Founded: 1966 · HQ: Plano, Texas, USA
Diodes Incorporated is a NASDAQ-listed (DIOD) semiconductor manufacturer founded in 1966 and headquartered in Plano, Texas — one of the longest-established discrete-semiconductor specialists in the industry, with design, fab and assembly operations across the US, Europe and Asia. Diodes Inc. supplies the full discrete catalog: small-signal and power transistors, rectifiers, bridges, MOSFETs, protection arrays and analog. Its highest-volume parts in the sourcing market include the S8050/S8550 complementary NPN/PNP transistor pair (40 V, 1.5 A, the workhorse switching transistors of Asian consumer electronics and hobby circuits), the FR107 fast-recovery rectifier (1000 V, 1 A, 500 ns trr — for high-frequency switching supplies where a 1N4007 is too slow), and the KBPC5010 single-phase bridge rectifier (1000 V, 50 A) used in chargers, welders and power supplies. Our Shenzhen warehouse stocks S8050, S8550, FR107 and KBPC5010 from Diodes Inc. authorized distribution, with forward-drop and surge-current verification on every lot to catch the remarked bridge and rectifier market.

Sourcing from Diodes Incorporated – FAQ
Is the KBPC5010 counterfeit-prone?
Yes — KBPC bridge rectifiers are among the most remarked discretes because the package is trivial to relabel and the fraud is profitable: a 10-25 A die resold as a 50 A KBPC5010. Fakes overheat, sag voltage and fail under surge — often destructively. We load-test samples from every lot: forward voltage at 10 A+ per leg, surge-current pulse testing, thermal imaging at sustained current, and die-level inspection on suspect stock. All KBPC5010 we ship is from Diodes Inc. authorized distribution with lot traceability.
What are the S8050 and S8550, and what do they replace?
The S8050 (NPN) and S8550 (PNP) are a complementary 40 V, 1.5 A small-power transistor pair in TO-92 and SOT-23 — the standard switching/amplifier transistors of Asian electronics design, commonly used for relay drive, LED strings, audio preamps and general switching where 2N3904/3906 (0.2 A) is too small. hFE comes in binned grades (typically marked L/H/D, covering ~60-400). They cross-reference with KSP/KSA and 2SC/2SA equivalents; specify the hFE bin on your RFQ if your design is gain-sensitive.
When should I use FR107 instead of 1N4007?
Both are 1000 V, 1 A rectifiers, but recovery time differs by nearly two orders of magnitude: the 1N4007 is a standard-recovery diode (µs-class trr) fine for 50/60 Hz mains rectification, while the FR107 recovers in ~500 ns, making it suitable for switch-mode supplies, flyback outputs, freewheeling and inverter circuits where a slow diode would cause shoot-through losses and EMI. Rule of thumb: anything switching above a few kHz needs the FR-series. Same DO-41 footprint — drop-in for most layouts.
Is Diodes Incorporated a legitimate company, and what is its lead time?
Diodes Inc. is a S&P MidCap 400 constituent listed on NASDAQ since 1992 (founded 1966), headquartered in Plano, Texas, with revenue above $1.3 billion and manufacturing across three continents — one of the world's largest discrete-semiconductor suppliers. Diodes authorized channel quotes 8-16 weeks for catalog discretes. Our Shenzhen warehouse holds S8050, S8550, FR107 and KBPC5010 for 1-2 day shipment, with original Diodes packaging and lot codes on every order.
