Product details
Overview
SDM02U30LP3Q from Diodes Incorporated is an ultra-small surface-mount Schottky barrier diode optimized for low forward voltage (0.37 V max at 10 mA) and low reverse leakage (7 µA max at 10 V), housed in the X3-DFN0603-2 package (0.18 mm² footprint, 0.35 mm profile). It serves as a blocking or freewheeling diode in space-constrained portable electronics requiring efficient reverse voltage protection and minimal power loss.
For engineers reviewing the SDM02U30LP3Q datasheet, SDM02U30LP3Q pinout, SDM02U30LP3Q application, or SDM02U30LP3Q equivalent, key selection criteria include its 30 V peak reverse voltage rating, 100 mA average forward current capability, AEC-Q101 qualification for automotive use, and ultra-low-profile packaging suitable for high-density PCB layouts in battery-powered devices.
Technical Context
This Schottky diode employs a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve sub-0.4 V forward conduction at 10 mA while maintaining <7 µA leakage at 10 V reverse bias - critical for extending battery life in always-on subsystems. Its thermal resistance of 500 °C/W (junction-to-ambient, FR-4 board) and -55 °C to +150 °C operating range support reliable operation in compact, thermally limited environments.
The device is rated for 2 A non-repetitive surge current (8.33 ms half-sine), enabling robust transient handling during power-up or inductive switching events. Total capacitance is 1–10 pF across 0–30 V reverse bias (f = 1 MHz), making it suitable for high-frequency clamping and signal-level rectification without significant capacitive loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; defines safe DC blocking limit in power rail protection. |
| IO | 100 mA - Continuous average forward current; supports low-power LED backlighting and sensor biasing circuits. |
| VF (max) | 0.37 V @ 10 mA - Minimizes conduction loss in battery-fed paths; reduces heat generation in 0.18 mm² footprint. |
| IR (max) | 7 µA @ 10 V - Enables >1-year standby battery life in coin-cell–powered IoT sensors and wearables. |
| RθJA | 500 °C/W - Requires careful thermal pad layout per Diodes' recommended footprint to avoid junction overheating at full load. |
| Package | X3-DFN0603-2 - 0.62 × 0.32 mm body, 0.35 mm max height; compatible with standard 0201 reflow profiles and AOI inspection. |
Pinout & Package
Encapsulated in the X3-DFN0603-2 package: ultra-compact 2-terminal leadless plastic case with cathode bar marking on top surface. Terminals are matte tin-plated copper leadframe, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to higher-potential node (e.g., battery+, input rail); no internal connection to package pad. |
| Cathode (marked with bar) | Forward current exit / reverse blocking terminal | Connected to load or ground; exposed thermal pad is electrically tied to cathode - must be routed accordingly. |
Key Features
| Feature | Design Value |
|---|---|
| 0.18 mm² footprint | 70% smaller than DFN1006/SOD923 - enables routing under fine-pitch BGAs and dense RF modules. |
| 0.35 mm max profile | 30% thinner than DFN1006 - allows stacking of multiple PCB layers or integration into slim bezel assemblies. |
| 0.37 V VF (max) | Reduces forward power loss by ~40% vs. typical silicon diodes at 10 mA - critical for microampere-quiescent systems. |
| AEC-Q101 qualified | Validated for automotive cabin electronics (e.g., infotainment displays, sensor interfaces) with PPAP documentation support. |
| Halogen & antimony free | Meets IEC 61249-2-21 "Green" requirements (<900 ppm Br/Cl, <1000 ppm Sb) for eco-compliant consumer and medical end equipment. |
Applications
| Reverse Voltage Protection | LED Backlighting |
|---|---|
|
Use Scenario: Preventing damage from reversed battery insertion or hot-swap transients in USB-C powered accessories. IC Role / Device Role / Timing Role: Unidirectional current gate placed between power source and PMIC input. Use Value: 30 V VRRM withstands 5 V rail surges; 7 µA IR avoids measurable drain on lithium coin cells during storage. |
Use Scenario: Driving white LEDs in smartphone front-panel keypads and status indicators. IC Role / Device Role / Timing Role: Current-limiting series diode in constant-current LED string path. Use Value: 0.37 V VF minimizes voltage headroom loss, enabling full brightness from 2.8 V Li-ion cells. |
| Clamping Protection | Freewheeling Diode |
|
Use Scenario: Suppressing inductive kickback from small solenoids or relay coils in automotive door modules. IC Role / Device Role / Timing Role: Fast-turn-off clamp connected across coil terminals. Use Value: Sub-1 ns reverse recovery time (inherent to Schottky structure) prevents voltage overshoot beyond 30 V rating. |
Use Scenario: Recirculating current in low-duty-cycle DC-DC converter synchronous rectifiers. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side FET off-time. Use Value: 100 mA IO rating supports up to 500 kHz switching with <10 mW conduction loss at 10 mA average load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TE25 (ROHM) | Higher VF (0.45 V max @ 10 mA), larger SOD-523 (1.2 mm²) footprint, same 30 V VRRM. | Less suitable for ultra-thin wearables but offers higher surge rating (3 A IFSM). | Select when surge robustness outweighs size constraints and 80 mV higher VF is acceptable. |
| NSR0230HT1G (onsemi) | Same X3-DFN0603-2 package, identical 30 V/100 mA ratings, but VF = 0.42 V max @ 10 mA and IR = 10 µA @ 10 V. | Slightly higher leakage limits use in >5-year shelf-life medical sensors. | Choose if supply chain diversification is prioritized and 50 mV VF penalty is tolerable. |
Compared with RB050M-30TE25 and NSR0230HT1G, SDM02U30LP3Q delivers the lowest VF and smallest footprint among 30 V Schottky diodes in production, making it optimal for next-generation miniaturized battery management and display subsystems where every micron and millivolt matters.

FAQ
Is SDM02U30LP3Q suitable for automotive applications?
Yes - it is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. Its -55 °C to +150 °C operating temperature range, 30 V VRRM, and low leakage meet requirements for cabin electronics such as display biasing, sensor interface protection, and LED driver circuits in passenger vehicles.
What is the thermal pad connection on the X3-DFN0603-2 package?
The exposed thermal pad on the bottom of the X3-DFN0603-2 package is electrically connected to the cathode terminal. It must be soldered to a PCB copper pour tied to the cathode net to ensure proper thermal dissipation and electrical integrity - not left floating or grounded independently.
Does SDM02U30LP3Q have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, it exhibits majority-carrier conduction with no minority-carrier storage delay. Its effective switching is limited only by junction capacitance (1–10 pF) and package inductance, enabling sub-nanosecond turn-off behavior essential for high-frequency clamping and RF decoupling.
Can SDM02U30LP3Q replace a standard silicon diode in a 5 V USB power path?
Yes - with 30 V VRRM and 0.37 V VF, it provides superior efficiency over 1N4148 or BAS16 in 5 V paths, reducing voltage drop by ~0.4 V and conduction loss by >60%. However, verify that system-level reverse leakage tolerance accommodates its 7 µA max IR at 10 V.
