Product details
Overview
SBG1630CT-T from Diodes Incorporated is a 16A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK package, rated for 30V peak repetitive reverse voltage and 0.55V forward voltage at 8.0A per element, used in low-voltage DC-DC output stages and polarity protection circuits.
For engineers reviewing the SBG1630CT-T datasheet, SBG1630CT-T pinout, SBG1630CT-T application, or SBG1630CT-T 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 high-frequency inverters and free-wheeling diode roles.
Technical Context
This dual-element Schottky rectifier integrates two independent anode terminals (Pins 1 & 3) sharing a common cathode (Pins 2 & 4), enabling synchronous half-bridge or dual-output configurations. Its guard ring die construction provides transient overvoltage immunity without external clamping.
Designed for operation up to +125°C junction temperature, it delivers stable forward conduction with minimal self-heating under 16A average load at TC = 95°C, and exhibits low capacitive coupling (275pF) critical for EMI-sensitive switching power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum peak reverse voltage each anode-cathode path withstands without breakdown |
| IO (per element) | 16 A - Continuous average forward current per diode at TC = 95°C, defining heatsink sizing requirement |
| VFM @ 8.0A | 0.55 V - Low conduction loss per element, reducing power dissipation in high-current DC outputs |
| IFSM | 175 A - Peak surge current tolerance for 8.3ms half-sine, supporting inrush and fault transients |
| RθJC | 3.0 °C/W - Thermal resistance from junction to case, enabling direct heatsink mounting for thermal management |
| CT @ 1MHz | 275 pF - Total capacitance per element at 4V reverse bias, limiting high-frequency switching noise coupling |
Pinout & Package
Package: D²PAK (TO-263-4L), molded plastic case with UL 94V-0 flammability rating, 1.7g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first Schottky diode element; connects to high-side switch node in buck converter |
| Pin 2 & Pin 4 | Common Cathode | Shared output node for both diodes; soldered directly to PCB ground plane or heatsink for thermal conduction |
| Pin 3 | Anode 2 | Input terminal for second Schottky diode element; used for dual-rail or redundant output paths |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enables robust transient voltage suppression without external TVS, improving system-level surge immunity |
| Low forward voltage drop | 0.55V at 8A reduces conduction losses by >30% vs. standard silicon rectifiers in 5–12V output rails |
| 175A surge rating | Supports motor startup currents and capacitor charging surges without degradation in industrial power modules |
| Dual common-cathode configuration | Allows compact layout of two independent rectification paths sharing thermal mass and ground return |
Applications
| DC-DC Converter Output Stage | Polarity Protection Circuit |
|---|---|

IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode to reduce conduction loss and improve efficiency. Use Value: 0.55V VFM minimizes power loss at 16A load, directly increasing converter efficiency by 1.2–1.8% over comparable Si diodes. | Use Scenario: Reverse-voltage blocking in 24V industrial control inputs with hot-swap capability. IC Role / Device Role / Timing Role: Input protection diode preventing damage during incorrect cable insertion or field wiring errors. Use Value: 30V VRRM and 175A IFSM ensure survival against 24V system transients and accidental -48V misconnection events. |

Use Scenario: Low-loss freewheeling path in 100kHz+ resonant LLC inverters for LED drivers and AC adapters. IC Role / Device Role / Timing Role: Fast-recovery passive clamp element minimizing switching node ringing and EMI generation. Use Value: 275pF CT limits displacement current during dV/dt transitions, reducing gate drive stress on primary-side switches. | Use Scenario: Dual-output 12V rail in medical power supplies requiring fault-isolated backup paths. IC Role / Device Role / Timing Role: Independent anode terminals (Pins 1 & 3) enable separate input sourcing with shared cathode return. Use Value: Common-cathode topology allows single heatsink mounting while maintaining electrical isolation between input sources. |
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 | Same 30V VRRM, but TO-220AC package; RθJC = 2.5°C/W; higher 0.62V VFM @ 8A | Requires through-hole mounting and larger board area; better thermal performance but lower efficiency | Select when board space permits through-hole and heatsink interface is superior to D²PAK footprint |
| ON Semiconductor MBR1630CT | Identical D²PAK package and 30V rating; VFM = 0.57V @ 8A; IFSM = 150A (vs. 175A) | Slightly lower surge margin; same PCB layout compatibility and thermal interface | Choose when supply chain diversification is prioritized and 25A lower surge rating is acceptable |
Compared with VS-16CTH03-M3 and MBR1630CT, SBG1630CT-T offers the best balance of low VFM (0.55V), high surge (175A), and surface-mount D²PAK integration-critical for compact, high-efficiency 12–24V power systems where thermal and electrical performance must co-optimize.

FAQ
What is the maximum operating junction temperature for SBG1630CT-T?
The SBG1630CT-T has an operating junction temperature range of –65°C to +125°C. Its thermal design requires maintaining TJ ≤ +125°C under worst-case load and ambient conditions, supported by the 3.0°C/W RθJC value when mounted on an appropriate heatsink.
Is SBG1630CT-T lead-free and RoHS compliant?
Yes, SBG1630CT-T features a lead-free finish and is RoHS compliant per EU Directive Annex Note 7, with exemptions applied for glass and high-temperature solder. Terminal plating is tin, verified solderable per MIL-STD-202, Method 208.
How does the dual common-cathode configuration affect PCB layout?
The dual common-cathode structure (Pins 2 & 4 tied internally) allows both anodes (Pins 1 & 3) to share one large copper pour for cathode connection and thermal sinking. This simplifies layout by eliminating separate cathode traces and improves thermal uniformity across both elements.
Can SBG1630CT-T replace a single 16A Schottky in a single-output application?
Yes - only one anode (e.g., Pin 1) and the common cathode (Pins 2 & 4) need to be used; Pin 3 remains unconnected. The unused anode introduces negligible leakage or capacitance impact, preserving full 16A current rating and thermal performance in single-path designs.
