Product details
Overview
SBR20U100CT from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 100V peak repetitive reverse voltage, featuring low forward voltage (0.63V typ. @ 20A, 25°C), soft fast switching, and high-temperature stability up to +175°C junction temperature. It is used in high-efficiency AC/DC front-end rectification and DC-DC secondary-side synchronous rectification in industrial power supplies.
For engineers reviewing the SBR20U100CT datasheet, SBR20U100CT pinout, SBR20U100CT application, or SBR20U100CT equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (2°C/W junction-to-case), surge current rating (200A IFSM), and TO220AB package compatibility with standard heatsinks.
Technical Context
This dual-diode rectifier integrates two independent SBR® (Super Barrier Rectifier) die in a single TO220AB package with common cathode configuration. Its patented barrier structure enables lower VF than Schottky diodes while maintaining higher reverse voltage capability and superior high-temperature leakage performance.
The device operates across -65°C to +175°C junction temperature range and supports soft recovery with minimal reverse recovery charge (Qrr not specified but implied by "soft, fast switching" claim and low IR at 125°C). It is optimized for continuous conduction mode (CCM) and critical conduction mode (CrCM) topologies where low conduction loss and thermal robustness are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum non-repetitive reverse voltage per leg; defines safe blocking capability in bridge or half-wave configurations. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg at TA = 25°C; total device rating is 20A with shared cathode. |
| VF (typ) | 0.63 V @ 20A, 25°C - Low conduction loss directly reduces power dissipation and improves system efficiency in high-current paths. |
| IFSM | 200 A - Peak non-repetitive surge current handling; supports inrush and transient overload without failure. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO220AB); enables precise heatsink sizing for 150°C max case temperature operation. |
| IR (max) | 25 mA @ 100V, 125°C - Controlled high-temp leakage ensures stable blocking under elevated ambient conditions. |
| TJ Range | -65°C to +175°C - Wide operating junction temperature range supports deployment in harsh industrial and automotive under-hood environments. |
Pinout & Package
Package: TO220AB - Insulated tab, 3-terminal through-hole package with copper leadframe, matte tin finish, UL 94V-0 molded plastic body, and 1.85g mass. Mounting requires mechanical isolation unless using insulated hardware.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifying path | Connected to AC input or transformer secondary winding; carries full forward current during positive half-cycle. |
| Anode 2 (Lead 2) | Input terminal for second rectifying path | Enables dual-input or center-tapped transformer interface; electrically isolated from Anode 1. |
| Cathode (Tab & Lead 3) | Common output node | Internally bonded to metal tab; must be electrically connected to system ground or output rail; provides primary thermal path to heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like low VF with PN-junction-like high VRRM and temperature stability-no trade-off between voltage rating and conduction loss. |
| Soft, fast switching | Minimizes EMI generation and voltage overshoot during turn-off, reducing need for snubbers in high-frequency SMPS designs. |
| High-temperature leakage control | IR ≤ 25 mA at 125°C enables reliable operation in enclosed power enclosures without forced air cooling. |
| RoHS-compliant & Green | Meets EU RoHS 3 (2015/863/EU), halogen-free (<900 ppm Br/Cl, <1000 ppm Sb), and antimony-free-compliant for eco-sensitive industrial deployments. |
Applications
| Server Power Supply | Industrial Motor Drive |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH05 | 50V VRRM, 20A IO, TO247AC package, higher VF (0.82V min @ 20A) | Limited to ≤50V systems; unsuitable for 100V bus designs requiring margin | Select only if system VDC ≤40V and TO247 mounting is preferred. |
| ON Semiconductor MUR20100CT | Ultrafast recovery (trr = 60ns), 100V VRRM, but higher VF (0.95V typ @ 20A) and no SBR soft-switching | Higher EMI risk in high-frequency converters; requires snubber network | Prefer when reverse recovery time is prioritized over conduction loss and EMI. |
Compared with VS-20CPH05 and MUR20100CT, SBR20U100CT uniquely balances 100V blocking, sub-0.65V conduction, and soft switching-making it optimal for high-efficiency, low-EMI, thermally constrained 100V rectification where both voltage margin and thermal headroom matter.

FAQ
What is the maximum allowable case temperature for SBR20U100CT in continuous operation?
The maximum case temperature is determined by the junction-to-case thermal resistance (RθJC = 2°C/W) and power dissipation. With a 150°C maximum junction temperature and 25°C ambient, sustained operation requires case temperature ≤125°C. Derating curves in Figure 4 confirm 10A per leg at 100°C ambient with adequate heatsinking.
Can SBR20U100CT be used in place of a standard 100V Schottky diode?
Yes-SBR20U100CT replaces 100V Schottkys with identical pinout and lower VF, but offers superior high-temperature leakage performance (25mA @ 125°C vs. >100mA for most Schottkys) and higher surge tolerance (200A IFSM). No layout change is needed for TO220AB footprints.
Is the metal tab electrically isolated in the TO220AB package?
No-the tab is internally connected to the common cathode (Pin 3) and is not insulated. Electrical isolation requires use of insulating shoulder washers and isolated mounting hardware. For fully isolated mounting, consider the ITO220AB variant (SBR20U100CTFP), which provides 2000VAC isolation between tab and leads.
Does SBR20U100CT require a minimum load or snubber circuit?
No minimum load is required. Due to its soft, fast switching characteristic, it typically eliminates the need for external snubbers in most 100kHz–500kHz SMPS designs. However, in hard-switched topologies above 1MHz or with highly inductive loads, empirical testing is recommended to verify voltage ringing remains within safe margins.
