The RBS1LAM40ATR is a Schottky diode & rectifier manufactured by ROHM. It is a 20V, 1A device and is often used in power supplies and low power circuits. It is designed as a efficient, low-cost rectifier for use in applications such as voltage regulation, AC-DC conversion, power switching, and power supplies. The device features low power loss and high efficiency due to the low voltage drop across the diode when conducting. It also features a wide temperature range, allowing it to operate in harsh environments. The diode is packaged in a SOD-123FL package, allowing for better thermal management and improved system reliability.
