Product details
Overview
SDT10A60VCT from Diodes Incorporated is a 10A dual common-cathode Trench Schottky rectifier rated for 60V reverse voltage, with 0.54V max forward voltage at 5A/25°C and 100µA max reverse leakage at 60V/25°C. It delivers low conduction loss and high-temperature stability in TO220AB packaging, ideal for DC-DC converter output rectification and freewheeling in automotive-grade power supplies.
For engineers reviewing the SDT10A60VCT datasheet, SDT10A60VCT pinout, SDT10A60VCT application, or SDT10A60VCT equivalent, key selection criteria include per-leg 5A average current rating, thermal resistance of 2°C/W (TO220AB), soft switching behavior, AEC-Q101 readiness, and compatibility with high-efficiency 12V–48V intermediate bus architectures.
Technical Context
This dual-diode device integrates two independent 60V/5A Schottky junctions sharing a common cathode terminal, enabling synchronous rectification or dual-output configurations. Its Trench process architecture achieves lower VF and superior IR stability versus planar Schottkys-especially at TJ = 125°C, where VF remains ≤0.45V and IR stays ≤30µA.
The device operates across –55°C to +150°C junction temperature range and supports non-repetitive surge currents up to 140A (8.3ms half-sine). Thermal design relies on direct case-to-heatsink conduction via the metal tab, with RθJC = 2°C/W specified under 50mm × 50mm × 23mm Al heatsink conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating margin against voltage transients in 48V systems. |
| IO (per leg) | 5 A - Continuous average forward current per diode leg at TC = 75°C; enables 10A total dual-leg output with shared cathode layout. |
| VF max | 0.54 V @ 5A, 25°C - Low conduction loss reduces power dissipation by >30% vs. standard silicon rectifiers in 5–10A DC-DC stages. |
| IR max | 100 µA @ 60V, 25°C - Ultra-low leakage preserves efficiency in standby modes and high-temperature environments (>100°C). |
| RθJC | 2 °C/W - Thermal resistance from junction to case (TO220AB); allows ~25W dissipation with 50°C rise above heatsink temperature. |
| IFSM | 140 A - Peak non-repetitive surge current handling; supports inrush and fault-current robustness in industrial SMPS designs. |
| TJ range | –55°C to +150°C - Full automotive-grade operating envelope; validated for under-hood and engine-control module deployment. |
Pinout & Package
Package: TO220AB (Generic), epoxy-molded plastic with UL 94V-0 rating; metal tab serves as cathode terminal and thermal path. Matte tin-plated copper leadframe ensures MIL-STD-202-compliant solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first Schottky leg | Connects to input/high-side node in freewheeling or rectifier configuration; isolated from Pin 2. |
| Pin 2 (Cathode) | Common cathode for both legs | Electrically and thermally tied to metal tab; must be mounted to heatsink for thermal management and circuit return path. |
| Pin 3 (Anode B) | Anode of second Schottky leg | Enables dual-output or phase-split rectification; electrically independent from Pin 1 but shares cathode reference. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF ≤ 0.45V @ 5A/125°C - Reduces conduction loss by ≥40% vs. legacy Schottkys, directly improving 12V→3.3V buck converter efficiency. |
| Soft, fast switching capability | Negligible reverse recovery charge (QRR ≈ 0) - Eliminates switching spikes and EMI in high-frequency (≥300kHz) topologies without snubbers. |
| High-temperature leakage stability | IR ≤ 30µA @ 60V/125°C - Maintains regulation integrity in automotive cabin modules where ambient exceeds 85°C. |
| AEC-Q101 qualified | Qualified per stress test requirements for discrete semiconductors - Enables use in safety-critical automotive power rails without additional qualification overhead. |

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-10BQ060-M3 | Same 60V/10A dual common-cathode rating; VF = 0.55V @ 5A/25°C; RθJC = 2.5°C/W (TO220AC). | Higher thermal resistance limits continuous power in compact heatsink layouts; no AEC-Q101 documentation published. | Select when cost sensitivity outweighs automotive qualification or marginal thermal headroom is acceptable. |
| ON Semiconductor MBR1060CT | 60V/10A dual Schottky; VF = 0.75V @ 5A/25°C; IR = 500µA @ 60V/25°C; RθJC = 3.0°C/W. | Higher VF increases conduction loss by ~39%; elevated IR degrades light-load efficiency and high-temp reliability. | Acceptable only in non-automotive, non-thermal-constrained applications where legacy stock or dual sourcing is required. |
Compared with VS-10BQ060-M3 and MBR1060CT, SDT10A60VCT provides superior thermal performance (2°C/W), tighter leakage control (100µA vs. 500µA), and documented AEC-Q101 compliance-making it the preferred choice for automotive and high-reliability industrial power conversion where efficiency, temperature margin, and qualification traceability are critical.

FAQ
What is the maximum junction temperature and how is it validated?
The SDT10A60VCT is rated for continuous operation from –55°C to +150°C junction temperature. This range is validated per AEC-Q101 stress tests including high-temperature operating life (HTOL), temperature cycling, and unbiased highly accelerated stress testing (uHAST), with all electrical parameters meeting specification limits after exposure.
Is the metal tab electrically isolated from the anode pins?
No-the metal tab is internally connected to Pin 2 (common cathode) and is not electrically isolated. It must be mounted to a grounded or cathode-referenced heatsink. Insulating hardware (e.g., shoulder washers or mica pads) is required if the heatsink is at a different potential than the cathode net.
Does SDT10A60VCT support surface-mount reflow assembly?
No-SDT10A60VCT uses through-hole TO220AB packaging and is not designed for SMT reflow. Its thermal pad requires mechanical screw or clip attachment to a heatsink. For SMT alternatives, consider Diodes' APD10A60U (PowerDI5060) or similar DFN-packaged trench Schottkys.
How does its soft switching behavior reduce EMI in high-frequency converters?
As a Schottky diode, SDT10A60VCT has no minority-carrier storage or reverse recovery time (trr ≈ 0 ns), eliminating the high di/dt current spike and associated ringing that occurs during turn-off in PN junction rectifiers-directly reducing broadband conducted and radiated EMI in 300–1000kHz switch-mode power supplies.
