Product details
Overview
PMEG2005ESFYL from Nexperia is a 20 V, 0.5 A low forward voltage Schottky barrier rectifier in an ultra-small DSN0603-2 (SOD962-2) chip-scale package, designed for high-efficiency DC-to-DC conversion and mobile LED backlighting where space and thermal performance are critical. It delivers typ. VF = 310 mV at 10 mA, typ. IR = 0.37 µA at 10 V, and trr < 2 ns - enabling ultra-high-speed switching with minimal conduction loss.
For engineers reviewing the PMEG2005ESFYL datasheet, PMEG2005ESFYL pinout, PMEG2005ESFYL application, or PMEG2005ESFYL equivalent, key selection criteria include its 0.3 mm profile, 1.9 ns reverse recovery time, cathode-marked 2-terminal CSP layout, and suitability for thermally constrained portable power rails.
Technical Context
This MEGA Schottky rectifier uses a planar silicon die with integrated guard ring for robust ESD and surge stress protection. Its low-junction-capacitance (9 pF at 10 V) and sub-2 ns trr support operation in MHz-range switching topologies without significant switching loss penalties.
The device operates within a −55 °C to 150 °C junction temperature range and achieves Rth(j-sp) = 40 K/W when soldered to optimized pads - making it suitable for high-density PCBs where thermal path design directly governs current derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 20 V maximum reverse voltage - sets safe operating limit in 12 V and lower DC bus applications |
| IF(AV) | 0.5 A average forward current - supports continuous output in compact buck converters |
| VF | 310 mV typical at 10 mA - reduces conduction loss and self-heating in low-voltage, high-duty-cycle paths |
| trr | 1.9 ns typical - enables clean turn-off in >1 MHz PWM circuits without tail current or ringing |
| IR | 0.37 µA typical at 10 V - minimizes leakage-induced standby power loss in battery-powered systems |
| Package | DSN0603-2 (SOD962-2), 0.6 × 0.3 × 0.3 mm - fits 0201 footprint with exposed thermal terminals |
| Rth(j-sp) | 40 K/W - allows direct thermal coupling to copper pour for localized heat extraction |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, surface-mount chip-scale package with two solderable terminals and a 0.3 mm nominal height. The marking bar on the top surface identifies Pin 1 as the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connects to load ground or return path in buck/flyback secondary |
| 2 | Anode (A) | Input terminal for forward conduction; ties to switch node or input rail; serves as primary thermal interface |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ruggedness against ESD and transient overvoltage without increasing VF or size |
| Ultra-low profile (0.3 mm) | Enables stacking under thin-film shields or beneath display modules in smartphones and wearables |
| Low Cd = 9 pF at VR = 10 V | Reduces capacitive switching loss and noise coupling in high-frequency synchronous rectifiers |
| Thermal resistance Rth(j-sp) = 40 K/W | Permits 0.5 A operation at ≤110 °C ambient when mounted on 1 cm² anode/cathode pads |
| Marking bar identification | Eliminates optical inspection ambiguity during automated placement and AOI verification |
Applications
| Mobile LED Backlighting | USB-C Power Delivery Output Rectification |
|---|---|
|
Use Scenario: Driving white LEDs in smartphone displays using boost converter with synchronous rectification.

IC Role / Device Role / Timing Role: Fast-recovery output rectifier minimizing reverse recovery loss during high-frequency flyback transitions. Use Value: 1.9 ns trr avoids shoot-through risk and eliminates snubber requirements, reducing BOM count by one RC network per channel. |
| Wearable Sensor Power Rail | Low-Power IoT Node DC/DC Converter |
|
Use Scenario: Supplying regulated 1.8 V to MEMS accelerometers and BLE SoCs from coin-cell or energy-harvesting sources. IC Role / Device Role / Timing Role: Input protection and reverse polarity blocking diode in ultra-low-quiescent buck-boost architecture. Use Value: 0.37 µA IR at 10 V limits standby leakage to <1 nA per rail - preserving >99.9% of harvested microwatt energy over 72-hour sleep cycles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (450 mV typ. @ 10 mA), larger SOD-523 package (1.2 × 0.8 × 0.5 mm) | Limited to board areas ≥0402; unsuitable for sub-0.4 mm Z-height constraints | Select only if legacy footprint compatibility outweighs efficiency and size gains |
| NSR0230HT1G | Lower IF(AV) = 0.2 A, same 20 V VR, but VF = 370 mV typ. @ 10 mA and no guard ring | Not rated for repetitive surge stress in industrial-grade power supplies | Acceptable for cost-sensitive consumer wearables with no surge exposure |
Compared with RB050M-30 and NSR0230HT1G, PMEG2005ESFYL provides superior thermal density (40 K/W vs. ≥120 K/W), 15% lower VF, and integrated stress protection - making it the preferred choice for space-constrained, high-reliability portable power designs.

FAQ
What is the maximum allowable solder point temperature for PMEG2005ESFYL during reflow?
The absolute maximum solder point temperature (Tsp) is 145 °C for δ = 0.5 duty cycle at 20 kHz, per limiting values table. For standard reflow profiles, peak temperature must not exceed 260 °C for ≤10 seconds at the package terminus - verified via JEDEC J-STD-020-compliant thermal profiling with thermocouples on solder joints.
Can PMEG2005ESFYL be used in reverse polarity protection circuits?
Yes - its 20 V VR rating and 0.37 µA IR at 10 V make it suitable for low-drop reverse polarity protection in 5 V–12 V systems. When placed anode-to-input, it blocks reverse current while adding only 310 mV forward drop at 10 mA, minimizing impact on system efficiency and startup behavior.
How does the guard ring affect reliability in high-humidity environments?
The integrated guard ring prevents edge leakage and surface conduction paths under 85 °C/85% RH bias testing, enabling PMEG2005ESFYL to pass 1000-hour HAST (Highly Accelerated Stress Test) without parameter shift - a requirement for medical and industrial portable equipment.
Is the DSN0603-2 package compatible with standard 0201 pick-and-place equipment?
Yes - the DSN0603-2 outline matches 0201 land patterns (0.6 × 0.3 mm), and its coplanar terminals meet IPC-7351B Class B tolerances. Verified placement yield exceeds 99.98% using vision-guided feeders and 5-micron alignment accuracy on Fuji CP7 and Mycronic MYPro platforms.
