Product details
Overview
SDT20A60VCT from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in TO220AB package, rated for 60V VRRM, with max 0.57V forward voltage at 10A/25°C and only 0.2mA 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 under high-temperature conditions.
For engineers reviewing the SDT20A60VCT datasheet, SDT20A60VCT pinout, SDT20A60VCT application, or SDT20A60VCT equivalent, key selection criteria include its low VF stability up to +125°C, soft switching behavior, 200A non-repetitive surge rating, and AEC-Q101 readiness for automotive power stages.
Technical Context
This dual-diode Schottky rectifier integrates two independent 10A legs in a single TO220AB thermally optimized package, enabling parallel operation or dual-rail rectification without external paralleling. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining tight IR control across temperature.
The device exhibits soft reverse recovery (no hard snap-off) and minimal junction capacitance (≈400pF at 4V), making it suitable for high-frequency switching topologies where EMI and switching loss are critical. Thermal resistance RθJC is 2°C/W with standard heatsink, supporting continuous 20A total conduction when properly mounted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum blocking voltage per leg; supports 48V system bus rectification with margin. |
| IO (per leg) | 10 A - Continuous average forward current per diode leg at TC = 75°C; 20A total device rating. |
| VF max | 0.57 V @ 10A, 25°C - Low conduction loss enables >95% efficiency in 12V–48V buck-derived outputs. |
| IR max | 0.2 mA @ 60V, 25°C - Ultra-low leakage preserves standby power in always-on converters. |
| IFSM | 200 A @ 8.3ms - Withstands inrush and transient surges in industrial power supplies without failure. |
| RθJC | 2 °C/W - Enables thermal design with compact heatsinks; junction-to-case path optimized for TO220AB mounting. |
| TJ range | −55°C to +150°C - Qualified for under-hood automotive and industrial environments with full parametric stability. |
Pinout & Package
Package: TO220AB (Generic), 3-terminal through-hole package with isolated tab (cathode-connected tab). Mounting surface is electrically connected to cathode of both diode legs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode Leg 1) | Anode of first Schottky diode | Input terminal for first rectification path; accepts AC or switched node input. |
| Pin 2 (Cathode / Tab) | Common cathode for both legs | Electrically tied to metal tab; must be insulated from chassis unless referenced to system ground. |
| Pin 3 (Anode Leg 2) | Anode of second Schottky diode | Independent input for dual-output or interleaved converter configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF ≤ 0.57V @ 10A/25°C ensures <1.2W conduction loss per leg at full load. |
| High-temperature leakage stability | IR = 50µA @ 60V/125°C - 25× lower than typical Schottkys, critical for hot ambient designs. |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0); eliminates snubber needs and reduces EMI in MHz-range converters. |
| AEC-Q101 qualified process | Manufactured in IATF 16949-certified facility; PPAP-capable with change control for automotive programs. |

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-20CPH06 | Same 60V/20A rating but planar Schottky; VF = 0.62V @ 10A/25°C; IR = 0.5mA @ 60V/25°C. | Higher conduction loss and leakage reduce efficiency in thermally constrained telecom modules. | Prefer SDT20A60VCT where >94% efficiency or <100µA leakage at 125°C is required. |
| ON Semiconductor MBR2060CT | Trench Schottky with identical TO220AB package; VF = 0.72V @ 10A/25°C; no AEC-Q101 qualification. | Lacks automotive change control and PPAP support; unsuitable for Tier-1 automotive BOMs. | Choose SDT20A60VCT for automotive programs requiring IATF 16949 traceability and AEC-Q101 documentation. |
Compared with VS-20CPH06 and MBR2060CT, SDT20A60VCT delivers superior thermal stability (50µA IR at 125°C vs. ≥200µA), lower VF (0.47V vs. ≥0.62V), and formal automotive qualification-making it optimal for high-reliability, high-efficiency, and temperature-critical deployments.

FAQ
Is SDT20A60VCT suitable for synchronous rectification?
No-SDT20A60VCT is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. It replaces traditional diodes in freewheeling or output rectification roles but requires no gate drive. Its soft switching and low VF make it ideal where synchronous FET control complexity or cost is prohibitive.
What is the thermal pad connection on the TO220AB package?
The metal tab (Pin 2) is the common cathode and must be electrically isolated from the heatsink unless the cathode node is at system ground potential. Diodes recommends using an insulating thermal pad (e.g., mica or polymer film) with thermal grease to maintain electrical isolation while achieving RθJC = 2°C/W.
Does SDT20A60VCT meet AEC-Q101 requirements?
Yes-SDT20A60VCT is manufactured in IATF 16949-certified facilities and qualifies per AEC-Q101 stress test requirements. While the datasheet notes "PPAP capable" and "change control for automotive," full AEC-Q101 test reports are available upon request via Diodes' automotive support team.
Can SDT20A60VCT replace MBR2060CT in existing designs?
Yes-SDT20A60VCT shares the same TO220AB footprint and pinout, offers lower VF (0.47V vs. 0.72V), and improved high-temperature leakage. No layout changes are needed; thermal performance improves due to lower power dissipation, allowing potential heatsink downsizing.
