Product details
Overview
SDM02M30DCP3 from Diodes Incorporated is a 30V dual common-cathode Schottky barrier diode optimized for low leakage (2 µA @ 30V), low forward voltage (750 mV max @ 200 mA), and ultra-compact X3-DSN1006-3 package (0.6 mm² footprint, 0.275 mm profile). It serves as a reverse polarity protection and boost diode in space-constrained portable power rails.
For engineers reviewing the SDM02M30DCP3 datasheet, SDM02M30DCP3 pinout, SDM02M30DCP3 application, or SDM02M30DCP3 equivalent, key selection criteria include its 2 µA max reverse leakage at 30 V, 7 pF junction capacitance at 1 V, 2.99 ns reverse recovery time, thermal resistance of 200 °C/W, and compatibility with high-density PCB layouts requiring minimal board area.
Technical Context
This dual Schottky diode integrates two independent anode terminals sharing a single cathode terminal in a monolithic die structure. Its low RθJA (200 °C/W) enables operation up to +150 °C junction temperature without derating under typical FR-4 mounting conditions.
The device delivers soft, fast switching with tRR = 2.99 ns and CJ = 7 pF at 1 V, supporting high-frequency DC-DC converter topologies where low stored charge and minimal capacitive loading are critical for efficiency and EMI control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before breakdown; suitable for 24 V system inputs with margin. |
| IO (total) | 400 mA - Continuous average current per diode pair; supports compact USB-C PD auxiliary power paths. |
| VF max | 750 mV @ 200 mA - Low conduction loss reduces thermal load in battery-fed applications. |
| IR max | 2 µA @ 30 V - Enables multi-year battery life in always-on IoT sensors by minimizing standby drain. |
| CJ | 7 pF @ 1 V - Limits high-frequency coupling in RF-adjacent power domains and improves switching node stability. |
| tRR | 2.99 ns - Enables clean turn-off in >1 MHz synchronous rectifiers without voltage spikes. |
| RθJA | 200 °C/W - Allows direct mounting on small copper pads without thermal vias in wearables. |

Applications
| USB Power Delivery Protection | Wireless Charging Receiver |
|---|---|
Use Scenario: Prevents reverse current flow from VBUS to dead battery or faulty port during hot-plug events in USB-C accessories. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed between connector and buck converter input. Use Value: 2 µA leakage preserves battery charge over months of standby; 750 mV VF limits dropout to <1% at 200 mA. | Use Scenario: Blocks reverse current from Qi receiver coil output into charging IC when transmitter is inactive. IC Role / Device Role / Timing Role: Synchronous rectifier freewheeling diode in full-wave rectifier stage. Use Value: 2.99 ns tRR prevents shoot-through in 200–500 kHz resonant converters; 7 pF CJ avoids detuning of LC tank. |

IC Role / Device Role / Timing Role: Common-cathode dual diode enabling seamless source selection without controller intervention. Use Value: Dual-anode layout eliminates need for two discrete diodes; 0.6 mm² saves >0.8 mm² board area vs. two DFN0603s. | Use Scenario: Input protection for 24 V loop-powered field transmitters exposed to transient surges. IC Role / Device Role / Timing Role: Blocking diode isolating analog front-end from supply rail during fault conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (850 mV @ 200 mA), larger SOD-323 package (1.7 mm²), 5 µA IR | Less suitable for sub-1 mm² layouts; higher leakage reduces battery life in always-on nodes. | Choose only if legacy SOD-323 footprint reuse is required and leakage tolerance >5 µA. |
| NSR20F30NXT5G | Same X3-DSN1006-3 package, but 300 mV lower VF (450 mV @ 200 mA); 10 µA IR | Better efficiency in high-current boost stages, but 5× higher leakage compromises long-term storage. | Select when peak efficiency > battery shelf life; verify IR impact on 10+ year deployments. |
Compared with RB050M-30 and NSR20F30NXT5G, SDM02M30DCP3 uniquely balances ultra-low leakage (2 µA), compact size (0.6 mm²), and moderate VF (750 mV), making it optimal for battery-critical, space-constrained portable designs where both standby life and board area are tightly constrained.

FAQ
What is the maximum continuous current rating per diode in SDM02M30DCP3?
The SDM02M30DCP3 is rated for 400 mA average rectified output current total across both diodes. Each diode supports up to 200 mA continuous DC current under standard FR-4 mounting conditions with no forced airflow, based on thermal derating curves in DS39324 Rev. 5–2.
Does SDM02M30DCP3 have AEC-Q200 qualification for automotive use?
No-SDM02M30DCP3 is not AEC-Q200 qualified. The datasheet explicitly states that automotive-grade versions require separate qualification (AEC-Q100/101/200), PPAP capability, and IATF 16949 manufacturing; this part is intended for commercial portable and industrial applications only.
How is polarity identified on the SDM02M30DCP3 package?
Polarity is marked by a cathode bar on the top surface aligned with Pin 2 (common cathode). The marking matches the top-view diagram in DS39324: Pin 1 (anode 1) and Pin 3 (anode 2) flank the central cathode bar, which overlays Pin 2. No silkscreen or laser marking is used-only the physical bar feature.
Can SDM02M30DCP3 replace a single discrete Schottky diode in a design?
Yes-but only if the circuit uses only one of the two anodes and ties the unused anode to cathode or leaves it floating. Using only one diode forfeits the dual functionality but retains all electrical specs (VF, IR, CJ) for that channel; layout must still accommodate the 3-pin footprint.
