The MBRM120LT1G from onsemi is a 1A 20V Schottky rectifier with 0.34V forward voltage in SOD-123 package for low-voltage power supply rectification.

The MBRM120LT1G is a 1A 20V Schottky rectifier from onsemi in SOD-123 package. The MBR prefix stands for Motorla Bathtub Rectifier (legacy naming), and the M suffix indicates the SOD-123 mini-package. The Schottky diode uses a metal-semiconductor junction (typically chromium or platinum silicide on n-type silicon) rather than a PN junction. This gives it two key advantages: (1) Lower forward voltage drop (VF = 0.34V typical at 1A, vs 0.7V for a silicon PN diode), reducing power dissipation in rectification applications; (2) Zero reverse recovery time (no minority carrier storage), eliminating switching losses in high-frequency applications. The trade-off is higher reverse leakage current (0.5mA at 20V, 25C, increasing to 10mA at 75C) and lower breakdown voltage (limited to about 200V for Schottky devices). The SOD-123 package (2.7 x 1.6mm) is the smallest commonly available power diode package, with typical PCB footprint of 4mm x 2mm including solder pads. The 1A rating is at 25C case temperature, derating to approximately 0.5A at 75C. The junction-to-ambient thermal resistance is 140C/W on minimum PCB pad. Applications include: DC-DC converter free-wheeling diode, reverse polarity protection, OR-ing diode in redundant power supplies, and solar cell bypass diode. The -LT1G suffix specifies SOD-123, tape-and-reel, lead-free.
