Product details
Overview
PMEG2005EB from Nexperia is a planar Schottky barrier diode in SOD523 (SC-79) package, rated for 20 V reverse voltage and 500 mA forward current, with typical forward voltage of 430–480 mV at 500 mA. It delivers ultra-low VF for efficiency-critical low-power rectification and clamping in space-constrained portable electronics.
For engineers reviewing the PMEG2005EB datasheet, PMEG2005EB pinout, PMEG2005EB application, or PMEG2005EB equivalent, key selection criteria include its AEC-Q101 qualification, 24–30 pF junction capacitance at 1 V, 400 K/W thermal resistance on FR4, guard ring protection, and cathode-marked SOD523 footprint compatibility.
Technical Context
This Schottky diode uses a planar silicon structure with guard ring edge termination to suppress leakage and improve ruggedness under transient stress. Its low VF stems from optimized metal–semiconductor interface design, enabling high conduction efficiency without PN-junction recovery delay.
Rated for 125 °C junction temperature and qualified per AEC-Q101, it supports automotive-grade reliability in harsh ambient conditions. The SOD523 package's 1.2 mm × 0.8 mm footprint and 0.6 mm height enable integration into ultra-thin handheld devices and wearables where board area and profile are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum DC blocking capability; defines safe operating range in clamping and reverse-polarity protection circuits. |
| Forward Current (IF) | 500 mA continuous - Sustained conduction rating; supports low-current power rail rectification in battery-powered systems. |
| Forward Voltage (VF) | 430–480 mV @ 500 mA - Enables >90% conduction efficiency at nominal load; reduces I²R losses in compact DC/DC paths. |
| Reverse Current (IR) | 7–30 µA @ 10 V - Low leakage preserves battery life in always-on standby circuits and signal-level protection networks. |
| Junction Capacitance (Cd) | 24–30 pF @ 1 V - Supports >100 MHz switching in RF detector and high-speed clamp applications without excessive capacitive loading. |
| Thermal Resistance (Rth(j-a)) | 400 K/W - Limits junction-to-ambient temperature rise to ~200 K at full 500 mA load on standard FR4; requires minimal copper area. |
Pinout & Package
Encapsulated in SOD523 (SC-79) plastic surface-mount package: 1.2 mm × 0.8 mm × 0.6 mm body, single-sided tin-plated FR4 footprint, marking bar indicates cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked side of package; connects to lower potential node in forward-biased operation. |
| 2 | Anode (A) | Positive terminal; unmarked side; ties to higher potential source during conduction; carries full forward current path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling, humidity, and mechanical stress-enables use in infotainment power rails and ADAS sensor interfaces. |

| Ultra-small SOD523 footprint | 1.2 mm × 0.8 mm area saves >60% board space vs. SOD323; compatible with fine-pitch reflow profiles and automated optical inspection. |
| Low VF across current range | VF = 120–480 mV from 0.1 mA to 500 mA-maintains high efficiency across sleep-to-active transitions in IoT endpoint power management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G (ON Semiconductor) | 30 V VR, 200 mA IF, VF = 370 mV @ 100 mA, SOD-523 package, no AEC-Q101 rating | Higher voltage margin but lower current rating; suitable for non-automotive 3.3 V logic clamping only | Select when VR > 20 V is required and AEC-Q101 is not mandated; verify thermal derating at 500 mA. |
| NSR0230HT1G (onsemi) | 30 V VR, 300 mA IF, VF = 450 mV @ 300 mA, SOD-523, AEC-Q101 qualified | Lower IF rating limits use in 500 mA rectification; identical thermal and package behavior below 300 mA | Choose for AEC-Q101 compliance where peak current stays ≤300 mA; confirm layout clearance for same footprint. |
Compared with RB520S-30T1G and NSR0230HT1G, PMEG2005EB uniquely balances 500 mA current handling, 20 V rating, AEC-Q101 qualification, and sub-480 mV VF in SOD523-making it optimal for automotive and portable designs demanding full-rated conduction with minimal thermal overhead.

FAQ
What is the maximum allowable junction temperature for PMEG2005EB?
The absolute maximum junction temperature (Tj) is 125 °C per IEC60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating is required above 85 °C ambient; thermal design must ensure Rth(j-a) × Pdiss < (125 − Tamb).
Is PMEG2005EB suitable for reverse-polarity protection in 5 V systems?
Yes-its 20 V reverse voltage rating provides 4× safety margin over 5 V rails. With 7–30 µA leakage at 10 V and 430–480 mV forward drop, it delivers low-loss, fail-safe protection without compromising efficiency or standby current.
Does the SOD523 package support standard reflow soldering profiles?
Yes-the device is qualified for JEDEC J-STD-020D-compliant lead-free reflow. Recommended peak temperature is 260 °C for ≤30 seconds; Figure 5 in the datasheet specifies exact solder land dimensions and paste volume for reliable attachment.
How does the guard ring affect long-term reliability in humid environments?
The guard ring physically isolates the active Schottky junction from package edges, reducing surface leakage paths. This structure is validated per AEC-Q101 THB (Temperature Humidity Bias) testing, ensuring <1000 h operation at 85 °C/85% RH without parameter drift.
