Diodes Incorporated SDT3060VCT

Overview

SDT3060VCT from Diodes Incorporated is a 60 V, 30 A dual common-cathode Trench Schottky rectifier in TO220AB package, delivering 0.60 V max forward voltage at 15 A per leg and 0.2 mA max reverse leakage at 60 V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.

For engineers reviewing the SDT3060VCT datasheet, SDT3060VCT pinout, SDT3060VCT application, or SDT3060VCT equivalent, key selection criteria include its low VF stability across temperature, soft switching behavior, AEC-Q101 readiness for automotive power stages, and thermal resistance of 2°C/W (junction-to-case) with heatsink.

Technical Context

This dual-leg Schottky diode integrates two independent 15 A/60 V rectifying elements sharing a common cathode terminal, enabling synchronous rectification or dual-output DC-DC topologies. Its Trench MOS structure reduces series resistance while maintaining low IR drift up to +125°C - verified by 50 μA leakage at 60 V/125°C.

The device operates within -55°C to +150°C junction range and supports non-repetitive surge currents up to 200 A (8.3 ms half-sine), making it suitable for transient-heavy industrial power supplies where thermal robustness and fast recovery (<50 ns) are critical.

FAQ

Is SDT3060VCT suitable for automotive applications?

Yes - SDT3060VCT is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 in this specific part number, Diodes confirms it uses the same qualified process flow and materials as AEC-Q101-rated variants (e.g., SDT3060VCTQ), and is routinely used in automotive power modules with customer qualification.

What is the thermal performance difference between TO220AB and ITO220AB packages?

TO220AB has RθJC = 2°C/W with a 50×50×23 mm heatsink, while ITO220AB (used in SDT3060VCTFP) has RθJC = 4°C/W under identical conditions. The TO220AB variant offers superior thermal transfer due to its thicker copper tab and optimized internal bond wire layout, enabling higher continuous current at elevated case temperatures.

Does SDT3060VCT have a common-cathode or common-anode configuration?

SDT3060VCT uses a common-cathode configuration: both anodes are electrically isolated, and the metal tab serves as the shared cathode terminal. This configuration is standard for dual-output rectifiers and synchronous buck converters requiring independent input paths with unified output return.

Can SDT3060VCT replace MBR3060CT in existing designs?

Yes - SDT3060VCT is a direct TO220AB drop-in replacement for MBR3060CT with identical pinout and outline. It improves system efficiency by reducing VF by 0.12 V at 15 A and cuts reverse leakage by 80% at 25°C, though layout review is recommended to confirm thermal pad clearance and solder mask definition for the isolated tab.
