Product details
Overview
SDT10A100CT from Diodes Incorporated is a 10A dual-leg Trench Schottky rectifier in TO220AB package, rated for 100V peak reverse voltage, with max 0.66V forward voltage at 5A/25°C and 50µA reverse leakage at 100V/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 SDT10A100CT datasheet, SDT10A100CT pinout, SDT10A100CT application, or SDT10A100CT equivalent, key selection criteria include its low VF stability across temperature, soft-switching behavior, 150A non-repetitive surge rating, and AEC-Q101 readiness for automotive power stages requiring robust thermal performance and RoHS-compliant lead-free construction.
Technical Context
This dual-anode Schottky rectifier integrates two independent 5A legs in a single TO220AB thermally optimized package, enabling parallel conduction paths without external paralleling. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control up to +125°C.
The device operates with typical thermal resistance RθJC of 2°C/W (TO220AB), supports continuous 10A total output current with derating above +75°C case temperature, and exhibits soft reverse recovery with negligible stored charge-critical for reducing EMI in high-frequency switching supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operation in 48V–72V bus systems with margin. |
| IO (per leg) | 5 A - Continuous average forward current per anode; enables 10A dual-leg output with shared cathode configuration. |
| VF max | 0.66 V @ 5A, 25°C - Low conduction loss reduces heat generation in high-current DC-DC secondary-side rectification. |
| IR max | 50 µA @ 100V, 25°C - Ultra-low leakage preserves efficiency in standby modes and high-temperature environments. |
| IFSM | 150 A - Peak surge capability handles inrush and transient overloads without failure in adapter and converter inputs. |
| RθJC | 2 °C/W - Enables direct heatsink mounting for thermal management in space-constrained industrial power modules. |
| TJ range | −55°C to +150°C - Supports operation in under-hood automotive and industrial ambient conditions without derating. |
Pinout & Package
Package: TO220AB (Generic), 3-terminal through-hole package with isolated tab (cathode-connected tab), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, weight ≈1.85 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | First Schottky junction input; connects to transformer secondary or switch node in synchronous rectifier topology. |

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-10BQ100 | Same 100V/10A rating, but single-die construction; VF = 0.72V @ 5A/25°C; RθJC = 3.0°C/W. | Lacks dual-anode isolation; requires external paralleling for multi-phase use; higher conduction loss. | Select when cost sensitivity outweighs thermal or layout advantages of dual-leg integration. |
| ON Semiconductor MBR10100CT | 100V/10A, VF = 0.75V @ 5A/25°C; RθJC = 2.5°C/W; not AEC-Q101 qualified. | Higher VF increases thermal load in compact enclosures; no automotive qualification documentation available. | Prefer for non-automotive industrial applications where AEC-Q101 is not mandated. |
Compared with VS-10BQ100 and MBR10100CT, SDT10A100CT offers superior thermal resistance (2°C/W), lower VF (0.66V), and documented AEC-Q101 readiness-making it optimal for space-constrained, high-reliability automotive and server power designs demanding minimal conduction loss and proven high-temperature stability.

FAQ
Is SDT10A100CT pin-compatible with standard TO220AB dual-diode rectifiers?
Yes. SDT10A100CT uses the industry-standard TO220AB mechanical outline with Anode–Cathode–Anode pin assignment (left–center–right). Its pinout matches MBR10100CT and SB10100CT, enabling direct PCB footprint reuse without layout changes.
Does SDT10A100CT require a heatsink in 10A continuous operation?
Yes. At 10A total current and 25°C ambient, junction temperature exceeds 150°C without heatsinking. With a 50mm×50mm×23mm aluminum heatsink, RθJC + RθCA ≈ 12°C/W allows safe operation up to ~75°C ambient-verified per Figure 4 derating curve.
What is the significance of "Trench" in SDT10A100CT's technology?
Trench architecture etches vertical MOS-like channels into the silicon, reducing on-resistance and forward voltage versus planar Schottky diodes. This yields 0.66V VF at 5A-12% lower than comparable planar devices-while maintaining tight IR control up to 125°C.
Can SDT10A100CT be used in reverse polarity protection circuits?
Yes. With its 100V VRRM and low 0.66V VF, it functions effectively as a series-blocking diode in 24V–48V systems. Its soft switching avoids voltage spikes during load disconnect, and 150A IFSM handles brief battery-reverse connection events without damage.
