Product details
Overview
SBR40U60CTE from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier with 60V peak reverse voltage, 0.60V max forward voltage at 20A/25°C, 0.5mA max leakage at 60V/25°C, and TO-262 package; used for polarity protection and recirculating diode functions in industrial power supplies and DC motor drives.
For engineers reviewing the SBR40U60CTE datasheet, SBR40U60CTE pinout, SBR40U60CTE application, or SBR40U60CTE equivalent, key selection criteria include per-leg 20A average current rating, thermal resistance of 3°C/W junction-to-case, surge capability of 230A (8.3ms), RoHS-compliant matte tin terminals, and dual-anode/common-cathode configuration for half-bridge rectification.
Technical Context
This dual-diode rectifier integrates two independent SBR (Super Barrier Rectifier) elements in a single TO-262 package with shared cathode terminal, enabling synchronous half-wave or center-tapped full-wave topologies. Its guard ring die construction provides transient overvoltage immunity, while low VF minimizes conduction loss in high-current DC-DC output stages.
Designed for commercial-grade power conversion, it operates across –65°C to +150°C with 3°C/W RθJC when mounted on a specified heatsink (45mm × 20mm × 12mm black aluminum), and exhibits <0.57V VF at 20A/125°C - critical for thermally constrained 12V/24V industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in unidirectional DC bus clamping. |
| IO (per leg) | 20 A - Continuous average forward current per anode leg at TA = 25°C; total device rating is 40A with proper heatsinking. |
| VF (max) | 0.60 V @ 20A/25°C - Low conduction loss enables >95% efficiency in 12V output rectification at full load. |
| IFSM | 230 A - Non-repetitive surge current handling for motor startup or capacitor charging transients without failure. |
| IR (max) | 0.5 mA @ 60V/25°C - Minimal leakage preserves battery backup hold-up time and reduces standby power loss. |
| RθJC | 3 °C/W - Thermal resistance from junction to case; requires heatsink interface with ≤0.1°C·in²/W thermal resistance for 150°C max junction operation. |
Pinout & Package
Package: TO-262 - 3-pin molded plastic case with exposed metal tab (cathode-connected), UL 94V-0 rated, 1.355g weight, matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode Leg 1 | Input terminal for first rectifying path; electrically isolated from Pin 3; connects to AC input or switching node. |
| Pin 2 | Cathode (Common) | Shared cathode node for both diodes; must be connected to positive DC rail or heatsink (if electrically tied). |
| Pin 3 | Anode Leg 2 | Input terminal for second rectifying path; independent of Pin 1; enables dual-input or center-tap configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient immunity (IEC 61000-4-2 Level 4 compatible) without external TVS components. |
| Low VF at high temperature | 0.57V @ 20A/125°C ensures stable conduction loss in enclosed enclosures with ambient up to 85°C. |
| Lead-free & halogen-free | Meets RoHS 2 (2011/65/EU) and JEDEC JS709B green standards (<900ppm Br/Cl, <1000ppm Sb). |
| High surge rating | 230A IFSM supports 10× rated current surges during inductive load turn-off or cold-start conditions. |
Applications
| AC-DC Power Supply Output Stage | DC Motor Freewheeling Path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT40U60CT | Same electrical specs; TO-220AB package with insulated tab, higher RθJC (4.5°C/W). | Requires isolation hardware for heatsink mounting; less suitable for direct-tab thermal coupling. | Choose when electrical isolation from heatsink is mandatory and space allows larger footprint. |
| MBR4060CT | Standard Schottky; VF = 0.75V @ 20A/25°C, IR = 2.0mA @ 60V/25°C, no guard ring. | Higher conduction loss and lower transient robustness; unsuitable for high-surge environments. | Accept only if cost is primary constraint and surge immunity is not required. |
Compared with SBRT40U60CT, SBR40U60CTE offers lower thermal resistance and smaller footprint; versus MBR4060CT, it delivers 25% lower VF and 4× lower leakage - critical for efficiency-sensitive and thermally constrained designs.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, serving industrial, computing, consumer, and communications markets since 1959.
The SBR® Super Barrier Rectifier product line targets high-efficiency, high-reliability power conversion where Schottky performance is needed but silicon diode ruggedness is required - especially in automotive-qualified and industrial-grade applications.
FAQ
What is the maximum junction temperature for continuous operation?
The SBR40U60CTE has an operating junction temperature range of –65°C to +150°C. For continuous operation at full 20A per leg, thermal design must ensure TJ does not exceed 150°C - achievable with a 3°C/W heatsink and ≤10°C/W total system thermal resistance (including interface and ambient).
Is the cathode terminal electrically connected to the metal tab?
Yes, the metal tab (case) is internally connected to Pin 2 (common cathode). When mounted to a heatsink, the heatsink becomes part of the cathode circuit - requiring electrical isolation unless the heatsink is referenced to the positive rail.
Can this device replace a standard Schottky rectifier in existing designs?
Yes, with verification of layout clearance and thermal interface: SBR40U60CTE matches MBR4060CT's pinout and voltage/current ratings but offers lower VF and leakage. No schematic change is needed, though reduced thermal load may allow downsizing heatsinks.
Does the "U" in SBR40U60CTE indicate ultra-low VF?
No - the "U" denotes Diodes Incorporated's internal product family code for Super Barrier Rectifiers with enhanced surge capability and guard ring protection; VF improvement is a functional outcome, not a naming convention.
