Low profile Schottky diodes increase power density

There are 26 new Schottky diodes in low profile, SMA and SMB flat packages that have been introduced by STMicroelectronics. They cover 25 to 200V and current ratings from 1.0 to 5.0A.

The 1.0mm high devices have 50 per cent lower profile than diodes in standard SMA and SMB packages, STMicroelectronics says, enabling designers to increase power density and save space. SMA and SMB footprint compatibility allows easy drop-in replacement. The Schottky diodes have higher current ratings than standard alternatives of the same footprint, so existing circuits that contain SMC diodes can be migrated to ST’s smaller SMB Flat devices, and from SMB to SMA Flat devices.

The Schottky diodes have inherently low forward voltage, for energy efficiency in industrial and consumer applications such as power supplies and auxiliary supplies, chargers, digital signage, game consoles, set-top boxes, e-bikes, computer peripherals, servers, telecomms cards, and 5G repeaters.

The Schottky diodes choices range from the 30V/1A STPS130AFN and STPS1L30AFN in SMA Flat to the 200V/4A STPS4S200UFN and 100V/5A STPS5H100UFN in SMB Flat. All devices have specified avalanche characteristics and feature a notched lead suitable for wave soldering and reflow.
