Product details
Overview
PMEG3010CEJ-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 450 mV at 1 A and housed in an SOD323F (SC-90) surface-mount package. It is AEC-Q101 qualified and designed for low-voltage rectification and reverse polarity protection in automotive power rails.
For engineers reviewing the PMEG3010CEJ-QX datasheet, PMEG3010CEJ-QX pinout, PMEG3010CEJ-QX application, or PMEG3010CEJ-QX equivalent, key selection criteria include its ultra-low VF performance, thermal resistance to solder point (150 K/W), 10 A non-repetitive peak forward current capability, and automotive-grade reliability under transient stress conditions.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to suppress edge breakdown and improve robustness against voltage transients and ESD stress. Its low forward voltage stems from optimized metal-semiconductor interface engineering, enabling high conduction efficiency at low load currents.
The device operates within a junction temperature range of −65 °C to 150 °C and exhibits a diode capacitance of 90–100 pF at 1 V reverse bias and 1 MHz, supporting fast switching in DC-DC converters up to several hundred kHz without significant capacitive loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking voltage before breakdown; defines safe operating margin in 24 V automotive systems. |
| Forward Current (IF) | 1 A continuous - Rated for sustained conduction at ambient ≤55 °C on standard FR4 PCB; supports compact power rail designs. |
| Forward Voltage (VF) | 450 mV typ. at 1 A - Enables <150 mW conduction loss at full load, critical for thermally constrained modules. |
| Reverse Current (IR) | 10–50 µA at VR = 30 V - Low leakage preserves battery standby life in always-on automotive subsystems. |
| Diode Capacitance (Cd) | 90–100 pF at VR = 1 V, f = 1 MHz - Limits high-frequency switching losses and EMI generation in buck converter output stages. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Junction-to-solder-point value enables accurate thermal modeling when cathode pad is thermally enhanced. |
| Non-repetitive Peak IF (IFSM) | 10 A at tp = 8 ms - Supports surge immunity during load dump or hot-plug events in vehicle electronics. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat lead profile optimized for space-constrained automotive PCBs. Cathode identified by marking bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connects to system ground or lower-potential node; marked with bar on top surface. |

| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTGB, HTRB, and ESD-HBM ≥2 kV. |
| Ultra-low VF at 1 A | 450 mV typical enables >95% efficiency in 3.3 V/5 V synchronous rectifier replacement applications. |
| SOD323F footprint | Standardized 0.5 mm pitch, 1.35 mm pad length - compatible with automated reflow and AOI inspection in high-volume SMT lines. |
Applications

|---|---|
Use Scenario: Reverse polarity protection on 12 V supply input to microcontroller-based lighting control unit. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during battery misconnection. Use Value: 450 mV VF minimizes voltage drop across protection path, preserving headroom for LDO regulation downstream. |
Use Scenario: Input-side OR-ing diode in dual-source USB-C PD adapter with legacy barrel jack fallback. IC Role / Device Role / Timing Role: Low-loss conduction path selecting highest available source while blocking reverse current. Use Value: 100 pF capacitance avoids high-frequency ringing during source switchover, reducing EMI in noise-sensitive audio subsystems. |

Use Scenario: Supply isolation between Li-ion battery and BLE SoC during charging and sleep modes. IC Role / Device Role / Timing Role: Leakage-suppressing barrier maintaining <1 µA quiescent current in deep sleep state. Use Value: 10 µA max IR at 30 V ensures multi-year battery life without measurable self-discharge penalty. |
Use Scenario: Secondary-side rectifier in 3.3 V, 500 mA buck converter powering FPGA configuration memory. IC Role / Device Role / Timing Role: High-efficiency conduction element replacing synchronous MOSFET where gate drive complexity is prohibitive. Use Value: 150 mW conduction loss at full load reduces thermal load on 4-layer PCB, eliminating need for thermal vias. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS1C200LT1G | Higher VF (550 mV typ. at 1 A); same 30 V VR; SOD-323 package; no AEC-Q101 qualification. | Acceptable for industrial consumer power supplies but not certified for automotive underhood environments. | Select when cost sensitivity outweighs automotive qualification requirement and thermal margin permits +100 mV VF penalty. |
| Vishay SS12 | Higher IF rating (2 A), larger SMA package (4.5 mm × 2.7 mm); VF = 500 mV typ. at 1 A; AEC-Q101 qualified. | Requires 3× PCB area; suitable where surge current >10 A or board-level thermal mass supports higher dissipation. | Prefer when design requires >1 A continuous current headroom or existing layout accommodates SMA footprint. |
Compared with NSS1C200LT1G and SS12, PMEG3010CEJ-QX delivers the lowest VF in a qualified AEC-Q101 SOD323F package-enabling minimal voltage drop and smallest PCB footprint in space- and efficiency-critical automotive modules.

FAQ
Is PMEG3010CEJ-QX suitable for hot-swap applications?
Yes. With a non-repetitive peak forward current rating of 10 A for 8 ms and AEC-Q101 qualification for surge robustness, it withstands inrush currents during live insertion in automotive submodules. Its 150 °C max junction temperature supports operation near heat sources like motor drivers.
What is the thermal performance difference between standard and enhanced PCB mounting?
On standard FR4 with tin-plated single-sided copper, Rth(j-a) is 350 K/W. With a 1 cm² cathode pad, Rth(j-sp) drops to 150 K/W-enabling 2.3× higher power dissipation before reaching 150 °C junction limit. This allows 1 A continuous operation in tighter thermal envelopes.
Does the marking "EN" correspond to the full part number?
Yes. Per Nexperia's marking code table, "EN" is the unique top-side laser marking for PMEG3010CEJ-QX. It appears adjacent to the cathode bar on the SOD323F package and is verified in production traceability records.
Can PMEG3010CEJ-QX replace a standard silicon diode in an existing 24 V power supply?
Yes, provided VR ≥ 30 V and IF ≤ 1 A. Its 450 mV VF cuts conduction loss by ~65% versus a 1N4007 (VF ≈ 1.1 V), reducing thermal stress and improving efficiency-but verify reverse recovery behavior is not required, as Schottky diodes lack minority-carrier storage.
