Product details
Overview
SBR10U150CT from Diodes Incorporated is a 10A dual common-cathode Super Barrier Rectifier with 150V peak repetitive reverse voltage, ultra-low forward voltage (0.63V typ. @ 10A, 25°C), and soft fast switching capability-designed for high-efficiency AC/DC secondary-side rectification in server power supplies and telecom rectifiers.
For engineers reviewing the SBR10U150CT datasheet, SBR10U150CT pinout, SBR10U150CT application, or SBR10U150CT equivalent, key selection criteria include forward voltage drop at 10A, thermal resistance (2°C/W junction-to-case), leakage current at 125°C, TO-220AB package compatibility, and RoHS/Green compliance status.
Technical Context
This dual-leg rectifier integrates two independent super barrier diodes in a single TO-220AB package with common cathode configuration, enabling synchronous-like efficiency without gate drive circuitry. Its patented SBR technology replaces Schottky structures with lower VF and superior high-temperature stability.
It operates across –65°C to +175°C junction temperature, supports non-repetitive surge currents up to 150A (8.3ms half-sine), and maintains <25mA reverse leakage at 150V and 125°C-critical for high-ambient industrial and telecom power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150V - blocks DC and transient voltages up to 150V in bridge or center-tap configurations |
| IO (per leg) | 5A continuous - delivers 5A average rectified current per anode leg at 25°C ambient with heatsink |
| VF @ 10A, 25°C | 0.63V typical - reduces conduction loss by ~30% vs. standard Schottky diodes at same current |
| RθJC | 2°C/W - enables direct mounting to heatsink for thermal management in compact 1U power supplies |
| IR @ 150V, 125°C | 25mA max - ensures low standby loss and stable operation in high-temp base station PSUs |
| IFSM | 150A - withstands inrush surges during hot-plug events in redundant power modules |
Pinout & Package
TO-220AB package: insulated tab, 3-terminal through-hole mount with common cathode configuration. Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first rectifying leg; connects to transformer secondary winding or input node |
| Pin 2 | Cathode (common) | Shared output node for both legs; ties to +VOUT rail and heatsink (electrically isolated in TO-220AB) |
| Pin 3 | Anode 2 | Input terminal for second rectifying leg; used in center-tapped or dual-output topologies |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 0.63V typ. @ 10A, 25°C - directly lowers conduction loss and improves system efficiency >1% in 48V output PSUs |
| High-temperature stability | Leakage remains ≤25mA at 125°C - avoids thermal runaway in unventilated enclosures |
| Soft fast switching | Low reverse recovery charge (Qrr) - minimizes EMI and snubber losses in high-frequency LLC resonant converters |
| RoHS & Green compliant | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb) - meets IPC-1752A Tier 1 reporting requirements |
Applications
| Server AC/DC Power Supply | Telecom Rectifier Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U150CT | Same die, ITO-220AB package with insulated tab; RθJC = 4°C/W vs. 2°C/W | Better isolation (2000V AC), but higher thermal resistance limits use in space-constrained 1U designs | Select when electrical isolation >2000V is required and thermal headroom allows 2× junction rise |
| MBR10150CT | Standard Schottky; VF = 0.85V @ 10A, 25°C; IR = 50mA @ 125°C | Higher conduction loss and leakage reduce efficiency in high-temp, high-density layouts | Acceptable only where cost sensitivity outweighs 0.8–1.2% efficiency penalty and thermal margin exists |
Compared with SBRT10U150CT and MBR10150CT, the SBR10U150CT delivers optimal balance of low VF, robust high-temperature leakage performance, and TO-220AB thermal efficiency-making it preferred for thermally constrained, high-efficiency telecom and server power designs.

FAQ
What is the maximum junction temperature rating for SBR10U150CT?
The SBR10U150CT has a specified operating junction temperature range of –65°C to +175°C. This rating is validated per JEDEC JESD22-A108 and confirmed in the DS30954 datasheet Rev.9. The device achieves this via proprietary SBR epitaxial structure and copper leadframe construction, enabling reliable operation in sealed telecom enclosures and industrial motor drives without active cooling.
Is SBR10U150CT pin-compatible with standard TO-220AB dual diodes like MBR10150CT?
Yes-SBR10U150CT uses identical TO-220AB mechanical dimensions and 3-pin common-cathode pinout (Anode1–Cathode–Anode2) as MBR10150CT. Mounting hole spacing, lead pitch, and tab geometry match exactly per Diodes' package drawings, allowing direct PCB footprint reuse without layout changes.
Does SBR10U150CT require a heatsink for 10A operation?
Yes-continuous 10A operation requires a heatsink. With RθJC = 2°C/W and max TJ = 175°C, even at 25°C ambient, junction temperature would exceed 175°C without thermal management. A 45mm × 20mm × 12mm black aluminum heatsink (as referenced in Note 7 of DS30954) is recommended to maintain TJ ≤ 125°C at full load.
How does the "Green" designation affect SBR10U150CT's material composition?
The "Green" designation certifies halogen- and antimony-free construction: bromine and chlorine each <900ppm, total Br+Cl <1500ppm, antimony <1000ppm. This complies with IPC-1752A and EU Directive 2011/65/EU (RoHS 2), verified by Diodes' internal material testing and third-party lab reports per IEC 62321.
