SFH6206-1 Equivalent & Substitute Parts

Part Overview

The SFH6206-1 is a single-channel optoisolator with transistor output manufactured by Vishay Semiconductor Opto Division. This component provides 5300Vrms isolation voltage in a 4-SMD surface mount package and is designed for AC/DC input applications requiring galvanic isolation. The part is active and in production with 3100 units currently in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, lead time considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFH6206-1 is determined by the following critical parameters:

• Isolation Voltage: Minimum 5000Vrms (SFH6206-1 specifies 5300Vrms; FOD814 series and LTV-814HS-TA1 provide 5000Vrms, which meets isolation requirements)
• Output Type: Transistor output configuration
• Number of Channels: Single channel
• Package / Case: 4-SMD, Gull Wing surface mount
• Input Type: AC/DC compatible
• Mounting Type: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

All identified substitute parts meet these core criteria. Variations in Current Transfer Ratio, turn-on/turn-off times, and output voltage/current ratings reflect different device grades within the optoisolator category but do not preclude substitution when application requirements are within the specified ranges of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the SFH6206-1.

FOD814AS, FOD814ASD, FOD814S, FOD814SD (onsemi): These parts provide 5000Vrms isolation with identical 4-SMD package configuration. FOD814AS and FOD814ASD offer tighter Current Transfer Ratio specifications (50-150% @ 1mA). FOD814S and FOD814SD provide wider Current Transfer Ratio range (20-300% @ 1mA). All onsemi variants feature improved Vce saturation (200mV vs. 400mV) and extended operating temperature to 105°C. Packaging options include Tube (FOD814AS, FOD814S) and Cut Tape with Digi-Reel (FOD814ASD, FOD814SD).

LTV-814HS-TA1 (Lite-On Inc.): This part provides 5000Vrms isolation with 4-SMD package. Output voltage is limited to 35V (compared to 70V for other options) but supports higher output current (80mA vs. 50mA). Operating temperature range is -30°C to 100°C. Supplied in Tape & Reel packaging.

Selection should be based on specific application requirements for output voltage, current capacity, and operating temperature range, with all options meeting core isolation and package compatibility criteria.

Frequently Asked Questions (FAQ)

Q: Can FOD814 series parts directly replace the SFH6206-1?

A: Yes, within the constraints of your application. All FOD814 variants (FOD814AS, FOD814ASD, FOD814S, FOD814SD) share identical package geometry (4-SMD, Gull Wing), isolation voltage (5000Vrms meets the 5300Vrms requirement), and output configuration (transistor, single channel). Verify that your circuit design accommodates the lower maximum Vce saturation (200mV vs. 400mV) and confirm output voltage/current requirements are within 70V/50mA limits.

Q: What is the key difference between FOD814AS and FOD814S?

A: Both are onsemi FOD814 variants in identical packages. FOD814AS specifies Current Transfer Ratio of 50-150% @ 1mA, while FOD814S specifies 20-300% @ 1mA. FOD814AS provides tighter tolerance; FOD814S allows wider variation. Selection depends on whether your circuit requires controlled gain or can tolerate broader specifications.

Q: Is LTV-814HS-TA1 suitable as a substitute?

A: LTV-814HS-TA1 is compatible for package and isolation voltage but has two critical differences: maximum output voltage is 35V (vs. 70V for other options) and operating temperature minimum is -30°C (vs. -55°C for SFH6206-1 and FOD814 series). Use this part only if your application operates within -30°C to 100°C and requires maximum 35V output.

Q: What does the packaging designation mean (Tube vs. Cut Tape vs. Tape & Reel)?

A: Tube, Cut Tape (CT) & Digi-Reel, and Tape & Reel (TR) refer to supply formats. Tube packaging is suitable for lower-volume applications. Cut Tape and Tape & Reel are for automated assembly lines. All three formats contain electrically identical components; selection is based on manufacturing process requirements and order quantities.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SFH6206-1 and all listed substitutes (FOD814AS, FOD814ASD, FOD814S, FOD814SD, LTV-814HS-TA1) are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the significance of the 5000Vrms vs. 5300Vrms isolation voltage difference?

A: The SFH6206-1 specifies 5300Vrms isolation; substitute parts specify 5000Vrms. Both exceed typical industrial isolation requirements. If your design specifically requires 5300Vrms isolation margin, the SFH6206-1 provides additional headroom. If 5000Vrms meets your isolation specification, substitutes are functionally equivalent.
