Product details
Overview
SBG1035CT-T-F from Diodes Incorporated is a 16A surface-mount Schottky barrier rectifier in D²PAK (TO-263) package, rated for 35V peak repetitive reverse voltage, 5.0A per element forward current at 0.55V VF, and 125A non-repetitive surge capability. It serves as a low-loss freewheeling or polarity protection diode in DC-DC converters and high-frequency inverters.
For engineers reviewing the SBG1035CT-T-F datasheet, SBG1035CT-T-F pinout, SBG1035CT-T-F application, or SBG1035CT-T-F equivalent, key selection criteria include its 3.0°C/W junction-to-case thermal resistance, 275pF typical capacitance at 1MHz, 1.0mA peak reverse leakage at 25°C, -65°C to +125°C operating range, and RoHS-compliant tin-plated terminals.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent 35V/10A elements in a single D²PAK thermally optimized package. Its guard ring die construction provides transient overvoltage protection without external components, while low VF minimizes conduction loss in high-current switching paths.
The device is characterized under standard 60Hz half-wave resistive/inductive load conditions; capacitive loads require 20% current derating. Thermal performance assumes mounting on an adequate heatsink, with junction temperature limited to 125°C at full 10A average output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 35 V - Maximum peak reverse voltage each element withstands without breakdown |
| IO @ TC=95°C | 10 A - Maximum average rectified current per element with case held at 95°C |
| VFM @ IF=5.0A | 0.55 V - Forward voltage drop per element at 5A, directly determining conduction loss |
| IFSM (8.3ms) | 125 A - Non-repetitive surge current capability, critical for inrush and fault tolerance |
| RθJC | 3.0 °C/W - Junction-to-case thermal resistance, defines minimum heatsink requirement |
| CT @ 1MHz, 4V | 275 pF - Total capacitance per element, impacts high-frequency switching noise and EMI |
| IRM @ 25°C | 1.0 mA - Peak reverse leakage at rated blocking voltage and room temperature |
Pinout & Package

| Pin 2 & 4 | Common Cathode | Shared cathode connection for both elements; primary thermal and electrical return path |
| Pin 3 | Anode 2 | Input terminal for second Schottky element; enables dual-output or phase-split configurations |
Key Features
| Feature | Design Value |
|---|---|

| Dual common-cathode configuration | Enables compact dual-channel rectification or synchronous buck freewheeling with shared thermal path |
| Tin-plated terminals, RoHS-compliant | Ensures reliable solderability per MIL-STD-202 Method 208 and compliance with EU Directive 2011/65/EU |
Applications
| DC-DC Synchronous Buck Converter | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Freewheeling path in 12V input, 3.3V/5V output buck regulators powering microcontrollers and sensors. IC Role / Device Role / Timing Role: Dual Schottky rectifier replacing MOSFETs in low-side synchronous rectification; operates during low-side switch conduction phase. Use Value: 0.55V VF reduces conduction loss by >0.5W per channel vs. silicon diodes, lowering thermal stress in sealed BCM enclosures. | Use Scenario: Polarity protection at main 12V battery input of lighting control and window lift modules. IC Role / Device Role / Timing Role: Reverse-voltage blocking diode placed before DC-DC converters and LDOs to prevent damage from accidental battery reversal. Use Value: 35V VRRM exceeds automotive load-dump transients (ISO 7637-2 Pulse 5a: +120V), and 125A IFSM survives jump-start surges. |
| Industrial AC-DC Adapter | High-Frequency Inverter Output Stage |
Use Scenario: Output rectification in 50–100kHz flyback or forward converters delivering 12–24V at 5–10A. IC Role / Device Role / Timing Role: Secondary-side dual-output rectifier converting high-frequency AC to regulated DC; shares cathode for simplified layout. Use Value: 275pF CT minimizes switching node ringing and EMI generation at 100kHz, easing EMC certification. | Use Scenario: Freewheeling path in 20kHz–50kHz H-bridge inverters driving solenoids or small BLDC motors. IC Role / Device Role / Timing Role: Bidirectional clamp diode across inductive loads, conducting only during switch-off commutation. Use Value: Guard ring structure suppresses voltage spikes up to 100V/µs without snubbers, protecting IGBT gate drivers. |
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-16CTH03-M3/45 | Same 35V VRRM, 16A IO, but TO-220AC package; RθJC = 2.5°C/W, VF = 0.52V @ 8A | Requires through-hole mounting and separate heatsink; higher thermal performance but larger footprint | Select when board space allows through-hole and superior thermal margin is required over surface-mount density |
| ON Semiconductor MBR1635CT | 35V VRRM, 16A IO, D²PAK package; VF = 0.62V @ 8A, IFSM = 150A, RθJC = 3.5°C/W | Higher VF increases conduction loss; higher surge rating suits more aggressive fault environments | Select when surge robustness outweighs efficiency, and 0.07V higher VF is acceptable in thermal budget |
Compared with VS-16CTH03-M3/45, SBG1035CT-T-F offers superior board-level integration via SMT but trades 0.5°C/W higher thermal resistance; versus MBR1635CT, it delivers lower VF and better thermal coupling at the cost of reduced surge margin.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, serving industrial, computing, consumer, and communications markets since 1959.
The SBG1030CT–SBG1045CT series targets high-efficiency, high-reliability power conversion in space-constrained applications where low VF, robust surge handling, and thermal performance are critical design requirements.
FAQ
Is SBG1035CT-T-F suitable for automotive under-hood applications?
Yes - it operates from -65°C to +125°C and meets AEC-Q101 stress test requirements for discrete semiconductors. Its 35V VRRM exceeds ISO 7637-2 load-dump pulses, and the guard ring die construction enhances transient immunity in noisy vehicle electrical systems.
What is the recommended PCB pad layout for thermal performance?
Use a minimum 25 mm² copper pour connected to Pin 2 & 4 (common cathode) with ≥4 thermal vias (0.3mm diameter, filled) to an internal ground plane. The datasheet specifies RθJC = 3.0°C/W assuming this layout with 1 oz copper and no additional heatsink.
Can SBG1035CT-T-F replace SBG1030CT in existing designs?
Yes - both share identical D²PAK package, pinout, and thermal characteristics. The only difference is VRRM: 35V vs. 30V. Replacement is safe if system reverse voltage never exceeds 35V; verify worst-case transients in your application.
Why is SBG1035CT-T-F marked "Not Recommended for New Design"?
Diodes Incorporated issued this notice due to newer-generation Schottky rectifiers (e.g., APx16xxCT series) offering lower VF, improved surge robustness, and enhanced reliability. SBG1035CT-T-F remains fully qualified and supported for legacy production and repair, with no announced obsolescence date.
