Overview
The SFH628A-2X016 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and provides 5300 Vrms galvanic isolation. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 55 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The forward voltage is typically 1.1 V at a forward current of 50 mA. The current transfer ratio ranges from 63% to 200%. Switching characteristics include a rise time of 3.5 µs and a fall time of 5 µs. It is housed in a 4-DIP package.
Feature Summary
- Provides high-voltage galvanic isolation for signal transmission between isolated circuits.
- Utilizes an NPN phototransistor output topology for reliable switching applications.
- Designed for through-hole mounting in standard DIP-4 packages.
Applications
- General-purpose digital signal isolation
- Microcontroller interface circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix X016 against the official Vishay datasheet to confirm packaging and binning details. Ensure the procurement channel sources genuine components with traceable documentation. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit products. Confirm RoHS compliance status as indicated in the latest product specifications.
Selection Notes
Select this component when high isolation voltage is required in a through-hole DIP package. Compare the 63-200% CTR range against circuit requirements for adequate noise margin. Evaluate the 55 V collector-emitter voltage limit against load conditions. Consider the 3.5 µs rise time for compatibility with target signal frequencies.
Part Context
This component belongs to the SFH628A series of transistor output optocouplers. The series offers various current transfer ratio grades and packaging options. The SFH628A-2X016 specifically denotes a particular CTR bin and tube packaging configuration within the broader Vishay optoelectronics portfolio designed for industrial and consumer electronics.
Replacement Considerations
Check for direct pin-compatible substitutes such as the SFH628A-3 or SFH628A-4 variants if different CTR bins are acceptable. Verify that alternative parts maintain the same 5300 Vrms isolation rating and DIP-4 footprint. Ensure replacement devices meet the same thermal and electrical specifications.
