Diodes Incorporated PDS360Q-13

Overview

PDS360Q-13 from Diodes Incorporated is a 60 V, 3 A automotive-grade Schottky barrier rectifier in POWERDI5 package, featuring 0.62 V max forward voltage at 3 A and 0.15 mA max reverse leakage at 60 V and +25°C; designed for polarity protection and freewheeling in 12 V automotive power rails.

For engineers reviewing the PDS360Q-13 datasheet, PDS360Q-13 pinout, PDS360Q-13 application, or PDS360Q-13 equivalent, key selection criteria include AEC-Q101 qualification, low VF at high junction temperature, thermal resistance to solder point (3.0 °C/W), and validated surge capability (100 A IFSM) in compact surface-mount form.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient immunity and suppress avalanche-induced failure during load dump events. Its low barrier height enables stable 0.57 V typical VF at 3 A and +25°C, with VF rising only marginally to 0.51 V at +125°C under same current-critical for thermally constrained engine bay layouts.

Thermal performance is defined by three RθJA values (95/70/50 °C/W) depending on PCB material and pad layout, while RθJS = 3.0 °C/W confirms efficient heat transfer to the solder joint. Reverse leakage remains ≤15 μA at +100°C and VR = 60 V, supporting reliable operation in high-temperature under-hood environments.

Key Specifications

Pinout & Package

POWERDI5 is a dual-terminal, surface-mount plastic package with exposed cathode thermal pad on bottom side; anode and cathode terminals are located on left and right edges respectively, requiring PCB-level connection of both pins to ground plane for optimal thermal and electrical performance.

FAQ

What is the maximum allowable junction temperature for continuous operation?

The PDS360Q-13 is rated for continuous operation up to +150°C junction temperature. Derating curves in Figure 5 confirm 3 A average forward current is maintainable up to +100°C ambient on FR-4 PCB with minimum recommended pad layout; above that, current must be reduced linearly to zero at +150°C ambient.

Does the POWERDI5 package require special soldering profile considerations?

Yes-the exposed cathode thermal pad requires full-surface reflow soldering with stencil-defined paste deposition. Diodes Incorporated recommends a peak reflow temperature of 260°C for 10 seconds, matching JEDEC J-STD-020 Level 1 moisture sensitivity, and specifies minimum pad dimensions (9.4 mm × 7.4 mm cathode, 2.7 mm × 1.6 mm anode) for optimal thermal performance.

How does the guard ring structure improve transient robustness?

The guard ring surrounds the active Schottky junction to control electric field distribution at the silicon edge, preventing premature avalanche breakdown during fast-rising transients like ISO 7637-2 Pulse 5a (load dump). This allows the device to clamp at rated VRRM without destructive failure, unlike non-guarded Schottky diodes which may exhibit parametric drift after repeated surges.

Is the PDS360Q-13 suitable for 24 V commercial vehicle applications?

No-it is rated for 60 V VRRM, providing only 2× margin over nominal 24 V systems, insufficient for ISO 16750-2 load dump (up to 35 V) plus tolerance. For 24 V platforms, Diodes Incorporated recommends PDS560Q (100 V) or PDS660Q (150 V) variants from the same POWERDI5 family to ensure ≥3× safety margin and sustained AEC-Q101 compliance.
