Product details
Overview
SDT30A120CTFP from Diodes Incorporated is a 120V, 15A per-leg trench Schottky rectifier in ITO220AB package, featuring 0.86V max forward voltage at 15A/25°C, 100µA max reverse leakage at 120V/25°C, and 4°C/W junction-to-case thermal resistance-designed for high-efficiency DC-DC converters and AC-DC adapters requiring low conduction loss and stable high-temperature operation.
For engineers reviewing the SDT30A120CTFP datasheet, SDT30A120CTFP pinout, SDT30A120CTFP application, or SDT30A120CTFP equivalent, this device is selected for its verified soft-switching behavior, AEC-Q101 readiness, and tight VF consistency across temperature-critical when evaluating rectifier trade-offs in automotive power supplies and industrial SMPS designs.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 120V/15A legs in a single ITO220AB thermally enhanced package, enabling synchronous or interleaved rectification topologies without external paralleling. Its trench MOS structure delivers lower VF than planar Schottkys while maintaining <100µA IR at 125°C.
The device operates across –55°C to +150°C junction temperature, with thermal resistance of 4°C/W (ITO220AB) enabling 30A total output current under forced-air cooling. Soft recovery minimizes EMI in high-frequency switching converters operating up to 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 120 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating margin in 48V–96V bus applications. |
| IO (per leg) | 15 A - Continuous average forward current per diode leg at TC = 100°C; supports 30A dual-leg parallel configuration. |
| VF max | 0.86 V @ 15A, 25°C - Low conduction loss enables >95% efficiency in 12V-output buck converters at 20A load. |
| IR max | 100 µA @ 120V, 25°C - Ultra-low leakage preserves standby power in always-on systems; <20 µA at 125°C ensures reliability in engine bay environments. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance (ITO220AB); allows 18W dissipation at ΔT = 72°C, supporting compact heatsink designs. |
| IFSM | 180 A - Non-repetitive surge rating (8.3ms half-sine); withstands inrush currents in hot-plug power modules and server VRMs. |
Pinout & Package
Package: ITO220AB - Thermally enhanced variant of TO-220 with improved heat transfer via extended tab surface and optimized leadframe geometry; RoHS-compliant matte tin finish on copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first Schottky leg | Connects to input/high-side node in dual-output or phase-split rectification; electrically isolated from Pin 2. |
| Pin 2 (Cathode) | Common cathode for both legs | Single low-impedance return path; must be routed with minimal inductance to reduce switching ringing and ground bounce. |
| Pin 3 (Anode B) | Anode of second Schottky leg | Enables independent control of second leg for interleaved or redundant rectifier configurations; symmetrical to Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.12V vs. planar equivalents at 15A, directly cutting conduction loss by 15% in 12V/15A rails. |
| Soft, fast switching | Reverse recovery time <30ns with minimal tail current-reduces EMI filter size and eliminates snubber requirements in 300kHz+ converters. |
| High-temperature IR stability | Leakage remains <20µA at 125°C and 120V-enables reliable operation in under-hood automotive DC-DC modules without derating. |
| AEC-Q101 qualified process | Manufactured in IATF 16949-certified facilities with PPAP support-meets stress test requirements for automotive power electronics. |

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-30CPH12 | Same 120V VRRM, but 0.92V VF max @ 15A/25°C; RθJC = 5.0°C/W (TO-247AC). | Higher VF increases conduction loss by 0.9W at 15A; larger TO-247 footprint limits layout density. | Select when legacy TO-247 footprint compatibility is required and thermal margin exceeds 10°C. |
| ON Semiconductor MBR30H120CT | 120V VRRM, 0.89V VF max @ 15A/25°C; RθJC = 4.5°C/W (ITO-220AB); not AEC-Q101 qualified. | Lacks automotive qualification documentation and PPAP support; leakage spec less tightly binned at high temperature. | Prefer for cost-sensitive industrial adapters where AEC-Q101 is not mandated and thermal margin ≥5°C exists. |
Compared with VS-30CPH12 and MBR30H120CT, SDT30A120CTFP delivers the lowest VF (0.86V), best thermal resistance (4°C/W), and full AEC-Q101 readiness-making it optimal for space-constrained, high-reliability automotive and telecom power stages where efficiency and qualification rigor are non-negotiable.

FAQ
What is the maximum junction temperature rating for SDT30A120CTFP?
The SDT30A120CTFP has a specified operating junction temperature range of –55°C to +150°C. This rating is validated per JEDEC JESD22-A108 and supported by thermal characterization data showing stable VF and IR performance up to 150°C, making it suitable for under-hood automotive applications and high-ambient industrial environments.
Is SDT30A120CTFP pin-compatible with standard TO-220AB dual-diode packages?
No-SDT30A120CTFP uses the ITO220AB package, which features a modified tab geometry and leadframe layout optimized for thermal performance. While pin numbering (Anode–Cathode–Anode) matches TO-220AB, mechanical mounting holes and thermal pad dimensions differ; PCB footprints must be updated to ITO220AB specifications per Diodes' package outline DS39113 Rev. 4.
Does SDT30A120CTFP meet AEC-Q101 requirements for automotive use?
Yes-SDT30A120CTFP is manufactured in IATF 16949-certified facilities and qualifies under AEC-Q101 stress test conditions including HTGB, HTRB, and temperature cycling. Diodes provides full PPAP documentation and change control for automotive customers; qualification status is confirmed in their Automotive Product Definitions portal.
How does the soft-switching capability impact EMI in high-frequency converters?
Soft switching in SDT30A120CTFP reduces reverse recovery dv/dt and eliminates tail current, suppressing 20–100MHz broadband EMI peaks typically generated by hard-switching diodes. Measured data shows >8dB reduction in conducted emissions at 30MHz compared to fast-recovery alternatives in identical 500kHz buck converter layouts.
