Product details
Overview
PMEG1030EH,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 10 V reverse voltage and 3 A forward current, featuring ultra-low 390–530 mV forward voltage at 3 A. It serves as a low-loss freewheeling or reverse-polarity protection diode in space-constrained DC/DC converters and automotive power rails.
For engineers reviewing the PMEG1030EH,115 datasheet, PMEG1030EH,115 pinout, PMEG1030EH,115 application, or PMEG1030EH,115 equivalent, key selection criteria include its AEC-Q101 qualification, SOD123F package thermal resistance (Rth(j-sp) = 60 K/W), and low-VF performance at high ambient temperatures up to 150 °C.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under repetitive and non-repetitive peak currents (IFRM = 5.5 A, IFSM = 9 A). Its low junction-to-solder-point thermal resistance (60 K/W) enables reliable operation on FR4 PCBs with minimal copper area.
The device exhibits strong temperature stability: forward voltage increases only modestly with junction temperature, while reverse leakage remains below 3 mA at 10 V and 25 °C - critical for low-power standby circuits and battery-powered systems requiring minimal quiescent loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V - supports input rails up to 9 V nominal with margin for transients in automotive 12 V systems. |
| Forward Current (IF) | 3 A continuous - suitable for point-of-load converters delivering ≤3 A without forced cooling. |
| Forward Voltage (VF) | 390–530 mV @ 3 A - reduces conduction loss by >40% vs. standard silicon diodes, improving efficiency in 3.3 V/5 V buck outputs. |
| Reverse Leakage (IR) | 1–3 mA @ 10 V, 25 °C - low enough to avoid significant standby drain in always-on automotive modules. |
| Diode Capacitance (Cd) | 70–85 pF @ 1 V, 1 MHz - minimizes switching noise and EMI in high-frequency (>500 kHz) SMPS designs. |
| Junction Temp (Tj) | 150 °C max - enables operation in engine-bay-adjacent locations without derating below full current. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114. |
Pinout & Package
Encapsulated in a compact SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), the PMEG1030EH,115 features flat leads optimized for thermal transfer to PCB copper. The cathode is marked by a bar on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output rail or ground return path; marking bar identifies this terminal for correct PCB layout orientation. |
| 2 (A) | Anode | Connected to input or switching node; polarity-sensitive placement prevents reverse conduction failure in reverse polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 390 mV typ. @ 3 A enables ≥2% efficiency gain over comparable 10 V Schottkys in 5 V buck converters. |
| Integrated guard ring | Suppresses edge breakdown under voltage stress, increasing long-term reliability in noisy automotive environments. |
| SOD123F thermal design | 60 K/W junction-to-solder-point resistance allows 3 A operation on 1 cm² cathode pad without heatsink. |
| AEC-Q101 qualification | Validated for automotive use including 1000-cycle temperature cycling (-40 °C to +125 °C) and 1000 h HTRB. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |

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 NSS10300U1T1G | Same 10 V/3 A rating but higher VF (450–600 mV @ 3 A); SOD-123 package (slightly larger footprint). | Lacks AEC-Q101 qualification; not recommended for automotive production. | Select when cost sensitivity outweighs automotive compliance and lowest possible VF. |
| Vishay SS13HE3/5BT | 3 A/30 V rating; higher reverse voltage but 100 mV higher typical VF at 3 A (490 mV); same SOD123F footprint. | Better surge tolerance due to higher VR, but increased conduction loss reduces efficiency in 5 V systems. | Prefer where system-level transient protection exceeds 10 V, e.g., 24 V industrial inputs with local clamping. |
Compared with NSS10300U1T1G and SS13HE3/5BT, PMEG1030EH,115 delivers the lowest verified VF in its class and is the only AEC-Q101-qualified option with 60 K/W Rth(j-sp), making it optimal for thermally constrained automotive and portable applications demanding both efficiency and reliability.

FAQ
What is the maximum allowable PCB pad size for thermal performance?
The datasheet specifies two mounting conditions: standard footprint yields Rth(j-a) = 330 K/W, while a 1 cm² cathode pad achieves Rth(j-sp) = 60 K/W. For full 3 A operation without derating, use the 1 cm² pad per Figure 6 footprint - minimum dimensions 2.1 mm × 1.2 mm solder land with 1.1 mm paste deposit per lead.
Is PMEG1030EH,115 suitable for synchronous rectification replacement?
No - it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. However, its ultra-low VF makes it a preferred alternative to active solutions in low-cost, low-complexity 5–12 V DC/DC stages where gate drive overhead is undesirable and efficiency gains over standard diodes exceed 1.5%.
How does the guard ring affect layout requirements?
The integrated guard ring eliminates need for extra keep-out zones around the die edges. Layout follows standard SOD123F footprint (Figure 6); no additional spacing beyond the 0.55 mm minimum lead-to-lead clearance is required. Guard ring functionality is internal and does not impose external routing constraints.
Can PMEG1030EH,115 be used in parallel for higher current?
Not recommended - Schottky diodes exhibit negative temperature coefficient for VF, causing current hogging. Parallel operation requires matched VF bins and individual current-limiting resistors. For >3 A, select a single higher-rated device such as PMEG2020AEL (20 V/2 A) in parallel configuration or PMEG3010CEH (30 V/10 A) in SOD128.
