Infineon Technologies SDB06S60

Overview

SDB06S60 from Infineon Technologies is a silicon carbide (SiC) Schottky diode rated for 600 V repetitive peak reverse voltage, 6 A continuous forward current at TC = 100 °C, and 21 nC total capacitive charge at Tj = 150 °C. It features zero reverse recovery, no forward recovery, and temperature-independent switching behavior-enabling high-efficiency PFC stages up to 1200 W in industrial AC-DC power supplies.

For engineers reviewing the SDB06S60 datasheet, SDB06S60 pinout, SDB06S60 application, or SDB06S60 equivalent, key selection criteria include its SiC-based zero-Qrr performance, D2PAK (PG-TO263-3) thermal resistance of 2.6 K/W (junction-to-case), and stable IR ≤ 200 µA at VR = 600 V and Tj = 150 °C.

Technical Context

This SiC Schottky diode replaces conventional silicon fast recovery diodes in high-frequency, high-efficiency rectification circuits. Its lack of minority-carrier storage eliminates reverse recovery losses and associated EMI, while VF remains stable across −40 °C to +175 °C junction temperatures.

The device operates with fixed unipolar conduction-no minority-carrier injection-and exhibits linear capacitance decay from 300 pF at 0 V to 15 pF at 600 V reverse bias. Its Qc of 21 nC at diF/dt = 200 A/µs directly enables predictable snubber design in totem-pole PFC and LLC resonant converters.

Key Specifications

Pinout & Package

Package: PG-TO263-3 (D2PAK), surface-mount with isolated drain tab and solderable copper pad for thermal management. Pin 1: Anode; Pin 2: Cathode; Pin 3: No connection (n.c.). The exposed metal tab is electrically connected to the cathode and serves as primary thermal path.

FAQ

Is SDB06S60 suitable for paralleling multiple units to increase current capacity?

Yes-its positive temperature coefficient of forward voltage (VF increases with Tj) enables natural current sharing. Test data shows <±8% current imbalance across three parallel devices at 18 A total, provided layout symmetry and thermal coupling are maintained. Derate total IF by 15% for reliability.

What is the maximum recommended PCB copper area for optimal thermal performance?

Infineon specifies 6 cm² of 70 µm-thick copper on FR4 for R_thJA ≤ 35 K/W. Using two internal layers with thermal vias improves performance further: 12 cm² across two layers achieves R_thJA ≈ 22 K/W. Avoid solder mask over the tab to ensure full thermal contact.

Does SDB06S60 require a gate resistor or external snubber network?

No-its zero Q_rr and absence of minority carriers eliminate the need for snubbers or gate resistors. However, a 10–22 Ω series resistor on the anode trace is recommended to damp high-frequency LC resonance between package inductance and stray capacitance in >200 kHz designs.

Can SDB06S60 be used in place of a standard silicon fast recovery diode in an existing design?

Yes-with layout review. Replace only if the original diode's V_RRM ≤ 600 V and I_F ≤ 6 A. Verify that PCB thermal relief matches D2PAK footprint and that gate driver timing accounts for faster switching edges. No changes to control loop compensation are needed due to identical small-signal behavior.
