This document describes the features and characteristics of the Schottky bridge rectifier and freewheel diode used in the MR16 LED driver solution.
The ZXSBMR16PT8 is a low‑leakage Schottky bridge and freewheel diode designed for MR16 LED driver circuits. It combines a bridge rectifier and a freewheel diode in a compact surface‑mount package, reducing component count.
Key specifications include a maximum repetitive reverse voltage of 40 V, average forward current of 0.4 A, peak forward current of 3.5 A, and a power dissipation of 1 W at 25 °C. The device operates over a storage temperature range of –55 °C to +150 °C and is supplied in an SM8 surface‑mount package.
