Product details
Overview
PMEG4005EPK-QYL from Nexperia is a 40 V, 0.5 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 (530–590 mV at 500 mA), ultra-fast reverse recovery (<2 ns), and AEC-Q101 qualification-enabling use in automotive LED backlighting, DC-DC converters, and reverse polarity protection circuits.
For engineers reviewing the PMEG4005EPK-QYL datasheet, PMEG4005EPK-QYL pinout, PMEG4005EPK-QYL application, or PMEG4005EPK-QYL equivalent, key selection criteria include its 0.37 mm profile, side-wettable flanks for solder joint inspection, 0.4–2 µA reverse leakage at 10 V, and thermal resistance of 150 K/W on FR4 PCB-critical for space-constrained, high-efficiency power designs.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its metal-semiconductor interface enables near-zero reverse recovery charge and eliminates minority-carrier storage delay.
Designed for reflow-only assembly, it features solderable side pads compatible with automated optical inspection (AOI) and X-ray verification. Thermal performance is optimized for ceramic (85 K/W) and FR4 (150 K/W) PCBs, with junction temperature rated to 150 °C and storage range from −65 °C to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports input rails up to 36 V nominal automotive systems with margin. |
| Avg. Forward Current (IF(AV)) | 0.5 A - sustains continuous conduction in compact DC-DC output stages without derating at ≤115 °C ambient. |
| Forward Voltage (VF) | 530–590 mV @ 500 mA - reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency in 1–5 W converters. |
| Reverse Recovery Time (trr) | <2 ns - enables operation beyond 10 MHz switching frequencies with negligible switching loss. |
| Reverse Leakage (IR) | 0.4–2 µA @ 10 V - ensures minimal standby power drain in battery-backed or always-on modules. |

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 (650 mV typ @ 500 mA); TO-220FP package (4.5 mm height); no AEC-Q101 qualification. | Suitable for industrial AC-DC secondary-side rectification where thermal mass matters more than Z-height. | Select when board-level thermal management prioritizes heatsink compatibility over miniaturization. |
| SBM140T3G | Same VF range (540 mV typ), but SOD-123FL package (1.7 mm × 1.3 mm × 1.0 mm); AEC-Q101 qualified; higher IR (5 µA @ 10 V). | Better suited for manual rework or wave-soldered legacy designs due to larger footprint and top-side solderability. | Choose when AOI capability is unavailable or when design requires legacy footprint compatibility over ultra-low profile. |
Compared with RB050M-40TF and SBM140T3G, PMEG4005EPK-QYL offers the lowest profile (0.37 mm), smallest footprint (1.6 × 0.8 mm), and tightest IR spec (0.4 µA), making it optimal for next-gen automotive and portable electronics where space, efficiency, and automated inspection are critical.

FAQ
Is PMEG4005EPK-QYL compatible with lead-free reflow processes?
Yes. The device is qualified for reflow soldering only, with peak temperature tolerance up to 260 °C per JEDEC J-STD-020. Its side-wettable flanks and DFN1608D-2 package are fully compatible with standard lead-free reflow profiles, including ramp-soak-reflow cycles used in automotive electronics manufacturing.
What is the maximum allowable solder point temperature (Tsp) for continuous operation?
The datasheet specifies a maximum solder point temperature (Tsp) of 140 °C for continuous average forward current operation at 0.5 A. Exceeding this limit risks thermal degradation of the die attach and interconnect integrity, especially under high-duty-cycle conditions.
How does the guard ring affect surge performance?
The integrated guard ring redistributes electric field stress away from the junction periphery, increasing the device's ability to withstand repetitive 2 A IFRM and single-event 3 A IFSM surges without avalanche-induced degradation-critical for automotive load-dump and jump-start scenarios.
Can PMEG4005EPK-QYL be used in bidirectional current paths?
No. As a unidirectional Schottky rectifier, it conducts only from anode to cathode. Its reverse breakdown is not specified beyond 40 V VR, and operation in reverse conduction mode will cause permanent damage. Bidirectional functionality requires complementary device pairing or dedicated IC solutions.
