Product details
Overview
SDT20100CTFP from Diodes Incorporated is a 20A dual common-cathode Trench Schottky rectifier in ITO-220AB package, rated for 100V peak reverse voltage, with max 0.71V forward voltage at 10A/25°C and 80µA reverse leakage at 100V/25°C - deployed as freewheel and output rectifier in high-efficiency DC-DC converters.
For engineers reviewing the SDT20100CTFP datasheet, SDT20100CTFP pinout, SDT20100CTFP application, or SDT20100CTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), high-temperature leakage stability (20mA at 100V/125°C), soft switching behavior, and ITO-220AB mounting compatibility with standard heatsinks.
Technical Context
This dual-diode Schottky rectifier uses trench MOS-based anode structures to achieve low VF while maintaining superior IR stability across -55°C to +150°C operating range. Its soft recovery minimizes EMI in switching power supplies without requiring snubbers.
The device is configured as two independent 10A legs sharing a common cathode terminal, enabling synchronous rectification or dual-output DC-DC topologies. Thermal performance is validated with a 50mm × 50mm × 23mm aluminum heatsink per leg.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage per leg; defines safe operation in 48V bus and PoE++ systems. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg at TA=25°C; supports 20A total device rating with shared cathode. |
| VF max | 0.71 V @ 10A, 25°C - Low conduction loss enables >95% efficiency in 12V→5V/3.3V buck converters. |
| IR max | 80 µA @ 100V, 25°C - Tight leakage spec ensures minimal standby power loss in always-on power rails. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB package; enables 150°C max junction temp with 110°C case temp. |
| TJ range | -55°C to +150°C - Full automotive-grade temperature capability without derating up to 125°C ambient. |
| IFSM | 150 A - Non-repetitive surge rating supports inrush current handling during cold-start in industrial SMPS. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with internal isolation barrier between leads and metal tab; allows direct heatsink mounting without insulating washer. Tab is electrically connected to cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first Schottky diode leg | Connects to input/high-side node in buck or flyback secondary; requires PCB copper pour for thermal relief. |
| Pin 2 (Cathode) | Common cathode for both diode legs | Electrically tied to metal tab; serves as output/return path; must be thermally anchored to heatsink. |
| Pin 3 (Anode B) | Anode of second Schottky diode leg | Enables dual-output or interleaved rectification; independent control of two power paths. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.60 V typ @ 10A/125°C - Reduces conduction loss by ≥30% vs planar Schottkys in high-temp operation. |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0) - Eliminates switching spikes and reduces EMI filter burden in MHz-range converters. |
| High-temperature leakage stability | 20 mA IR @ 100V/125°C - Enables reliable operation in under-hood automotive DC-DC modules without thermal runaway. |
| Lead-free & halogen-free | RoHS 3 compliant, <900 ppm Br+Cl, <1000 ppm Sb - Meets IPC-1752A material declaration requirements for Tier-1 automotive supply chain. |
| Automotive-ready qualification | AEC-Q101 qualified (per Diodes' product definitions); manufactured in IATF 16949-certified facility - supports PPAP documentation for automotive OEM programs. |
Applications
| Server VRM Output Rectification | Industrial 48V DC-DC Converter |
|---|---|
Use Scenario: High-current, high-frequency buck converter supplying CPU core voltage (0.8–1.2V @ up to 200A). IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFETs in secondary-side topology; common-cathode configuration simplifies gate drive layout. Use Value: 0.65V VF @ 10A/125°C minimizes power loss in compact VRM designs where thermal headroom is constrained. |
Use Scenario: Isolated 48V-to-12V/5V DC-DC module for PLC backplanes and motor drives. IC Role / Device Role / Timing Role: Output rectifier in active-clamp forward or LLC resonant converter; handles continuous 10A per rail with shared thermal path. Use Value: 4°C/W RθJC enables stable operation at 85°C ambient without forced air, reducing system cooling cost. |
| Automotive ADAS Power Supply | Telecom PoE++ PSE Rectification |
Use Scenario: 12V auxiliary supply for radar ECU and camera modules in ADAS domain controller. IC Role / Device Role / Timing Role: Freewheel diode in boost-derived 5V/3.3V LDO pre-regulator; operates continuously at 105°C under hood. Use Value: 20mA IR @ 100V/125°C prevents thermal runaway during extended high-temp soak testing per ISO 16750-4. |
Use Scenario: Secondary-side rectification in IEEE 802.3bt Type 4 (90W) PoE++ power sourcing equipment. IC Role / Device Role / Timing Role: Dual-leg rectifier for center-tapped transformer output; supports dual 45W channels with shared cathode return. Use Value: Soft switching eliminates need for RC snubbers on transformer secondary, improving power density and reliability. |
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-20CTH02-M3/45 | Same 100V/20A rating, but TO-220AC package (non-isolated tab); RθJC = 3.5°C/W; VF = 0.75V @ 10A/25°C. | Requires insulating pad for heatsink mounting; higher VF increases conduction loss in thermally constrained designs. | Select when lower thermal resistance is critical and isolation is handled externally via bushing or ceramic pad. |
| ON Semiconductor MBR20100CT | 100V/20A, TO-220AB package; VF = 0.82V @ 10A/25°C; IR = 100µA @ 100V/25°C; no AEC-Q101 claim. | Higher VF and leakage reduce efficiency in high-temp, high-reliability applications; lacks automotive qualification documentation. | Acceptable for commercial-grade AC-DC adapters where cost is prioritized over thermal performance and qualification traceability. |
Compared with VS-20CTH02-M3/45 and MBR20100CT, SDT20100CTFP delivers lower forward voltage at elevated temperature, guaranteed ITO-220AB isolation, and documented AEC-Q101 readiness - making it preferred for automotive and industrial systems requiring long-term thermal stability and supply-chain compliance.

FAQ
Is SDT20100CTFP pin-compatible with SDT20100CT?
Yes - both share identical ITO-220AB pinout (Anode A / Cathode / Anode B) and mechanical footprint. The "FP" suffix denotes ITO-220AB (Type HE) variant with enhanced thermal pad geometry and tighter dimensional tolerances, but electrical and mounting compatibility is maintained.
What is the maximum continuous current per leg at 100°C case temperature?
Per Figure 4 in DS38470 Rev. 9-2, the derated IO is 7.5A per leg at TC = 100°C for ITO-220AB packages. This assumes use of the specified 50mm × 50mm × 23mm Al heatsink and natural convection cooling.
Does SDT20100CTFP support automotive qualification out-of-the-box?
SDT20100CTFP is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements. While not pre-certified as a complete part number, Diodes confirms it is PPAP-capable and supports automotive change control - qualification documentation is available upon request.
Can the common cathode be used as a single 20A output node?
No - the device contains two independent 10A Schottky junctions sharing one cathode terminal. Total device current is limited to 20A only if both legs carry equal current; asymmetric loading must respect 10A per leg absolute maximum rating to avoid thermal imbalance and premature failure.
