Product details
Overview
SBL1630CT from Diodes Incorporated is a 16A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 30V peak reverse voltage and 0.55V forward voltage at 8A/25°C, designed for low-voltage, high-frequency inverters, freewheeling, and polarity protection circuits.
For engineers reviewing the SBL1630CT datasheet, SBL1630CT pinout, SBL1630CT application, or SBL1630CT equivalent, key selection criteria include its 250A non-repetitive surge rating, 3.5°C/W junction-to-case thermal resistance, guard ring die construction for transient robustness, and RoHS-compliant tin-plated terminals.
Technical Context
This dual Schottky rectifier integrates two independent anode terminals (Pins 1 and 3) sharing a common cathode (Pin 2), enabling synchronous or independent half-wave rectification paths. Its guard ring die structure enhances ESD and transient immunity without external clamping components.
Optimized for low-loss operation, it delivers 0.55V VF at 8A and 25°C with 700pF typical junction capacitance at 4V reverse bias-critical for minimizing switching losses in 50–100kHz DC-DC and inverter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp applications. |
| IO | 16 A - Average rectified output current at TC = 95°C; requires heatsink mounting per RθJC = 3.5°C/W. |
| VFM | 0.55 V @ 8A, 25°C - Low conduction loss enables >92% efficiency in 3.3–12V output converters. |
| IFSM | 250 A @ 8.3ms - Withstands motor startup surges and capacitor inrush without failure. |
| RθJC | 3.5 °C/W - Enables thermal design with standard TO-220 heatsinks for continuous 12–16A operation. |
| Cj | 700 pF @ 4V - Limits high-frequency displacement current; suitable for <100kHz switching topologies. |
Pinout & Package
Package: TO-220AB molded plastic case (UL 94V-0), 2.24g weight, tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent input path for first rectifier leg; marked "+" on body. |
| Pin 2 | Common Cathode | Shared output node for both diodes; electrically connected to metal tab (case). |
| Pin 3 | Anode 2 | Independent input path for second rectifier leg; marked "+" on body. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity without external TVS, reducing BOM count in industrial power supplies. |
| Low VF (0.55V @ 8A) | Reduces conduction loss by ≥35% vs. comparable Si PN rectifiers, lowering thermal load in enclosed enclosures. |
| 250A IFSM rating | Supports direct connection to 12V battery rails with motor or solenoid loads without series fusing. |
| TO-220AB with metal tab | Enables direct heatsink mounting via case (Pin 2), simplifying thermal management in space-constrained 1U power modules. |
Applications
| DC-DC Converter Output Stage | Automotive Battery Polarity Protection |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated 12V→3.3V/5V flyback converters. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier providing low-loss unidirectional current path with shared cathode return. Use Value: 0.55V VF minimizes conduction loss at 8–12A loads, improving full-load efficiency by 2.1% over legacy 40V Schottkys. | Use Scenario: Reverse-polarity protection for 12V automotive ECUs powered directly from battery terminals. IC Role / Device Role / Timing Role: Common-cathode dual diode configured as OR-ing device to block reverse current during incorrect battery connection. Use Value: 250A surge rating withstands jump-start transients; guard ring die prevents latch-up during 100V load-dump events. |
| Industrial Inverter Freewheeling | AC-DC Adapter Input Bridge Clamp |
Use Scenario: Freewheeling path across IGBTs in 24V servo drive H-bridge outputs. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent clamping of upper/lower leg inductive kickback. Use Value: 700pF Cj limits displacement current during 20kHz PWM switching, reducing EMI filter burden. | Use Scenario: Snubberless clamp across bridge rectifier output in universal-input 90–264VAC adapters. IC Role / Device Role / Timing Role: Common-cathode dual diode used as low-VF clamp to absorb transformer leakage energy. Use Value: 3.5°C/W RθJC enables direct heatsink mounting, sustaining 16A clamping current without derating at 70°C ambient. |
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, 0.54V VF @ 8A, but TO-220AC package (isolated tab). | Requires insulated mounting hardware; unsuitable where case must be electrically tied to cathode. | Select when electrical isolation of heatsink is required. |
| ON Semiconductor MBR1630CT | Identical ratings and TO-220AB pinout, but higher 0.62V VF @ 8A and no guard ring. | Lower surge immunity; may require external TVS in harsh automotive environments. | Select when cost sensitivity outweighs transient robustness requirements. |
Compared with VS-16CTH03-M3 and MBR1630CT, the SBL1630CT uniquely combines guarded die construction, metal-tab cathode connectivity, and sub-0.56V forward drop-making it optimal for thermally constrained, transient-prone 12–24V industrial and automotive power stages.

FAQ
Is the SBL1630CT RoHS compliant?
Yes, the SBL1630CT features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC revision 13.2.2003, with exemptions applied for glass and high-temperature solder per Annex Notes 5 and 7. Tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements.
What is the thermal interface requirement for the metal tab?
The metal tab (Pin 2, common cathode) must be mounted to a heatsink using thermally conductive insulating pads or paste if electrical isolation is needed; direct metal-to-metal contact is permitted when the heatsink is referenced to the cathode potential. Thermal resistance assumes full surface contact per JEDEC JESD51-14 guidelines.
Can SBL1630CT replace SBL1640CT in a 40V design?
No-SBL1630CT has a 30V VRRM rating and is not rated for 40V blocking. Using it in a 40V circuit risks catastrophic reverse breakdown under transient or ripple conditions. The SBL1640CT (40V) or SBL1645CT (45V) must be selected for designs requiring ≥40V working peak reverse voltage.
Does the guard ring affect forward conduction characteristics?
No-the guard ring is a passive edge termination structure that does not alter forward conduction parameters. It improves reverse-biased junction stability and transient immunity without increasing VF, RθJC, or leakage current beyond datasheet-specified values at 25°C and 100°C.
