Overview
The MMBD4148CA RFG is a small signal switching diode manufactured by Taiwan Semiconductor Corporation. It features a single diode configuration housed in an SOT-23-3 surface-mount package. Key electrical parameters include a peak reverse voltage of 100 V, a maximum forward current of 200 mA, and a surge current rating of 2 A. The device exhibits a fast recovery time of 4 ns with a typical forward voltage of 1 V at 10 mA and a reverse leakage current of 5 µA. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- High conductance design for efficient signal switching
- Ultra-fast recovery characteristics suitable for high-speed applications
- Compact SOT-23-3 surface-mount packaging for space-constrained designs
Applications
- General purpose switching circuits
- Signal demodulation
- Clamping and protection applications
Procurement Notes
Verify the specific suffix 'RFG' against the official Taiwan Semiconductor datasheet to confirm exact binning or tape-and-reel specifications. Ensure the component matches the required RoHS compliance status and moisture sensitivity level for your assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a single diode with 100 V reverse voltage and 200 mA forward current is required in a compact SOT-23 package. Consider the 4 ns recovery time for high-frequency switching needs. Compare with other manufacturers like onsemi or Nexperia if alternative sourcing is necessary, ensuring pinout compatibility and thermal performance meet system requirements.
Part Context
This component belongs to the MMBD4148 series of small signal switching diodes. The series is widely used in consumer electronics and industrial equipment for general-purpose rectification and switching. The CA variant typically denotes specific electrical tolerances, while RFG indicates the packaging format. It serves as a standard replacement for legacy through-hole diodes in modern surface-mount designs.
Replacement Considerations
Verified substitutes include MMBD4148CC from onsemi and MMBD4148 from Nexperia. These alternatives share similar electrical characteristics and SOT-23-3 packaging. Verify that the substitute's forward voltage and reverse leakage current fall within acceptable limits for the specific application circuit.
