Instructions for Use:

  1. Power Supply (VCC):

    • Ensure the supply voltage is within the range of 3.0V to 30.0V.
    • Avoid exceeding the maximum voltage to prevent damage.
  2. Forward Current (IF):

    • The forward current should be between 15mA and 30mA.
    • Higher currents can cause overheating and reduce the lifespan of the device.
  3. Output Current (IC):

    • The output current should not exceed 150mA to avoid damaging the output transistor.
    • For reliable operation, keep the current below 100mA.
  4. Input Trigger Level (VIL and VIH):

    • The input low level (VIL) should be between 1.4V and 1.6V.
    • The input high level (VIH) should be between 2.0V and 2.4V.
    • Ensure the input signal levels are within these ranges to avoid incorrect triggering.
  5. Propagation Delay Time (tPLH, tPHL):

    • The propagation delay time is typically 2.0渭s with a maximum of 4.0渭s.
    • This delay can affect the timing accuracy of your circuit, so ensure it is accounted for in your design.
  6. Temperature Considerations:

    • The storage temperature range is -40掳C to 110掳C.
    • The operating temperature range is -40掳C to 85掳C.
    • Ensure the device is used within these temperature limits to maintain reliability.
  7. Isolation Voltage (VIOM):

    • The isolation voltage is rated at 2500Vrms for 1 minute.
    • This ensures electrical isolation between the input and output sides.
  8. Insulation Resistance (RI):

    • The insulation resistance is at least 100M惟 at 500V and 25掳C.
    • This helps maintain the isolation integrity of the device.
  9. Leakage Current (IOL):

    • The leakage current should not exceed 1.0渭A at 5V and 25掳C.
    • Excessive leakage can affect the performance of sensitive circuits.
  10. Maximum Power Dissipation (PD):

    • The maximum power dissipation is 625mW at 25掳C.
    • Ensure proper heat dissipation if the device is expected to operate near this limit.

By following these parameters and instructions, you can ensure the reliable and efficient operation of the TLP281GB optocoupler in your application.
