Product details
Overview
PMEG3020ER,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency power conversion. It delivers 2 A average forward current at ≤30 V reverse voltage, features 365–420 mV forward voltage at 2 A/25 °C, and uses clip-bond technology for enhanced thermal performance in SOD123W (CFP3) package. It is deployed in DC-DC converters and reverse polarity protection circuits where low conduction loss and compact footprint are critical.
For engineers reviewing the PMEG3020ER,115 datasheet, PMEG3020ER,115 pinout, PMEG3020ER,115 application, or PMEG3020ER,115 equivalent, this device is selected for its verified low VF stability across temperature, robust 150 °C junction rating, and compatibility with both reflow and wave soldering on FR4 and ceramic PCBs.
Technical Context
This Schottky rectifier employs a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its clip-bond interconnect reduces thermal resistance and enables higher power density versus wire-bonded equivalents.
It operates as a unidirectional, low-loss power diode with negligible minority-carrier storage-enabling zero-recovery switching behavior ideal for high-frequency SMPS topologies. Reverse leakage remains below 1.5 mA at 30 V/25 °C, and capacitance drops from 170 pF at 1 V to 60 pF at 10 V (1 MHz), supporting fast switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A - Sustains continuous forward current up to 2 A with δ = 0.5 square-wave excitation and solder point ≤140 °C. |
| VR | 30 V - Maximum reverse blocking voltage; rated per IEC 60134 absolute maximum system. |
| VF @ 2 A, 25 °C | 365–420 mV - Low conduction loss directly reduces power dissipation and improves efficiency in low-VOUT rails. |
| IR @ 30 V, 25 °C | 0.6–1.5 mA - Controlled leakage ensures minimal standby loss in battery-powered or energy-sensitive systems. |
| Rth(j-sp) | 18 K/W - Thermal resistance from junction to cathode solder point enables effective heat extraction via PCB copper. |
| Cd @ 1 V, 1 MHz | 170 pF - Junction capacitance impacts switching node ringing; value supports <1 MHz operation with low EMI risk. |
| Tj(max) | 150 °C - Maximum junction temperature allows operation in thermally constrained enclosures without derating. |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, optimized for automated assembly and thermal transfer via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side bar) | Cathode (K) | Negative output terminal; connects to PCB thermal pad for heat sinking; marking bar identifies polarity during placement. |
| 2 | Anode (A) | Positive input terminal; carries forward current into the Schottky junction; no internal thermal path beyond lead frame. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses electric field crowding at die edges, improving long-term reliability under repetitive surge or reverse-bias transients. |
| Clip-bond construction | Reduces bond wire inductance and thermal resistance vs. wire-bonded diodes, enabling higher peak current (50 A IFSM) and better thermal response. |
| SOD123W footprint | Standardized 2.6 mm × 1.7 mm land pattern supports high-density layout and compatibility with JEDEC reflow profiles (J-STD-020). |
| Reflow/wave solder compatible | Qualified for both Pb-free reflow (peak 260 °C) and wave soldering, eliminating process-specific qualification overhead. |
| Low VF temperature stability | Forward voltage increases only ~0.2 mV/°C from −40 °C to 125 °C, maintaining predictable loss across industrial ambient ranges. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Used in synchronous or asynchronous buck converter outputs delivering 3.3 V or 5 V at up to 2 A. IC Role / Device Role / Timing Role: Unidirectional freewheeling path during low-side switch off-time; conducts only when output voltage exceeds input rail. Use Value: 365–420 mV VF minimizes conduction loss, increasing efficiency by ≥0.8% over standard 500 mV Schottkys at 2 A load. |
Use Scenario: Placed in series with VIN to block reverse supply connection in portable battery-powered devices. IC Role / Device Role / Timing Role: Forward-conducting series element during correct polarity; open-circuit under reverse bias. Use Value: 1.5 mA max IR at 30 V ensures <15 µW standby loss, preserving battery life in always-on subsystems. |
| Low-Voltage AC Adapter Rectification | USB Power Delivery Input Protection |
|
Use Scenario: Secondary-side rectifier in 12 V/2 A wall adapters feeding 5 V LDOs or USB hubs. IC Role / Device Role / Timing Role: Converts transformer secondary AC to pulsating DC; handles full-load RMS current with minimal heating. Use Value: 2 A IF(AV) rating and 150 °C Tj rating allow sustained operation at 90 °C ambient without derating on standard FR4. |
Use Scenario: In-line protection between USB-C receptacle and PD controller IC to prevent damage from miswired cables. IC Role / Device Role / Timing Role: Standby-blocking element that conducts only during valid VBUS polarity events. Use Value: 30 V VR rating exceeds USB PD 20 V max, while 50 A IFSM withstands hot-plug surge currents without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semi MBRM120L | Same 2 A/30 V rating but VF = 450 mV typ @ 2 A; SOD-123 package (not SOD123W); Rth(j-a) = 250 K/W (vs. 220 K/W). | Lacks guard ring; lower surge robustness; slightly higher conduction loss reduces efficiency in thermally tight layouts. | Select if legacy SOD-123 footprint is fixed and 85 mV VF penalty is acceptable. |
| Vishay VSKY220HM3/H | 2 A/20 V rating; VF = 390 mV typ @ 2 A; SOD-123W package; Tj = 125 °C (vs. 150 °C). | Lower VR limits use to ≤12 V systems; reduced thermal margin restricts high-ambient deployments. | Select only for 12 V or lower systems where 30 V margin is unnecessary and 125 °C Tj suffices. |
Compared with MBRM120L and VSKY220HM3/H, PMEG3020ER,115 offers superior thermal capability (150 °C Tj, 18 K/W Rth(j-sp)), lower VF, and guard-ring-enhanced ruggedness-making it optimal for space-constrained, high-efficiency 24–30 V input designs requiring long-term reliability.

FAQ
What is the maximum allowable solder point temperature during reflow for PMEG3020ER,115?
The device is qualified for standard Pb-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The solder point (cathode tab) must not exceed 140 °C during steady-state operation, as specified in the limiting values table for IF(AV) derating.
Does PMEG3020ER,115 have automotive qualification?
No. Per the 2023 revision history, PMEG3020ER was explicitly changed to non-automotive qualification. It is not AEC-Q101 qualified and lacks automotive-grade testing, traceability, or extended temperature validation beyond −55 °C to +150 °C.
How does the guard ring affect reliability in reverse-biased transient conditions?
The integrated guard ring redistributes electric field lines away from the active junction periphery, preventing premature edge breakdown during repetitive 30 V reverse surges. This extends lifetime in applications exposed to load-dump or inductive kickback events.
Can PMEG3020ER,115 be used in parallel for higher current handling?
Not recommended without external balancing. Schottky VF mismatch causes current hogging; the datasheet provides no parallel-operation guidance. For >2 A, select a single higher-rated device such as PMEG3030ER (3 A) or use active current-sharing circuitry.
