COMMON CHALLENGES
Lead time is the only real bottleneck in power devices
- Lead times stretch from 20 to 40+ weeksWhen capacity tightens, factory schedules double and your ramp-up plan is at their mercy.
- Domestic alternatives feel unsafeThe price is lower — but who guarantees consistency at volume, switching losses and thermal behaviour?
- Discretes and modules drift apartSwitch, driver and module come from different suppliers; any single delay holds up the build.
- SiC validation cannot be rushedAutomotive and industrial qualification takes time, so the schedule must be locked early.
POPULAR PART NUMBERS
Commonly stocked and commonly sourced
| Sub-category | Common part number families | Sourcing note |
|---|---|---|
| MOSFET | IRF / IRFP series · IPD / IPB / IPP (Infineon) · FQP / FDP (onsemi) · CRSS series (CR Micro) | Select on Rds(on), Vds and package; compare switching losses for substitutes |
| IGBT | IKW / IKP (Infineon) · FGH / FGL (onsemi) · common 600V/1200V modules | Discretes and modules differ widely in lead time — dual-source both |
| SiC | C3M / C4M (Wolfspeed) · IMZ / IMW (Infineon CoolSiC) | Long validation — lock the schedule early |
| Gate drivers | IR2110 / IR2136 · UCC series (TI) | Buy alongside the switch to avoid schedule mismatch |
| Rectifier diodes | MUR / MBR series · 1N series rectifiers | Commodity parts — price-sensitive, good for consolidated bidding |
| Power modules | Common DC-DC and brick modules | Confirm power and thermal ratings before committing volume |

FAQ
Frequently asked questions
How do you validate a domestic alternative?
Free samples for bench testing plus a side-by-side table of key parameters such as Rds(on), Vth and switching losses. Once it passes, we switch in two steps: pilot lot, then volume.
Do you hold SiC in stock?
Common ratings (650V / 1200V) are regularly stocked. Special packages require a confirmed schedule, and we give you a committed date rather than a vague “TBD”.
How do you shorten a 40-week lead time?
Three parallel paths: expediting through original channels, sourcing the global spot market, and verified alternatives. We normally return an executable plan within 1–2 weeks.
