Product details
Overview
SBR20A60CTBQ-13 from Diodes Incorporated is a 20A, 60V Super Barrier Rectifier (SBR®) diode in TO263AB (D2PAK) package, designed for automotive polarity protection and recirculating applications. It delivers VF = 0.79 V @ 20A/25°C, IR = 0.5 mA @ 60V/25°C, IFSM = 180 A, RθJC = 4 °C/W, and is AEC-Q101 qualified for under-hood power management.
For engineers reviewing the SBR20A60CTBQ-13 datasheet, SBR20A60CTBQ-13 pinout, SBR20A60CTBQ-13 application, or SBR20A60CTBQ-13 equivalent, key selection criteria include ultra-low forward voltage at high temperature, low reverse leakage up to +125°C, avalanche ruggedness (EAS = 500 mJ), and IATF 16949 manufacturing compliance.
Technical Context
This dual-common-cathode SBR rectifier replaces Schottky diodes in 12V/24V automotive systems where thermal runaway risk limits conventional solutions. Its patented barrier structure enables VF as low as 0.47 V @ 10A/125°C while maintaining IR ≤ 0.14 mA @ 60V/25°C and ≤ 45 mA @ 60V/125°C.
It operates across –65°C to +150°C junction range with RθJC = 4 °C/W into heatsink and supports repetitive avalanche energy handling up to 7000 W (1 μs pulse). The TO263AB package provides robust thermal dissipation and meets J-STD-020 moisture sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum blocking voltage for 12V/24V automotive battery systems with load dump transients. |
| IO (per leg) | 20 A - Continuous DC current rating per anode leg at TA = 25°C with heatsink. |
| VF Max | 0.79 V @ 20A/25°C - Enables >95% efficiency in high-current DC/DC output stages. |
| IR Max | 0.5 mA @ 60V/25°C - Low leakage preserves system standby power budget in always-on modules. |
| IFSM | 180 A - Withstands motor stall or short-circuit surge without failure. |
| EAS | 500 mJ - Absorbs inductive kickback energy in solenoid/relay driver circuits. |
| RθJC | 4 °C/W - Enables direct mounting to PCB copper pour or external heatsink for thermal management. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, single-row 3-terminal configuration with exposed cathode tab for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first rectifier leg | Accepts positive input from alternator or battery feed; electrically isolated from A2. |
| Anode 2 (A2) | Input terminal for second rectifier leg | Enables dual-input redundancy or parallel operation; shares common cathode path. |
| Cathode (K) | Common output node | Exposed metal tab serves as primary thermal path and electrical return; must be soldered to large copper area. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with PN-junction ruggedness-no thermal runaway at +125°C. |
| 100% avalanche tested | Each unit validated to EAS = 500 mJ, ensuring reliability in inductive switching environments. |
| Low IR at high temperature | IR = 45 mA @ 60V/125°C - 3× lower than comparable Schottkys, reducing thermal drift risk. |
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, HTRB, and mechanical shock. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT20A60CTBQ-13 | Same die, enhanced thermal pad design; RθJC = 3.5 °C/W (vs. 4.0) | Better suited for compact layouts with limited heatsink area | Select when board space is constrained and junction temperature margin is critical |
| MBR2060CTG | Standard Schottky; VF = 0.82 V @ 20A/25°C, IR = 1.0 mA @ 60V/25°C, no AEC-Q101 | Limited to non-automotive industrial use due to higher leakage and no automotive qualification | Use only in cost-sensitive, non-safety-critical 12V systems with ambient <85°C |
Compared with SBRT20A60CTBQ-13 and MBR2060CTG, the SBR20A60CTBQ-13 offers optimal balance of automotive qualification, thermal performance, and leakage control-making it the default choice for AEC-Q101-compliant 20A rectification where reliability outweighs marginal cost savings.

FAQ
What is the maximum operating junction temperature for SBR20A60CTBQ-13?
The device is rated for TJ = –65°C to +150°C. At TA = +125°C with proper heatsinking (RθJC = 4 °C/W), it sustains IO = 20A continuously. Derating curves in Figure 5 confirm 12A max at +125°C ambient without heatsink.
Is SBR20A60CTBQ-13 compatible with lead-free reflow processes?
Yes-it features matte tin-plated copper leadframe, complies with J-STD-020 moisture sensitivity Level 1, and supports peak reflow temperatures up to 260°C. The "Green" molding compound meets UL 94V-0 flammability rating.
How does its reverse recovery time compare to standard fast recovery diodes?
tRR = 29 ns (measured at IF = 0.5A, IR = 1.0A, IRR = 0.25A), significantly faster than typical FRDs (>100 ns). This minimizes switching losses and EMI in high-frequency DC/DC converters operating above 200 kHz.
Can SBR20A60CTBQ-13 replace a dual-Schottky in existing designs?
Yes-the TO263AB footprint and dual-anode/common-cathode pinout match industry-standard dual Schottky packages. No layout change is needed, but verify thermal design since SBR's lower VF reduces heat generation by ~15% at full load.
