SBR20A60CTBQ-13 개요
What is an SBR? A Super Barrier Rectifier is a low-forward-voltage-drop, majority-carrier rectifier that replaces standard Schottky diodes in high-current applications. Conceptually an SBR sits in the same family hierarchy as a Schottky diode -> rectifier diode -> discrete semiconductor, trading slightly higher reverse leakage for much lower VF and dramatically better surge and avalanche tolerance. The technology is now widely used in 12V/24V automotive power buses, where designers need both high current and high reliability under harsh thermal and electrical stress.
Key electrical performance includes a maximum repetitive peak reverse voltage (VRRM) of 60V, an average rectified forward current (IF(AV)) of 20A per device, a low typical forward voltage drop, and a maximum operating junction temperature of 150 degrees C. The SBR architecture lowers VF, improves high-temperature reverse-leakage stability versus Schottky diodes, and provides soft fast switching for low EMI. The TO-263 / D2PAK package is industry-standard for high-current surface-mount rectifiers and offers a low thermal-resistance path through the exposed tab.
The SBR20A60CTBQ-13 is built using Diodes' Super Barrier Rectifier process, which combines a low-voltage-drop rectifier die with high-avalanche-energy capability. The result is a diode that runs cooler than equivalently rated Schottky parts at high current and survives repetitive reverse-voltage transients that would destroy a conventional Schottky. The common-cathode dual-die layout halves conduction loss in ORing and freewheeling circuits by paralleling both dies into a single thermal mass.
Typical applications include automotive reverse-battery protection, DC-DC converter output rectification, low-voltage ORing and load-sharing, freewheeling diodes for motor drives and solenoids, and switch-mode power supply (SMPS) secondary-side rectification. The part is particularly attractive in 12V automotive ECU rails and 24V commercial-vehicle systems where Schottky diode leakage would otherwise force oversize heat sinks.
When designing with this part, keep the junction temperature below 150 degrees C and provide a copper land area of at least one square inch on the PCB to keep case-to-ambient thermal resistance in check at 20A continuous load. The SBR20A60CTBQ-13 is the automotive-grade (-Q) and 13-inch-reel version of the SBR20A60CT family, distinguished from the CTB (TB suffix) variant only by reel and change-control documentation.

Automotive Reverse-Battery Protection
The SBR20A60CTBQ-13's 60V VRRM and 20A continuous forward current make it ideal for automotive reverse-battery protection blocks on the 12V/24V vehicle bus. The AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing directly support OEM ECU designs where upstream load-dump transients up to 35V must be clamped without destroying the protection device. The SBR's lower VF versus a conventional Schottky diode reduces conduction loss during forward operation, so the part dissipates less heat at 20A continuous current. Place the SBR20A60CTBQ-13 in series with the main power feed between the battery terminal and the ECU input capacitor; the dual common-cathode configuration lets one die carry the load while the second can be paralleled for redundancy or used for an auxiliary load path on the same PCB land pattern.

DC-DC Converter Output Rectification
In non-isolated and isolated DC-DC converters such as 12V-to-5V buck or 24V-to-12V forward converters, the SBR20A60CTBQ-13 serves as the secondary-side output rectifier. Its 60V reverse rating comfortably exceeds the reflected secondary voltage stress of typical 12V and 24V primary-side converters, while the 20A forward current supports output powers in the 100W to 240W range. The SBR technology's lower VF versus a standard Schottky rectifier translates to higher conversion efficiency and cooler operation, especially at high output currents where diode conduction loss dominates. Use the dual common-cathode configuration in a center-tap forward converter topology, or parallel both dies for higher-current applications. The AEC-Q101 qualification is a major advantage for industrial-grade power supplies destined for harsh-environment installations.

Low-Voltage ORing and Load Sharing
The SBR20A60CTBQ-13's dual common-cathode configuration is well-suited to redundant 12V rail ORing in servers, networking equipment, and industrial power systems. Two power supplies can each drive one of the SBR's anodes, with the shared cathode delivering load current while preventing reverse current flow into a failed supply. The SBR's lower forward voltage drop versus a Schottky MOSFET combination minimizes voltage loss and improves load-share accuracy between supplies. At 20A continuous current, the SBR20A60CTBQ-13 comfortably handles most single-rail server and telecom loads; for higher currents, multiple SBR dice can be paralleled on a single PCB thanks to the matched die characteristics. The AEC-Q101 qualification also makes it attractive for redundant power systems in industrial and automotive applications.

Freewheeling Diode for Motor and Solenoid Drives
In automotive and industrial motor or solenoid drive circuits, the SBR20A60CTBQ-13 acts as a freewheeling diode to absorb inductive kickback when a switching element turns off. The 60V reverse rating handles typical 12V and 24V solenoid/relay coil transients with substantial margin, and the 20A continuous current rating covers most automotive and industrial actuator drive requirements. The SBR technology's fast soft switching reduces EMI compared to standard rectifier diodes, simplifying EMC compliance in sensitive automotive radio and sensor circuits. The common-cathode dual-die topology allows one SBR20A60CTBQ-13 to freewheel two independent half-bridge low-side switches, minimizing PCB area. Mount the package with sufficient copper pour to handle the 150 C junction temperature limit at 20A continuous load.

Switch-Mode Power Supply Secondary Rectification
The SBR20A60CTBQ-13 is well-suited to secondary-side rectification in switch-mode power supplies (SMPS) for telecom, industrial, and automotive applications. Its 60V reverse rating handles the reflected secondary voltage stress of most 12V and 24V-input flyback, forward, and half-bridge converters, while its 20A forward current supports output powers in the 100W to 300W range. The SBR's ultra-low forward voltage drop reduces conduction loss compared to a standard recovery rectifier, improving overall SMPS efficiency by 1-2 percent at high output currents. The dual common-cathode configuration is ideal for center-tapped transformer secondaries in forward converters. Combined with the AEC-Q101 automotive qualification, this part is a strong choice for SMPS modules destined for both automotive and harsh industrial environments.

Battery Charger Reverse-Polarity Blocking
In 12V and 24V lead-acid or lithium-ion battery charger designs, the SBR20A60CTBQ-13 provides reverse-polarity blocking and rectification in a single dual-die package. The 60V VRRM, 20A continuous current, and AEC-Q101 qualification collectively deliver the ruggedness and reliability that e-mobility and automotive charging products demand. The SBR technology's lower VF reduces heat generation during charging, improving overall charger efficiency and reducing thermal-management cost. Use both common-cathode dice in parallel for higher-current chargers, or use one die for reverse-polarity blocking and the other for a low-loss output rectifier on the same PCB footprint. The dual TO-263 D2PAK package simplifies mechanical mounting and provides a low-thermal-resistance path through the back tab.

주요 차별점
- Patented SBR technology with lower VF than Schottky (vs MBR2060CT (onsemi Schottky))
- AEC-Q101 qualified with full PPAP documentation (vs SBR20A60CTB-13 (industrial grade))
- High avalanche ruggedness compared to Schottky diodes (vs V30202C (Vishay Schottky))
설계 노트
At 20A continuous forward current with a typical VF of about 0.55 V (estimated), each die dissipates around 11 W; both dice operating in parallel sum to roughly 22 W at full dual load. The TO-263 D2PAK package thermal resistance is approximately 40 C/W on a 1 square-inch copper pad, producing a junction-to-ambient rise of about 880 C at full load. A copper pour of at least 1.5 square inches is the recommended floor for reliable operation; for sustained 20A dual-die conduction, consider doubling that or attaching a small clip-on heatsink to keep Tj below 150 C.
Lay out the TO-263 land pattern to maximise the back-tab copper connection - the back tab is the common cathode and the dominant thermal path. Use at least 2 oz copper on the cathode plane, and place thermal vias in a 3x3 grid under the D2PAK tab to drop thermal resistance into inner copper layers. Keep the two anode trace widths balanced so both dies share current equally in freewheeling or ORing applications.
Do not assume the SBR20A60CTBQ-13 has Schottky-level reverse leakage - SBR technology delivers much lower reverse leakage than Schottky but higher than standard rectifier diodes. Confirm that standby loss at 60V reverse bias stays within your thermal budget at high ambient temperatures (50 percent leakage increase above 100 C is typical). Also, note that the -Q automotive grade is the right choice whenever the production BOM is destined for an automotive ECU or an automotive-supplier sub-tier; the industrial-grade -B variant lacks IATF 16949 PPAP documentation.
