(a) Soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead. (b) Please be sure that the temperature of the package would not be heated over 100°C. Data Sheet PN10744EJ02V0DS 15 PS9302L (4) Cautions • Fluxes Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent. 2. Cautions regarding noise Be aware that when voltage is applied suddenly between the photocoupler’s input and output at startup, the output transistor may enter the on state, even if the voltage is within the absolute maximum ratings. USAGE CAUTIONS 1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static electricity when handling. 2. Board designing (1) By-pass capacitor of more than 0.1 μF is used between VCC and GND near device. Also, ensure that the distance between the leads of the photocoupler and capacitor is no more than 10 mm. (2) In older to avoid malfunctions and characteristics degradation, IGBT collector or emitter traces should not be closed to the LED input. (3) Pin 4 (which is an NC*1 pin) can either be connected directly to the GND pin on the LED side or left open. Unconnected pins should not be used as a bypass for signals or for any other similar purpose because this may degrade the internal noise environment of the device. *1 NC: Non-Connection (No Connection) 3. Make sure the rise/fall time of the forward current is 0.5 μs or less. 4. In order to avoid malfunctions, make sure the rise/fall slope of the supply voltage is 3 V/μs or less. 5. Avoid storage at a high temperature and high humidity. 16 Data Sheet PN10744EJ02V0DS PS9302L SPECIFICATION OF VDE MARKS LICENSE DOCUMENT Parameter Climatic test class (IEC 60068-1/DIN EN 60068-1) Dielectric strength maximum operating isolation voltage Test voltage (partial discharge test, procedure a for type test and random test) Upr = 1.5 × UIORM, Pd < 5 pC Test voltage (partial discharge test, procedure b for all devices) Upr = 1.875 × UIORM, Pd < 5 pC Highest permissible overvoltage Degree of pollution (DIN EN 60664-1 VDE0110 Part 1) Comparative tracking index (IEC 60112/DIN EN 60112 (VDE 0303 Part 11)) Material group (DIN EN 60664-1 VDE0110 Part 1) Storage temperature range Operating temperature range Isolation resistance, minimum value VIO = 500 V dc at TA = 25°C VIO = 500 V dc at TA MAX. at least 100°C Safety maximum ratings (maximum permissible in case of fault, see thermal derating curve) Package temperature Current (input current IF, Psi = 0) Power (output or total power dissipation) Isolation resistance VIO = 500 V dc at TA = Tsi Ris MIN. 10 9 Symbol Spec. 55/100/21 Unit UIORM Upr 1 130 1 695 Vpeak Vpeak Upr 2 119 Vpeak UTR 8 000 2 Vpeak CTI 175 III a Tstg TA –55 to +125 –40 to +100 °C °C Ω Ω Ris MIN.
