Description

The H11AA1 optocoupler 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 that is detected by the phototransistor, causing it to conduct. This setup allows the H11AA1 to transmit signals across an isolation barrier while protecting sensitive components from high voltage or electrical noise.

Features

  • Electrical Isolation: Provides isolation between input and output, typically up to 5000 VRMS, to protect low-voltage circuits from high voltage surges and noise.
  • Compact DIP-6 Package: The 6-pin DIP package is convenient for mounting on circuit boards and is widely used in various electronic applications.
  • High Current Transfer Ratio (CTR): Ensures effective signal transmission with a high degree of isolation.
  • Low Input Current Requirement: Operates with a low LED input current, making it energy-efficient.
  • TTL and CMOS Compatible: The phototransistor 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 by model and test conditions).
  • 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: Ideal for isolating signals in electronic circuits to prevent high voltage or noise from affecting low-voltage components.
  • Microcontroller Interfacing: Used to interface microcontrollers with high-voltage or noisy signals while providing protection.
  • Switching Power Supplies: Provides isolation in feedback circuits of switch-mode power supplies (SMPS).
  • Industrial Automation: Commonly used in control systems and industrial applications where isolation of multiple signals is required.
  • Data Communication: Provides isolation in data communication lines to protect against interference and signal degradation.
