Product details
Overview
PMEG2005BELD-QYL from Nexperia is a 20 V, 0.5 A low forward-voltage Schottky barrier rectifier in an ultra-small DFN1006D-2 (SOD882D) package, featuring integrated guard ring stress protection and side-wettable flanks for automotive-grade solder joint inspection. It delivers VF = 353 mV (typ.) at 500 mA and IR = 28 µA (typ.) at 10 V, enabling high-efficiency low-voltage DC-to-DC conversion in space-constrained mobile power rails.
For engineers reviewing the PMEG2005BELD-QYL datasheet, PMEG2005BELD-QYL pinout, PMEG2005BELD-QYL application, or PMEG2005BELD-QYL equivalent, key selection criteria include its AEC-Q101 qualification, 0.37 mm typical package height, 1.6 ns reverse recovery time, and thermal resistance of 170 K/W (junction-to-solder-point on FR4), critical for thermally dense automotive and portable electronics designs.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress, ensuring stable operation up to 150 °C junction temperature. Its low VF and ultra-fast trr = 1.6 ns support high-frequency switching in synchronous buck converters and reverse polarity protection circuits.
The device is optimized for reflow-only assembly on FR4 PCBs with standard or extended cathode pads, delivering Ptot = 735 mW (typ.) at Tamb ≤ 25 °C and Rth(j-sp) = 25 K/W when soldered to the cathode tab - a design choice that directly enables compact, high-reliability power stage layouts in automotive body control modules and LED backlight drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability for 12 V automotive systems and 5 V/3.3 V logic rail protection. |
| Average Forward Current (IF(AV)) | 0.5 A - Sustained DC current handling on FR4 PCB with standard footprint at Tamb ≤ 115 °C. |
| Forward Voltage (VF) | 353 mV (typ.) at 500 mA - Reduces conduction loss by >40% vs. standard Schottkys, improving efficiency in battery-powered devices. |
| Reverse Current (IR) | 28 µA (typ.) at 10 V, 25 °C - Minimizes standby leakage in always-on power domains like CAN transceiver bias rails. |
| Reverse Recovery Time (trr) | 1.6 ns - Enables clean switching at >10 MHz frequencies without voltage overshoot in high-speed DC-DC controllers. |
| Thermal Resistance (Rth(j-sp)) | 25 K/W - Low junction-to-solder-point resistance allows direct thermal coupling to copper pour, simplifying thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | 30 V VR, 200 mA IF(AV), VF = 370 mV @ 100 mA, SOD-523 package (1.2 × 0.8 mm) | Lower current rating and larger footprint; not AEC-Q101 qualified | Select only for non-automotive, low-current (<200 mA), cost-sensitive consumer applications. |
| NSR0230HT1G | 30 V VR, 200 mA IF(AV), VF = 450 mV @ 200 mA, SOD-123FL package (2.7 × 1.6 mm) | Higher VF, larger size, no side-wettable flanks, no AEC-Q101 qualification | Use only where board space and AOI are not constraints, and automotive compliance is unnecessary. |

FAQ
Is PMEG2005BELD-QYL compatible with lead-free reflow soldering processes?
Yes - the device is qualified exclusively for reflow soldering per J-STD-020, with peak temperatures up to 260 °C. Its DFN1006D-2 package supports standard Pb-free reflow profiles, and side-wettable flanks enable post-reflow AOI verification without X-ray. Hand soldering or wave soldering is not recommended.
What is the maximum ambient temperature for continuous 0.5 A operation?
On a standard FR4 PCB with single-sided copper, the PMEG2005BELD-QYL supports 0.5 A average forward current up to Tamb = 115 °C (δ = 0.5, f = 20 kHz square wave). At Tamb = 25 °C, it sustains 0.5 A with Tj ≤ 140 °C; derating is required above 115 °C ambient per Figure 10 in the datasheet.
Does the cathode marking bar indicate polarity during PCB layout?
Yes - the bar on the top surface identifies Pin 1 (cathode). Correct orientation is critical: the cathode must connect to the more positive potential in reverse polarity protection, or to the output node in freewheeling configurations. Misorientation causes immediate short-circuit failure under forward bias.
How does the guard ring affect voltage derating in transient conditions?
The integrated guard ring suppresses edge avalanche, allowing the device to maintain rated 20 V VR under repetitive 100 ns transients up to 30 V without degradation. This eliminates need for external TVS clamping in 12 V automotive load-dump scenarios where peak voltages reach 25–30 V, reducing BOM count and board area.
