Product details
Overview
PMEG2020EJ/ZLX from Nexperia is a 20 V, 2 A Schottky barrier rectifier in SOD-123W package with 0.45 V forward voltage at 2 A, 1000 mA reverse current at 20 V, and 25 ns reverse recovery time - used in low-voltage DC/DC converter output rectification.
For engineers reviewing the PMEG2020EJ/ZLX datasheet, PMEG2020EJ/ZLX pinout, PMEG2020EJ/ZLX application, or PMEG2020EJ/ZLX equivalent, key selection criteria include VF vs. IF performance at 85°C, thermal resistance (Rthj-a = 170 K/W), and SOD-123W footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a planar silicon epitaxial process to achieve low forward voltage drop and fast switching behavior without minority carrier storage delay. Its unidirectional configuration supports continuous forward conduction and blocks reverse voltage up to 20 V.
Thermal design relies on the SOD-123W package's exposed cathode pad for enhanced heat dissipation. The device operates within -65 °C to +150 °C junction temperature range and meets AEC-Q101 stress test requirements for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 20 V - defines maximum blocking capability in flyback or freewheeling paths |
| Forward Current (IF) | 2 A continuous - supports sustained load current in compact power rails |
| Forward Voltage (VF) | 0.45 V at IF = 2 A, TJ = 25 °C - reduces conduction loss in 3.3 V/5 V output stages |
| Reverse Recovery Time | 25 ns - enables operation in 1–3 MHz switching converters without tail current penalty |
| Junction Temp Range | -65 °C to +150 °C - qualifies for under-hood automotive and industrial ambient conditions |
| Thermal Resistance | Rthj-a = 170 K/W - determines derating curve when mounted on 100 mm² 1 oz Cu pad |
Pinout & Package
SOD-123W surface-mount package with molded epoxy body, gull-wing leads, and exposed cathode thermal pad on underside. Dimensions: 2.7 × 1.5 × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to higher-potential node (e.g., switch node in buck converter) |
| Cathode (K) | Forward current exit / reverse blocking terminal | Connected to output rail; thermal pad tied to ground plane for heat transfer |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high IF | 0.45 V @ 2 A enables >92% efficiency in 5 V → 3.3 V buck output stage |
| AEC-Q101 qualified | Passed stress tests including HTGB, TC, AC/HAST - suitable for automotive infotainment power supplies |
| Fast switching | 25 ns trr eliminates reverse recovery loss in MHz-range synchronous rectifiers |
| SOD-123W thermal pad | Exposed cathode pad lowers Rthj-a by 35% vs. standard SOD-123, enabling 1.5× higher power density |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 30 V VR, 0.2 A IF, SOD-523 package, VF = 0.33 V @ 0.1 A | Limited to sub-500 mA loads; unsuitable for 2 A output stages | Select only for ultra-compact, low-current bias rails where space is critical and current ≤ 0.2 A |
| SS22HE3/5BT | 20 V VR, 2 A IF, SMA package, VF = 0.5 V @ 2 A, Rthj-a = 200 K/W | Larger footprint, higher thermal resistance, no AEC-Q101 qualification | Acceptable for cost-sensitive industrial designs where automotive qualification and thermal performance are not required |
Compared with RB520S-30T1G and SS22HE3/5BT, PMEG2020EJ/ZLX uniquely balances 2 A current capability, 0.45 V VF, AEC-Q101 compliance, and SOD-123W thermal efficiency - making it optimal for space-constrained, thermally demanding automotive and industrial DC/DC outputs.

FAQ
What is the maximum junction temperature for continuous operation?
The PMEG2020EJ/ZLX has a maximum junction temperature of +150 °C. Derating begins at +125 °C ambient when mounted on a standard 100 mm² 1 oz copper pad. At 2 A DC current and 85 °C ambient, measured TJ reaches approximately 115 °C, staying within safe operating limits per datasheet thermal curves.
Is this diode suitable for synchronous rectification replacement?
No - PMEG2020EJ/ZLX is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a freewheeling or output rectifier in non-synchronous topologies. For synchronous rectification, a dedicated gate driver IC paired with a low-RDS(on) MOSFET is required.
Does the SOD-123W package require special soldering profile?
Yes - the exposed cathode pad requires controlled reflow profiling: peak temperature 260 °C max, time above 217 °C ≤ 60 seconds, and ramp-up rate ≤ 3 °C/s. Insufficient pad thermal mass or excessive dwell time risks delamination; IPC-J-STD-020D-compliant profiles are recommended.
How does reverse leakage compare at elevated temperature?
At 125 °C junction temperature and 20 V reverse bias, IR increases to 120 µA - still well below the 1000 µA limit specified at 25 °C. This low drift ensures stable performance in hot environments like automotive engine compartments or enclosed industrial enclosures.
