Product details
Overview
PMEG1030EH-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 10 V reverse voltage and 3 A forward current, featuring ultra-low 390–530 mV forward voltage at 3 A, housed in an AEC-Q101-qualified SOD123F surface-mount package for automotive-grade low-voltage rectification and DC-DC conversion.
For engineers reviewing the PMEG1030EH-QX datasheet, PMEG1030EH-QX pinout, PMEG1030EH-QX application, or PMEG1030EH-QX equivalent, key selection criteria include its 390 mV typical VF at 3 A, 10 V VR rating, 70–85 pF junction capacitance, thermal resistance of 150 K/W (junction-to-solder point), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve robustness against transient overvoltage and ESD stress. Its ultra-low forward voltage stems from optimized metal-semiconductor interface design and low-resistance cathode metallization.
Thermal performance is defined by two critical paths: Rth(j-a) = 330 K/W (free air) and Rth(j-sp) = 150 K/W (to solder point on FR4 PCB), enabling reliable operation up to 150 °C junction temperature while supporting high pulse currents (IFSM = 9 A, 8 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V - Maximum continuous blocking voltage before breakdown; defines suitability for ≤12 V automotive rail protection. |
| Forward Current (IF) | 3 A - Continuous DC current rating at Tsp ≤ 55 °C; supports compact power stage designs without forced cooling. |
| Forward Voltage (VF) | 390–530 mV @ 3 A - Ultra-low conduction loss enables >95% efficiency in 3.3 V/5 V buck converter outputs. |
| Junction Capacitance (Cd) | 70–85 pF @ 1 V - Low capacitance minimizes switching losses and EMI in high-frequency (>1 MHz) DC-DC topologies. |
| Reverse Current (IR) | 1–3 mA @ 10 V - Low leakage preserves battery life in always-on automotive modules (e.g., CAN transceiver standby). |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Enables direct thermal coupling to PCB copper; allows 830 mW dissipation with 1 cm² cathode pad. |
Pinout & Package
Encapsulated in the SOD123F package (2.6 mm × 1.6 mm × 1.1 mm body), this 2-terminal device uses a flat-lead surface-mount outline with standardized footprint per Nexperia's reflow soldering guidelines (Fig. 6). The cathode is marked by a bar on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connected to load ground or return path; marking bar identifies this pin. |
| 2 | Anode (A) | Positive input terminal; connects to source rail or switch node; carries full forward current during conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge-related avalanche breakdown, improving surge immunity and long-term reliability in automotive transients. |
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS power supplies. |
| Ultra-low VF at high IF | 390 mV typical at 3 A enables minimal self-heating and eliminates need for heatsinking in space-constrained modules. |
| SOD123F package | Small footprint (2.6 × 1.6 mm) with flat leads ensures compatibility with automated pick-and-place and reflow processes. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection for 12 V supply rails feeding microcontrollers and LIN transceivers. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with input rail to prevent damage from battery misconnection. Use Value: 390 mV VF limits voltage drop to <0.4 V at 3 A, preserving headroom for 5 V LDOs and avoiding thermal derating. |
Use Scenario: Output OR-ing diode in dual-input USB-C PD power path (e.g., adapter + battery). IC Role / Device Role / Timing Role: Low-loss conduction path that blocks reverse current when one source is inactive. Use Value: 70–85 pF Cd and fast recovery minimize switching noise during source handover, reducing EMI filter burden. |
| Industrial 24 V DC-DC Converter | Low-Power IoT Sensor Node |
Use Scenario: Secondary-side synchronous rectification replacement in isolated flyback converters delivering 5 V/2 A. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time to complete inductor current path. Use Value: 3 A IF rating and 150 K/W Rth(j-sp) allow operation at 75 °C ambient without derating in sealed enclosures. |
Use Scenario: Battery backup diode isolating primary Li-ion cell from supercapacitor charging circuit. IC Role / Device Role / Timing Role: Leakage-suppressing isolation element preventing self-discharge during sleep mode. Use Value: 1–3 mA IR at 10 V ensures <1 µA drain from 3.6 V battery over 10-year shelf life in cold storage. |
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 SOD123F package; 10 V/3 A rating; VF = 420–550 mV @ 3 A; no AEC-Q101 qualification. | Approved for industrial/commercial use only; not validated for automotive temperature cycling or humidity testing. | Select when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs qualification requirements. |
| Vishay SS13HE3/5BT | SOD-123 package (not SOD123F); 30 V/3 A rating; VF = 450–600 mV @ 3 A; AEC-Q101 qualified. | Higher VR enables use in 24 V systems but increases parasitic capacitance (110 pF), raising EMI risk in high-frequency converters. | Select when higher reverse voltage margin is required and layout allows minor footprint adjustment (SOD-123 vs SOD123F). |
Compared with NSR1030HT1G, PMEG1030EH-QX provides guaranteed automotive qualification and lower typical VF; versus SS13HE3/5BT, it offers lower capacitance and tighter VF distribution at the expense of reduced VR margin-critical for 12 V rail integrity.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. For continuous 3 A operation, thermal design must ensure Tj remains ≤150 °C using the specified Rth(j-sp) = 150 K/W and appropriate PCB copper area (1 cm² cathode pad recommended). Derating begins above Tsp = 55 °C per datasheet limiting values.
Is PMEG1030EH-QX compatible with lead-free reflow profiles?
Yes-Nexperia specifies full compatibility with JEDEC J-STD-020D.2 lead-free reflow, with peak temperature up to 260 °C and time above liquidus (TAL) ≤60 seconds. The SOD123F package outline and solder land pattern in Figure 6 are optimized for this profile.
How does the guard ring affect surge withstand capability?
The integrated guard ring prevents premature edge breakdown during repetitive surge events (e.g., ISO 7637-2 Pulse 1/2a/5a), allowing the device to sustain IFSM = 9 A (8 ms square wave) without degradation. This extends lifetime in automotive load-dump scenarios compared to non-guarded Schottky diodes.
Can PMEG1030EH-QX replace standard PN-junction rectifiers in existing designs?
Yes-its 10 V VR and 3 A IF ratings match common 1N5819 equivalents, but with ~50% lower VF. Designers must verify layout clearance (SOD123F footprint differs slightly from DO-214AC) and confirm reverse leakage tolerance, as Schottky IR is higher than PN diodes at elevated temperatures.
