The BUB323Z is a planar, monolithic, high-voltage power Darlington with a built-in active zener clamping circuit. This device is specifically designed for unclamped, inductive applications such as Electronic Ignition, Switching Regulators and Motor Control.
The BUB323Z is a monolithic, high‑voltage power Darlington transistor designed for unclamped inductive applications such as electronic ignition, switching regulators and motor control. It features an integrated active‑clamp circuit and a tight clamping voltage window of 350 V to 450 V.
The device is supplied in a D2PAK (418B) package, supports up to 10 A continuous collector current, 150 W power dissipation, and operates from –40 °C to +125 °C. Thermal resistance is 1.0 °C/W (junction‑to‑case) and 62.5 °C/W (junction‑to‑ambient). Pb‑free versions are available.
