Overview
The Vishay 4N35-691 is a single-channel optocoupler featuring an infrared LED and silicon NPN phototransistor. It provides electrical isolation with a test voltage of 5000 VRMS. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum forward current of 60 mA, a typical rise/fall time of 10 μs, and a collector-emitter voltage rating of 30 V. It is available in a 6-pin DIP package.
Feature Summary
- Integrates a gallium arsenide infrared LED with a silicon NPN phototransistor for signal transmission.
- Provides high-voltage isolation capability suitable for separating circuits.
Applications
- General-purpose digital signal isolation
- Microprocessor system interfacing
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix '691' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the required isolation voltage and thermal characteristics align with the target application's safety standards before finalizing procurement orders.
Selection Notes
Select this component when a standard single-channel transistor output optocoupler is required. Consider the 10 μs switching speed and 5000 VRMS isolation rating. Verify that the 6-pin DIP form factor fits the PCB layout constraints and that the operating temperature range meets environmental requirements.
Part Context
This part belongs to the widely used 4N35 series of optocouplers manufactured by Vishay Semiconductor Opto Division. The series is characterized by its robust isolation performance and compatibility with standard logic families. The 4N35-691 variant specifically denotes the commercial grade version packaged in a 6-pin dual in-line configuration.
Replacement Considerations
Generic equivalents such as the HCPL-2630 or PC123 may offer similar functionality but require verification of pinout and CTR specifications. Direct substitutes should be confirmed via official cross-reference lists from Vishay or authorized distributors to ensure electrical compatibility.
