Product details
Overview
PMEG100T20ELRX from Nexperia is a trench-structured Schottky barrier rectifier optimized for high-efficiency power conversion, serving as a freewheeling or OR-ing diode in DC/DC converters and LED drivers. It delivers 2 A average forward current at 156 °C solder point temperature, supports 100 V reverse voltage, exhibits 705–800 mV forward voltage at 2 A and 25 °C, and maintains ultra-low reverse leakage (0.15–1.25 µA at 100 V/25 °C).
For engineers reviewing the PMEG100T20ELRX datasheet, PMEG100T20ELRX pinout, PMEG100T20ELRX application, or PMEG100T20ELRX equivalent, key selection criteria include low Qrr (8.5 nC), clip-bonded thermal performance (Rth(j-sp) = 130 K/W), SOD123W package compatibility, and junction temperature derating behavior up to 175 °C.
Technical Context
This MEGA Schottky rectifier uses trench MOS-based anode geometry to reduce forward voltage while suppressing reverse leakage across temperature. Its low Qrr and fast trr (6 ns step recovery) minimize switching losses in high-frequency SMPS topologies.
The CFP3 (SOD123W) package integrates a copper clip-bonded cathode tab for enhanced thermal conduction-enabling 1.15 W total power dissipation on 1 cm² cathode pad-and features a standardized footprint compatible with automated reflow assembly per IPC-7351.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - Withstands full bus voltage in 48 V industrial DC systems with margin; derates to ~70 V at Tj = 150 °C. |
| Average Forward Current (IF(AV)) | 2 A - Sustained conduction capability under 20 kHz square-wave excitation with δ = 0.5 and Tsp ≤ 156 °C. |
| Forward Voltage (VF) | 705–800 mV @ 2 A, 25 °C - Reduces conduction loss by ≥15% vs. standard Schottkys; drops to 550–620 mV at 150 °C. |
| Reverse Leakage (IR) | 0.15–1.25 µA @ 100 V, 25 °C - Enables >10⁶ Ω isolation in reverse-biased protection circuits at room temperature. |
| Reverse Recovery Charge (Qrr) | 8.5 nC - Low stored charge minimizes EMI and body-diode loss in synchronous rectification and OR-ing applications. |
| Junction-to-Solder-Point Rth | 130 K/W - Enables efficient heat transfer to PCB copper, supporting 2 A continuous operation with minimal thermal rise. |
| Package | SOD123W (CFP3) - 2.6 × 1.7 × 1.0 mm surface-mount outline with flat leads; compatible with standard reflow profiles. |
Pinout & Package
The PMEG100T20ELRX is housed in a 2-terminal CFP3 (SOD123W) plastic SMD package with a clip-bonded cathode tab for improved thermal and electrical performance. The cathode is marked by a bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current exit path; connected to large copper pour for thermal management and low-inductance return routing. |
| 2 | Anode (A) | Current entry node; routed with controlled impedance to minimize ringing during fast switching transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables simultaneous optimization of VF and IR-unachievable with planar Schottky-yielding 705 mV/2 A and <1.25 µA/100 V. |
| Clip-bonded cathode | Reduces thermal resistance to 130 K/W (junction-to-solder-point), enabling 2 A operation without heatsink on FR4 with 1 cm² pad. |
| Low Qrr (8.5 nC) | Minimizes reverse recovery energy loss in high-frequency (>100 kHz) buck converters and active OR-ing controllers. |
| SOD123W footprint | Matches industry-standard layout for drop-in replacement in space-constrained designs; supports IPC-compliant reflow and wave soldering. |
| 175 °C max junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., LED streetlights, industrial PSUs) without derating. |
Applications
| High-Efficiency DC/DC Conversion | LED Lighting Power Supply |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 48 V input buck-boost LED drivers operating at 200 kHz. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode to eliminate reverse recovery loss and reduce thermal stress. Use Value: Achieves >95% efficiency at 2 A load with 0.7 V VF and 8.5 nC Qrr-reducing diode conduction loss by 320 mW vs. legacy Schottky alternatives. | Use Scenario: Reverse polarity protection and OR-ing in multi-string constant-current LED modules powered from redundant 24 V supplies. IC Role / Device Role / Timing Role: Unidirectional current gate ensuring supply redundancy without backfeed; operates in steady-state conduction with minimal voltage drop. Use Value: 0.15 µA leakage at 25 °C prevents standby current drain; 100 V VR rating accommodates transient surges up to ±60 V without breakdown. |
| Switch Mode Power Supply Output | Freewheeling in Automotive DC/DC |
Use Scenario: Output rectification in non-isolated 12 V → 3.3 V buck converter for FPGA core power in telecom infrastructure. IC Role / Device Role / Timing Role: Main output rectifier handling continuous 2 A DC load with pulsed current peaks up to 50 A (IFSM). Use Value: 2.8 A absolute max forward current (δ = 1) and 50 A IFSM support transient overloads without thermal runaway or bond-wire failure. | Use Scenario: Freewheeling path in 12 V automotive DC/DC converters driving infotainment displays, exposed to ambient temperatures up to 105 °C. IC Role / Device Role / Timing Role: Inductor current recirculation path during MOSFET off-time; must operate reliably at Tj = 150 °C with stable VF. Use Value: VF drops to 590–660 mV at 125 °C-maintaining low conduction loss-and IR remains <1.2 mA, preventing thermal runaway under sustained reverse bias. |
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-2EY10-M3/54 | Higher VF (820 mV typ @ 2 A), larger SOD-123 package (no clip bonding), Rth(j-a) = 250 K/W. | Limited to lower-power or lower-frequency applications due to higher thermal resistance and conduction loss. | Select when cost sensitivity outweighs efficiency targets and thermal constraints are relaxed. |
| ON Semiconductor NSR20F100XT1G | Lower VR (100 V same), but higher IR (1.5 µA @ 100 V/25 °C), no Qrr spec published, Rth(j-sp) not characterized. | Not recommended for high-reliability OR-ing where low leakage and predictable recovery are critical. | Choose only for non-critical 24 V systems where leakage <2 µA is acceptable and thermal margin is abundant. |
Compared with VS-2EY10-M3/54 and NSR20F100XT1G, PMEG100T20ELRX provides superior thermal performance (130 K/W vs. ≥250 K/W), lower leakage (0.15 µA vs. ≥1.5 µA), and quantified Qrr-making it the preferred choice for compact, high-efficiency, thermally constrained DC/DC and LED driver designs.

FAQ
What is the maximum allowable solder point temperature for continuous operation?
The PMEG100T20ELRX supports continuous operation with a maximum solder point temperature (Tsp) of 156 °C under δ = 0.5 square-wave conditions at 20 kHz. At DC (δ = 1), the limit drops to 150 °C. Exceeding these values risks accelerated degradation of the clip bond and increased forward voltage drift.
Does this diode require a heatsink in typical 2 A applications?
No heatsink is required when mounted on an FR4 PCB with a 1 cm² tin-plated copper pad on the cathode side, where its Rth(j-sp) of 130 K/W enables safe 2 A operation at ambient temperatures up to 85 °C. Thermal simulation is advised if the copper area is reduced below 0.5 cm² or airflow is restricted.
How does reverse leakage change at elevated junction temperatures?
Reverse leakage increases exponentially with temperature: from 0.15–1.25 µA at 25 °C to 0.28–1.2 mA at 125 °C and 1.1–5.5 mA at 150 °C under 100 V bias. This behavior is fully characterized in Table 7 and must be accounted for in high-temperature reverse-bias protection circuits.
Is the SOD123W footprint compatible with standard reflow soldering processes?
Yes-the CFP3 (SOD123W) package is qualified for lead-free reflow per J-STD-020, with recommended stencil thickness of 0.1 mm and land pattern dimensions matching IPC-7351 Class L. Figure 19 provides the exact reflow footprint, including solder mask and paste definitions for reliable assembly yield.
