Overview
The SFH615A-2 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and utilizes a GaAs infrared diode for signal transmission. The device provides high isolation voltage of 5300 Vrms and supports through-hole mounting in a PDIP-4 package. Key electrical parameters include a minimum collector-emitter voltage of 70 V, maximum collector current of 50 mA, and a forward current rating of 60 mA. The current transfer ratio ranges from 63% to 125%, with typical rise and fall times of 3 μs and 14 μs respectively.
Feature Summary
- High isolation voltage capability of 5300 Vrms for safe circuit separation
- End-stackable design with standard 2.54 mm lead spacing for compact assembly
- Utilizes GaAs infrared diode for efficient signal coupling
Applications
- Signal transmission between electrically separated circuits
- General purpose digital isolation applications
- Industrial control system interfacing
Procurement Notes
Verify the specific suffix code (e.g., -2X016) against official datasheets to confirm exact current transfer ratio and packaging configuration. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with surface-mount variants or different transfer ratio options within the same family.
Selection Notes
Select this component when through-hole mounting is required for robust mechanical connection. Choose based on the need for high isolation voltage exceeding standard low-voltage couplers. Consider the specific current transfer ratio requirements for the application logic levels. Verify that the operating temperature range meets the environmental conditions of the target equipment.
Part Context
This component belongs to the SFH615A series of transistor output optocouplers. The series offers various transfer ratios and packaging options including surface mount and through-hole configurations. The SFH615A-2 specifically denotes the through-hole PDIP variant. It is designed for general-purpose isolation where moderate speed and high reliability are necessary.
Replacement Considerations
Public confirmed substitutes include VO615A-2X019T and SFH6156-2. Verify pinout compatibility and electrical parameter equivalence before substitution.
