Product details
Overview
VOR1142B6T from Vishay Semiconductors is a solid-state relay (SSR) with SPST normally open configuration, GaAlAs IRED input and MOSFET output stage, delivering 5300 VRMS isolation, 400 V load voltage rating, and 22 Ω typical on-resistance in AC/DC mode - used to replace electromechanical relays in telecom switching and industrial control systems.
For engineers reviewing the VOR1142B6T datasheet, VOR1142B6T pinout, VOR1142B6T application, or VOR1142B6T equivalent, this device offers verified safety certifications (UL 1577, cUL, VDE 0884-5), bounce-free switching, and dual-load-current capability (140 mA AC/DC or 270 mA DC-only) critical for high-reliability metering and battery management designs.
Technical Context
The VOR1142B6T integrates an infrared LED driver and back-to-back MOSFET output stage in a single SMD-6 package, enabling galvanically isolated AC/DC or DC-only load switching without mechanical contacts. Its transfer characteristics are defined by IRED forward current thresholds (0.27–2 mA turn-on, 0.05–0.15 mA turn-off) and MOSFET gate drive coupling via optical isolation.
It supports two distinct output configurations: AC/DC mode (140 mA continuous, 22 Ω RON) and DC-only mode (270 mA continuous, 5.2 Ω RON), with corresponding off-state leakage <1 nA at ±100 V and 6 nA at ±400 V. Timing is characterized by 0.13 ms typical turn-on and 0.05 ms typical turn-off at 5 mA input drive.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VOR1142A6 | DIP-6 through-hole package; identical electrical specs and safety ratings. | Preferred for prototyping, manual assembly, or legacy board designs requiring axial leads. | Select VOR1142A6 when hand-soldering or wave-soldering is used; same timing and isolation performance as VOR1142B6T. |
| VO1263AD | Lower 4000 VRMS isolation; 120 mA load current; TO-220 package; no DC-only mode. | Suitable for lower-risk consumer-grade controls but not certified for industrial metering or telecom safety zones. | Choose VO1263AD only for cost-sensitive, non-safety-critical DC loads where 5300 VRMS and dual-mode operation are unnecessary. |
Compared with VOR1142A6, VOR1142B6T offers SMD manufacturability and higher thermal efficiency; versus VO1263AD, it delivers superior isolation, higher load current, and flexible AC/DC or DC-only configuration - making it the only option qualified for UL/VDE-certified industrial metering and telecom infrastructure.

FAQ
What is the maximum continuous load current for VOR1142B6T in AC/DC configuration?
The VOR1142B6T supports 140 mA continuous load current in AC/DC configuration, verified per its absolute maximum ratings and electrical characteristics table. This rating applies at Tamb ≤ +100 °C with proper PCB copper area for thermal dissipation. Exceeding this current risks exceeding the 550 mW output power dissipation limit and may trigger thermal shutdown or degradation. The VOR1142B6T datasheet specifies this value under "Continuous load current (AC/DC configuration)" with symbol IL = 140 mA.
Does VOR1142B6T support DC-only load switching, and what are its benefits?
Yes, VOR1142B6T supports DC-only load switching using pins 1, 2, 3, and 6 - bypassing pin 4. In this mode, it delivers 270 mA continuous current and 5.2 Ω typical on-resistance, reducing conduction losses by over 75% compared to AC/DC mode. This configuration is ideal for high-efficiency battery disconnect circuits in BMS, where minimizing voltage drop and standby leakage (<1 nA at ±100 V) directly extends operational lifetime. The VOR1142B6T datasheet confirms this in the "Electrical Characteristics" table under "On-resistance (DC only configuration)".
What safety certifications does VOR1142B6T hold, and how do they impact system design?
VOR1142B6T is certified to UL 1577 (5300 VRMS), cUL, and DIN EN 60747-5-5 (VDE 0884-5), including 8000 Vpeak transient isolation voltage and ≥8 mm creepage/clearance in SMD-6. These certifications allow designers to eliminate external isolation barriers in end-equipment safety schematics, reduce system-level certification effort, and meet IEC 61000-4-5 surge immunity requirements without additional protection circuitry. The VOR1142B6T safety ratings are explicitly validated in the "Safety and Insulation Ratings" section of its official Vishay datasheet (Doc #84300).
Can VOR1142B6T be driven directly from a 3.3 V microcontroller GPIO?
Yes, VOR1142B6T can be driven directly from a 3.3 V microcontroller GPIO using a series resistor. With a typical IRED forward voltage of 1.4 V at 10 mA and turn-on threshold as low as 0.27 mA, a 220 Ω resistor limits current to ~9.5 mA - well within the 50 mA absolute maximum and sufficient for reliable switching. The VOR1142B6T datasheet confirms VF = 1.4 V (typ) at IF = 10 mA and IFon = 0.27 mA (typ), ensuring compatibility with standard CMOS outputs without level-shifting or buffer stages.
How does the pin 5 "No Connect" designation affect PCB layout for VOR1142B6T?
Pin 5 on VOR1142B6T is internally unconnected and must remain electrically floating - it must not be tied to ground, VCC, or any other net. PCB layout must avoid solder mask openings, vias, or copper pours beneath pin 5 to prevent unintended coupling or contamination-related leakage paths. This requirement is specified in the "Pin Configuration" diagram and "Notes" section of the VOR1142B6T datasheet (Rev. 1.3), and violating it may compromise the 5300 VRMS isolation rating or increase off-state leakage beyond the guaranteed <1 nA.
