Overview
The SFH6325-X017T is a dual-channel optocoupler featuring phototransistor outputs, designed for electrical isolation between circuits. It integrates an infrared LED and two phototransistors in an SMD-8 package. Key parameters include a 5300 Vrms isolation voltage, 10 Mb/s data rate capability, and 2 channels. The forward current is 25 mA with a typical forward voltage of 1.33 V. Output characteristics specify a maximum collector-emitter voltage of 25 V and output current of 8 mA per channel. Turn-on/turn-off times are typically 300 ns and 600 ns respectively. Operating temperature ranges from -55°C to +100°C.
Feature Summary
- Provides galvanic isolation via infrared LED and phototransistor pairs
- Dual-channel configuration for simultaneous signal transmission
- High insulation voltage rating for safety-critical applications
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical isolation between system components
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and date codes against current production status. Check for end-of-life notifications as availability may be limited. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Validate pinout compatibility before integration into existing PCB layouts.
Selection Notes
Consider the dual-channel requirement when selecting this component over single-channel alternatives. Evaluate the 5300 Vrms isolation voltage against system safety standards. Assess the 25 V output voltage limit for compatibility with downstream logic levels. Review thermal management requirements given the operating temperature range and power dissipation constraints.
Part Context
This part belongs to Vishay's high-speed optocoupler family, specifically designed for applications requiring reliable electrical isolation. The SFH6325 variant offers dual-channel functionality within a compact surface-mount package, suitable for space-constrained designs. It complements Vishay's broader portfolio of optoelectronic isolation solutions.
Replacement Considerations
SFH6325-X009T is listed as a parameter-equivalent substitute. Verify pinout and electrical specifications match before substitution. HCPL series parts may offer similar performance but require separate validation.
