Low profile Schottky diodes target industrial and consumer designs

July 29, 2020 //By Nick Flaherty
STMicroelectronics has launched 26 new Schottky diodes in low-profile SMA and SMB Flat packages, covering voltage ratings from 25 to 200V and current ratings from 1 to 5A.
STMicroelectronics has launched 26 new Schottky diodes in low-profile SMA and SMB Flat packages, covering voltage ratings from 25 to 200V and current ratings from 1 to 5A.

The 1.0mm-high Schottky diodes have 50 percent lower profile than standard SMA and SMB packages, enabling designers to increase power density and save space. SMA and SMB footprint compatibility allows easy drop-in replacement. In addition, the Schottky diodes have higher current ratings than standard alternatives of the same footprint, allowing migration of existing circuits that contain SMC diodes to ST’s smaller SMB Flat devices, and similarly from SMB to SMA Flat.

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

With long-term availability through ST’s 10-year Product Longevity Commitment, the Schottky diodes offer designers choices 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.

The typical price for the low-profile Schottky diodes, depending on rating and package, is $0.07 for orders of 10,000 units.
