Product details
Overview
PMEG2020EJF 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 typical forward voltage of 450 mV at 2 A (25 °C), housed in an ultra-compact SOD323F (SC-90) surface-mount package. It serves as a low-loss unidirectional power switch in space-constrained DC/DC converters and reverse-polarity protection circuits.
For engineers reviewing the PMEG2020EJF datasheet, PMEG2020EJF pinout, PMEG2020EJF application, or PMEG2020EJF equivalent, key selection criteria include its 450–525 mV VF at 2 A, 20 V VR rating, 50–60 pF junction capacitance at 5 V, thermal resistance of 150 K/W to solder point, and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a planar silicon 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 contact and shallow junction design, enabling operation at junction temperatures up to 150 °C.
The device exhibits temperature-dependent VF and IR characteristics: VF rises slightly with decreasing temperature (e.g., 200 mV at 0.01 A, −40 °C), while IR increases significantly above 85 °C-reaching 200 µA at 20 V and 25 °C, and higher at elevated Tj. Thermal performance is defined for two PCB mounting conditions: standard footprint (350 K/W Rth(j-a)) and enhanced cathode pad (150 K/W Rth(j-sp)).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability before significant leakage or breakdown; defines usable input range in 12 V systems with margin. |
| Forward Current (IF) | 2 A continuous - Sustained conduction capacity at ≤55 °C solder point temperature; supports compact 1–2 W power stages. |
| Forward Voltage (VF) | 450–525 mV @ 2 A - Directly reduces conduction loss (≤1.05 W at 2 A), critical for >90 % efficiency in low-voltage buck converters. |
| Junction Capacitance (Cd) | 50–60 pF @ 5 V - Limits high-frequency switching noise and recovery-related ringing in MHz-range SMPS designs. |
| Reverse Leakage (IR) | 45–200 µA @ 20 V, 25 °C - Low standby loss in battery-powered polarity protection; rises with temperature and voltage. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - With 1 cm² cathode copper pad, enables ~5.5 °C/W rise per watt; allows 2 A operation without active cooling. |
| Package | SOD323F (SC-90) - 1.7 × 1.25 × 0.7 mm body; compatible with 0201-class reflow footprints and automated placement. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) surface-mount plastic package, the PMEG2020EJF features a 2-terminal configuration with gull-wing leads optimized for high-density PCB assembly and thermal dissipation via the cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to system ground or return path; primary thermal interface-requires ≥1 cm² copper for rated current handling. |
| 2 (A) | Anode | Input or source-side connection; carries full forward current; minimal thermal contribution compared to cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge electric field concentration, improving surge robustness and long-term reliability under repetitive transients. |
| Ultra-low VF at 2 A | 450 mV typical enables <1.0 W conduction loss at full load-critical for thermally constrained IoT and wearables. |
| SOD323F footprint | 1.7 × 1.25 mm outline fits 0201 land patterns, reducing board area by >30 % vs. SOD123 or SMA packages. |
| 150 °C max junction temperature | Supports operation in sealed enclosures or near heat sources without derating below 2 A up to Tamb = 85 °C. |
| Low Cd (50–60 pF) | Minimizes capacitive coupling and switching node oscillation in synchronous rectifier and flyback snubber circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G (ON Semiconductor) | 20 V VR, 200 mA IF - lower current rating; VF = 370 mV @ 100 mA; SOD-523 package (1.2 × 0.8 mm). | Not suitable for 2 A loads; used only in sub-100 mA bias or signal-level clamping. | Select only when board space is tighter than 1.2 × 0.8 mm and current ≤100 mA. |
| SS22 (Micro Commercial Components) | 20 V VR, 2 A IF; VF = 500 mV @ 2 A; DO-214AC (SMA) package - 4.5 × 2.7 mm, 3× larger footprint. | Higher thermal mass but requires 3× PCB area; Rth(j-a) ≈ 70 K/W with heatsink. | Choose when higher surge current (IFSM = 50 A) or manual assembly is required; not for miniaturized designs. |
Compared with RB520S-30T1G and SS22, the PMEG2020EJF uniquely balances 2 A capability, 450 mV VF, and 1.7 × 1.25 mm size-enabling high-efficiency rectification where both current and space constraints apply, unlike the micro-current RB520S-30T1G or bulky SS22.

FAQ
What is the maximum allowable solder point temperature for PMEG2020EJF during reflow?
The PMEG2020EJF is qualified for standard lead-free reflow profiles with peak temperature up to 260 °C for ≤30 seconds, per JEDEC J-STD-020. Its SOD323F package uses tin-plated copper leads and is rated for thermal cycling stability over 1000 cycles between −65 °C and +150 °C.
Can PMEG2020EJF be used in automotive applications?
No-per Revision v.6 (October 2024), PMEG2020EJF is explicitly designated as non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation beyond 150 °C junction. Automotive alternatives must be selected from Nexperia's -Q qualified Schottky series.
How does the guard ring affect surge performance?
The integrated guard ring redistributes electric field lines at the die edge, raising the effective breakdown voltage under transient conditions. This improves robustness against repetitive 100 ns/1 A surge pulses and electrostatic discharge events, extending operational life in environments with frequent hot-plug or cable insertion stress.
Is the marking "CA" on the device body sufficient for traceability?
Yes-the "CA" marking corresponds exclusively to the PMEG2020EJ type number per Nexperia's official marking code table. Combined with date code and factory identifier (not visible on top mark), it enables full lot-level traceability through Nexperia's quality database and Aetrix's documented sourcing records.
