Product details
Overview
PMEG2002AESF,315 from Nexperia is a planar MEGA Schottky barrier rectifier in a DSN0603-2 (SOD962-2) ultra-small leadless SMD package, rated for 20 V reverse voltage and 0.2 A average forward current, with typ. 245 mV forward voltage at 10 mA and 5 µA reverse leakage at 10 V - deployed in mobile LED backlight and low-voltage DC-DC converters.
For engineers reviewing the PMEG2002AESF,315 datasheet, PMEG2002AESF,315 pinout, PMEG2002AESF,315 application, or PMEG2002AESF,315 equivalent, key selection criteria include ultra-low VF for efficiency-critical 1–3 V rail rectification, 0.3 mm profile for space-constrained portable designs, and thermal performance on FR4 vs. ceramic PCBs under pulsed loads.
Technical Context
This Schottky diode uses a planar silicon structure with integrated guard ring for enhanced ESD and surge robustness. Its low-barrier metal-semiconductor junction enables sub-420 mV VF at 200 mA (pulsed), while maintaining IR ≤ 10 µA at VR = 20 V and Tj = 25 °C.
Designed for high-frequency switching (trr < 2 ns), it operates up to 125 °C junction temperature and supports peak forward currents up to 4.5 A (8 ms non-repetitive). Thermal resistance varies significantly with PCB layout: Rth(j-a) ranges from 105 K/W (ceramic) to 310 K/W (standard FR4).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - maximum blocking capability for 12–15 V input rails in compact DC-DC stages |
| Average Forward Current (IF(AV)) | 0.2 A - continuous conduction limit at Tsp ≤ 120 °C on standard FR4 PCB |
| Forward Voltage (VF) | 245 mV typ. at IF = 10 mA - enables >95% efficiency in 1.8 V output buck converters |
| Reverse Current (IR) | 5 µA typ. at VR = 10 V - minimizes standby power loss in battery-powered systems |
| Reverse Recovery Time (trr) | 1.9 ns - supports >10 MHz switching without tail current losses |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - fits 0201-class footprints with 0.25 mm pitch terminals |
| Thermal Resistance (Rth(j-sp)) | 40 K/W - enables direct thermal coupling to solder pad for high-pulse-current handling |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless ultra-small surface-mount package with 0.6 mm × 0.3 mm body and 0.3 mm height; cathode identified by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for forward conduction; connected to lower potential side of load or ground return path |
| 2 | Anode (A) | Input node for forward conduction; ties to switched or unregulated supply rail |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves ESD robustness (HBM > 8 kV) and prevents edge breakdown during voltage transients |
| Ultra-low VF at low current | 120 mV typ. at 0.1 mA enables efficient biasing in sensor signal conditioning paths |
| Low-profile mounting | 0.3 mm max height allows stacking under thin-film shields or beneath display modules |
| High pulse current rating | 4.5 A non-repetitive peak supports inrush current limiting in hot-swap circuits |
| Optimized for FR4 thermal pads | 1 cm² copper per terminal reduces Rth(j-a) to 190 K/W - critical for sustained 0.2 A operation |
Applications
| Mobile LED Backlight | USB-C Power Delivery Clamp |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RBS202ASTB | Same 20 V/0.2 A rating but VF = 320 mV typ. at 10 mA; larger SOD-923 package (1.0 × 0.6 mm) | Less suitable for sub-1 mm height constraints; higher VF increases loss in 1.8 V output stages | Select when board space allows larger footprint and thermal mass improves long-term reliability at 125 °C ambient |
| RB521S-30T2R | 30 V VR rating; VF = 370 mV typ. at 10 mA; same DFN1006 package but no guard ring | Higher VR margin useful in 24 V industrial sensors; lacks stress protection for mobile drop-test environments | Prefer where reverse voltage margin >20 V is required and ESD immunity beyond IEC 61000-4-2 Level 3 is not mandated |
Compared with RBS202ASTB and RB521S-30T2R, PMEG2002AESF,315 delivers the lowest VF in its class and unique guard-ring-enhanced ruggedness - making it optimal for ultra-thin consumer electronics where both efficiency and mechanical shock survival are design-critical.

FAQ
What is the maximum allowable soldering temperature for PMEG2002AESF,315?
The device is qualified for reflow soldering per J-STD-020, with peak temperature of 260 °C for ≤ 30 seconds. The recommended footprint (Fig. 16) specifies 0.256 mm solder land width and 0.676 mm occupied area to ensure void-free joints and mechanical reliability on 0.3 mm-thick substrates.
Can PMEG2002AESF,315 be used in automotive applications?
No - this part is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or extended lifetime testing. Nexperia explicitly states non-automotive qualification in Section 15 of the datasheet; use only in commercial or industrial portable equipment.
How does the guard ring affect layout requirements?
The integrated guard ring requires no special PCB layout but mandates strict adherence to the recommended 0.2 mm clearance between cathode/anode lands and adjacent traces to prevent field crowding. The marking bar must remain fully visible after soldering for post-assembly polarity verification.
What is the minimum recommended copper area per terminal for 0.2 A continuous operation?
For continuous 0.2 A at Tamb = 60 °C, Nexperia specifies ≥ 1 cm² of 1 oz copper per terminal on FR4 (Table 5, Note [3]). Using smaller pads increases Rth(j-a) to 310 K/W, reducing usable current to ≤ 0.1 A without active cooling.
