Diodes Incorporated PDS760Q-13

Overview

PDS760Q from Diodes Incorporated is a 60 V, 7 A Schottky barrier rectifier in PowerDI5 package, featuring 0.62 V max forward voltage at 7 A and 0.2 mA max reverse leakage at 60 V and +25°C. It is AEC-Q101 qualified and designed for automotive polarity protection, freewheeling, and high-frequency switching applications.

For engineers reviewing the PDS760Q datasheet, PDS760Q pinout, PDS760Q application, or PDS760Q equivalent, key selection criteria include its low VF (0.41–0.62 V), high IFSM (275 A), thermal resistance (RθJS = 1.5 °C/W), AEC-Q101 qualification, and PowerDI5 thermal pad layout requirements.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient robustness and suppress avalanche-induced failure during inductive load switching. Its low forward voltage drop and minimal reverse recovery charge enable high-efficiency operation in 100 kHz–1 MHz DC/DC converters and motor drive freewheel paths.

Thermal performance is optimized via a bottom-side heat sink interface in the PowerDI5 package, delivering RθJS = 1.5 °C/W when mounted on recommended copper pads. Reverse leakage remains under 20 µA at +125°C and 60 V, supporting stable operation in under-hood automotive environments.

FAQ

What is the maximum junction temperature for continuous operation?

The PDS760Q supports continuous operation from –55°C to +150°C junction temperature. At rated 7 A IO, junction temperature rise is limited to 10.5°C above solder point (ΔT = IO² × RθJS × RθSJ ≈ 7² × 1.5 × 0.1) when mounted per Note 7 layout, enabling full-rated current at +140°C ambient in well-designed assemblies.

Is the PowerDI5 package lead-free and RoHS compliant?

Yes. The PDS760Q-13 features matte tin annealed over copper leadframe and green molding compound meeting RoHS 3 (2015/863/EU), with bromine and chlorine each <900 ppm and antimony <1000 ppm. Full compliance documentation is available via Diodes' Quality Portal.

How should the left and right pins be connected on the PCB?

The left (anode) and right (cathode) pins must be electrically connected to their respective copper traces and also shorted together on the PCB layer beneath the device per the "LEFT PIN RIGHT PIN" note. This ensures mechanical anchoring and current sharing between pins, preventing solder joint fatigue under thermal cycling.

Does this part require derating for capacitive loads?

Yes. For capacitive loads, the average forward current rating must be reduced by 20% per the datasheet - limiting IO to 5.6 A. This accounts for higher peak currents during capacitor charging transients, which increase junction temperature beyond resistive/inductive load assumptions.
