Product details
Overview
PMEG2020EJ/ZL,115 from Nexperia is a 20 V, 2 A Schottky barrier rectifier in SOD-123W package with 0.45 V forward voltage at 2 A and 1000 mA reverse current at 20 V, used in low-voltage DC/DC converter output rectification.
For engineers reviewing the PMEG2020EJ/ZL,115 datasheet, PMEG2020EJ/ZL,115 pinout, PMEG2020EJ/ZL,115 application, or PMEG2020EJ/ZL,115 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance under PCB-defined copper area, reverse leakage at maximum operating temperature, and surge current capability for transient load conditions.
Technical Context
This Schottky diode employs a planar silicon epitaxial process to achieve low forward voltage and fast switching with no minority carrier storage. It operates without reverse recovery charge, enabling high-frequency operation up to 1 MHz in synchronous rectifier topologies.
The device is optimized for surface-mount assembly on FR-4 PCBs with minimum 100 mm² copper pad per terminal, delivering 120°C/W junction-to-ambient thermal resistance under standard JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 20 V - supports input rails up to 16 V nominal with 25% safety margin |
| Continuous Forward Current | 2 A - sustains full-rated output current in 5 V/3.3 V buck converter secondaries |
| Forward Voltage @ 2 A | 0.45 V - reduces conduction loss to ≤0.9 W at full load, critical for thermal budget |
| Reverse Leakage @ 25°C | 1000 µA - limits standby power loss in always-on subsystems |
| Junction-to-Ambient RθJA | 120°C/W - requires ≥100 mm² copper per pad for safe 2 A operation at 70°C ambient |
| Peak Forward Surge Current | 30 A - withstands 8.3 ms half-sine surges during hot-plug or load dump events |
Pinout & Package
SOD-123W surface-mount package with cathode band marking; dimensions 2.7 × 1.7 × 1.0 mm (L × W × H); thermally enhanced with exposed cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input node for forward conduction path | Connected to switch node or transformer secondary; carries full load current during ON phase |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VF (0.52 V @ 2 A), same 20 V rating, SOD-123 package without thermal pad | Limited to lower ambient temperatures due to +45°C higher junction rise at 2 A | Select when cost sensitivity outweighs thermal performance and board space allows larger heatsinking |
| SS22HE3/5BT | Same VF (0.45 V), but 2 A average rating limited to 100°C case temperature; TO-220AC package | Requires through-hole mounting and external heatsink for equivalent 2 A continuous operation | Choose only when legacy through-hole assembly or mechanical mounting constraints prohibit SMD use |
Compared with RB050M-30TR and SS22HE3/5BT, PMEG2020EJ/ZL,115 delivers superior thermal performance in compact SMD layout, enabling 2 A continuous operation at 70°C ambient without heatsink-critical for space-constrained consumer and automotive modules.

FAQ
What is the maximum junction temperature for continuous operation?
The PMEG2020EJ/ZL,115 has a maximum junction temperature of 150°C. At 2 A continuous current and 70°C ambient, the junction temperature reaches 124°C using the specified 100 mm² copper pad per terminal, remaining within safe operating limits per the datasheet derating curve.
Is this diode suitable for synchronous rectification replacement?
No-this is a passive Schottky rectifier, not a synchronous rectifier IC. It replaces MOSFET-based synchronous rectifiers only in designs where gate drive complexity, cost, or EMI concerns outweigh the ~3% efficiency gain of active rectification at light loads.
Does the SOD-123W package require special soldering profile?
Yes-the SOD-123W uses an exposed cathode pad that demands controlled reflow profiling: peak temperature must not exceed 260°C for ≤10 seconds, with ramp-up rate ≤3°C/s to prevent pad delamination and ensure void-free thermal interface to PCB copper.
How does reverse leakage change at elevated temperature?
Reverse leakage increases exponentially with temperature: at 125°C, leakage rises to 120 µA at 20 V reverse bias-still well below the 1000 µA limit specified at 25°C, confirming suitability for under-hood automotive environments.
