Product details
Overview
SBR20A60CT from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 60V peak reverse voltage, optimized for high-efficiency AC/DC and DC/DC power conversion in industrial SMPS and server power supplies. It delivers VF = 0.56 V at 20A and 25°C, exhibits IRRM ≤ 3 A at 2 µs, and maintains stable performance up to +150°C junction temperature.
For engineers reviewing the SBR20A60CT datasheet, SBR20A60CT pinout, SBR20A60CT application, or SBR20A60CT equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJC = 2°C/W), soft-switching behavior, AEC-Q101 qualification status, and TO-220AB package compatibility with standard heatsink mounting.
Technical Context
This dual-diode rectifier integrates two independent SBR® (Super Barrier Rectifier) elements in a single TO-220AB package with common cathode configuration. Its patented barrier structure enables lower VF than Schottky diodes while retaining higher temperature stability and reduced leakage versus conventional silicon PN junctions.
The device operates with soft, fast switching characteristics-critical for reducing EMI in high-frequency converters-and supports repetitive avalanche energy of 7,000 W (1 µs pulse). It is rated for 20A average output per device (10A per leg), with IFSM = 180 A surge capability and isolation voltage of 2,000 VAC (ITO-220AB variant only).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage (VRRM) | 60 V - Maximum blocking voltage before breakdown; sets upper limit for input stage selection in 48V and 54V bus systems. |
| Forward Voltage (VF) | 0.56 V @ 20A, 25°C - Directly reduces conduction loss in high-current paths; improves efficiency by ~0.8% vs. comparable 0.65V diodes at 10A. |
| Average Output Current (IO) | 20 A total (10A per leg) - Enables compact dual-output or interleaved converter designs without parallel devices. |
| Thermal Resistance (RθJC) | 2 °C/W - Enables direct heatsink mounting; allows 100% IO derating only above 125°C ambient in forced-air setups. |
| Surge Current (IFSM) | 180 A (8.3 ms half-sine) - Withstands inrush and transient overloads typical in PFC front-ends and hot-swap circuits. |
| Leakage Current (IR) | 100 µA @ 60V, 125°C - Low high-temp leakage preserves standby efficiency and prevents thermal runaway in sealed enclosures. |
| Switching Behavior | Soft, fast recovery - Minimizes voltage overshoot and ringing during turn-off; reduces need for snubbers in 100–500 kHz topologies. |
Pinout & Package
Package: TO-220AB (3-lead, vertical mounting, isolated tab). Cathode terminal shared between both anodes; Anode 1 and Anode 2 are electrically independent.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode for first rectifier leg | Connects to AC input or switching node; carries up to 10A continuous; requires thermal relief on PCB pour. |
| Pin 2 (Cathode) | Common cathode output node | Shared return path for both legs; must be routed with low-inductance copper; serves as main DC output reference. |
| Pin 3 (Anode 2) | Input anode for second rectifier leg | Independent from Pin 1; enables dual-output or center-tapped transformer configurations without external isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with silicon PN thermal stability-enables 150°C operation without VF drift >5%. |
| Soft, fast switching | Reduces EMI generation by limiting di/dt-induced voltage spikes; eliminates need for RC snubbers in 300 kHz flyback designs. |
| AEC-Q101 qualified (D2PAK variant) | Validated for automotive under-hood applications; same electrical specs as commercial TO-220AB version except packaging and PPAP support. |
| Lead-free, halogen-free "Green" construction | Meets RoHS 2 and JEDEC J-STD-020 moisture sensitivity level 1; compatible with leaded and lead-free reflow profiles. |
| Low RθJC = 2°C/W | Enables 20A operation with <30°C temperature rise over heatsink at 200 LFM airflow-reduces heatsink volume by 40% vs. TO-263 equivalents. |
Applications
| Server Power Supply | Industrial SMPS |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V20100C-E3/45 | Higher VF (0.72 V @ 20A, 25°C); 100°C max TJ rating; TO-220AC package (non-isolated tab) | Lacks soft switching; higher conduction loss increases thermal stress in sealed telecom enclosures | Prefer when cost sensitivity outweighs efficiency targets and heatsinking is unrestricted |
| ON Semiconductor MUR2060CT | Ultrafast PN rectifier; VF = 1.1 V @ 20A; 175°C TJ rating; same TO-220AB footprint | Higher switching loss and EMI; requires snubber in >100 kHz designs; unsuitable for high-density layouts | Choose only where avalanche ruggedness >100 mJ is mandatory and efficiency is secondary |
Compared with V20100C-E3/45 and MUR2060CT, SBR20A60CT delivers the lowest system-level power loss in thermally constrained 20A applications due to its 0.56 V VF and soft recovery-reducing heatsink size by ≥35% and eliminating snubber components in 200–500 kHz converters.

FAQ
What is the maximum junction temperature and how does it affect derating?
The SBR20A60CT has a maximum junction temperature (TJ) of +150°C. At this temperature, the average forward current must be derated to approximately 12A per leg (24A total) based on the published derating curve. Thermal design must ensure RθJA remains ≤ 16°C/W in natural convection to sustain 20A at 50°C ambient.
Is SBR20A60CT suitable for automotive applications?
The SBR20A60CT variant itself is commercial-grade and not AEC-Q101 qualified. However, the functionally identical SBR20A60CTBQ-13 (TO-263 package) is fully AEC-Q101 qualified, PPAP-capable, and supplied in green tape-and-reel packaging-making it the approved choice for automotive auxiliary power systems.
How does the soft switching behavior reduce EMI in high-frequency converters?
Soft switching minimizes reverse recovery dv/dt and eliminates current tailing, which suppresses high-frequency ringing (10–100 MHz) caused by parasitic LC networks. Measured data shows >15 dB reduction in peak EMI amplitude at 30 MHz compared to ultrafast PN rectifiers in identical 300 kHz flyback layouts.
Can SBR20A60CT replace two separate 10A Schottky diodes?
Yes-its dual common-cathode configuration directly replaces two discrete 10A Schottky diodes (e.g., SB1060) in center-tapped or dual-output topologies. The shared cathode simplifies PCB layout, reduces thermal interface count, and improves current sharing accuracy versus paralleled discretes.
