Ensure sufficient physical distance on your PCB between the input and output traces. This preserves the high-voltage isolation rating of the component.
Operating the device beyond these limits can cause permanent physical degradation or immediate component failure. All ratings are measured at an ambient temperature ( TAcap T sub cap A ) of 25掳C unless otherwise specified. Input (Emitter) 60 mA Reverse Voltage ( VRcap V sub cap R ): 6.0 V Power Dissipation ( PDcap P sub cap D ): 100 mW Output (Detector) Collector-Emitter Voltage ( VCEOcap V sub cap C cap E cap O end-sub ): 50 V Emitter-Collector Voltage ( VECOcap V sub cap E cap C cap O end-sub ): 7.0 V Collector Current ( ICcap I sub cap C ): 50 mA Power Dissipation ( PCcap P sub cap C ): 150 mW Total Component Isolation Test Voltage ( VISOcap V sub cap I cap S cap O end-sub ): 5300 VRMScap V sub cap R cap M cap S end-sub (1 Minute) Operating Temperature Range ( TAMBcap T sub cap A cap M cap B end-sub ): -55掳C to +100掳C Storage Temperature Range ( TSTGcap T sub cap S cap T cap G end-sub ): -55掳C to +150掳C Soldering Temperature (10 seconds): 260掳C Electrical Characteristics 1458 optocoupler datasheet

Due to its combination of fast response times and low power dissipation, the 1458 optocoupler series serves as a critical bridge in several topologies: Single Channel, High Speed Optocouplers Technical Data All ratings are measured at an ambient temperature
Operating the component beyond these limits can cause permanent damage to the device. These specifications are typically rated at an ambient temperature ( TAcap T sub cap A ) of 25掳C unless specified otherwise. -55掳C to +125掳C Operating Temperature Range: -40掳C to +85掳C Isolation Voltage ( VISOcap V sub cap I cap S cap O end-sub ): 3750 VRMScap V sub cap R cap M cap S end-sub VRMScap V sub cap R cap M cap S end-sub (1-minute rating, depending on suffix/manufacturer) Input Diode (Per Channel) Forward Current ( IFcap I sub cap F ): 25 mA Peak Forward Current ( IF,peakcap I sub cap F comma p e a k end-sub ): 50 mA (with brief pulse width) Reverse Voltage ( VRcap V sub cap R ): 5 V Output Detector (Per Channel) Output Current ( IOcap I sub cap O ): 8 mA Supply Voltage ( VCCcap V sub cap C cap C end-sub
