Product details
Overview
SBG1635CT-T-F from Diodes Incorporated is a 16A dual common-cathode surface-mount Schottky barrier rectifier in D²PAK package, rated for 35V peak repetitive reverse voltage and 0.55V forward voltage at 8.0A per element, used in low-voltage DC-DC output rectification and polarity protection circuits.
For engineers reviewing the SBG1635CT-T-F datasheet, SBG1635CT-T-F pinout, SBG1635CT-T-F application, or SBG1635CT-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 sharing a common cathode, enabling synchronous rectification or dual-output configurations without external parallel diodes. Its guard ring die construction provides inherent transient overvoltage protection during inductive load switching.
Designed for high-frequency operation up to several hundred kHz, it avoids reverse recovery losses typical of PN-junction rectifiers. The D²PAK package supports direct heatsink mounting with verified 3.0°C/W thermal resistance, enabling sustained 16A average current at TC = 95°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage | 35 V - Maximum DC or peak AC reverse bias before breakdown; defines safe operating range in 24V/32V bus systems. |
| Average Rectified Output Current | 16 A @ TC = 95°C - Continuous DC current capability per element when case temperature is maintained at 95°C via heatsinking. |
| Forward Voltage | 0.55 V @ IF = 8.0A - Low conduction loss per element, reducing power dissipation by ~4.4W vs. 0.8V Si diode at same current. |
| Non-Repetitive Peak Surge Current | 175 A (8.3ms half-sine) - Withstands brief inrush or fault currents without failure, critical for motor drive freewheeling. |
| Junction-to-Case Thermal Resistance | 3.0 °C/W - Enables predictable thermal design when mounted on heatsink; ΔTJC = 48°C at full 16A load. |
| Total Capacitance | 275 pF @ 1MHz, 4V reverse - Limits high-frequency noise coupling and EMI in switching regulator outputs. |
Pinout & Package
Package: D²PAK (TO-263AB), molded plastic case with UL 94V-0 flammability rating, 1.7g mass, moisture sensitivity level 1, tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input terminal for first rectifying element | Accepts positive input from source; connects to transformer secondary or switch node in synchronous buck. |
| Pin 2 & 4 (Cathode) | Common output node for both elements | Shared return path; must be routed with low-inductance copper to minimize voltage spikes during fast switching. |
| Pin 3 (Anode 2) | Input terminal for second rectifying element | Enables dual-output or interleaved topology; electrically isolated from Pin 1 except through shared cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Provides intrinsic transient voltage suppression without external TVS, improving system-level surge immunity per IEC 61000-4-5. |
| Low forward voltage drop | 0.55V at 8A reduces conduction loss by >30% versus comparable Si rectifiers, directly improving efficiency in 12–24V DC-DC converters. |
| High surge capability | 175A peak surge rating supports reliable operation during motor startup, capacitor charging, or short-circuit events in industrial power supplies. |
| Dual common-cathode configuration | Eliminates need for external parallel diodes in dual-rail outputs, saving PCB area and reducing parasitic inductance in high-current paths. |
Applications
| Server VRM Output Rectification | Industrial PLC Power Input Protection |
|---|---|
Use Scenario: Rectifying 12V output from multiphase buck converter in server voltage regulator module. IC Role / Device Role / Timing Role: Primary output rectifier replacing MOSFET synchronous switches where gate drive complexity is undesirable. Use Value: 0.55V VF minimizes conduction loss at 10–16A load, maintaining >92% efficiency while simplifying thermal layout via D²PAK heatsink interface. | Use Scenario: Polarity reversal protection at 24V DC input of programmable logic controller. IC Role / Device Role / Timing Role: Common-cathode dual diode providing reverse-battery and reverse-connection safeguard. Use Value: Dual-anode structure allows single-component protection for redundant power inputs without cross-conduction risk. |

IC Role / Device Role / Timing Role: Clamp diode absorbing inductive energy during PWM dead-time intervals. Use Value: 175A surge rating handles repetitive motor/reactor energy dumps; 275pF capacitance avoids RF interference with communication lines. | Use Scenario: Reverse-polarity and load-dump protection in 12V automotive body control unit power rail. IC Role / Device Role / Timing Role: Input-stage Schottky clamp limiting reverse voltage to <35V during jump-start conditions. Use Value: Guard ring die withstands ISO 7637-2 pulse 1 (−150V/50ms) without degradation, eliminating need for discrete TVS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V16P35-M3/86A | Same 35V VRRM, 16A IO, but TO-220AC package; higher RθJC (4.0°C/W); no guard ring | Requires larger heatsink; lacks integrated transient protection; suited for legacy through-hole designs | Select if board uses through-hole mounting or existing TO-220 thermal infrastructure |
| ON Semiconductor MBR1635CT | Identical ratings and D²PAK package; slightly higher VF (0.57V @ 8A); RoHS compliant but not lead-free finish | Compatible footprint and thermal performance; minor efficiency penalty (~0.16W extra loss per element) | Select if supply chain requires ON Semi sourcing or accepts marginal VF increase |
Compared with V16P35-M3/86A and MBR1635CT, SBG1635CT-T-F uniquely combines guard ring transient hardening, lowest VF in class, and optimized D²PAK thermal interface-making it preferred for space-constrained, high-reliability SMT power stages despite its "Not Recommended for New Design" status due to newer Gen4 alternatives.

FAQ
Is SBG1635CT-T-F pin-compatible with SBG1640CT-T-F?
Yes - both share identical D²PAK package, pinout (Pin 1: Anode 1, Pin 2&4: Common Cathode, Pin 3: Anode 2), and mechanical dimensions. Only electrical differences exist: SBG1640CT-T-F has 40V VRRM and 0.57V VF at 8A, making it suitable for higher-voltage 36V systems but with marginally higher conduction loss.
What does "NOT RECOMMENDED FOR NEW DESIGN" mean for SBG1635CT-T-F?
This designation indicates Diodes Incorporated has released newer-generation Schottky rectifiers (e.g., SBG16xxCT-G series) with improved VF, lower leakage, or enhanced surge robustness. SBG1635CT-T-F remains fully qualified, in production, and supported for existing designs and legacy BOMs.
Can SBG1635CT-T-F be used without a heatsink?
No - its 16A rating assumes TC = 95°C, requiring heatsinking. At ambient temperature with no heatsink, derating curves limit continuous current to ≤4.5A. For unheatsinked use, consider lower-current alternatives like SBG835CT-T-F (8A rating).
Does SBG1635CT-T-F meet automotive AEC-Q101 requirements?
No - it is not AEC-Q101 qualified. While rated for −65°C to +125°C junction temperature and used in some automotive body electronics, it lacks stress-test validation per AEC-Q101. For automotive-grade applications, Diodes offers the APx1635CT series with full qualification.
