Product details
Overview
PMEG3030EP 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 3 A average forward current at ≤30 V reverse voltage, features 315–360 mV forward voltage at 3 A/25 °C, and operates up to 150 °C junction temperature in a SOD128 (CFP5) surface-mount package - deployed in DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3030EP datasheet, PMEG3030EP pinout, PMEG3030EP application, or PMEG3030EP equivalent, key selection criteria include low VF performance under 3 A load, thermal resistance to solder point (12 K/W), reflow/wave solder compatibility, and SOD128 footprint compliance per IPC-7351B.
Technical Context
This Schottky diode uses clip-bond technology to enhance thermal conduction and power capability, enabling stable 3 A continuous operation with minimal forward voltage drop. Its planar structure and integrated guard ring improve robustness against electrical overstress and ESD transients without compromising switching speed.
The device exhibits low reverse recovery charge (Qrr ≈ 0 nC, inherent to Schottky architecture), making it suitable for high-frequency SMPS topologies. Diode capacitance is 470 pF at 1 V reverse bias (1 MHz), supporting fast transient response in buck converter freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 3 A - supports continuous 3 A DC or pulsed output in compact DC-DC modules without forced cooling |
| VR | 30 V - rated for 24 V rail systems with 20 % margin; not suitable for 48 V input stages |
| VF @ 3 A, 25 °C | 315–360 mV - reduces conduction loss by ~40 % vs. standard silicon diodes, improving efficiency in <5 V outputs |
| IR @ 30 V, 25 °C | 1.5–5 mA - higher leakage than ultra-low-leakage Schottkys but acceptable for non-battery-critical applications |
| Rth(j-sp) | 12 K/W - low thermal resistance from junction to cathode solder point enables direct heat transfer to PCB copper pour |
| Tj(max) | 150 °C - allows operation in sealed industrial enclosures with ambient up to 85 °C when mounted on FR4 with 1 cm² cathode pad |
Pinout & Package
Encapsulated in a SOD128 (CFP5) plastic surface-mount package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat leads for low-profile mounting and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked side with bar; connects to output rail or ground return path; primary thermal interface via exposed cathode tab |
| 2 (A) | Anode | Input or switching node connection; carries full forward current; no thermal pad attachment |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 315–360 mV @ 3 A ensures <0.9 W conduction loss, critical for thermally constrained 5 V/3 A point-of-load regulators |
| Integrated guard ring | Enhances ruggedness against voltage transients and localized ESD, extending reliability in unregulated input environments |
| Clip-bond construction | Improves thermal coupling between die and cathode tab, enabling 2.1 W total power dissipation on ceramic PCB |
| SOD128 package | Enables 0.65 mm profile height and IPC-7351B-compliant footprint for space-constrained USB-C PD and IoT power stages |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-002; supports lead-free reflow profiles up to 260 °C peak |
Applications
| DC-DC Buck Converter Freewheeling | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Freewheeling path in synchronous or asynchronous 5 V/3 A buck converter operating at 500 kHz. IC Role / Device Role / Timing Role: Unidirectional current path during low-side switch off-time; conducts inductive flyback energy. Use Value: 315–360 mV VF minimizes conduction loss, increasing efficiency by ≥1.2 % over comparable 450 mV Schottkys at full load. |
Use Scenario: Series protection on 12 V input rail of industrial sensor node with Li-ion backup. IC Role / Device Role / Timing Role: Forward-conducting series diode blocking reverse current during battery swap or supply fault. Use Value: 3 A rating handles cold-start inrush; 30 V VR accommodates 12 V ±10 % tolerance plus line transients. |
| USB-C Power Delivery Output Stage | Low-Voltage Rectification in PoE PD |
|
Use Scenario: Output rectification in 9 V/3 A USB-C PD sink circuit with integrated controller. IC Role / Device Role / Timing Role: Secondary-side rectifier replacing synchronous MOSFET where gate drive complexity must be minimized. Use Value: SOD128 footprint fits tight layout constraints; 1.0 mm height avoids interference with USB-C connector shield. |
Use Scenario: Auxiliary 3.3 V rail rectification in IEEE 802.3af/at Powered Device (PD) interface. IC Role / Device Role / Timing Role: Low-loss AC-to-DC conversion of PoE-derived 5 V intermediate bus before LDO regulation. Use Value: 360 mV max VF at 3 A keeps rectifier loss below 1.1 W, reducing thermal impact on isolated PD board area. |
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 NSS30300U | Same 30 V/3 A rating; VF = 340–400 mV @ 3 A; SOD-123FL package (smaller, no cathode thermal tab) | Limited thermal performance: Rth(j-a) = 250 K/W vs. PMEG3030EP's 60 K/W on ceramic PCB | Select when board space is critical and power dissipation ≤0.6 W; avoid in sustained 3 A loads. |
| Vishay VSSAF3M30-M3/84A | 30 V/3 A; VF = 320–370 mV @ 3 A; SMAF package (larger, 2.7 mm height) | Higher profile (2.7 mm) conflicts with low-profile USB-C or thin IoT enclosures | Prefer for manual assembly or wave-solder-only lines; use only if SOD128 footprint cannot be accommodated. |
Compared with NSS30300U and VSSAF3M30-M3/84A, PMEG3030EP uniquely balances ultra-low VF, SOD128 low-profile packaging, and 12 K/W junction-to-solder-point thermal resistance - making it optimal for thermally dense, high-efficiency 3 A DC-DC designs where height and thermal management are co-constrained.

FAQ
Is PMEG3030EP suitable for automotive applications?
No. Per Nexperia's revision history (v.3, April 2023), PMEG3030EP is explicitly non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade process controls, and extended temperature validation beyond 150 °C junction. For automotive use, select Nexperia's PMEG3030EP-Q series or equivalent AEC-Q101 Schottkys.
What is the maximum allowable soldering temperature for PMEG3030EP?
The device is qualified for lead-free reflow per J-STD-020, with a peak temperature of 260 °C for ≤30 seconds. Wave soldering is also supported using the footprint in Figure 16 (sod128_fw). Exceeding 260 °C risks delamination of the clip-bond interface and irreversible VF increase.
How does the guard ring affect surge robustness?
The integrated guard ring mitigates edge breakdown under high dv/dt or repetitive voltage overshoot (e.g., in SMPS turn-off events), increasing the device's ability to withstand 30 V transients without degradation. This is confirmed in Nexperia's stress testing per IEC 61000-4-5, though no specific surge rating is published.
Can PMEG3030EP replace a standard 1N5822 in existing designs?
Yes, with caveats: both are 3 A/40 V Schottkys, but PMEG3030EP has lower VR (30 V vs. 40 V) and significantly lower VF (315–360 mV vs. ~500 mV). Verify that 30 V VR provides sufficient margin for your input rail; if so, the SOD128 footprint requires PCB land pattern update from DO-201AD.
