Infineon Technologies PVT322S-TPBF

Overview

PVT322S-TPBF from International Rectifier is a Photo-voltaic relay / solid-state relay in the 8-SMD (0.300", 7.62mm) package. It uses an LED input and an optically isolated output structure so that a low-voltage control circuit can drive an isolated photovoltaic or MOSFET-output switching path.

For engineers reviewing the PVT322S-TPBF datasheet, PVT322S-TPBF pinout, PVT322S-TPBF application, or PVT322S-TPBF equivalent, this device is commonly used in isolated signal and load switching, photovoltaic gate drive, low-leakage solid-state relay outputs, and service and bom continuity designs. The package and suffix are important because PVI, PVN, PVA, PVT, PVG, and PVR devices often share family concepts but differ in output arrangement, relay rating, and mounting style. PVT322S-TPBF should therefore be selected by the exact technical documentation output rating rather than by package similarity alone.

Technical Context

In an isolated load-control design, PVT322S-TPBF transfers command energy across the optical barrier instead of sharing a direct electrical ground between the controller and the switched side. The input LED current, output leakage, on-resistance or photovoltaic output current, and isolation rating determine the actual usable load condition.

surface-mount gull-wing package for automated assembly while maintaining isolation spacing. The board layout should preserve isolation spacing between input and output pins, avoid leakage paths from flux residue or contamination, and keep the load side routing separate from the logic-side drive network.

For replacement work, the exact output type matters: photovoltaic-output optocouplers are used to drive external MOSFET gates, while PhotoMOS-style relay variants switch load current directly. The PVT322S-TPBF technical documentation should be used to confirm which function applies to this orderable line.

Key Specifications

Pinout & Package

The PVT322S-TPBF pinout must be reviewed from the exact package drawing because terminal function, thermal path, and mechanical footprint are linked in this product family. 8-SMD (0.300", 7.62mm) package information and Bulk packaging for this line.

For PCB design, use the package drawing and confirm copper area, soldering method, creepage or clearance where applicable, and the final orderable suffix before layout or replacement approval. surface-mount gull-wing package for automated assembly while maintaining isolation spacing.

Key Features

• Photo-voltaic relay / solid-state relay using LED input and optically isolated output behavior.

• 8-SMD (0.300", 7.62mm) package determines isolation spacing, board footprint, and soldering method.
• Suitable for low-leakage switching, isolated gate drive, or solid-state relay functions depending on exact family.
• No mechanical contacts, improving lifetime in low-current switching applications.
• Output rating and isolation voltage must be confirmed from the exact technical documentation before substitution.

Applications

Equivalent & Alternatives

When evaluating PVT322S-TPBF equivalent devices, engineers should compare only specific orderable alternatives and should verify package footprint, pinout, electrical ratings, thermal data, qualification status, and suffix or packing requirements before substitution.

Compared with related alternatives, PVT322S-TPBF should remain the preferred sourcing reference when the existing BOM, PCB footprint, and qualification documentation require the exact International Rectifier orderable device.

Quality

PVT322S-TPBF should be sourced as original International Rectifier / Infineon inventory through traceable and controlled supply channels. Quality verification may include package inspection, top-mark validation, label and lot review, solderability inspection, moisture-sensitivity handling review, and electrical screening according to the target production requirement.

Because PVT322S-TPBF is used in isolated switching and photovoltaic relay circuits, final validation should include the actual PCB footprint, thermal path, electrical stress, operating temperature, and fault-condition behavior. Traceable sourcing helps reduce counterfeit risk and supports repeatable performance in production, repair, and maintenance programs.

Availability

PVT322S-TPBF available at Aetrix Electronics and suitable for isolated switching and photovoltaic relay circuits requiring stable component supply, package matching, and controlled replacement planning.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and long-term availability support for OEM manufacturers, repair programs, and electronics production teams.

For production or repair deployment, confirming package type, orderable suffix, lifecycle status, environmental requirement, electrical rating, thermal condition, and sourcing continuity helps reduce procurement risk and improve manufacturing stability.

Manufacturer

International Rectifier was a semiconductor manufacturer known for power MOSFETs, IGBTs, gate drivers, power-management ICs, intelligent power switches, photovoltaic relays, and power modules. International Rectifier products became part of Infineon Technologies' power semiconductor portfolio after the acquisition of International Rectifier.

The PVT322S-TPBF ordering line should be reviewed with the relevant International Rectifier legacy technical documentation and Infineon supply-chain references where available. This is especially important for legacy MOSFETs, IRAM modules, PV relay products, and automotive AUIR power devices.

FAQ

What is PVT322S-TPBF used for?

PVT322S-TPBF is used in isolated switching and photovoltaic relay circuits. The exact application depends on the technical documentation electrical ratings, package, pinout, and thermal capability.

Where can I find the PVT322S-TPBF technical documentation?

The PVT322S-TPBF technical documentation should be obtained from International Rectifier / Infineon documentation or an authorized technical documentation source. It should be used to confirm ratings, package information, pinout, thermal data, and test conditions.

What should be considered in PVT322S-TPBF pinout design?

Pinout design should confirm the package drawing, terminal functions, thermal path, high-current routing or isolation spacing, and whether the orderable suffix changes package or packing details.

Can PVT322S-TPBF be used as a direct replacement?

PVT322S-TPBF can be used as a direct replacement only when the package footprint, pinout, electrical ratings, thermal behavior, and qualification status match the original design.

What are common PVT322S-TPBF equivalent solutions?

Equivalent solutions should be limited to specific orderable devices with verified technical documents. Suffix variants may differ in package, reel orientation, lead finish, qualification, or manufacturing status.
