Diodes Incorporated SBG1630CT-T-F

Overview

SBG1630CT-T-F from Diodes Incorporated is a 16A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK package, rated for 30V peak repetitive reverse voltage and 0.55V forward voltage at 8.0A per element, used in low-voltage DC-DC converter output stages and polarity protection circuits.

For engineers reviewing the SBG1630CT-T-F datasheet, SBG1630CT-T-F pinout, SBG1630CT-T-F application, or SBG1630CT-T-F equivalent, key selection criteria include its 175A non-repetitive surge rating, 3.0°C/W junction-to-case thermal resistance, 275pF typical capacitance at 1MHz, and RoHS-compliant tin-plated terminals suitable for automated reflow assembly.

Technical Context

This dual Schottky rectifier integrates two independent anode elements sharing a common cathode terminal, enabling synchronous rectification or dual-output DC-DC conversion without external parallel diodes. Its guard ring die construction provides inherent transient voltage suppression capability.

The device operates across –65°C to +125°C junction temperature range with derated average current (16A at TC = 95°C), and exhibits low conduction loss due to metal-semiconductor junction physics - confirmed by 0.55V V_F at 8.0A and 25°C, and 1.0mA peak reverse leakage at rated 30V blocking.

FAQ

What does "NOT RECOMMENDED FOR NEW DESIGN" mean for SBG1630CT-T-F?

This designation indicates Diodes Incorporated has superseded the SBG1630CT-T-F with newer-generation Schottky rectifiers offering improved thermal performance or lower forward voltage. It remains fully manufacturable and supported for existing designs, with no announced obsolescence date or last-time-buy requirement.

Can SBG1630CT-T-F be used in place of SBG1635CT-T-F or SBG1640CT-T-F?

No - the SBG1630CT-T-F is rated for 30V V_RRM, while SBG1635CT-T-F and SBG1640CT-T-F are rated for 35V and 40V respectively. Substitution requires verification that system reverse voltage never exceeds 30V, as overvoltage may cause premature breakdown and catastrophic failure.

Is the D²PAK package of SBG1630CT-T-F compatible with standard TO-263 footprints?

Yes - the D²PAK (TO-263AB) footprint matches JEDEC MO-211 standard, with identical pad layout, thermal pad dimensions, and pin spacing. PCB land patterns designed for TO-263 devices will accept SBG1630CT-T-F without modification.

Does SBG1630CT-T-F require a heatsink in 16A continuous operation?

Yes - at 16A average current and 95°C case temperature, thermal calculations using R_θJC = 3.0°C/W show junction temperature exceeds 125°C without heatsinking. A minimum 15 cm² copper pour or bolted aluminum heatsink is required to maintain safe operating temperature.
