Overview
The SFH6319T is a high-speed optocoupler manufactured by Vishay Semiconductor Opto Division, featuring a single channel with a phototransistor output that includes a base connection. It supports data rates up to 100 kb/s and provides an isolation voltage of 4000 Vrms. The device operates within a temperature range of -55°C to +100°C and is housed in an 8-SOIC surface-mount package.
Feature Summary
- Integrates a phototransistor output with a dedicated base terminal for enhanced switching speed control and noise immunity.
- Delivers high gain characteristics suitable for low input current applications while maintaining fast signal transmission.
- Provides robust electrical isolation rated at 4000 Vrms between input and output circuits.
Applications
- Industrial communication interfaces requiring galvanic isolation
- Signal transmission in noisy electromagnetic environments
- Low-power logic interface circuits
Procurement Notes
Verify the specific suffix code against official Vishay documentation to confirm pinout configuration and packaging type. Ensure the selected variant matches the required operating temperature range and isolation voltage specifications for the target application environment.
Selection Notes
Select this component when a single-channel isolator with base-driven output is required for improved performance over standard phototransistor outputs. Consider the 100 kb/s data rate limit and the 4000 Vrms isolation barrier when designing circuit topologies.
Part Context
This part belongs to the Vishay SFH63 series of high-speed optocouplers. It is designed for applications demanding reliable signal transfer across isolated boundaries with minimal propagation delay. The series utilizes advanced LED and photodetector technologies to achieve high CTR and speed.
Replacement Considerations
Direct substitutes must match the 8-SOIC package, single-channel configuration, and base-connected phototransistor output. Verify compatibility with 4000 Vrms isolation and similar data rate capabilities before integration.
