Product details
Overview
PMEG4002ESFCYL from Nexperia is a 40 V, 0.2 A planar MEGA Schottky barrier rectifier in a leadless DSN0603-2 (SOD962-2) chip-scale package, featuring low forward voltage (525 mV typ. at 200 mA), ultra-low reverse current (1.2 µA typ. at 40 V), and 0.3 mm profile - optimized for space-constrained mobile LED backlight and DC-DC converter outputs.
For engineers reviewing the PMEG4002ESFCYL datasheet, PMEG4002ESFCYL pinout, PMEG4002ESFCYL application, or PMEG4002ESFCYL equivalent, key selection criteria include forward voltage drop under pulsed 200 mA load, thermal resistance to solder point (40 K/W), junction temperature limit (150 °C), and compatibility with reflow-soldered ultra-small footprint layouts.
Technical Context
This Schottky diode uses a planar MEGA structure with integrated guard ring for enhanced ESD and surge stress protection. Its metal–semiconductor junction enables near-zero reverse recovery time (1.28 ns) and eliminates minority-carrier storage delay, making it suitable for high-frequency switching above 1 MHz.
The device operates within a −55 °C to 150 °C ambient range and delivers stable performance up to 145 °C solder point temperature. Thermal design relies on low Rth(j-sp) (40 K/W) to anode tab, requiring precise PCB copper pad layout per Figure 16 (0.256 mm × 0.676 mm lands).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown under DC or pulsed conditions at Tj = 25 °C. |
| Forward Voltage (VF) | 525 mV typ. at IF = 200 mA - reduces conduction loss by >30% vs. standard Schottkys in 3.3 V/5 V rail rectification. |
| Reverse Current (IR) | 1.2 µA typ. at VR = 40 V - minimizes standby power leakage in battery-backed systems. |
| Reverse Recovery Time (trr) | 1.28 ns - enables operation in >10 MHz switching converters without tail current losses. |
| Junction Temperature (Tj) | 150 °C max - defines safe continuous operation limit; derating required above 125 °C ambient on FR4. |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - fits 0201-class board area with 0.2 mm pitch, enabling ultra-dense portable PCB layouts. |
| Thermal Resistance (Rth(j-sp)) | 40 K/W - enables direct thermal coupling to PCB copper, critical for maintaining <125 °C junction under 0.2 A DC load. |
Pinout & Package
DSN0603-2 (SOD962-2) is a leadless, surface-mount chip-scale package with two terminals 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) | Connected to negative output rail; marking bar identifies this terminal; requires dedicated thermal pad for heat extraction. |
| 2 | Anode (A) | Connected to input/switching node; solder point serves as primary thermal path (Rth(j-sp) = 40 K/W). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents edge breakdown under transient overvoltage, improving reliability in mobile DC-DC output stages. |
| Ultra-low profile (0.3 mm) | Enables stacking under thin-film shields or beneath display flex cables in smartphone bezel designs. |
| Low capacitance (7 pF at 10 V) | Minimizes high-frequency switching noise coupling in buck converter feedback paths. |
| Pulsed peak current (IFRM) | 1.2 A - supports short-duration inrush or burst-mode loads without thermal runaway. |
| Marking code "M" | Enables automated optical inspection (AOI) traceability on 0201-scale placement lines. |
Applications
| Mobile LED Backlight | USB-C Power Delivery Output Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSKY0240 | Same 40 V/0.2 A rating but VF = 550 mV (25 mV higher); Rth(j-a) = 310 K/W (vs. 105 K/W for PMEG4002ESFCYL on FR4). | Larger SOD-323 package (1.7 × 1.3 mm) increases board area by 7×; unsuitable for <2 mm² layout zones. | Select when legacy footprint compatibility outweighs efficiency and size requirements. |
| ON Semiconductor NSR0240HT1G | VF = 450 mV at 200 mA (75 mV lower), but IR = 5 µA at 40 V (4× higher leakage) and no guard ring. | Lacks integrated stress protection; requires external RC snubber in high-dV/dt SMPS outputs. | Select only for cost-sensitive, non-critical consumer applications where leakage <1 µA is not required. |
Compared with VSKY0240 and NSR0240HT1G, PMEG4002ESFCYL uniquely balances ultra-low VF, guarded junction robustness, and 0201-scale packaging - making it the only option meeting simultaneous requirements for mobile backlight efficiency, wearable battery shelf life, and IoT EMI compliance.

FAQ
What is the maximum allowable solder point temperature during reflow for PMEG4002ESFCYL?
The absolute maximum solder point temperature is 175 °C, as defined in the limiting values table. Peak reflow profile must not exceed this value for more than 30 seconds, and the recommended profile follows IPC-J-STD-020 for MSL1 devices with preheat ramp rate ≤3 °C/s and time above 217 °C limited to 60–90 seconds.
Can PMEG4002ESFCYL be used in automotive applications?
No - PMEG4002ESFCYL is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or extended lifetime testing. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive use.
How does the guard ring improve reliability in PMEG4002ESFCYL?
The integrated guard ring redistributes electric field concentration at the silicon edge, preventing premature avalanche breakdown during transient voltage events such as ESD or load dump. This extends operational lifetime in handheld devices exposed to frequent electrostatic discharge and improves yield in high-frequency switching environments.
What is the minimum recommended PCB copper pad size for thermal performance?
Per Figure 16, the recommended solder land is 0.256 mm × 0.676 mm per terminal, with 0.2 mm spacing. For optimal thermal performance, each pad must connect to ≥1 cm² of 1 oz copper on FR4 - achieving the 105 K/W Rth(j-a) value cited in Table 6 and enabling 0.2 A average current at 70 °C ambient.
