Diodes Incorporated SBG1030CT-T-F

Overview

SBG1030CT-T-F from Diodes Incorporated is a 30 V, 10 A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK package, featuring 0.55 V forward voltage at 5.0 A per element, 125 A non-repetitive surge rating, and guard ring die construction for transient protection. It is used in low-voltage, high-frequency inverters and polarity protection circuits.

For engineers reviewing the SBG1030CT-T-F datasheet, SBG1030CT-T-F pinout, SBG1030CT-T-F application, or SBG1030CT-T-F equivalent, key selection criteria include its 30 V reverse voltage rating, dual common-cathode configuration, thermal resistance of 3.0 °C/W, and RoHS-compliant tin finish on solderable terminals.

Technical Context

This dual-element Schottky rectifier integrates two anodes sharing one cathode terminal, enabling synchronous rectification or dual-path DC output in compact power supplies. Its guard ring die structure enhances ruggedness against voltage transients without external clamping components.

Designed for operation up to 125 °C junction temperature, it delivers low conduction loss (V_F = 0.55 V @ 5 A) and fast switching with 275 pF typical junction capacitance at 4 V reverse bias and 1 MHz - critical for high-frequency flyback and LLC resonant converters.

FAQ

Is SBG1030CT-T-F pin-compatible with SBG1040CT-T-F?

No. While both share the D²PAK package and dual common-cathode pinout (pins 1 and 3 = anodes, pin 2 = cathode), SBG1040CT-T-F has a 40 V peak reverse voltage rating versus 30 V for SBG1030CT-T-F. Substitution requires verification of reverse voltage margin in the target circuit to avoid avalanche breakdown.

What is the thermal pad connection requirement for SBG1030CT-T-F?

The D²PAK package includes an exposed thermal pad (pin 2, common cathode) that must be soldered to a minimum 200 mm² copper pour with ≥4 thermal vias (0.3 mm diameter) to an internal ground plane. This ensures the specified 3.0 °C/W R_θJC and prevents junction overheating above 8 A continuous load.

Does SBG1030CT-T-F support lead-free reflow assembly?

Yes. The device features a lead-free, RoHS-compliant tin finish on all terminals and is qualified for standard Pb-free reflow profiles (peak temperature ≤ 260 °C, 60-second duration). Moisture sensitivity level is rated at Level 1 per J-STD-020C, eliminating bake requirements prior to assembly.

Why is SBG1030CT-T-F marked "NOT RECOMMENDED FOR NEW DESIGN"?

Diodes Incorporated issued this notice due to planned obsolescence: newer alternatives like the SBRA1030CT offer identical electrical specs with enhanced surge robustness and tighter V_F distribution. Existing designs may continue using SBG1030CT-T-F, but new projects should evaluate SBRA1030CT or APD1030CT for extended longevity and improved parametric consistency.
