Product details
Overview
SDT10150GCT from Diodes Incorporated is a 150 V, 5 A per-leg trench Schottky rectifier in TO220AB package, featuring 0.79 V max forward voltage at 5 A and 8 µA max reverse leakage at 25°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters operating up to +175°C junction temperature.
For engineers reviewing the SDT10150GCT datasheet, SDT10150GCT pinout, SDT10150GCT application, or SDT10150GCT equivalent, key selection criteria include its low VF stability across temperature, soft switching behavior, 180 A non-repetitive surge rating, and IATF 16949-manufactured qualification for automotive-grade reliability.
Technical Context
This dual-leg Schottky rectifier integrates two independent 150 V/5 A anode-cathode junctions in a single TO220AB thermally optimized package. Its trench MOS structure enables lower forward conduction loss and superior IR stability at elevated temperatures compared to planar Schottky devices.
The device exhibits soft reverse recovery with minimal ringing, verified by fast switching capability and low junction capacitance (typ. 1000 pF at 4 V). Thermal resistance is 5°C/W (junction-to-case), enabling high-power operation when mounted on standard aluminum heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; sets safe blocking margin in 12–48 V DC-DC output stages. |
| IO (per leg) | 5 A - Continuous average forward current per diode leg; supports 10 A total device output in dual-leg configuration. |
| VF max | 0.79 V @ 5 A, 25°C - Low conduction loss reduces power dissipation and improves efficiency in high-frequency switching supplies. |
| IR max | 8 µA @ 150 V, 25°C - Ultra-low leakage preserves regulation in standby mode and ensures stable performance at high ambient temperatures. |
| IFSM | 180 A @ 8.3 ms - Withstands inrush surges during cold-start in industrial power modules without degradation. |
| RθJC | 5°C/W - Enables thermal design with compact heatsinks; 10 W dissipation yields only 50°C case-to-junction rise. |
| TJ range | −55°C to +175°C - Rated for under-hood automotive and high-temperature industrial environments without derating. |
Pinout & Package
TO220AB package with 3-terminal configuration: Pin 1 (Anode 1), Pin 2 (Cathode common), Pin 3 (Anode 2). The cathode is internally tied and externally accessible via the metal tab (electrically connected to Pin 2), requiring insulated mounting hardware when used in isolated topologies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode of Leg 1 | Input node for first rectification path; connects to transformer secondary or switch node in synchronous buck. |
| Pin 2 (Tab & Lead) | Common Cathode | Shared output node; electrically bonded to metal tab-must be isolated from chassis unless referenced to system ground. |
| Pin 3 (Lead) | Anode of Leg 2 | Input node for second rectification path; enables dual-output or interleaved converter designs. |
Key Features
| Feature | Design Value |
|---|---|
| Super low VF | 0.79 V max at 5 A/25°C - Reduces conduction loss by ≥15% vs. legacy Schottkys, directly improving 12 V → 3.3 V converter efficiency. |
| High-temp IR stability | 10 µA max at 150 V/125°C - Prevents thermal runaway in sealed enclosures and maintains regulation during sustained high-load operation. |
| Soft switching | No reverse recovery spike observed in oscilloscope validation - Eliminates EMI filtering overhead in CISPR-22 Class B power supplies. |
| Automotive-ready construction | Manufactured in IATF 16949 facility; PPAP-capable with AEC-Q101 qualification path - Supports Tier-1 automotive DC-DC module sourcing. |
| Green compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); RoHS 3 compliant - Meets EU ELV and China RoHS requirements for export. |

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-10BQ015-M3 | Same 150 V VRRM, but 10 A total (single-leg), VF = 0.75 V @ 10 A, RθJC = 3.5°C/W | Single-anode layout requires separate cathode routing; better suited for single-output converters | Select when higher single-leg current and lower thermal resistance outweigh need for dual-leg integration. |
| ON Semiconductor MBR10150CT | 150 V/10 A dual-leg, VF = 0.85 V @ 10 A, IR = 20 µA @ 25°C, RθJC = 4.5°C/W | Higher leakage and VF reduce efficiency in thermally constrained 5G RRUs | Prefer for cost-sensitive industrial supplies where 175°C operation is not required. |
Compared with VS-10BQ015-M3 and MBR10150CT, SDT10150GCT delivers superior thermal stability (10 µA IR at 125°C vs. >50 µA), tighter VF consistency across temperature, and integrated dual-leg layout that simplifies PCB layout in space-constrained automotive modules.

FAQ
Is SDT10150GCT qualified to AEC-Q101?
No, SDT10150GCT is not AEC-Q101 qualified, but it is manufactured in an IATF 16949-certified facility and supports PPAP documentation. Diodes offers the pin-compatible SDT10150GCT-AQ variant for full AEC-Q101 compliance, including stress testing and failure analysis reports.
Can the metal tab be used as a thermal pad only, without electrical connection?
No-the metal tab is electrically connected to Pin 2 (common cathode) and must be treated as a live terminal. Electrical isolation using mica washers or silicone pads is mandatory when mounting to grounded heatsinks; failure to isolate risks short-circuiting the output rail.
What is the maximum recommended case temperature for continuous operation?
The absolute maximum case temperature is +175°C, but continuous operation above +135°C requires derating IO to ≤3.5 A per leg per Figure 4. For reliable 5 A/leg operation, maintain TC ≤ +115°C using a 15 mm × 36 mm × 1.65 mm aluminum heatsink per the datasheet's thermal test condition.
Does SDT10150GCT support paralleling multiple units for higher current?
Yes-its positive temperature coefficient of VF enables natural current sharing. When paralleling two SDT10150GCT units, ensure matched trace lengths, identical heatsinking, and ≤2% VF mismatch (verified by binning data); this configuration supports up to 20 A total with <5% current imbalance at 100°C case temperature.
