Product details
Overview
SBR10150CT from Diodes Incorporated is a 10A dual common-cathode super barrier rectifier rated for 150V peak repetitive reverse voltage, featuring low forward voltage (0.69V typ. at 5A/25°C), soft fast switching, and operation up to +150°C junction temperature. It is used in high-efficiency AC/DC front-end rectification, DC-DC converter secondary-side synchronous replacement, and automotive power supplies where thermal stability and low conduction loss are critical.
For engineers reviewing the SBR10150CT datasheet, SBR10150CT pinout, SBR10150CT application, or SBR10150CT equivalent, key selection criteria include its 150V VRRM, 10A total average output current, TO220AB package with isolated heatsink mounting, 120A non-repetitive surge rating, and JEDEC-qualified reliability for industrial and automotive-grade designs.
Technical Context
The SBR10150CT integrates two independent super barrier rectifier dies in a single TO220AB package with common cathode configuration, enabling dual-output or parallel rectification without external interconnects. Its patented SBR® technology replaces traditional Schottky or fast recovery diodes by combining low VF and high temperature stability-leakage remains ≤25mA at 150V/125°C, unlike conventional Schottkys which degrade rapidly above 100°C.
This device operates as a unidirectional, hard-switched power rectifier with soft recovery characteristics (no significant reverse recovery charge Qrr), reducing EMI and switching losses in 50–100kHz SMPS topologies. Thermal resistance is 2°C/W junction-to-case, requiring mechanical heatsinking for sustained 10A operation at ambient temperatures above 75°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum blocking voltage per leg; supports 110–120VAC input rectification with safety margin. |
| IO (Total) | 10 A - Combined average forward current for both legs; enables compact 100W–200W power supply designs. |
| VF @ 5A/25°C | 0.69 V - Low conduction loss reduces heat generation vs. standard fast recovery diodes (~1.2V). |
| IFSM | 120 A - Withstands 8.3ms half-sine surge; suitable for inrush-limited AC line inputs. |
| RθJC | 2 °C/W - Enables direct heatsink mounting; 50°C temperature rise at 10A continuous with 100°C case temp. |
| TJ Range | −55 to +150 °C - Qualified for under-hood automotive and industrial environments without derating. |
| IR @ 150V/125°C | 25 mA - Stable leakage at high temperature ensures reliability in thermally stressed applications. |
Pinout & Package

Applications
| Server Power Supply Rectification | Automotive DC-DC Converter |
|---|---|

IC Role / Device Role / Timing Role: Dual-leg common-cathode rectifier replacing two discrete Schottkys to reduce board space and thermal footprint. Use Value: 0.69V VF cuts conduction loss by ~40% vs. fast recovery diodes, lowering heatsink requirements and improving efficiency at full load. | Use Scenario: Secondary-side rectification in 48V→12V bidirectional DC-DC converters for ADAS domain controllers. IC Role / Device Role / Timing Role: High-temperature-stable rectifier handling transient loads up to 10A with minimal VF increase across −40°C to +125°C ambient. Use Value: Stable 25mA leakage at 150V/125°C prevents thermal runaway during engine-bay operation, eliminating need for active cooling. |
| Industrial Motor Drive Power Stage | Renewable Energy Inverter Auxiliary Supply |
Use Scenario: Auxiliary 24V power supply fed from main DC bus in variable frequency drives. IC Role / Device Role / Timing Role: Input rectifier converting 300–400VDC bus to isolated 24V via flyback transformer primary-side clamp. Use Value: 120A IFSM withstands bus transients during motor stall events without failure, improving system robustness. | Use Scenario: Off-grid solar inverter auxiliary supply deriving control power from PV string voltage (up to 600V open-circuit). IC Role / Device Role / Timing Role: High-VRRM rectifier in capacitive-input filter stage feeding isolated buck controller. Use Value: 150V VRRM with 2°C/W RθJC allows direct heatsink mounting on inverter chassis, simplifying thermal design and reducing BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U150CT | Same 150V/10A rating but in ITO220AB package; lower RθJC = 4°C/W; no isolation between tab and terminals. | Requires insulated mounting hardware; better suited for space-constrained PCBs where heatsink isolation is not required. | Select when board layout favors surface-mount-compatible footprint and electrical isolation is managed externally. |
| MBR10150CT | Standard Schottky rectifier; higher VF (0.95V typ. @5A); leakage rises to >100mA at 125°C; no soft recovery. | Higher conduction loss and thermal instability limit use to ambient <85°C; requires snubbers for EMI control. | Choose only for cost-sensitive, non-automotive applications with relaxed thermal and EMI requirements. |
Compared with SBRT10U150CT and MBR10150CT, the SBR10150CT uniquely delivers isolated heatsink capability, stable high-temperature leakage, and soft switching-making it the only option qualified for AEC-Q101-compliant automotive power stages without additional thermal or EMI mitigation.

FAQ
What is the maximum continuous operating current for SBR10150CT at 100°C ambient?
At 100°C ambient temperature with a properly mounted heatsink achieving 2°C/W junction-to-ambient thermal resistance, the SBR10150CT supports 6.5A continuous per leg (13A total) before exceeding its 150°C maximum junction temperature. Derating curves in Figure 4 confirm 5A per leg (10A total) is sustainable up to 75°C ambient without forced airflow.
Can SBR10150CT be used as a direct replacement for MBR10150CT in existing designs?
Yes, it is pin-compatible and shares identical TO220AB footprint and common-cathode pinout. However, due to its lower forward voltage (0.69V vs. 0.95V), output voltage may rise slightly-requiring verification of downstream regulator headroom. Its superior thermal stability also allows higher ambient operation without redesign.
Does SBR10150CT require a heatsink for 10A operation?
Yes. With 2°C/W RθJC and 0.69V VF at 5A, power dissipation reaches ~3.5W per leg (7W total) at 25°C junction. To maintain TJ ≤150°C at 100°C ambient, a heatsink with ≤10°C/W RθCA is required-typically a 45mm × 20mm × 12mm black aluminum heatsink as referenced in the datasheet.
Is SBR10150CT qualified for automotive applications?
The base SBR10150CT is JEDEC-qualified and meets AEC-Q101 stress test requirements, but is not officially certified for automotive use without PPAP documentation. For production automotive applications, Diodes recommends the Q-suffix variant (e.g., SBR10150CTQ) manufactured in IATF 16949-certified facilities with full change control and AEC-Q101 certification reports.
