Overview
The onsemi H11A1TVM is a single-channel optocoupler featuring an aluminum gallium arsenide infrared LED coupled to a silicon phototransistor. It utilizes a 6-pin dual in-line package (DIP) with a 0.400-inch width for through-hole mounting. The device provides electrical isolation of 4170Vrms and supports a maximum forward current of 60mA. It operates within a temperature range of -40°C to +100°C, ensuring reliable signal transmission across isolated circuits.
Feature Summary
- Integrates an infrared LED with a silicon phototransistor for efficient optical coupling
- Provides high-voltage electrical isolation between input and output circuits
- Designed for through-hole installation in standard 6-pin DIP configurations
Applications
- Industrial control systems requiring circuit isolation
- Power supply feedback loops for voltage regulation
- Signal interfacing between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix 'TVM' corresponds to the tube packaging format rather than tape and reel variants. Confirm that the 4170Vrms isolation rating meets the safety requirements of the target application environment. Ensure the operating temperature range aligns with the thermal constraints of the final assembly.
Selection Notes
Select this component when a robust transistor output is required for digital switching applications. Consider the 60mA maximum forward current limit for drive circuit design. Evaluate the 4170Vrms isolation barrier against system safety standards. Compare propagation delays if high-speed data transfer is necessary for the interface.
Part Context
This part belongs to the H11A series of general-purpose optocouplers from onsemi. The series is characterized by its compatibility with standard DIP footprints and widespread use in legacy and modern industrial designs. It serves as a fundamental building block for galvanic isolation in electronic systems.
Replacement Considerations
Direct substitutes include other H11A series variants such as H11A1M or H11A1SR2M, depending on the required packaging type. Cross-reference pinouts and isolation voltages to ensure mechanical and electrical compatibility during replacement.
