Product details
Overview
PMEG3020EP,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 average forward current, featuring low 310–360 mV forward voltage at 2 A and housed in a SOD128 (CFP5) surface-mount package. It serves as a high-efficiency, low-loss output rectifier in DC-DC converters and SMPS secondary-side applications.
For engineers reviewing the PMEG3020EP,115 datasheet, PMEG3020EP,115 pinout, PMEG3020EP,115 application, or PMEG3020EP,115 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance under FR4 mounting, reverse leakage at 30 V, junction temperature limit of 150 °C, and compatibility with reflow/wave soldering processes.
Technical Context
This Schottky diode employs clip-bond technology to enhance power capability and thermal performance, enabling stable operation up to 150 °C junction temperature. Its guard ring structure improves robustness against electrical overstress and transient voltage spikes during switching transitions.
The device exhibits low capacitance (325 pF at 1 V, 110 pF at 10 V) and low reverse leakage (1–3 mA at VR = 30 V), supporting high-frequency rectification in compact power supplies. Thermal resistance to ambient ranges from 60 K/W (ceramic PCB) to 200 K/W (standard FR4), directly impacting derating in space-constrained layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V - Maximum blocking voltage before breakdown; sets usable input/output voltage range in buck or flyback topologies. |
| IF(AV) (Avg. Forward Current) | 2 A - Continuous DC or pulsed average current handling at Tsp ≤ 140 °C; defines maximum sustained output current capability. |
| VF (Forward Voltage) | 310–360 mV @ 2 A, 25 °C - Low conduction loss enabling >95% efficiency in low-voltage DC-DC stages. |
| IR (Reverse Current) | 1–3 mA @ 30 V, 25 °C - Low leakage preserves efficiency in standby and light-load conditions. |
| Rth(j-a) (Thermal Resistance) | 200 K/W (FR4, standard footprint) - Determines required PCB copper area and airflow for thermal management. |
| Cd (Diode Capacitance) | 325 pF @ 1 V, 1 MHz - Limits high-frequency switching noise and EMI in fast-switching converters. |
| Tj (Junction Temperature) | 150 °C - Maximum allowable operating junction temperature; constrains power dissipation and layout design. |
Pinout & Package
The PMEG3020EP,115 is housed in a SOD128 (CFP5) plastic surface-mount package measuring 3.8 mm × 2.6 mm × 1.0 mm with 4 mm lead pitch and flat leads optimized for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marked by bar on package; connects to ground or return path in rectifier configuration. |
| 2 | Anode (A) | Positive input terminal; connects to switched node or transformer secondary in SMPS applications. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge immunity without external protection components, improving system-level reliability. |
| Clip-bond construction | Reduces thermal resistance and increases current-carrying capacity versus wire-bonded equivalents. |
| SOD128 package | Enables high-density PCB layouts and supports both reflow and wave soldering without lead damage. |
| Low VF at high IF | 310 mV typical at 2 A enables <100 mW conduction loss per diode-critical for thermally constrained 3.3 V/5 V rails. |
Applications
| Low-Voltage DC-DC Conversion | Switch Mode Power Supply (SMPS) |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 5 V or 3.3 V buck converters for FPGA, microcontroller, or ASIC core supplies. IC Role / Device Role / Timing Role: Output rectifier replacing MOSFETs in low-current designs where gate drive complexity is undesirable. Use Value: Delivers 310 mV VF at 2 A, reducing conduction loss by ~40% versus standard silicon diodes and simplifying thermal design. |
Use Scenario: Output rectification in isolated flyback or forward converters powering industrial I/O modules. IC Role / Device Role / Timing Role: Unidirectional current path on transformer secondary, clamping reverse voltage during switch-off. Use Value: Guard ring ensures robustness against voltage transients induced by transformer leakage inductance. |
| Reverse Polarity Protection | Low-Power Consumption Devices |
Use Scenario: Input protection in battery-powered sensors or USB-C peripheral circuits. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-load; blocks reverse current flow during incorrect battery insertion. Use Value: 1–3 mA IR at 30 V minimizes quiescent current drain, extending battery life in always-on monitoring nodes. |
Use Scenario: Rectification in energy-harvesting circuits (e.g., solar cell or piezoelectric inputs) feeding supercapacitors. IC Role / Device Role / Timing Role: Low-loss AC-to-DC conversion for microwatt-level harvested power. Use Value: 325 pF capacitance at 1 V enables efficient operation even at sub-10 kHz input frequencies common in ambient energy sources. |
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 NSS30201MX | Same 30 V/2 A rating but VF = 370 mV typ. @ 2 A; higher Rth(j-a) = 230 K/W on FR4. | Marginally lower efficiency in high-duty-cycle DC-DC; less suitable for thermally dense layouts. | Select when legacy ON Semi BOM alignment is required and 60 mV VF penalty is acceptable. |
| Vishay VS-3EYH03-M3 | 30 V/2 A, VF = 420 mV typ. @ 2 A; no guard ring; TO-277 package (larger footprint). | Higher conduction loss and larger board area; lacks integrated stress protection for harsh environments. | Prefer only if TO-277 mechanical fit is mandatory and thermal margin exceeds 25 °C. |
Compared with NSS30201MX and VS-3EYH03-M3, PMEG3020EP,115 delivers the lowest VF and includes guard ring protection in the smallest SMD footprint-making it optimal for space- and efficiency-critical 3.3 V/5 V power rails.

FAQ
What is the maximum junction temperature for PMEG3020EP,115?
The absolute maximum junction temperature is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent degradation. Derating curves in Figures 9–11 show how average forward current must be reduced as ambient or solder point temperature rises-e.g., to 1.2 A at Tamb = 100 °C on standard FR4.
Is PMEG3020EP,115 suitable for automotive applications?
No. Per Nexperia's revision history (v.3, Jan 2023), this part is explicitly non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, consult Nexperia's PMEG3020EP-Q series or equivalent qualified alternatives.
How does the guard ring improve reliability?
The integrated guard ring mitigates edge breakdown under high electric field stress, increasing resistance to ESD events (IEC 61000-4-2) and voltage transients caused by parasitic inductance in switching nodes. This extends operational lifetime in noisy industrial or portable power systems without adding external TVS components.
What is the recommended soldering profile for PMEG3020EP,115?
Nexperia specifies compatibility with both reflow and wave soldering. Reflow requires peak temperature ≤ 260 °C (per J-STD-020), with solder land dimensions per Figure 15 (4.4 mm × 2.1 mm). Wave soldering uses the footprint in Figure 16, with preheat ≤ 150 °C and contact time ≤ 5 s to avoid thermal damage to the clip-bond structure.
