Product details
Overview
PMEG3010EB-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 610–680 mV forward voltage at 1 A, ultra-small SOD523 (SC-79) package, and AEC-Q101 qualification for automotive reverse polarity protection circuits.
For engineers reviewing the PMEG3010EB-QX datasheet, PMEG3010EB-QX pinout, PMEG3010EB-QX application, or PMEG3010EB-QX equivalent, key selection criteria include low VF performance at 1 A, thermal resistance to solder point (75 K/W), junction temperature limit of 150 °C, and automotive-grade reliability in space-constrained DC/DC converters.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under repetitive and non-repetitive peak currents up to 3 A and 5 A respectively. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency at low voltages.
Thermal behavior is defined by two critical paths: junction-to-ambient (400 K/W in free air) and junction-to-solder-point (75 K/W), where cathode tab soldering dominates heat extraction. Reverse leakage remains ≤500 µA at 30 V and 25 °C, supporting stable operation in low-power bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability without avalanche or degradation; suitable for 24 V automotive rail clamping. |
| Forward Current (IF) | 1 A continuous - Sustained conduction at ambient ≤55 °C on FR4 PCB; supports compact power path designs. |
| Forward Voltage (VF) | 610–680 mV at 1 A - Enables <1.2% conduction loss in 12 V systems; reduces heat generation vs. standard PN diodes. |
| Reverse Leakage (IR) | ≤500 µA at 30 V - Limits standby power loss in battery-backed circuits and low-quiescent DC/DC controllers. |
| Diode Capacitance (Cd) | 24–30 pF at 1 V - Minimizes switching node ringing in high-frequency (>1 MHz) buck converters. |
| Junction Temperature (Tj) | 150 °C max - Allows operation in under-hood automotive environments with localized heating. |
| Thermal Resistance (Rth(j-sp)) | 75 K/W - Confirms effective heat transfer via cathode pad; enables thermal design using standard SOD523 footprint. |
Pinout & Package
Encapsulated in SOD523 (SC-79) ultra-small surface-mount plastic package: 1.2 mm × 0.8 mm × 0.6 mm body, flat lead profile, single-sided copper FR4 mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked bar side) | Cathode (K) | Negative output terminal; marking bar identifies polarity for automated optical inspection and placement. |
| 2 | Anode (A) | Positive input terminal; connects to source-side of reverse polarity protection or switch-node in synchronous rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge electric field concentration, improving VR consistency and surge survivability per AEC-Q101 transients. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing-no derating required for passenger vehicle ECUs. |
| Ultra-low VF at 1 A | 610–680 mV enables >95% efficiency in 5–12 V buck converter outputs with minimal heatsinking. |
| SOD523 footprint | 1.2 mm × 0.8 mm area allows placement in tight spaces such as USB-C PD adapters and ADAS camera modules. |
| Low capacitance (24–30 pF) | Reduces switching losses and EMI in MHz-range DC/DC topologies without requiring snubber networks. |
Applications
| Automotive Reverse Polarity Protection | USB-C Power Delivery Input Stage |
|---|---|

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 NSR1030HT1G | Same SOD523 package; VF = 620–700 mV at 1 A; IR = 100–600 µA at 30 V; no AEC-Q101 certification. | Qualified for industrial but not automotive use; requires external transient protection in vehicle harness interfaces. | Select when AEC-Q101 is not mandated and cost sensitivity outweighs qualification overhead. |
| Vishay VSKY1102-G3-08 | SOD523 package; VF = 590–660 mV at 1 A; VR = 20 V; IR = 50–250 µA at 20 V; AEC-Q101 qualified. | Limited to 20 V systems; unsuitable for 24 V battery monitoring or CAN FD transceiver supplies. | Prefer for 12 V-only subsystems where lower VF justifies reduced voltage margin. |
Compared with NSR1030HT1G and VSKY1102-G3-08, PMEG3010EB-QX uniquely delivers 30 V rating with AEC-Q101 compliance and sub-680 mV VF in SOD523-enabling single-source qualification across 12 V and 24 V automotive domains without footprint change.

FAQ
Is PMEG3010EB-QX compatible with lead-free reflow soldering processes?
Yes. The device is qualified for JEDEC J-STD-020D-compliant lead-free reflow profiles, with peak temperatures up to 260 °C. The SOD523 package outline and recommended solder land pattern (Figure 6) ensure reliable wetting and void-free joints on standard FR4 PCBs.
What is the maximum allowable PCB copper area for thermal relief when mounting PMEG3010EB-QX?
No minimum copper area is specified, but thermal resistance data assumes a single-sided FR4 board with tin-plated copper and standard SOD523 footprint. Adding 2×2 mm² copper pour connected to the cathode pad reduces Rth(j-a) by ~30%, verified in Nexperia's thermal simulation reports.
Does the guard ring affect the device's reverse recovery time?
No-Schottky diodes like PMEG3010EB-QX have no minority-carrier storage, so reverse recovery time is effectively zero. The guard ring solely improves voltage standoff uniformity and transient robustness without introducing recovery delay or tail current.
Can PMEG3010EB-QX be used in parallel for higher current handling?
Not recommended. Forward voltage mismatch between units causes current imbalance; even 20 mV VF variation leads to >60% current sharing deviation at 1 A total. For >1 A, select a single higher-rated device such as PMEG3020EB-QX (2 A).
