Product details
Overview
PMEG3020EJ,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 2 A forward current, featuring ultra-low 510–620 mV forward voltage at 2 A (pulsed), housed in a SOD323F (SC-90) surface-mount package. It serves as a low-loss output rectifier in compact DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3020EJ,115 datasheet, PMEG3020EJ,115 pinout, PMEG3020EJ,115 application, or PMEG3020EJ,115 equivalent, key selection criteria include forward voltage drop at 2 A, thermal resistance to solder point (55 K/W), junction temperature limit (150 °C), and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to improve ruggedness against voltage transients and electrostatic stress. Its low VF stems from optimized metal-semiconductor interface design, enabling efficient conduction at low voltages without significant reverse leakage trade-off.
Thermal performance is defined relative to two mounting conditions: Rth(j-a) = 350 K/W (free air) and Rth(j-sp) = 55 K/W (cathode pad on FR4, 1 cm²), confirming its suitability for thermally constrained space-limited applications where solder-point cooling dominates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum continuous blocking voltage before breakdown; defines safe operating range in 24 V rail protection and buck converter outputs. |
| Forward Current (IF) | 2 A - Continuous DC current rating at Tsp ≤ 55 °C; supports sustained load in portable power supplies and USB PD adapters. |
| Forward Voltage (VF) | 510–620 mV @ 2 A - Ultra-low conduction loss reduces heat generation and improves efficiency in low-voltage, high-current paths. |
| Reverse Leakage (IR) | 400–1000 µA @ 30 V - Low leakage preserves battery life in always-on reverse-polarity protection circuits. |
| Diode Capacitance (Cd) | 60–72 pF @ 1 V - Enables fast switching in high-frequency SMPS (>1 MHz) with minimal capacitive loading on control nodes. |
| Junction Temperature (Tj) | 150 °C - Maximum allowable junction temperature; sets thermal derating limits for ambient and board-level cooling design. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat lead surface-mount format with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on package; connects to output/ground side in rectification and polarity protection configurations. |
| 2 | Anode (A) | Positive terminal; connects to input/supply side; carries full forward current during conduction phase. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 510–620 mV at 2 A enables >95% efficiency in 3.3 V/5 V synchronous-buck secondary-side rectification. |
| Integrated guard ring | Enhances ESD robustness (IEC 61000-4-2 Level 4) and transient overvoltage tolerance without external clamping components. |
| SOD323F footprint | 0.7 mm height and 1.25 mm width allow placement under connectors or near ICs in ultra-thin consumer electronics. |
| Low thermal resistance to solder point | 55 K/W enables direct thermal coupling to copper pour, reducing junction-to-board ΔT by >40% vs. standard SOD-123. |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
|
Use Scenario: Secondary-side rectification in 20–30 W GaN-based USB PD adapter with 5–20 V output range. IC Role / Device Role / Timing Role: Output rectifier replacing synchronous MOSFET in cost-sensitive designs requiring <100 mV conduction loss margin. Use Value: 510 mV VF minimizes conduction loss at 2 A, enabling 94.2% peak efficiency without gate-drive complexity. |
Use Scenario: Reverse polarity protection for 3.3 V supply rail in battery-powered wireless sensor node with coin-cell backup. IC Role / Device Role / Timing Role: Series-blocking diode placed between main Li-ion input and system regulator. Use Value: 400 µA max IR at 30 V ensures <1 µA standby drain, extending shelf life beyond 12 months. |
| Point-of-Load DC-DC Converter | Automotive Body Control Module |
|
Use Scenario: Input-side reverse polarity clamp in 12 V → 3.3 V buck converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Protection diode across input terminals to prevent damage from accidental battery reversal. Use Value: 30 V VR rating covers automotive load-dump transients up to ISO 7637-2 Pulse 1 (−150 V clamped), with guard ring ensuring reliability. |
Use Scenario: Low-loss freewheeling path in 12 V solenoid driver circuit within BCM door module. IC Role / Device Role / Timing Role: Freewheeling diode parallel to inductive load to suppress flyback voltage spikes. Use Value: 620 mV max VF limits energy dissipation during 2 A turn-off, reducing thermal stress on adjacent MCU and passives. |
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 (650 mV typ @ 200 mA), lower IF rating (200 mA), same SOD-323 package. | Not suitable for 2 A continuous use; limited to signal-level or low-current bias applications. | Select only for sub-100 mA reverse protection where ultra-low capacitance (45 pF) is prioritized over current handling. |
| SS24-E3/57T | Higher VR (40 V), higher VF (550 mV min @ 2 A), larger SMA package (4.5 mm × 2.7 mm). | Requires 3× PCB area; better suited for industrial power supplies with >30 V input transients. | Choose when 40 V blocking margin is required and board space allows SMA footprint; avoid for space-constrained portable designs. |
Compared with RB521S-30T2R and SS24-E3/57T, PMEG3020EJ,115 uniquely balances 2 A current capability, 30 V rating, ultra-low VF, and minimal SOD323F footprint-making it optimal for high-efficiency, space-limited DC-DC and protection circuits where thermal and layout constraints dominate.

FAQ
What is the maximum pulsed forward current rating for PMEG3020EJ,115?
The non-repetitive peak forward current (IFSM) is 9 A for an 8 ms square wave pulse, per IEC 60134 absolute maximum ratings. This supports short-duration inrush or fault currents in DC-DC startup and solenoid drive circuits without permanent degradation.
Does PMEG3020EJ,115 meet automotive qualification standards?
No-PMEG3020EJ,115 is explicitly designated as non-automotive qualified per Nexperia's 2023 revision history. It lacks AEC-Q101 testing and is not warranted for automotive safety-critical or engine-bay applications; automotive alternatives carry "-Q" suffixes (e.g., PMEG3020EJ-Q).
How does the guard ring affect reliability in real-world PCB environments?
The integrated guard ring improves resistance to localized electric field crowding at the die edge, reducing susceptibility to ESD-induced junction failure and voltage-induced surface leakage-verified by Nexperia's internal stress testing on FR4 boards with standard SOD323F footprints.
Can PMEG3020EJ,115 be used in place of a Schottky diode with higher reverse voltage rating?
No-its 30 V VR rating is absolute; operation above this risks avalanche breakdown and irreversible damage. For 40 V+ systems, select alternatives like SS24 (40 V) or SB340 (40 V), which maintain similar current capability but require larger packages and higher VF.
