Product details
Overview
MMBD2004SW-7-F from Diodes Incorporated is a high-voltage dual switching diode in SOT323 package, rated for 300 V repetitive peak reverse voltage, 225 mA forward current, and 50 ns reverse recovery time. It serves as a fast, low-leakage signal or power path switch in automotive and industrial DC-DC converters, ESD protection circuits, and high-side sensing interfaces.
For engineers reviewing the MMBD2004SW-7-F datasheet, MMBD2004SW-7-F pinout, MMBD2004SW-7-F application, or MMBD2004SW-7-F equivalent, key selection criteria include reverse breakdown voltage, trr timing under 30 mA switching conditions, leakage at 240 V bias, thermal resistance (500 °C/W), and AEC-Q101 qualification status.
Technical Context
This dual common-cathode diode integrates two independent silicon junctions in one compact SOT323 package. Each element supports 300 V VRWM, 225 mA IF, and exhibits <100 nA IR at 240 V and 25 °C.
The device uses planar epitaxial construction with low-capacitance junction design (5.0 pF at 0 V), enabling use in high-frequency switching and transient suppression where fast turn-off and minimal charge storage are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT54CW-7-F | Lower VRWM (30 V), faster trr (5 ns), higher leakage (1 µA @ 25 V) | Not suitable for >100 V blocking; limited to low-voltage logic-level switching | Select only when system voltage stays below 30 V and ultra-fast recovery is prioritized over blocking capability |
| MMBD1205S-7-F | Higher VRWM (400 V), same SOT323 package, slower trr (75 ns), higher leakage (200 nA @ 320 V) | Better for 400 V bus protection but less optimal in high-frequency snubbers due to longer recovery | Prefer for primary-side surge suppression where speed is secondary to voltage margin |
Compared with BAT54CW-7-F and MMBD1205S-7-F, MMBD2004SW-7-F uniquely balances 300 V blocking, 50 ns recovery, and sub-100 nA leakage-making it optimal for 24–240 V automotive and industrial switching nodes requiring both robustness and timing precision.
