Diodes Incorporated SDT20A60VCTFP

Overview

SDT20A60VCTFP from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in ITO220AB package, rated for 60V reverse voltage per leg, with max 0.57V forward voltage at 10A/25°C and 0.49V at 10A/125°C, delivering low conduction loss and high-temperature leakage stability (0.2mA @ 60V/25°C). It serves as a freewheel or output rectifier in high-efficiency DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT20A60VCTFP datasheet, SDT20A60VCTFP pinout, SDT20A60VCTFP application, or SDT20A60VCTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), soft switching behavior, AEC-Q101 readiness, RoHS/Green compliance, and ITO220AB mechanical compatibility with heatsink mounting.

Technical Context

This dual-diode Schottky rectifier integrates two independent 10A legs in a single ITO220AB thermally enhanced package, enabling synchronous or interleaved rectification topologies without cross-conduction risk. Each leg operates with fully isolated terminals and shares no internal connection between anodes or cathodes.

Its trench MOS structure delivers stable VF across temperature (0.41–0.57V range) and ultra-low IR drift (≤50μA @ 60V/125°C), critical for maintaining efficiency in automotive under-hood power supplies and industrial SMPS where ambient temperatures exceed 85°C.

Key Specifications

Pinout & Package

FAQ

Is SDT20A60VCTFP pin-compatible with standard TO-220AB dual diodes?

No-SDT20A60VCTFP uses the ITO220AB package, which has identical pin spacing but a thinner profile, modified tab geometry, and higher thermal conductivity than generic TO-220AB. Mechanical fit requires verification against ITO220AB outline drawings; thermal pad contact area differs.

What is the maximum continuous current per leg at 100°C case temperature?

Per Figure 4 in DS42107 Rev. 4, the derated IO per leg is 8.5A at TC = 100°C. This value is derived from the linear derating curve starting at 10A at TC = 100°C (not 25°C), confirming usable current remains above 8A even in thermally demanding environments.

Does SDT20A60VCTFP meet AEC-Q101 requirements?

SDT20A60VCTFP is manufactured in IATF 16949-certified facilities and supports PPAP documentation; however, Diodes states formal AEC-Q101 qualification requires customer-specific engagement and test program execution. The device's construction, materials, and thermal robustness align with AEC-Q101 stress categories.

Can both legs be paralleled for a single 20A output path?

Yes-both legs share identical electrical characteristics (VF, IR, TJ max) and are fully isolated. Paralleling A1+A2 and K1+K2 yields 20A total average current capacity with matched thermal distribution, provided PCB layout maintains symmetrical trace impedance and thermal coupling to the heatsink.
