Product details
Overview
PMEG4002ELD from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage DC-to-DC conversion and reverse polarity protection in space-constrained power rails. It delivers 40 V reverse voltage rating, 0.2 A average forward current, 540–600 mV forward voltage at 200 mA, <4 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PMEG4002ELD datasheet, PMEG4002ELD pinout, PMEG4002ELD application, or PMEG4002ELD equivalent, this device is selected for ultra-small SMD power management where low VF, high-speed switching, and thermal robustness on FR4 PCBs are critical - especially in battery-powered and automotive subsystems.
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 under transient stress. Its low junction capacitance (14–20 pF at 1 V) and sub-4 ns trr enable operation in high-frequency SMPS topologies up to 20 kHz with minimal switching loss.
The SOD882D package features solderable side pads and a 1.0 × 0.6 × 0.37 mm body height, enabling direct thermal conduction from cathode pad to PCB copper. Thermal resistance from junction to ambient is 190 K/W on FR4 with 1 cm² cathode pad - critical for maintaining Tj ≤ 150 °C under 0.2 A continuous load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports input rails up to 36 V nominal in automotive and industrial DC systems without avalanche risk. |
| Average Forward Current (IF(AV)) | 0.2 A - rated for continuous conduction at Tamb ≤ 120 °C on standard FR4, enabling compact 5–12 V buck converter outputs. |
| Forward Voltage (VF) | 540–600 mV @ 200 mA - reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency in low-VOUT regulators. |
| Reverse Recovery Time (trr) | <4 ns - eliminates minority-carrier tail current, enabling clean zero-voltage switching in synchronous rectifier and flyback designs. |
| Reverse Current (IR) | 0.3–0.5 µA @ 25 V - ensures negligible leakage in battery backup and always-on circuits over temperature. |
| Diode Capacitance (Cd) | 14–20 pF @ 1 V, 1 MHz - minimizes capacitive coupling noise and EMI in high-dv/dt switching nodes. |
| Thermal Resistance (Rth(j-a)) | 190 K/W (FR4, 1 cm² cathode pad) - allows stable operation at 0.2 A without heatsinking in thermally isolated layouts. |
Pinout & Package
Encapsulated in the ultra-small, leadless SOD882D package (1.0 × 0.6 × 0.37 mm), PMEG4002ELD features visible and solderable side pads for automated reflow assembly. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to output rail or ground return path; primary thermal interface - requires ≥1 cm² copper pour for rated current handling. |
| 2 | Anode | Connected to input or switching node; electrically isolated from cathode pad; no thermal function beyond conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge-related avalanche failure during voltage transients, enabling reliable operation in noisy automotive environments. |
| AEC-Q101 qualification | Validated for automotive applications including engine control modules, infotainment power supplies, and ADAS sensor rails. |
| Solderable side pads | Enable full IPC-compliant reflow soldering with optical inspection capability - no hidden joints or voiding risks. |
| Ultra-low profile (0.37 mm typ.) | Permits placement under connectors or beneath shields in ultra-thin portable and telematics modules. |
| Low VF across temperature | VF remains ≤600 mV from −40 °C to +125 °C, ensuring stable efficiency in wide-temperature industrial deployments. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Clamp |

FAQ
What is the maximum allowable peak forward current for PMEG4002ELD?
The non-repetitive peak forward current (IFSM) is 3 A for an 8 ms square wave per IEC 60134, verified under Tj = 25 °C prior to surge. This enables robust handling of inrush currents in DC-DC input stages and hot-swap circuits without derating.
Can PMEG4002ELD be used in reflow-only assembly processes?
Yes - reflow soldering is the only recommended process per Nexperia's documentation. The SOD882D package is qualified for standard lead-free reflow profiles (peak 260 °C), and its side pads ensure reliable joint formation without wave soldering or hand-soldering requirements.
How does the guard ring affect layout requirements?
The integrated guard ring requires no special layout but mandates adherence to the specified cathode pad size (1 cm² minimum on FR4). Reducing pad area increases electric field stress at the die edge, risking premature breakdown - especially under humidity or contamination.
Is thermal resistance affected by PCB material choice?
Yes - Rth(j-a) drops from 190 K/W (FR4, 1 cm² pad) to 125 K/W on Al₂O₃ ceramic PCBs due to higher thermal conductivity. This allows 0.2 A operation at higher ambient temperatures or enables tighter spacing in thermally dense modules.
