Product details
Overview
SBR30100CT from Diodes Incorporated is a 100 V, 30 A dual common-cathode super barrier rectifier in TO-220AB package, designed for high-efficiency AC/DC and DC/DC power conversion where low forward voltage (0.75 V @ 15 A, 125°C) and soft switching reduce conduction loss and EMI. It serves as output rectifier in server PSUs, telecom power supplies, and industrial SMPS.
For engineers reviewing the SBR30100CT datasheet, SBR30100CT pinout, SBR30100CT application, or SBR30100CT equivalent, key selection criteria include peak repetitive reverse voltage (100 V), average forward current per leg (15 A), thermal resistance (2°C/W junction-to-case), and RoHS-compliant green molding compound compatibility with high-temperature reflow.
Technical Context
This dual-leg super barrier rectifier integrates two independent anode terminals sharing a common cathode, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented SBR technology replaces conventional Schottky architecture with enhanced high-temperature stability-leakage remains ≤10 mA at 100 V and 125°C, unlike standard Schottkys which degrade rapidly above 100°C.
The device operates across –65°C to +175°C junction temperature range and supports non-repetitive surge currents up to 200 A (8.3 ms half-sine). Its soft recovery characteristic minimizes reverse recovery ringing in high-frequency switching topologies such as LLC resonant converters and active clamp forward designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in flyback or forward transformer secondary circuits. |
| IO (per leg) | 15 A - Continuous average forward current per anode; total device rating is 30 A with shared cathode configuration. |
| VF @ 15A, 125°C | 0.75 V - Confirmed forward drop under worst-case thermal condition; enables <1.1 W conduction loss per leg at full load. |
| IR @ 100V, 125°C | 10 mA - Reverse leakage at max voltage and elevated temperature; critical for standby power budgeting in energy-efficient PSUs. |
| RθJC | 2°C/W - Junction-to-case thermal resistance (TO-220AB); allows direct heatsink mounting for thermal management without isolation pads in most 1U server PSU layouts. |
| IFSM | 200 A - Non-repetitive surge rating; withstands inrush into bulk capacitors during cold-start without degradation. |
| TJ Range | –65°C to +175°C - Extended operational envelope supports under-hood automotive auxiliary supplies and industrial motor drive auxiliary rails. |
Pinout & Package
Package: TO-220AB - Insulated plastic case with copper leadframe, UL 94V-0 rated, matte tin-plated terminals solderable per MIL-STD-202 Method 208. Weight: ~1.85 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first rectifier leg | Accepts AC or switched DC input; electrically isolated from Anode 2 and Cathode in layout. |
| Cathode (Pin 2) | Common output node for both legs | Shared return path; must be routed with low-inductance, high-current capability for dual-leg operation. |
| Anode 2 (Pin 3) | Input terminal for second rectifier leg | Enables center-tapped transformer or dual-phase synchronous rectification; pin 1 and pin 3 are fully independent. |
Key Features
| Feature | Design Value |
|---|---|
| Patented Super Barrier Technology | Replaces Schottky metal-semiconductor junction with optimized epitaxial structure-enabling 100 V rating with VF comparable to 45 V Schottkys. |
| Soft, Fast Switching | No hard reverse recovery edge; reduces EMI generation and snubber losses in >100 kHz SMPS designs. |
| High-Temperature Stability | Leakage stays ≤10 mA at 125°C/100 V-supports compact, fanless power supplies operating near thermal limits. |
| Green Molding Compound | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); meets IPC-4101D/709B for environmentally constrained deployments. |
| Lead-Free & RoHS Compliant | Matte tin finish on copper leadframe; qualified for Pb-free reflow profiles up to 260°C peak. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT30100CT | Same electrical specs but ITO-220AB package with insulated tab (2000 V isolation); RθJC = 4°C/W. | Required when primary-secondary isolation is mandated (e.g., medical auxiliary supplies). | Select when heatsink must remain at primary potential or safety isolation >1500 VAC is required. |
| MBR30100CT | Standard Schottky; VF = 0.87 V @ 15A/25°C, IR = 50 mA @ 100V/125°C, TJ max = 150°C. | Lower cost but unsuitable for sustained 125°C operation or tight leakage budgets. | Acceptable only in lower-temperature, non-energy-critical applications with margin for higher VF and IR. |
Compared with SBRT30100CT, SBR30100CT offers 2°C/W lower thermal resistance and direct-mount heatsinking, while MBR30100CT trades off leakage and temperature capability for cost-making SBR30100CT optimal for thermally constrained, high-efficiency 100 V rectification.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR30100CT is rated for continuous operation from –65°C to +175°C junction temperature. This extended range enables use in high-ambient environments such as enclosed industrial drives or under-hood automotive auxiliary supplies without derating below 15 A per leg up to 125°C ambient with appropriate heatsinking.
How does the SBR30100CT differ from standard Schottky rectifiers in thermal performance?
Unlike standard Schottkys, the SBR30100CT maintains ≤10 mA leakage at 100 V and 125°C-where typical 100 V Schottkys exceed 100 mA. Its VF increases only marginally with temperature (0.72 V at 25°C → 0.75 V at 125°C), ensuring stable conduction loss across wide thermal swings.
Can the SBR30100CT be used in place of a single 30 A Schottky diode?
No-it is a dual-leg device with two independent anodes and one common cathode. It replaces two separate 15 A Schottkys in center-tapped or dual-phase configurations. Using it as a single 30 A rectifier would short the anodes unless externally wired in parallel with matched thermal paths and current-sharing resistors.
Is the TO-220AB package electrically insulated?
No-the TO-220AB package has an electrically conductive tab connected to the cathode (Pin 2). For isolation requirements, the ITO-220AB variant (SBR30100CTFP) provides 2000 VAC insulation between tab and terminals and is the recommended alternative when primary-secondary barrier integrity is mandatory.
