Product details
Overview
PMEG2005EPK-QYL from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection in space-constrained automotive and portable electronics. It delivers 0.5 A average forward current at ≤410 mV forward voltage (IF = 500 mA, Tj = 25 °C), supports 20 V reverse voltage, exhibits ultra-fast 3 ns reverse recovery time, and is qualified to AEC-Q101.
For engineers reviewing the PMEG2005EPK-QYL datasheet, PMEG2005EPK-QYL pinout, PMEG2005EPK-QYL application, or PMEG2005EPK-QYL equivalent, key selection criteria include its ultra-low VF for minimal conduction loss, side-wettable DFN1608D-2 package for automated optical inspection, thermal performance on FR4 vs. ceramic PCBs, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This Schottky diode uses a planar junction structure with an integrated guard ring to suppress edge breakdown and improve robustness against transient overvoltage and ESD stress. Its low barrier height enables sub-410 mV forward voltage at 500 mA while maintaining low reverse leakage (≤130 µA at VR = 10 V, Tj = 25 °C).
The device operates with near-zero reverse recovery charge due to majority-carrier conduction, enabling clean switching in high-frequency SMPS and LED backlight circuits. Thermal resistance varies significantly by PCB construction: Rth(j-a) = 320 K/W on standard FR4, but drops to 85 K/W on ceramic Al₂O₃ - a critical design consideration for power density optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ IF = 500 mA | 360–410 mV - Enables ≥92% efficiency in 3.3 V → 1.8 V buck converters at 500 mA load |
| VR | 20 V - Supports input rails up to 16 V DC with 20% margin for automotive transients |
| trr | 3 ns - Eliminates switching node ringing in >1 MHz DC/DC controllers without snubbers |
| IR @ VR = 10 V | 30–130 µA - Minimizes standby power loss in battery-powered mobile backlight systems |
| Package | DFN1608D-2 (SOD1608), 1.6 × 0.8 × 0.37 mm - Enables <0.8 mm² board area; side-wettable flanks support AOI-capable reflow |
| AEC-Q101 Qualified | Yes - Validated for automotive temperature range (−40 °C to +150 °C junction), including humidity, temperature cycling, and HTRB |
Pinout & Package
Encapsulated in a leadless, ultra-small DFN1608D-2 (SOD1608) surface-mount plastic package with solderable side pads and typical height of 0.37 mm. The cathode is marked by a visible bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to output/load side in forward-biased rectification; marking bar identifies this terminal |
| 2 (A) | Anode | Connected to input/source side; forms low-VF conduction path when biased positive relative to cathode |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown during load dump or ISO 7637-2 pulse 5a, improving reliability in automotive 12 V systems |
| Solderable side pads | Enables automated optical inspection (AOI) of solder joint quality - critical for zero-defect automotive manufacturing |
| Ultra-low profile (0.37 mm) | Permits stacking under thin-film shields or beneath compact camera modules in smartphones and ADAS sensors |
| Low thermal resistance to solder point | Rth(j-sp) = 20 K/W - Direct thermal path from junction to cathode pad reduces localized heating in high-pulse-current LED drivers |
Applications
| Automotive Infotainment Power Rails | Smartphone LED Backlight Driver |
|---|---|

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 @ 500 mA), larger SOD-123FL package (3.5 × 1.6 mm), no AEC-Q101 qualification | Limited to consumer-grade portable devices; unsuitable for automotive under-hood placement | Select only if cost sensitivity outweighs size and qualification requirements |
| SS12-A | Lower IF(AV) (200 mA), higher trr (5 ns), TO-277 package (3.5 × 1.3 mm), no side-wettable flanks | Inadequate for 500 mA continuous loads; incompatible with AOI-based production lines | Use only in legacy designs where footprint compatibility with TO-277 is mandatory |
Compared with RB050M-40TF and SS12-A, PMEG2005EPK-QYL provides the smallest footprint, lowest conduction loss, and only AEC-Q101-qualified option - making it the sole choice for new automotive and high-density portable designs requiring verified reliability and manufacturability.

FAQ
What is the maximum allowable solder point temperature for PMEG2005EPK-QYL during reflow?
The datasheet specifies Tsp ≤ 140 °C for average forward current derating and Tsp ≤ 135 °C for peak forward current handling. Exceeding 140 °C risks permanent degradation of the Schottky junction and guard ring integrity. Reflow profiles must maintain peak solder point temperature ≤135 °C for 10 seconds maximum, per Figure 13 and Table 5.
Can PMEG2005EPK-QYL be used in reverse-biased ESD protection configurations?
No - this device is not rated or characterized for ESD clamping. Its guard ring improves surge robustness but does not provide defined IEC 61000-4-2 or ISO 10605 protection parameters. For ESD protection, use dedicated TVS diodes such as Nexperia PESD5V0S1BA; PMEG2005EPK-QYL is intended solely for rectification and polarity protection.
How does thermal performance differ between FR4 and ceramic PCB mounting?
On standard FR4, Rth(j-a) is 320 K/W; with a 1 cm² cathode pad, it improves to 150 K/W. On ceramic Al₂O₃, it reaches 85 K/W. This means at 0.5 A and 360 mV VF (180 mW dissipation), junction temperature rise is ~58 °C on FR4 vs. ~15 °C on ceramic - directly impacting lifetime and derating in thermally constrained enclosures.
Is the marking code "1000 0000" unique to PMEG2005EPK-QYL?
Yes - per Table 4 and Figure 1, "1000 0000" is the binary marking code assigned exclusively to PMEG2005EPK-QYL in the DFN1608D-2 package. The cathode bar orientation and reading direction are standardized; no other Nexperia Schottky rectifier shares this exact marking sequence in this package variant.
