Product details
Overview
PMEG4020EPK-QYL from Nexperia is a 40 V, 2 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-small leadless DFN1608D-2 (SOD1608) package. It delivers low forward voltage (585–660 mV at 2 A), ultra-fast reverse recovery (<4 ns), and AEC-Q101 qualification-optimized for automotive DC/DC converters and LED backlighting where efficiency and space constraints are critical.
For engineers reviewing the PMEG4020EPK-QYL datasheet, PMEG4020EPK-QYL pinout, PMEG4020EPK-QYL application, or PMEG4020EPK-QYL equivalent, key selection criteria include its 0.37 mm profile, side-wettable flanks for solder joint inspection, 150 °C junction rating, and verified performance under pulsed 20 kHz square-wave conditions per AEC-Q101 stress testing.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient overvoltage stress. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without minority-carrier storage delay.
The device operates with zero reverse recovery charge (Qrr ≈ 0), eliminating switching losses in high-frequency topologies. Thermal resistance to solder point is as low as 20 K/W when mounted on ceramic PCBs, supporting stable operation up to 150 °C junction temperature in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability for 12 V/24 V automotive rail protection and buck converter freewheeling. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC or pulsed current handling on FR4 PCB with standard footprint at ≤25 °C ambient. |
| Forward Voltage (VF) | 585–660 mV @ 2 A - Enables <1.3 W conduction loss at full load, critical for thermal budget in sealed modules. |
| Reverse Recovery Time (trr) | <4 ns - Eliminates switching tail current, allowing >1 MHz operation in synchronous rectification and boost converters. |
| Reverse Current (IR) | 1–5 µA @ 10 V - Minimizes standby leakage in battery-powered systems like infotainment displays. |
| Thermal Resistance (Rth(j-sp)) | 20 K/W - Enables direct thermal coupling to copper pour via cathode-side wettable flanks for efficient heat extraction. |
| Package Height | 0.37 mm typ. - Fits beneath 0.4 mm board-to-board connectors and enables ultra-thin display bezel designs. |
Pinout & Package
Encapsulated in a leadless DFN1608D-2 (SOD1608) surface-mount package measuring 1.6 mm × 0.8 mm × 0.37 mm, with visible and solderable side pads for automated optical inspection (AOI) and IPC-compliant reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; marked by bar on top surface; connects to ground or low-side return path; primary thermal path to PCB via side-wettable flank. |
| 2 (A) | Anode | Current entry terminal; connects to input rail or switch node; electrically isolated from cathode pad; no thermal function beyond conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including engine control units and ADAS power supplies. |
| Solderable side pads | Enables automated X-ray and AOI verification of solder fillet integrity-critical for zero-defect automotive manufacturing. |
| Integrated guard ring | Suppresses electric field crowding at die edges, improving long-term reliability under repetitive surge stress (e.g., load dump). |
| Ultra-low VF at 2 A | Reduces conduction loss by ≥25% vs. comparable 40 V Schottkys, directly extending battery runtime in portable infotainment systems. |
| 0.37 mm profile | Permits placement under mechanical shields and near flex-circuit interfaces in space-constrained telematics modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EDH04-M3/86A | Same 40 V VR, but IF(AV) = 1.5 A; VF = 620 mV @ 1.5 A; TO-277 package (3.1 mm × 1.7 mm × 1.1 mm). | Larger footprint and 3× height limit use in ultra-thin displays; lacks AEC-Q101 certification. | Select only if board space allows larger package and automotive qualification is not required. |
| ON Semiconductor NSR20F40NXT5G | 40 V VR, 2 A IF(AV); VF = 590 mV @ 2 A; same DFN1608 package; AEC-Q101 qualified. | Identical form factor and thermal specs; slightly lower IR (0.5 µA @ 10 V) but no guard ring. | Prefer for cost-sensitive non-safety-critical automotive modules where edge reliability margin is less critical. |
Compared with VS-2EDH04-M3/86A, PMEG4020EPK-QYL saves >60% board area and meets automotive stress requirements; versus NSR20F40NXT5G, its guard ring provides superior surge immunity in load-dump-prone environments like body control modules.

FAQ
Is PMEG4020EPK-QYL compatible with lead-free reflow profiles?
Yes. The device is qualified for JEDEC J-STD-020D Level 3 moisture sensitivity and supports peak reflow temperatures up to 260 °C. Its side-wettable flanks are designed for standard SnAgCu paste and 240–260 °C peak profiles with 60-second dwell above 220 °C.
What is the maximum allowable solder joint temperature during rework?
The maximum localized solder joint temperature must not exceed 300 °C for durations ≤10 seconds. Exceeding this risks delamination of the die attach or degradation of the guard ring structure, particularly at the cathode edge termination.
Does the marking "0001 0000" correspond to date code or lot traceability?
No. Per Nexperia documentation, "0001 0000" is a fixed 8-digit alphanumeric code identifying the PMEG4020EPK-Q variant within the DFN1608D-2 family; it is not a date or lot code. Full traceability requires the reel label's 12-digit lot number.
Can PMEG4020EPK-QYL replace older PMEG4020CPK in existing designs?
Yes, with identical footprint and electrical specs, but PMEG4020EPK-QYL adds AEC-Q101 qualification and improved thermal resistance (20 K/W vs. 25 K/W to solder point). No layout change is needed, though automotive validation testing should be repeated per ISO/TS 16949 requirements.
