Product details
Overview
PMEG2005AESFYL from Nexperia is a 20 V, 0.5 A low forward voltage Schottky barrier rectifier in a DSN0603-2 (SOD962-2) leadless chip-scale package, designed for ultra-compact DC-to-DC conversion and mobile LED backlighting where space and thermal efficiency are critical. It delivers typ. VF = 245 mV at 10 mA, typ. IR = 5 µA at 10 V, and trr < 2 ns - enabling high-frequency switching with minimal conduction loss.
For engineers reviewing the PMEG2005AESFYL datasheet, PMEG2005AESFYL pinout, PMEG2005AESFYL application, or PMEG2005AESFYL equivalent, key selection criteria include its 0.3 mm profile, 245 mV forward voltage at low current, 1.9 ns reverse recovery time, and compatibility with reflow-soldered ultra-small footprint designs on FR4 or ceramic PCBs.
Technical Context
This MEGA Schottky rectifier uses a planar silicon die with integrated guard ring for enhanced ESD and surge robustness. Its ultra-low VF stems from optimized metal-semiconductor interface design, not process scaling alone - delivering 245 mV at 10 mA while maintaining VR = 20 V.
The device operates without minority-carrier storage, resulting in trr < 2 ns and negligible reverse recovery charge. Thermal performance is defined by Rth(j-sp) = 40 K/W to anode solder point, making it suitable for thermally constrained layouts where junction-to-pad conduction dominates over ambient dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 mA | 245 mV typical - reduces conduction loss in low-voltage, high-efficiency buck converters |
| VR | 20 V maximum - supports input rails up to 18 V with margin for transient spikes |
| trr | 1.9 ns typical - enables stable operation above 10 MHz switching frequencies |
| IR @ 10 V | 5 µA typical - minimizes standby leakage in battery-powered systems |
| Package height | 0.3 mm typical - fits under 0.4 mm board-to-board connectors and thin display modules |
| IF(AV) | 0.5 A continuous - rated for sustained output in portable power rails with 115 °C ambient |
| Cd @ 10 V | 10 pF typical - limits capacitive coupling noise in high-dv/dt synchronous rectifier nodes |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless chip-scale package measuring 0.6 × 0.3 × 0.3 mm with exposed anode/cathode pads and no molded body - optimized for automated placement and reflow on fine-pitch PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side with bar; connects to output/ground node in step-down rectification |
| 2 | Anode (A) | Unmarked terminal; ties to switch node or input rail; serves as primary thermal path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents edge breakdown under mechanical stress or humidity exposure - improves field reliability in handheld assemblies |
| 0.3 mm max height | Enables stacking beneath OLED flex cables and within < 0.5 mm Z-height camera modules |
| Rth(j-sp) = 40 K/W | Allows 0.5 A average current with ≤ 20 °C temperature rise above solder point on standard FR4 |
| Low VF temperature coefficient | VF increases only ~0.2 mV/°C - maintains regulation stability across −40 °C to +125 °C junction range |
| 100% matte tin terminations | Ensures solderability after 12-month shelf life and compatibility with lead-free reflow profiles (peak 260 °C) |
Applications

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, 200 mV VF @ 10 mA, SOD-523 package (0.6 × 0.3 × 0.5 mm) | Higher voltage rating but 0.2 mm taller - unsuitable for sub-0.4 mm Z-height constraints | Select when VR margin >10 V is required and board height allows 0.5 mm profile |
| NSR0230HT1G | 30 V VR, 370 mV VF @ 100 mA, SOD-923 package (1.0 × 0.6 × 0.4 mm) | Higher VF degrades efficiency at >100 mA; larger footprint consumes 3× board area | Choose only if legacy layout requires SOD-923 pad stack and VR >25 V is mandatory |
Compared with RB521S-30T2R and NSR0230HT1G, PMEG2005AESFYL provides optimal balance of ultra-low height (0.3 mm), lowest VF at light loads (245 mV), and verified guard ring robustness - making it the preferred choice for next-gen mobile and wearable power stages where space and leakage are co-constrained.

FAQ
Is PMEG2005AESFYL suitable for automotive applications?
No. PMEG2005AESFYL is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. Nexperia explicitly states non-automotive qualification in its legal disclaimers, and the device is rated only for commercial/industrial temperature ranges (−55 °C to +150 °C junction), not extended automotive grades.
What is the recommended reflow profile for DSN0603-2 packaging?
The manufacturer specifies peak reflow temperature of 260 °C for 10–15 seconds, with ramp-up ≤ 3 °C/s and ramp-down ≤ 6 °C/s. The footprint must follow Figure 16: 0.24 mm wide solder lands with 0.4 mm center-to-center pitch and 0.14 mm solder resist opening - critical to prevent tombstoning due to asymmetric wetting of the 0.3 mm tall terminals.
How does the guard ring improve reliability in portable designs?
The integrated guard ring mitigates edge-related avalanche breakdown during board flexure, moisture ingress, or localized contamination - validated per IEC 61000-4-2 ESD testing (8 kV contact). In smartphone hinge regions or wearable wristband flex zones, this prevents latent parametric shift or catastrophic failure under mechanical stress that standard Schottky dies cannot withstand.
Can PMEG2005AESFYL replace PMEG2005AEB,115 in existing designs?
Yes, with verification. Both share identical electrical specs and DSN0603-2 package, but PMEG2005AESFYL uses a different marking code ('6') and updated wafer process. Thermal resistance and VF distribution are statistically aligned per Nexperia's v.2 datasheet revision - however, reflow profile validation and post-solder X-ray inspection are advised due to subtle solder paste volume sensitivity in the ultra-thin CSP.
