Product details
Overview
PMEG3030EXE from Nexperia is a planar Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 3 A average forward current at 163 °C solder point temperature, 30 V reverse voltage rating, 500 mV typical forward voltage at 3 A/25 °C, and 6 K/W junction-to-solder-point thermal resistance with cathode pad cooling.
For engineers reviewing the PMEG3030EXE datasheet, PMEG3030EXE pinout, PMEG3030EXE application, or PMEG3030EXE equivalent, key selection criteria include its low VF (500 mV @ 3 A), ultra-low IR (15 µA @ 30 V/25 °C), 50 A non-repetitive surge capability, and exposed-cathode thermal design optimized for FR4 PCBs with 1 cm² copper pad.
Technical Context
This Schottky rectifier uses a planar metal–semiconductor junction architecture to achieve fast switching with near-zero reverse recovery charge (Qrr = 2.5 nC) and nanosecond-level trr (5 ns step, 7 ns ramp). Its clip-bond construction and exposed cathode tab enable direct thermal coupling to PCB copper, reducing Rth(j-sp) to 6 K/W - critical for sustained 3 A operation in compact power stages.
The device operates across -55 °C to 175 °C junction temperature range, with VF increasing only marginally at elevated temperatures (550 mV @ 3 A/-40 °C; 445 mV @ 3 A/125 °C), and exhibits stable reverse leakage up to 25 mA at 125 °C - supporting robust performance in thermally constrained industrial and automotive-adjacent applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 30 V reverse voltage rating - defines maximum blocking capability in reverse-biased operation without breakdown. |
| IF(AV) | 3 A average forward current - sustainable DC or pulsed current under δ = 0.5, 20 kHz square wave, Tsp ≤ 163 °C. |
| VF | 500 mV typical forward voltage at IF = 3 A, 25 °C - directly reduces conduction loss in high-current paths. |
| IR | 15 µA typical reverse current at VR = 30 V, 25 °C - minimizes standby power loss in reverse-polarity protection circuits. |
| Rth(j-sp) | 6 K/W junction-to-solder-point thermal resistance - enables efficient heat transfer from die to PCB cathode pad. |
| Qrr | 2.5 nC reverse recovery charge - lowers switching loss and EMI in high-frequency SMPS topologies. |
| IFS M | 50 A non-repetitive peak forward surge current (tp = 8.3 ms) - supports robust inrush and fault-current handling. |
Pinout & Package
Encapsulated in CFP3-HP (SOD123HP) surface-mount plastic package: 2.80 mm × 1.80 mm × 0.90 mm body, with exposed cathode pad for thermal enhancement and standard FR4-compatible footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to exposed metal pad - primary thermal path and negative output terminal in rectification. |
| 2 | Anode (A) | Positive input terminal - accepts incoming current during forward conduction; no thermal function. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 500 mV @ 3 A/25 °C - cuts conduction loss by ~30% vs. comparable 45 V Schottkys, improving efficiency in 5–12 V rails. |
| Exposed cathode thermal pad | 6 K/W Rth(j-sp) with 1 cm² copper - allows 3 A continuous operation on standard FR4 without heatsink or forced air. |
| High surge robustness | 50 A IFSM (8.3 ms half-sine) - withstands repeated inrush events in DC/DC input stages and battery-input systems. |
| Ultra-low reverse leakage | 15 µA @ 30 V/25 °C - ensures <100 µW standby dissipation in reverse-blocking configurations. |
| Fast recovery performance | 5 ns trr (step), 2.5 nC Qrr - suppresses switching node ringing and reduces gate driver stress in synchronous rectifier designs. |
Applications
| Low-Voltage DC/DC Converter | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 5 V or 12 V buck converters operating at 500 kHz–2 MHz. IC Role / Device Role / Timing Role: Uncontrolled Schottky rectifier replacing MOSFET synchronous switch where simplicity and cost outweigh marginal efficiency gain. Use Value: 500 mV VF minimizes conduction loss at 3 A load; 6 K/W thermal path sustains full current without derating on 1-layer PCB. |
Use Scenario: Input protection for USB-C PD adapters, PoE-powered devices, and portable instrumentation. IC Role / Device Role / Timing Role: Series-connected anode-in configuration blocking reverse voltage while passing forward current with minimal drop. Use Value: 15 µA IR prevents battery drain in standby; 30 V VR covers 24 V nominal systems with 20% tolerance margin. |
| High-Efficiency SMPS | Low-Power Consumption System |
|
Use Scenario: Output rectification in isolated flyback or forward converters delivering ≤3 A at ≤12 V. IC Role / Device Role / Timing Role: Primary freewheeling diode in discontinuous conduction mode (DCM) topologies requiring zero-recovery behavior. Use Value: 2.5 nC Qrr eliminates reverse recovery tail, reducing EMI filter size and enabling smaller magnetics. |
Use Scenario: Power path management in IoT sensors, wearables, and energy-harvesting nodes with microamp-level sleep current. IC Role / Device Role / Timing Role: Isolation diode between dual power sources (e.g., battery + harvester) preventing backfeed and cross-discharge. Use Value: Sub-µA leakage at room temperature preserves >99.9% of stored energy over 30-day shelf life. |
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-3EYH03-M3 | Same 30 V/3 A rating but SOD-123 package (Rth(j-a) = 200 K/W); no exposed cathode pad; VF = 520 mV @ 3 A. | Limited to lower ambient temps or forced-air cooling; unsuitable for high-density layouts needing thermal relief. | Choose when board space is constrained but thermal budget allows higher junction rise. |
| ON Semiconductor NSR3030HT1G | SOD-123FL package, VF = 490 mV @ 3 A, but IR = 30 µA @ 30 V/25 °C and Rth(j-sp) not specified. | Higher leakage increases standby loss in always-on systems; thermal performance unverified for sustained 3 A. | Prefer only if legacy footprint compatibility outweighs thermal and leakage requirements. |
Compared with VS-3EYH03-M3 and NSR3030HT1G, PMEG3030EXE uniquely combines clip-bond thermal efficiency (6 K/W), industry-low IR (15 µA), and verified 3 A continuous capability on standard FR4 - making it optimal for thermally dense, low-leakage, high-reliability power rails.

FAQ
What is the maximum continuous forward current for PMEG3030EXE on a standard FR4 PCB?
The PMEG3030EXE supports 3 A average forward current (IF(AV)) when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard footprint - provided the solder point temperature (Tsp) does not exceed 163 °C under δ = 0.5, 20 kHz square-wave conditions. Derating is required above this temperature.
Does PMEG3030EXE have a specified reverse recovery time (trr)?
Yes - PMEG3030EXE specifies trr = 5 ns for step recovery and 7 ns for ramp recovery, measured at IF = 0.5 A, IR = 0.5 A, and Tj = 25 °C. As a Schottky diode, it achieves these values via majority-carrier conduction, eliminating minority-carrier storage delay.
Can PMEG3030EXE be used in automotive applications?
No - PMEG3030EXE is not AEC-Q200 qualified and is explicitly designated as non-automotive in Nexperia's legal disclaimers. It lacks automotive-grade qualification testing, extended temperature validation beyond 175 °C junction, and guaranteed PPAP documentation.
How does the CFP3-HP package improve thermal performance over standard SOD-123?
The CFP3-HP (SOD123HP) package features an exposed cathode pad that serves as the primary thermal interface - achieving Rth(j-sp) = 6 K/W with a 1 cm² copper pad, versus ~200 K/W junction-to-ambient in standard SOD-123. This enables 3× higher power density without heatsinks or airflow.
