Diodes Incorporated SBG2030CT-T-F

Overview

SBG2030CT-T-F from Diodes Incorporated is a 30 V, 20 A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK (TO-263) package, featuring 0.55 V forward voltage at 10 A per element, 225 A non-repetitive surge rating, and 2.0 °C/W junction-to-case thermal resistance-used in low-voltage DC/DC converter output stages and OR-ing circuits.

For engineers reviewing the SBG2030CT-T-F datasheet, SBG2030CT-T-F pinout, SBG2030CT-T-F application, or SBG2030CT-T-F equivalent, key selection criteria include peak reverse voltage (30 V), average output current (20 A @ TC = 105°C), forward voltage drop, thermal resistance, and D²PAK mounting compatibility with high-power PCB heatsinking.

Technical Context

This dual-element Schottky rectifier integrates two independent anode terminals (Pins 1 and 3) sharing a common cathode (Pins 2 & 4), enabling synchronous OR-ing or dual-phase freewheeling in compact 12 V/24 V power rails. Its guard ring die construction provides inherent transient protection without external TVS devices.

The device operates across –65°C to +150°C junction temperature range, with 650 pF typical junction capacitance at 4 V reverse bias and 1.0 mA peak reverse leakage at 25°C-critical for high-frequency switching efficiency in SMPS and automotive body control modules.

FAQ

Is SBG2030CT-T-F suitable for synchronous rectification in 500 kHz LLC resonant converters?

No-this device is a passive Schottky rectifier, not a synchronous MOSFET driver or controller. While its 650 pF capacitance and 0.55 V VF support operation up to ~300 kHz in hard-switched topologies, it lacks gate drive capability and cannot replace active synchronous rectifiers in LLC designs requiring precise timing control.

What is the minimum recommended copper area for thermal relief when mounting SBG2030CT-T-F on FR-4?

Diodes Incorporated specifies ≥250 mm² of 2 oz copper connected to Pins 2 & 4 (common cathode) via ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). This achieves the rated 20 A current at TC = 105°C; smaller areas require current derating per Figure 1 in DS30091 Rev. 6.

Does SBG2030CT-T-F meet AEC-Q101 for automotive use?

No-SBG2030CT-T-F is not AEC-Q101 qualified. It is rated for –65°C to +150°C operation and used in automotive body electronics, but qualification requires additional stress testing (e.g., HTGB, TCT) not performed on this part. For AEC-Q101 compliance, consider Diodes' APx series Schottky rectifiers.

Can Pin 1 and Pin 3 be paralleled to increase current handling beyond 20 A?

No-Pins 1 and 3 are separate anodes connected to independent die elements sharing one cathode. Paralleling them does not double current capacity due to thermal coupling and mismatched forward characteristics. The 20 A rating applies per element; total package dissipation remains limited by RθJC = 2.0 °C/W and maximum junction temperature.
