Product details
Overview
SBR10U300CT-G from Diodes Incorporated is a 10A dual common-cathode super barrier rectifier in TO-220AB package, rated for 300V peak repetitive reverse voltage, with ultra-low forward voltage (0.71V typ. @10A, 25°C) and soft fast switching (trr = 25–35 ns). It delivers high-temperature stability up to +175°C junction temperature and is used in high-efficiency AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the SBR10U300CT-G datasheet, SBR10U300CT-G pinout, SBR10U300CT-G application, or SBR10U300CT-G equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJC = 2°C/W), reverse leakage at elevated temperature, surge current rating (150A IFSM), and RoHS/Green compliance status.
Technical Context
This device implements patented Super Barrier Rectifier (SBR®) technology - a planar-structured, low-barrier Schottky-like diode with enhanced blocking capability versus standard Schottky diodes. Its dual common-cathode configuration supports center-tapped transformer rectification or parallel-leg redundancy.
It operates with soft recovery characteristics (no hard reverse recovery snap), minimizing EMI in high-frequency switching converters. Thermal performance is optimized for direct heatsink mounting via the metal tab (isolated in ITO-220AB, non-isolated in TO-220AB), with derating defined from 150°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum allowable repetitive reverse voltage before breakdown; defines usable input voltage range in offline rectifiers. |
| IO (TC = 150°C) | 10 A - Average forward current rating at 150°C case temperature; sets continuous conduction capability with proper heatsinking. |
| VF (10A, 25°C) | 0.71 V typ. - Low conduction loss enabling >95% efficiency in 12V/24V output SMPS front-ends. |
| trr | 25–35 ns - Soft, fast reverse recovery minimizes switching losses and EMI generation in 100–500 kHz converters. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance enables compact heatsink design for 10A operation at ≤150°C case temp. |
| IFSM (8.3ms) | 150 A - Non-repetitive surge rating supports inrush current handling during cold-start of industrial power modules. |
| IR (300V, 125°C) | 25 mA max - Controlled high-temp leakage ensures stable blocking under thermal stress in enclosed enclosures. |
Pinout & Package
Package: TO-220AB - molded plastic case with isolated metal tab (electrically connected to cathode), UL 94V-0 rated, 1.85 g weight, matte tin-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Anode of first rectifier element | Accepts AC input phase 1; requires external snubber only if operating >200 kHz. |
| Pin 2 (Cathode) | Common cathode node | Output DC bus connection point; electrically tied to metal tab in TO-220AB variant. |
| Pin 3 (Anode 2) | Anode of second rectifier element | Accepts AC input phase 2 (e.g., center-tapped secondary); symmetrical layout enables balanced current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.71 V typ. @10A/25°C - reduces conduction loss by ~30% vs. standard FRD equivalents, lowering thermal load. |
| Soft fast switching | trr = 25–35 ns with no reverse recovery snap - suppresses voltage overshoot and EMI in high-frequency bridge rectifiers. |
| High-temperature stability | Rated TJ = –65°C to +175°C - supports operation in sealed industrial enclosures without forced air cooling. |
| Green / Halogen-free | Br <900 ppm, Cl <900 ppm, Sb <1000 ppm - meets IPC-1752A Class 3 material declaration requirements. |
| Lead-free & RoHS compliant | Meets EU Directive 2011/65/EU - qualified for automated reflow and wave soldering per J-STD-020. |
Applications
| Server Power Supply Rectification | Industrial Motor Drive Input Stage |
|---|---|
Use Scenario: High-density 1U server PSU using active clamp forward topology with 300VAC input. IC Role / Device Role / Timing Role: Dual common-cathode rectifier conducting full-wave output from center-tapped transformer secondary.

IC Role / Device Role / Timing Role: Single-phase leg in 6-pulse rectifier bridge handling 10A RMS line current. Use Value: 150A IFSM withstands motor startup surges; soft recovery prevents gate driver coupling noise in adjacent control circuits. |
| Telecom DC-DC Brick Input | Renewable Energy Inverter Auxiliary Supply |
Use Scenario: 48V telecom rectifier module converting -54V to -48V battery backup input to 12V logic rail. IC Role / Device Role / Timing Role: Reverse-polarity protection and input rectification in hot-swap capable auxiliary supply. Use Value: 25 mA IR max @125°C ensures reliable blocking during extended high-ambient operation in outdoor cabinets. | Use Scenario: Auxiliary 24V supply in solar string inverter, powered from PV array's 600V DC link via step-down converter. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in flyback-derived bias supply. Use Value: RθJC = 2°C/W allows direct mounting to chassis ground plane, eliminating discrete heatsink and saving 120 mm² PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U300CT | Same die, but in ITO-220AB package with isolated tab (2000 V isolation); RθJC = 4°C/W. | Required where primary-secondary isolation is mandated (e.g., medical auxiliary supplies). | Select when creepage/clearance or reinforced insulation is required; derate current by ~25% due to higher thermal resistance. |
| STPS10H100CG | 100V-rated Schottky; VF = 0.65V @10A but VRRM only 100V; no soft recovery (trr not specified). | Only suitable for low-voltage DC-DC inputs (<100V), not AC line rectification. | Use only in <100V systems where lowest VF is critical; avoid in 300V applications due to catastrophic failure risk. |
Compared with SBRT10U300CT and STPS10H100CG, SBR10U300CT-G provides optimal balance of 300V blocking, 10A current, ultra-low VF, and soft recovery - making it uniquely suited for universal-input industrial and telecom power supplies where reliability and EMI control are mandatory.

FAQ
Is SBR10U300CT-G pin-compatible with standard TO-220AB dual diodes like MUR1030?
No. While both use TO-220AB, SBR10U300CT-G has Anode–Cathode–Anode pinout (1–2–3), whereas MUR1030 uses Cathode–Anode–Anode. Incorrect substitution causes immediate short-circuit. Always verify pin configuration using the top-view mechanical drawing in DS30991 Rev.9.
Can SBR10U300CT-G replace a standard FRD in a 300V PFC boost diode position?
No. Though rated for 300V VRRM, its soft recovery and low VF are optimized for output rectification - not high-dV/dt, high-di/dt PFC boost stages. Use dedicated PFC diodes (e.g., DSSK100-015A) which specify Qrr and graded doping for zero-current turn-off.
What is the maximum recommended case temperature for continuous 10A operation?
The datasheet specifies IO = 10A at TC = 150°C. Operation above this temperature requires linear derating per Figure 4: at TC = 160°C, max IO drops to ~8.5A; at TC = 175°C, max IO is ~6.2A. Heatsink design must maintain TC ≤150°C under worst-case ambient and airflow conditions.
Does the "-G" suffix indicate electrical differences versus SBR10U300CT?
No. The "-G" suffix denotes Green molding compound (halogen/antimony-free), with identical electrical specs, thermal performance, and mechanical dimensions. Both versions share the same DS30991 datasheet and are functionally interchangeable in all designs meeting RoHS and IPC-1752A reporting requirements.
