Product details
Overview
SDT30A100CTFP from Diodes Incorporated is a 30A dual common-cathode Trench Schottky rectifier in ITO-220AB package, rated for 100V reverse voltage, 0.73V max forward voltage at 15A/25°C, and 100µA max reverse leakage at 100V/25°C - optimized for high-efficiency DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT30A100CTFP datasheet, SDT30A100CTFP pinout, SDT30A100CTFP application, or SDT30A100CTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), soft fast switching behavior, high-temperature leakage stability (20µA @ 100V/125°C), and AEC-Q101 readiness for automotive power systems.
Technical Context
This dual-diode Schottky rectifier integrates two independent 15A legs sharing a common cathode terminal, enabling synchronous rectification or dual-output DC-DC topologies. Its Trench process delivers lower VF and superior IR stability versus planar Schottkys, especially above 100°C.
Designed for high-frequency switching power supplies, it exhibits soft reverse recovery with minimal ringing and low stored charge (QRR not specified but implied by "soft, fast switching" claim), supporting operation up to several hundred kHz without significant switching loss penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in unidirectional DC bus or flyback clamp circuits. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg at TC = 100°C; supports 30A total device output with shared cathode configuration. |
| VF max | 0.73 V @ 15A, 25°C - Low conduction loss enables >95% efficiency in 12V–48V output converters at full load. |
| IR max | 100 µA @ 100V, 25°C - Ultra-low leakage preserves hold-up time in standby mode and reduces thermal runaway risk in parallel arrays. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance (ITO220AB); enables 200W surge handling with standard heatsinking and simplifies thermal design vs. TO-220AB (2°C/W). |
| TJ range | −55°C to +150°C - Full automotive-grade temperature capability; ensures reliability in under-hood or industrial power supply environments. |
| Switching | Soft, fast recovery - Minimizes EMI and voltage overshoot during turn-off; eliminates need for snubbers in most 200–500 kHz designs. |
Pinout & Package
Package: ITO-220AB - Insulated tab variant with electrically isolated metal tab (no internal connection to any pin), enabling direct mounting to heatsink without insulator washer. Dimensions: 15.87 mm × 10.11 mm × 4.70 mm (L × W × H), weight ≈ 1.90 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | First anode terminal | Connects to input/high-side node of first rectifier leg; requires PCB copper pour for thermal management. |
| Pin 2 (Cathode) | Common cathode | Shared output node for both legs; carries full 30A composite current; must be routed with ≥2 oz copper and thermal vias. |
| Pin 3 (Anode B) | Second anode terminal | Connects to input/high-side node of second rectifier leg; electrically isolated from Pin 1 and Pin 2 except through die. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.62 V typ @ 15A/125°C - Reduces conduction loss by ~30% vs. silicon PN rectifiers, directly improving light-load efficiency. |
| High-temperature leakage stability | 20 µA @ 100V/125°C - Enables reliable operation in sealed enclosures or high-ambient environments without derating. |
| Soft, fast switching | No reverse recovery tail current - Eliminates hard-switching losses and associated EMI in synchronous buck or LLC secondary side. |
| Lead-free & green construction | RoHS 3 compliant, halogen/antimony free (<900 ppm Br+Cl, <1000 ppm Sb) - Meets automotive ELV and industrial environmental compliance mandates. |
| AEC-Q101 qualified | Qualified per AEC-Q101 Rev D - Validated for automotive power modules, engine control units, and ADAS power rails requiring change-controlled manufacturing. |
Applications
| Server VRM Output Stage | Industrial AC-DC Adapter |
|---|---|
|
Use Scenario: High-current, multi-phase buck converter delivering 12V/30A to CPU/GPU VRMs in data center servers. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacing MOSFETs in discrete implementation; operates at 300–600 kHz with zero-voltage switching assist. Use Value: 0.73V VF reduces conduction loss by 1.8W per leg vs. Si diode, lowering thermal density and enabling fanless operation in compact 1U chassis. |
Use Scenario: Universal-input (90–264 VAC), 24V/15A open-frame AC-DC adapter for factory automation controllers. IC Role / Device Role / Timing Role: Output rectifier in active-clamp forward topology; handles continuous 15A per leg with 100°C case temperature. Use Value: 4°C/W RθJC allows direct heatsink mounting without thermal interface material, cutting assembly cost and improving long-term reliability over 10-year field life. |
| Automotive Body Control Module | Telecom DC Power Shelf |
|
Use Scenario: 12V auxiliary power supply in BCM managing lighting, door locks, and HVAC actuators. IC Role / Device Role / Timing Role: Freewheel diode in boost converter feeding 5V/3A microcontroller rail; subjected to load dump transients and −40°C cold cranking. Use Value: −55°C to +150°C rating ensures startup at extreme ambient; soft recovery prevents gate driver coupling noise that could disrupt CAN/LIN communication. |
Use Scenario: −48V DC distribution shelf supplying 12V/20A point-of-load converters across telecom rack. IC Role / Device Role / Timing Role: Blocking diode in OR-ing configuration for redundant power inputs; must sustain 100V reverse bias with <100µA leakage at 70°C ambient. Use Value: 100µA IR max at 25°C and only 20µA at 125°C ensures <0.5W standby dissipation per diode, critical for energy-efficient NEBS-compliant systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH01-M3 | Same 100V/30A rating, TO-247AC package, RθJC = 2.5°C/W, VF = 0.71V @ 15A/25°C, but no AEC-Q101 qualification. | Higher thermal performance but larger footprint; lacks automotive change control and PPAP support. | Select when maximum power density is required and automotive qualification is unnecessary. |
| ON Semiconductor MBR30100CT | 100V/30A, TO-220AB package, VF = 0.75V @ 15A/25°C, IR = 200µA @ 100V/25°C, RθJC = 2°C/W, AEC-Q101 not claimed. | Lower VF tolerance and higher leakage reduce efficiency in thermally constrained designs; no ITO-220AB insulation. | Choose for cost-sensitive industrial applications where heatsink isolation is not required and 125°C leakage is acceptable. |
Compared with VS-30CPH01-M3 and MBR30100CT, SDT30A100CTFP uniquely combines ITO-220AB electrical isolation, AEC-Q101 qualification, and industry-leading 100µA/100V leakage - making it the only option qualified for safety-critical automotive power rails requiring traceable manufacturing and thermal robustness without added insulation hardware.

FAQ
What is the difference between SDT30A100CT and SDT30A100CTFP?
SDT30A100CT uses the standard TO-220AB package with an electrically conductive tab, while SDT30A100CTFP uses the ITO-220AB package with an insulated tab - enabling direct heatsink mounting without thermal washers or isolation pads. Both share identical electrical specs and marking code "SDT30A100CTFP" on the ITO-220AB variant.
Is SDT30A100CTFP qualified for automotive use?
Yes - SDT30A100CTFP is AEC-Q101 qualified, manufactured in IATF 16949-certified facilities, and supports PPAP documentation. It meets automotive requirements for change control, lot traceability, and high-temperature reliability (−55°C to +150°C), making it suitable for BCM, ADAS, and infotainment power supplies.
Can SDT30A100CTFP replace a single 30A Schottky in a common-anode configuration?
No - SDT30A100CTFP is a dual common-cathode device (two anodes, one shared cathode). It cannot substitute for a common-anode part without circuit redesign. For common-anode replacement, consider Diodes' SDT30A100AT (anode-common variant), which has matching ratings and ITO-220AB packaging.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies derating curves showing 15A per leg at TC = 100°C. At TC = 115°C, current must be reduced to ~12A/leg; full 30A composite output is only sustainable up to TC = 100°C with adequate heatsinking (e.g., 50mm × 50mm × 23mm Al heatsink per note 5).
