Product details
Overview
PMEG10010ELRX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 100 V reverse voltage and 1 A average forward current, featuring 710 mV forward voltage at 1 A and only 40 nA reverse leakage at 100 V and 25 °C - deployed in low-power DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG10010ELRX datasheet, PMEG10010ELRX pinout, PMEG10010ELRX application, or PMEG10010ELRX equivalent, this device is selected for high-efficiency, low-leakage rectification where thermal robustness (Tj ≤ 175 °C) and compact SOD123W packaging are critical in space-constrained power rails.
Technical Context
This Schottky diode uses planar die construction with an integrated guard ring to suppress edge breakdown and improve reliability under voltage transients. Its clip-bonding technology enhances thermal conduction and power handling versus wire-bonded alternatives.
It exhibits ultra-low reverse leakage (40 nA typical at VR = 100 V, Tj = 25 °C), enabling use in battery-sensitive systems, and delivers fast switching with trr < 4 ns and negligible minority-carrier storage - eliminating reverse recovery loss in high-frequency SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 100 V maximum reverse voltage - supports input stages in 48 V industrial supplies and PoE-powered devices. |
| IF(AV) | 1 A average forward current - sustains continuous operation in 5–12 V output rails with moderate load currents. |
| VF @ 1 A | 710 mV typical - reduces conduction loss by ~30% vs. standard silicon diodes, improving efficiency in portable battery systems. |
| IR @ 100 V | 40 nA typical at 25 °C - enables microamp-level standby current in always-on circuits and energy-harvesting nodes. |
| Tj max | 175 °C junction temperature - allows operation in sealed enclosures or near heat sources without derating penalties. |
| trr | 3.7 ns typical - eliminates reverse recovery tail, enabling >1 MHz switching in synchronous buck topologies. |
| Cd @ 10 V | 28 pF diode capacitance - minimizes capacitive switching loss and EMI in high-dV/dt applications. |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount package - 2.6 mm × 1.7 mm × 1.0 mm body with flat leads optimized for thermal dissipation on FR4 or ceramic PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked side of package; connects to output/positive rail in reverse polarity protection; carries full forward current and dissipates most power. |
| 2 | Anode (A) | Unmarked terminal; connects to input/negative rail; serves as return path during forward conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge-related avalanche breakdown, increasing voltage surge tolerance in transient-prone inputs. |
| Clip-bonding interconnect | Reduces thermal resistance (Rth(j-sp) = 18 K/W) and improves current-carrying capacity over wire bonding. |
| Low IR at high Tj | 500 µA max reverse current at 125 °C and 100 V - maintains leakage integrity in automotive under-hood environments. |
| SOD123W footprint compatibility | Standardized land pattern per Nexperia's reflow guidelines (1.2 mm × 1.4 mm solder pads) ensures manufacturability across SMT lines. |
Applications
| Reverse Polarity Protection | High-Efficiency DC-DC Converter |
|---|---|
Use Scenario: Input protection for USB-C PD adapters and 24 V industrial controllers exposed to accidental reverse battery connection. IC Role / Device Role / Timing Role: Unidirectional current valve placed in series with input rail; conducts only when anode is more negative than cathode. Use Value: Prevents damage to downstream ICs with zero forward voltage penalty (<710 mV drop), preserving system efficiency and thermal margin. | Use Scenario: Output rectification in 500 kHz buck converter powering FPGA core voltage (1.2 V @ 3 A). IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss current path during high-side switch off-time. Use Value: Enables >94% conversion efficiency at light loads due to sub-1 V VF and <4 ns trr, minimizing switching and conduction losses. |
| Low-Voltage Rectification | Low-Power Consumption System |
Use Scenario: AC-to-DC rectification for 3.3 V auxiliary supply derived from 5 V wall adapter with center-tapped transformer. IC Role / Device Role / Timing Role: Half-wave rectifier converting transformer secondary AC into unidirectional pulsating DC. Use Value: Delivers stable bias with minimal dropout (710 mV) and no reverse recovery noise, simplifying filter design and reducing EMI filtering cost. | Use Scenario: Power path management in wireless sensor node powered by coin cell (CR2032) with 10-year battery life target. IC Role / Device Role / Timing Role: Isolation diode preventing backfeed between dual power sources (battery + energy harvester). Use Value: Limits quiescent current drain to <50 nA, extending operational lifetime by minimizing standby leakage in multi-source architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS110HE3/5AT | Same 100 V VR and 1 A IF(AV), but VF = 850 mV (typ) and IR = 100 nA (max) - higher conduction loss and leakage. | Less suitable for battery-critical systems requiring sub-50 nA leakage at room temperature. | Select when legacy footprint compatibility with SMA package is required and thermal budget permits higher VF. |
| ON Semiconductor SB1100-T1-GE3 | 100 V VR, 1 A IF(AV), VF = 800 mV (typ), IR = 200 nA (max); SOD-123 package (not SOD123W) - lower power capability and thermal performance. | Not recommended for sustained 1 A operation above 85 °C ambient due to higher Rth(j-a) and no clip-bonding. | Choose only for cost-sensitive, non-thermal-critical consumer applications where SOD-123 footprint suffices. |
Compared with SS110HE3/5AT and SB1100-T1-GE3, PMEG10010ELRX offers superior leakage control (40 nA vs. ≥100 nA), lower VF (710 mV vs. ≥800 mV), and enhanced thermal robustness via clip-bonding - making it optimal for high-reliability, thermally constrained, and ultra-low-power designs.

FAQ
What is the maximum allowable solder point temperature for PMEG10010ELRX during reflow?
The device supports peak reflow temperatures up to 260 °C for ≤30 seconds per JEDEC J-STD-020, with recommended solder profile aligned to IPC-7095. The cathode tab's solder point thermal resistance is 18 K/W, confirming robust thermal coupling to PCB copper - critical for maintaining Tj ≤ 175 °C under 1 A DC load.
Does PMEG10010ELRX have automotive qualification?
No - PMEG10010ELRX is not AEC-Q200 qualified. Per Nexperia's revision history (v.5, Jan 2023), this part was explicitly changed to non-automotive qualification. For automotive applications, Nexperia offers the -Q variant (e.g., PMEG10010ELRX-Q), which undergoes extended temperature cycling, humidity testing, and failure analysis per AEC standards.
How does the guard ring affect voltage derating in transient conditions?
The integrated guard ring mitigates electric field crowding at the die edge, allowing the device to withstand repetitive 100 V transients without premature breakdown. In practice, this permits operation at VR = 100 V without additional derating in 24 V or 48 V systems subject to ISO 7637-2 pulse 1/2a, unlike non-guarded Schottky diodes that typically require ≥20% voltage margin.
Can PMEG10010ELRX replace a standard 1N5819 in existing designs?
Yes - with caveats. It shares identical SOD-123W footprint and 1 A/100 V ratings, but its 710 mV VF (vs. 1N5819's ~900 mV) lowers conduction loss, while its 40 nA IR (vs. ~1 µA) drastically cuts leakage. However, layout must verify cathode pad area (1 cm² recommended) to achieve full 1 A rating - unlike 1N5819, which relies on less aggressive thermal design.
