PVG612SPBF Übersicht
What is a photovoltaic relay? A photovoltaic relay (also called a photorelay or solid-state relay, SSR) is an optoisolated switch that uses light from an input LED to drive an embedded photovoltaic cell, which in turn biases the gate of a MOSFET output. In the system hierarchy it sits between an optocoupler (signal-level isolation) and a power MOSFET relay (high-current switching) - combining galvanic isolation with silent, bounce-free, semiconductor switching. Compared with electromechanical relays (EMRs), PVRs offer unlimited mechanical life, no contact bounce, magnetic-field immunity, and sub-millisecond switching.
Key features include a 60 V maximum load voltage (AC or DC), 1 A continuous AC / 2 A DC load current, 0.5 ohm maximum on-resistance (RDS(on)), 25 mA typical forward LED current (If), and 4 kV input-to-output isolation voltage. The PVG612SPBF is part of the Pb-free (PBF) variant, supplied in tape-and-reel packaging suitable for high-volume automated assembly. Its compact 6-SMD footprint replaces larger EMR packages, simplifying PCB layout and reducing component count in dense designs.
Architecturally, the PVG612SPBF uses a GaAlAs infrared LED on the primary side, optically coupled to a series-stacked photovoltaic (PV) cell array that generates the gate-drive voltage for the HEXFET output MOSFET. This two-stage approach - LED to PV cell to MOSFET gate - provides true galvanic isolation while maintaining a clean, isolated MOSFET switching characteristic with very low leakage and stable on-resistance.
Typical applications include isolated low-current power switching in telecom line cards, battery management systems, industrial PLC I/O modules, programmable logic controller (PLC) outputs, and instrumentation multiplexer switching. Designers favor the PVG612SPBF for switching 12 V to 48 V AC or DC loads where silent operation and long life are required.
When designing with this part, observe the 25 mA nominal LED forward current (If) and add a current-limiting resistor to limit If to safe levels. The MOSFET output requires a minimum load to maintain the off-state leakage specification - leave at least 1 to 2 mA flowing through the output to keep the part in the linear region. Always verify thermal dissipation under DC loads.

Typische Anwendungen
PVG612SPBF ist geeignet für 6 Anwendungs: Telecom Line Card Switching, Industrial PLC Digital Output Module, Battery Management Isolation Switching, Instrumentation Multiplexer Switching, Medical Equipment Patient Isolation, Security and Surveillance System Switching.
Telecom Line Card Switching
The PVG612SPBF suits telecom line-card applications where 60 V load voltage and 1 A continuous current cover typical -48 V battery feed switching and ringing signal routing. Its 4 kV isolation meets ITU-T K.20/K.21 surge requirements when paired with external TVS protection, and its HEXFET output delivers sub-1 millisecond turn-on - critical for low-latency packet-routing switchovers. The 0.5 ohm on-resistance keeps conduction loss under 0.5 W at full load, eliminating the need for a heatsink on dense line cards. Engineers commonly pair it with a series current-limiting resistor on the LED input driven by a 3.3 V or 5 V logic rail, making it ideal for centralized office switches.
Empfohlen
Industrial PLC Digital Output Module
In a PLC digital output module the PVG612SPBF switches 24 V DC loads at up to 2 A DC directly from the field side, eliminating mechanical relay wear in high-cycle applications like packaging lines and conveyor control. Its 6-SMD footprint is significantly smaller than a comparable EMR, enabling higher channel density on the same PCB. The 4 kV isolation safely separates the 24 V field wiring from the 3.3 V backplane logic, satisfying IEC 61131-2 requirements for industrial control. Designers add an RC snubber across the output to limit dv/dt on inductive loads (solenoids, valves) and an LED drive resistor on the logic-side input.
Empfohlen
Battery Management Isolation Switching
In a battery management system (BMS) the PVG612SPBF provides galvanically-isolated switching for low-current paths such as cell-balancing resistor activation, pre-charge circuits, and auxiliary load disconnect. The 4 kV isolation barrier lets the low-voltage BMS MCU control high-voltage battery nodes safely, while the 0.5 ohm RDS(on) keeps conduction loss minimal during cell balancing. Its solid-state design operates reliably across -40C to +85C automotive temperature grades, making it suitable for under-the-hood and pack-mounted BMS electronics. The 60 V load rating also covers 48 V mild-hybrid battery systems now common in modern vehicles.
Empfohlen
Instrumentation Multiplexer Switching
Test and measurement instruments use the PVG612SPBF as a low-leakage analog signal multiplexer switch on the input or output side of a precision ADC or DAC. Its HEXFET output exhibits very low leakage at room temperature, preserving measurement accuracy for high-impedance signal sources. The 60 V rating accommodates general-purpose bench-instrument ranges up to +/-30 V, while the 4 kV isolation protects sensitive downstream circuitry from fault events on the input. With sub-millisecond switching the PVG612SPBF also enables fast scan rates in automated test equipment (ATE) pin-electronics cards.
Empfohlen
Medical Equipment Patient Isolation
Medical devices with patient-applied circuits - infusion pumps, patient monitors, ECG front ends - use the PVG612SPBF to maintain a 4 kV isolation barrier between mains-referenced control electronics and the isolated patient side. The photovoltaic drive mechanism draws no continuous current from the isolated side, preserving battery life in portable devices. Its solid-state reliability eliminates the click and bounce of EMRs, providing quieter operation in bedside equipment. The 60 V load voltage handles typical 12 V and 24 V medical-rail voltages with comfortable margin for fault conditions.
Empfohlen
Security and Surveillance System Switching
In security systems the PVG612SPBF switches 12 V DC or 24 V AC loads for sirens, strobe lights, magnetic door locks, and motion-detector relay outputs. Its silent solid-state operation is preferred in indoor installations where EMR clicking would be objectionable. The 60 V / 2 A DC rating covers the inrush of magnetic locks and alarm horns without contact welding. The 4 kV isolation protects the central alarm-panel logic from transients injected by outdoor wiring - especially important for perimeter installations exposed to lightning-induced surges.

Designhinweise
Estimated: at 60 V load and 1 A DC continuous load, conduction loss is approximately P = I^2 * R = 1^2 * 0.5 = 0.5 W. The 6-SMD package dissipates this heat through the PCB copper pads; a copper area of at least 100 mm^2 on the drain/source pads is recommended to keep the junction rise below 30C. For 2 A DC operation conduction loss doubles to 2.0 W - use 200 mm^2 of copper or a forced-air cooling path. Always observe the SOA curve in the Infineon datasheet when switching inductive loads.
Keep the input LED traces (pins 1-2) physically separated from the output MOSFET traces (pins 3-6) by at least 2 mm of creepage on the PCB to maintain the 4 kV isolation rating. Place a current-limiting resistor for the input LED close to the IC pin (within 5 mm) and bypass any noise on the LED supply with a 100 nF ceramic capacitor. Use wide copper pours on the drain/source pins to spread heat and reduce voltage stress during switching.
The PVG612SPBF output MOSFET requires a minimum load current to maintain a stable off-state leakage specification - leaving the output fully floating (no load) can cause undefined leakage behavior on high-impedance circuits. Do not exceed 25 mA continuous forward current through the input LED without derating. Avoid switching highly inductive DC loads without an external flyback diode or TVS clamp, as the HEXFET output has no built-in freewheeling path and avalanche breakdown can damage the part.
