Reported by ODK Electronics on 2026-10-12. Summarized and analyzed by XAIPART Editorial.

What happened

China's new national energy-efficiency standard for EV chargers takes effect on 2026-11-01, and the source reports that this is accelerating the shift from silicon to SiC and IGBT devices in charging infrastructure.S1 With 800V vehicle platforms pulling demand in the same direction, the source expects further pressure on supply that is already tight.S1

On pricing, several integrated device manufacturers have announced price adjustments of 10-25% on power discretes since mid-year.S1 The source did not disclose which IDMs announced the adjustments or the affected part list.

The report also describes how procurement teams are responding: second-sourcing at design stage while the primary part is still available, pin-compatible MCU substitutions where software allows, longer-term wafer reservations for 2027 capacity, and keeping gate-driver and rectifier BOM lines flexible.S1

On the supporting parts around the main switch, the source names the STGAP2SICS SiC gate driver, the SIC1182K integrated SiC switch, the SIDC11D60SIC3 SiC diode, and the SURA8120T3G automotive rectifier as the devices that decide whether a power stage ships on time.S1

Background timeline

  1. - Several IDMs began announcing 10-25% price adjustments on power discretes from this point, per the source; the exact announcement dates are not disclosed. S1
  2. - China's national energy-efficiency standard for EV chargers takes effect. S1

XAIPART take

Technical impact

The charger standard effectively forces higher conversion efficiency, which in practice means SiC MOSFETs or advanced IGBT stages in new charger designs. Designers should re-verify gate-driver sizing and rectifier ratings when moving from silicon to SiC, because the STGAP2SICS-class gate driver and SIDC11D60SIC3-class diode are as schedule-critical as the main switch. Pin-compatible MCU substitution within AURIX, S32K3 or RH850 families can absorb single-source gaps without a platform redesign, provided the software stack tolerates the swap.

Market impact

With 10-25% price adjustments already announced on power discretes and 800V platform demand stacking on top of the charger standard, buyers relying on quarterly repricing face compounding cost. The source reports that buyers with 2027 visibility are locking wafer capacity now; XAIPART analysis suggests gate-driver and rectifier lines will tighten a quarter or two after main switches do, so supporting-cast lead times deserve the same tracking as SiC modules.

Action

Audit every power-stage BOM line before 2026-11-01: identify single-source main switches, gate drivers and rectifiers, and qualify pin-compatible alternates while primaries are still available. For 2027 production, request wafer-reservation quotes now rather than accepting quarterly repricing. XAIPART can support cross-referencing of SiC driver, diode and rectifier alternates from multiple qualified suppliers.

XAIPART Forecast

XAIPART expects that by Q1 2027, lead times on supporting SiC power-stage devices such as the STGAP2SICS gate driver and SIDC11D60SIC3 diode will extend beyond 20 weeks at major distributors if announced 10-25% price adjustments and the 2026-11-01 standard both hold; if those lead times stay under 12 weeks through 2027-03-31, this forecast is wrong. XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The source is a single distributor blog: it names no IDMs, no affected part lists, no reservation volumes, and gives no exact announcement dates, so these details remain unconfirmed.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
