AQY221R2S

Panasonic

AQY221R2S is a Panasonic PhotoMOS RF SOP 1 Form A solid-state relay in SOP-4, tube packing — R-type low-on-resistance variant, 40 V / 0.25 A load (0.75 A peak), AC/DC dual use, 0.8 Ω typical / 1.25 Ω maximum on-resistance, 13 pF typical output capacitance, 500 Vrms I/O isolation, 0.1 ms turn-on / 0.06 ms turn-off typical, rated −40 °C to +85 °C. The PhotoMOS construction is the selection point: an optically isolated MOSFET output with no moving contacts, so it switches small signals and loads for millions of operations where a mechanical reed relay wears out — test equipment, multiplexers and communication line switching. Selection advice: R2S is the R-type (low on-resistance); the AQY221N2S is the C-type (low capacitance: 0.12 A, 9.5 Ω typical, 1.0 pF, 1500 Vrms) in the same SOP-4 — same package, different electrical character, not interchangeable, so match the R vs N code to your load. Panasonic lists this model on its official product page; Future Electronics and RS Online list it as in stock and available for ordering. Evidence: the Panasonic official product page and datasheet ASCTB156E confirm the model number, 40 V/0.25 A rating, 0.8 Ω on-resistance and SOP-4 package.

SELECTION GUIDANCE

AQY221R2S selection guidance

AQY221R2S is a Solid-state relay (PhotoMOS) from Panasonic, orderable in the SOP-4 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

AQY221R2S FAQ

What do the suffixes in AQY221R2S mean?

Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. AQY221R2S names the SOP-4 configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for AQY221R2S?

The package (SOP-4) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.

Can you provide traceability documents for AQY221R2S?

Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.

How do I request a quotation for AQY221R2S?

Add AQY221R2S to your RFQ with the complete ordering code, the manufacturer (Panasonic), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
