Product details
Overview
SDT20150GCT from Diodes Incorporated is a 20A dual-leg trench Schottky rectifier in TO220AB package, rated for 150V reverse voltage, with 0.82V max forward voltage at 10A/25°C and 8µA max reverse leakage at 150V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +175°C junction temperature.
For engineers reviewing the SDT20150GCT datasheet, SDT20150GCT pinout, SDT20150GCT application, or SDT20150GCT equivalent, key selection criteria include its low VF stability across temperature, soft-switching behavior, thermal resistance of 2°C/W (junction-to-case), and AEC-Q101 readiness for automotive power stages.
Technical Context
This dual-anode, common-cathode Schottky rectifier integrates two independent 10A legs sharing one 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 +125°C.
The device operates with no minority-carrier storage, eliminating reverse recovery charge (Qrr ≈ 0), making it suitable for high-frequency switching (>100 kHz) where di/dt-induced ringing and EMI must be minimized. Thermal performance is validated with aluminum fin heatsinks per JEDEC JESD51-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per leg; defines safe operation in 12–48V bus systems with 20% margin. |
| IO (per leg) | 10 A - Continuous average forward current per anode; supports 20A total dual-leg output in parallel-configured supplies. |
| VF max | 0.82 V @ 10A, 25°C - Directly reduces conduction loss by ~8.2W per leg vs. silicon diode (1.1V), improving efficiency in 12V→5V/3.3V buck converters. |
| IR max | 8 µA @ 150V, 25°C - Enables stable operation in high-impedance bias networks and low-power standby circuits without leakage-induced drift. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance with specified heatsink; allows 100W dissipation before reaching 175°C TJ when TC ≤ 75°C. |
| TJ range | −55 to +175 °C - Extended temperature capability supports under-hood automotive modules and industrial motor drives. |
Pinout & Package
TO220AB package with three terminals: Anode 1 (Pin 1), Anode 2 (Pin 2), Cathode (Pin 3). Mounting tab is electrically connected to Cathode (Pin 3) and serves as primary heat path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input node for first rectifier leg | Connects to transformer secondary or switch node in half-bridge LLC; isolated from Pin 2 for dual-phase operation. |
| Pin 2 (Anode 2) | Input node for second rectifier leg | Enables interleaved or dual-output configurations; electrically independent but thermally coupled to Pin 1 via shared die substrate. |
| Pin 3 (Cathode) | Common output node | Shared cathode connection reduces PCB trace inductance and improves current sharing; tab must be heatsinked and grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Super low forward voltage drop | 0.68V typ @ 10A/125°C - Maintains <1% efficiency loss in 12V→3.3V point-of-load converters at full load and elevated ambient. |
| Soft, fast switching capability | Qrr ≈ 0 - Eliminates reverse recovery spikes, reducing snubber losses and EMI filter size in 300–500kHz SMPS designs. |
| High-temperature leakage stability | IR = 0.4 µA @ 150V/125°C - Ensures minimal standby power loss in automotive infotainment systems operating at 105°C case temperature. |
| Lead-free & halogen-free construction | RoHS 3 compliant, Br+Cl <1500 ppm - Meets IPC-1752A material declaration requirements for Tier 1 automotive suppliers. |
Applications
| Automotive DC-DC Converters | Server VRMs |
|---|---|
Use Scenario: 48V–12V bidirectional buck-boost converter in mild hybrid vehicles. IC Role / Device Role / Timing Role: Output synchronous rectifier replacing MOSFETs in high-side position to reduce gate drive complexity and conduction loss.

IC Role / Device Role / Timing Role: Freewheel diode in multiphase buck converter with 1MHz+ switching frequency. Use Value: Zero Qrr eliminates reverse recovery noise, allowing tighter EMI compliance margins and smaller ceramic output capacitors. |
| Industrial AC-DC Adapters | Telecom Power Supplies |
Use Scenario: 100W universal-input (90–264VAC) adapter for PLC I/O modules. IC Role / Device Role / Timing Role: Secondary-side output rectifier in LLC resonant 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-20CPH06-M3 | 60V VRRM, 20A single-anode, VF = 0.52V @ 10A/25°C | Limited to ≤48V systems; lower VF but insufficient for 150V bus protection | Select only for low-voltage, ultra-high-efficiency designs where reverse voltage stress is <65V. |
| ON Semiconductor MBR20150CT | 150V VRRM, 20A dual-leg, VF = 0.92V @ 10A/25°C, IR = 100µA @ 150V/25°C | Higher VF increases conduction loss by ~1W/leg; 12.5× higher IR limits high-temp reliability | Acceptable for cost-sensitive industrial adapters where 125°C operation is not required. |
Compared with VS-20CPH06-M3 and MBR20150CT, SDT20150GCT uniquely balances 150V robustness, sub-0.85V VF across temperature, and µA-level leakage-making it optimal for automotive and high-reliability 48V+ power conversion where thermal stability and EMI control are critical.

FAQ
Is SDT20150GCT qualified to AEC-Q101?
Yes, SDT20150GCT is AEC-Q101 qualified per Diodes Incorporated's product definitions and manufactured in IATF 16949-certified facilities. Full PPAP documentation and change control are available upon request for automotive programs.
What is the maximum continuous case temperature for reliable operation?
The SDT20150GCT supports continuous operation up to +150°C case temperature when mounted on a 25mm × 44mm × 13.6mm aluminum heatsink, as verified by Figure 4 in DS43509 Rev. 3–2. Derating begins above this point per the published IO vs. TC curve.
Can SDT20150GCT replace standard silicon rectifiers in existing designs?
Yes-its pin-compatible TO220AB footprint and common-cathode configuration allow direct replacement of legacy 20A dual-diode packages like 20CPQ150, provided layout accommodates lower VF-induced thermal profile and reduced snubbing needs due to zero Qrr.
Does SDT20150GCT have a built-in thermal shutdown feature?
No, SDT20150GCT is a passive rectifier with no integrated thermal protection. System-level thermal management-via heatsinking, airflow, and current derating per Figure 4-is required to maintain TJ ≤ +175°C under all operating conditions.
