The DIP-29 is a high-pin-count dual in-line package that inherits all the classic advantages of the DIP family while offering expanded I/O capability for more complex system designs.
Despite featuring up to 29 leads, it retains the thick through-hole pins and rigid structure that characterize traditional DIP packages.
When soldered through the PCB, these leads provide extremely durable mechanical bonding, ensuring long-term electrical integrity under demanding operating conditions.

The larger molded body of the DIP-29 also serves as an effective passive heat spreader. Its flat top and bottom surfaces allow for easy installation of clip-on or integrated heatsinks, and even direct thermal coupling with the chassis, unlocking substantial thermal dissipation potential.
This combination of mechanical durability, thermal efficiency, and scalability makes the DIP-29 a preferred package for high-power or high-pin-count applications across industrial control, automotive electronics, and aerospace systems.
