Product details
Overview
PMEG3005EJ-QX from Nexperia is a 30 V, 0.5 A planar Schottky barrier rectifier in SOD323F (SC-90) package, featuring 380–430 mV forward voltage at 500 mA, AEC-Q101 qualification, and integrated guard ring for stress protection-used in automotive reverse polarity protection and low-voltage DC/DC converters.
For engineers reviewing the PMEG3005EJ-QX datasheet, PMEG3005EJ-QX pinout, PMEG3005EJ-QX application, or PMEG3005EJ-QX equivalent, key selection criteria include ultra-low VF, thermal resistance (Rth(j-sp) = 55 K/W), AEC-Q101 compliance, and SOD323F footprint compatibility with space-constrained automotive power rails.
Technical Context
This MEGA Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown under high dv/dt or surge stress-critical for automotive load-dump immunity. Its low junction-to-solder-point thermal resistance (55 K/W) enables reliable operation up to 150 °C junction temperature on standard FR4 PCBs.
The device delivers 380–430 mV VF at 500 mA with <150 µA IR at 30 V reverse bias, and exhibits 55–70 pF capacitance at 1 V, supporting high-frequency switching in compact buck converters and USB power delivery paths where conduction loss and reverse recovery are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 500 mA | 380–430 mV - Enables >92% efficiency in 3.3 V/5 V synchronous buck stages by minimizing conduction loss. |
| VR | 30 V - Supports 24 V automotive systems with margin for ISO 7637-2 pulse 5a (load dump up to 35 V). |
| IF(AV) | 0.5 A - Rated for continuous operation at ambient ≤55 °C on standard FR4, suitable for auxiliary rail rectification. |
| IR @ 30 V | 40–150 µA - Low leakage preserves battery life in always-on automotive modules (e.g., CAN transceiver standby). |
| Cd @ 1 V | 55–70 pF - Minimizes switching node ringing and EMI in high-frequency (>1 MHz) DC/DC designs. |
| Rth(j-sp) | 55 K/W - Enables direct thermal coupling to copper pour, reducing thermal derating in dense layouts. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors (HTGB, HTRB, TST, etc.). |
Pinout & Package
Encapsulated in SOD323F (SC-90): 1.7 mm × 1.25 mm × 0.7 mm body, flat leads, cathode marked by bar.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marking bar identifies this pin-must connect to lower-potential node (e.g., ground or output rail). |
| 2 | Anode (A) | Input terminal for forward conduction; connects to higher-potential source (e.g., input rail or switch node). |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 380–430 mV at 500 mA reduces I²R loss by >40% vs. standard Schottkys, extending battery runtime in portable automotive sensors. |
| Integrated guard ring | Suppresses edge avalanche during transient overvoltage, eliminating need for external TVS in cost-sensitive reverse polarity circuits. |
| SOD323F package | 0.7 mm height and 1.25 mm width enable placement beneath connectors or near ICs in space-limited ADAS camera modules. |
| AEC-Q101 qualification | Validated for automotive underhood environments (−40 °C to +150 °C), enabling drop-in use without requalification in Tier-1 BOMs. |
Applications
| Automotive Reverse Polarity Protection | Low-Voltage DC/DC Converter Output Rectification |
|---|---|
Use Scenario: Protecting 12 V/24 V infotainment head units from battery misconnection during service. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between battery input and system LDO/regulator input. Use Value: 380 mV VF limits voltage drop to <0.4 V at 0.5 A, preserving >96% of input voltage for downstream regulators. |
Use Scenario: Output rectification in 5 V → 3.3 V buck converter for automotive body control modules. IC Role / Device Role / Timing Role: Freewheeling path during low-side switch off-time in asynchronous buck topology. Use Value: 55 pF capacitance minimizes switching node oscillation, reducing conducted EMI without snubber components. |
| USB-C Power Delivery Input Protection | Always-On Automotive Sensor Rail Clamping |
Use Scenario: Input-side polarity protection for USB-C PD sink controllers in telematics gateways. IC Role / Device Role / Timing Role: Series-blocking diode before PD controller's VBUS input to prevent damage from reversed cables. Use Value: 150 µA max IR at 30 V ensures <4.5 µW standby loss-critical for meeting UCISS sleep current budgets. |
Use Scenario: Clamp diode on 5 V sensor supply rail (e.g., radar MMIC bias) in parking assist ECUs. IC Role / Device Role / Timing Role: Reverse-biased protection element shunting transient spikes from nearby solenoid drivers. Use Value: Guard ring structure withstands 10 A non-repetitive surge (8 ms), eliminating need for parallel TVS in compact designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Higher VF (450–520 mV @ 500 mA); same 30 V VR; SOD-523 package (smaller, 1.2 × 0.8 mm). | Lower thermal mass and higher Rth(j-a) (450 K/W) limit continuous current to 0.3 A in same layout. | Select when board area is constrained below 1.25 mm width and peak current <300 mA suffices. |
| PSMN1R0-30YL | MOSFET-based ideal diode (RDS(on) = 1.0 mΩ); requires gate driver; 30 V rating; SO-8 package. | Enables <10 mV drop but adds complexity, BOM count, and ~100 µA quiescent current. | Select only when <0.1 V forward drop is mandatory and design can accommodate active control and extra footprint. |
Compared with RB520S-30T1G and PSMN1R0-30YL, PMEG3005EJ-QX delivers optimal balance of ultra-low VF, AEC-Q101 assurance, and SOD323F manufacturability-making it preferred for production automotive modules where reliability, thermal performance, and solder joint integrity are prioritized over minimal size or theoretical zero-drop operation.

FAQ
What is the maximum continuous forward current for PMEG3005EJ-QX at 85 °C ambient?
At Tamb = 85 °C, the device supports 0.5 A continuous forward current only if mounted on FR4 with 1 cm² cathode pad (Ptot = 830 mW). With standard footprint (Ptot = 360 mW), derating applies: IF(max) ≈ 0.28 A per thermal calculation using Rth(j-a) = 350 K/W and Tj(max) = 150 °C.
Does PMEG3005EJ-QX require a heatsink for 0.5 A operation?
No external heatsink is required. With its 55 K/W junction-to-solder-point thermal resistance and 1 cm² cathode copper pad, the device achieves Tj ≈ 115 °C at 0.5 A and Tamb = 55 °C-well within the 150 °C absolute maximum, provided solder joints meet IPC-A-610 Class 2 standards.
Can PMEG3005EJ-QX replace a standard 1N5819 in automotive designs?
Yes, but with key advantages: 380–430 mV VF (vs. 450–600 mV for 1N5819), AEC-Q101 qualification (1N5819 is not automotive-qualified), and superior surge rating (10 A IFSM vs. 1N5819's 1 A). Layout must accommodate SOD323F instead of DO-41, and thermal relief pads should match Nexperia's recommended footprint.
Is the cathode marking bar visible under automated optical inspection (AOI)?
Yes-the cathode bar is laser-marked as a 0.2 mm wide, high-contrast feature aligned with pin 1 on the SOD323F body. It meets IPC-A-610 Class 2 visibility requirements for AOI systems with ≥10 µm pixel resolution and directional lighting, ensuring reliable automated placement verification.
