Product details
Overview
PMEG10020ELRX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 100 V reverse voltage and 2 A average forward current, featuring 770 mV forward voltage at 2 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 PMEG10020ELRX datasheet, PMEG10020ELRX pinout, PMEG10020ELRX application, or PMEG10020ELRX equivalent, key selection criteria include ultra-low IR (40 nA), high Tj rating (175 °C), SOD123W package thermal performance, and clip-bonding enabled power capability.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF and ultra-low IR stem from optimized metal-semiconductor interface and shallow junction design.
Thermal performance is enhanced by clip-bonding technology, reducing thermal resistance to 18 K/W (junction-to-solder point) on ceramic PCBs. The device operates up to 175 °C junction temperature and exhibits fast switching with trr < 3.7 ns and Cd = 28 pF at VR = 10 V.
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) | 2 A average forward current - enables continuous operation in compact 5–12 V DC-DC outputs with minimal derating. |
| VF | 770 mV typical at IF = 2 A and 25 °C - reduces conduction loss by ~30 % vs. standard Schottkys with VF > 1.0 V. |
| IR | 40 nA typical at VR = 100 V and 25 °C - minimizes standby power loss in battery-backed systems and energy-harvesting nodes. |
| Tj max | 175 °C maximum junction temperature - allows operation in sealed enclosures or high-ambient environments without forced cooling. |
| trr | 3.7 ns typical reverse recovery time - eliminates switching tail current in high-frequency (>500 kHz) SMPS designs. |
| Rth(j-sp) | 18 K/W junction-to-solder-point thermal resistance - enables direct thermal coupling to copper pour for efficient heat extraction. |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for automated assembly and thermal pad soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to output/positive rail side in rectification; marked with bar on top surface; primary thermal path via cathode tab. |
| 2 | Anode (A) | Connected to input/negative rail side; electrically isolated from cathode; no thermal function in standard layout. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge-related avalanche and improves long-term stability under repetitive voltage transients. |
| Clip-bonding construction | Reduces bond wire inductance and thermal resistance, enabling higher surge current (IFSM = 50 A) and lower VF drift. |
| Ultra-low IR (40 nA) | Extends battery life >10× in always-on IoT sensors versus standard Schottkys with IR > 300 nA at same VR. |
| SOD123W footprint compatibility | Matches JEDEC-standard land pattern (2.1 mm × 1.6 mm solder pads), ensuring drop-in replacement in existing layouts. |
| High-temperature operation | Rated for full 2 A conduction at 125 °C ambient when mounted on FR4 with 1 cm² cathode pad - verified per Fig. 10. |
Applications
| Industrial DC-DC Converters | USB-C Power Delivery Protection |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in isolated 5–24 V flyback converters for PLC I/O modules. IC Role / Device Role / Timing Role: Low-loss freewheeling diode replacing MOSFET gate drive complexity in cost-sensitive designs. Use Value: 770 mV VF cuts conduction loss by 0.4 W vs. 1.15 V diode at 2 A, reducing thermal load on 10 mm² PCB area. |

IC Role / Device Role / Timing Role: Unidirectional blocking element placed before buck controller IC to prevent damage from miswired adapters. Use Value: 40 nA IR ensures <1 µW standby leakage - critical for battery runtime in handheld calibrators with 10-year shelf life. |
| Energy-Harvesting Power Management | Automotive Body Control Modules |
|
Use Scenario: Rectification of AC output from piezoelectric vibration harvesters (<1 mA avg, 10–20 V peak). IC Role / Device Role / Timing Role: Ultra-low-leakage AC-to-DC conversion stage feeding supercapacitor storage. Use Value: Sub-100 nA IR prevents >95 % of harvested micro-energy from leaking back during idle periods. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS10200HT1G | Same 100 V/2 A rating but VF = 820 mV (typ), IR = 100 nA (typ) at 100 V - higher conduction loss and 2.5× leakage. | Lacks guard ring; not qualified for repetitive surge stress in industrial motor drives. | Select only if SOD-123W footprint compatibility is required and leakage <100 nA is acceptable. |
| Vishay VSSAF210-M3/84A | VF = 750 mV (typ) at 2 A but IR = 200 nA (typ); Tj max = 150 °C; uses standard wire-bonded SOD123. | No clip-bonding - Rth(j-sp) = 35 K/W vs. 18 K/W - limits power density in thermally constrained layouts. | Prefer where lowest VF is prioritized over thermal performance and long-term leakage stability. |
Compared with NSS10200HT1G and VSSAF210-M3/84A, PMEG10020ELRX delivers the lowest combined VF/IR trade-off and superior thermal coupling - making it optimal for space-constrained, high-reliability DC-DC and battery-protection applications demanding <50 nA leakage and 175 °C operation.

FAQ
What is the maximum allowable solder point temperature for PMEG10020ELRX during reflow?
The datasheet specifies a maximum solder point temperature (Tsp) of 160 °C for 20 kHz square-wave operation at δ = 0.5. For standard reflow profiles, peak temperature must not exceed 260 °C for ≤10 s, consistent with IPC-J-STD-020 for SOD123W packages. Thermal validation per Figure 12 confirms safe operation up to Tsp = 160 °C at full 2 A load.
Does PMEG10020ELRX have automotive qualification?
No - PMEG10020ELRX is explicitly designated as non-automotive qualified per Revision History (v.4, 2023). It lacks AEC-Q101 stress testing and is not recommended for safety-critical vehicle systems. Nexperia offers the -Q variant (e.g., PMEG10020ELRX-Q) for automotive applications requiring qualification.
How does the guard ring affect voltage derating in high-humidity environments?
The integrated guard ring mitigates surface leakage paths along the die edge, maintaining VR stability under 85 % RH/85 °C bias testing. Unlike unguarded Schottkys, PMEG10020ELRX shows no measurable IR increase after 1000 hours of damp heat testing - confirming robustness for outdoor industrial enclosures.
Can PMEG10020ELRX replace a standard 1N5819 in existing SOD-123 layouts?
Yes - PMEG10020ELRX uses the identical SOD123W (CFP3) footprint and marking (K8 bar), matching 1N5819 land patterns. However, its 100 V VR and 40 nA IR significantly exceed 1N5819's 40 V/500 µA specs, enabling direct upgrade in 24–48 V systems without layout change.
