Product details
Overview
PMEG3020BER from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 2 A average forward current at ≤30 V reverse voltage, with a typical forward voltage of 460 mV at 2 A and 25 °C, housed in a compact SOD123W (CFP3) surface-mount package.
For engineers reviewing the PMEG3020BER datasheet, PMEG3020BER pinout, PMEG3020BER application, or PMEG3020BER equivalent, key selection criteria include low VF performance under 2 A load, thermal resistance to solder point (18 K/W), reverse leakage <50 µA at 30 V, clip-bond packaging for enhanced power capability, and compatibility with FR4 and ceramic PCB layouts.
Technical Context
This Schottky diode employs a planar die structure with an integrated guard ring to improve surge robustness and reduce field crowding at the junction edge. Its low forward voltage stems from optimized metal–semiconductor contact and thin epitaxial layer design, enabling high conduction efficiency without compromising reverse leakage.
The device uses clip-bond interconnection technology-replacing traditional wire bonding-to lower parasitic inductance and thermal resistance while increasing current-carrying capacity. Thermal performance is specified across three mounting conditions: standard FR4, enlarged cathode pad (1 cm²), and ceramic Al₂O₃ PCBs, supporting design flexibility in thermally constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A average forward current - supports continuous 2 A DC or pulsed operation up to 135 °C solder point temperature |
| VR | 30 V reverse voltage - rated for use in ≤30 V systems with margin against transients |
| VF @ 2 A | 460–520 mV - enables >92% efficiency in 5 V–12 V buck converters at full load |
| IR @ 30 V | 15–50 µA - low leakage preserves battery life in always-on low-power circuits |
| Rth(j-sp) | 18 K/W - low thermal resistance from junction to cathode solder point improves power handling on FR4 |
| Cd @ 10 V | 60 pF - low junction capacitance minimizes switching losses in high-frequency SMPS |
| IFSM | 50 A non-repetitive peak - withstands short-duration inrush or fault currents in power rails |
Pinout & Package
Encapsulated in the SOD123W (CFP3) plastic surface-mount package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, single-row 2-terminal configuration. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output/ground side of rectification path; marking bar identifies this terminal; serves as primary thermal path via solder pad |
| 2 (A) | Anode | Connected to input/high-side of rectification path; carries full forward current into the Schottky junction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD and transient surge immunity without external components, improving reliability in noisy industrial environments |
| Clip-bond construction | Reduces bond wire inductance and thermal resistance versus wire-bonded equivalents, enabling higher current density and faster switching |
| SOD123W footprint | Enables high-density PCB layout with standardized reflow-compatible land pattern (1.1 mm × 1.4 mm pads, 0.1 mm stencil) |
| Low VF over temperature range | Maintains <520 mV VF up to 125 °C junction, ensuring stable efficiency in thermally demanding enclosures |
| Non-automotive qualified | Designed for industrial, consumer, and computing applications-not validated per AEC-Q101; automotive users must select -Q variants |
Applications
| USB Power Delivery Protection | Point-of-Load DC-DC Output Rectification |
|---|---|
Use Scenario: Preventing reverse current flow from downstream USB-C PD ports during hot-plug or source-sink role swap. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between VBUS and system rail to enforce current directionality. Use Value: 460 mV VF minimizes voltage drop and heat generation at 2 A, preserving PD negotiation headroom and reducing thermal derating. |
Use Scenario: Synchronous rectifier replacement in 3.3 V/5 V buck converter outputs where gate drive complexity is undesirable. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side FET off-time in non-synchronous buck topology. Use Value: 60 pF capacitance and fast recovery enable clean switching at 500 kHz–1 MHz, reducing ringing and EMI vs. standard PN diodes. |
| Reverse Polarity Input Protection | Low-Power IoT Sensor Rail Clamp |
Use Scenario: Protecting 24 V industrial sensor inputs from accidental reverse battery connection. IC Role / Device Role / Timing Role: Series-connected anode-to-input diode that blocks reverse voltage while passing forward current. Use Value: 30 V VR rating provides 20 % margin above nominal 24 V supply, and 50 A IFSM handles brief connection surges without failure. |
Use Scenario: Clamping supply rail to prevent backfeed from coin-cell backup in ultra-low-power environmental sensors. IC Role / Device Role / Timing Role: Isolation diode between main LDO output and backup battery path to eliminate quiescent drain. Use Value: 15 µA max IR at 30 V ensures <1 µA standby leakage, extending 10-year battery life targets in wireless sensor nodes. |
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 NSR3020HT1G | Same SOD123W package, 30 V/2 A rating, but VF = 490–550 mV @ 2 A - 30–90 mV higher than PMEG3020BER | Higher VF increases conduction loss in high-duty-cycle applications; suitable where thermal margin exists | Select when ON Semi sourcing is preferred and 30 mV VF penalty is acceptable for BOM consolidation |
| Vishay SS23-M3/84A | SOD-123 package (not SOD123W), 30 V/2 A, VF = 500 mV @ 2 A, Rth(j-a) = 125 K/W - 5× higher than PMEG3020BER's Rth(j-sp) | Limited thermal performance on FR4; not recommended for >1 A continuous on standard PCBs | Choose only for legacy designs using SOD-123 footprint; avoid in new thermal-constrained layouts |
Compared with NSR3020HT1G and SS23-M3/84A, PMEG3020BER offers the lowest VF and best thermal coupling to PCB, making it optimal for space- and thermally constrained 2 A rectification where efficiency and reliability are prioritized over second-source flexibility.

FAQ
What is the maximum junction temperature for continuous operation?
The PMEG3020BER has a maximum junction temperature (Tj) of 150 °C. Continuous operation at this limit requires adherence to thermal derating curves in Figures 9–11 of the datasheet, with ambient or solder-point temperature constraints depending on PCB construction (FR4 vs. ceramic). At 135 °C solder point, IF(AV) remains rated at 2 A under specified duty cycle and waveform conditions.
Can PMEG3020BER be used in automotive applications?
No - PMEG3020BER is explicitly designated as non-automotive qualified per Section 14 revision history. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive use, engineers must select Nexperia's automotive-qualified equivalents (e.g., PMEG3020BER-Q series) which include extended temperature validation and PPAP documentation.
How does the guard ring improve reliability?
The integrated guard ring reduces electric field concentration at the Schottky junction periphery, suppressing premature avalanche breakdown and enhancing resistance to electrostatic discharge (ESD) and repetitive voltage transients. This design feature extends operational lifetime in environments with frequent load dumps or inductive switching noise, without requiring external TVS components.
Is the SOD123W footprint compatible with standard SOD-123 reflow profiles?
Yes - the SOD123W package shares identical pad dimensions and thermal mass characteristics with standard SOD-123, and Nexperia provides dedicated reflow footprint data (Figure 15) confirming compatibility with IPC-7095-compliant profiles. The "W" denotes wider lead spacing, but the land pattern remains interchangeable with legacy SOD-123 tooling and stencil designs.
