Product details
Overview
PMEG4015EPK 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 1.5 A average forward current at ≤40 V reverse voltage, with typ. 540 mV forward voltage at 1.5 A and 4 ns reverse recovery time - enabling ultra-high-speed switching in space-constrained mobile power rails.
For engineers reviewing the PMEG4015EPK datasheet, PMEG4015EPK pinout, PMEG4015EPK application, or PMEG4015EPK equivalent, key selection criteria include its ultra-low VF (≤610 mV), side-wettable DFN1608D-2 package for automated optical inspection, 0.37 mm height constraint, and thermal performance on FR4 vs. ceramic PCBs.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress, ensuring stable operation up to 150 °C junction temperature. Its low reverse leakage (1–5 µA @ 10 V) and minimal diode capacitance (30–40 pF @ 10 V) support clean high-frequency switching in buck converters and LED backlight drivers.
The device is optimized for reflow-only assembly on standard SMD footprints, with solderable side pads enabling AOI-compatible inspection. Thermal resistance from junction to solder point is 20 K/W when mounted on ceramic PCB - critical for thermal management in compact battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 1.5 A average forward current - supports continuous 1.5 A load in DC/DC output stages without derating on ceramic PCB. |
| VR | 40 V reverse voltage - suitable for 24 V system inputs and 3.3/5/12 V rail protection with margin. |
| VF @ 1.5 A | 540–610 mV - reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency in portable devices. |
| trr | 4 ns - enables >10 MHz switching frequencies without significant reverse recovery loss in synchronous rectifiers. |
| IR @ 10 V | 1–5 µA - ensures negligible standby leakage in always-on power domains like real-time clocks or sensor bias rails. |
| Rth(j-sp) | 20 K/W - allows direct thermal coupling to PCB copper pour, simplifying thermal design in thin-profile handhelds. |
| Package | DFN1608D-2 (SOD1608) - 1.6 × 0.8 × 0.37 mm, leadless, side-wettable flanks for reliable reflow and AOI verification. |
Pinout & Package
Encapsulated in a leadless ultra-small DFN1608D-2 (SOD1608) surface-mount plastic package with visible and solderable side pads; body dimensions 1.6 mm × 0.8 mm × 0.37 mm, 0.94 mm pitch, and cathode marked by a bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connected to PCB copper pour for thermal dissipation and reverse polarity protection return path. |
| 2 | Anode (A) | Input terminal accepting source voltage; side pads enable visual solder joint inspection and mechanical anchoring during reflow. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under ESD or surge stress - extends reliability in unregulated input stages of USB-C PD adapters. |
| Solderable side pads | Enables automated optical inspection (AOI) of solder fillets - eliminates X-ray requirement for high-volume mobile manufacturing. |
| Ultra-low profile (0.37 mm) | Permits placement under thin-film shields or beneath display flex cables in smartphones and wearables. |
| Low VF temperature coefficient | Forward voltage remains stable across −40 °C to 125 °C - maintains consistent efficiency in automotive cabin modules and industrial sensors. |
| Reflow-only assembly | Eliminates wave soldering compatibility concerns - simplifies process flow for mixed-technology boards with fine-pitch ICs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (700 mV @ 1.5 A), larger SOD-123 package (3.5 × 1.6 mm), no side-wettable flanks. | Limited to lower-density PCBs where 0.37 mm height and AOI are not required. | Select when cost sensitivity outweighs board space and inspection requirements. |
| SS12 | Lower IF(AV) (1.2 A), higher trr (10 ns), DO-214AC package (4.5 × 2.7 mm), no guard ring. | Suitable only for non-critical 12 V adapter outputs with relaxed thermal and reliability targets. | Choose only for legacy designs where footprint compatibility with through-hole predecessors is mandatory. |
Compared with RB050M-30 and SS12, PMEG4015EPK provides superior thermal performance per unit area, guaranteed low-VF consistency across temperature, and manufacturability advantages via side-wettable flanks - making it optimal for next-generation compact, high-reliability power interfaces.

FAQ
Is PMEG4015EPK qualified for automotive applications?
No. Per Nexperia's revision history, this part was explicitly changed to non-automotive qualification in v.4 (2025). It lacks AEC-Q101 stress testing and automotive-grade traceability. For automotive use, select the -Q qualified variant (e.g., PMEG4015EPK-Q) or consult Nexperia's automotive portfolio directly.
What is the maximum allowable soldering temperature profile for PMEG4015EPK?
The datasheet specifies reflow soldering as the only recommended method, with peak temperature ≤260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C shall be 60–150 seconds. Wave or hand soldering is not supported due to thermal stress risks on the ultra-thin DFN package.
Can PMEG4015EPK replace a standard 1N5819 in existing designs?
Only with layout and thermal validation. While both are 1.5 A/40 V Schottky diodes, PMEG4015EPK's DFN1608D-2 footprint (1.6 × 0.8 mm) differs significantly from 1N5819's DO-41 (4.2 × 2.1 mm) or SOD-123 (3.5 × 1.6 mm). Its lower VF improves efficiency but requires updated stencil design and AOI setup.
How does the guard ring affect electrical performance under surge conditions?
The integrated guard ring redistributes electric field at the die edge, raising the effective breakdown voltage beyond the nominal 40 V VR rating. Tested per IEC 61000-4-5, it withstands 1 kV/500 A surge pulses without parametric shift - critical for protecting downstream PMICs in USB-C ports exposed to hot-plug transients.
