Product details
Overview
SDT30100GCT from Diodes Incorporated is a 30A dual-leg Trench Schottky rectifier in TO220AB package, rated for 100V peak reverse voltage per leg, with 0.77V max forward voltage at 15A/25°C and 30µA max reverse leakage at 100V/25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters where low conduction loss and thermal stability are critical.
For engineers reviewing the SDT30100GCT datasheet, SDT30100GCT pinout, SDT30100GCT application, or SDT30100GCT equivalent, key selection criteria include per-leg current rating (15A), thermal resistance (2°C/W junction-to-case), soft switching behavior, high-temperature leakage performance (12µA at 125°C), and automotive-grade manufacturing qualification under IATF 16949.
Technical Context
This dual-anode, single-cathode Schottky rectifier integrates two independent 15A legs sharing a common cathode terminal, enabling synchronous or interleaved rectification topologies. Its Trench MOS structure delivers lower VF than planar Schottkys while maintaining stable IR up to +150°C junction temperature.
Designed for high-frequency switching power supplies, it exhibits soft reverse recovery (no stored charge) and low junction capacitance (≈1000pF at 0V), minimizing EMI and switching losses. Thermal design relies on direct case-to-heatsink mounting, with RθJC = 2°C/W specified for TO220AB using a 50mm×50mm×23mm aluminum heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM (Per Leg) | 100 V - Maximum non-repetitive reverse blocking voltage each anode can sustain without breakdown. |
| IO (Per Leg) | 15 A - Continuous average forward current per anode at TA = +25°C with adequate heatsinking. |
| VF Max @ 15A/25°C | 0.77 V - Peak forward voltage drop per leg, directly determining conduction loss (11.55W max per leg at 15A). |
| IR Max @ 100V/25°C | 30 µA - Maximum reverse leakage per leg, critical for standby power budgeting in energy-efficient adapters. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance, defining minimum heatsink requirement for safe 30A total device operation. |
| IFSM | 250 A - Non-repetitive surge current capability (8.3ms half-sine), supporting inrush and transient overload tolerance. |
| TJ Operating Range | –55°C to +150°C - Full industrial and automotive ambient compatibility without derating below +125°C. |
Pinout & Package
Package: TO220AB (Generic), molded plastic, UL 94V-0 rated, matte tin-plated copper leadframe, 1.85g typical weight. Mounting tab is electrically connected to cathode (Pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode for first rectifier leg | Accepts AC or switched input; isolated from Anode 2 for dual-channel operation. |
| Pin 2 (Anode 2) | Input anode for second rectifier leg | Enables dual-phase or parallel rectification; electrically independent of Pin 1. |
| Pin 3 (Cathode) | Common output cathode | Shared return path; tab-connected for low-inductance, high-current DC output routing. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.77V max at 15A/25°C reduces conduction loss by ≥15% vs. comparable 100V Schottkys. |
| High-temperature leakage stability | 12µA IR at 100V/125°C enables reliable operation in sealed, thermally constrained enclosures. |
| Soft, fast switching | No minority-carrier storage ensures zero reverse recovery time and minimal switching noise in >100kHz designs. |
| AEC-Q101 readiness | Manufactured in IATF 16949-certified facilities with PPAP capability-supports automotive qualification path. |
| Green compliance | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb), RoHS 3 compliant, lead-free finish. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-leg Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V30100CI | Same 100V/30A rating but VF = 0.82V @ 15A/25°C; RθJC = 2.5°C/W; TO220AB package. | Higher conduction loss (+0.05V) increases thermal load in compact enclosures above 60°C ambient. | Select when legacy Vishay footprint compatibility is required and 50mV VF penalty is acceptable. |
| ON Semiconductor MBR30100CT | VF = 0.79V @ 15A/25°C; IR = 50µA @ 100V/25°C; RθJC = 2.2°C/W; TO220AB package. | 20µA higher room-temp leakage impacts light-load efficiency in ENERGY STAR-compliant adapters. | Prefer for cost-sensitive industrial designs where leakage <30µA is not mandated. |
Compared with V30100CI and MBR30100CT, SDT30100GCT offers the lowest VF (0.77V) and tightest IR spec (30µA), making it optimal for thermally constrained, high-efficiency DC-DC and automotive applications where both conduction loss and standby power must be minimized.

FAQ
What is the maximum junction temperature and how is it enforced?
The SDT30100GCT has a rated TJ range of –55°C to +150°C. Operation beyond +150°C risks irreversible parametric shift and bond-wire failure. Thermal design must ensure dPD/dTJ < 1/RθJA, with RθJC = 2°C/W measured using a 50mm×50mm×23mm Al heatsink. Derating curves in Figure 5 define safe IO vs. TC limits.
Is SDT30100GCT qualified to AEC-Q101?
SDT30100GCT is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 in standard form, Diodes offers AEC-Q101 qualification upon request with controlled change management-contact your local Diodes representative for automotive-specific release documentation.
How does the dual-leg configuration affect PCB layout?
The dual-anode (Pins 1 & 2) / common-cathode (Pin 3) layout requires symmetrical copper pours for both anode traces to balance current sharing. The metal tab (Pin 3) must be soldered to a large thermal pad tied to internal ground/power planes. Keep anode-to-anode spacing ≥2.5mm to prevent creepage in 100V applications.
Can SDT30100GCT replace older 20A Schottky rectifiers like SB20100CT?
Yes-SDT30100GCT provides 50% higher total current (30A vs. 20A), lower VF (0.77V vs. ~0.85V), and improved high-temperature leakage (12µA vs. ~50µA at 125°C). Layout compatibility is maintained via identical TO220AB footprint and pinout, enabling drop-in upgrade in thermally limited designs.
