Housed in a TO-92-3 package (TO-226-3 with formed leads), it is a through-hole mounted device — the three-lead transistor outline is a standard footprint that hand-solders or wave-solders without special reflow profiling, though the lead pitch and body size mean it sits above the board, so pick-and-place requires a tape feeder or tube feed, not a tray. ## Active production and compliance status The Tape & Reel (TR) and Cut Tape (CT) packaging options mean the part ships on standard 13-inch reels for automated assembly or in cut-tape lengths for prototype and low-volume builds. No official successor or pin-compatible alternative is published by the manufacturer. ## Where the part fits in a BOM Classified under Microcontrollers & Processors (MCU / MPU / DSP), the DS28E25+T is a dedicated security coprocessor — it does not run user firmware but executes a fixed authentication protocol. The TO-92-3 footprint is shared with many temperature sensors and small-signal transistors, so the board layout is straightforward: the three leads are VDD, GND, and the 1-Wire data line. Target applications are Authentication and Security — typically consumable authentication (printer cartridges, medical disposables), accessory validation, or secure credential storage. The DeepCover® series embeds tamper-detection and cryptographic countermeasures against invasive attacks.","metaTitle":"DS28E25+T DeepCover Authentication Chip, TO-92-3","metaDescription":"Analog Devices DS28E25+T DeepCover authentication chip, TO-92-3 package, active production.
