Product details
Overview
VOH1016AB-VT from Vishay Semiconductors is a single-channel high-speed optocoupler with Schmitt-trigger output, 1 MBd data rate, 10 kV/μs common-mode transient immunity (CMTI), and open-collector logic-compatible output. It provides galvanic isolation for digital signal transmission between 3 V and 15 V domains in industrial control and microprocessor interfaces.
For engineers reviewing the VOH1016AB-VT datasheet, VOH1016AB-VT pinout, VOH1016AB-VT application, or VOH1016AB-VT equivalent, key selection criteria include guaranteed hysteresis ratio (0.5–0.9), low turn-on threshold (1–1.6 mA), propagation delay ≤0.5 μs, and SMD-6 180° orientation packaging for PCB layout compatibility.
Technical Context
The VOH1016AB-VT integrates a high-efficiency GaAs LED input stage with a monolithic photodiode + amplifier + Schmitt-trigger IC detector. Its open-collector output supports pull-up to any voltage within 3–15 V, enabling level shifting across isolated domains.
It delivers latch-up-free operation with guaranteed CMTI ≥10 kV/μs under both high- and low-input conditions (|CMH| and |CML|), and features hysteresis-based noise immunity via IF(on)/IF(off) ratio specification (min 0.5, typ 0.75).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | 2 MHz NRZ - supports high-speed serial communication without oversampling |
| Propagation delay (tPLH/tPHL) | 0.18 / 0.12 μs typ - enables sub-microsecond timing-critical isolation |
| CMTI | ≥10 kV/μs - ensures reliable operation in noisy motor drives and power supplies |
| Supply range | 3 V to 15 V - allows direct interface with 3.3 V, 5 V, and 12 V logic domains |
| Turn-on threshold | 1–1.6 mA at VCC = 5 V - reduces drive circuit power and simplifies MCU GPIO sourcing |
| Hysteresis ratio | 0.5–0.9 - prevents chatter on slow-rising or noisy input edges |
| Isolation voltage | 5000 VRMS (UL1577) - meets reinforced insulation requirements for industrial safety |
Pinout & Package
SMD-6 package, 180° orientation (lead frame rotated 180° vs standard SMD-6), 10.16 mm × 7.62 mm footprint, 0.4 mm minimum insulation thickness, >7 mm creepage/clearance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 (Cathode) | LED cathode | Reference for input current path; reverse voltage rating 6 V |
| 3 (NC) | No connect | Internally unconnected; must remain floating per datasheet |
| 4 (GND) | Output ground | Reference for detector IC; separate from input side - enables true galvanic isolation |
| 5 (VCC) | Output supply | Power for detector IC; supports 3–15 V; draws ≤1.3 mA in both high/low states |
| 6 (VO) | Open-collector output | Active-low Schmitt-trigger output; sinks up to 16 mA at VOL ≤0.4 V; requires external pull-up |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed optocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VOH1016AD | DIP-6 through-hole package; identical electrical specs and CMTI; no 180° orientation option | Preferred for prototyping or legacy through-hole PCBs; lacks SMD-6 footprint compatibility | Select when manual assembly or socket-based testing is required; not drop-in compatible with VOH1016AB-VT layouts |
| ACPL-K37T | 2.5 MBd data rate; higher CMTI (25 kV/μs); 5 V only VCC; different pinout (SO-5) | Better suited for ultra-noisy environments (e.g., inverters); incompatible pin assignment and package | Choose for enhanced noise immunity where board redesign is acceptable; not pin- or footprint-compatible |
Compared with VOH1016AD and ACPL-K37T, the VOH1016AB-VT uniquely combines SMD-6 180° orientation, 3–15 V VCC flexibility, and guaranteed 10 kV/μs CMTI in a cost-optimized industrial-grade package-making it optimal for space-constrained, multi-voltage embedded systems requiring production-ready surface-mount integration.

FAQ
What is the maximum data rate supported by VOH1016AB-VT?
The VOH1016AB-VT supports a maximum data rate of 2 MHz in NRZ format, verified under standard test conditions (RL = 280 Ω, VCC = 5 V). This exceeds its rated 1 MBd capability and enables reliable high-speed digital isolation in serial interfaces and real-time control loops. The VOH1016AB-VT achieves this with typical propagation delays of 0.12 μs (tPHL) and 0.18 μs (tPLH), making it suitable for timing-critical applications.
Does VOH1016AB-VT require an external pull-up resistor on the output?
Yes, VOH1016AB-VT has an open-collector output (pin 6, VO) and requires an external pull-up resistor to VCC or another logic rail. The value depends on speed and load: 280 Ω is used in datasheet timing tests, but values up to 10 kΩ are viable for lower-speed applications. The VOH1016AB-VT sinks up to 16 mA while maintaining VOL ≤0.4 V at VCC = 5 V, ensuring robust logic-level compatibility.
What safety certifications does VOH1016AB-VT hold?
VOH1016AB-VT is UL 1577 and cUL 1577 certified (5000 VRMS isolation), and qualifies for DIN EN 60747-5-5 (VDE 0884-5) with option "V" - though the "-VT" suffix indicates tape-and-reel packaging with VDE marking. It provides reinforced insulation with 6000 Vpeak transient voltage rating, 630 Vpeak repetitive peak voltage, and >7 mm creepage/clearance, meeting industrial safety standards.
Can VOH1016AB-VT operate with a 3.3 V supply on the output side?
Yes, VOH1016AB-VT supports VCC from 3 V to 15 V, including 3.3 V operation. At VCC = 3.3 V, the device maintains guaranteed performance: IF(on) remains ≤1.6 mA, VOL stays ≤0.4 V at IOL = 16 mA, and CMTI remains ≥10 kV/μs. This makes VOH1016AB-VT ideal for interfacing 3.3 V MCUs with higher-voltage systems without level shifters.
What is the meaning of the "-VT" suffix in VOH1016AB-VT?
The "-VT" suffix in VOH1016AB-VT denotes two specific manufacturing options: "V" indicates VDE 0884-5 certification (DIN EN 60747-5-5), and "T" indicates tape-and-reel packaging (1000 pieces per reel). The "-VT" variant is SMD-6 in 180° orientation, with VDE logo marked on the package per datasheet Fig. 17. The VOH1016AB-VT is fully compliant with both safety and packaging specifications indicated by this suffix.
