IrDA Transceiver Modules

IrDA Transceiver Modules

IrDA transceiver modules are the parts that handle short-range infrared data links between devices, converting electrical signals into infrared pulses and back again. If you have ever seen a device beam data to another device across a desk or a few meters of open space, there is a good chance one of these modules is doing the work. They are still used widely in metering, medical equipment, industrial handhelds, and legacy consumer electronics where a physical cable or radio link would add cost or complexity. Most buyers in this category are looking at modules built around the IrDA 1.x physical layer standard, with data rates typically ranging from 9.6 kbps up to 4 Mbps depending on the variant. You will see SIR (Serial Infrared) parts at the lower end and FIR (Fast Infrared) modules at the higher end. Package type matters a lot here. Some designs need a low-profile surface-mount module, others need a through-hole part with a built-in shield, and the wrong choice can mean a board spin or an awkward mechanical workaround. When sourcing these parts, engineers and buyers tend to ask the same few questions. Is the module still in active production, or is it a discontinued part being sourced from the grey market? Counterfeit risk is real with older IR modules, especially for parts that Vishay or Sharp phased out years ago. Lead time versus price is another common tension. A franchised channel might quote twelve weeks, while an independent distributor can often pull from spot stock in days, but you need to verify date codes and packaging condition before committing. Tape and reel versus bulk tray is worth confirming too, especially if your line is set up for automated placement. If you know the part number you need, or even just the general spec, the fastest way to get moving is to check current stock and request a quote directly at icxing.com.

Frequently Asked Questions

Are older IrDA modules from Vishay or Sharp still available, or are they all counterfeit now?

Many older IrDA parts are officially discontinued, but genuine surplus stock does exist through authorized and reputable independent channels. The key is verifying date codes, packaging condition, and traceability documentation before you buy. If a price looks too good for a long-obsolete part, treat that as a red flag rather than a bargain.

What data rate do I need, SIR or FIR?

SIR modules handle up to 115.2 kbps and are fine for simple serial links, remote controls, and basic metering. FIR modules go up to 4 Mbps and are used where faster data transfer is needed, like image transfer between devices or higher-speed industrial links. Check your host controller's IrDA encoder support first, because that usually decides the answer for you.

Does package type really matter that much for IrDA transceivers?

Yes, more than people expect. These modules come in a range of heights and mounting styles, and the optical window placement is fixed relative to the package body. If your enclosure or bezel was designed around a specific module height, swapping in a different package without checking the mechanical drawing can leave the optical path blocked or misaligned.
