Product Overview
International Rectifier MBRS1100TR is a surface-mount Schottky barrier power rectifier in a DO-214AA (SMB) package. Engineered for low forward voltage drop and fast switching, it provides high-frequency rectification and reverse polarity protection in compact power circuits.
Key Features
- 1.0 A average forward rectified current
- 100 V peak repetitive reverse voltage rating
- 0.62 V forward voltage drop at 1.0 A (TJ = 125 °C)
- JEDEC DO-214AA (SMB) surface-mount package
- 150 °C maximum operating junction temperature
- Cathode band indicates polarity
Applications
- Secondary rectification and freewheeling diode protection in switch-mode power supplies
- Reverse polarity clamping on custom microcontroller and maker development boards
- High-frequency DC-DC buck and boost converter stages
Frequently Asked Questions
What does the cathode band on the body indicate?
The laser-marked bar indicates the cathode terminal of the diode, designating current flow direction.
What is the primary difference between MBRS1100 and standard silicon rectifiers?
Schottky barrier construction delivers a lower forward voltage drop and negligible reverse recovery time compared to standard PN junction rectifiers.
Is DO-214AA interchangeable with standard SMB footprints?
Yes. DO-214AA is the JEDEC standard package designation for SMB surface-mount footprints.
A dependable 100-volt Schottky diode keeps power moving in the right direction without burning up valuable voltage overhead. Drop it onto the board, solder the pads, and let your power rail run clean.
