Overview
The MMBD4148SE is a small signal switching diode manufactured by onsemi, housed in an SOT-23-3 surface-mount package. It features a dual configuration with a peak reverse voltage of 100 V and a maximum continuous forward current of 200 mA. The device exhibits a fast recovery time of 4 ns and a low forward voltage of 1 V at rated current. Reverse leakage current is specified at 5 uA, while the peak non-repetitive forward surge current reaches 2 A. Operating temperatures range from -55 C to +150 C, supporting high-conductance ultra-fast switching applications.
Feature Summary
- High-speed switching capability with ultra-fast recovery characteristics
- Dual diode configuration within a compact SMD footprint
- Low leakage current for efficient signal isolation
- Robust thermal performance suitable for wide temperature ranges
Applications
- Signal processing circuits requiring fast switching
- General-purpose rectification in low-power electronics
- Clamping and protection in high-speed digital interfaces
Procurement Notes
Verify the manufacturer designation carefully, as the model number indicates onsemi production despite the requested brand. Confirm the specific suffix matches the required packaging format, such as cut tape or reel, against the official datasheet. Ensure the component meets RoHS compliance standards if required by your assembly specifications. Cross-reference the part number alias MMBD4148SE_NL for accurate inventory matching.
Selection Notes
Select this component when a dual diode arrangement is necessary within a limited board space. The 100 V rating provides sufficient headroom for general signal applications. Consider the 4 ns recovery time for frequencies where standard diodes may introduce excessive delay. The SOT-23-3 package facilitates automated surface-mount assembly processes.
Part Context
This component belongs to the MMBD4148 series of high-conductance ultra-fast diodes. It shares electrical characteristics with variants like MMBD4148CA and MMBD4148CC, differing primarily in packaging or suffix designations. The series is designed for applications demanding rapid switching speeds and low capacitance in a miniature form factor.
Replacement Considerations
MMBD4148CA and MMBD4148CC are confirmed substitutes within the same product family. Verify pinout compatibility and package dimensions before substitution. Ensure the alternative variant meets the same 100 V and 200 mA ratings.
