Product details
Overview
PMEG4020ER,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 2 A average forward current, featuring low 430–490 mV forward voltage at 2 A and 25 °C junction temperature, housed in a SOD123W (CFP3) surface-mount package - used in high-efficiency DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4020ER,115 datasheet, PMEG4020ER,115 pinout, PMEG4020ER,115 application, or PMEG4020ER,115 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance to solder point (18 K/W), reverse leakage at 40 V (≤100 µA), and compatibility with FR4 or ceramic PCB layouts per IEC 60134 limiting values.
Technical Context
This Schottky rectifier employs clip-bond technology to achieve high power capability in a compact SOD123W footprint, enabling efficient low-voltage rectification without PN-junction switching losses. Its guard ring structure enhances robustness against electrical overstress during transient conditions.
Thermal performance is defined across three mounting configurations: Rth(j-a) ranges from 70 K/W (ceramic PCB) to 220 K/W (FR4 standard footprint), while Rth(j-sp) is fixed at 18 K/W - critical for predicting junction temperature rise under pulsed or continuous DC loads up to 2 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking voltage before breakdown; defines usable input range in 12 V/24 V SMPS front-ends. |
| Average Forward Current (IF(AV)) | 2 A - sustained DC or square-wave current handling at Tsp ≤ 140 °C; supports compact power stage designs. |
| Forward Voltage (VF) | 430–490 mV @ 2 A, 25 °C - directly reduces conduction loss and improves efficiency in low-VOUT buck converters. |
| Reverse Current (IR) | 25–100 µA @ 40 V, 25 °C - low leakage preserves battery life in always-on reverse-polarity protection paths. |
| Diode Capacitance (Cd) | 95 pF @ 10 V, 1 MHz - limits high-frequency switching noise and EMI in >1 MHz DC-DC topologies. |
| Junction Temperature (Tj) | 150 °C - maximum operating junction temperature; sets thermal derating envelope for ambient and board layout. |
| Non-repetitive Peak Current (IFSM) | 50 A @ 8.3 ms half-sine - withstands inrush and fault currents without bond-wire fusing. |
Pinout & Package
The PMEG4020ER,115 is packaged in a SOD123W (CFP3) plastic surface-mount case measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for reflow soldering on FR4 or ceramic substrates. The cathode is marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Output terminal for forward conduction; connects to load ground or negative rail; thermal path via cathode tab (Rth(j-sp) = 18 K/W). |
| 2 (A) | Anode | Input terminal for forward conduction; connects to input source or switch node; non-thermal pad with standard trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD and transient overvoltage immunity without external snubbers in 24 V automotive accessory rails. |
| Clip-bond construction | Reduces parasitic inductance and improves thermal transfer vs. wire-bonded Schottkys, supporting higher ripple current stability. |
| SOD123W footprint | Enables <10 mm² board area usage - ideal for space-constrained USB-C PD adapters and portable medical sensors. |
| Low VF at high IF | 430 mV typ. @ 2 A enables ≥95% efficiency in 3.3 V/2 A synchronous buck stages when paired with low-RDS(on) MOSFETs. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Output rectification in 1 MHz synchronous buck converter delivering 3.3 V/2 A to FPGA core logic.

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 NSR4020HT1G | Same 40 V/2 A rating but VF = 450–510 mV @ 2 A; Rth(j-a) = 230 K/W on FR4. | Higher conduction loss and worse thermal dissipation limit use in >1 A continuous DC-DC outputs. | Select when cost sensitivity outweighs 20 mV VF penalty and board layout allows larger thermal relief. |
| Vishay SS24HE3/5BT | 40 V/2 A, VF = 470–530 mV @ 2 A; no guard ring; TO-277 package (larger than SOD123W). | Lacks integrated stress protection; requires external TVS for surge-prone inputs; 3.5× larger footprint. | Prefer only where existing TO-277 footprint reuse is mandatory and transient immunity is managed externally. |
Compared with NSR4020HT1G and SS24HE3/5BT, PMEG4020ER,115 delivers lower forward voltage, superior thermal resistance to solder point, and built-in guard ring - making it optimal for space-constrained, high-reliability 12–24 V DC-DC and protection circuits where efficiency and robustness are co-prioritized.

FAQ
What is the maximum allowable solder point temperature for PMEG4020ER,115 during reflow?
The datasheet specifies a maximum solder point temperature of 140 °C for continuous operation (Tsp ≤ 140 °C). During reflow, peak profile must not exceed 260 °C for ≤10 seconds per JEDEC J-STD-020, with thermal resistance to solder point fixed at 18 K/W - ensuring safe junction rise under validated PCB land patterns.
Does PMEG4020ER,115 require a heatsink in 2 A DC operation?
No heatsink is required for 2 A DC operation if mounted on an FR4 PCB with 1 cm² cathode pad (Rth(j-a) = 130 K/W) and ambient ≤55 °C. At 25 °C ambient, junction temperature reaches ~95 °C - well below the 150 °C limit. Thermal simulation using Fig. 9–11 curves confirms safe operation within derated boundaries.
How does the guard ring improve reliability in reverse polarity protection?
The integrated guard ring suppresses edge electric field crowding during reverse-bias transients, raising the effective breakdown voltage margin by ≥15% and preventing localized avalanche damage. This extends operational lifetime in 12 V automotive accessory circuits exposed to load-dump spikes up to 35 V.
Can PMEG4020ER,115 replace a standard silicon diode in a 5 V/1 A linear regulator input?
Yes - its 430 mV VF reduces dropout voltage by 270 mV versus a typical 1N4007 (0.7 V), increasing usable input range and reducing heat generation. However, reverse leakage (25 µA) is higher than silicon (≤5 µA), so verify impact on ultra-low-quiescent LDO bias networks.
