Product details
Overview
PMEG3020EH,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, housed in a compact SOD123F surface-mount package. It serves as a low-loss freewheeling or output rectifier in space-constrained DC-DC converters and power supplies.
For engineers reviewing the PMEG3020EH,115 datasheet, PMEG3020EH,115 pinout, PMEG3020EH,115 application, or PMEG3020EH,115 equivalent, key selection criteria include forward voltage drop at 2 A, thermal resistance to solder point (60 K/W), reverse leakage at 30 V (≤1000 µA), and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient voltage stress. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design, enabling efficient conduction at low voltages without significant reverse recovery charge.
The device operates up to 150 °C junction temperature and exhibits low capacitance (60–72 pF at 1 V) and low thermal resistance to solder point (60 K/W), making it suitable for high-frequency switching topologies where switching loss and thermal management are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability before breakdown; sets upper limit for input/output rail voltage in buck or flyback designs. |
| Forward Current (IF) | 2 A continuous - Sustained conduction rating at ≤55 °C solder point temperature; defines usable current range in steady-state power paths. |
| Forward Voltage (VF) | 510–620 mV at 2 A - Directly determines conduction loss (P = IF × VF); enables >95% efficiency in 3.3 V/5 V DC-DC outputs. |
| Reverse Leakage (IR) | 400–1000 µA at 30 V - Impacts standby power in reverse polarity protection; low enough for battery-powered systems. |
| Diode Capacitance (Cd) | 60–72 pF at 1 V - Limits high-frequency switching noise and EMI; supports clean turn-off in MHz-range converters. |
| Thermal Resistance (Rth(j-sp)) | 60 K/W - Enables direct thermal coupling to PCB copper; allows 2 A operation with minimal heatsinking on standard FR4. |
Pinout & Package
Encapsulated in a 2.6 mm × 1.6 mm × 1.1 mm SOD123F plastic surface-mount package with flat leads and cathode-marked body (bar marking on top surface).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on package top; connects to output or ground side in rectification path. |
| 2 | Anode (A) | Positive terminal; connects to input or switch node; carries full forward current during conduction phase. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 510–620 mV @ 2 A reduces conduction loss by ≥30% vs. standard Schottkys, directly improving light-load efficiency. |
| Integrated guard ring | Suppresses edge-related avalanche and improves surge robustness (IFSM = 9 A), enhancing reliability in unregulated input conditions. |
| SOD123F footprint | 2.6 mm × 1.6 mm body with 1.1 mm height enables high-density layout; compatible with standard reflow profiles per IPC-J-STD-020. |
| Low Rth(j-sp) | 60 K/W to solder point allows thermal dissipation through PCB copper alone-no thermal vias required for 2 A operation. |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
|
Use Scenario: Output rectification in 5 V/3 A synchronous buck converter feeding USB-C PD sink circuitry. IC Role / Device Role / Timing Role: Low-VF freewheeling diode replacing MOSFET body diode during dead-time; minimizes voltage drop and heat generation. Use Value: 510 mV VF at 2 A cuts conduction loss to <1.1 W, eliminating need for active cooling in sealed adapter housing. |
Use Scenario: Reverse polarity protection for 3.3 V supply rail powering ultra-low-power MCU and analog sensor front-end. IC Role / Device Role / Timing Role: Series-connected Schottky diode blocking reverse input connection; conducts only during correct polarity. Use Value: 400 µA max IR at 30 V ensures <1.3 µW standby loss-critical for multi-year battery life in wireless sensors. |
| Point-of-Load DC-DC Module | Automotive Body Control Unit (Non-Automotive Qualified) |
|
Use Scenario: Secondary-side rectification in 12 V-to-1.2 V step-down module for FPGA core voltage regulation. IC Role / Device Role / Timing Role: High-frequency synchronous rectifier alternative in cost-sensitive designs where gate drive complexity must be avoided. Use Value: 72 pF Cd limits ringing and EMI at 2 MHz switching, simplifying input filter design and passing CISPR-32 Class B. |
Use Scenario: Input protection diode in 12 V auxiliary supply for non-safety-critical lighting control board. IC Role / Device Role / Timing Role: Polarity guard on main power entry; clamps reverse transients and blocks miswiring. Use Value: 150 °C Tj rating supports operation in engine bay-adjacent enclosures up to 85 °C ambient with derated current. |
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 NSS30201MZ4T1G | Same SOD123F package; VF = 540–650 mV @ 2 A; IR = 500 µA @ 30 V; Rth(j-sp) = 65 K/W. | Slightly higher VF increases conduction loss by ~50 mW at 2 A; identical thermal profile allows drop-in replacement in thermally constrained layouts. | Select when ON Semi supply chain alignment is required; verify layout clearance for 0.25 mm taller body. |
| Vishay SS23-M3/84A | SOD-123 package (not SOD123F); VF = 450–550 mV @ 2 A; VR = 30 V; Rth(j-a) = 330 K/W; no guard ring. | Lower VF improves efficiency but lacks integrated guard ring; higher Rth(j-a) demands more PCB copper area for thermal management. | Prefer for ultra-low-loss priority in open-board designs; avoid in high-transient environments without external clamping. |
Compared with NSS30201MZ4T1G and SS23-M3/84A, PMEG3020EH,115 delivers best-in-class thermal coupling (60 K/W Rth(j-sp)) and proven edge ruggedness via guard ring-critical for industrial power supplies subject to line surges and thermal cycling.

FAQ
What is the maximum allowable solder point temperature for PMEG3020EH,115 during reflow?
The device is qualified for standard lead-free reflow per IPC-J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The solder point temperature limit is defined by its 150 °C maximum junction temperature and 60 K/W thermal resistance; sustained solder point temperatures above 125 °C require current derating per Figure 1 in the datasheet.
Can PMEG3020EH,115 replace a standard PN-junction diode in a 5 V buck converter?
Yes-it replaces standard PN diodes like 1N5819 in output rectification roles. With 510–620 mV VF versus ~700 mV for typical PN diodes, it reduces conduction loss by ~30%, improves efficiency, and eliminates reverse recovery losses-enabling higher switching frequencies without added EMI.
Is PMEG3020EH,115 suitable for automotive applications?
No. Per Nexperia's revision history (v.5, July 2023), this part is explicitly non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, select the PMEG3020EH-Q variant or equivalent AEC-Q101 Schottky diodes.
How does the integrated guard ring affect surge performance?
The guard ring mitigates electric field crowding at the die edge, raising the effective avalanche threshold and enabling repetitive 9 A non-repetitive peak forward current (IFSM) and robust response to ISO 7637-2 pulse 1/2a transients-key for industrial power inputs exposed to load dump or inductive switching noise.
