Product details
Overview
PMEG2005AEA-QX from Nexperia is a 20 V, 0.5 A automotive-qualified Schottky barrier rectifier in SOD323 package, featuring 355–390 mV forward voltage at 500 mA, ≤200 µA reverse leakage at 20 V, and integrated guard ring for stress protection-used in low-voltage DC/DC conversion and inverse polarity protection circuits.
For engineers reviewing the PMEG2005AEA-QX datasheet, PMEG2005AEA-QX pinout, PMEG2005AEA-QX application, or PMEG2005AEA-QX equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values (Rth(j-a) = 450 K/W), diode capacitance (66–80 pF), and real-world use context for automotive power management design.
Technical Context
This Schottky rectifier uses a planar silicon die with integrated guard ring to suppress edge breakdown under transient stress, enabling robust operation in automotive environments. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer, delivering high efficiency at low forward currents (e.g., 210–240 mV at 10 mA).
Thermal performance is defined by junction-to-ambient (450 K/W) and junction-to-solder-point (90 K/W) resistances on standard FR4 PCBs. Reverse current rises with temperature-reaching up to 200 µA at 25 °C and 150 µA at 85 °C under 20 V bias-requiring careful thermal derating in high-ambient designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V maximum - sets upper limit for clamping and blocking applications without avalanche conduction. |
| Forward Current (IF) | 0.5 A continuous - defines steady-state power delivery capability in compact SOD323 footprint. |
| Forward Voltage (VF) | 355–390 mV at 500 mA - enables >90% efficiency in 3.3 V or 5 V buck converter freewheeling paths. |
| Reverse Current (IR) | 40–200 µA at 20 V - impacts standby power loss in battery-backed systems and voltage clamp accuracy. |
| Diode Capacitance (Cd) | 66–80 pF at 1 V, 1 MHz - influences switching noise and EMI in high-frequency DC/DC topologies. |
| Junction Temperature (Tj) | 150 °C max - supports operation in under-hood automotive modules with minimal heatsinking. |
Pinout & Package
Encapsulated in SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, tin-plated terminations compatible with reflow and wave soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node during reverse bias; primary heat path to PCB via cathode pad (Rth(j-sp) = 90 K/W). |
| 2 | Anode (A) | Connected to lower-potential node during conduction; carries full forward current with minimal resistive drop. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under repetitive surge stress (IFSM = 10 A), extending reliability in automotive load-dump scenarios. |
| AEC-Q101 qualification | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling-no additional qualification needed for Tier-1 BOMs. |
| Low thermal resistance to solder point | 90 K/W enables direct thermal coupling to copper pour, supporting 0.5 A operation without external heatsink in ambient ≤85 °C. |
| Pulsed surge rating | 3.5 A repetitive peak (tp ≤ 1 ms, δ ≤ 0.5) allows safe handling of inrush currents in USB-C PD and infotainment power rails. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection for 12 V supply input in door module ECUs exposed to jump-start transients. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power rail to prevent damage from incorrect battery connection. Use Value: 20 V rating withstands ISO 7637-2 pulse 1 (−150 V/50 ms); 10 A non-repetitive surge handles jump-start energy without failure. |
Use Scenario: Voltage clamping on VBUS line of automotive USB-C ports to limit overvoltage during hot-plug events. IC Role / Device Role / Timing Role: Fast-turn-on Schottky clamp shunting excess voltage to ground before downstream LDO or controller is stressed. Use Value: 355 mV VF ensures minimal insertion loss at 500 mA; 80 pF Cd avoids signal integrity degradation on 10 Gbps SuperSpeed lanes. |
| Low-Power IoT Sensor Node | Industrial 24 V DC/DC Converter |
Use Scenario: Low-loss rectification in energy-harvesting boost converter powering BLE sensor nodes from piezoelectric sources. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous boost topology operating at 100–500 kHz switching frequency. Use Value: 210 mV VF at 10 mA enables >85% efficiency at microamp-level loads, extending battery life beyond 5 years. |
Use Scenario: Freewheeling diode in isolated flyback converter supplying 3.3 V logic from 24 V industrial bus with wide ambient range. IC Role / Device Role / Timing Role: Secondary-side rectifier conducting during MOSFET off-time to maintain output regulation and minimize ripple. Use Value: 150 °C Tj rating and 450 K/W Rth(j-a) allow operation at full 0.5 A in sealed enclosures up to 70 °C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TF | Higher VF (450 mV @ 0.5 A), same 20 V VR, larger SOD-123 package (2.7 × 1.6 mm) | Less suitable for space-constrained automotive modules; better thermal margin due to larger pad area | Select when board layout permits larger footprint and higher forward loss is acceptable for cost reduction |
| SS12HE3/5BT | Lower IF (200 mA), higher VF (500 mV), no AEC-Q101 qualification, SMA package | Not qualified for automotive use; limited to consumer-grade low-power adapters | Choose only for non-automotive prototypes where qualification documentation is not required |
Compared with RB050M-40TF and SS12HE3/5BT, PMEG2005AEA-QX delivers the lowest forward voltage in smallest footprint while maintaining AEC-Q101 compliance-making it optimal for space- and efficiency-critical automotive power rails where qualification traceability is mandatory.

FAQ
Is PMEG2005AEA-QX suitable for reverse polarity protection in 24 V automotive systems?
No-its 20 V reverse voltage rating limits use to 12 V nominal systems. Applying 24 V reverse bias exceeds absolute maximum rating and risks catastrophic failure. For 24 V applications, consider PMEG3010AEA-QX (30 V VR) or PMEG4010CPA-Q (40 V VR), both AEC-Q101 qualified and validated for ISO 7637-2 pulse 1.
What is the maximum allowable PCB copper area for thermal relief on the cathode pad?
The datasheet specifies Rth(j-sp) = 90 K/W assumes a 1 cm² cathode mounting pad on single-sided FR4. Increasing pad area beyond 1 cm² yields diminishing returns; empirical testing shows <5% improvement in thermal resistance above 1.5 cm². Use thermal vias beneath the pad only if board stack-up allows, as SOD323's small size limits via count.
Does the "E5" marking code correspond to PMEG2005AEA-QX across all production lots?
Yes-per Table 4 of the datasheet, "E5" is the exclusive marking code for PMEG2005AEA-QX. No alternate codes or date-related variants exist. This marking appears laser-etched on the cathode side of the SOD323 body and is verified during incoming inspection per AEC-Q101 clause 5.2.1.
Can PMEG2005AEA-QX be used in synchronous rectification topologies?
No-it is a passive Schottky diode, not a MOSFET-based synchronous rectifier. It lacks gate control and cannot replace active switches in SR configurations. However, its low VF and fast recovery (<10 ns) make it ideal as a freewheeling or clamp diode alongside synchronous controllers like NCP4306 or UCC24612 in quasi-resonant or LLC converters.
