Semtech

Semtech is the company behind LoRa, and the profiles here show its two strengths: sub-GHz LoRa transceivers for long-range IoT links alongside TVS protection diodes for ESD-sensitive interfaces. The SX1262 and SX1268 cover the 868/915 MHz and 470 MHz bands respectively — confirm the regional frequency plan before specifying, since the two codes are not interchangeable across markets. The SRV05-4 is a quad TVS array for high-speed data lines. When sourcing Semtech LoRa parts, match the exact band variant to your deployment region and confirm the SPI interface timing against your host MCU.

Sourcing notes for Semtech parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
