Diodes Incorporated SDT10100CT

Overview

SDT10100CT from Diodes Incorporated is a 10A dual common-cathode Trench Schottky rectifier in TO220AB package, rated for 100V reverse voltage per leg, with max 0.76V forward voltage at 5A/25°C and 50µA reverse leakage at 100V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT10100CT datasheet, SDT10100CT pinout, SDT10100CT application, or SDT10100CT equivalent, key selection criteria include thermal resistance (2°C/W junction-to-case), soft switching behavior, high-temperature leakage stability up to +125°C, and AEC-Q200 readiness for automotive power supplies.

Technical Context

This dual-leg Schottky diode uses trench MOS structure to achieve low VF and minimal reverse recovery charge. Each anode operates independently with shared cathode, enabling synchronous rectification or dual-output DC-DC topologies without cross-conduction risk.

Its thermal design supports 10A total average current with heatsink (5A per leg), and leakage remains under 10µA at 100V/125°C - critical for high-ambient industrial and automotive power stages where thermal runaway must be avoided.

Key Specifications

FAQ

Is SDT10100CT pin-compatible with MBR10100CT?

Yes - both use TO220AB package with identical 3-pin layout (Anode1–Anode2–Cathode). However, SDT10100CT's cathode tab is electrically isolated, while MBR10100CT's tab is internally connected to cathode and requires insulating hardware if mounted to grounded heatsinks.

What is the maximum continuous case temperature for full 10A operation?

Per Figure 4, SDT10100CT supports 5A per leg up to TC = 100°C. At TC = 100°C, total 10A output is achievable with a 2°C/W heatsink and ≤10W total dissipation - verified by thermal testing in Diodes' DS40724 Rev. 4.

Does SDT10100CT meet AEC-Q200 stress test requirements?

No - the device is manufactured in IATF 16949-certified facilities and PPAP-capable, but Diodes does not list AEC-Q200 qualification for SDT10100CT in DS40724. For certified AEC-Q200 parts, contact Diodes directly for qualified variants like SDT10100CTQ.

Can SDT10100CT replace a single 10A Schottky in a center-tapped transformer design?

No - SDT10100CT is a dual common-cathode configuration (not center-tapped). It replaces two discrete 5A Schottkys in independent-leg topologies (e.g., dual-output buck or interleaved flyback), not single-winding full-wave rectification.
