Product details
Overview
PMEG10020AELRX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 100 V reverse voltage and 2 A average forward current, featuring 710 mV forward voltage at 2 A and only 70 nA reverse leakage at 100 V and 25 °C - deployed in low-voltage DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG10020AELRX datasheet, PMEG10020AELRX pinout, PMEG10020AELRX application, or PMEG10020AELRX equivalent, key selection criteria include ultra-low leakage current, high-temperature operation up to 175 °C junction, clip-bonded thermal performance, and SOD123W package compatibility with space-constrained power rails.
Technical Context
This Schottky diode uses a planar silicon die with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF (710 mV typ. @ 2 A) and extremely low IR (70 nA @ 100 V, 25 °C) stem from optimized metal–semiconductor interface and shallow junction design.
Thermal performance is enhanced via clip-bonding technology, delivering Rth(j-sp) as low as 18 K/W to the cathode solder point and enabling sustained 2 A conduction at Tsp ≤ 160 °C on standard FR4 PCBs. Reverse recovery time is negligible (<5 ns), confirming true majority-carrier operation without minority-carrier storage delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports input stages in 48 V industrial systems and PoE-powered devices without derating. |
| Average Forward Current (IF(AV)) | 2 A - delivers continuous output in compact 5–12 V DC-DC modules with minimal heatsinking. |
| Forward Voltage (VF) | 710 mV @ 2 A, 25 °C - reduces conduction loss by ~30% vs. comparable 100 V Schottkys with VF > 900 mV. |
| Reverse Leakage (IR) | 70 nA @ 100 V, 25 °C - enables battery-backed circuits to retain charge for >10 years without significant drain. |
| Junction Temperature (Tj) | 175 °C max - allows operation in sealed enclosures or near heat sources without thermal shutdown. |
| Package | SOD123W (CFP3) - 2.6 mm × 1.7 mm × 1.0 mm footprint with flat leads for low-profile reflow assembly. |
| Reverse Recovery Time (trr) | <5 ns - eliminates switching tail current in high-frequency (>500 kHz) synchronous rectifiers. |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount plastic package: 2-terminal, small-outline, flat-lead design measuring 2.6 mm × 1.7 mm × 1.0 mm with cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for rectified current; marked by bar; connects to ground or return path in buck/flyback outputs. |
| 2 | Anode (A) | Input node for unidirectional current flow; ties to switch node or AC input in bridgeless configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under voltage transients, improving surge robustness in automotive and industrial environments. |
| Clip-bonding construction | Reduces thermal resistance to solder point by 40% vs. wire-bonded equivalents, enabling higher current density in same footprint. |
| Ultra-low IR at high VR | 300 nA max @ 100 V, 25 °C ensures <1 µW reverse power dissipation - critical for energy-harvesting and battery-life-sensitive designs. |
| High-temperature capability | Rated for continuous operation at Tj = 175 °C, supporting placement near MOSFETs or in thermally dense power stages. |
| SOD123W package | Enables automated placement and reflow at IPC Class 3 standards; compatible with 0.1 mm stencil thickness for precise solder paste control. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Secondary-side rectification in 5 V/3 A isolated flyback converter powering FPGA I/O banks. IC Role / Device Role / Timing Role: Unidirectional current valve conducting during transformer reset phase; no timing control required. Use Value: 710 mV VF minimizes conduction loss to <1.5 W, reducing thermal load on compact PCB layout. |
Use Scenario: Input protection for USB-C PD sink circuit exposed to accidental reverse connection. IC Role / Device Role / Timing Role: Series-blocking element placed between connector and LDO input; conducts only when polarity is correct. Use Value: 70 nA leakage prevents measurable battery drain during standby, preserving >99% charge over 12 months. |
| Low-Voltage AC/DC Adapter | High-Efficiency Buck Converter Freewheeling Diode |
|
Use Scenario: Output rectifier in 12 V/1.5 A wall adapter using quasi-resonant topology. IC Role / Device Role / Timing Role: Conducts during secondary winding demagnetization; handles peak currents up to 30 A repetitive. Use Value: 5 ns trr avoids reverse recovery losses, sustaining >92% efficiency at full load across line and load variation. |
Use Scenario: Freewheeling path in 3.3 V/2 A buck regulator driving SSD controller logic rails. IC Role / Device Role / Timing Role: Provides low-loss current path during high-side MOSFET off-time; operates at 1 MHz switching frequency. Use Value: Clip-bonded thermal path maintains Tj < 125 °C even with 2 A RMS current and minimal copper area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSSAF210-M3/5AT | Same 100 V VR, 2 A IF(AV), but VF = 750 mV min @ 2 A; IR = 100 nA @ 100 V, 25 °C. | Higher VF increases conduction loss by ~80 mW at 2 A; suitable where leakage tolerance >100 nA. | Select if cost sensitivity outweighs 40 mV VF advantage and board-level thermal margin exceeds 5 °C. |
| ON Semiconductor SB2100 | 100 V VR, 2 A IF(AV), VF = 800 mV typ @ 2 A; IR = 500 nA @ 100 V, 25 °C; TO-277 package (larger than SOD123W). | Higher leakage degrades battery retention; TO-277 requires 3× more PCB area and limits high-density layouts. | Choose only when legacy TO-277 footprint reuse is mandatory and thermal budget permits +120 mV VF penalty. |
Compared with VSSAF210-M3/5AT and SB2100, PMEG10020AELRX offers the lowest combined VF/IR trade-off in SOD123W, enabling smaller thermal solutions and longer battery hold-up in portable and sealed-system designs.

FAQ
What is the maximum allowable solder point temperature for PMEG10020AELRX during reflow?
The datasheet specifies a maximum solder point temperature (Tsp) of 160 °C for continuous 2 A operation under δ = 0.5 square-wave conditions. For reflow, peak profile must not exceed 260 °C for ≤10 seconds per JEDEC J-STD-020, with ramp rates compliant for SOD123W package integrity.
Does PMEG10020AELRX have automotive qualification?
No. Per Nexperia's revision history (v.5, Jan 2023), this part is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and is not recommended for safety-critical or engine-compartment applications. Automotive alternatives carry "-Q" suffixes and require separate validation.
How does the guard ring affect voltage derating in high-humidity environments?
The integrated guard ring mitigates surface leakage paths along the die edge, maintaining VR stability under 85% RH/85 °C bias conditions. Test data shows no measurable IR increase after 1000 hours of damp heat, unlike non-guard-ring Schottkys that exhibit >10× IR drift.
Can PMEG10020AELRX replace a standard 1N5819 in existing designs?
Yes - with caveats. It matches 1N5819's 100 V/1 A rating but exceeds it in current (2 A avg), leakage (70 nA vs. ~1 µA), and thermal capability. However, its SOD123W footprint differs from DO-214AC (SMA); mechanical redesign is required unless using compatible adapter footprints.
