Product details
Overview
PMEG2005AELD-QYL from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 20 V reverse voltage and 0.5 A average forward current, featuring low 365–440 mV forward voltage at 500 mA and qualified to AEC-Q101 for automotive power rail protection in compact DC-DC converters.
For engineers reviewing the PMEG2005AELD-QYL datasheet, PMEG2005AELD-QYL pinout, PMEG2005AELD-QYL application, or PMEG2005AELD-QYL equivalent, key selection criteria include ultra-low VF performance under pulsed 500 mA load, thermal resistance to solder point (50 K/W), side-wettable flanks for automated optical inspection, and SOD882D package compatibility with high-density automotive PCB layouts.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient overvoltage stress. Its low barrier height enables fast switching (6 ns trr) and minimal reverse recovery loss in high-frequency SMPS topologies.
The device operates with junction temperatures up to 150 °C and is characterized for mounting on FR4 (1 cm² cathode pad) and ceramic (Al₂O₃) substrates, delivering 0.5 A IF(AV) at 85 °C ambient when mounted on standard FR4 - enabled by low Rth(j-sp) of 50 K/W to the cathode solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - maximum blocking capability for 12 V automotive rail clamping and reverse polarity protection. |
| Average Forward Current (IF(AV)) | 0.5 A - continuous DC or square-wave (δ = 0.5, f = 20 kHz) conduction capacity on FR4 PCB with 1 cm² cathode pad. |
| Forward Voltage (VF) | 365–440 mV @ 500 mA - enables <150 mW conduction loss at full rated current, critical for thermally constrained modules. |
| Reverse Current (IR) | 300–600 µA @ 10 V - low leakage preserves efficiency in battery-backed and always-on low-power circuits. |
| Reverse Recovery Time (trr) | 6 ns - supports >10 MHz switching frequencies without significant commutation loss in synchronous rectifiers. |
| Diode Capacitance (Cd) | 19–25 pF @ 1 V - minimizes capacitive loading and EMI in high-speed gate-drive and signal-path applications. |
| Thermal Resistance (Rth(j-sp)) | 50 K/W - enables direct thermal coupling to PCB copper, allowing high-current operation without external heatsinking. |
Pinout & Package
Encapsulated in the DFN1006D-2 (SOD882D) leadless ultra-small surface-mount package (1.0 × 0.6 × 0.4 mm, 0.65 mm pitch), with visible and solderable side pads for automated optical inspection and reliable reflow joint formation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; marked with cathode bar on top surface; connected to large-area PCB copper pad for thermal and current handling. |
| 2 (A) | Anode | Current entry terminal; side-wettable flank enables solder fillet visibility and IPC-A-610 Class 2/3 process verification. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood environments (−40 °C to +150 °C junction), including temperature cycling, HTRB, and ESD testing. |
| Guard ring integration | Suppresses electric field crowding at die edges, improving VR consistency and long-term reliability under repetitive surge stress. |
| Side-wettable flanks (SWF) | Enables automated X-ray and AOI inspection of solder joints without requiring cross-sectioning or destructive analysis. |
| Ultra-low profile (0.37 mm typ.) | Supports co-placement with thin-profile inductors and stacked power modules in space-constrained ADAS and infotainment PCBs. |
| Low thermal resistance to solder point | 50 K/W path from junction to cathode solder interface allows efficient heat transfer into PCB plane, reducing local hot spots. |
Applications
| Automotive Power Rail Protection | High-Frequency DC-DC Converter Output Rectification |
|---|---|
|
Use Scenario: Reverse polarity protection circuit on 12 V battery input to body control module (BCM). IC Role / Device Role / Timing Role: Unidirectional current blocking element placed in series with main power feed; conducts only during correct polarity connection. Use Value: 440 mV VF limits voltage drop to <0.5 V at 500 mA, preserving headroom for downstream LDOs while dissipating <220 mW. |
Use Scenario: Secondary-side rectifier in 2 MHz buck converter powering automotive camera sensor. IC Role / Device Role / Timing Role: Synchronous rectification replacement in non-controlled topology; handles 500 mA average output current. Use Value: 6 ns trr and 25 pF capacitance minimize switching loss and ringing, enabling stable regulation without snubbers. |
| Low-Power IoT Node Power Management | USB-C Port Protection Circuit |
|
Use Scenario: Input OR-ing diode in dual-supply (battery + USB) wearable health monitor. IC Role / Device Role / Timing Role: Prevents backfeed between sources; selected for lowest possible forward drop to extend battery runtime. Use Value: 365 mV VF at 100 mA reduces conduction loss by >40% vs. standard Schottky alternatives, extending discharge time by ~12%. |
Use Scenario: Overvoltage clamp and reverse-current block in USB-C receptacle ESD protection array. IC Role / Device Role / Timing Role: Standby-blocking diode in parallel with TVS; activated only during fault conditions or incorrect cable insertion. Use Value: 20 V VR rating matches USB PD 3.0 max bus voltage; 600 µA IR at 10 V ensures negligible standby current drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (490 mV @ 500 mA), larger SOD-123FL package (1.7 × 1.3 × 0.9 mm), no AEC-Q101 qualification. | Not suitable for automotive underhood use; limited to consumer-grade portable electronics. | Select only if board space and thermal budget allow larger footprint and higher conduction loss is acceptable. |
| SBM0520 | Same SOD882D package, but VF = 450 mV @ 500 mA and IR = 1000 µA @ 10 V; not AEC-Q101 qualified. | Lacks automotive stress test validation; higher leakage may impact battery-critical always-on functions. | Acceptable for cost-sensitive industrial DC-DC where AEC compliance is not required and leakage tolerance >600 µA exists. |
Compared with RB050M-30 and SBM0520, PMEG2005AELD-QYL delivers the lowest VF in its class within an AEC-Q101-qualified SOD882D package, making it the preferred choice for space-constrained, thermally demanding automotive power nodes where conduction loss and reliability are jointly critical.

FAQ
What is the maximum allowable solder point temperature for PMEG2005AELD-QYL during reflow?
The device is rated for a maximum solder point temperature (Tsp) of 130 °C under square-wave pulse conditions (δ = 0.5, f = 20 kHz). Reflow profiles must ensure peak Tsp does not exceed this limit to maintain 0.5 A IF(AV) derating integrity and avoid intermetallic degradation at the cathode interface.
Does PMEG2005AELD-QYL support wave soldering?
No - the SOD882D package is designed exclusively for reflow soldering. Wave soldering is incompatible due to the absence of through-hole leads and risk of solder bridging across side-wettable flanks; recommended process is lead-free reflow per J-STD-020, with peak temperature ≤ 260 °C.
How does the guard ring affect voltage derating in transient conditions?
The integrated guard ring improves edge termination robustness, allowing the device to sustain 20 V VR continuously and withstand short-duration transients up to 25 V without premature avalanche - verified per AEC-Q101 HBM (≥8 kV) and CDM (≥1 kV) tests.
Can PMEG2005AELD-QYL be used in bidirectional current paths?
No - it is a unidirectional Schottky rectifier. The anode-to-cathode configuration only permits forward conduction; reverse bias blocks current up to 20 V. Bidirectional operation would require complementary devices or a dedicated bidirectional switch IC.
