Product details
Overview
PMEG2010BELD from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage DC-to-DC conversion and reverse polarity protection. It delivers 1 A average forward current at ≤490 mV forward voltage (IF = 1 A), supports 20 V reverse voltage, and operates in ultra-small DFN1006D-2 (SOD882D) package with solderable side pads.
For engineers reviewing the PMEG2010BELD datasheet, PMEG2010BELD pinout, PMEG2010BELD application, or PMEG2010BELD equivalent, key selection criteria include low VF performance under pulsed 1 A load, thermal resistance to solder point (25 K/W), ultra-thin 0.37 mm profile, and compatibility with reflow-only assembly on FR4 or ceramic PCBs.
Technical Context
This Schottky diode uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low forward voltage stems from optimized metal-semiconductor interface design, enabling high efficiency in space-constrained power rails.
Thermal performance is defined relative to mounting configuration: Rth(j-sp) = 25 K/W (cathode solder point), with junction-to-ambient resistance varying from 110 K/W (ceramic PCB) to 340 K/W (FR4, standard footprint). Reverse recovery time is 1.6 ns - typical for Schottky devices - supporting ultra-high-speed switching without minority-carrier tail current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 1 A | 428–490 mV - enables ≥92% efficiency in 3.3 V buck converters at full load |
| VR | 20 V - suitable for 12 V input rails with 50% safety margin against transients |
| IF(AV) | 1 A - rated for continuous operation at 130 °C solder point temperature |
| trr | 1.6 ns - eliminates switching losses in >1 MHz DC-DC topologies |
| Cd @ 1 V | 31–40 pF - minimizes capacitive loading on high-frequency gate drivers or signal paths |
| IR @ 20 V | 87–200 µA - low leakage preserves battery life in always-on low-power systems |
| Rth(j-sp) | 25 K/W - enables direct thermal coupling to PCB copper for passive cooling in compact layouts |
Pinout & Package
Encapsulated in leadless DFN1006D-2 (SOD882D) package: 1.0 mm × 0.6 mm × 0.37 mm body height, side-wettable flanks for automated optical inspection, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output node for rectified current; connects to ground or return path; marked by cathode bar |
| 2 | Anode (A) | Input node for unregulated supply; accepts up to 20 V reverse bias during freewheeling |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under voltage transients, improving long-term reliability in noisy automotive/industrial environments |
| Solderable side pads | Enables AOI-compatible reflow inspection and robust mechanical anchoring on fine-pitch PCBs |
| Ultra-low profile (0.37 mm) | Permits use in <1 mm total stack-up applications such as slim mobile displays and wearables |
| Reflow-only assembly | Eliminates need for wave or hand-soldering; compatible with standard lead-free reflow profiles (J-STD-020) |
| Low thermal resistance to solder point | 25 K/W allows direct heat transfer from junction to PCB copper, reducing local hot spots in dense layouts |
Applications
| Mobile LED Backlighting | USB-C Power Path Protection |
|---|---|
Use Scenario: Driving white LEDs from 3.3 V or 5 V boost converter output in smartphones and tablets. IC Role / Device Role / Timing Role: Low-loss freewheeling diode in boost inductor path; handles 1 A peak current pulses at >1 MHz switching frequency. Use Value: 428 mV VF reduces power loss by 300 mW vs. standard Schottky alternatives, extending battery runtime by ~4% in active display mode. |
Use Scenario: Reverse polarity and backfeed protection between dual USB-C ports sharing a common VBUS rail. IC Role / Device Role / Timing Role: Unidirectional blocking element placed in series with each port's VBUS line. Use Value: 20 V VR rating covers USB PD 3.0 20 V profiles; 1.6 ns trr prevents cross-conduction during hot-plug transitions. |
| Point-of-Load DC-DC Converter | IoT Sensor Node Power Management |
Use Scenario: Output rectification in 12 V → 3.3 V synchronous buck converter for FPGA or SoC core rails. IC Role / Device Role / Timing Role: Freewheeling diode complementing high-side MOSFET; conducts during low-side switch off-time. Use Value: Sub-500 mV VF maintains >94% efficiency at 1 A load, reducing thermal load on 2-layer PCBs without heatsinks. |
Use Scenario: Battery backup path isolation in coin-cell powered environmental sensors with BLE radio. IC Role / Device Role / Timing Role: Ideal diode replacement preventing battery discharge through main 3.3 V regulator when external power is applied. Use Value: 87 µA max IR at 20 V ensures <1 µA standby current drain, extending 220 mAh CR2032 battery life beyond 10 years in sleep mode. |
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), SOD-523 package (1.2 × 0.8 mm), VF = 370 mV @ 100 mA | Lower current rating and higher VF at 1 A makes it unsuitable for 1 A continuous loads; better for signal-level clamping | Select only if VR margin >10 V required and average current <200 mA |
| NSR20F20NXT5G | 20 V VR, 2 A IF(AV), SOD-123FL package (2.9 × 1.5 mm), VF = 450 mV @ 2 A, Rth(j-a) = 150 K/W | Larger footprint and 2× height (0.9 mm) limit use in ultra-thin designs; higher thermal resistance requires larger copper area | Choose when 2 A derated current or enhanced surge handling (IFSM = 30 A) is needed over size constraints |
Compared with RB521S-30T2R and NSR20F20NXT5G, PMEG2010BELD uniquely balances 1 A capability, sub-0.5 mm height, and 25 K/W junction-to-solder-point thermal resistance - making it optimal for space-limited, thermally constrained 1 A DC-DC outputs where board real estate and profile are primary constraints.

FAQ
Is PMEG2010BELD suitable for automotive applications?
No. Per Nexperia's revision history (v.3, Nov 2022), this part is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select the -Q qualified variant (e.g., PMEG2010BELD-Q) or consult Nexperia's automotive portfolio.
What is the maximum allowable solder point temperature during reflow?
The absolute maximum solder point temperature is not specified, but the datasheet mandates reflow-only assembly with Tsp ≤ 130 °C for 1 A continuous operation. Peak reflow temperature must comply with J-STD-020 Class 1 (≤260 °C for ≤10 s), and post-reflow solder joint integrity is validated only under these conditions.
Can PMEG2010BELD replace a standard PN junction diode in a 5 V supply rail?
Yes - provided VR ≥ 5 V and IF(AV) ≤ 1 A. Its 20 V VR and 1 A rating exceed typical 5 V rail requirements, and its 428 mV VF reduces conduction loss by ~55% versus a 1N4007 (VF ≈ 950 mV @ 1 A), directly improving system efficiency and thermal performance.
Does the cathode marking bar indicate polarity during PCB layout?
Yes. The marking bar on the top surface aligns with Pin 1 (cathode), as confirmed in Table 2 (Pinning information) and Figure 17 (package outline). Correct orientation ensures forward conduction from anode (Pin 2) to cathode (Pin 1); reversed placement causes open-circuit behavior in rectification paths.
