Product details
Overview
PMEG100T20ELR-QX from Nexperia is a 100 V, 2 A trench Schottky barrier rectifier in CFP3 (SOD123W) package, designed for high-efficiency DC-DC conversion and automotive LED lighting. It delivers low forward voltage (705–800 mV at 2 A, 25 °C), ultra-low reverse leakage (0.15–1.25 µA at 100 V, 25 °C), and qualified to AEC-Q101 for automotive use.
For engineers reviewing the PMEG100T20ELR-QX datasheet, PMEG100T20ELR-QX pinout, PMEG100T20ELR-QX application, or PMEG100T20ELR-QX equivalent, key selection criteria include reverse leakage current at 125 °C, thermal resistance to solder point (130 K/W), junction temperature rating (175 °C), and clip-bonded power capability in SOD123W footprint.
Technical Context
This device uses trench Schottky architecture to minimize forward voltage and reverse recovery charge (Qrr = 8.5 nC), enabling high-frequency switching with reduced conduction and switching losses. Its clip-bonding construction enhances thermal performance and current handling beyond standard wire-bonded SOD123W diodes.
The cathode-terminal layout and marking bar align with industry-standard polarity identification for automated placement. Thermal design leverages dual thermal paths: junction-to-ambient (220 K/W on standard FR4) and junction-to-solder-point (130 K/W with 1 cm² cathode pad), supporting robust power dissipation up to 1.15 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - Maximum blocking voltage before breakdown; enables use in 48 V automotive systems with margin. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC or pulsed current capability at Tsp ≤ 156 °C; supports continuous operation in compact PCB layouts. |
| Forward Voltage (VF) | 705–800 mV @ 2 A, 25 °C - Low conduction loss improves efficiency in high-current freewheeling and OR-ing paths. |
| Reverse Leakage (IR) | 0.15–1.25 µA @ 100 V, 25 °C - Enables stable biasing in high-impedance circuits and reduces standby power loss. |
| Junction Temperature (Tj) | 175 °C - High thermal limit allows operation in under-hood automotive environments without derating. |
| Thermal Resistance (Rth(j-sp)) | 130 K/W - Low junction-to-solder-point resistance enables effective heat transfer via cathode pad to PCB copper. |
| Reverse Recovery Charge (Qrr) | 8.5 nC - Minimizes switching loss during turn-off in SMPS and synchronous rectification applications. |
Pinout & Package
Encapsulated in CFP3 (SOD123W) plastic SMD package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for reflow soldering and space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; marked with bar; connects to system ground or return path in reverse polarity protection. |
| 2 | Anode (A) | Input terminal for forward conduction; connects to input rail in freewheeling or OR-ing configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF and Qrr vs. planar Schottky, improving efficiency in 100 kHz–1 MHz DC-DC converters. |

| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A110. |
| Low IR at 125 °C | 0.28–1.2 mA @ 100 V ensures minimal leakage-induced voltage drift in hot under-hood LED drivers. |
| Standard SOD123W footprint | Enables drop-in replacement of legacy Schottkys without PCB redesign; compatible with JEDEC MS-012AC outline. |
Applications
| Automotive LED Lighting | High-Efficiency DC-DC Conversion |
|---|---|

IC Role / Device Role / Timing Role: Back-to-back configured diode enabling automatic source selection without control logic. Use Value: 2 A IF(AV) supports >10 W load sharing; low IR ensures minimal voltage offset between sources, preventing cross-conduction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS2L100S | 100 V, 2 A; VF = 790 mV typ @ 2 A; Rth(j-a) = 240 K/W; not AEC-Q101 qualified. | Limited to industrial/commercial use; lacks automotive stress test validation. | Select when AEC-Q101 compliance is not required and higher thermal resistance is acceptable. |
| RB055LAM-40 | 40 V, 5 A; VF = 450 mV typ @ 5 A; lower VR limits use to ≤24 V systems. | Not suitable for 48 V automotive or 100 V transient-tolerant designs. | Choose only for low-voltage, high-current applications where VR margin is not critical. |
Compared with STPS2L100S and RB055LAM-40, PMEG100T20ELR-QX uniquely combines AEC-Q101 qualification, 100 V VR, and 130 K/W Rth(j-sp) in SOD123W-making it the only option validated for thermally demanding automotive LED and OR-ing roles requiring both voltage margin and low thermal impedance.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C, and the device is rated for continuous average forward current of 2 A at solder point temperature ≤156 °C. Derating curves in Figures 8–10 confirm sustained operation up to 175 °C junction temperature when mounted on FR4 with ≥1 cm² cathode copper area.
How does the clip-bonding technology improve thermal performance over standard wire-bonded SOD123W diodes?
Clip-bonding replaces aluminum bond wires with a copper clip connecting the die directly to the cathode leadframe, reducing thermal resistance by ~30% (Rth(j-sp) = 130 K/W vs. typical 180+ K/W). This enables higher power dissipation (1.15 W) and improved reliability under thermal cycling in automotive under-hood environments.
Is PMEG100T20ELR-QX suitable for reverse polarity protection in 48 V mild-hybrid vehicles?
Yes. With 100 V reverse voltage rating and AEC-Q101 qualification, it withstands ISO 7637-2 load dump pulses (up to 120 V transient) and operates reliably from –40 °C to 175 °C. Its low 0.28–1.2 mA IR at 125 °C prevents excessive power loss during extended hot-soak conditions.
What is the significance of the "LB" marking code on the device body?
The "LB" marking identifies the PMEG100T20ELR-QX variant per Nexperia's ordering matrix. The bar adjacent to pin 1 indicates the cathode terminal, providing unambiguous polarity orientation for automated optical inspection (AOI) and pick-and-place systems during SMT assembly.
