Product details
Overview
PMEG1020EA-QX from Nexperia is a 2 A, 10 V ultra-low forward voltage Schottky barrier rectifier in SOD323F (SC-76) package, featuring 280 mV typical VF at 1 A, AEC-Q101 qualification, and integrated guard ring for stress protection-used in automotive DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG1020EA-QX datasheet, PMEG1020EA-QX pinout, PMEG1020EA-QX application, or PMEG1020EA-QX equivalent, key selection criteria include ultra-low VF performance at low currents (100 mV @ 0.01 A), thermal resistance to solder point (90 K/W), AEC-Q101 qualification, and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This planar Schottky diode employs an integrated guard ring structure to enhance robustness against electrical overstress and thermal runaway-critical in automotive 12 V rail applications. Its low-junction-capacitance (37–45 pF @ 5 V) and fast switching enable efficient operation in high-frequency SMPS topologies up to several MHz.
The device operates across –65 °C to +150 °C ambient and junction temperatures, with defined thermal resistance paths: 450 K/W (junction-to-ambient, FR4 single-sided), 210 K/W (junction-to-solder-point, 10×10 mm copper), and 90 K/W (cathode tab to solder point)-enabling accurate thermal modeling in constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 280 mV typ @ 1 A, pulsed - enables >95% efficiency in 3.3 V/5 V buck converters at light-to-moderate loads |
| Reverse Voltage (VR) | 10 V max - suitable for 12 V automotive systems with transient suppression margin |
| Average Forward Current (IF) | 2 A @ Tsp ≤ 55 °C - defines continuous conduction capability under board-level thermal constraints |
| Reverse Current (IR) | 1.2–3 mA @ VR = 10 V, 25 °C - impacts standby power loss in reverse-polarity protection |
| Diode Capacitance (Cd) | 37–45 pF @ VR = 5 V, 1 MHz - limits high-frequency switching noise and EMI in MHz-range DC/DC stages |
| Junction-to-Solder-Point Rth | 90 K/W - enables direct thermal coupling to copper pour for localized heat extraction in compact modules |
Pinout & Package
Encapsulated in SOD323F (SC-76), a 1.7 mm × 1.25 mm × 0.95 mm surface-mount plastic package with 1.3 mm lead pitch and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Primary current exit path; connected to PCB copper pour for thermal management and reverse-polarity ground reference |
| 2 (A) | Anode | Input-side terminal; routed away from sensitive analog traces to minimize forward conduction noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments per stress test requirements (HTOL, TC, HAST, etc.) |
| Ultra-low VF at low IF | 100 mV typ @ 0.01 A - reduces dropout and improves regulation in always-on microcontroller power rails |
| Guard ring integration | Enhances ruggedness against ESD and voltage transients without external TVS components |
| SOD323F footprint | Enables <1.5 mm² board area usage - critical for space-constrained ADAS sensor modules and body control units |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |
|---|---|

FAQ
Is PMEG1020EA-QX suitable for synchronous rectification?
No-PMEG1020EA-QX is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET-based solution. It lacks gate drive interface or control logic. It functions as a freewheeling or OR-ing diode in non-synchronous topologies where its ultra-low VF provides efficiency gains without control complexity.
What is the maximum allowable soldering temperature profile for SOD323F?
The SOD323F package supports standard lead-free reflow per J-STD-020: peak temperature ≤ 260 °C, time above 217 °C ≤ 60 seconds, and ramp rate ≤ 3 °C/s. Figure 6 in the datasheet specifies the recommended reflow footprint with 0.5 mm × 0.6 mm solder lands and 1.5 mm transport direction alignment.
How does the guard ring affect layout requirements?
The integrated guard ring requires no special PCB layout but mandates adherence to the SOD323 outline (Figure 5) and minimum creepage/clearance distances per IEC 60664-1. No additional guard traces or slots are needed-the protection is monolithic and process-integrated within the die structure.
Can PMEG1020EA-QX replace PMEG2010AEA in the same footprint?
No-PMEG2010AEA uses SOD123 package (3.7 mm × 1.6 mm), while PMEG1020EA-QX uses SOD323F (1.7 mm × 1.25 mm). The footprints are incompatible: SOD323F has 1.3 mm lead pitch and smaller body dimensions, requiring dedicated land pattern per Figure 6.
