Product details
Overview
PMEG4005EPK 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 in space-constrained portable electronics. It delivers 0.5 A average forward current at ≤590 mV forward voltage (IF = 500 mA), supports 40 V reverse voltage, and features ultra-fast 2 ns reverse recovery time.
For engineers reviewing the PMEG4005EPK datasheet, PMEG4005EPK pinout, PMEG4005EPK application, or PMEG4005EPK equivalent, key selection criteria include its low VF performance at 500 mA, side-wettable DFN1608D-2 package for automated optical inspection, 0.37 mm profile for thin mobile designs, and thermal resistance of 150 K/W on FR4 PCB.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low barrier height enables sub-600 mV forward drop at rated current while maintaining <2 µA reverse leakage at 10 V and 25 °C.
The device operates without minority-carrier storage, enabling true zero-recovery behavior - confirmed by trr ≤ 2 ns under IF = IR = 0.5 A conditions. Its DFN1608D-2 package places solderable side pads at 0.94 mm pitch, supporting reflow-only assembly and AOI-compatible solder joint inspection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 500 mA | 530–590 mV - Enables ≥92% efficiency in 3.3 V → 1.2 V buck converters at full load |
| VR | 40 V - Supports input rails up to 36 V nominal in industrial or automotive accessory power supplies |
| trr | ≤ 2 ns - Eliminates switching node ringing in >1 MHz SMPS designs without snubbers |
| IR @ 10 V | 0.4–2 µA - Minimizes standby power loss in battery-backed systems (e.g., RTC backup) |
| Package | DFN1608D-2 (SOD1608) - 1.6 × 0.8 × 0.37 mm body with side-wettable flanks for IPC Class 3 solder joint verification |
| Tj max | 150 °C - Allows operation in sealed enclosures with ambient up to 125 °C when mounted on FR4 with cathode pad |
| Rth(j-sp) | 20 K/W - Enables direct thermal coupling to PCB copper, critical for pulsed 2 A IFRM handling |
Pinout & Package
Encapsulated in a leadless, ultra-small DFN1608D-2 (SOD1608) plastic package with visible and solderable side pads, 0.94 mm pitch, and 0.37 mm typical height. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Primary current exit path; connected to largest PCB copper pour for thermal dissipation and EMI control |
| 2 (A) | Anode | Input-side terminal; routed with minimal loop area to reduce switching noise coupling in buck high-side position |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge avalanche, enabling stable 40 V VR rating without derating in humid or contaminated environments |
| Solderable side pads | Enables automated optical inspection (AOI) of solder fillets - essential for Class III consumer and medical PCBAs |
| Low profile (0.37 mm) | Fits beneath 0.4 mm Z-height shields in smartphones and wearables without mechanical interference |
| Reflow-only assembly | Eliminates need for wave or selective soldering; compatible with standard Pb-free reflow profiles (J-STD-020) |
| Ultra-low Cd (10–15 pF @ 10 V) | Reduces capacitive switching loss and EMI in >2 MHz point-of-load regulators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G (ON Semiconductor) | Same 40 V VR, but VF = 600 mV @ 500 mA; SOD-523 package (1.3 × 0.85 mm); no side-wettable flanks | Lacks AOI capability; 0.5 mm height limits use in ultra-thin devices | Select only if footprint compatibility with legacy SOD-523 layouts is required and AOI is not mandated |
| NSR0540HT1G (onsemi) | VF = 450 mV @ 500 mA, but VR = 40 V; SOD-123FL package (2.8 × 1.7 mm); 1.1 mm height | Lower VF improves efficiency, but larger size blocks routing in dense RF sections | Prefer for high-efficiency 12 V input converters where board area is unconstrained |
Compared with RB520S-40T1G and NSR0540HT1G, PMEG4005EPK uniquely balances ultra-low profile, AOI-ready side pads, and sub-600 mV VF - making it optimal for next-gen mobile power stages where thickness, inspection yield, and efficiency are co-constrained.

FAQ
Is PMEG4005EPK suitable for automotive applications?
No. Per Nexperia's revision history (v.4, October 2025), PMEG4005EPK is explicitly designated non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade traceability. For automotive use, Nexperia recommends the -Q qualified variant PMEG4005EPK-Q, which undergoes extended temperature cycling and humidity testing.
What is the maximum allowable soldering temperature profile for PMEG4005EPK?
PMEG4005EPK requires reflow-only soldering per J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat (150–200 °C) and soak (200–220 °C) durations must stay within manufacturer-specified limits to avoid delamination of the DFN1608D-2 mold compound.
How does the guard ring affect layout requirements?
The integrated guard ring increases die edge ruggedness but requires ≥0.2 mm clearance between the cathode pad edge and any adjacent copper pour or via. This prevents field crowding that could negate the guard ring's benefit. Layouts must follow Nexperia's SOD1608 footprint (Fig. 18), including 0.75 mm solder land width and 0.1 mm solder resist opening.
Can PMEG4005EPK replace a standard PN diode in a 5 V buck converter?
Yes - with measurable improvement. Replacing a 1N5819 (VF ≈ 450 mV @ 500 mA, trr ≈ 40 ns) with PMEG4005EPK reduces conduction loss by ~10% and eliminates reverse recovery loss, increasing light-load efficiency by 3–5%. However, its lower IR (sub-2 µA vs. 500 µA) also reduces leakage-related standby drain in always-on circuits.
