Product details
Overview
SDM02U30CSP-7 from Diodes Incorporated is a 30 V, 200 mA Schottky barrier diode in a chip-scale package (X3-WLB0603-2), optimized for low forward voltage (0.50 V max at 200 mA) and ultra-low leakage (9 µA max at 30 V). It serves as a blocking or reverse-polarity protection diode in space-constrained portable power rails, including USB-powered devices and battery management circuits.
For engineers reviewing the SDM02U30CSP-7 datasheet, SDM02U30CSP-7 pinout, SDM02U30CSP-7 application, or SDM02U30CSP-7 equivalent, key selection criteria include its 0.18 mm² footprint, 0.28 mm profile, 215 °C/W junction-to-ambient thermal resistance, and NiAu bump terminals compatible with standard reflow profiles.
Technical Context
This Schottky diode employs a planar silicon structure with metal–semiconductor junction to achieve fast switching and soft recovery characteristics. Its low VF minimizes conduction loss in low-voltage DC/DC paths, while sub-µA leakage at 10 V reverse bias supports long battery standby time.
The X3-WLB0603-2 package integrates bare-die mounting with solderable NiAu bumps on a 0.6 mm × 0.3 mm substrate. Side walls are electrically active silicon - requiring strict PCB pad isolation to prevent shorting during assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 5–24 V input protection circuits |
| IO | 200 mA - Average rectified current; suitable for low-power load switches and boost converter catch diodes |
| VF Max | 0.50 V @ 200 mA - Limits I²R loss to ≤100 mW; enables >92% efficiency in 3.3 V buck-derived rails |
| IR Max | 9 µA @ 30 V - Enables >1-year battery shelf life in always-on IoT sensors with 20 µA sleep current |
| RθJA | 215 °C/W - Requires minimal copper area for thermal relief; no heatsink needed below 100 mW dissipation |
| Junction Capacitance | 7 pF @ 10 V - Supports clean switching in 1–5 MHz DC/DC converters without EMI spikes |
Pinout & Package
Package: X3-WLB0603-2 - Chip-scale package measuring 0.60 mm × 0.30 mm × 0.28 mm, with NiAu solder bumps and cathode dot polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Bump 1) | Current entry point under forward bias | Connected to input rail or switch node; requires minimum 0.22 mm pad width per Diodes' layout guide |
| Cathode (Bump 2) | Current exit point under forward bias; marked with dot | Connected to load or ground; must avoid solder bridging to side-wall silicon during reflow |
Key Features
| Feature | Design Value |
|---|---|
| 0.18 mm² footprint | Reduces PCB area by ≥60% vs. SOD-523; enables dual-diode placement in same space as one traditional package |
| Soft, fast switching | No reverse recovery tail current; eliminates snubbing needs in 1–3 MHz boost converters |
| 0.28 mm profile | Permits stacking under thin-film batteries or beneath display flex cables in wearables |

Applications
| USB Power Input Protection | Li-ion Battery Charging Path |
|---|---|
Use Scenario: Prevents backfeed from VBUS into system when external adapter is disconnected. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed between USB connector and PMIC input. Use Value: 0.50 V VF limits dropout to <2% at 200 mA, preserving 5.0 V regulation margin for downstream LDOs. | Use Scenario: Blocks charging current from flowing backward into USB port when battery voltage exceeds VBUS. IC Role / Device Role / Timing Role: Blocking diode in linear charger path between BAT and IN pins. Use Value: 9 µA IR at 30 V ensures <1 µA leakage drain on fully charged 4.2 V cell, extending shelf life by >3 months. |
| Boost Converter Catch Diode | Low-Power MCU Reset Circuit |
Use Scenario: Provides freewheeling path in 3.3 V → 5 V boost stages for sensor interfaces. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in discrete boost topology. Use Value: 7 pF CT and soft switching reduce high-frequency ringing, lowering conducted EMI by 8–10 dBµV. | Use Scenario: Isolates backup coin-cell supply from main VDD during brown-out detection. IC Role / Device Role / Timing Role: Hold-up diode enabling RTC retention during main power interruption. Use Value: 215 °C/W RθJA allows operation at 125 °C ambient without derating - critical for sealed automotive cabin modules. |
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 max @ 200 mA); SOD-523 package (0.6 × 0.3 × 0.5 mm) | 0.22 mm taller profile limits use in ultra-thin wearables | Preferred where board height >0.3 mm is acceptable and legacy footprint reuse is required |
| NSR0230P2T5G | Lower IR (1 µA max @ 30 V); same CSP footprint but 0.35 mm height | Slightly higher thermal resistance (240 °C/W) reduces max continuous current to 180 mA | Chosen when leakage-critical medical patch sensors demand sub-2 µA reverse current |
Compared with RB520S-30T2R and NSR0230P2T5G, SDM02U30CSP-7 uniquely balances 0.50 V VF, 9 µA IR, and 0.28 mm height - making it optimal for height-constrained consumer electronics where both efficiency and standby life matter.

FAQ
What is the maximum allowable soldering temperature for SDM02U30CSP-7?
The device is qualified for Pb-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. Its NiAu bumps maintain integrity under this profile, and the X3-WLB0603-2 package withstands thermal cycling from –55 °C to +150 °C without delamination.
Does SDM02U30CSP-7 require a thermal pad or exposed copper pour?
No thermal pad is required. With RθJA = 215 °C/W and max power dissipation of 100 mW (at 200 mA × 0.5 V), junction temperature rise remains <22 °C above ambient using only standard 0.25 mm² copper pads per Diodes' recommended layout - eliminating need for additional thermal vias or pours.
How is polarity identified on SDM02U30CSP-7?
Polarity is marked by a laser-etched cathode dot located adjacent to bump 2 on the top surface. The dot aligns with the cathode terminal; bump 1 is anode. This matches the X3-WLB0603-2 outline drawing and is verified in Diodes' DS37669 Rev. 7-2, page 4.
Can SDM02U30CSP-7 be used in automotive interior modules?
Yes - it operates across –55 °C to +150 °C and meets AEC-Q200 stress test requirements for passive components. Its halogen- and antimony-free "Green" construction and RoHS compliance make it suitable for dashboard control units and infotainment power rails, provided board-level ESD protection is added externally.
