Product details
Overview
SDT30100CTFP from Diodes Incorporated is a 30A dual common-cathode trench Schottky rectifier in ITO-220AB package, rated for 100V reverse voltage, with max 0.75V forward voltage at 15A/25°C and 100µA reverse leakage at 100V/25°C; used as freewheel or output rectifier in high-efficiency DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT30100CTFP datasheet, SDT30100CTFP pinout, SDT30100CTFP application, or SDT30100CTFP equivalent, key selection criteria include thermal resistance (4°C/W junction-to-case), high-temperature leakage stability (20µA @ 100V/125°C), soft switching behavior, and RoHS-compliant green packaging with matte tin terminals.
Technical Context
This dual-leg Schottky rectifier integrates two independent 15A-rated anode-cathode junctions sharing a common cathode terminal, enabling synchronous or interleaved rectification topologies. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control up to +150°C junction temperature.
The device operates with no minority-carrier storage delay, supporting fast-switching power stages up to several hundred kHz. Thermal performance is defined for ITO-220AB mounting on a 50mm×50mm×23mm aluminum heatsink, where RθJC = 4°C/W enables sustained 30A total conduction under forced-air or moderate heatsink conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse blocking voltage per leg; defines safe operating margin against voltage transients in buck or flyback secondary windings. |
| IO (per leg) | 15 A - Continuous average forward current rating per anode leg at TA = +25°C; supports 30A total dual-leg output in well-cooled designs. |
| VF max | 0.75 V @ 15A, +25°C - Peak forward drop determining conduction loss; contributes ≤11.25W total resistive loss at full load before thermal derating. |
| IR max | 100 µA @ 100V, +25°C - Reverse leakage limiting standby power loss; rises to 20 µA at +125°C, confirming stable high-temp operation. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance for ITO-220AB package; enables direct heatsink mounting without insulating pads for optimal thermal transfer. |
| TJ range | –55°C to +150°C - Full operational junction temperature span; supports industrial and automotive under-hood environments without derating below –40°C. |
Pinout & Package
SDT30100CTFP uses the ITO-220AB surface-mount-compatible through-hole package with three terminals: two anodes (A1, A2) and one common cathode (K). The case is electrically isolated, allowing direct heatsink attachment without insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | First Schottky junction input; connects to transformer secondary or switch node in dual-phase rectification. |
| A2 | Anode 2 | Second independent Schottky junction input; enables interleaved or parallel rectifier configurations. |
| K | Common Cathode | Shared output node; routes combined DC output current to filter capacitor or load rail with minimal parasitic inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.15V vs. planar equivalents at 15A, directly lowering conduction loss in high-current DC-DC stages. |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0); eliminates switching spikes and EMI in high-frequency SMPS layouts. |
| High-temperature IR stability | Leakage remains ≤20 µA at 100V/125°C - critical for maintaining efficiency in enclosed, thermally constrained adapters. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 2 and JEDEC J-STD-709B; contains <900ppm Br+Cl and <1000ppm Sb - compliant for global industrial and consumer shipments. |
Applications
| Server VRM Output Rectification | Industrial AC-DC Adapter |

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-30CPH01-M3 | Same 100V/30A rating, TO-247AC package, RθJC = 2.5°C/W; VF = 0.72V @ 15A but higher IR (250µA @ 100V/25°C). | Better thermal performance but larger footprint; requires insulated mounting due to conductive case. | Select when board space permits and junction temperature must stay <110°C under natural convection. |
| ON Semiconductor MBR30100CT | 100V/30A, TO-220AB package, VF = 0.82V @ 15A, IR = 200µA @ 100V/25°C; no trench process. | Higher conduction loss (+1.05W extra at 15A); less stable leakage above 85°C. | Acceptable for cost-sensitive, lower-ambient applications where efficiency >92% is not required. |

FAQ
Is SDT30100CTFP pin-compatible with standard TO-220AB dual Schottky rectifiers?
No - SDT30100CTFP uses the ITO-220AB package, which has identical pin spacing (2.54 mm e, 5.08 mm e1) but a thinner profile and non-conductive case versus TO-220AB. Mounting holes align, but thermal pad contact area differs; mechanical fit requires verification against ITO-220AB footprint.
What is the maximum recommended case temperature for continuous 30A operation?
Per Figure 4, the DC forward current derating curve shows 30A is supported up to TC = +85°C for ITO-220AB. Above that, current must be linearly reduced to 0A at +150°C; sustained 30A requires active cooling or heatsink design ensuring TC ≤ +80°C.
Does SDT30100CTFP support reflow soldering?
Yes - the matte tin finish on copper leadframe meets MIL-STD-202 Method 208 and is qualified for lead-free reflow profiles (peak 260°C, 10s max). ITO-220AB's plastic body is rated UL 94V-0 and withstands standard Pb-free reflow without delamination or warping.
How does the trench structure improve performance over conventional Schottky rectifiers?
The trench geometry increases effective junction area while shortening carrier transport paths, yielding lower VF (0.75V vs. typical 0.82V) and improved IR uniformity across temperature. This results in tighter parametric distribution and predictable efficiency degradation up to +150°C junction temperature.
