We are not a catalog distributor. We source, validate, and deliver the components that keep your missions on schedule.
Radiation-tolerant, hi-rel, and COTS+ semiconductor supply chain for defense and space-grade programs. Xilinx/AMD (Kintex UltraScale, RTAX, RT PolarFire), Microchip (RTG4, radiation-tolerant FPGAs), TI (space-grade power management, radiation-tolerant analog), Infineon/IR (RAD-Hard MOSFETs), STMicroelectronics (radiation-hardened power discretes). Full ITAR/EAR compliance on every shipment — source-disclosed with export classification.
Defense program budgets are locked years in advance — spot pricing on rad-hard components isn't workable. ADD locks quarterly fixed pricing on your recurring MIL-SPEC BOM lines — Xilinx FPGAs, Microchip RTG4, TI space-grade PMICs. HK ITAR-compliant buffer stock, per-schedule pull. Price certainty across your SRR, PDR, and CDR milestones.
Defense electronics BOMs span rad-hard FPGAs, hi-rel power discretes, precision timing, connectors, and space-grade passives across 12–20 manufacturers. ADD consolidates Xilinx + Microchip + TI + Infineon + Glenair into one PO, one export compliance package, one DDP shipment — one relationship for your classified and unclassified programs.
Defense and space programs span 10–30 year lifecycles — component EOL is a mission risk. ADD monitors Xilinx, Microchip, TI, and Infineon hi-rel product lifecycle and EOL notices and alerts your program office 18–36 months ahead. We coordinate lifetime buys across the full BOM tree — rad-hard FPGAs, hi-rel discretes, space-grade passives — before the LTB window closes.
When a single-source hi-rel MOSFET or rad-hard FPGA threatens program continuity, we cross-reference radiation-tolerant alternates across Infineon, STMicroelectronics, Microchip, Renesas. Our FAEs provide TID/LET radiation test data and form-fit comparison so your reliability engineering team can assess the alternate within 48 hours — no redesign cycle, no requalification delay.
Xilinx Kintex UltraScale FPGAs, Microchip RTG4, TI space-grade PMICs, and Infineon RAD-Hard MOSFETs are our core aerospace and defense lines. HK buffer stock with ITAR-registered warehousing. When MIL-SPEC parts hit 52-week lead times, our pre-qualified inventory keeps your program on schedule without waiting on factory allocation.

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.
