Product details
Overview
PMEG3005EH-QX from Nexperia is a 30 V, 0.5 A automotive-qualified Schottky barrier rectifier in SOD123F package, featuring 380–430 mV forward voltage at 500 mA, integrated guard ring for stress protection, and optimized for low-voltage DC-to-DC conversion in engine control units.
For engineers reviewing the PMEG3005EH-QX datasheet, PMEG3005EH-QX pinout, PMEG3005EH-QX application, or PMEG3005EH-QX equivalent, this device is selected for reverse polarity protection, high-efficiency buck converters, and automotive body electronics where low VF and AEC-Q101 compliance are mandatory.
Technical Context
This MEGA Schottky rectifier uses planar construction with an integrated guard ring to suppress edge breakdown under high dv/dt or thermal stress-critical for automotive transients. Its low VF stems from optimized metal-semiconductor junction design, not series resistance reduction alone.
Thermal performance is defined by two Rth(j-a) values (330 K/W standard footprint; 150 K/W enhanced cathode pad), reflecting real-world PCB layout dependency. Reverse leakage remains below 150 µA at 30 V and 25 °C, enabling stable operation in battery-sensed circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Reverse Voltage | 30 V - supports 24 V automotive systems with margin against load dump spikes up to ISO 7637-2 Pulse 5a. |
| Forward Current (DC) | 0.5 A - rated for continuous conduction in compact 5–12 V DC/DC outputs without forced cooling. |
| Forward Voltage | 380–430 mV @ 500 mA - reduces conduction loss by >40% vs. standard Schottkys, improving efficiency in <1 W power rails. |
| Reverse Leakage | ≤150 µA @ 30 V - ensures minimal standby current in always-on vehicle modules (e.g., CAN wake-up circuits). |
| Junction Temp Limit | 150 °C - enables operation in under-hood environments (e.g., transmission control units) with derating per thermal data. |
| Package | SOD123F - 2.6 × 1.6 × 1.1 mm surface-mount outline with flat leads for reliable reflow and automated optical inspection. |
| AEC-Q101 Qualified | Yes - qualified for automotive discrete semiconductors per stress test requirements including HTRB, HTGB, and temperature cycling. |
Pinout & Package
Encapsulated in a compact SOD123F plastic SMD package (2.6 mm × 1.6 mm × 1.1 mm), with flat leads and cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode (K) | Connected to system ground or return path; marking bar identifies this terminal for correct orientation during placement. |
| 2 | Anode (A) | Input side of rectification path; accepts positive input voltage in forward-biased configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 380–430 mV at 500 mA enables ≥92% efficiency in 5 V → 3.3 V buck stages at light loads. |
| Integrated guard ring | Suppresses edge-related avalanche and improves long-term reliability under repetitive surge conditions (e.g., ISO 16750-2). |
| AEC-Q101 qualification | Validated for automotive use across temperature (-40 °C to +150 °C), vibration, and humidity stress profiles. |
| Low capacitance | 55–70 pF at 1 V reverse bias minimizes switching node ringing in high-frequency (>500 kHz) synchronous rectifiers. |
Applications
| Engine Control Unit Power Rail | Automotive Infotainment USB Port |
|---|---|
Use Scenario: Provides reverse polarity protection on 12 V input to MCU power management ICs. IC Role / Device Role / Timing Role: Unidirectional blocking diode in series with input rail, preventing damage from battery misconnection. Use Value: Low VF avoids >0.4 V drop that would compromise 5 V LDO headroom; AEC-Q101 ensures field reliability over 15-year vehicle life. |
Use Scenario: Isolates dual-power sources (USB host + local battery) in rear-seat entertainment systems. IC Role / Device Role / Timing Role: OR-ing diode enabling seamless source switchover without software intervention. Use Value: 150 µA max IR prevents battery drain during sleep mode; SOD123F footprint fits tight space behind display bezel. |
| Body Control Module DC/DC Output | ADAS Camera Power Sequencing |
Use Scenario: Output rectifier in 24 V → 5 V buck converter supplying microcontroller and CAN transceiver. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in low-cost non-synchronous designs. Use Value: 380 mV VF cuts conduction loss by 65% vs. 1N5819, reducing thermal load on 2-layer PCB without heatsink. |
Use Scenario: Reverse voltage clamp on 3.3 V imaging sensor supply line exposed to ESD events. IC Role / Device Role / Timing Role: Low-capacitance transient shunt protecting image sensor I/O pins during hot-plug. Use Value: 70 pF capacitance avoids signal integrity degradation on 24 MHz pixel clock lines; 150 °C Tj rating survives camera housing temperatures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS0530Z | Same 30 V / 0.5 A rating but VF = 450–500 mV; no AEC-Q101 qualification; TO-236AB package (larger than SOD123F). | Acceptable for industrial DC/DC where automotive qualification is unnecessary and board space allows. | Select when cost is prioritized over automotive compliance and thermal density. |
| ON Semi NSR0530P2T5G | VF = 410–460 mV at 500 mA; AEC-Q101 qualified; same SOD123F package; IR = 200 µA at 30 V (50 µA higher). | Higher leakage may impact ultra-low-power always-on nodes (e.g., remote keyless entry receivers). | Prefer when sourcing diversity is required and leakage sensitivity is moderate. |
Compared with STPS0530Z and NSR0530P2T5G, PMEG3005EH-QX delivers the lowest VF in its class with guaranteed AEC-Q101 compliance and the smallest footprint-making it optimal for space-constrained, thermally sensitive automotive power rails where efficiency and qualification are non-negotiable.

FAQ
Is PMEG3005EH-QX suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. It replaces conventional diodes in non-synchronous buck or flyback topologies. Its low VF and fast recovery (<10 ns) make it ideal for high-frequency (up to 1 MHz) hard-switched applications, but gate drive signals cannot be applied.
What is the maximum allowable PCB copper area for the cathode pad to achieve 150 K/W Rth(j-sp)?
The datasheet specifies 1 cm² tin-plated copper area on a single-sided FR4 board for the cathode pad to reach the 150 K/W Rth(j-sp) value. This area must be unbroken, directly connected to the cathode terminal, and free of solder mask over the entire 10 mm × 10 mm region.
Does the "Q" suffix in PMEG3005EH-QX indicate AEC-Q200 qualification?
No-the "Q" denotes AEC-Q101 qualification for discrete semiconductors, not AEC-Q200 (which applies to passive components). The device meets all stress tests in AEC-Q101 Rev G, including HTRB, HTGB, and ESD-HBM ≥2 kV, as confirmed in Section 11 of the datasheet.
Can PMEG3005EH-QX be used in 48 V mild-hybrid systems?
No-its 30 V maximum reverse voltage provides insufficient margin for 48 V nominal systems, which experience transients exceeding 60 V (e.g., ISO 16750-2 Pulse 5a). For 48 V applications, Nexperia's PMEG6020EH-Q (60 V rating) or equivalent is required.
