Product details
Overview
SBG1640CT-T-F from Diodes Incorporated is a 16A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK package, rated for 40V peak repetitive reverse voltage and 0.55V forward voltage at 8.0A per element, designed for low-voltage, high-frequency DC-DC conversion and polarity protection in industrial power supplies.
For engineers reviewing the SBG1640CT-T-F datasheet, SBG1640CT-T-F pinout, SBG1640CT-T-F application, or SBG1640CT-T-F equivalent, key selection criteria include its 175A non-repetitive surge rating, 3.0°C/W junction-to-case thermal resistance, 275pF typical capacitance at 1MHz, and RoHS-compliant tin-plated terminals suitable for automated SMT assembly.
Technical Context
This dual-element Schottky rectifier integrates two independent anode terminals (Pins 1 & 3) sharing a common cathode (Pins 2 & 4), enabling synchronous rectification or dual-output configurations without external parallel diodes. Its guard ring die construction provides inherent transient protection against voltage spikes during switching transitions.
The device operates across –65°C to +125°C with derated current above 95°C case temperature, and exhibits stable reverse leakage (1.0mA @ 25°C, 50mA @ 125°C) under rated blocking voltage - critical for maintaining efficiency in thermally constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum peak reverse voltage each anode-cathode path withstands without breakdown |
| IO (TC = 95°C) | 16 A - Continuous average forward current per element with heatsink mounting at 95°C case temp |
| VFM @ IF = 8.0A | 0.55 V - Low conduction loss per element, reducing power dissipation in high-current paths |
| IFSM (8.3ms) | 175 A - Surge capability supports inrush current handling in SMPS startup and motor drive freewheeling |
| RθJC | 3.0 °C/W - Enables direct thermal coupling to PCB copper or heatsink for reliable 16A operation |
| CT @ 1MHz | 275 pF - Low junction capacitance minimizes switching losses and EMI in >100kHz converters |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent input terminal for first Schottky element; connects to high-side switch node |
| Pin 2 & Pin 4 | Common Cathode | Shared output node for both elements; soldered to power ground plane or output rail |
| Pin 3 | Anode 2 | Independent input terminal for second Schottky element; used for dual-output or phase-split designs |
Key Features
| Feature | Design Value |
|---|---|

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-16CTH04-M3/45 | Same 40V VRRM, 16A IO, but TO-220AC package with higher RθJC (4.0°C/W); no common-cathode pinout | Requires separate cathode traces and larger heatsink; unsuitable for space-constrained D²PAK layouts | Select only when through-hole assembly or legacy footprint compatibility is required |
| ON Semiconductor MBR1645CT | 45V VRRM, identical D²PAK package and pinout, but 0.62V VFM @ 8A and 4.5°C/W RθJC | Higher forward loss reduces efficiency in 12V-output designs; lower thermal performance limits max current at elevated ambient | Choose only if 45V blocking margin is mandatory and efficiency loss is acceptable |
Compared with VS-16CTH04-M3/45 and MBR1645CT, SBG1640CT-T-F delivers optimal balance of low conduction loss (0.55V), superior thermal resistance (3.0°C/W), and D²PAK-compatible dual-common-cathode layout - making it preferred for high-density, high-efficiency SMT power stages where thermal management and board area are critical.

FAQ
Is SBG1640CT-T-F suitable for automotive applications?
Yes - SBG1640CT-T-F operates from –65°C to +125°C, meets RoHS compliance, and has been validated in automotive DC-DC converters for infotainment and body control modules. Its 175A surge rating handles load dump events, and the D²PAK package supports reflow soldering per J-STD-020C Level 1 moisture sensitivity.
What is the recommended PCB layout for thermal performance?
Maximize copper area connected to Pins 2 & 4 (common cathode) using ≥2 oz copper and multiple thermal vias to inner ground planes. Keep anode traces (Pins 1 & 3) short and wide. A minimum 400 mm² exposed copper pad under the D²PAK body reduces RθJA by up to 15°C/W versus standard layout.
Does SBG1640CT-T-F require a heatsink for 16A operation?
No external heatsink is required if mounted on ≥400 mm² of 2 oz copper with ≥6 thermal vias to internal ground layers. At TC = 95°C, the 3.0°C/W RθJC allows full 16A current with ≤45°C temperature rise above ambient - achievable in well-designed 4-layer boards with forced air cooling.
Can SBG1640CT-T-F replace SBG1635CT or SBG1645CT in existing designs?
Yes - all SBG16xxCT variants share identical D²PAK package, pinout, and thermal characteristics. Substituting SBG1640CT-T-F for SBG1635CT increases blocking voltage from 35V to 40V; substituting for SBG1645CT reduces VRRM from 45V to 40V but improves VFM from 0.62V to 0.55V, enhancing efficiency in 12V-output systems.
