Product details
Overview
SDT30150GCTSP from Diodes Incorporated is a 150V, 15A per-leg trench Schottky rectifier in ITO-220AB (Type WX2) package, featuring 0.88V max forward voltage at 15A/25°C, 8µA max reverse leakage at 150V/25°C, and thermal resistance of 6°C/W (junction-to-case). It serves as a high-efficiency freewheel or blocking diode in automotive-grade DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT30150GCTSP datasheet, SDT30150GCTSP pinout, SDT30150GCTSP application, or SDT30150GCTSP equivalent, key selection criteria include high-temperature reverse leakage stability (≤10µA at 150V/125°C), soft-switching behavior for EMI reduction, and IATF 16949-manufactured qualification for automotive power systems.
Technical Context
This dual-leg Schottky rectifier integrates two independent 150V/15A junctions in a single ITO-220AB (Type WX2) thermally optimized package. Its trench MOS structure enables low VF and minimal stored charge, supporting soft recovery with <100ns reverse recovery time (typical).
Designed for high-reliability power conversion, it operates across –55°C to +175°C junction temperature range and sustains 250A non-repetitive surge current (8.3ms half-sine). The matte tin–plated copper leadframe ensures MIL-STD-202-compliant solderability and robust thermal interface to heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC-DC flyback or buck-boost topologies. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg; supports 30A total device rating with parallel internal configuration. |
| VF max | 0.88 V @ 15A, 25°C - Low conduction loss enabling >95% efficiency in 12V–48V input DC-DC stages. |
| IR max | 8 µA @ 150V, 25°C - Ultra-low leakage preserves standby power budget in always-on automotive modules. |
| RθJC | 6 °C/W - Thermal resistance with 200mm×200mm×10mm heatsink; enables 15A operation up to +125°C case temperature. |
| TJ range | –55°C to +175°C - Extended junction temperature capability meets AEC-Q101 stress requirements for under-hood applications. |
Pinout & Package
Package: ITO-220AB (Type WX2), surface-mount compatible through-hole variant with isolated tab, UL 94V-0 molded plastic body, and matte tin–plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first Schottky junction | Connects to switching node in synchronous rectification or freewheel path of buck converter. |
| Cathode Common (Lead 2) | Shared cathode connection for both legs | Provides low-inductance return path; electrically tied to metal tab for thermal and electrical grounding. |
| Anode 2 (Lead 3) | Input terminal for second Schottky junction | Enables dual-channel operation-e.g., independent phase legs in interleaved PFC or dual-output DC-DC. |
Key Features
| Feature | Design Value |
|---|---|
| Super low forward voltage drop | 0.71V typ @ 15A/25°C - Reduces conduction loss by ≥25% vs. planar Schottky alternatives at same rating. |
| High-temperature leakage stability | 10µA max @ 150V/125°C - Maintains <0.1W standby dissipation in hot ambient environments (e.g., engine bay). |
| Soft, fast switching | No minority-carrier storage; negligible reverse recovery charge - Eliminates snubber circuits in 100–500kHz SMPS designs. |
| AEC-Q101 qualified manufacturing | IATF 16949-certified production with PPAP support - Meets change control and traceability requirements for automotive Tier-1 BOMs. |
Applications
| Automotive DC-DC Converters | Industrial AC-DC Adapters |
|---|---|
Use Scenario: 12V-to-5V/3.3V point-of-load conversion in ADAS camera modules and infotainment ECUs. IC Role / Device Role / Timing Role: Freewheel diode in synchronous buck regulator; handles 15A peak inductive current during low-side switch off-time. Use Value: 0.88V VF minimizes heat generation in confined enclosures; 175°C TJ rating avoids derating at +105°C ambient. |
Use Scenario: Secondary-side rectification in universal-input 100W laptop adapters with active clamp flyback topology. IC Role / Device Role / Timing Role: Output rectifier replacing Si diodes; conducts continuous 15A DC output with <100ns turn-off. Use Value: Soft recovery eliminates 30–50MHz ringing, reducing EMI filter component count and board space. |
| Server PSU ORing Circuits | Renewable Energy Inverters |
Use Scenario: Hot-swap ORing diode in redundant 12V server backplanes with 20A aggregate current. IC Role / Device Role / Timing Role: Blocking diode preventing reverse current flow between paralleled PSUs during fault conditions. Use Value: Dual-leg layout allows 30A total current sharing; 6°C/W RθJC enables passive cooling without forced air. |
Use Scenario: Freewheel path in bidirectional DC-link chopper stage of solar microinverters. IC Role / Device Role / Timing Role: Anti-parallel diode conducting reactive current during zero-crossing intervals in 16kHz PWM switching. Use Value: Stable 8µA IR at 25°C and 10µA at 125°C ensures predictable losses across -40°C to +85°C outdoor operating range. |
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-30CPH015-M3 | Same 150V/15A rating but TO-247AC package; RθJC = 2.5°C/W; VF = 0.82V @ 15A/25°C. | Better thermal performance but larger footprint; requires screw-mount heatsink vs. clip-on for ITO-220AB. | Select when junction temperature must stay <110°C under full load without airflow. |
| ON Semiconductor MBR30150CT | TO-220AB package; VF = 0.92V @ 15A/25°C; IR = 15µA @ 150V/25°C; no AEC-Q101 qualification. | Limited to commercial/industrial use; higher leakage increases standby loss in battery-backed systems. | Choose only for cost-sensitive non-automotive designs where 175°C TJ rating is not required. |
Compared with VS-30CPH015-M3 and MBR30150CT, SDT30150GCTSP delivers optimal balance of automotive qualification, thermal interface simplicity (clip-on heatsink), and leakage-limited efficiency in high-ambient environments-making it preferred for space-constrained, thermally aggressive applications.

FAQ
What is the maximum junction temperature and how is it validated?
The SDT30150GCTSP is rated for –55°C to +175°C junction temperature, verified per AEC-Q101 stress test conditions including high-temperature reverse bias (HTRB) and temperature cycling. Its trench Schottky architecture inherently limits thermal runaway risk, and the 6°C/W RθJC value assumes a 200mm × 200mm × 10mm copper heatsink in free-air conditions.
Is SDT30150GCTSP pin-compatible with SDT30150GCT?
No-SDT30150GCT uses TO-220AB (Generic) with different mechanical dimensions and thermal pad layout, while SDT30150GCTSP uses ITO-220AB (Type WX2) with enhanced thermal isolation and tighter dimensional tolerances. PCB footprints, heatsink mounting, and thermal interface design are not interchangeable.
Does this part support PPAP documentation for automotive programs?
Yes-Diodes Incorporated provides full PPAP Level 3 documentation (including PSW, DFMEA, PFMEA, control plans, and measurement system analysis) for SDT30150GCTSP upon request, as it is manufactured in IATF 16949-certified facilities and qualified to AEC-Q101 standards.
How does its soft-switching behavior reduce EMI in high-frequency converters?
Unlike conventional PN-junction diodes, SDT30150GCTSP exhibits near-zero reverse recovery charge (Qrr ≈ 0 nC) due to majority-carrier conduction. This eliminates high di/dt-induced voltage spikes during turn-off, suppressing 30–100MHz common-mode noise that would otherwise require additional ferrite beads or Y-capacitors in EMI filters.
