Product details
Overview
PMEG2020EJ,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 2 A forward current, featuring a typ. 450 mV forward voltage at 2 A (25 °C), housed in an ultra-compact SOD323F (SC-90) surface-mount package. It serves as a low-loss freewheeling or polarity protection diode in space-constrained DC/DC converters and battery-powered systems.
For engineers reviewing the PMEG2020EJ,115 datasheet, PMEG2020EJ,115 pinout, PMEG2020EJ,115 application, or PMEG2020EJ,115 equivalent, key selection criteria include its 450–525 mV VF at 2 A, 20 V VR rating, 50–60 pF capacitance at 5 V, thermal resistance of 150 K/W (junction-to-solder point), and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low forward voltage stems from optimized metal-semiconductor interface design, enabling reduced conduction loss in low-voltage (<5 V) power rails.
The device operates up to 150 °C junction temperature and exhibits low reverse leakage (≤200 µA at 20 V, 25 °C) and minimal junction capacitance (60 pF max at 5 V), making it suitable for high-frequency switching topologies where switching loss and EMI sensitivity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability without avalanche breakdown; sets upper limit for input/output rail separation in buck or flyback designs. |
| Forward Current (IF) | 2 A continuous - Sustained conduction capacity at ≤55 °C solder point temperature; defines usable current range in compact power stages. |
| Forward Voltage (VF) | 450–525 mV at 2 A - Directly reduces I²R loss and heat generation; enables >95% efficiency in 3.3 V or 5 V synchronous rectifier replacements. |
| Reverse Leakage (IR) | 45–200 µA at 20 V - Low standby power drain critical for battery-backed circuits and always-on subsystems. |
| Junction Capacitance (Cd) | 50–60 pF at 5 V - Limits high-frequency displacement current and ringing; supports clean turn-off in >1 MHz DC/DC controllers. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Quantifies temperature rise from junction to cathode solder point on 1 cm² copper pad; informs thermal relief layout requirements. |
| Package | SOD323F (SC-90) - 1.7 × 1.25 × 0.7 mm body; enables <1.5 mm² board area usage in wearables and IoT sensors. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) surface-mount plastic package: 2-pin, flat lead, 1.7 mm × 1.25 mm × 0.7 mm body height, with standard reflow-compatible footprint per Nexperia drawing sod323f_fr.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward bias; primary thermal path to PCB via cathode pad; must be routed to largest available copper pour. |
| 2 (A) | Anode | Connected to lower-potential node during conduction; carries full load current; requires controlled impedance trace in high-dI/dt paths. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge electric field concentration, improving long-term reliability under repetitive surge stress (e.g., load dump or hot-swap events). |
| Very low VF (450 mV typ.) | Reduces forward conduction loss by ≥30% vs. comparable 20 V Schottkys, directly lowering thermal load in sealed enclosures. |
| SOD323F package | Enables placement within 0.3 mm of adjacent components; compatible with 0201-class pick-and-place equipment and automated optical inspection. |
| 150 °C max junction temperature | Supports operation in thermally aggressive environments (e.g., enclosed industrial controllers) without derating below 2 A up to Tsp = 55 °C. |
Applications
| Battery-Powered IoT Sensor Node | USB-C Power Delivery Clamp |
|---|---|
|
Use Scenario: Reverse polarity protection on 3.3 V supply rail of BLE-enabled environmental sensor with coin-cell backup. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during incorrect battery insertion; no control logic or timing function. Use Value: 450 mV VF adds <0.9 mW loss at 2 mA standby, preserving >10-year battery life; SOD323F footprint fits sub-5 mm² PCB area budget. |
Use Scenario: Input-side reverse voltage clamp in 20 V USB-C PD sink circuit protecting downstream buck controller. IC Role / Device Role / Timing Role: Standby-blocking element clamping fault transients; responds instantaneously with zero recovery time. Use Value: 20 V VR rating matches USB-C PD 20 V profile; 60 pF capacitance avoids signal integrity degradation on CC lines. |
| High-Frequency Buck Converter Output | Low-Voltage FPGA Core Rail Protection |
|
Use Scenario: Freewheeling diode in 2 MHz, 1.2 V/3 A buck converter powering RF transceiver IC. IC Role / Device Role / Timing Role: Synchronous rectification assist; conducts during low-side switch off-time; zero reverse recovery. Use Value: 50 pF Cd minimizes switching node ringing; 150 K/W Rth(j-sp) allows direct thermal coupling to ground plane for stable 1.2 V regulation. |
Use Scenario: Inrush and reverse-bias protection on 0.85 V core supply of Xilinx Artix-7 FPGA during hot-plug configuration. IC Role / Device Role / Timing Role: Passive isolation device; no enable/disable control; blocks backfeed from configuration flash or auxiliary rails. Use Value: 200 µA IR at 20 V ensures <170 nW leakage into 0.85 V rail; SOD323F placement avoids interference with BGA escape routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (550 mV min at 2 A), same 20 V VR, larger SOD-123 package (2.7 × 1.6 mm). | Less suitable for ultra-thin or high-density layouts; higher conduction loss increases thermal burden in sealed modules. | Select when legacy footprint compatibility or higher surge current (IFSM = 12 A) is prioritized over size and efficiency. |
| SS22 | Lower IF rating (2 A avg, but 110 °C derated), VF = 500 mV typ., same SOD-323 package but no guard ring. | Reduced robustness under repeated dv/dt stress; not recommended for automotive-adjacent industrial hot-swap interfaces. | Select only for cost-sensitive consumer applications where transient immunity is not specified. |
Compared with RB050M-30 and SS22, PMEG2020EJ,115 delivers superior thermal performance per unit area (150 K/W vs. ≥200 K/W), tighter VF distribution (±75 mV vs. ±100 mV), and proven guard ring reliability-making it optimal for next-gen miniaturized power management where efficiency, size, and stress resilience are co-constrained.

FAQ
What is the maximum allowable solder point temperature for PMEG2020EJ,115 during reflow?
The device is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The solder point (cathode pad) must remain ≤260 °C; thermal profiling must ensure the 1.7 mm × 1.25 mm SOD323F body does not exceed 245 °C average during heating. Nexperia's recommended footprint (sod323f_fr) provides adequate thermal mass control.
Can PMEG2020EJ,115 replace a standard silicon diode in a 5 V buck converter output stage?
Yes-it replaces 1N5819-class silicon diodes with measurable benefit: at 2 A, VF drops from ~550 mV (silicon) to 450 mV (Schottky), reducing conduction loss by 200 mW and junction temperature rise by ~30 °C on identical PCB copper. No control changes are needed; zero reverse recovery eliminates switching spikes.
Is PMEG2020EJ,115 suitable for automotive applications?
No. Per Nexperia's revision history (v.6, 20241008), this part is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select the PMEG2020EJ-Q variant or equivalent automotive-qualified Schottky rectifiers with documented PPAP support.
How does the integrated guard ring affect layout or reliability in high-dv/dt circuits?
The guard ring mitigates edge breakdown during fast transients (e.g., >100 V/µs), allowing safe operation without external snubbers in hot-swap or load-dump scenarios. Layout requires no special rules beyond standard SOD323F practices-but cathode pad must maintain ≥1 cm² copper area to realize the 150 K/W Rth(j-sp) rating and prevent localized thermal runaway.
