Product details
Overview
PMEG3020EPA-QX from Nexperia is a 30 V, 2 A low forward voltage Schottky barrier rectifier in an ultra-thin DFN2020-3 (SOT1061) leadless package, featuring dual anodes and an exposed cathode pad for thermal management. It delivers VF = 410–470 mV at 2 A and 25 °C, IR ≤ 2500 µA at 30 V, and is AEC-Q101 qualified for automotive-grade reliability in low-voltage DC/DC conversion and reverse polarity protection circuits.
For engineers reviewing the PMEG3020EPA-QX datasheet, PMEG3020EPA-QX pinout, PMEG3020EPA-QX application, or PMEG3020EPA-QX equivalent, this device is selected for high-efficiency rectification where low conduction loss, compact footprint, and junction-to-solder-point thermal resistance of 12 K/W are critical design requirements.
Technical Context
This planar Schottky diode integrates a guard ring for mechanical and electrical stress protection and uses a dual-anode configuration to support parallel current paths while maintaining low VF. Its thermal design centers on the exposed cathode pad - the sole thermal interface to the PCB - enabling Rth(j-sp) = 12 K/W when soldered to a 1 cm² copper pad on FR4.
The device operates with zero reverse recovery time (trr < 50 ns), eliminating switching losses in high-frequency SMPS topologies. Its capacitance is 55 pF at 10 V reverse bias, supporting fast transient response in battery charger and USB power path applications without oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 2 A | 410–470 mV - Enables <0.94 W conduction loss per diode in 2 A load paths, reducing heat sink requirements. |
| VR | 30 V - Supports 24 V nominal systems with 25 % headroom for transients in automotive and industrial power rails. |
| IF(AV) | 2 A - Sustains continuous output current in compact DC/DC modules without derating below 65 °C ambient. |
| IR @ 30 V | 435–2500 µA - Low leakage preserves battery standby life in mobile equipment and IoT edge nodes. |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables >1.8 W total power dissipation on ceramic PCBs. |
| trr | 47 ns - Near-zero reverse recovery eliminates snubber networks in 500 kHz–1 MHz buck converters. |
| Cd @ 10 V | 55 pF - Minimizes capacitive loading on high-side switch nodes, preserving gate drive integrity. |
Pinout & Package
Encapsulated in a 2.0 mm × 2.0 mm × 0.65 mm DFN2020-3 (SOT1061) leadless plastic package with exposed cathode thermal pad. The package supports reflow-only soldering and features three terminals: two anodes (A1, A2) and one shared cathode (K).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode 1 | Primary current entry point; electrically identical to A2; used for dual-path layout symmetry or redundancy. |
| 2 (A2) | Anode 2 | Secondary anode terminal; both anodes must be connected to same potential for rated IF(AV) = 2 A operation. |
| 3 (K) | Cathode | Exposed metal pad - sole thermal and electrical return path; requires ≥1 cm² copper pour for full 1.8 W rating. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents edge breakdown under mechanical stress or contamination, extending field lifetime in harsh environments. |
| Dual-anode architecture | Reduces effective series resistance by ~15 % vs. single-anode equivalents, lowering VF at high current density. |
| AEC-Q101 qualification | Validated for automotive underhood use (−40 °C to +150 °C junction), including HTRB, HTGB, and temperature cycling. |
| Ultra-thin profile (0.65 mm max) | Enables stacking in space-constrained portable electronics and multi-layer power modules. |
| Reflow-only assembly | Eliminates wave soldering compatibility concerns and ensures consistent thermal pad wetting during mass production. |
Applications
| Battery Charger for Mobile Equipment | Automotive USB Power Delivery Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR30F30NXT5G | Same 30 V VR, but VF = 450–520 mV @ 2 A; Rth(j-a) = 190 K/W on FR4 (vs. 130 K/W for PMEG3020EPA-QX). | Lacks AEC-Q101 qualification; rated only for commercial temperature range (−40 °C to +125 °C). | Select when cost sensitivity outweighs automotive qualification and thermal performance. |
| Vishay VSKY220HM3/H | Higher VR = 40 V; VF = 490 mV @ 2 A; larger 3.3 mm × 3.3 mm SO-8FL package; Rth(j-sp) not specified. | SO-8FL footprint requires more board area; no dual-anode configuration limits layout flexibility. | Select when system requires 40 V transient margin and board space permits larger package. |
Compared with NSR30F30NXT5G and VSKY220HM3/H, PMEG3020EPA-QX offers superior thermal performance via its optimized DFN2020-3 cathode pad, AEC-Q101 compliance for automotive deployment, and dual-anode symmetry for low-inductance PCB routing - making it optimal for space- and reliability-critical 24 V embedded power stages.

FAQ
Is PMEG3020EPA-QX pin-compatible with standard SOD-123 or SMA packages?
No. PMEG3020EPA-QX uses a 3-terminal DFN2020-3 (SOT1061) leadless package with bottom-side thermal pad and dual anodes - incompatible with through-hole or traditional SMD diode footprints. Its PCB layout requires dedicated 2.0 mm × 2.0 mm land pattern with exposed cathode pad solder stencil.
Can both anodes (A1 and A2) be used independently in split-current paths?
No. The datasheet specifies that both anodes must be connected to the same potential to achieve rated IF(AV) = 2 A. Using them independently violates the internal die construction and may cause uneven current sharing, localized overheating, and premature failure.
What is the maximum allowable solder point temperature during reflow for PMEG3020EPA-QX?
The absolute maximum solder point temperature is not explicitly defined, but the datasheet mandates reflow-only assembly with peak profile ≤ 260 °C (per J-STD-020). Thermal characterization assumes Tsp ≤ 140 °C for full 2 A average current rating - exceeding this risks irreversible junction degradation.
Does PMEG3020EPA-QX require external snubber circuitry in 1 MHz SMPS designs?
No. With trr = 47 ns and zero minority-carrier storage, PMEG3020EPA-QX exhibits negligible reverse recovery ringing. Its 55 pF capacitance at 10 V reverse bias is stable and predictable, allowing direct integration into high-frequency buck converters without snubbers or damping resistors.
