Product details
Overview
PMEG2005AEL-QYL from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated for 0.5 A continuous forward current and 20 V reverse voltage, featuring ultra-low forward voltage (375–440 mV at 500 mA) in a leadless SOD882 package; used in high-efficiency DC-DC converters and low-voltage clamping circuits.
For engineers reviewing the PMEG2005AEL-QYL datasheet, PMEG2005AEL-QYL pinout, PMEG2005AEL-QYL application, or PMEG2005AEL-QYL equivalent, key selection criteria include forward voltage at 500 mA, reverse leakage at 20 V, junction-to-ambient thermal resistance, diode capacitance at 1 V, and SOD882 footprint compatibility with ultra-compact PCB layouts.
Technical Context
This Schottky rectifier employs a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF enables minimal conduction loss in low-voltage power paths.
Designed for operation up to 150 °C junction temperature, it exhibits reverse leakage of 370–1500 μA at 20 V and 25 °C, and 19–25 pF capacitance at 1 V/1 MHz - critical for high-frequency switching and EMI-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 0.5 A continuous - supports compact DC-DC output rectification without forced cooling |
| Reverse Voltage (VR) | 20 V - suitable for 12 V rail clamping and 5 V/3.3 V system protection |
| Forward Voltage (VF) | 375–440 mV at 500 mA - reduces conduction loss by >40% vs. standard Schottkys at same current |
| Reverse Leakage (IR) | 370–1500 μA at VR = 20 V - impacts standby power in always-on low-power systems |
| Diode Capacitance (Cd) | 19–25 pF at VR = 1 V, f = 1 MHz - enables <1 ns switching in high-frequency flyback snubbers |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air - requires minimal copper area for thermal management in space-constrained designs |
Pinout & Package
Encapsulated in a leadless ultra-small SOD882 plastic package (1.0 × 0.6 × 0.5 mm), with exposed die pad for thermal enhancement and top-side marking bar indicating cathode polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to negative output or ground return path; marked by bar on top surface |
| 2 | Anode | Connected to input or switched node; carries forward current into load or clamp path |
Key Features
| Feature | Design Value |
|---|---|

| Integrated guard ring | Suppresses edge breakdown under dv/dt stress, improving robustness in fast-switching SMPS |
| SOD882 leadless package | 1.0 × 0.6 mm footprint saves >65% board area vs. SOT23 while maintaining comparable power dissipation |
| 150 °C max junction temperature | Supports operation in sealed enclosures or thermally dense modules without derating at 85 °C ambient |
Applications
| DC-DC Converter Output Rectification | Voltage Clamping in USB Power Delivery |
|---|---|
Use Scenario: Synchronous rectifier replacement in 3.3 V/5 V buck converters for wearables and IoT sensors. IC Role / Device Role: Low-loss freewheeling diode during high-side FET off-time. Use Value: 375–440 mV VF minimizes conduction loss, extending battery life by up to 8% over standard Schottkys at 500 mA load. |
Use Scenario: Overvoltage clamp on VBUS line during USB PD negotiation transients. IC Role / Device Role: Fast-turn-on shunt protector limiting peak voltage to ≤20 V. Use Value: 19–25 pF capacitance avoids signal integrity degradation on 100 MHz CC lines while clamping sub-100 ns spikes. |
| Low-Power Logic-Level Protection | ESD-Sensitive Signal Line Guarding |
Use Scenario: Reverse-polarity and backfeed protection for 1.8 V/3.3 V MCU I/O rails. IC Role / Device Role: Series blocking diode with minimal forward drop in supply path. Use Value: 75–110 mV VF at 1 mA ensures <10 mV rail sag during sleep-mode leakage currents. |
Use Scenario: Input protection for analog sensor interfaces (e.g., I²C, ADC inputs) in industrial nodes. IC Role / Device Role: Low-capacitance shunt limiter diverting ESD pulses to ground. Use Value: 25 pF max capacitance preserves bandwidth >100 MHz while handling ±8 kV HBM per IEC 61000-4-2. |
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, SOD-523 package (1.2 × 0.8 mm), VF = 370 mV @ 100 mA | Lower current rating limits use to <200 mA loads; larger footprint than SOD882 | Select when higher reverse voltage margin is required and current demand is ≤200 mA |
| NSR0230P2T5G | 30 V VR, 200 mA IF, SOD-923 package (1.0 × 0.6 mm), VF = 370 mV @ 100 mA | Same footprint as SOD882 but lower IF rating; no guard ring structure | Prefer for cost-sensitive 200 mA apps where edge reliability under dv/dt is not critical |
Compared with RB520S-30T1G and NSR0230P2T5G, PMEG2005AEL-QYL delivers 2.5× higher forward current in the same ultra-small footprint and includes guard ring protection - making it optimal for 500 mA DC-DC outputs where thermal density and transient robustness are prioritized.

FAQ
Is PMEG2005AEL-QYL suitable for automotive applications?
Yes - it is qualified to AEC-Q101, operates from −65 °C to +150 °C, and features a guard ring for enhanced dv/dt immunity, making it appropriate for under-hood DC-DC converters and body control module power rails where thermal and electrical stress are elevated.
What is the maximum allowable soldering temperature for SOD882 reflow?
The SOD882 package supports standard lead-free reflow profiles with peak temperature up to 260 °C for ≤30 seconds, per JEDEC J-STD-020. The device's 150 °C Tj rating and thermal design ensure reliability under these conditions when mounted on FR4 with recommended 0.5 mm² copper pad.
How does the guard ring affect reverse recovery behavior?
The integrated guard ring eliminates minority-carrier injection and associated stored charge, resulting in true zero reverse recovery time (trr ≈ 0 ns). This prevents shoot-through in synchronous rectifiers and eliminates ringing in high-dv/dt snubber circuits.
Can PMEG2005AEL-QYL replace a standard silicon diode in a 5 V supply rail?
Yes - with VF as low as 375 mV at 500 mA, it reduces forward drop by ~65% versus a typical 1N4148 (VF ≈ 1.0 V), cutting conduction loss by >60% and enabling cooler, more efficient 5 V rail protection or OR-ing functions without redesigning layout or thermal pads.
