Product details
Overview
PMEG4020ETR from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 40 V reverse voltage and 2 A average forward current at Tsp ≤ 165 °C, featuring low 430–490 mV forward voltage at 2 A/25 °C and operation up to 175 °C junction temperature - deployed in high-efficiency DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4020ETR datasheet, PMEG4020ETR pinout, PMEG4020ETR application, or PMEG4020ETR equivalent, this device is selected for high-temperature rectification where low VF, thermal robustness, and SOD123W footprint compatibility are critical design constraints.
Technical Context
This Schottky diode uses planar construction with an integrated guard ring to enhance surge reliability and reduce leakage under high-temperature bias. Its clip-bonding technology improves thermal transfer and power handling versus wire-bonded equivalents.
The device operates across −55 °C to +175 °C ambient and junction temperatures, with reverse current rising from 25 µA at 25 °C to 15 mA at 125 °C under 40 V bias - requiring careful thermal management in high-duty-cycle applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown in standard operating conditions |
| Avg. Forward Current (IF(AV)) | 2 A - sustainable DC or pulsed rectification with δ = 0.5 on FR4 PCB at Tsp ≤ 165 °C |
| Forward Voltage (VF) | 430–490 mV at IF = 2 A, Tj = 25 °C - enables <1 W conduction loss per diode in 12 V/2 A rail |
| Reverse Current (IR) | 25–100 µA at VR = 40 V, Tj = 25 °C - low leakage preserves efficiency in standby modes |
| Junction Temperature (Tj) | 175 °C - supports operation in engine control units, industrial motor drives, and enclosed power supplies |
| Thermal Resistance (Rth(j-sp)) | 18 K/W - low junction-to-solder-point resistance enables effective heat extraction via cathode tab |
| Diode Capacitance (Cd) | 95 pF at VR = 10 V, f = 1 MHz - minimizes switching noise and EMI in high-frequency SMPS |
Pinout & Package
Encapsulated in a compact SOD123W (CFP3) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, with flat leads optimized for thermal dissipation and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Negative output terminal; marked by bar; connects to heatsink or ground plane for thermal path |
| 2 | Anode (A) | Positive input terminal; carries full forward current; requires trace width ≥ 0.5 mm for 2 A continuous |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge immunity and reduces localized field crowding during transient overvoltage events |
| Clip-bonding construction | Reduces thermal resistance by ~30% vs. wire-bonded SOD123 devices, enabling higher power density |
| SOD123W package | Enables 0.65 mm profile height and 1.1 mm pad spacing - compatible with dense PCB layouts and reflow profiles |
| 175 °C junction rating | Supports operation in under-hood automotive modules and industrial inverters without derating at 125 °C ambient |
| Low 430 mV VF typ. | Reduces conduction loss by ~25% vs. comparable 40 V Schottkys, improving system efficiency in 5–24 V rails |
Applications
| Power Supply Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Output rectification in 12 V/2 A synchronous buck converter operating at 500 kHz. IC Role / Device Role / Timing Role: Low-VF freewheeling diode replacing MOSFET body diode to reduce conduction loss and improve light-load efficiency. Use Value: 430 mV VF limits power loss to 0.86 W at 2 A, reducing thermal stress on adjacent controllers. |
Use Scenario: Input protection for a 24 V industrial sensor node powered from external terminals. IC Role / Device Role / Timing Role: Series-connected Schottky in the positive rail to block reverse connection while minimizing voltage drop. Use Value: 490 mV max VF ensures >23.5 V delivered to load during normal operation, preserving sensor accuracy. |
| High-Temperature Motor Control | Low-Power DC-DC Conversion |
|
Use Scenario: Freewheeling path in a brushed DC motor driver mounted near gearbox housing (Tamb ≈ 110 °C). IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback during PWM turn-off, operating continuously at Tj up to 150 °C. Use Value: 175 °C Tj rating avoids thermal shutdown; 15 mA IR at 125 °C maintains safe blocking margin. |
Use Scenario: Secondary-side rectifier in a 5 V/1 A isolated flyback supplying microcontroller peripherals. IC Role / Device Role / Timing Role: High-frequency rectifier handling 100 kHz switching with minimal capacitive coupling into analog sections. Use Value: 95 pF Cd at 10 V suppresses ringing and EMI, easing EMC compliance without snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EYH04-M3/5BT | Same 40 V/2 A rating but TO-277 package (larger, 3.5 mm × 2.5 mm); VF = 490 mV typ. at 2 A | Requires larger PCB area; better thermal mass but lower power density | Select when board space allows and higher surge IFSM (80 A) is required |
| ON Semiconductor NSR20F40NXT5G | SOD-123FL package (same footprint); VF = 450 mV typ. at 2 A; Tj = 150 °C max | Limited to 150 °C operation; unsuitable for >125 °C ambient environments | Select only for cost-sensitive, non-high-temp applications with identical layout |
Compared with VS-2EYH04-M3/5BT and NSR20F40NXT5G, PMEG4020ETR uniquely combines SOD123W footprint, 175 °C rating, and sub-450 mV VF, making it optimal for thermally constrained, high-reliability industrial power stages.

FAQ
What is the maximum allowable solder point temperature for PMEG4020ETR during reflow?
The datasheet specifies Tsp ≤ 165 °C for continuous operation at IF(AV) = 2 A. During reflow, peak temperature must not exceed 260 °C for ≤ 30 seconds per JEDEC J-STD-020, with the solder point (cathode tab) monitored separately to avoid exceeding 165 °C sustained thermal stress.
Can PMEG4020ETR replace a standard 1N5819 in a 5 V/1 A buck converter?
Yes - with VF of 430–490 mV at 2 A (vs. 1N5819's ~450–600 mV), PMEG4020ETR delivers lower conduction loss and higher temperature capability (175 °C vs. 125 °C). Its SOD123W footprint matches 1N5819's SOD-123, enabling direct layout reuse.
How does the guard ring affect surge performance compared to non-guarded Schottkys?
The integrated guard ring distributes electric field stress away from the active junction edge, increasing non-repetitive peak forward current (IFSM) to 50 A and improving resistance to ESD and line transients - validated per IEC 61000-4-5 surge testing protocols in reference designs.
Is PMEG4020ETR qualified for automotive applications?
No - the datasheet explicitly states "Non-automotive qualified products" in Section 15. It lacks AEC-Q101 qualification, automotive PPAP documentation, and extended temperature validation beyond 175 °C junction. Use only in industrial, consumer, or computing applications unless independently qualified.
