Product details
Overview
SDM02M30LP3-7B from Diodes Incorporated is a Schottky barrier diode optimized for ultra-low forward voltage (0.45 V @ 10 mA), very low reverse leakage (0.4 µA @ 30 V), and compact DFN-0603 packaging (0.6 mm × 0.3 mm). It serves as a clamping, freewheeling, or reverse-polarity protection device in space-constrained portable electronics.
For engineers reviewing the SDM02M30LP3-7B datasheet, SDM02M30LP3-7B pinout, SDM02M30LP3-7B application, or SDM02M30LP3-7B equivalent, key selection criteria include its 30 V peak reverse voltage, 100 mA average forward current rating, sub-2 ns reverse recovery time, and cathode-bar-marked two-terminal configuration in X3-DFN0603-2 package.
Technical Context
This Schottky diode leverages a low-barrier metal-semiconductor junction to achieve fast switching (tRR = 1.6 ns) and minimal conduction loss. Its design targets high-efficiency DC-DC conversion stages and signal-level clamping where low VF and low CT (2.7 pF @ 5 V) are critical.
The device operates across –55°C to +150°C with thermal resistance θJA = 500°C/W on FR-4, and maintains stable leakage (<0.15 µA @ 30 V, 125°C) and forward voltage (<0.45 V @ 10 mA) over temperature - enabling reliable use in thermally dense mobile PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - maximum blocking voltage before breakdown; suitable for 3.3 V/5 V rail protection and USB-powered circuits |
| IO | 100 mA - continuous forward current capability; supports backlight LED strings and low-power logic clamping |
| VF max | 0.45 V @ 10 mA - low conduction loss reduces power dissipation and self-heating in battery-operated devices |
| IR max | 0.4 µA @ 30 V - ultra-low leakage preserves battery life in always-on standby paths |
| tRR | 1.6 ns - enables high-frequency switching in boost converters and ESD clamp response |
| CT | 2.7 pF @ 5 V - minimal junction capacitance avoids signal distortion in RF or high-speed data line protection |
| θJA | 500 °C/W - thermal performance validated on standard FR-4 layout; requires minimal copper area for thermal management |
Pinout & Package
Encapsulated in the X3-DFN0603-2 package (0.6 mm × 0.3 mm, 0.18 mm² footprint, 0.3 mm profile), this leadless surface-mount diode features a two-terminal configuration with cathode identified by a bar marking on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to higher-potential node (e.g., supply rail or switch node); no internal marking - determined by cathode bar orientation |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with visible bar; ties to lower-potential node (e.g., ground or load return); defines polarity-sensitive placement during layout |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small DFN-0603 footprint | 0.18 mm² area saves >70% board space vs. SOD-123; enables dual-diode placement in same area as one traditional package |
| Low forward voltage | 0.41 V typical @ 10 mA reduces I²R loss by ~40% vs. standard silicon diodes, extending battery runtime |
| Sub-2 ns reverse recovery | 1.6 ns tRR minimizes switching loss and ringing in 1–10 MHz DC-DC controllers |
| Low junction capacitance | 2.7 pF at 5 V prevents loading of high-speed signal lines (e.g., USB D+/D−, I²C) |
| Lead-free & halogen-free | Meets RoHS 2 and JEDEC J-STD-020 Level 1 moisture sensitivity; compatible with lead-free reflow profiles |
Applications
| Portable Device Power Management | LCD Backlight Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Higher VF (0.55 V @ 100 mA), larger SOD-523 package (1.2 mm × 0.8 mm) | Less suitable for ultra-dense layouts; acceptable where 0.1 V higher drop is tolerable | Select when legacy SOD-523 footprint compatibility is required and space constraints are relaxed |
| NSR0230HT1G | Same VRRM/IO, but 0.5 V VF max and 5 pF CT; SOD-923 package (1.0 mm × 0.6 mm) | Higher capacitance limits use in >5 MHz switching or high-speed data lines | Prefer for cost-sensitive designs where 2.7 pF CT is not mandatory and 0.45 V VF is non-critical |
Compared with RB521S-30T2R and NSR0230HT1G, SDM02M30LP3-7B delivers the lowest combined VF/CT/size trade-off - critical for next-generation compact battery-powered systems demanding minimal voltage loss and signal integrity.

FAQ
What is the cathode identification method for SDM02M30LP3-7B?
The cathode is marked by a visible bar on the top surface of the X3-DFN0603-2 package. This bar aligns with the cathode terminal in the mechanical drawing - confirmed in Diodes' DS35377 Rev. 8-2, page 1 (top view diagram) and page 4 (marking information section).
Does SDM02M30LP3-7B support reflow soldering per IPC-J-STD-020?
Yes - it is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to unlimited floor life and standard lead-free reflow profiles (peak 260°C) without baking. The matte tin finish on copper leadframe ensures reliable solder wetting.
Can SDM02M30LP3-7B replace a standard 1N5817 in a 5 V buck converter?
No - while both are Schottky diodes, the 1N5817 has 20 A IFSM and 1 A IO, whereas SDM02M30LP3-7B is rated only for 100 mA IO and 2 A surge. It is unsuitable for power-conversion outputs above ~100 mW; use only in signal-level or low-current auxiliary paths.
Is SDM02M30LP3-7B compliant with automotive AEC-Q200?
No - Diodes Incorporated does not qualify SDM02M30LP3-7B to AEC-Q200. It is specified for commercial and industrial temperature ranges (–55°C to +150°C), but lacks the stress testing, lot traceability, and failure analysis reporting required for automotive qualification.
