Product details
Overview
PMEG1020EJ-QX from Nexperia is a 10 V, 2 A ultra-low forward voltage Schottky barrier rectifier in SOD323F (SC-90) package, designed for low-voltage DC-to-DC conversion and inverse polarity protection in automotive-grade power rails. It delivers VF = 350–460 mV at 2 A, IR ≤ 3 mA at 10 V, and is qualified to AEC-Q101.
For engineers reviewing the PMEG1020EJ-QX datasheet, PMEG1020EJ-QX pinout, PMEG1020EJ-QX application, or PMEG1020EJ-QX equivalent, key selection criteria include ultra-low VF at high current, thermal resistance Rth(j-sp) = 55 K/W, AEC-Q101 qualification, and SOD323F footprint compatibility with space-constrained automotive modules.
Technical Context
This planar Schottky diode integrates a guard ring for mechanical and electrical stress protection, enabling reliable operation under transient load conditions in automotive subsystems. Its low junction-to-solder-point thermal resistance (55 K/W) supports stable performance on FR4 PCBs with minimal copper area.
The device operates with reverse voltage up to 10 V and continuous forward current up to 2 A at Tsp ≤ 55 °C. Reverse leakage remains ≤ 2.5 mA at 8 V and 25 °C, while capacitance is 40–50 pF at 5 V and 1 MHz - critical for high-frequency switching node integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 2 A | 350–460 mV - enables ≥95% efficiency in 3.3 V/5 V buck converters at full load |
| VR | 10 V - suitable for 12 V automotive supply rail clamping and reverse polarity protection |
| IF (cont) | 2 A at Tsp ≤ 55 °C - defines maximum steady-state current with standard PCB mounting |
| IR @ 10 V | 1.2–3 mA - low leakage preserves battery life in always-on vehicle modules |
| Cd @ 5 V | 40–50 pF - minimizes switching losses and EMI in >1 MHz DC-DC topologies |
| Rth(j-sp) | 55 K/W - enables direct thermal coupling to cathode pad for improved power cycling reliability |
Pinout & Package
Encapsulated in SOD323F (SC-90), a 1.7 mm × 1.25 mm × 0.7 mm surface-mount plastic package with flat leads and optimized thermal pad layout for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary heat path; connects to large copper pour for thermal management and reverse voltage reference |
| 2 | Anode (A) | Input terminal for forward conduction; routed with low-inductance trace in high-dI/dt paths |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 350 mV typ. at 2 A - reduces conduction loss by >40% vs. standard Schottkys in 5 V rails |
| AEC-Q101 qualified | Stress-tested per automotive discrete semiconductor standard - supports PPAP and long-term field reliability |
| Integrated guard ring | Enhances ruggedness against ESD and voltage transients - eliminates need for external TVS in many 12 V input stages |
| SOD323F footprint | 1.7 mm × 1.25 mm body - fits dense layouts in ADAS camera modules and body control units |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection on 12 V input rail of door module MCU power supply. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection. Use Value: 350 mV VF limits voltage drop to <0.4 V at 2 A, preserving brown-out margin for 5 V LDO input. |
Use Scenario: Input clamp in USB-C PD sink circuit protecting 5–20 V input stage from backfeed. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) Schottky clamp limiting reverse conduction during hot-plug events. Use Value: 40–50 pF capacitance avoids signal integrity degradation on CC and VCONN lines. |
| Low-Power IoT Sensor Node | Industrial 24 V DC-DC Pre-Regulator |
Use Scenario: OR-ing diode in dual-supply (battery + USB) sensor hub with µA-level sleep current. IC Role / Device Role / Timing Role: Low-leakage (≤2 mA @ 10 V) isolation element minimizing quiescent drain. Use Value: IR ≤ 2 mA at 10 V ensures <20 µW standby dissipation - extends coin-cell life by >12 months. |
Use Scenario: Input rectifier in isolated flyback pre-regulator converting 24 V industrial bus to 12 V intermediate rail. IC Role / Device Role / Timing Role: High-current (2 A cont.) Schottky handling peak loads without thermal derating. Use Value: Rth(j-sp) = 55 K/W allows operation at 85 °C ambient with no heatsink on standard FR4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TR | Higher VF (450–550 mV @ 2 A); same 10 V VR; TO-220FP package | Requires heatsink above 1 A; unsuitable for space-constrained automotive PCBs | Prefer when higher surge current (IFSM = 100 A) is needed over VF optimization |
| SS210H | Lower IF rating (1 A cont.); VF = 500 mV @ 1 A; SMA package | Larger footprint (4.5 mm × 2.7 mm); not AEC-Q101 qualified | Select only for non-automotive consumer designs where cost outweighs thermal and qualification requirements |
Compared with RB050M-40TR and SS210H, PMEG1020EJ-QX uniquely combines AEC-Q101 qualification, ultra-low VF at full 2 A load, and SOD323F miniaturization - making it the only option meeting all three requirements for next-gen automotive power nodes.

FAQ
What is the maximum continuous forward current for PMEG1020EJ-QX at 85 °C ambient?
The datasheet specifies IF = 2 A maximum at Tsp ≤ 55 °C. At Tamb = 85 °C, derating applies: based on Rth(j-a) = 350 K/W and Tj(max) = 150 °C, usable IF drops to approximately 1.1 A with standard FR4 mounting. Thermal design must verify junction temperature using actual board layout.
Is PMEG1020EJ-QX suitable for reverse battery protection in 12 V systems?
Yes - its 10 V VR rating provides sufficient margin for 12 V nominal systems with typical transients (e.g., load dump up to 14 V). The integrated guard ring enhances robustness against repetitive 12 V reverse connection events, and VF < 460 mV ensures minimal voltage drop during normal operation.
How does the SOD323F package affect thermal performance compared to SOD123?
SOD323F offers lower Rth(j-sp) = 55 K/W versus ~100 K/W for standard SOD123 due to its exposed cathode pad and optimized solder land geometry. This enables 30–40% higher power handling on identical PCB area, critical for automotive modules where thermal headroom is constrained.
Does PMEG1020EJ-QX require a minimum cathode copper area for rated current?
Yes - the 2 A rating assumes a 1 cm² cathode pad on single-sided FR4 (tin-plated). Reducing pad area increases Rth(j-sp) and requires current derating; for example, halving pad area raises thermal resistance by ~25%, limiting safe IF to ~1.6 A at Tsp ≤ 55 °C.
