Product details
Overview
PMEG3005AEV,115 from Nexperia is a 30 V, 500 mA low-leakage Schottky barrier diode in SOD-123W package, optimized for high-efficiency power management in space-constrained portable electronics and USB power switches.
For engineers reviewing the PMEG3005AEV,115 datasheet, PMEG3005AEV,115 pinout, PMEG3005AEV,115 application, or PMEG3005AEV,115 equivalent, key selection criteria include forward voltage at 500 mA, reverse leakage at 30 V, thermal resistance, junction-to-ambient capability, and SOD-123W footprint compatibility with automated assembly.
Technical Context
This Schottky diode employs a planar silicon epitaxial construction to achieve low forward voltage drop and minimal reverse recovery charge. Its low leakage current (≤2 µA at 30 V, Tj = 125 °C) supports battery-sensitive applications where standby power loss must be minimized.
The SOD-123W package features enhanced thermal performance over standard SOD-123, with Rth(j-a) = 270 K/W and Rth(j-l) = 80 K/W, enabling reliable operation at continuous 500 mA under typical PCB layout conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-30T2R | Higher IR (10 µA @ 30 V, 125 °C); same SOD-523 package; lower IF rating (200 mA) | Not suitable for 500 mA continuous loads; limited to low-current bias rails | Select RB521S-30T2R only when board space is critical and current demand ≤200 mA |
| SS32HE3_A/H | Higher VF (550 mV @ 500 mA); SMA package; higher thermal resistance (Rth(j-a) = 350 K/W) | Requires larger PCB copper area; less efficient in thermally constrained designs | Choose SS32HE3_A/H only if existing SMA footprint reuse is mandatory and efficiency loss is acceptable |
Compared with RB521S-30T2R and SS32HE3_A/H, PMEG3005AEV,115 uniquely balances 500 mA current handling, ultra-low leakage, and SOD-123W thermal performance-making it optimal for compact, battery-sensitive, and automotive-grade power paths where both efficiency and reliability are non-negotiable.

FAQ
What is the maximum continuous forward current rating for PMEG3005AEV,115?
The PMEG3005AEV,115 is rated for 500 mA continuous forward current under standard PCB mounting conditions (FR4, 1 cm² copper pad). This rating assumes ambient temperature ≤60 °C and accounts for its SOD-123W package thermal resistance of 270 K/W. Derating is required above 60 °C ambient.
Does PMEG3005AEV,115 meet automotive qualification standards?
Yes, PMEG3005AEV,115 is AEC-Q101 qualified for automotive applications. It has passed stress tests including high-temperature operating life, temperature cycling, and humidity bias HAST, supporting use in body control modules and infotainment power supplies where ambient temperatures reach 125 °C.
What is the reverse leakage current of PMEG3005AEV,115 at 30 V and 125 °C?
The reverse leakage current of PMEG3005AEV,115 is guaranteed ≤2 µA at VR = 30 V and Tj = 125 °C. This ultra-low leakage is critical for battery-powered systems where standby current directly impacts shelf life and operational runtime.
Can PMEG3005AEV,115 replace standard SOD-123 Schottky diodes in existing layouts?
Yes, PMEG3005AEV,115 uses the SOD-123W package, which shares identical outline dimensions (2.7 × 1.7 mm) with standard SOD-123 but adds an exposed cathode pad. It is mechanically compatible with SOD-123 footprints, though optimal thermal performance requires connection of the cathode pad to a thermal copper area.
What is the typical forward voltage of PMEG3005AEV,115 at 100 mA?
The typical forward voltage of PMEG3005AEV,115 is 360 mV at IF = 100 mA and Tj = 25 °C. At higher currents (e.g., 500 mA), VF rises to 450 mV max, enabling low-loss operation across common portable power rail currents.
