approximately
1 000pF) between pin-C and GND, and a resistor RC (approximately 1.0kΩ) between VCC and pin-C.
However, the rise time of the detection voltage at Pin-C varies along with the time constants of CP and RC.
So, please make sure the device works properly in actual conditions.
• For the diode D, which is located between pin-C and collector of IGBT, we recommend to use a diode that
has the withstand voltage characteristic equivalent to IGBT and also has little leak current.
• In order to prevent the failure mode or breakdown of pin-C from VCE variation of IGBT, we recommend to
locate a resistor R2 (approximately 10kΩ) and a diode D1 at near pin-C, and a resistor R3 (approximately
50kΩ) and a diode D2 at between pin-C and GND.
This application circuit shows the general example of a circuit, and is not a design guarantee
for right operation.

4. Judgement and processing by the microcomputer
In the case of instantaneous shortcircuit, run continues.
At fault, input to the photocoupler is cut off, and IGBT is

■ Design Considerations
● Notes about static electricity
Transistor of detector side in bipolar configuration may be damaged by static electricity due to its minute design.
When handling these devices, general countermeasure against static electricity should be taken to avoid
breakdown of devices or degradation of characteristics.
● Design guide
In order to stabilize power supply line, we should certainly recommend to connect a by-pass capacitor of
0.01µF or more between VCC and GND near the device.
We recommed to use approximately 1 000pF of capacitor between C-pin and GND in order to prevent miss
opration by noise.
In the case that capacitor is used approximately 1kΩ of resistance shall be recommended to use between
V CC and C-pin However, the rise time of C-pin shall be changed by time constant of added CR, so that
please use this device after confirmation.
In case that some sudden big noise caused by voltage variation is provided between primary and secondary
terminals of photocoupler some current caused by it is floating capacitance may be generated and result in
false operation since current may go through LED or current may change.
If the photocoupler may be used under the circumstances where noise will be generated we recommend to
use the bypass capacitors at the both ends of LED.
The detector which is used in this device, has parasitic diode between each pins and GND.
There are cases that miss operation or destruction possibly may be occurred if electric potential of any pin
becomes below GND level even for instant.
Therefore it shall be recommended to design the circuit that electric potential of any pin does not become
below GND level.
This product is not designed against irradiation and incorporates non-coherent LED.

● Degradation
In general, the emission of the LED used in photocouplers will degrade over time.
In the case of long term operation, please take the general LED degradation (50% degradation over 5years)
into the design consideration.
Please decide the input current which become 2times of MAX. IFLH.

Flow Soldering :
Due to SHARP's double transfer mold construction submersion in flow solder bath is allowed under the below
listed guidelines.
Flow soldering should be completed below 260˚C and within 10s.
Preheating is within the bounds of 100 to 150˚C and 30 to 80s.
Please don't solder more than twice.
Hand soldering
Hand soldering should be completed within 3s when the point of solder iron is below 400˚C.
Please don't solder more than twice.
Other notices
Please test the soldering method in actual condition and make sure the soldering works fine, since the impact
on the junction between the device and PCB varies depending on the tooling and soldering conditions.
