Product details
Overview
SDM02L30CP3 from Diodes Incorporated is a 30 V, 200 mA Schottky barrier diode in a chip-scale package (X3-WLB0603-2), optimized for ultra-low forward voltage (0.44 V max at 200 mA) and low leakage (120 µA max at 30 V). It serves as a blocking or reverse-polarity protection diode in space-constrained portable power rails.
For engineers reviewing the SDM02L30CP3 datasheet, SDM02L30CP3 pinout, SDM02L30CP3 application, or SDM02L30CP3 equivalent, key selection criteria include its 0.18 mm² footprint, 0.275 mm profile, thermal resistance (250 °C/W), soft switching behavior, and RoHS-compliant NiAu bump terminals.
Technical Context
This Schottky diode uses a planar metal–semiconductor junction to achieve fast, soft recovery with no minority-carrier storage delay. Its low VF minimizes conduction loss in low-voltage DC/DC output stages and battery protection circuits.
The X3-WLB0603-2 package features two solderable NiAu bumps on a silicon die, enabling direct board mounting with minimal parasitic inductance. Thermal performance is defined under JEDEC-standard FR-4 layout with specified pad dimensions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse voltage before breakdown; sets safe operating limit in 3.3 V or 5 V rail protection |
| IO | 200 mA - Continuous forward current rating; suitable for USB-powered peripherals and sensor nodes |
| VF Max | 0.44 V @ 200 mA - Low conduction loss enables >95% efficiency in 3.3 V buck converter output stage |
| IR Max | 120 µA @ 30 V - Minimal leakage preserves battery runtime in always-on IoT devices |
| RθJA | 250 °C/W - Thermal resistance measured on FR-4 with recommended pads; requires derating above +70°C ambient |
| Junction Cap | 10 pF @ 5 V - Low capacitance avoids signal integrity issues in high-frequency boost converters |
| Package | X3-WLB0603-2 - 0.6 mm × 0.3 mm CSP with 0.275 mm height; compatible with standard 0201 reflow profiles |
Pinout & Package
The SDM02L30CP3 uses a 2-terminal chip-scale package (X3-WLB0603-2) with NiAu solder bumps. Polarity is marked by a cathode dot on the top surface. No leadframe or wire bonds are present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Bump 1) | Forward current entry point | Connected to input rail or switch node; requires thermal relief on high-current traces |
| Cathode (Bump 2, dot-marked) | Forward current exit / reverse voltage reference | Connected to load or ground; cathode dot must align with PCB silkscreen indicator |
Key Features
| Feature | Design Value |
|---|---|
| 0.18 mm² footprint | Reduces PCB area by >50% vs. SOD-523; enables dense wearable PCB layouts |
| Soft, fast switching | No reverse recovery tail; eliminates ringing in 1–2 MHz DC/DC converters |
| NiAu bump terminations | Compatible with Pb-free reflow (260°C peak); eliminates intermetallic growth concerns |
| Halogen & antimony free | Meets IEC 61249-2-21; supports green compliance for EU medical and industrial products |
Applications
| USB Power Input Protection | Wearable Battery Charging Path |
|---|---|
Use Scenario: Prevents reverse current flow from battery to dead USB port during charging circuit fault. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed between USB VBUS and PMIC input. Use Value: 0.44 V VF drop limits power loss to <90 mW at 200 mA, preserving charging efficiency. | Use Scenario: Blocks battery discharge back into a disabled charger IC when system is powered off. IC Role / Device Role / Timing Role: Blocking diode in linear charger path for Li-ion coin cells. Use Value: 120 µA IR at 3.6 V ensures <0.5 µA average leakage over 10-year shelf life. |
| Low-Power Sensor Node Rail | Boost Converter Output Rectifier |
Use Scenario: Isolates main MCU rail from auxiliary sensor supply to prevent cross-talk during sleep mode. IC Role / Device Role / Timing Role: Rail isolation diode in energy-harvesting sub-system. Use Value: 0.23 V VF at 10 mA enables stable 1.8 V rail delivery from 2.2 V harvester output. | Use Scenario: Rectifies switched output in 1.2 MHz boost converter powering BLE radio. IC Role / Device Role / Timing Role: High-frequency synchronous rectifier replacement. Use Value: 10 pF CT and soft switching reduce EMI emissions by 8 dB compared to standard SOD-323 Schottky. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | Higher VF (0.55 V @ 200 mA); SOD-523 package (0.6 mm × 0.3 mm, same footprint) | Less efficient in battery-critical paths due to +110 mV VF penalty | Prefer when existing SOD-523 layout cannot be modified and leakage <50 µA is acceptable |
| NSR0230P2T5G | Lower IR (2 µA @ 30 V); same VF (0.44 V); slightly larger 0.8 mm × 0.4 mm footprint | Better for long-term storage but requires 2.2× more board area | Choose when ultra-low leakage dominates over size constraints, e.g., implantable sensors |
Compared with RB520S-30T2R and NSR0230P2T5G, SDM02L30CP3 uniquely balances minimal footprint (0.18 mm²), industry-low VF at 200 mA, and certified halogen-free compliance-making it optimal for next-gen wearables where space, efficiency, and environmental specs are jointly critical.

FAQ
What is the maximum junction temperature for continuous operation?
The SDM02L30CP3 has a rated operating junction temperature range of –55°C to +150°C. For continuous 200 mA operation, thermal design must ensure TJ stays below 150°C-typically requiring ambient ≤ +70°C with the JEDEC FR-4 pad layout and no additional heatsinking.
Is the X3-WLB0603-2 package compatible with standard 0201 pick-and-place equipment?
Yes-the X3-WLB0603-2 package (0.6 mm × 0.3 mm) matches the outer dimensions of JEDEC-standard 0201 passives. Its NiAu bumps are compatible with standard vacuum nozzles and vision alignment systems calibrated for 0201 components.
How does the soft switching behavior affect EMI in DC/DC converters?
Soft switching eliminates reverse recovery current spikes, reducing high-frequency harmonics above 30 MHz. In 1–2 MHz boost converters, this lowers radiated EMI by up to 8 dB compared to conventional Schottky diodes with abrupt turn-off characteristics.
Can SDM02L30CP3 replace a standard 1N5819 in a 5 V supply rail?
No-it is rated for only 30 V VRRM and 200 mA IO, whereas 1N5819 handles 40 V and 1 A. Substitution is valid only in low-current, ≤30 V applications such as USB 2.0 VBUS protection or coin-cell backup paths-not mains-derived 5 V rails.
