Product details

The 2SD1818-AZ is an NPN silicon power transistor, a general-purpose switching and linear amplifier device for medium-power circuits. It is specified for applications such as power supply pass elements, motor drive pre-drivers, and relay coil drivers where a single bipolar transistor handles moderate current and voltage.

This is the preferred lifecycle stage for production BOMs that need supply continuity without obsolescence-driven redesign.

Frequently asked questions

What is the best replacement for 2SD1818-AZ?

No official cross-reference or second-source alternate is listed for the 2SD1818-AZ. For a pin-compatible substitute, compare the package outline and electrical ratings (Vceo, Ic, hFE) against a same-case NPN power transistor such as the 2SD882 or 2SD1802 — but confirm the specs match your operating point before substituting.
