VO14642AABTR Visão geral
A solid-state relay (SSR) is an electronic switching device that uses semiconductor output elements (typically MOSFETs, IGBTs, or thyristors) instead of mechanical contacts to switch load circuits. SSRs belong to the broader hierarchy: optoisolator -> solid-state relay -> electromechanical relay -> switching component. The VO14642AABTR integrates an optical isolation barrier rated at 5300 VRMS, providing galvanic isolation between the low-voltage control logic and the high-voltage load. Compared with electromechanical relays, SSRs offer silent operation, no contact bounce, faster switching, and immunity to mechanical wear, at the cost of higher on-resistance and the need for thermal management.
Key features include a low-input forward current enabled by an efficient infrared LED, TTL/CMOS-compatible input logic, pure tin lead-free plating, and tape-and-reel packaging for high-volume SMD assembly. The DIP-6 footprint (also described as SMD-6 or 6-pin PDIP SMD) is a familiar, easy-to-place form factor that simplifies PCB layout. The VO14642AABTR supports operating temperatures up to +85 C and is RoHS compliant. A high input-to-output isolation voltage of 5300 VRMS makes it suitable for safety-critical systems requiring reinforced isolation.
Typical applications include industrial automation I/O modules, programmable logic controller (PLC) output cards, battery management systems, solenoid and actuator drivers, medical equipment signal switching, and instrumentation multiplexing. The bounce-free switching characteristic is particularly valuable in measurement systems that are sensitive to mechanical contact transients.
When designing with the VO14642AABTR, pay attention to the thermal path: even with a low RON of 0.25 ohm, a 2 A load dissipates approximately 1 W in the output MOSFET. Provide adequate copper area on the PCB to keep the junction temperature within safe limits. A reverse-polarity protection diode across the load is recommended for inductive loads such as solenoids or relays.

Aplicações típicas
VO14642AABTR é adequado para 6 aplicaçãos: Industrial Automation I/O Modules, Battery Management System (BMS) Switching, PLC Digital Output Cards, Medical Equipment Signal Switching, Solenoid and Valve Driver Switching, Test and Measurement Multiplexing.
Industrial Automation I/O Modules
The VO14642AABTR fits 24V industrial automation I/O modules because its 60V/2A load envelope covers both 24V DC and 48V DC industrial rails with significant margin. Its 800 microsecond turn-on/turn-off time and bounce-free MOSFET switching eliminate the contact wear and EMI spikes that plague electromechanical relays in PLC output cards, extending field MTBF in continuous-duty assembly lines. The 5300 VRMS isolation satisfies IEC 61131-2 reinforced isolation requirements between field wiring and logic. PCB thermal management must dissipate roughly 1 W at full 2 A load, easily handled by 1 square inch of 2 oz copper.
Recomendado
Battery Management System (BMS) Switching
The VO14642AABTR is well suited to battery management switching roles such as pack balancing, pre-charge, and isolation contactor bypass because its MOSFET-based output passes DC cleanly without the polarity restrictions of triacs or phototriacs. The 60V load rating covers 12V, 24V, and 48V battery packs with safety margin, and the 2 A current envelope handles pre-charge resistor bypass paths and active balancing currents. Bounce-free switching prevents the inrush transients that can confuse coulomb-counting fuel-gauge ICs. Add a TVS across the output to clamp inductive transients from motor loads.
Recomendado
PLC Digital Output Cards
The VO14642AABTR integrates well into PLC digital output cards targeting 2 A per-channel switching at 24 V DC or 48 V AC. Its TTL/CMOS-compatible LED input allows direct drive from 3.3 V or 5 V logic without additional driver circuitry, simplifying the output-card BOM. Compared to electromechanical relays, the SSR eliminates audible click noise and contact bounce, both of which are problematic in laboratory and medical environments where PLCs are deployed. Per-channel power dissipation of approximately 1 W at 2 A mandates either output current derating to 1.5 A or substantial PCB copper pour.
Recomendado
Medical Equipment Signal Switching
In medical signal switching paths such as patient monitor channel multiplexing and infusion pump solenoid drivers, the VO14642AABTR provides the 5300 VRMS reinforced isolation required by IEC 60601-1 between patient-connected leads and the low-voltage control domain. The solid-state output eliminates the arcing and mechanical wear that would otherwise pose long-term reliability concerns in life-support equipment. The low input drive current (typically 5 mA LED) keeps the optocoupler drive circuit simple. Use a slow-blow fuse on the load side for patient-protection fault clearing.
Recomendado
Solenoid and Valve Driver Switching
The VO14642AABTR suits solenoid and valve driver interfaces in process automation and HVAC systems because its low 0.25 ohm RON keeps the driver stage efficiency high when energizing 24 V DC solenoid coils at currents up to 2 A. Bounce-free MOSFET switching eliminates the coil-driver arcing that wears mechanical relay contacts over millions of cycles. Always add a flyback diode across the solenoid coil and a TVS across the SSR output to absorb the inductive kickback, which can otherwise exceed the 60 V load voltage rating.
Recomendado
Test and Measurement Multiplexing
For automated test equipment (ATE) and instrumentation multiplexing, the VO14642AABTR delivers clean bounce-free switching that does not inject mechanical-transient noise into precision measurement channels. Its 800 microsecond turn-off time is acceptable for scan-multiplexed voltmeters and data-acquisition switching but is too slow for high-speed RF multiplexing. The 0.2 ohm typical RON contributes negligible series resistance for low-current signal paths; for high-current loads, compensate for voltage drop in calibration routines. The 5300 VRMS isolation protects sensitive front-end amplifiers from chassis-ground transients.

Notas de projeto
Estimated: at the full 2 A continuous load, the VO14642AABTR dissipates approximately I^2 * R = 4 * 0.25 = 1.0 W in the output MOSFET. With a typical SMD-6 theta_JA near 80 C/W (estimated), the junction-to-ambient rise is around 80 C, requiring either derating to roughly 1.5 A continuous at 25 C ambient or provision of at least 0.5 square inch of 2 oz copper pour on the drain/source pads. Forced-air cooling further extends the safe operating current.
Route the high-current load traces on the top layer to the drain/source pads (pins 4-6) using wide traces (at least 50 mil per 1 A) to minimise resistance and heating. Keep the input traces (pins 1-2 LED) narrow and away from the output traces to maintain the 5300 VRMS isolation; maintain at least 8 mil creepage across the package body. Place a 0.1 microfarad bypass capacitor near the LED input if the drive signal comes from a long cable or noisy environment.
Do not exceed the 60 V load voltage rating - inductive kickback from solenoids or transformers can destroy the output MOSFET. Always add a flyback diode (1N4007 or similar) reverse-biased across the coil, or a bidirectional TVS (such as P6KE62CA) across the output terminals for AC loads. Avoid driving the LED above 50 mA DC or below 5 mA (CTR becomes unreliable). The pins 4-5-6 output configuration differs between AC/DC and DC-only modes - consult the datasheet figure for the correct wiring for your load type.
