Diodes Incorporated SDT30100GCTFP

Overview

SDT30100GCTFP from Diodes Incorporated is a 30A dual-leg trench Schottky rectifier in ITO220AB (Type WX) package, rated for 100V peak reverse voltage per leg, with max 0.77V forward voltage at 15A/25°C and 30µA reverse leakage at 100V/25°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters operating under high-temperature conditions.

For engineers reviewing the SDT30100GCTFP datasheet, SDT30100GCTFP pinout, SDT30100GCTFP application, or SDT30100GCTFP equivalent, key selection criteria include its low VF stability up to +150°C, soft switching behavior, 250A non-repetitive surge rating, and IATF 16949-manufactured qualification for automotive-grade reliability.

Technical Context

This dual-diode Schottky rectifier integrates two independent 15A legs in a single ITO220AB thermally enhanced package, enabling parallel operation or independent circuit paths. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control across temperature - 12mA leakage at 100V/125°C confirms robust high-temperature blocking.

The device exhibits soft reverse recovery with minimal ringing, critical for EMI-sensitive switch-mode power supplies. Thermal resistance of 4°C/W (junction-to-case) allows sustained 30A total output when mounted on an appropriate heatsink, supporting compact, high-power-density converter designs without forced air cooling.

FAQ

What is the difference between SDT30100GCT and SDT30100GCTFP?

SDT30100GCT uses the standard TO220AB package (RθJC = 2°C/W), while SDT30100GCTFP uses the ITO220AB (Type WX) variant with enhanced thermal isolation (RθJC = 4°C/W) and tighter dimensional tolerances. The FP suffix denotes the ITO220AB package; both share identical electrical specs and marking code structure, but differ in thermal performance and mechanical fit.

Can SDT30100GCTFP replace a single 30A Schottky in TO220AB?

Yes - its dual-anode/single-cathode configuration allows use as a single 30A rectifier by connecting both anodes together. However, doing so forfeits the independent leg control benefit. For true 30A single-path replacement, verify that the original design's thermal interface matches ITO220AB's 4°C/W RθJC and mounting hole pattern.

Is SDT30100GCTFP qualified for automotive applications?

Yes - it is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements for discrete semiconductors. While not pre-qualified to full AEC-Q100 system-level standards, its process control, traceability, and PPAP capability make it suitable for automotive power subsystems including BCMs, lighting, and infotainment DC-DC stages.

What is the maximum continuous case temperature for reliable operation?

Per Figure 5 in the datasheet, SDT30100GCTFP supports 15A per leg up to TC = +110°C. At TC = +100°C, derated IO is ~12.5A/leg (25A total). Operation beyond TC = +110°C requires active thermal monitoring or derating to prevent exceeding TJ = +150°C, given its 4°C/W RθJC and typical power dissipation.
