Leshan Radio Company (LRC)

Leshan Radio Company (LRC), based in Leshan, Sichuan, is one of China's longest-established discrete semiconductor makers, re-implementing industry-standard discrete designations under its own datasheets, marking codes and electrical tables. The profiles here cover three of those discretes: the LESD8D5.0CAT5G ESD protection diode, the LMBTA56LT1G PNP bipolar transistor in SOT-23, and the L2N7002LT1G 60 V small-signal N-channel MOSFET — LRC's build of the ubiquitous 2N7002, marked 702. The leading S- on a sibling code (S-L2N7002LT1G) marks a different, automotive-oriented variant that is not interchangeable with the plain code, so the full string on the offered lot is what an RFQ should quote; qualify a design against LRC's own table for the exact code rather than figures borrowed from another maker's version.

Sourcing notes for Leshan Radio Company (LRC) 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.
