Nexperia USA Inc. PMEG6045ETPX

Overview

PMEG6045ETPX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 60 V reverse voltage and 4.5 A average forward current, featuring low 460–530 mV forward voltage at 4.5 A and high-temperature operation up to 175 °C junction temperature - deployed in switch-mode power supplies for efficient low-voltage DC-to-DC conversion.

For engineers reviewing the PMEG6045ETPX datasheet, PMEG6045ETPX pinout, PMEG6045ETPX application, or PMEG6045ETPX equivalent, key selection criteria include thermal resistance (12 K/W junction-to-solder-point), reverse leakage (115–400 µA at 60 V/25 °C), clip-bonded SOD128 package power capability, and reflow/wave solder compatibility.

Technical Context

This Schottky diode uses planar construction with an integrated guard ring to enhance ruggedness against electrical overstress and thermal cycling. Its clip-bonding technology enables higher power handling than wire-bonded equivalents in the same SOD128 footprint.

The device exhibits ultrafast reverse recovery (trr ≤ 20 ns) and low diode capacitance (575 pF at 1 V, 200 pF at 10 V), enabling high-frequency switching in DC/DC converters. Reverse leakage rises significantly with temperature - 70–300 mA at 60 V and 125 °C - requiring thermal-aware layout.

FAQ

What is the maximum allowable solder point temperature for PMEG6045ETPX during reflow?

The device is qualified for standard lead-free reflow profiles per JEDEC J-STD-020D, with peak solder point temperature up to 260 °C for ≤30 seconds. The cathode solder point must remain below 260 °C to avoid delamination; thermal profiling should target 245–255 °C peak at the cathode pad per Figure 19 footprint guidelines.

Can PMEG6045ETPX replace a standard 1N5822 in existing designs?

Yes - PMEG6045ETPX offers identical 60 V VR and higher 4.5 A IF(AV) vs. 1N5822's 3 A, with lower VF (460–530 mV vs. ~550 mV) and superior thermal performance. However, its SOD128 footprint differs from DO-201AD; PCB redesign is required unless using an adapter layout.

How does the guard ring affect surge performance?

The integrated guard ring reduces electric field crowding at the silicon edge, raising the device's ability to withstand repetitive 60 V transients at 175 °C without degradation. It improves IFSM survivability to 70 A (8.3 ms half-sine) and suppresses premature avalanche onset during load-dump events in automotive auxiliary supplies.

Is PMEG6045ETPX suitable for reverse battery protection in 24 V systems?

Yes - with 60 V VR and low 460 mV VF, it blocks reverse battery connections up to –24 V while adding <50 mV dropout in forward operation. Its 175 °C rating ensures reliability in hot chassis environments, and the cathode-tab thermal path prevents localized overheating during sustained 4 A fault currents.
