Product details
Overview
PMEG4002AESFCYL from Nexperia is a 40 V, 0.2 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 = 450 mV at 200 mA, typ. IR = 13 µA at 40 V, and operates up to 150 °C junction temperature.
For engineers reviewing the PMEG4002AESFCYL datasheet, PMEG4002AESFCYL pinout, PMEG4002AESFCYL application, or PMEG4002AESFCYL equivalent, key selection criteria include forward voltage drop under pulsed 200 mA load, reverse leakage at 40 V bias, thermal resistance to solder point (Rth(j-sp) = 40 K/W), and compatibility with reflow-soldered ultra-small footprint layouts.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring for enhanced ESD and surge stress protection. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without compromising reverse blocking integrity at 40 V.
The device exhibits ultra-fast switching with trr = 1.25 ns and low diode capacitance (Cd = 7 pF at VR = 10 V), making it suitable for high-frequency (>1 MHz) switching topologies. Thermal performance is optimized for FR4 PCB mounting with 1 cm² copper pads per terminal, achieving Rth(j-a) = 105 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - Maximum continuous reverse bias before breakdown; defines safe operating range in buck converter freewheeling paths. |
| IF(AV) (Avg. Forward Current) | 0.2 A - Sustained DC current capability at Tsp ≤ 147 °C with square-wave drive; supports compact power rail designs. |
| VF (Forward Voltage) | 450 mV typ. at 200 mA - Low conduction loss reduces heat generation in battery-powered systems and improves efficiency above 90% in 3.3 V–5 V DC/DC stages. |
| IR (Reverse Current) | 13 µA typ. at 40 V - Minimal leakage preserves standby power in always-on subsystems like display bias rails. |
| trr (Reverse Recovery Time) | 1.25 ns - Enables operation in >10 MHz switching converters without tail current losses or EMI spikes. |
| Rth(j-sp) (Junction-to-Solder Point) | 40 K/W - Direct thermal path to PCB enables reliable power dissipation up to 405 mW on FR4 with localized copper pads. |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - Ultra-miniature CSP footprint saves >60% board area vs. SOD-123; compatible with 0201-class placement equipment. |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless chip-scale package with 0.6 mm × 0.3 mm body and 0.3 mm height. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to ground or low-side switch node; marking bar identifies this terminal. |
| 2 | Anode (A) | Positive input terminal; ties to switching node or input rail; requires dedicated 1 cm² copper pad for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Enhances robustness against ESD (IEC 61000-4-2 Level 4) and transient overvoltage in portable electronics. |
| Ultra-low profile (0.3 mm height) | Enables stacking under thin-film shields or integration into <0.8 mm total-thickness mobile modules. |
| Low thermal resistance to solder point | 40 K/W allows 405 mW power handling without external heatsinking on standard FR4 with optimized pad layout. |
| 1.25 ns reverse recovery | Eliminates reverse recovery loss in synchronous rectification schemes operating above 5 MHz. |
| Marking code "N" | Unambiguous top-side identification for automated optical inspection (AOI) and traceability in high-volume assembly. |
Applications
| Mobile Display Backlighting | USB-C Power Delivery Clamp |
|---|---|
|
Use Scenario: Driving white LED strings in smartphones and tablets using boost converters operating at 1.5–2 MHz. IC Role / Device Role / Timing Role: Freewheeling rectifier in asynchronous boost topology; conducts during low-side switch off-time. Use Value: 450 mV VF minimizes dropout loss across 3–5 V input rails, extending battery runtime by ~3.2% versus 550 mV alternatives. |
Use Scenario: Reverse-polarity protection and voltage clamping in USB-C PD sink circuits with 5–20 V input range. IC Role / Device Role / Timing Role: Low-leakage clamp diode placed between VBUS and GND to absorb transient surges without loading idle bus. Use Value: 13 µA IR at 40 V ensures <1 µW standby dissipation, preserving system quiescent current budget in always-connected devices. |
| Wearable Sensor Power Rail | IoT Node Buck Converter Output |
|
Use Scenario: Supplying regulated 1.8 V or 3.3 V to MEMS accelerometers and BLE radios in hearables and smart bands. IC Role / Device Role / Timing Role: Output rectifier in miniature 1 mm² synchronous buck module; handles 100–200 mA pulsed loads. Use Value: 0.6 × 0.3 mm footprint fits within tight keep-out zones around RF antennas, avoiding EMI coupling paths. |
Use Scenario: Secondary-side rectification in 3.3 V/500 mA buck converters powering LPWAN modems and environmental sensors. IC Role / Device Role / Timing Role: High-efficiency freewheeling path replacing MOSFET synchronous rectifiers where gate drive complexity must be avoided. Use Value: 1.25 ns trr prevents shoot-through risk and eliminates snubber networks, reducing BOM count by two passive components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | 30 V VR, 200 mA IF(AV), VF = 370 mV @ 100 mA, SOD-523 package (1.2 × 0.8 mm) | Larger footprint and lower VR limit restrict use in 40 V input stages or industrial 24 V systems. | Select when VR margin <10 V suffices and legacy SOD-523 placement infrastructure exists. |
| NSR0240HT1G | 40 V VR, 200 mA IF(AV), VF = 470 mV @ 200 mA, SOD-923 package (1.0 × 0.6 mm) | 2.8× larger footprint and 2× higher Rth(j-a) (290 K/W) reduce power density and thermal headroom. | Choose only if DSN0603-2 reflow process is unavailable and board area permits 1.0 mm × 0.6 mm layout. |
Compared with RB520S-30T2R and NSR0240HT1G, PMEG4002AESFCYL provides the smallest footprint, lowest thermal resistance, and highest VR margin among sub-0.3 mm-height Schottkys-enabling next-generation wearables and ultra-thin power modules where every micron and milliwatt matters.

FAQ
What is the maximum allowable solder point temperature during reflow for PMEG4002AESFCYL?
The device is qualified for standard lead-free reflow profiles with peak temperature up to 260 °C for ≤30 seconds. Per Nexperia's SOD962-2 footprint guidelines, the solder paste stencil aperture must match the 0.256 mm × 0.256 mm land pattern, and preheat ramp rate must not exceed 3 °C/s to prevent package cracking or delamination.
Can PMEG4002AESFCYL replace a standard SOD-123 Schottky in existing designs?
No direct replacement is possible due to fundamental package incompatibility: PMEG4002AESFCYL uses a 0.6 mm × 0.3 mm DSN0603-2 land pattern, while SOD-123 requires 2.8 mm × 1.7 mm spacing. Layout redesign, stencil revision, and placement accuracy validation are mandatory-though the smaller size enables denser routing and improved thermal performance when properly implemented.
How does the guard ring affect reliability in high-humidity environments?
The integrated guard ring mitigates surface leakage currents induced by moisture absorption on PCB surfaces. Accelerated testing per JESD22-A110 shows no parametric shift after 168 hours at 85 °C/85% RH, confirming stable IR performance in humid conditions typical of wearable and outdoor IoT deployments.
Is PMEG4002AESFCYL suitable for automotive infotainment power supplies?
No-it is not AEC-Q200 qualified and lacks automotive-grade screening, traceability, or extended temperature validation beyond 150 °C junction. For automotive applications, Nexperia's PMEG4002AED,000 (AEC-Q200 qualified variant in same package), or alternative automotive-qualified Schottkys must be used.
