Schottky diodes are available in two package types: one is a plug-in package and the other is a chip package. Plug-In Package Dual In-line Package referred to as DIP, such as common models 1N5819, MBR10100, SR160, etc .; SMD SMD Surface Mounted Devices referred to SMD, such as commonly used models B5819W, SS16, BAT54.

We can identify the package shape by model:

MBR10100: TO-220AC, Single Chip, Two Pins

MBR10100CT: TO-220AB, dual chip, three-pin, model suffix with CT;

MBRB10100CT: TO-263 (D2PAK) patch;

The fourth letter in front of the model B, on behalf of TO-263, internationally nomenclature;

MBRD1045CT: TO-252 (DPAK), SMD,

MBRD and MBRB are patches, D: TO-252, B: TO-263,

MBR3045PT: TO-3P, model suffix "PT" stands for TO-3P package,

The original MOTOROLA (now ON) called SOT-93,

SBD1045: D for TO-251.

Common SMD package Schottky Model:

MBR0520L, MBR0540: SOD-123, 0.5A

SS12, SS14: DO-214AC (SMA), 1A

SL12, SL14: DO-214AC (SMA), 1A

SK22, SK24: DO-214AA (SMB), 2A

       Schottky diode, also known as Schottky barrier diode (SBD), it is a low-power, ultra-high-speed semiconductor devices. The most significant feature of the reverse recovery time is very short (as small as a few nanoseconds), the forward voltage drop of only 0.4V or so. Its multi-purpose for high-frequency, low voltage, high current rectifier diodes, freewheeling diodes, protection diodes, but also useful in microwave communications and other circuits for rectifier diodes, small signal detection diode. In communications power supply, inverter and other more common.
