Product details
Overview
PMEG3005EL/S500315 from Nexperia is a 30 V, 500 mA low-leakage Schottky barrier diode in SOD-123W package, featuring 0.45 V forward voltage at 500 mA and 1.5 µA reverse current at 30 V, used in power rail clamping and USB port protection circuits.
For engineers reviewing the PMEG3005EL/S500315 datasheet, PMEG3005EL/S500315 pinout, PMEG3005EL/S500315 application, or PMEG3005EL/S500315 equivalent, key selection criteria include low VF for efficiency, ultra-low IR for standby power integrity, SOD-123W thermal performance, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode employs a planar silicon epitaxial construction with metal–semiconductor junction optimized for low forward voltage and minimal reverse leakage. Its junction capacitance of 35 pF at 1 V supports fast transient response in ESD clamp networks.
The device operates across –65 °C to +150 °C ambient range and meets IEC 61000-4-2 Level 4 (±8 kV contact discharge) when integrated into compliant PCB layouts, enabling robust system-level ESD immunity without external TVS devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G | Higher VF (0.52 V), higher IR (3 µA), same SOD-123 package without thermal pad | Limited to non-automotive consumer ports due to lack of AEC-Q101 and lower ESD rating | Choose RB520S-40T1G only for cost-sensitive, non-automotive designs where thermal margin is ≥25 °C above ambient |
| SS34-HF | Higher current rating (3 A), larger DO-214AC package, VF = 0.5 V, IR = 500 µA | Suitable for high-power 12 V/24 V systems but incompatible with space-constrained USB or sensor PCBs | Select SS34-HF when board layout permits larger footprint and system requires >1 A surge handling capability |
Compared with RB520S-40T1G and SS34-HF, PMEG3005EL/S500315 uniquely balances ultra-low leakage, automotive qualification, and compact thermal-enhanced packaging-making it optimal for space- and reliability-critical 5 V/12 V interface protection where standby power and ESD immunity are co-constrained.

FAQ
What is the maximum continuous forward current rating for PMEG3005EL/S500315?
The PMEG3005EL/S500315 is rated for 500 mA continuous forward current at Ta = 25 °C with derating to 350 mA at 100 °C ambient. This rating assumes PCB layout with 25 mm² copper pour on both sides connected to the SOD-123W thermal pad, per Nexperia Application Note AN10273.
Is PMEG3005EL/S500315 qualified for automotive applications?
Yes, PMEG3005EL/S500315 is fully AEC-Q101 qualified and tested for temperature cycling, high-temperature reverse bias, and humidity testing per automotive reliability standards. It is approved for use in body electronics, infotainment, and ADAS power interfaces.
What is the reverse recovery time of PMEG3005EL/S500315?
The PMEG3005EL/S500315 is a Schottky diode and has no minority-carrier reverse recovery time. Its switching behavior is governed by junction capacitance (35 pF) and series resistance, enabling nanosecond-scale turn-off essential for ESD clamp speed.
Can PMEG3005EL/S500315 replace standard PN-junction diodes in 5 V rail clamping?
Yes, PMEG3005EL/S500315 can directly replace PN diodes like 1N4148 in 5 V clamping roles, delivering 0.45 V forward drop versus ~0.7 V and eliminating reverse recovery tail current-reducing noise coupling and improving transient response in PMEG3005EL/S500315-based designs.
Does PMEG3005EL/S500315 require a heatsink for 500 mA operation?
No, PMEG3005EL/S500315 does not require an external heatsink at 500 mA when mounted on a standard FR-4 PCB with 25 mm² copper area connected to its SOD-123W thermal pad. Its Rth(j-a) of 290 K/W ensures junction temperature remains below 125 °C at 40 °C ambient.
