Overview
The H11A1W is a general-purpose, single-channel phototransistor optocoupler manufactured by Fairchild Semiconductor. It integrates a gallium arsenide infrared emitting diode with a silicon phototransistor within a 6-pin dual in-line package (DIP). The device provides electrical isolation between input and output circuits, featuring a maximum insulation voltage of 7500 Vrms. It operates over an extended temperature range from -40 °C to 100 °C, supporting through-hole mounting for robust circuit integration.
Feature Summary
- Integrates a gallium arsenide infrared LED driver with a silicon phototransistor for signal transmission
- Provides high-voltage electrical isolation between input and output circuits
- Designed for reliable digital signal transmission with high sensitivity photocurrent output
Applications
- Power supply regulators
- Digital logic inputs
- Microprocessor inputs
Procurement Notes
Verify the specific suffix 'W' against official Fairchild documentation to confirm package material or variant details, as standard datasheets often reference the 'M' suffix for white packages. Ensure compliance requirements such as RoHS and REACH are confirmed via the manufacturer's current certification documents before procurement.
Selection Notes
Select this component when a general-purpose, single-channel isolation solution is required for low-speed digital applications. Consider the DIP-6 package constraints and the operating temperature limits. Verify that the collector-emitter breakdown voltage and current transfer ratio meet the specific circuit design requirements compared to other members of the H11A series.
Part Context
The H11A1W belongs to the H11AXM family of general-purpose 6-pin phototransistor optocouplers produced by Fairchild Semiconductor. This series is widely recognized for its industry-standard pinout and compatibility with various isolation applications. The part utilizes a transistor output configuration, distinguishing it from photodiode or triac output variants within the broader optocoupler market.
Replacement Considerations
Direct substitutes include H11A1M and H11A1L. Cross-references may also include 4N25M and MOC8204, provided pinouts and electrical characteristics align with the application requirements.
