Product details
Overview
PMEG2005EPK 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 0.5 A average forward current at ≤410 mV forward voltage (IF = 500 mA), supports 20 V reverse voltage, exhibits ultra-fast 3 ns reverse recovery time, and is packaged in a leadless DFN1608D-2 (SOD1608) with solderable side pads.
For engineers reviewing the PMEG2005EPK datasheet, PMEG2005EPK pinout, PMEG2005EPK application, or PMEG2005EPK equivalent, this device is selected for space-constrained mobile power rails where low VF, minimal thermal resistance (85 K/W to solder point), and reliable low-current rectification are critical - especially in LED backlight and ultra-low-power subsystems.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve robustness under transient stress. Its low 360–410 mV VF at 500 mA enables high efficiency in 3.3 V and lower input DC-DC stages.
The DFN1608D-2 package features side-wettable flanks for automated optical inspection (AOI) of solder joints and achieves Rth(j-sp) = 20 K/W to cathode solder point - enabling effective thermal management on compact PCBs without thermal vias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 500 mA | 360–410 mV - Enables ≥92% efficiency in 1.8–3.3 V buck converter freewheeling paths |
| VR | 20 V - Rated for use in 12 V and 15 V auxiliary rails with margin against transients |
| trr | 3 ns - Supports switching frequencies >5 MHz without reverse recovery loss penalty |
| IR @ 10 V | 30–130 µA - Low leakage preserves battery life in always-on mobile subsystems |
| Package | DFN1608D-2 (SOD1608), 1.6 × 0.8 × 0.37 mm - Fits 0603 footprint area with enhanced thermal and solder-joint visibility |
| Rth(j-sp) | 20 K/W - Direct thermal path to cathode pad enables >0.5 A continuous operation on 1 cm² copper |
Pinout & Package
Encapsulated in a leadless ultra-small DFN1608D-2 (SOD1608) 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 (K) | Cathode | Main current exit terminal; connected to ground or return path; thermally coupled to PCB mounting pad |
| 2 (A) | Anode | Current entry terminal; connects to switched node or input rail; side-wettable flank aids AOI |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 360–410 mV at 500 mA reduces conduction loss by >40% vs. standard PN diodes in 3.3 V rails |
| Integrated guard ring | Suppresses edge leakage and improves surge robustness - critical for unregulated input stages |
| Solderable side pads | Enables automated optical inspection (AOI) of solder fillets without X-ray, improving manufacturing yield |
| Ultra-low profile (0.37 mm) | Allows stacking under thin-film shields or beneath connectors in slim mobile designs |
Applications
| Mobile LED Backlight | USB-C Power Path Protection |
|---|---|
|
Use Scenario: Driving white LEDs from a 5 V boost converter in smartphones and tablets. IC Role / Device Role / Timing Role: Freewheeling diode in boost inductor return path; conducts during low-side switch off-time. Use Value: 410 mV VF minimizes voltage headroom loss, enabling higher LED current within 5 V input constraint. |
Use Scenario: Reverse polarity protection between USB-C receptacle and internal 5 V rail. IC Role / Device Role / Timing Role: Series blocking diode preventing damage when external adapter is inserted backward. Use Value: 20 V VR rating and 0.5 A IF(AV) support full 3 A USB-C PD negotiation while limiting forward drop to <410 mV. |
| Wearable Battery Charging | IoT Sensor Node Power Rail |
|
Use Scenario: Isolating charging path from battery in coin-cell–powered wearables with linear charger ICs. IC Role / Device Role / Timing Role: Unidirectional isolation diode between charger output and battery terminal. Use Value: 30–130 µA IR at 10 V prevents measurable self-discharge over weeks of standby. |
Use Scenario: Supply rail OR-ing in dual-source (battery + energy harvester) sensor nodes. IC Role / Device Role / Timing Role: Low-loss diode enabling seamless source switchover without control logic. Use Value: 3 ns trr avoids cross-conduction during fast source transitions; 0.37 mm height fits under RF shields. |
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 | 30 V VR, 0.2 A IF(AV), VF = 370 mV @ 100 mA - lower current rating, higher VR | Better suited for 24 V industrial sensors; insufficient for 0.5 A DC-DC outputs | Select only if VR margin >10 V required and peak current stays below 0.25 A |
| NSR0230HT1G | 30 V VR, 0.2 A IF(AV), VF = 450 mV @ 200 mA - higher VF, same package footprint | Higher conduction loss limits use in battery-sensitive apps; no guard ring | Acceptable only where VR >20 V is mandatory and efficiency loss <5% is tolerable |
Compared with RB521S-30T2R and NSR0230HT1G, PMEG2005EPK uniquely balances 0.5 A current capability, 20 V rating, sub-410 mV VF, and guard-ring reliability - making it optimal for space-limited 3.3/5 V mobile power rails where both efficiency and surge resilience matter.

FAQ
Is PMEG2005EPK automotive qualified?
No. Per Nexperia's revision history (v.4, Sept 2025), PMEG2005EPK is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive applications, Nexperia offers separate -Q qualified variants such as PMEG2005EPK-Q, which must be specified separately.
What is the maximum continuous forward current at 85 °C ambient?
At Tamb = 85 °C on an FR4 PCB with standard footprint, PMEG2005EPK supports 0.5 A average forward current (δ = 0.5, f = 20 kHz square wave), per Figure 10. Derating begins above 85 °C ambient, reaching 0.25 A at 125 °C.
Can PMEG2005EPK replace a standard 1N5817 in a 5 V supply?
Yes - with caveats. Its 20 V VR exceeds 1N5817's 20 V rating, and 410 mV VF is lower than 1N5817's typical 450 mV. However, PMEG2005EPK's DFN1608D-2 package requires reflow-compatible layout and side-wettable pad design, unlike through-hole or SMA packages used for 1N5817.
Does the cathode marking bar indicate polarity during board assembly?
Yes. The marking bar on the top surface of the DFN1608D-2 package aligns with Pin 1 (cathode), as confirmed in Table 2 and Figure 17. This orientation must match the silkscreen polarity indicator on the PCB to ensure correct anode–cathode connection and prevent reverse bias failure.
