Product details
Overview
PMEG3010CEH-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 packaged in SOD123F. It is AEC-Q101 qualified and designed for automotive-grade low-voltage rectification and reverse polarity protection.
For engineers reviewing the PMEG3010CEH-QX datasheet, PMEG3010CEH-QX pinout, PMEG3010CEH-QX application, or PMEG3010CEH-QX equivalent, key selection criteria include its ultra-low VF (≤520 mV), 9 A non-repetitive peak forward current, 100 pF diode capacitance at 1 V, thermal resistance of 150 K/W to solder point, and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under transient conditions. Its low VF stems from optimized metal-semiconductor junction design, enabling high efficiency in low-voltage DC/DC stages where conduction loss dominates.
The device operates with a maximum junction temperature of 150 °C and exhibits reverse leakage of only 10 µA at VR = 30 V and 25 °C. Thermal performance is characterized by Rth(j-sp) = 150 K/W when mounted on FR4 with a 1 cm² cathode pad - critical for sustained 1 A operation in thermally constrained automotive modules.
Key Specifications

| Forward Current (IF) | 1 A continuous - suitable for auxiliary power rails and sensor supply circuits |
| Forward Voltage (VF) | 450 mV typ. at 1 A - reduces conduction loss by >30% vs. standard silicon diodes |
| Reverse Leakage (IR) | 10 µA max. at 30 V - minimizes standby power loss in always-on modules |

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 NSR30100XV6T1G | Same 30 V/1 A rating but VF = 490 mV typ.; no AEC-Q101 qualification | Approved for industrial/commercial use only; not validated for automotive temperature cycling | Select when cost sensitivity outweighs automotive qualification requirement |
| Vishay SS13HE3/5AT | Higher VF = 550 mV typ.; larger SMC package (7.1 mm × 6.2 mm); IF = 3 A | Used where surge current > 9 A or thermal mass demands larger footprint | Choose when higher IFSM or board-level thermal inertia is prioritized over space-constrained layout |
Compared with NSR30100XV6T1G and SS13HE3/5AT, PMEG3010CEH-QX delivers the lowest VF in its class with automotive qualification and smallest footprint - making it optimal for space- and efficiency-critical automotive modules where qualification and thermal density are mandatory.

FAQ
Is PMEG3010CEH-QX pin-compatible with standard SOD123 diodes?
Yes - it uses the industry-standard SOD123F package with identical 2.6 mm × 1.6 mm outline and 1.1 mm height, matching IPC-7351B footprint recommendations. Pin 1 is cathode (marked), Pin 2 is anode, fully compatible with existing SOD123 land patterns.
What is the maximum allowable PCB copper area for thermal relief at 1 A continuous?
With a 1 cm² cathode pad on FR4 (single-sided, tin-plated), Rth(j-sp) is 150 K/W - sufficient to maintain Tj ≤ 125 °C at Tamb = 85 °C and 1 A. No additional heatsinking is required for this configuration per Nexperia's thermal characterization.
Does PMEG3010CEH-QX support reflow soldering per JEDEC J-STD-020?
Yes - it is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C), with solder land dimensions specified in Figure 6 of the datasheet. The SOD123F package withstands thermal shock without delamination or parametric shift.
How does the guard ring affect reliability in automotive environments?
The integrated guard ring mitigates electric field crowding at the die edge, improving resistance to humidity-induced leakage and ESD events per AEC-Q101 HBM (≥8 kV) and CDM (≥1 kV) tests - directly enhancing long-term stability in under-hood temperature/humidity cycling.
