Product details
Overview
VOW2611-X017T from Vishay Semiconductors is a high-speed optocoupler with 10 MBd data rate, strobable open-drain output, and guaranteed common-mode transient immunity of 10 kV/μs. It features LVTTL/LVCMOS compatibility, operates from 4.5 V to 5.5 V supply, and delivers propagation delays as low as 25 ns (tPLH/tPHL) for digital isolation in industrial power supplies and microprocessor interfaces.
For engineers reviewing the VOW2611-X017T datasheet, VOW2611-X017T pinout, VOW2611-X017T application, or VOW2611-X017T equivalent, key selection criteria include CMTI ≥10 kV/μs, isolation voltage rating of 5000 VRMS, open-drain output configuration, operating temperature range of –40 °C to +100 °C, and SMD-8 widebody package with 10 mm creepage/clearance.
Technical Context
The VOW2611-X017T integrates a high-efficiency GaAs LED input stage coupled to a monolithic photodetector logic gate with strobe-enabled control. Its internal shield ensures robust noise rejection in high dv/dt environments such as motor drives and isolated DC-DC converters.
It supports positive-logic truth table operation with enable-controlled output latching, offers 1 pF input-to-output capacitance for minimal signal coupling, and maintains stable switching performance across –40 °C to +100 °C with typical pulse width distortion under 10 ns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACPL-K37T | Higher CMTI (25 kV/μs), same 10 MBd rate, but requires external VDD bypass and has different enable logic polarity | Better suited for ultra-noisy motor drive gate driver feedback where CMTI margin is critical | Select ACPL-K37T only if system-level CMTI requirement exceeds 15 kV/μs and layout allows polarity-aware enable routing |
| HCPL-0723 | Same SMD-8 package and pinout, but lower data rate (5 MBd) and no strobe enable function | Applicable where cost sensitivity outweighs need for strobe control and full 10 MBd bandwidth | Choose HCPL-0723 for legacy designs requiring drop-in replacement without redesigning enable logic or timing constraints |
Compared with VOW2611-X017T, ACPL-K37T provides superior noise immunity but demands careful enable signal inversion and tighter layout controls, while HCPL-0723 sacrifices speed and strobe capability for broader availability and lower unit cost in non-critical timing applications.

FAQ
What is the maximum recommended forward current for the VOW2611-X017T LED input?
The absolute maximum forward current for the VOW2611-X017T LED input is 20 mA, but the recommended operating condition specifies 5–15 mA for reliable long-term performance. Operating at 7.5 mA achieves optimal balance between speed (tPLH/tPHL ≈ 50 ns typ.) and LED lifetime. Exceeding 15 mA continuously may accelerate degradation without improving switching performance.
Does the VOW2611-X017T require an external pull-up resistor on the VO pin?
Yes, the VOW2611-X017T features an open-drain VO output and requires an external pull-up resistor to VCC. The recommended value ranges from 330 Ω to 4000 Ω depending on speed and fanout requirements; 1 kΩ is typical for driving up to five TTL loads while maintaining <100 ns propagation delay. No pull-up is needed on the VE pin, which has internal biasing.
What safety certifications does the VOW2611-X017T hold?
The VOW2611-X017T is certified to UL1577 (5000 VRMS isolation), cUL, and DIN EN 60747-5-5 (VDE 0884-5) with option 1, providing reinforced insulation qualification. It meets creepage and clearance distances ≥10 mm and has a comparative tracking index (CTI) of 175, making it suitable for pollution degree 2 environments per IEC 60664-1.
Can the VOW2611-X017T operate from a 3.3 V supply?
No, the VOW2611-X017T is specified for VCC = 4.5 V to 5.5 V only. Its output logic thresholds (VEL ≤ 0.8 V, VEH ≥ 2 V) and VOL ≤ 0.6 V at 13 mA sink current are optimized for 5 V operation. Using 3.3 V risks violating the minimum VEH requirement and degrading noise margins; for 3.3 V systems, consider Vishay's VO615A or similar 3.3 V-compatible optocouplers instead of VOW2611-X017T.
How does the enable (VE) pin function in the VOW2611-X017T truth table?
The VE pin acts as a positive-logic strobe: when VE is high (≥2 V), the output VO reflects the LED state (low when LED on, high-Z when LED off); when VE is low (≤0.8 V), VO is forced high-Z regardless of LED state. This enables precise timing control-e.g., sampling only during valid data windows-without requiring additional logic gates or clock synchronization circuitry in the VOW2611-X017T design.
