Product details
Overview
PMEG3005EJ/ZLX from Nexperia is a planar Schottky barrier rectifier in SOD323F (SC-90) package, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 0.5 A forward current, 30 V reverse voltage rating, 380–430 mV forward voltage at 500 mA, 55–70 pF diode capacitance at 1 V, and operates up to 150 °C junction temperature.
For engineers reviewing the PMEG3005EJ/ZLX datasheet, PMEG3005EJ/ZLX pinout, PMEG3005EJ/ZLX application, or PMEG3005EJ/ZLX equivalent, this device is selected for compact power rail protection, ultra-low VF rectification in space-constrained buck converters, and low-loss reverse-battery safeguards in portable electronics.
Technical Context
This Schottky rectifier uses a MEGA (Maximum Efficiency General Application) planar structure with integrated guard ring for enhanced ESD and surge stress resilience. Its low VF and low Cd enable minimal conduction loss and fast switching in high-frequency SMPS topologies.
The device exhibits thermally stable reverse leakage (<150 μA at 30 V, 25 °C) and low thermal resistance (Rth(j-sp) = 55 K/W), supporting reliable operation on standard FR4 PCBs without heatsinking in ambient temperatures up to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 0.5 A continuous - supports sustained output rectification in sub-1 W DC/DC stages |
| Reverse voltage (VR) | 30 V - suitable for 24 V nominal input rails with safety margin against transients |
| Forward voltage (VF) | 380–430 mV @ 500 mA - reduces conduction loss by >40% vs. standard silicon diodes |
| Diode capacitance (Cd) | 55–70 pF @ 1 V, 1 MHz - minimizes switching loss and EMI in >1 MHz converter designs |
| Reverse current (IR) | ≤40 μA @ 30 V, 25 °C - ensures low standby power in battery-backed systems |
| Junction temperature (Tj) | 150 °C max - enables operation in sealed enclosures or high-ambient industrial environments |
| Thermal resistance (Rth(j-sp)) | 55 K/W - allows direct thermal coupling to PCB copper for passive cooling |
Pinout & Package
Encapsulated in SOD323F (JEITA SC-90) surface-mount package: 2.7 mm × 1.6 mm footprint, 0.55 mm height, flat leads optimized for reflow soldering and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to output rail or ground return path; marked with cathode bar on top surface |
| 2 | Anode | Connected to input or switching node; carries full forward current during conduction phase |
Key Features
| Feature | Design Value |
|---|---|
| MEGA planar Schottky architecture | Enables uniform current distribution and reduced hot-spot risk under pulsed loads |
| Integrated guard ring | Improves ruggedness against ESD (IEC 61000-4-2 Level 4) and repetitive voltage surges |
| Ultra-low VF at low IF | 380 mV typ. @ 500 mA - critical for extending battery runtime in wearables and IoT sensors |
| Low-profile SOD323F package | 0.55 mm max height - fits under 0.8 mm board gaps in stacked modules and thin clients |
| Reflow-solder compatible footprint | Optimized pad layout per Fig. 13 (Nexperia DS) - eliminates tombstoning and voiding in volume production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | 0.3 A IF rating, 30 V VR, VF = 370 mV @ 300 mA, SOD-523 package (1.6 × 0.8 mm) | Lower current capacity and smaller footprint - suited only for ≤300 mA loads | Select when board area is constrained below 2.7 × 1.6 mm and peak load stays under 0.3 A |
| SS32 | 3 A IF rating, 20 V VR, VF = 500 mV @ 3 A, SMA package (4.5 × 2.7 mm) | Higher current but larger size and higher VF - requires thermal relief and more PCB area | Select when system demands >0.5 A continuous current and 20 V VR suffices |
Compared with RB520S-30T2R and SS32, PMEG3005EJ/ZLX uniquely balances 0.5 A capability, 30 V rating, ultra-low VF, and ultra-compact SOD323F packaging - making it optimal for space-limited, efficiency-critical 24 V input DC/DC stages.

FAQ
What is the maximum allowable junction temperature for PMEG3005EJ/ZLX?
The absolute maximum junction temperature is 150 °C, as defined in IEC 60134 limiting values. Operation at this temperature requires derating of forward current per the thermal curves in Figure 4 of the datasheet, and proper PCB copper area (≥1 cm² cathode pad) to maintain Rth(j-sp) ≤55 K/W.
Is PMEG3005EJ/ZLX suitable for use in automotive applications?
PMEG3005EJ/ZLX is not AEC-Q200 qualified and lacks automotive-specific qualification testing. While its 150 °C Tj rating and robust guard ring support harsh environments, it is intended for industrial, consumer, and computing applications-not safety-critical automotive ECUs or ADAS subsystems.
How does the SOD323F package compare to SOD123F in thermal performance?
SOD323F has slightly higher Rth(j-a) (350 K/W vs. 330 K/W for SOD123F), but nearly identical Rth(j-sp) (55 K/W vs. 60 K/W). The smaller SOD323F achieves comparable solder-point thermal transfer due to optimized lead geometry - enabling efficient heat extraction through the cathode pad despite reduced footprint.
Can PMEG3005EJ/ZLX replace a standard silicon diode like 1N4148 in reverse polarity protection?
Yes - with key advantages: 380 mV VF vs. ~1 V for 1N4148 at 10 mA reduces voltage drop and power loss by >60%. However, its 30 V VR is lower than 1N4148's 100 V, so it must only be used where reverse voltage remains within 30 V. Also, IR is higher (~30 μA vs. <5 nA), which matters in ultra-low-leakage bias networks.
