Overview
The SFH615A-3X008T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a surface-mount SMD-4 package. The device provides high isolation with a rated voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a power dissipation of 150 mW. The forward current is rated at 60 mA with a forward voltage of 1.65 V. The current transfer ratio ranges from 100% to 200%. Operating temperatures span from -55°C to +100°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
- Designed for surface-mount assembly in compact electronic systems requiring reliable signal transmission.
- Ensures safety compliance through high insulation voltage ratings suitable for industrial applications.
Applications
- Industrial control systems requiring isolated signal interfaces
- Power supply feedback loops for voltage regulation
- Communication equipment needing noise immunity
Procurement Notes
Verify the specific suffix X008T corresponds to the required tape-and-reel packaging configuration. Confirm that the SMD-4 footprint matches the target PCB design constraints. Ensure the manufacturer designation aligns with Vishay Semiconductor Opto Division specifications for quality assurance.
Selection Notes
Choose this component when surface-mount technology is mandatory for space-constrained designs. Select based on the requirement for a 5300 Vrms isolation barrier and NPN phototransistor output characteristics. Consider the operating temperature range and current transfer ratio requirements for the specific application environment.
Part Context
This part belongs to the SFH615 series of transistor output optocouplers. It shares functional similarities with through-hole variants like SFH615A-3 but differs in package type. The series is designed for general-purpose isolation tasks within Vishay's optoelectronics portfolio.
Replacement Considerations
SFH615A-3 serves as a direct through-hole alternative with identical electrical characteristics. VO615A-3 is another equivalent option available in DIP-4 packaging. Verify pin compatibility and thermal performance when substituting.
