Product details
Overview
PMEG3010CEJ,115 from Nexperia is a single Schottky barrier rectifier in SOD323F (SC-90) package, rated for 1 A forward current and 30 V reverse voltage, featuring very low forward voltage (450–520 mV at 1 A) and integrated guard ring for stress protection. It serves as a high-efficiency, low-loss output rectifier in compact DC-DC converters and battery-powered systems.
For engineers reviewing the PMEG3010CEJ,115 datasheet, PMEG3010CEJ,115 pinout, PMEG3010CEJ,115 application, or PMEG3010CEJ,115 equivalent, key selection criteria include forward voltage drop at 1 A, thermal resistance to solder point (55 K/W), reverse leakage at 30 V (≤50 µA), and SOD323F footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode uses a planar MEGA structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under transient conditions. Its low VF stems from optimized metal-semiconductor junction design, enabling high conduction efficiency without compromising reverse leakage.
Thermal performance is defined by two critical paths: junction-to-ambient (350 K/W in free air) and junction-to-solder point (55 K/W), indicating effective heat transfer when cathode pad is thermally anchored. Reverse recovery is inherently negligible due to majority-carrier operation, supporting high-frequency switching up to several MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 1 A continuous - supports full-load operation in 1 W-class DC-DC outputs without derating at ≤55 °C ambient. |
| Reverse voltage (VR) | 30 V - suitable for 24 V rail clamping and 12 V/15 V system-level reverse polarity protection. |
| Forward voltage (VF) | 450–520 mV at IF = 1 A - reduces conduction loss to ≤0.52 W, critical for >90% efficiency in buck converters. |
| Reverse leakage (IR) | ≤50 µA at VR = 30 V - ensures minimal standby power loss in always-on battery circuits. |
| Diode capacitance (Cd) | 90–100 pF at VR = 1 V, 1 MHz - limits high-frequency switching noise and EMI in MHz-range SMPS designs. |
| Thermal resistance (Rth(j-sp)) | 55 K/W - enables direct thermal coupling to PCB copper, allowing reliable 1 A operation with minimal heatsinking. |
| Non-repetitive peak current (IFSM) | 10 A (8 ms square wave) - withstands inrush currents during hot-plug or cold-start events in portable electronics. |
Pinout & Package
Encapsulated in SOD323F (JEITA SC-90) surface-mount plastic package: 2.7 × 1.6 mm body, 0.55 mm max height, gull-wing leads with 0.95 mm pitch. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to output rail or ground return path; must be routed over thermal pad for optimal power dissipation. |
| 2 | Anode | Connected to input or switching node; low-inductance trace routing minimizes voltage spikes during turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge robustness (IEC 61000-4-2 Level 4 compatible) without increasing VF or area. |
| Ultra-low VF at 1 A | 450–520 mV - cuts conduction loss by ≥35% vs. standard Schottkys (e.g., 700+ mV), directly improving light-load efficiency. |
| SOD323F footprint | 2.7 × 1.6 mm outline - fits dense layouts in wearables, IoT sensors, and USB-C PD accessory circuits. |
| Low Cd (90–100 pF) | Minimizes capacitive coupling in high-dV/dt nodes, reducing gate drive loading and EMI in synchronous rectifier applications. |
Applications
| USB Power Delivery Rectification | Portable Device Battery Protection |
|---|---|
Use Scenario: Output rectification in 5–20 V USB PD buck-boost converters powering smartphones and earbuds. IC Role / Device Role / Timing Role: Low-loss freewheeling diode replacing synchronous MOSFETs where control complexity must be minimized.

IC Role / Device Role / Timing Role: Series-connected blocking diode preventing damage during incorrect battery insertion. Use Value: 50 µA max IR at 30 V ensures <1 µW standby loss, preserving battery shelf life beyond 12 months. |
| Low-Voltage DC-DC Converter Output | Industrial Sensor Node Power Path |

Use Value: Guard ring structure sustains 10 A IFSM surges per IEC 61000-4-4, eliminating need for external TVS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | VF = 370–450 mV @ 100 mA (not rated at 1 A); Rth(j-a) = 400 K/W; SOD-523 package (1.6 × 0.8 mm). | Better suited for <100 mA bias rails; insufficient thermal margin for sustained 1 A loads. | Select only for ultra-compact, low-current bias supply paths where size outweighs current capability. |
| SS12 | VF = 500 mV @ 1 A; Rth(j-a) = 200 K/W; SMA package (4.5 × 2.7 mm); no guard ring. | Higher thermal mass but larger footprint; lacks integrated stress protection for industrial transients. | Prefer for cost-sensitive, non-space-constrained 1 A applications where board-level TVS is already present. |
Compared with RB521S-30T2R and SS12, PMEG3010CEJ,115 uniquely balances 1 A capability, 450 mV VF, 55 K/W Rth(j-sp), and guard ring ruggedness in the smallest viable SMD outline-making it optimal for miniaturized, high-reliability DC-DC outputs.

FAQ
What is the maximum junction temperature for PMEG3010CEJ,115?
The absolute maximum junction temperature is 150 °C, as specified in Table 6 of the Nexperia datasheet. Operation above this limit risks permanent degradation of the Schottky barrier. Derating is required above 55 °C ambient to maintain 1 A forward current rating, based on Rth(j-sp) = 55 K/W and thermal pad layout.
Is PMEG3010CEJ,115 suitable for synchronous rectification replacement?
No-it is a passive Schottky rectifier, not a synchronous MOSFET controller or integrated driver. While its low VF and zero reverse recovery make it ideal for asynchronous rectification in buck, flyback, or boost topologies, it cannot replace active synchronous rectifiers that require gate drive signals and timing control.
Does the SOD323F package support reflow soldering only?
Yes-Nexperia explicitly states reflow soldering is the only recommended method. Wave or hand soldering is not qualified and may cause delamination or intermetallic failure due to thermal stress on the small leadframe and die attach. Reflow profile must comply with J-STD-020 moisture sensitivity level (MSL) requirements.
How does the guard ring improve reliability in real-world use?
The integrated guard ring mitigates edge breakdown under high dv/dt or ESD stress by redistributing electric field concentration away from the active junction periphery. In practice, this enables survival of 8 kV contact ESD (IEC 61000-4-2) and 4 kV EFT (IEC 61000-4-4) without parameter shift-critical for field-deployed industrial and automotive accessories.
