Active production — sourcing posture for the BOM line
The DS28E50Q+T is listed as Active by Analog Devices, meaning the manufacturer continues to support new orders through their authorized channel.
What the 6-TDFN package means for your board
The 3x3 mm footprint is compact enough for space-constrained medical or portable designs, but the pad's thermal vias need to be accounted for in the layout to avoid solder voids. Surface-mount assembly with the 6-TDFN package is standard reflow-compatible. The exposed pad's solder paste coverage should follow the manufacturer's recommended stencil aperture to balance thermal transfer and voiding risk.
Authentication chip in a medical application context
Classified as an Authentication Chip under the DeepCover® series, the DS28E50Q+T provides cryptographic key storage and secure authentication for systems that must resist physical tampering. The Medical application designation means the device is suited for equipment requiring secure identity verification — infusion pumps, patient monitors, or diagnostic tools where counterfeiting of accessories or consumables must be prevented. The ROHS3 compliance covers the full substance restriction list including the four phthalates, which is often a prerequisite for medical device BOMs under EU MDR or similar regulatory frameworks.
