Product details
Overview
PMEG4002EJ from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 200 mA average forward current at ≤40 V reverse voltage, with typ. 520 mV forward voltage at 200 mA and <10 µA reverse leakage at 40 V, in a compact SOD323F (SC-90) surface-mount package.
For engineers reviewing the PMEG4002EJ datasheet, PMEG4002EJ pinout, PMEG4002EJ application, or PMEG4002EJ equivalent, key selection criteria include ultra-low VF for minimal conduction loss, 5 ns reverse recovery time for high-frequency switching, thermal performance on FR4 vs. ceramic PCBs, and SOD323F footprint compatibility in space-constrained power rails.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against voltage transients and electrostatic stress-critical for input-stage protection in portable and battery-powered systems. Its low junction capacitance (6 pF at 10 V) and fast trr (5 ns) support operation in MHz-range switching converters.
The device is rated for 150 °C maximum junction temperature and exhibits thermally dependent forward voltage drop (e.g., 440–500 mV at 100 mA, 25 °C), with derated IF(AV) up to 0.2 A depending on PCB thermal construction (FR4 standard footprint, FR4 with 1 cm² cathode pad, or Al₂O₃ ceramic).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 0.2 A - Maximum continuous forward current under defined thermal conditions (e.g., δ = 0.5, 20 kHz square wave, Tsp ≤ 145 °C) |
| VR | 40 V - Maximum repetitive reverse voltage before breakdown; sets usable input range in 24 V or 36 V systems |
| VF @ 200 mA | 520–600 mV - Low conduction loss enabling >90% efficiency in low-VOUT buck converters |
| IR @ 40 V | 0.7–10 µA - Minimal reverse leakage preserves battery life in always-on circuits |
| trr | 5 ns - Enables clean switching in >1 MHz SMPS without tail current losses |
| Cd @ 10 V | 6 pF - Low junction capacitance minimizes switching node ringing and EMI |
| Rth(j-a) | 325 K/W (FR4, std.) - Thermal resistance dictates max ambient temperature for full 0.2 A load |
Pinout & Package
Encapsulated in the SOD323F (SC-90) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat leads, optimized for reflow soldering only. Dimensions comply with JEDEC MO-203AA.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output/positive rail in reverse polarity protection; carries full forward current and anchors thermal path to PCB copper |
| 2 (A) | Anode | Connected to input/negative rail; forms low-VF conduction path when forward-biased; electrically isolated from cathode tab |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness and ESD tolerance (IEC 61000-4-2 Level 3) without external components |
| Low VF at 200 mA | 520 mV typical enables ≥30 mW lower power dissipation vs. comparable 0.2 A Schottkys in 3.3 V/5 V rails |
| Ultra-fast trr | 5 ns allows use in synchronous rectifier topologies up to 2 MHz without cross-conduction risk |
| SOD323F footprint | Standardized 0.5 mm pitch, 0.3 mm lead width supports automated placement and IPC Class 3 assembly |
| Reflow-only soldering | Guarantees mechanical integrity and thermal reliability-wave soldering voids warranty and risks delamination |
Applications
| USB Power Input Protection | DC-DC Converter Output Rectification |
|---|---|
|
Use Scenario: Protecting microcontroller-based peripherals from reversed USB cable insertion. IC Role / Device Role / Timing Role: Unidirectional current gate placed between VBUS and system input, conducting only when polarity is correct. Use Value: 0.52 V forward drop limits voltage loss to <2% at 200 mA, preserving 4.8 V minimum for 5 V logic; guard ring withstands ±8 kV contact ESD per IEC 61000-4-2. |
Use Scenario: Secondary-side rectification in 1 MHz, 3.3 V/1 A buck converter for FPGA I/O banks. IC Role / Device Role / Timing Role: High-frequency freewheeling diode replacing synchronous MOSFET where gate drive complexity is prohibitive. Use Value: 5 ns trr eliminates reverse recovery spikes that would otherwise degrade efficiency by >1.5% and increase EMI filter size by 30%. |
| Battery Backup Diode | Low-Power Sensor Node Rail OR-ing |
|
Use Scenario: Preventing primary battery discharge into backup coin cell during main power failure in IoT edge nodes. IC Role / Device Role / Timing Role: Isolation diode in series with backup supply path; blocks reverse current while minimizing standby loss. Use Value: 0.7 µA max IR at 3 V ensures <2.1 nA leakage-induced capacity loss per hour-extending CR2032 life by >18 months in sleep mode. |
Use Scenario: OR-ing two independent 3.3 V LDO outputs (e.g., main + backup regulator) to feed a wireless MCU. IC Role / Device Role / Timing Role: Passive rail selector ensuring seamless switchover without control logic or timing delays. Use Value: 0.2 A rating supports peak 150 mA transmit bursts; 6 pF capacitance avoids signal integrity degradation on 10 Mbps UART lines sharing same PCB net. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-40T1G | Higher VF (600 mV typ. @ 200 mA); same 40 V VR; SOD-523 package (smaller, 1.2 × 0.8 mm) | Less thermal margin on FR4 due to smaller pad area; suitable only for <150 mA continuous loads in same layout | Select when board space is constrained below 1.3 mm² and 80 mV higher conduction loss is acceptable |
| NSR0240HT1G | Lower VR (40 V same), but higher IR (50 µA @ 40 V); VF = 550 mV typ.; SOD-123FL package (larger, 2.9 × 1.5 mm) | Higher leakage reduces battery hold-up time in always-on sensors; better thermal dissipation for >0.25 A pulsed loads | Select when thermal design prioritizes long-term reliability over ultra-low standby current |
Compared with RB521S-40T1G and NSR0240HT1G, PMEG4002EJ offers the optimal balance of ultra-low VF, sub-1 µA leakage, and SOD323F manufacturability-making it preferred for high-efficiency, space-limited, battery-sensitive applications where both conduction loss and standby drain must be minimized simultaneously.

FAQ
Is PMEG4002EJ qualified for automotive applications?
No. Per Nexperia's revision history (v.3, October 2025), PMEG4002EJ is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-specific process controls. For automotive use, Nexperia recommends the -Q qualified variant PMEG4002EJ-Q, which undergoes extended temperature cycling, HTOL, and ESD validation per AEC standards.
What is the maximum allowable soldering temperature profile for PMEG4002EJ?
PMEG4002EJ is qualified for reflow soldering only, with peak temperature not exceeding 260 °C for ≤30 seconds (per JEDEC J-STD-020). The recommended profile follows IPC-7095B for small-outline diodes: preheat (125–150 °C), soak (150–200 °C for 60–120 s), ramp-up (<3 °C/s), reflow (peak 245–260 °C), and cooling. Wave soldering is prohibited and voids warranty.
How does thermal performance differ between FR4 and ceramic PCB mounting?
On standard FR4 (single-sided copper), Rth(j-a) is 325 K/W; with a 1 cm² cathode pad, it improves to 180 K/W. On Al₂O₃ ceramic, Rth(j-a) drops to 120 K/W. This means at 0.2 A and 25 °C ambient, junction temperature rises by ~65 °C on FR4 vs. ~24 °C on ceramic-directly impacting long-term reliability and derating margins in sealed enclosures.
Can PMEG4002EJ replace a standard PN-junction diode like 1N4148 in high-speed switching?
Yes, but only where low forward voltage and fast recovery are required-and reverse voltage stays ≤40 V. Unlike 1N4148 (100 V VR, 4 ns trr but 1.25 V VF), PMEG4002EJ cuts conduction loss by >50% at 200 mA, yet its 5 ns trr is comparable. However, its higher IR (µA vs. nA) makes it unsuitable for precision analog signal clamping or high-impedance bias networks.
