MMBD4148TW-7-F

Overview

The MMBD4148TW-7-F is a surface mount fast switching diode array manufactured by Diodes Incorporated. It features three independent diodes in an SOT363 package. Key electrical parameters include a maximum DC blocking voltage of 75 V, a continuous forward current of 300 mA, and a reverse recovery time of 4 ns. The device dissipates up to 200 mW of power and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Fast switching speed with low capacitance for high-frequency applications
• Ultra-small SOT363 surface mount package design
• High conductance characteristics
• Totally lead-free and fully RoHS compliant construction

Applications

• General purpose switching circuits
• High-speed signal processing
• Automotive electronics (requires BAS16TWQ variant)

Procurement Notes

Verify the specific ordering suffix matches the required packing quantity and carrier type. Confirm that the component meets all applicable environmental directives relevant to the target market. Ensure the supplier provides valid traceability documentation for the manufacturing date code and lot number.

Selection Notes

Select this component when a triple diode configuration is required in a compact footprint. Consider the 75 V reverse voltage rating and 300 mA forward current limits against circuit demands. Evaluate the thermal resistance and power dissipation capabilities relative to the PCB layout and ambient operating conditions.

Part Context

This part belongs to the MMBD4148TW / BAS16TW series of surface mount fast switching diode arrays. It shares functional similarities with single-diode variants but integrates three elements into one package. The series is designed for general-purpose switching applications requiring small form factors.

Replacement Considerations

BAS16TW-7-F is a direct substitute within the same series. Verify pinout compatibility and electrical ratings before substitution. Other packages or manufacturers require full parameter validation.
