STMicroelectronics has launched 26 new Schottky diodes in low-profile SMA and SMB Flat packages, covering voltage ratings from 25 to 200 V and current ratings from 1 to 5 A. The 1.0 mm-high devices have 50% lower profile than diodes in standard SMA and SMB packages, enabling designers to increase power density and save space. […]

Schottky diodes could say goodbye to parasitic resistance
Examine the typical equivalent circuit schematic for a Schottky diode and you’ll find one of the elements is a series resistance. That resistance represents the behavior of the interface between the diode semiconductor material and the metal contact. It turns out that the termination of the semiconductor crystal against a metal creates metal-induced gap states […]
Less famous attributes of Schottky diodes
Schottky diodes are useful in some power-converter topologies, especially for shunting the body diode in a half-bridge’s low-side MOSFET. In this position, the Schottky diode prevents the body diode from turning on, particularly when driving inductive loads common in power converters, because it’s forward voltage drop is smaller than that of the body diode’s PN […]
