Overview
The SFH6156-1X001T is a single-channel optoisolator featuring a transistor output, manufactured by Vishay Semiconductor Opto Division. It provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. The device utilizes a 4-SMD鸥翼 (gull-wing) package for surface mount installation. Key electrical parameters include a maximum collector-emitter voltage of 70V, a continuous output current of 50mA per channel, and a typical forward voltage of 1.25V. The current transfer ratio ranges from 40% to 80% at a forward current of 10mA, with a maximum DC forward current of 60mA.
Feature Summary
- Integrates an aluminum gallium arsenide infrared emitting diode coupled to a silicon planar phototransistor detector
- Provides high insulation voltage capability suitable for electrically isolated signal transmission between circuits
- Features low coupling capacitance for improved noise immunity in sensitive applications
Applications
- Signal transmission between electrically isolated circuits
- General purpose digital communication interfaces requiring galvanic isolation
- Microcontroller input/output isolation in industrial control systems
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm the exact Current Transfer Ratio (CTR) binning and packaging configuration. Ensure that the procurement source provides valid RoHS compliance documentation consistent with the component's environmental specifications. Cross-reference the ordering part number with the manufacturer's latest product change notices to avoid discrepancies in lead frames or assembly origins.
Selection Notes
Select this component when a surface-mount solution with high isolation voltage is required for single-channel applications. Consider the CTR range of 40% to 80% for logic level compatibility and drive requirements. Evaluate the thermal operating range and saturation voltage characteristics to ensure suitability for the target circuit's power dissipation and switching speed constraints.
Part Context
This component belongs to the SFH6156 family of transistor-output optocouplers from Vishay. The family offers various CTR bins and packaging options, including through-hole and surface-mount configurations. The SFH6156-1X001T specifically denotes the surface-mount variant with defined electrical tolerances, sharing core architectural features with other members like the SFH6156-1T while differing in specific binning or packaging details.
Replacement Considerations
The VO615A-1X001 is listed as a recommended alternative by distributors, though it utilizes a DIP-4 through-hole package rather than SMD. Verify pinout compatibility and electrical parameter overlaps before substitution.
