Product details
Overview
PMEG2002ESF from Nexperia is a 20 V, 0.2 A planar MEGA Schottky barrier rectifier in an ultra-small DSN0603-2 (SOD962-2) leadless SMD package, featuring typ. 435 mV forward voltage at 200 mA, 0.88 µA reverse current at 20 V, and 1.9 ns reverse recovery time - optimized for low-voltage, high-efficiency DC-to-DC conversion in space-constrained mobile power rails.
For engineers reviewing the PMEG2002ESF datasheet, PMEG2002ESF pinout, PMEG2002ESF application, or PMEG2002ESF equivalent, key selection criteria include its ultra-low VF for minimal conduction loss, sub-0.3 mm profile for thin-profile designs, and integrated guard ring for robust ESD and surge stress protection in battery-powered systems.
Technical Context
This Schottky diode employs a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its metal-semiconductor junction enables near-zero minority-carrier storage, delivering 1.9 ns trr and eliminating reverse recovery tail current.
Designed for operation up to 125 °C junction temperature, it supports average forward currents of 0.2 A at Tamb ≤ 115 °C (δ = 0.5, f = 20 kHz), with thermal resistance Rth(j-sp) as low as 40 K/W when soldered to cathode tab - critical for thermally dense PMIC output stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - maximum blocking capability for 12 V and 15 V rail clamping and flyback snubbing |
| Forward Voltage (VF) | 435 mV typ. @ 200 mA - reduces conduction loss by >30% vs. standard Schottkys in 0.2 A load paths |
| Reverse Current (IR) | 0.88 µA typ. @ 20 V - minimizes standby leakage in always-on battery circuits |
| Reverse Recovery Time (trr) | 1.9 ns - enables clean switching in >10 MHz DC-DC converters without ringing or shoot-through risk |
| Package Dimensions | 0.6 × 0.3 × 0.3 mm - fits within 0.7 mm pitch layouts for ultra-compact wearable and IoT PCBs |
| Junction-to-Solder-Point Rth | 40 K/W - enables direct thermal coupling to ground plane via cathode tab for stable 0.2 A continuous operation |
Pinout & Package
DSN0603-2 (SOD962-2) is a 2-terminal, leadless, ultra-thin surface-mount package with 0.6 mm × 0.3 mm body and 0.3 mm height. The marking bar on top identifies Pin 1 as cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to negative output or ground return path; primary heat-sinking terminal |
| 2 | Anode (A) | Connected to input or switching node; minimal parasitic inductance due to short internal trace |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 435 mV typ. @ 200 mA - cuts I²R losses in portable device buck converter outputs |
| Guard ring integration | Edge termination structure - prevents premature avalanche at package periphery under voltage transients |
| Sub-0.3 mm profile | 0.3 mm max height - enables stacking under connectors or beneath display modules in slim smartphones |
| Low capacitance | 9 pF @ 10 V - preserves high-frequency efficiency in MHz-range synchronous rectifiers |
| High surge rating | 4.5 A IFSM (8 ms) - withstands inrush during hot-plug events in USB-C PD power paths |
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 - higher voltage rating but 15% higher VF at 200 mA | Better suited for 24 V industrial inputs; less optimal for 5 V mobile rails due to higher conduction loss | Select when system requires 30 V margin and can accept 65 mV higher VF at full load |
| NSR0230HT1G | 30 V VR, 200 mA IF(AV), VF = 410 mV @ 200 mA, Rth(j-a) = 250 K/W - no guard ring, higher thermal resistance | Lacks integrated stress protection; unsuitable for unregulated input transients in consumer chargers | Prefer only in cost-sensitive, non-transient environments with ample board-level clamping |
Compared with RB521S-30T2R and NSR0230HT1G, PMEG2002ESF delivers the lowest VF at rated current, best thermal performance via cathode-tab solder point, and guaranteed guard-ring protection - making it the optimal choice for miniaturized, battery-critical, and transient-prone DC-DC outputs.

FAQ
What is the maximum continuous forward current for PMEG2002ESF at 85 °C ambient?
At Tamb = 85 °C with δ = 0.5 and f = 20 kHz square wave, PMEG2002ESF supports 0.2 A average forward current on FR4 PCB with standard footprint. Derating is required above this temperature - see Figure 9 for exact IF(AV) vs. Tamb curves.
Does PMEG2002ESF require a heatsink for 0.2 A operation?
No external heatsink is needed. With Rth(j-sp) = 40 K/W and Ptot ≈ 87 mW at 0.2 A/435 mV, junction temperature rise is ~3.5 °C above solder point - well within 125 °C Tj limit even with minimal copper area.
How is polarity identified on the DSN0603-2 package?
A laser-marked bar on the top surface indicates Pin 1 (cathode). The unmarked end is the anode. This matches the simplified outline in Table 2 and Figure 15 of the datasheet, and is visible under 20× magnification.
Can PMEG2002ESF replace a standard 1N5819 in a 5 V buck converter?
Yes - with advantages: 435 mV VF vs. ~450–600 mV for 1N5819 at 200 mA improves efficiency by ~2–3%, and the 0.6 × 0.3 mm DSN0603-2 package saves >80% board area. However, VR = 20 V is lower than 1N5819's 40 V, so verify input transient margins.
