Description

The H11A1 consists of an infrared light-emitting diode (LED) on the input side and a phototransistor on the output side. When the LED is forward biased, it emits infrared light, which is detected by the phototransistor. This causes the phototransistor to conduct, effectively transmitting the signal from the input to the output while maintaining electrical isolation between the two sides.

Features

  • Electrical Isolation: Provides isolation between the input and output, typically rated up to 5000 VRMS, ensuring protection of sensitive circuits from high voltage and electrical noise.
  • Compact DIP-6 Package: Housed in a 6-pin DIP package, making it easy to integrate into circuit boards.
  • High Current Transfer Ratio (CTR): Ensures effective signal transmission with a high degree of isolation.
  • Low Input Current Requirement: Operates efficiently with a low LED input current.
  • TTL and CMOS Compatible: The output is compatible with TTL and CMOS logic levels, making it versatile for digital applications.
  • Open-Collector Output: Allows for flexible interfacing with external circuits and components.

Specifications

  • Input LED Forward Voltage: Typically 1.2V (maximum 1.4V) at 20mA forward current.
  • Input LED Reverse Voltage: Maximum 6V.
  • Isolation Voltage: 5000 VRMS.
  • Current Transfer Ratio (CTR): Typically 50% to 600% at IF = 10mA, VCE = 5V (varies with different models).
  • Collector-Emitter Voltage (VCEO): Maximum 70V.
  • Collector Current (IC): Maximum 50mA.
  • Collector-Emitter Saturation Voltage (VCE(sat)): Maximum 0.3V at IC = 2mA, IF = 10mA.
  • Response Time:
    • Rise Time (tr): Typically 3µs.
    • Fall Time (tf): Typically 5µs.
  • Operating Temperature Range: -55°C to +100°C.

Applications

  • Signal Isolation: Provides electrical isolation in various applications, protecting low-voltage circuits from high voltage or noise.
  • Microcontroller Interfacing: Isolates microcontrollers from high-voltage components to ensure safe operation.
  • Switching Power Supplies: Used in feedback loops of switch-mode power supplies (SMPS) to transmit signals while maintaining isolation.
  • Industrial Control: Suitable for isolating control signals in industrial automation and control systems.
  • Data Communication: Provides isolation and protection in data communication interfaces.
