Product details
Overview
SDT30150GCT from Diodes Incorporated is a 150 V, 15 A per-leg trench Schottky rectifier in TO220AB package, featuring 0.88 V max forward voltage at 15 A and 8 µA max reverse leakage at 25°C. It delivers soft, fast switching with high-temperature stability and is qualified for automotive-grade thermal environments up to +175°C junction temperature. Used as a freewheel or blocking diode in DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT30150GCT datasheet, SDT30150GCT pinout, SDT30150GCT application, or SDT30150GCT equivalent, key selection criteria include its low VF at high current, stable IR across temperature, TO220AB thermal resistance (2°C/W with heatsink), and suitability for high-efficiency power conversion where conduction loss minimization is critical.
Technical Context
This dual-leg Schottky rectifier integrates two independent 150 V / 15 A diodes in a single TO220AB package, enabling shared thermal management and compact board layout. Its trench MOS structure enables lower VF than planar Schottky devices while maintaining low IR drift up to 125°C.
The device operates with no minority-carrier storage, eliminating reverse recovery charge (Qrr ≈ 0), making it ideal for high-frequency switching topologies. Thermal resistance of 2°C/W (junction-to-case) supports 30 A total device current when mounted on an 80 mm × 80 mm × 1.5 mm copper heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in 12–48 V DC-DC output stages. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg; supports 30 A total device rating with balanced load sharing. |
| VF max @ 15 A, 25°C | 0.88 V - Peak forward drop defining conduction loss; yields ~13.2 W dissipation per leg at full current. |
| IR max @ 150 V, 25°C | 8 µA - Reverse leakage limiting standby power loss in blocking applications; remains <10 µA at 125°C. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance with specified heatsink; enables precise thermal design for 175°C max TJ operation. |
| IFSM | 250 A - Non-repetitive surge rating for 8.3 ms half-sine; withstands inrush and fault transients in adapter inputs. |
Pinout & Package
TO220AB package with 3-terminal configuration: Anode 1, Cathode (common), Anode 2. The cathode tab is electrically connected to the metal mounting surface and serves as the common return path for both diode legs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first diode leg | Connects to switching node or input rail; isolated from Anode 2 and Cathode except through internal die. |
| Cathode (Tab) | Common output/return for both legs | Electrically tied to metal case; requires insulated mounting if referenced to non-ground potential. |
| Anode 2 (Lead 2) | Input terminal for second diode leg | Enables dual-channel rectification or interleaved operation without external parallel wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Super low forward voltage | 0.88 V max at 15 A/25°C reduces conduction loss by ≥15% vs. standard Schottky alternatives in 12–24 V outputs. |
| High-temperature leakage stability | IR ≤10 µA at 150 V/125°C ensures minimal standby power degradation in under-hood automotive modules. |
| Soft, fast switching | Zero Qrr and no reverse recovery tail enable clean turn-off in >300 kHz synchronous rectifiers and LLC resonant converters. |
| Automotive-capable construction | Manufactured in IATF 16949-certified facilities; supports PPAP documentation upon request for AEC-Q101-compliant designs. |

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-30CPH01-M3 | 100 V VRRM, 30 A total, VF = 0.72 V @ 15 A, RθJC = 1.5°C/W | Limited to ≤100 V systems; superior thermal performance but lower voltage margin | Select when system max reverse voltage ≤100 V and heatsink area is constrained. |
| ON Semiconductor MBR30H150CT | 150 V VRRM, 30 A total, VF = 0.92 V @ 15 A, IR = 100 µA @ 125°C | Higher leakage at elevated temperature; less suitable for hot ambient automotive use | Acceptable for commercial-industrial adapters where TJ < 105°C and leakage sensitivity is low. |
Compared with VS-30CPH01-M3 and MBR30H150CT, SDT30150GCT provides optimal balance of 150 V rating, low-temperature-stable leakage, and industry-standard TO220AB footprint-making it preferred for automotive and high-reliability 12–48 V DC-DC designs where voltage margin and thermal robustness are prioritized over marginal VF reduction.

FAQ
Is SDT30150GCT suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. However, its zero reverse recovery charge (Qrr ≈ 0) and soft switching behavior make it an effective replacement for active synchronous rectifiers in medium-frequency (<500 kHz) topologies where gate drive complexity must be avoided.
What is the maximum continuous case temperature for SDT30150GCT?
The maximum case temperature is not directly specified, but the device supports continuous operation up to +175°C junction temperature. With RθJC = 2°C/W and 30 A total current, sustained case temperatures above +125°C require active cooling or derating per Figure 4's derating curve.
Does SDT30150GCT have AEC-Q101 qualification?
The datasheet states it is manufactured in IATF 16949-certified facilities and supports PPAP for automotive applications, but formal AEC-Q101 test reports are not included in DS43508 Rev. 3–2. Customers requiring certified qualification should contact Diodes' automotive team for test documentation status.
Can SDT30150GCT replace a single 30 A Schottky in TO-247?
No-its 30 A rating is split across two 15 A legs. Replacing a monolithic 30 A TO-247 device would require verifying shared thermal path, current balancing, and PCB layout compatibility. The TO220AB footprint and dual-anode topology differ fundamentally from single-die TO-247 configurations.
