Product details
Overview
SDT20B60VCTFP from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in ITO-220AB package, rated for 60V reverse voltage per leg, with max 0.60V forward voltage at 10A/25°C and 100µA reverse leakage at 60V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT20B60VCTFP datasheet, SDT20B60VCTFP pinout, SDT20B60VCTFP application, or SDT20B60VCTFP equivalent, key selection criteria include its low VF stability across temperature, soft switching behavior, ITO-220AB thermal resistance (4°C/W), and AEC-Q200 readiness for automotive power supplies.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 10A legs sharing one cathode terminal, enabling synchronous rectification or dual-output DC-DC topologies. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control up to +125°C.
Thermal performance is defined by RθJC = 4°C/W (ITO-220AB), validated with a 50mm × 50mm × 23mm aluminum heatsink. The device exhibits soft reverse recovery with no stored charge, eliminating snubber requirements in high-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operation in 48V bus systems with margin. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; supports 20A total dual-leg output in parallel configurations. |
| VF @ 10A/25°C | 0.60 V - Confirmed max forward drop; enables >92% efficiency in 12V-output buck converters at full load. |
| IR @ 60V/25°C | 100 µA - Max reverse leakage per leg; ensures minimal standby loss in always-on power rails. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance (ITO-220AB); allows 35W dissipation with 140°C ΔT to heatsink. |
| TJ Range | –55°C to +150°C - Full operational junction temperature range; qualified for under-hood automotive environments. |
| IFSM | 140 A - Non-repetitive surge rating (8.3ms half-sine); withstands inrush in server PSU front-ends. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with plastic barrier between mounting tab and internal leads; UL 94V-0 rated molded compound; matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Anode 1) | Anode of Leg 1 | Electrically isolated metal tab; mounted to heatsink without insulator; carries full 10A forward current. |
| Lead 1 (Anode 2) | Anode of Leg 2 | Second anode terminal; enables independent input routing for dual-output or interleaved designs. |
| Lead 2 (Cathode) | Common Cathode | Shared cathode node for both legs; simplifies PCB layout in center-tapped or dual-winding transformer outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.08V vs. planar equivalents at 10A, directly lowering conduction loss in high-current paths. |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0); eliminates switching spikes and EMI in >300kHz DC-DC converters. |
| High-temperature IR stability | IR = 30µA @ 60V/125°C - only 3× increase over 25°C, preserving efficiency in thermally constrained enclosures. |
| RoHS & Halogen-free | Meets EU RoHS 3 (2015/863/EU) and Diodes' "Green" standard (<900ppm Br+Cl, <1000ppm Sb); compliant for automotive Tier-1 supply chains. |
Applications
| Server VRMs | Automotive ADAS Power Supplies |

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-20BQ060-M3/45 | Same 60V/10A per leg, but TO-220AC package (RθJC = 3.5°C/W); VF = 0.62V @ 10A/25°C. | Higher thermal conductivity but non-isolated tab requires mica insulator; unsuitable for direct heatsink mounting. | Select when board-level isolation is already implemented and lower RθJC justifies added assembly step. |
| ON Semiconductor MBR2060CT | 60V/10A dual, TO-220AB package; VF = 0.75V @ 10A/25°C; IR = 200µA @ 60V/25°C. | Higher VF increases conduction loss by 1.5W per leg; wider IR spread reduces reliability in high-temp industrial use. | Acceptable for cost-sensitive consumer adapters where 150°C operation is not required. |
Compared with VS-20BQ060-M3/45 and MBR2060CT, SDT20B60VCTFP offers superior thermal interface simplicity (isolated tab), tighter IR control at elevated temperature, and lower VF-making it optimal for space-constrained, high-reliability automotive and industrial DC-DC designs.

FAQ
Is SDT20B60VCTFP pin-compatible with standard TO-220AB dual diodes?
No. SDT20B60VCTFP uses the ITO-220AB package, which features an electrically insulated metal tab. Unlike TO-220AB, its tab is not internally connected to any lead-enabling direct heatsink mounting without insulators. Pin assignment (Anode1–Anode2–Cathode) matches industry-standard dual common-cathode layouts, but mechanical mounting differs.
What is the maximum continuous case temperature for reliable operation?
The device supports continuous operation up to TC = +135°C when mounted on a 50mm × 50mm × 23mm aluminum heatsink, based on RθJC = 4°C/W and TJ(max) = +150°C. Derating curves in Figure 4 confirm 10A per leg is sustainable at TC = +125°C, making it suitable for sealed automotive enclosures.
Does SDT20B60VCTFP meet AEC-Q200 requirements?
While not pre-qualified as a standalone AEC-Q200 part, SDT20B60VCTFP is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Diodes states it is intended for automotive applications requiring AEC-Q200 compliance; qualification testing must be performed at system level per customer requirements.
Can this device replace a single 20A Schottky in a center-tapped transformer design?
No-it is a dual-leg 10A-per-leg device with common cathode. In center-tapped configurations, it replaces *two* separate 10A Schottkys (one per half-secondary), not a single 20A unit. Its dual-anode topology matches center-tapped rectification, but total output current remains 10A per leg unless paralleled externally.
