Product details
Overview
PMEG3010EJ-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 1 A forward current and 30 V reverse voltage, featuring a typical forward voltage of 450 mV at 1 A and qualified to AEC-Q101 for automotive use in low-voltage DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3010EJ-QX datasheet, PMEG3010EJ-QX pinout, PMEG3010EJ-QX application, or PMEG3010EJ-QX equivalent, key selection criteria include ultra-low VF performance at low currents (150 mV at 1 mA), thermal resistance to solder point (150 K/W), junction temperature limit (150 °C), and SOD323F package compatibility with high-density automotive PCB layouts.
Technical Context
This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low barrier height enables sub-500 mV forward voltage at rated current while maintaining 30 V blocking capability.
The device operates within −65 °C to 150 °C ambient and junction temperature ranges, with thermal performance defined for two PCB mounting conditions: standard footprint (Rth(j-a) = 350 K/W) and enhanced cathode pad (Rth(j-sp) = 150 K/W), enabling precise thermal design in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 1 A continuous - supports compact 12 V/5 V DC/DC output stages without forced cooling |
| Reverse Voltage (VR) | 30 V - suitable for 24 V automotive systems with margin against load dump transients |
| Forward Voltage (VF) | 450 mV typ. @ 1 A - reduces conduction loss by >30% vs. standard Schottkys in low-power buck regulators |
| Reverse Current (IR) | 40 µA max. @ 30 V - ensures minimal leakage in battery-backed keep-alive circuits |
| Diode Capacitance (Cd) | 55–70 pF @ 1 V - enables clean switching in >1 MHz SMPS designs with low EMI generation |
| Junction Temperature (Tj) | 150 °C max - allows operation in engine bay environments without derating below full current |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
Encapsulated in SC-90 (SOD323F) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.7 mm body, 2-lead configuration with gull-wing terminations optimized for reflow soldering on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current exit path; connects to ground or low-side return; thermal pad location for heat transfer |
| 2 | Anode (A) | Current entry point; ties to input rail or switch node; electrically isolated from cathode tab |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under high dv/dt, improving surge robustness in automotive transients |

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 | 30 V VR, 1 A IF, 550 mV VF @ 1 A, SOD-123 package (larger footprint) | Higher thermal resistance (400 K/W j-a); less suited for ultra-dense layouts | Select when board space permits larger package and higher VF is acceptable for cost-sensitive non-automotive designs |
| Vishay VS-1EQH03-M3/84A | 30 V VR, 1 A IF, 490 mV VF @ 1 A, SOD-123FL package, AEC-Q101 qualified | Higher leakage (100 µA @ 30 V); lower surge rating (IFSM = 6.5 A) | Prefer where tighter VF tolerance is needed but lower surge immunity is acceptable in cabin electronics |
Compared with NSS1C200LT1G and VS-1EQH03-M3/84A, PMEG3010EJ-QX delivers the lowest forward voltage (450 mV typ.) in the smallest AEC-Q101-qualified SOD323F package, making it optimal for thermally constrained automotive power rails requiring minimal conduction loss and maximum layout density.

FAQ
What is the maximum allowable soldering temperature profile for PMEG3010EJ-QX?
The device complies with JEDEC J-STD-020D for reflow soldering: peak temperature ≤ 260 °C for ≤ 30 seconds, with ramp-up rate ≤ 3 °C/s and ramp-down rate ≤ 6 °C/s. The recommended footprint matches Figure 6 in the datasheet, using 0.5 mm wide solder lands with 0.6 mm spacing.
Does PMEG3010EJ-QX support bidirectional current flow?
No - PMEG3010EJ-QX is a unidirectional Schottky rectifier. It conducts current only from anode to cathode and blocks reverse current up to 30 V. Bidirectional operation would require external circuitry such as back-to-back configurations or dedicated bidirectional switches.
How does the guard ring affect electrical performance under transient conditions?
The integrated guard ring prevents premature edge breakdown during fast voltage transients (e.g., ISO 7637-2 pulse 5a), maintaining stable 30 V blocking capability and reducing failure risk in automotive load-dump scenarios without increasing forward voltage or capacitance.
Can PMEG3010EJ-QX replace a standard PN-junction diode in existing designs?
Yes - it can directly replace PN diodes like 1N4148 or BAS16 in low-voltage, low-current applications, delivering lower forward voltage (450 mV vs. ~700–900 mV), faster switching, and zero minority-carrier recovery. Verify layout clearance and thermal pad design due to its SOD323F footprint.
