Product details
Overview
PMEG2002AESFBYL from Nexperia is a 20 V, 0.2 A planar MEGA Schottky barrier rectifier in an ultra-small DSN0603B-2 (SOD962B) leadless SMD package, featuring 375 mV typical forward voltage at 200 mA, ≤45 µA reverse leakage at 20 V, and 1.9 ns reverse recovery time - deployed in mobile LED backlighting and low-power DC-DC converters.
For engineers reviewing the PMEG2002AESFBYL datasheet, PMEG2002AESFBYL pinout, PMEG2002AESFBYL application, or PMEG2002AESFBYL equivalent, key selection criteria include ultra-low VF for efficiency-critical 1–3 V rail rectification, thermal resistance to solder point (190 K/W), 0.2 mm profile for space-constrained PCBs, and cathode-marked terminal identification for automated assembly verification.
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 minority-carrier storage, delivering sub-2 ns trr and eliminating reverse recovery tail current.
Designed for high-frequency switching up to several MHz, it operates with junction temperatures up to 125 °C and supports pulsed forward currents up to 4 A (8 ms). Thermal performance is specified for two PCB mounting conditions: standard footprint (310 K/W Rth(j-a)) and enhanced pad layout (40 K/W Rth(j-sp)).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 200 mA | 375–420 mV - Enables ≥92% efficiency in 1.8 V buck converter output rectification |
| VR | 20 V - Rated for use in 12 V and lower input rails with margin against transients |
| IR @ 20 V | 10–45 µA - Low leakage preserves battery life in always-on smartcard and IoT standby modes |
| trr | 1.9 ns - Supports >100 MHz switching without reverse recovery loss penalty |
| Cd @ 10 V | 10 pF - Minimizes capacitive loading on high-speed gate-drive or RF bias networks |
| Rth(j-sp) | 190 K/W - Requires ≥1 cm² copper pad per terminal for sustained 0.2 A DC operation |
| Package size | 0.6 × 0.3 × 0.2 mm - Fits 0201-class footprints; compatible with 0.4 mm pitch reflow processes |
Pinout & Package
DSN0603B-2 (SOD962B) is a 2-terminal, leadless, ultra-thin surface-mount package with 0.4 mm pitch and transparent top marking. The cathode is identified by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to load/ground side; marked by bar; carries forward current out of device |
| 2 | Anode (A) | Connected to source/rail side; unmarked terminal; accepts forward current into device |
Key Features
| Feature | Design Value |
|---|---|
| Low VF Schottky architecture | 375 mV typ. at 200 mA enables <0.075 W conduction loss in 1.8 V/200 mA rail |
| Guard ring integration | Improves ruggedness against ESD (IEC61000-4-2 Level 4) and line transients in portable systems |
| Ultra-thin 0.2 mm profile | Permits stacking under connectors or beneath thin-film shields in slim mobile designs |
| Leadless SMD construction | Eliminates solder wicking risk and improves coplanarity yield in fine-pitch automated assembly |
| Low Cd (10 pF @ 10 V) | Reduces high-frequency AC coupling in RF bias paths and fast-switching gate drive snubbers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | 30 V VR, 200 mA IF(AV), VF = 370 mV @ 100 mA, SOD-523 package (0.6 × 0.3 × 0.5 mm) | Higher VR margin but 2.5× taller (0.5 mm vs. 0.2 mm); unsuitable for ultra-thin assemblies | Select when 30 V rating is mandatory and height constraint is relaxed. |
| NSR0230HT1G | 30 V VR, 200 mA IF(AV), VF = 450 mV @ 200 mA, SOD-923 package (1.0 × 0.6 × 0.4 mm) | Higher VF increases conduction loss by ~20%; larger footprint limits density in wearables | Select only if legacy SOD-923 footprint compatibility is required. |
Compared with RB521S-30T2R and NSR0230HT1G, PMEG2002AESFBYL delivers the lowest profile (0.2 mm) and best VF efficiency (375 mV) within its 20 V class, making it optimal for thickness- and efficiency-critical portable power rails where VR margin is sufficient.

FAQ
What is the maximum continuous forward current for PMEG2002AESFBYL at 85 °C ambient?
At Tamb = 85 °C on a standard FR4 PCB (single-sided copper, tin-plated), the maximum average forward current is 0.12 A for δ = 0.5 duty cycle and 20 kHz square wave, per Figure 8. Derating is required above 25 °C ambient due to thermal resistance of 310 K/W.
Does PMEG2002AESFBYL have automotive qualification?
No. PMEG2002AESFBYL is not AEC-Q200 qualified and is intended for consumer and industrial applications only. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or automotive use without additional customer validation.
How is cathode identification implemented on the DSN0603B-2 package?
The cathode is marked by a visible bar on the top surface of the device, aligned with terminal 1 per Table 2. This marking is laser-etched and remains legible after reflow; no polarity silkscreen is required on the PCB for automated optical inspection.
Can PMEG2002AESFBYL be used in place of a silicon PN diode in a 5 V supply rail?
Yes - with caution. Its 20 V VR rating provides margin, but its 375 mV VF yields significantly lower conduction loss than a typical 700 mV silicon diode. However, its higher IR (up to 45 µA) may affect ultra-low-power sleep modes where leakage must be <1 µA.
