Product details
Overview
SDT20100GCTFP from Diodes Incorporated is a 20A dual-leg Trench Schottky rectifier in ITO-220AB (Type WX) package, rated for 100V reverse voltage, with max 0.72V forward voltage at 10A/25°C and 30µA leakage at 100V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating under high-temperature conditions.
For engineers reviewing the SDT20100GCTFP datasheet, SDT20100GCTFP pinout, SDT20100GCTFP application, or SDT20100GCTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), soft switching behavior, low VF stability up to +150°C, and AEC-Q101 readiness for automotive power stages.
Technical Context
This dual-diode Schottky rectifier integrates two independent 10A legs in a single ITO-220AB thermally enhanced package. Each leg delivers 100V VRRM, supports 250A non-repetitive surge current, and maintains <0.72V VF at full rated current and room temperature.
Its trench-based structure enables superior high-temperature leakage control-only 12µA at 100V/125°C-and stable junction capacitance (≈1000pF at 0V). The device operates across –55°C to +150°C junction range with no derating required below +125°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operation in 48V–60V bus systems with margin. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; supports 20A total device rating with dual-leg parallel configuration. |
| VF max @ 10A/25°C | 0.72 V - Low conduction loss enabling >94% efficiency in 12V-output buck converters at full load. |
| IR max @ 100V/25°C | 30 µA - Ultra-low reverse leakage preserves standby power integrity in energy-sensitive adapters. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance enables direct heatsink mounting without thermal interface material in space-constrained designs. |
| TJ range | –55°C to +150°C - Full automotive-grade operating envelope validated per AEC-Q101 stress test requirements. |
Pinout & Package
Package: ITO-220AB (Type WX), thermally optimized variant of TO-220 with reduced RθJC (4°C/W vs. 2°C/W for TO220AB) and improved mechanical robustness for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first Schottky diode leg | Connects to switching node in synchronous rectification or flyback secondary; requires low-inductance layout. |
| Pin 2 (Cathode Common) | Shared cathode connection for both legs | Provides single-point output return path; electrically ties both diodes in common-cathode configuration. |
| Pin 3 (Anode 2) | Anode of second Schottky diode leg | Enables dual-output or interleaved converter topologies; isolated anode routing prevents cross-talk. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF drift over temperature and improves IR stability-critical for unregulated 12V rail hold-up in automotive ECUs. |
| Soft, fast switching | Minimizes EMI generation during turn-off; eliminates need for snubbers in 300kHz–1MHz DC-DC designs. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 3 (2015/863/EU) and JEDEC J-STD-020 reflow profile compatibility for lead-free SMT assembly. |
| AEC-Q101 qualified process | Manufactured in IATF 16949-certified facility with PPAP support-enables direct use in ADAS power supplies and body control modules. |
Applications
| Automotive DC-DC Converters | Server PSU Output Rectification |
|---|---|
Use Scenario: 12V-to-5V/3.3V point-of-load conversion in engine control units and infotainment head units. IC Role / Device Role / Timing Role: Freewheel diode in synchronous buck topology, handling 10A continuous current per rail. Use Value: 0.72V VF minimizes conduction loss at high ambient temperatures (up to +105°C under hood), preserving system efficiency. |
Use Scenario: Secondary-side rectification in 48V input server PSUs delivering 50A+ at 12V output. IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier enabling interleaved phase current sharing. Use Value: 4°C/W RθJC allows direct heatsink mounting on compact VRM PCBs without thermal vias or paste. |
| Industrial AC-DC Adapters | Telecom Power Modules |

IC Role / Device Role / Timing Role: Output rectifier in LLC resonant converter secondary stage. Use Value: 30µA IR at 25°C and only 12µA at 125°C ensures <10mW standby loss compliance with Level VI standards. |
Use Scenario: 48V-to-12V intermediate bus converter in 5G base station RF power amplifiers. IC Role / Device Role / Timing Role: High-frequency rectifier operating at 300kHz with minimal reverse recovery charge. Use Value: Soft switching behavior reduces switching node ringing, easing EMI filter design and passing CISPR 32 Class B. |
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-20CPH03-M3 | 30V VRRM, 20A single-anode; higher VF (0.78V @ 10A) but lower RθJC (2.5°C/W). | Limited to ≤24V systems; unsuitable for 48V telecom or automotive 12V bus with transients. | Select when lower thermal resistance is critical and voltage rating can be sacrificed. |
| ON Semiconductor MBR20100CT | 100V VRRM, 20A dual common-cathode; planar Schottky, VF = 0.85V @ 10A, IR = 100µA @ 100V/25°C. | Higher conduction loss and leakage reduce efficiency in high-temp, low-power-loss designs. | Acceptable for cost-sensitive industrial adapters where thermal margin exceeds 20°C. |
Compared with VS-20CPH03-M3 and MBR20100CT, SDT20100GCTFP uniquely balances 100V capability, ultra-low VF, and sub-50µA leakage at elevated temperature-making it optimal for thermally constrained, high-reliability 48V–60V power stages.

FAQ
What is the difference between SDT20100GCT and SDT20100GCTFP?
The SDT20100GCT uses standard TO-220AB packaging (RθJC = 2°C/W), while SDT20100GCTFP uses ITO-220AB (Type WX) with enhanced thermal performance (RθJC = 4°C/W) and tighter dimensional tolerances for automated assembly. Both share identical electrical specs and dual-common-cathode pinout.
Is SDT20100GCTFP qualified for automotive use?
Yes-SDT20100GCTFP is manufactured in IATF 16949-certified facilities and supports AEC-Q101 qualification testing. While the base part is not pre-certified, Diodes provides PPAP documentation and change control for automotive customers upon request.
Can SDT20100GCTFP replace a single 20A Schottky in common-cathode configuration?
Yes-it integrates two 10A Schottky legs with shared cathode (Pin 2), enabling direct substitution for discrete dual-diode solutions in buck, flyback, or interleaved topologies without circuit modification.
What is the maximum allowable case temperature for continuous 10A operation per leg?
Per Figure 5 in DS42544 Rev. 4-2, the SDT20100GCTFP supports 10A per leg continuously up to TC = +125°C. Derating begins above that point, reaching 5A at TC = +150°C for each leg.
