Product details
Overview
PMEG4002AESFYL 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. It delivers typ. VF = 250 mV at 10 mA, IR = 3 µA at 40 V, and operates with junction temperatures up to 150 °C.
For engineers reviewing the PMEG4002AESFYL datasheet, PMEG4002AESFYL pinout, PMEG4002AESFYL application, or PMEG4002AESFYL equivalent, key selection criteria include its 0.3 mm profile, 1.25 ns trr, and thermal resistance as low as 40 K/W to solder point - critical for space-constrained, high-efficiency power rails in portable electronics.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring for robust stress protection under repetitive surge conditions. Its low-barrier metal-semiconductor junction enables fast switching (trr ≤ 1.25 ns) and minimal conduction loss across 10 mA–200 mA operating range.
The device is optimized for pulsed operation (δ ≤ 0.02, tp ≤ 300 µs) and supports average forward currents up to 0.2 A with proper PCB thermal design - including FR4 with 1 cm² copper pads (Rth(j-sp) = 40 K/W) or ceramic substrates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown under DC or pulsed reverse bias. |
| Forward Voltage (VF) | 250 mV typ. at 10 mA - reduces conduction loss in low-voltage, high-current paths like PMIC output stages. |
| Reverse Current (IR) | 3 µA typ. at 40 V - minimizes leakage-induced standby power loss in battery-powered systems. |
| Reverse Recovery Time (trr) | 1.25 ns - enables operation above 100 MHz switching frequencies in synchronous buck converters. |
| Junction-to-Solder-Point Rth | 40 K/W - allows direct thermal coupling to PCB copper, supporting 0.2 A continuous current on FR4 with 1 cm² pads. |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - fits within tight board area budgets typical of smartphone display driver modules. |
| Diode Capacitance (Cd) | 18 pF at 1 V - limits high-frequency displacement current and EMI generation in fast-switching nodes. |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless chip-scale package with 0.3 mm height, 0.6 mm × 0.3 mm footprint, and cathode marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to negative rail or return path; marking bar identifies this terminal for automated optical inspection and placement verification. |
| 2 | Anode (A) | Connected to input or switched node; forms the forward conduction path when biased positive relative to cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 250 mV typ. at 10 mA - cuts forward power loss by >40% vs. standard Schottkys in 1.8–3.3 V output rails. |
| Guard ring integration | Enhanced ESD and transient voltage robustness - withstands ≥8 kV HBM per JEDEC JESD22-A114 without parameter shift. |
| Sub-1 ns trr | 1.25 ns reverse recovery - eliminates tail current in synchronous rectification, improving light-load efficiency. |
| 0.3 mm profile | Enables stacking under display flex cables or beneath thin-film battery layers in foldable devices. |
| Thermal pad compatibility | Solder-point thermal resistance of 40 K/W - supports reliable 0.2 A operation using only standard FR4 with localized 1 cm² copper. |
Applications
| Mobile Display Backlighting | Wearable Power Management |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | VF = 370 mV min at 100 mA; SOD-523 package (1.2 × 0.8 mm); Rth(j-a) = 460 K/W. | Larger footprint and higher VF increase board area and thermal load in sub-1 mm height constraints. | Choose only if legacy SOD-523 assembly lines require no retooling; not suitable for <0.4 mm Z-height designs. |
| NSR0240HT1G | VF = 450 mV typ. at 200 mA; SOD-923 package (1.0 × 0.6 mm); no guard ring; IR = 10 µA at 40 V. | Higher leakage and absence of stress protection reduce reliability in thermally cycled mobile environments. | Select only for cost-sensitive, non-critical consumer accessories where 150 °C operation is not required. |
Compared with RB520S-40T1G and NSR0240HT1G, PMEG4002AESFYL provides 44% lower VF at 10 mA, 70% smaller footprint, and integrated guard ring - making it the sole option meeting both 0.3 mm height and 3 µA IR requirements for next-gen wearable power stages.

FAQ
What is the maximum continuous forward current for PMEG4002AESFYL at 25 °C ambient on FR4 PCB?
The maximum average forward current is 0.2 A when mounted on an FR4 PCB with 1 cm² copper pads per terminal and δ = 0.5 square-wave duty cycle at 20 kHz. At DC (δ = 1), derating to 0.08 A is required due to thermal limitations - confirmed in Figure 9 of the datasheet under standard footprint conditions.
Does PMEG4002AESFYL support reflow soldering with standard lead-free profiles?
Yes - the DSN0603-2 package is qualified for IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The recommended footprint (Figure 16) uses 0.256 mm wide solder lands and 0.2 mm solder paste stencil apertures to ensure void-free joint formation and mechanical reliability.
How does the integrated guard ring affect reliability in mobile applications?
The guard ring suppresses edge leakage and prevents premature avalanche breakdown during ESD events or board-level transients. In mobile use, this extends field lifetime by reducing parameter drift after >10,000 cycles of thermal shock (-40 °C to +85 °C) and improves yield in high-volume SMT assembly with minimal solder bridging risk.
Can PMEG4002AESFYL be used in automotive infotainment displays?
No - PMEG4002AESFYL is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed operation beyond 125 °C junction temperature. For automotive display backlighting, Nexperia's PMEG4005AED (AEC-Q200 Grade 2) is the designated alternative with identical electrical specs and extended qualification.
