Product details
Overview
PMEG100T30ELRX from Nexperia is a trench Schottky barrier rectifier optimized for high-efficiency power conversion in space-constrained SMD designs. It delivers 3 A average forward current at 100 V reverse voltage, with low 705 mV typical forward voltage at 3 A and ultra-low 0.25 µA reverse leakage at 100 V/25 °C - enabling reduced conduction loss and thermal stress in DC-DC converters and LED drivers.
For engineers reviewing the PMEG100T30ELRX datasheet, PMEG100T30ELRX pinout, PMEG100T30ELRX application, or PMEG100T30ELRX equivalent, key selection criteria include its CFP3 (SOD123W) package thermal performance, trench-based low-Qrr recovery behavior, and cathode-marked 2-pin configuration for reverse polarity protection and OR-ing circuits.
Technical Context
This device uses a trench Schottky architecture to minimize forward voltage while maintaining high reverse blocking capability. Its clip-bonding construction enhances thermal transfer from junction to solder point (Rth(j-sp) = 130 K/W on 1 cm² cathode pad), supporting sustained 3 A operation under δ = 0.5 square-wave conditions up to Tsp ≤ 153 °C.
The diode exhibits step-recovery trr of 9 ns and ramp-recovery trr of 12.5 ns at 25 °C, with Qrr of only 10 nC - critical for minimizing switching losses in high-frequency SMPS and freewheeling paths. Reverse leakage remains below 2.2 mA even at 125 °C and 100 V, ensuring stable performance across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V maximum reverse voltage - enables use in 48 V and 60 V bus systems with safety margin. |
| IF(AV) | 3 A average forward current - supports continuous output in compact 20 kHz SMPS designs. |
| VF @ 3 A | 705 mV typical forward voltage - reduces conduction loss by ~30% vs. planar Schottkys at same rating. |
| IR @ 100 V / 25 °C | 0.25 µA typical reverse leakage - minimizes standby power loss in battery-backed OR-ing applications. |
| Qrr | 10 nC reverse recovery charge - lowers switching node ringing and EMI in high-dV/dt environments. |
| Rth(j-sp) | 130 K/W junction-to-solder-point thermal resistance - allows 1.15 W dissipation with 1 cm² cathode copper area. |
| trr (step) | 9 ns reverse recovery time - enables clean turn-off in synchronous rectifier control schemes. |
Pinout & Package
Encapsulated in the CFP3 (SOD123W) surface-mount plastic package (2.6 mm × 1.7 mm × 1.0 mm), this diode uses a flat lead, dual-terminal layout with cathode-side marking bar for unambiguous orientation during automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to negative rail or return path; marked by bar on package body - defines current flow direction and polarity protection orientation. |
| 2 | Anode (A) | Connected to input/high-side node; carries full load current into cathode - requires adequate copper pour for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Enables lower VF and higher VR trade-off than planar Schottky - critical for 100 V-class efficiency targets. |
| Clip-bonding technology | Reduces thermal resistance by ~40% vs. wire-bonded equivalents - sustains higher IF(AV) in minimal PCB area. |
| Low Qrr (10 nC) | Minimizes energy loss and voltage overshoot during diode turn-off - improves reliability in hard-switched topologies. |
| Ultra-low IR at 125 °C | 2.2 mA max reverse leakage at 100 V/125 °C - maintains system efficiency in thermally demanding LED driver enclosures. |
| SOD123W footprint compatibility | Drop-in replacement for legacy 3 A Schottkys using standard reflow stencil (0.1 mm thickness) and 1.1 mm × 1.1 mm land pattern. |
Applications
| High-Efficiency DC-DC Conversion | LED Lighting Drivers |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48 V–60 V input buck-derived LED drivers operating at 200–500 kHz. IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss current path during high-side switch off-time. Use Value: 705 mV VF at 3 A reduces conduction loss by 0.5 W vs. conventional Schottky, lowering heatsink requirements in sealed luminaires. |
Use Scenario: Reverse polarity protection at input stage of constant-current LED modules powered from 24 V or 48 V supplies. IC Role / Device Role / Timing Role: Unidirectional blocking element preventing damage during connector misinsertion or supply reversal. Use Value: 0.25 µA IR at 25 °C ensures <1 µW standby leakage - preserves battery life in portable LED signage and emergency lighting. |
| Switch Mode Power Supply Output | OR-ing Circuit for Redundant Supplies |
Use Scenario: Output rectification in non-isolated 12 V/3 A buck converters for telecom and industrial control boards. IC Role / Device Role / Timing Role: Main output diode handling continuous 3 A load with minimal voltage drop and thermal rise. Use Value: Rth(j-sp) = 130 K/W enables 1.15 W dissipation with only 1 cm² cathode copper - eliminates need for thermal vias in cost-sensitive designs. |
Use Scenario: Diode-based OR-ing in dual 48 V supply systems for network switches and servers requiring seamless failover. IC Role / Device Role / Timing Role: Forward-biased isolation element allowing active supply to power load while blocking reverse current from backup. Use Value: Low Qrr (10 nC) prevents cross-conduction during supply switchover - avoids momentary short-circuit between rails. |
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-3EYH01-M3/54 | Higher VF (820 mV typ @ 3 A), larger SMC (DO-214AB) package, no trench structure. | Less suitable for high-density layouts; higher conduction loss increases thermal load in enclosed spaces. | Select when board-level thermal mass is high and footprint constraints are relaxed. |
| ON Semiconductor NSR30C100X | Lower VR (100 V max but derated to 85 V at 125 °C), similar VF (710 mV), same CFP3 package. | Not recommended for 100 V bus applications at elevated ambient temperatures due to tighter VR derating. | Select only for 48 V systems where full 100 V margin is unnecessary and cost is primary driver. |
Compared with VS-3EYH01-M3/54 and NSR30C100X, PMEG100T30ELRX uniquely combines trench-enabled low VF, industry-leading low IR at high temperature, and CFP3 thermal performance - making it optimal for compact, high-efficiency, and thermally constrained 100 V-class rectification.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C per IEC 60134 limiting values. For reliable long-term operation, junction temperature should be maintained ≤150 °C under worst-case ambient and power dissipation conditions - achievable with ≥1 cm² cathode copper area and proper airflow.
Does PMEG100T30ELRX support wave soldering?
Yes - Nexperia provides dedicated wave soldering footprint data (Fig. 20) for the CFP3 package: 2.55 mm × 3.0 mm solder lands with 3.15 mm spacing, 2.4 mm dummy tracks, and 8.3 mm total length. Preheat and peak temperature profiles must comply with IPC-J-STD-020.
How does its reverse recovery compare to standard Schottky diodes?
Unlike conventional Schottkys that exhibit soft recovery, PMEG100T30ELRX shows step-recovery behavior with trr = 9 ns and Qrr = 10 nC - resulting from its trench structure. This yields sharper turn-off, lower switching loss, and reduced EMI versus planar devices with similar ratings.
Is the marking code 'LC' sufficient for full traceability?
Yes - 'LC' is the official Nexperia marking for PMEG100T30ELRX per Table 4. Combined with date code and reel label, it enables full lot traceability back to wafer fabrication and assembly. No secondary markings or suffixes are used for this variant.
