We are not a catalog distributor. We source, validate, and deliver the components that keep your power systems running.
SiC and GaN spot pricing swings 20–30% quarter-to-quarter during EV ramp cycles. ADD locks quarterly fixed pricing on recurring power BOM lines — Infineon CoolSiC, STMicroelectronics STPOWER, TI gate drivers. HK buffer stock, weekly pull. Price certainty across your inverter production run, not subject to the spot market.
Power stage BOMs span SiC/GaN discretes, gate drivers, current sensors, magnetics, DC-link capacitors, and connectors across 10–15 brands. ADD consolidates Infineon + STMicroelectronics + TI + Wolfspeed + KEMET/TDK into one PO, one QC package, one DDP shipment. One relationship for your entire traction inverter, EV charger, or solar inverter build.
Power converter and inverter designs have 10–20 year field lifetimes. ADD monitors Infineon, STMicroelectronics, onsemi, and Wolfspeed power semiconductor EOL notices and alerts you 12–24 months ahead. We coordinate lifetime buys across the full power stage BOM before the last-time-buy window closes and your field service stock is at risk.
When Infineon or onsemi SiC MOSFETs hit 40+ week allocation, we cross-reference functionally equivalent alternates across STMicroelectronics, Wolfspeed, Rohm, Microchip. Our FAEs provide RDS(on), Qg, and thermal resistance comparison so your power design team can approve the alternate within 48 hours — same package, same gate drive voltage, no PCB change.
Infineon CoolSiC MOSFETs and IGBT modules, STMicroelectronics STPOWER SiC, onsemi EliteSiC, and TI isolated gate drivers are our highest-turn power electronics lines. HK/SG buffer stock across 1,800+ power semiconductor part numbers. When EV charger and inverter build cycles drain global SiC allocation, our buffer inventory keeps your power stage production running.
Power semiconductor supply chain: Infineon (IGBT modules, CoolSiC MOSFETs, CoolGaN, EiceDRIVER gate drivers), STMicroelectronics (STPOWER SiC MOSFETs, IGBTs, galvanic isolated gate drivers), onsemi (EliteSiC, IGBT, MOSFET), Wolfspeed (SiC MOSFETs, Schottky diodes), TI (isolated gate drivers, current sensing, digital power controllers). 1,200V–1,700V device range standard — multi-sourced across authorized and vetted independent channels.

Automotive-grade MCUs are on severe allocation. Tier-1 suppliers face production line stoppages waiting for 32-bit MCU deliveries.
Multi-source AEC-Q100 MCU alternatives, 2-week delivery
Sealed connectors and high-speed FAKRA/HSD interconnects face extended factory lead times, delaying harness production.
Global connector sourcing network, 10-day ship
Sourcing from unauthorized channels means missing Production Part Approval Process documentation - a non-starter for automotive quality systems.
Full PPAP Level 3 documentation with every order
When your only qualified MOSFET supplier goes on allocation, your entire power stage is at risk with no fallback.
Cross-reference AEC-Q101 alternates with matching footprints
AEC-Q100 qualified: STM32, SPC5, RH850 - 32-bit ARM Cortex-M/R for body, chassis, and gateway.
AEC-Q100 PMICs, DC-DC converters, gate drivers - power supply for ADAS, infotainment, and body.
AEC-Q101 MOSFETs, IGBTs, SiC, and diodes - from 40V body electronics to 1200V traction inverters.
Automotive-grade connectors, MLCCs, resistors - sealed, high-speed, and high-temperature rated.
An EV Tier-1 supplier building on-board chargers needed SiC MOSFETs, isolated gate drivers, current sensors, and AEC-Q200 MLCCs - fragmented across 12 different vendors with lead times from 4 to 26 weeks.
ADD consolidated the entire BOM, sourcing SiC discretes from multiple authorized channels and holding buffer stock at our Hong Kong warehouse. We delivered synchronized weekly batches against production schedules. 18% cost reduction through consolidated procurement. Zero line stoppages.
