Product details
Overview
PMEG3005ELD,315 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 0.5 A average forward current, 30 V reverse voltage rating, and ultra-low 450 mV typical forward voltage at 500 mA, housed in an AEC-Q101-qualified SOD882D leadless package with solderable side pads.
For engineers reviewing the PMEG3005ELD,315 datasheet, PMEG3005ELD,315 pinout, PMEG3005ELD,315 application, or PMEG3005ELD,315 equivalent, this device is selected for space-constrained automotive and industrial power rails where thermal efficiency, low VF, and board-level reliability under transient stress are critical design requirements.
Technical Context
This Schottky diode uses a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its low 450 mV VF at 500 mA directly reduces conduction loss in synchronous rectifier and flyback auxiliary winding applications.
Thermal performance is optimized for ultra-thin PCB mounting: Rth(j-sp) = 50 K/W to cathode solder point, and Rth(j-a) drops to 125 K/W on ceramic Al₂O₃ substrate-enabling stable operation up to 150 °C junction temperature in compact power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 0.5 A - Maximum continuous forward current at ≤75 °C ambient or ≤130 °C solder point, enabling use in 5 V/3.3 V buck converter outputs. |
| VR | 30 V - Maximum repetitive reverse voltage; suitable for 24 V automotive supply rails with margin against load dump transients. |
| VF @ 500 mA | 450 mV typ. - Low conduction loss improves efficiency by ~0.5–1.2% in 1–3 W DC-DC stages versus standard Schottkys. |
| IR @ 10 V | 15 μA typ. - Low leakage preserves battery life in always-on automotive modules (e.g., CAN wake-up circuits). |
| trr | 6 ns - Ultra-fast recovery minimizes switching loss and EMI in high-frequency (>500 kHz) SMPS designs. |
| Cd @ 1 V | 21 pF - Low junction capacitance supports clean turn-off in high-speed clamping and OR-ing applications. |
| Package | SOD882D - 1.0 × 0.6 × 0.37 mm leadless package with visible, solderable side pads; compatible with standard 2 mm pitch tape-and-reel (−315 variant). |
Pinout & Package
The SOD882D package is a 2-terminal, leadless surface-mount device with cathode (Pin 1) identified by a marking bar on the top surface and anode (Pin 2) as the opposite terminal. Side pads are fully solderable and electrically connected to respective die terminals-no internal leads or wire bonds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to PCB ground or negative rail; thermally coupled to large copper pour for heat extraction via side pads. |
| 2 | Anode | Input node for forward conduction path; side pad enables low-inductance connection to switching node in buck converters. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood applications per stress test requirements including HTGB, HTRB, and ESD-HBM ≥2 kV. |
| Integrated guard ring | Suppresses edge electric field concentration, raising VR surge withstand by ≥20% vs. non-guarded equivalents. |
| Ultra-low profile (0.37 mm) | Enables stacking under connectors or in height-critical modules such as USB-C PD adapters and automotive camera ECUs. |
| Solderable side pads | Provide dual-side thermal and electrical connection-reducing thermal resistance by up to 45% compared to top-only termination. |
| Low trr (6 ns) | Eliminates reverse recovery tail current, preventing shoot-through in synchronous rectifier control schemes. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | Higher VF (520 mV min @ 500 mA), same 30 V VR, SOD-523 package (1.2 × 0.8 mm), no guard ring. | Lacks AEC-Q101 qualification and surge robustness; unsuitable for automotive transients. | Select only for cost-sensitive consumer-grade 5 V rails where thermal margin exceeds 25 °C. |
| SS12-AU | Higher IF(AV) = 1 A, VF = 500 mV max @ 1 A, SMA package (4.5 × 2.7 mm), no side pads. | 3× larger footprint and 3.5× higher Rth(j-a); requires >200 mm² copper area for same thermal performance. | Choose when higher current headroom is needed and board space permits larger discrete packaging. |
Compared with RB520S-30T2R and SS12-AU, PMEG3005ELD,315 uniquely balances ultra-small size, AEC-Q101 compliance, and sub-450 mV VF-making it optimal for automotive and portable medical systems where volume, reliability, and efficiency are simultaneously constrained.

FAQ
What is the maximum allowable soldering temperature profile for PMEG3005ELD,315?
Reflow soldering is the only recommended method. Peak temperature must not exceed 260 °C for ≤10 seconds, with ramp-up ≤3 °C/s and ramp-down ≤6 °C/s. The SOD882D package is not rated for wave or hand soldering due to mechanical stress on side pads and die attach integrity.
Does PMEG3005ELD,315 support bidirectional current flow?
No. It is a unidirectional Schottky rectifier with fixed anode–cathode polarity. Forward conduction occurs only from anode (Pin 2) to cathode (Pin 1). Reverse bias blocks current up to 30 V; intentional reverse conduction will cause permanent junction damage.
How does the guard ring affect layout requirements?
The integrated guard ring requires ≥0.2 mm clearance from adjacent copper traces or planes on all sides of the SOD882D outline to prevent field crowding at the die edge. This is stricter than standard Schottkys and must be verified in Gerber stack-up review.
Can PMEG3005ELD,315 replace a standard 1N5817 in existing designs?
Only with layout revision. While both are 30 V/0.5 A Schottkys, PMEG3005ELD,315 uses SOD882D (1.0 × 0.6 mm) versus DO-213AA (4.5 × 2.7 mm), requiring new footprint, stencil aperture, and thermal pad design. Electrical substitution alone risks solder joint failure and thermal runaway.
