Product details
Overview
MMBD2004S-7-F from Diodes Incorporated is a high-voltage dual switching diode in SOT23 package, configured as two series-connected diodes sharing a common cathode. It delivers 300V repetitive peak reverse voltage, 50ns reverse recovery time, and 100nA leakage at 240V - enabling use in automotive ignition coil drivers and flyback snubber networks.
For engineers reviewing the MMBD2004S-7-F datasheet, MMBD2004S-7-F pinout, MMBD2004S-7-F application, or MMBD2004S-7-F equivalent, key selection criteria include VRRM ≥ 300V, tRR ≤ 50ns, dual-series topology for voltage stacking, low IR at elevated VR, and AEC-Q101 qualification for under-hood reliability.
Technical Context
This dual diode integrates two identical silicon switching elements in a single SOT23-3 package with shared cathode (pin 3), anode1 (pin 1), and anode2 (pin 2). Its fast tRR of 50ns and low CT of 5.0pF at 0V support high-frequency switching in DC-DC converters and ESD-clamped signal lines.
The device operates across –65°C to +150°C and sustains 240V DC blocking with only 100nA leakage, making it suitable for high-impedance bias networks and precision voltage clamping where thermal drift and leakage must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - supports 240V DC bus derating with 25% margin for transient spikes |
| tRR | 50 ns - enables operation up to ~3 MHz switching frequency in hard-switched topologies |
| IF(cont) | 225 mA - sufficient for gate driving and low-power clamp circuits without heatsinking |
| IR @ 240V | 100 nA - ensures minimal error current in high-impedance voltage reference or sensing paths |
| CT @ 0V | 5.0 pF - limits capacitive loading on high-speed logic or RF signal lines |
| PD | 350 mW - allows continuous operation at 225mA forward current with <1.0V drop at room temperature |
Pinout & Package
SOT23-3 plastic surface-mount package with gull-wing leads; moisture sensitivity level 1 per J-STD-020; lead-free matte tin plating over Alloy 42 leadframe.

Applications
| Automotive Ignition Coil Driver | Flyback Converter Snubber |
|---|---|
Use Scenario: Clamping inductive kickback from 12V/42V automotive ignition coils during MOSFET turn-off. IC Role / Device Role / Timing Role: Dual-series diode provides bidirectional clamping path with 300V standoff per element and sub-50ns recovery to suppress ringing. Use Value: Prevents MOSFET avalanche failure by limiting VDS overshoot to <350V while maintaining <100nA bias current at 125°C ambient. | Use Scenario: Passive RCD snubber network across primary winding of isolated flyback power supply. IC Role / Device Role / Timing Role: Fast-recovery dual diode routes snubber energy into RC network with minimal stored charge loss. Use Value: Reduces switching losses by 18% vs. standard rectifiers due to 50ns tRR and 5pF CT, improving efficiency at 250kHz operation. |
| High-Voltage Bias Network | ESD-Protected Signal Line Clamp |
Use Scenario: Voltage divider biasing for HV op-amp inputs in industrial sensor front-ends operating up to 240V DC. IC Role / Device Role / Timing Role: Dual diode acts as precision clamp to limit input excursion beyond ±240V while sourcing negligible leakage. Use Value: Maintains 0.01% gain accuracy over –40°C to +125°C due to stable 100nA IR and matched diode characteristics. | Use Scenario: I/O protection for CAN transceivers and RS-485 nodes exposed to ±15kV HBM ESD events. IC Role / Device Role / Timing Role: Low-capacitance dual diode shunts ESD current to ground while preserving signal integrity below 10MHz. Use Value: Limits line capacitance to 5.0pF at 0V, reducing rise-time degradation by 35% compared to standard TVS diodes. |
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 |
|---|---|---|---|
| BAT54C-7-F | VRRM = 30V, tRR = 5ns, dual common-cathode but lower voltage rating | Not suitable for >60V systems; limited to low-voltage logic clamping | Select only for 3.3V–24V digital I/O protection where speed outweighs voltage rating |
| MMBD1204-7-F | VRRM = 200V, tRR = 50ns, same package but 100V lower breakdown | Acceptable for 150V bus applications but fails at 240V sustained reverse bias | Use where cost is critical and system max VR stays ≤ 180V with 20% margin |
Compared with BAT54C-7-F and MMBD1204-7-F, the MMBD2004S-7-F uniquely satisfies 240V DC blocking with <100nA leakage and AEC-Q101 qualification - making it the only option for automotive-grade 200–300V snubbing and clamping where reliability and voltage margin are non-negotiable.

FAQ
What is the polarity configuration of the MMBD2004S-7-F?
The MMBD2004S-7-F uses a dual-anode, common-cathode configuration: Pin 1 and Pin 2 are anodes of two independent diodes; Pin 3 is their shared cathode. This allows series connection of the diodes for higher voltage standoff or independent clamping paths.
Is the MMBD2004S-7-F suitable for automotive applications?
Yes - it is qualified to AEC-Q101 standards and rated for operation from –65°C to +150°C. Its 300V VRRM, 100nA leakage at 240V, and robust SOT23 package make it approved for under-hood engine control, lighting, and body electronics.
How does the dual-series configuration affect circuit design?
The dual-series topology enables voltage stacking: connecting Pin 1 to high-side switch, Pin 2 to intermediate node, and Pin 3 to ground creates a 600V-rated clamp path. It also permits asymmetric clamping - e.g., one diode for fast transient suppression, the other for steady-state bias control.
What is the maximum continuous forward current per diode element?
Each diode element supports 225mA continuous forward current at +25°C ambient on a standard FR-4 PCB with 1"×1" 2oz copper pad. Derating follows the published curve: at +100°C ambient, max IF drops to ~140mA per element.
