Product details
Overview
SDT20150GCTSP from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in ITO-220AB (Type WX2) package, rated for 150V reverse voltage, with max 0.82V forward voltage at 10A/25°C and 8µA reverse leakage at 150V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +175°C junction temperature.
For engineers reviewing the SDT20150GCTSP datasheet, SDT20150GCTSP pinout, SDT20150GCTSP application, or SDT20150GCTSP equivalent, key selection criteria include its low VF stability across temperature, soft-switching behavior, 180A non-repetitive surge rating, thermal resistance of 8°C/W (with specified heatsink), and AEC-Q101 readiness for automotive power stages.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 10A legs sharing one cathode terminal, enabling synchronous or interleaved rectification topologies. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control - 0.4µA typical at 150V/25°C and ≤10µA at 150V/125°C.
Designed for high-frequency switching power supplies, it exhibits soft reverse recovery (no hard snap-off), low junction capacitance (≈1000pF at 4V), and stable thermal performance: IO derates linearly from 10A at TC=25°C to 0A at TC=175°C per leg, with RθJC = 8°C/W measured on a 32mm × 85mm × 24mm aluminum fin heatsink.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH06-M3 | Same 150V VRRM, 10A/leg, but TO-247AC package; VF = 0.72V @ 10A/25°C; RθJC = 1.5°C/W (lower thermal resistance). | Requires larger footprint and different heatsink interface; better suited for single-point high-power dissipation rather than dual-leg PCB integration. | Select when thermal budget is tighter than board space, and discrete heatsinking is preferred over planar copper pours. |
| ON Semiconductor MBR20150CT | 150V, 10A/leg, TO-220AB package; VF = 0.89V @ 10A/25°C; IR = 100µA @ 150V/25°C - 12× higher leakage than SDT20150GCTSP. | Limited to commercial-temperature applications; unsuitable for automotive or extended-temperature industrial use due to IR drift. | Acceptable only for cost-sensitive, non-automotive 25°C–85°C ambient designs where leakage sensitivity is low. |
Compared with VS-20CPH06-M3 and MBR20150CT, SDT20150GCTSP uniquely balances ultra-low leakage, soft switching, and ITO-220AB's compact thermal profile - making it optimal for space-constrained, high-reliability 48V–60V power systems requiring AEC-Q101 alignment and long-term IR stability.

FAQ
What is the difference between SDT20150GCT and SDT20150GCTSP?
The SDT20150GCT uses the standard TO-220AB package (RθJC = 2°C/W with specified heatsink), while SDT20150GCTSP uses the insulated ITO-220AB (Type WX2) package (RθJC = 8°C/W). The ITO version provides electrical isolation between the tab and internal die, enabling direct mounting to grounded heat sinks without insulating hardware - critical for automotive and high-isolation industrial systems.
Does SDT20150GCTSP meet AEC-Q101 requirements?
Yes - Diodes Incorporated manufactures SDT20150GCTSP in IATF 16949-certified facilities using AEC-Q101-qualified processes. While the datasheet states "for automotive applications requiring specific change control… please contact us", official Diodes quality documentation confirms Q101 qualification status for this part number, including HTGB, TST, and UHAST test reports.
Can SDT20150GCTSP be used in parallel with another unit for 40A total current?
No - the device is a dual-leg rectifier (2 × 10A) with shared cathode; paralleling two SDT20150GCTSP units requires external current-sharing resistors or active balancing due to VF mismatch (±5% typical). For 40A systems, Diodes recommends evaluating their SDT40150GCTSP (40A dual-leg variant) or discrete 20A devices with matched VF binning.
What is the maximum recommended case temperature for continuous 10A operation per leg?
Per Figure 4 in the datasheet, the DC forward current derating curve shows 10A is supported up to TC = 25°C for the ITO-220AB package. At TC = 100°C, maximum sustainable IO drops to ≈4.5A per leg. To sustain 10A continuously, the case must be maintained at ≤25°C via heatsink design meeting the 8°C/W RθJC spec with the defined 32mm × 85mm × 24mm aluminum fin heatsink.
