Product details
Overview
PMEG2005BELD 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 ≤390 mV forward voltage (IF = 500 mA), supports 20 V reverse voltage, and uses ultra-small DFN1006D-2 (SOD882D) package with solderable side pads.
For engineers reviewing the PMEG2005BELD datasheet, PMEG2005BELD pinout, PMEG2005BELD application, or PMEG2005BELD equivalent, key selection criteria include its low VF performance at 500 mA, thermal resistance to solder point (25 K/W), 1.6 ns reverse recovery time, and suitability for mobile LED backlight and ultra-high-speed switching where board area and power loss are critical.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under transient conditions. Its low barrier height enables fast carrier transport and minimizes forward conduction loss.
The device operates with negligible minority-carrier storage, resulting in near-zero reverse recovery charge (Qrr) and enabling efficient operation at frequencies up to several MHz. Its thermal design targets junction-to-solder-point transfer via the cathode tab, optimized for reflow-soldered FR4 or ceramic PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 500 mA | 353–390 mV - Enables <180 mW conduction loss at full rated current, critical for battery-powered efficiency. |
| VR | 20 V - Supports input rails up to 18 V in buck converters or USB-powered systems with margin. |
| IF(AV) | 0.5 A - Sustained DC output capability suitable for point-of-load regulators feeding microcontrollers or sensors. |
| trr | 1.6 ns - Permits clean switching in >1 MHz SMPS without tail current or ringing-induced EMI. |
| IR @ 20 V | 87–200 µA - Low leakage preserves standby current in always-on circuits like real-time clocks or wake-up logic. |
| Cd @ 1 V | 31–40 pF - Minimizes capacitive loading on high-speed switching nodes and improves transient response. |
| Rth(j-sp) | 25 K/W - Direct thermal path from junction to cathode solder point enables effective heat extraction on compact PCBs. |
Pinout & Package
Encapsulated in a leadless ultra-small DFN1006D-2 (SOD882D) package measuring 1.0 mm × 0.6 mm × 0.37 mm, with visible and solderable side pads for optical inspection and automated optical inspection (AOI) compatibility. Cathode identified by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; connected to PCB copper pour or thermal pad for heat dissipation and low-inductance return path. |
| 2 | Anode (A) | Current entry terminal; routed to switch node or input rail; minimal trace length required to reduce parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Improves ruggedness against EOS/ESD events without increasing VF or footprint-critical for unregulated input stages. |
| Solderable side pads | Enables reliable AOI and X-ray inspection of solder joints in ultra-fine-pitch assembly, reducing field failure risk. |
| 0.37 mm typical height | Allows stacking under thin-profile connectors or shields; compatible with <0.5 mm Z-height system designs. |
| Reflow-only soldering | Guarantees mechanical integrity and thermal performance-no hand-soldering or wave soldering permitted. |
Applications
| Mobile LED Backlight | USB-C Power Path Protection |
|---|---|
|
Use Scenario: Boost converter driving white LEDs in smartphone displays with dynamic brightness control. IC Role / Device Role / Timing Role: Output rectifier in synchronous boost topology, conducting during low-side switch off-time.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 30 V VR, 200 mA IF(AV), VF = 370 mV @ 100 mA - higher VR but lower current rating. | Not suitable for 0.5 A continuous loads; acceptable only in low-current bias or signal clamping roles. | Select only if system requires ≥25 V reverse margin and peak load stays below 200 mA. |
| NSR0530HT1G | 30 V VR, 0.5 A IF(AV), VF = 450 mV @ 500 mA - 60 mV higher VF, same package. | Higher conduction loss increases thermal stress in thermally constrained layouts. | Prefer when 30 V VR headroom is mandatory and 60 mW extra loss per diode is acceptable. |
Compared with RB520S-30T1G and NSR0530HT1G, PMEG2005BELD uniquely balances 20 V rating, 0.5 A capacity, and sub-390 mV VF in the smallest DFN1006D-2 footprint-making it optimal for miniaturized, battery-sensitive designs where every millivolt and cubic millimeter matters.

FAQ
What is the maximum allowable solder point temperature for PMEG2005BELD?
The absolute maximum solder point temperature (Tsp) is 140 °C, as defined in limiting values. Exceeding this risks delamination or intermetallic degradation at the cathode pad interface. Reflow profiles must maintain Tsp ≤ 140 °C with peak temperatures limited to 260 °C for ≤30 seconds, per JEDEC J-STD-020.
Can PMEG2005BELD be used in automotive applications?
No-PMEG2005BELD is explicitly non-automotive qualified per Nexperia's revision history (v.5, Nov 2022). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, select Nexperia's PMEG2005BELD-Q series or equivalent qualified Schottky rectifiers.
How does the guard ring affect electrical performance?
The integrated guard ring suppresses edge breakdown without altering the active junction's forward characteristics. It maintains the specified 20 V VR and 353–390 mV VF while improving surge robustness-verified by IEC 61000-4-5 testing-and extends device lifetime under repetitive voltage transients in unregulated inputs.
Is thermal derating required when mounted on FR4 versus ceramic PCB?
Yes-thermal derating is essential. On standard FR4 (1 cm² cathode pad), IF(AV) drops to 0.25 A at Tamb = 100 °C (Fig. 11); on Al₂O₃ ceramic, it remains 0.5 A up to 115 °C (Fig. 12). Designers must apply layout-specific derating curves-not generic ambient limits-to ensure junction temperature stays ≤150 °C.
