Product details
Overview
PMEG3020EH-QX from Nexperia is a 30 V, 2 A ultra-low forward voltage Schottky barrier rectifier in SOD123F package, featuring integrated guard ring for stress protection and AEC-Q101 qualification. It delivers 510–620 mV VF at 2 A (pulsed), 60–150 µA IR at 10 V, and 60–72 pF capacitance at 1 V - enabling high-efficiency low-voltage DC/DC conversion in automotive power rails.
For engineers reviewing the PMEG3020EH-QX datasheet, PMEG3020EH-QX pinout, PMEG3020EH-QX application, or PMEG3020EH-QX equivalent, key selection criteria include its ultra-low VF performance at high current, AEC-Q101 qualification for under-hood use, thermal resistance of 150 K/W (junction-to-solder point), and SOD123F footprint compatibility with space-constrained PCB layouts.
Technical Context
This planar Schottky diode uses an integrated guard ring to suppress edge breakdown under transient stress, improving reliability in automotive environments where load dump and reverse battery conditions occur. Its low VF minimizes conduction loss while maintaining low leakage (≤1000 µA at 30 V) and low junction capacitance (≤72 pF), supporting fast switching in synchronous rectification and reverse polarity protection circuits.
The device operates across –65 °C to +150 °C ambient and junction temperature ranges, with thermal resistance from junction to solder point rated at 150 K/W on standard FR4 PCB. Repetitive peak forward current reaches 4.5 A (tp ≤ 1 ms, δ ≤ 0.25), and non-repetitive surge withstand is 9 A (tp = 8 ms square wave), meeting stringent automotive transient requirements.
Key Specifications

|---|---|
|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller, CAN transceiver, and LED drivers. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between connector and main power distribution network. Use Value: 510 mV VF limits voltage drop to <0.5% at 2 A, preserving brown-out margin; AEC-Q101 rating ensures operation at 125 °C ambient. |
Use Scenario: Input-side reverse polarity and backfeed protection in 20 W USB-C PD adapter secondary side. IC Role / Device Role / Timing Role: Low-loss OR-ing diode preventing backfeed from output capacitor into failed primary controller. Use Value: 60 pF capacitance minimizes high-frequency ringing during 300 kHz–1 MHz switching; SOD123F footprint fits tight layout constraints near USB-C port. |
| Industrial IoT Sensor Node Power Path | Low-Power DC/DC Converter Output Rectification |
|
Use Scenario: Dual-input power selection (battery + energy harvester) with automatic switchover in wireless sensor node. IC Role / Device Role / Timing Role: Discrete Schottky diode in ideal diode configuration - no control IC required due to low VF threshold. Use Value: 125–160 mV VF at 1 mA enables reliable turn-on even with weak harvester sources (<100 mW); -65 °C to 150 °C rating covers outdoor deployment. |
Use Scenario: Synchronous rectification replacement in 3.3 V/2 A buck converter for FPGA I/O bank supply. IC Role / Device Role / Timing Role: Freewheeling diode conducting during high-side FET off-time - critical for light-load efficiency. Use Value: 255–290 mV VF at 100 mA reduces light-load conduction loss by 40% vs. standard Schottky; low Cd avoids gate drive coupling issues. |
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 NSS40201MR6T1G | Same 30 V VR, 2 A IF, but VF = 550–700 mV @ 2 A; SOD-123 package (not SOD123F); Rth(j-a) = 340 K/W | Lacks AEC-Q101 qualification; higher VF increases conduction loss by ~0.15 W at 2 A | Prefer for cost-sensitive industrial designs where automotive qualification is unnecessary |
| Vishay VS-2EY30HM3/H | Higher VR = 30 V, same IF = 2 A, but VF = 590–750 mV @ 2 A; SMA package (larger footprint); qualified to AEC-Q101 | SMA package requires 3.5× more board area; higher VF degrades light-load efficiency in DC/DC converters | Choose only when existing SMA footprint must be retained or higher surge rating (12 A IFSM) is required |
Compared with NSS40201MR6T1G and VS-2EY30HM3/H, PMEG3020EH-QX offers the lowest VF in its class with AEC-Q101 validation and smallest footprint - making it optimal for thermally constrained, high-efficiency automotive and portable power applications where board space and conduction loss are critical.

FAQ
What is the maximum continuous forward current rating for PMEG3020EH-QX?
The PMEG3020EH-QX is rated for 2 A continuous forward current at a solder point temperature (Tsp) ≤ 55 °C. This rating assumes mounting on FR4 PCB with single-sided copper and standard SOD123F footprint. Derating is required above 55 °C Tsp, with junction temperature limited to 150 °C.
Does PMEG3020EH-QX require a heatsink in typical 2 A applications?
No external heatsink is required. With Rth(j-sp) = 150 K/W and typical power dissipation of ~1.1 W at 2 A, junction-to-solder-point temperature rise is ~165 K - manageable within the 150 °C max Tj limit when ambient and board thermal design keep solder point ≤ 55 °C. Copper pour under the cathode pad further enhances thermal performance.
How does the integrated guard ring improve reliability?
The integrated guard ring mitigates electric field crowding at the silicon periphery, suppressing premature edge breakdown during voltage transients like load dump (ISO 7637-2 Pulse 5a). This extends operational lifetime in automotive environments where repetitive overvoltage stress would otherwise accelerate degradation of unguarded Schottky structures.
Can PMEG3020EH-QX replace standard PN-junction diodes in 12 V systems?
Yes - its 30 V VR and ultra-low VF provide superior efficiency versus 1N4007 or 1N5819 in 12 V rectification. At 2 A, VF is ~550 mV versus ~900 mV for 1N5819, reducing conduction loss by 0.7 W. However, its higher IR (up to 1000 µA at 30 V) requires verification in high-impedance bias networks where leakage could affect accuracy.
