Product details
Overview
PMEG3002AELD from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for ultra-compact DC/DC converter output stages and reverse polarity protection circuits. It delivers 0.2 A average forward current at ≤480 mV forward voltage (IF = 200 mA), supports 30 V reverse voltage, and operates with junction temperatures up to 150 °C in SOD882D (DFN1006D-2) package.
For engineers reviewing the PMEG3002AELD datasheet, PMEG3002AELD pinout, PMEG3002AELD application, or PMEG3002AELD equivalent, key selection criteria include low VF performance under pulsed 200 mA loads, side-wettable flanks for solder joint inspection, thermal resistance to solder point (50 K/W), and compatibility with FR4 PCB layouts using 1 cm² cathode pad.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low 430–480 mV VF at 200 mA enables high-efficiency rectification in space-constrained power rails.
The device exhibits ultra-fast switching with trr < 6 ns and low 18–25 pF capacitance at 1 V reverse bias, making it suitable for high-frequency SMPS topologies operating above 1 MHz. Thermal design leverages side pads for enhanced heat conduction to PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - defines maximum blocking capability in reverse-biased protection or freewheeling paths |
| Average Forward Current (IF(AV)) | 0.2 A at δ = 0.5, 20 kHz square wave - usable continuous DC-equivalent current on standard FR4 PCB |
| Forward Voltage (VF) | 430–480 mV at IF = 200 mA, tp ≤ 300 µs - directly reduces conduction loss in high-efficiency buck converters |
| Reverse Current (IR) | 3.5–10 µA at VR = 10 V, 25 °C - ensures minimal leakage in battery-powered reverse polarity guards |
| Diode Capacitance (Cd) | 18–25 pF at VR = 1 V, 1 MHz - limits high-frequency switching noise and EMI in fast-switching nodes |
| Reverse Recovery Time (trr) | < 6 ns - eliminates recovery tail losses in MHz-range synchronous rectifier replacements |
| Thermal Resistance (Rth(j-sp)) | 50 K/W - enables direct thermal path from junction to cathode solder point on PCB |
Pinout & Package
Encapsulated in SOD882D (DFN1006D-2): leadless 1.0 mm × 0.6 mm × 0.37 mm body with side-wettable flanks, 0.65 mm pitch, visible cathode marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; marked with bar; solderable side pad provides thermal and electrical path to PCB ground plane |
| 2 (A) | Anode | Current entry terminal; second solderable side pad enables symmetric layout and thermal symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge breakdown under voltage transients, improving long-term reliability in unregulated input rails |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillets without X-ray, reducing manufacturing defect escape |
| Low-profile 0.37 mm height | Permits stacking under shields or integration into ultra-thin portable electronics (< 3 mm total thickness) |
| Reflow-compatible only | Eliminates risk of thermal damage during hand-soldering; mandates controlled reflow profile per J-STD-020 |
| 1 cm² cathode pad thermal enhancement | Reduces Rth(j-a) to 125 K/W on ceramic PCB - enables 0.2 A operation at 100 °C ambient without derating |
Applications
| USB Power Delivery Input Protection | Wearable Device Battery Charging Path |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Higher VF (500 mV @ 200 mA); same 30 V VR; SOD-523 package (1.2 × 0.8 mm) | Less suitable for <4.5 V input rails due to higher conduction loss; larger footprint reduces density | Select when legacy SOD-523 footprint compatibility is required over VF optimization |
| NSR0230P2T5G | Lower IR (1 µA @ 10 V); same VF range; SOD-923 package (1.0 × 0.6 mm) but no side-wettable flanks | Lacks AOI-capable solder joints; requires X-ray for process validation in high-reliability production | Select when ultra-low leakage dominates over manufacturability requirements |
Compared with RB521S-30T2R and NSR0230P2T5G, PMEG3002AELD uniquely balances lowest VF, side-wettable flanks for inspection, and smallest standardized footprint - making it optimal for high-volume, space-constrained, and automated-optical-inspection-driven designs.

FAQ
What is the maximum allowable soldering temperature profile for PMEG3002AELD?
PMEG3002AELD is qualified for reflow soldering only, per J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp rates limited to 3 °C/s max. Hand soldering is not recommended due to thermal stress risk on the ultra-thin DFN1006D-2 body and internal wire bonds.
Can PMEG3002AELD replace a standard silicon diode in a 5 V SMPS output stage?
Yes - its 430–480 mV VF at 200 mA reduces conduction loss by ~65% versus a typical 1N4148 (VF ≈ 1.2 V). However, ensure reverse voltage does not exceed 30 V and verify layout accommodates side-wettable flanks for reliable solder joint formation.
Is PMEG3002AELD suitable for automotive applications?
No - this part is explicitly non-automotive qualified per Nexperia's revision history (v.2, Oct 2024). It lacks AEC-Q200 qualification and automotive-grade screening. For automotive use, select Nexperia's PMEG3002AELD-Q series or equivalent qualified Schottky rectifiers.
How does the guard ring affect surge robustness in reverse polarity events?
The integrated guard ring redistributes electric field at the die edge, raising the effective breakdown voltage margin by ≥20% under transient conditions. This prevents localized avalanche and metallization lift-off during 100 ms reverse-bias surges up to 30 V, extending lifetime in unregulated input environments.
