Product details
Overview
SBR4060CT from Diodes Incorporated is a 40A dual common-cathode Super Barrier Rectifier rated for 60V peak reverse voltage, with typical forward voltage of 0.65V at 20A and 125°C, soft-switching behavior, and TO-220AB package optimized for high-efficiency AC/DC front-end and DC-DC secondary-side rectification in industrial power supplies.
For engineers reviewing the SBR4060CT datasheet, SBR4060CT pinout, SBR4060CT application, or SBR4060CT equivalent, key selection criteria include its low VF at high temperature, 280A non-repetitive surge rating, thermal resistance of 2°C/W (junction-to-case), RoHS-compliant lead-free finish, and compatibility with standard TO-220 heatsinking solutions.
Technical Context
This dual-diode rectifier integrates two independent SBR (Super Barrier Rectifier) die in a single TO-220AB thermally enhanced package with common cathode configuration. Its patented barrier structure enables lower forward voltage than Schottky diodes while maintaining superior high-temperature leakage performance and soft reverse recovery-critical for reducing EMI in high-frequency switching converters.
The device operates across –65°C to +150°C junction temperature range, supports 2000V isolation (ITO variant only), and exhibits <100µA leakage at 60V and 125°C. Derating curves confirm usable average forward current up to 20A per leg at 75°C ambient with appropriate heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in bridge or freewheeling configurations |
| IO (per leg) | 20 A - Continuous average forward current per anode leg at TA = 25°C with adequate heatsinking |
| IFSM | 280 A - Non-repetitive surge current capability (8.3ms half-sine); supports inrush and fault transient handling |
| VF @ 20A, 125°C | 0.65 V - Confirmed forward drop under worst-case thermal condition; enables <13W conduction loss per leg at full load |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO-220AB); enables direct mounting to heatsink without thermal interface degradation |
| IR @ 60V, 125°C | 100 µA - Reverse leakage at max voltage and max junction temperature; ensures minimal standby loss in offline SMPS |
Pinout & Package
Package: TO-220AB - Thermally optimized plastic case with isolated metal tab (cathode-connected), UL 94V-0 rated, 1.85g weight, matte tin-plated copper leadframe solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first rectifying path; electrically isolated from tab and Pin 2 |
| Pin 2 (Center) | Cathode (Common) | Shared output node for both diodes; internally bonded to metal tab for low-inductance thermal path |
| Pin 3 (Right) | Anode 2 | Input terminal for second rectifying path; electrically isolated from tab and Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR technology | Combines Schottky-like low VF with PN-junction leakage stability-enables 0.65V @ 20A/125°C without runaway risk |
| Soft, fast switching | Low reverse recovery charge (Qrr) and absence of hard reverse recovery snap-off-reduces EMI and snubber losses |
| High-temperature stability | Leakage remains <100µA at 60V/125°C-supports reliable operation in enclosed, unventilated industrial enclosures |
| RoHS & Green compliant | Lead-free, halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb)-meets EU environmental compliance mandates |
Applications
| Server Power Supply | Industrial Motor Drive |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 48V–54V output LLC resonant converters for rack-mounted servers. IC Role / Device Role / Timing Role: Dual common-cathode rectifier replacing discrete Schottkys to reduce conduction loss and improve efficiency above 85% at full load. Use Value: 0.65V VF at 125°C lowers per-leg conduction loss by ~1.2W vs. legacy 0.78V Schottky, directly improving system thermal margin. | Use Scenario: Freewheeling path in three-phase IGBT inverter stages driving 3–7.5kW AC induction motors. IC Role / Device Role / Timing Role: Clamp diode absorbing inductive kickback during IGBT turn-off; leverages soft recovery to suppress voltage overshoot. Use Value: Soft switching reduces dv/dt-induced gate ringing and eliminates need for RC snubbers on 600V-class IGBTs. |
| Telecom Rectifier Module | Renewable Energy Inverter |
Use Scenario: Input-stage AC rectification in -48V telecom rectifier modules operating continuously at 60°C ambient. IC Role / Device Role / Timing Role: High-current bridge leg component delivering 40A total output with forced-air cooling. Use Value: 20A/leg rating with 2°C/W RθJC allows stable operation at 135°C junction under sustained load-exceeding GR-1089 thermal requirements. | Use Scenario: DC bus clamping in 600V PV string inverters with transformerless topologies. IC Role / Device Role / Timing Role: Bidirectional energy recirculation path during MPPT transients and grid fault ride-through. Use Value: 280A IFSM withstands 10ms solar array short-circuit surges without degradation-validated per IEC 62109. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, medium-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS40H60CG | 40A, 60V Schottky; VF = 0.72V @ 20A/125°C; higher IR = 300µA @ 60V/125°C | Limited to ≤100°C ambient due to thermal runaway risk; unsuitable for sealed enclosures | Select when cost sensitivity outweighs thermal margin; avoid in high-ambient or unventilated designs |
| MBR4060CT | 40A, 60V Schottky; VF = 0.75V @ 20A/25°C; no specified VF at 125°C; RθJC = 2.5°C/W | Higher conduction loss at elevated temperature; requires larger heatsink for same thermal budget | Acceptable for lower-temperature commercial applications but not recommended for industrial-grade reliability |
Compared with STPS40H60CG and MBR4060CT, SBR4060CT delivers lower conduction loss at high temperature and superior thermal stability-making it the preferred choice for industrial, telecom, and renewable energy systems where long-term reliability under thermal stress is mandatory.

FAQ
Is SBR4060CT pin-compatible with standard TO-220AB dual-diode rectifiers?
Yes, SBR4060CT uses industry-standard TO-220AB mechanical dimensions and pinout: Pin 1 (Anode 1), Pin 2 (Common Cathode/tab), Pin 3 (Anode 2). It replaces legacy parts like MBR4060CT without PCB layout changes, though thermal and electrical performance exceeds them significantly.
What is the maximum continuous junction temperature for reliable operation?
The absolute maximum junction temperature is +150°C, and the device is characterized for stable operation up to this limit. Derating curves show usable 20A per leg up to 75°C ambient with a 2°C/W heatsink, confirming robust thermal headroom for industrial environments.
Does SBR4060CT require a heatsink in all applications?
A heatsink is required for continuous operation above ~5A per leg at room ambient. At full 20A/leg, thermal calculations using RθJC = 2°C/W and typical RθCA ≈ 10°C/W indicate >100°C junction rise-necessitating a properly mounted heatsink to stay within the 150°C limit.
How does SBR4060CT's soft switching benefit EMI performance?
Its soft reverse recovery minimizes high-frequency ringing and dv/dt spikes during turn-off, reducing broadband conducted EMI by up to 10dB in 30–100MHz range compared to fast recovery diodes-lowering filter component count and board space in Class B EMC-compliant designs.
