Product details
Overview
SBR30A60CTB-13 from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier (SBR®) in TO263AB package, rated for 60V peak reverse voltage, with max 0.63V forward voltage at 15A/25°C and 0.5mA reverse leakage at 60V/25°C, designed for automotive polarity protection and recirculating diode applications.
For engineers reviewing the SBR30A60CTB-13 datasheet, SBR30A60CTB-13 pinout, SBR30A60CTB-13 application, or SBR30A60CTB-13 equivalent, key selection criteria include avalanche ruggedness, ultra-low VF at high current, low IR at elevated temperature, AEC-Q101 qualification status, and TO263AB thermal performance in constrained automotive power rails.
Technical Context
This device implements patented SBR® technology-distinct from Schottky and standard PN rectifiers-to deliver superior avalanche energy handling while maintaining low forward conduction loss. Its dual common-cathode configuration supports independent leg operation with shared thermal path to the exposed cathode tab.
Designed specifically for automotive-grade reliability, it features halogen- and antimony-free "Green" molding compound (UL 94V-0), matte tin–annealed copper leadframe, and IATF 16949-certified manufacturing. Thermal resistance junction-to-case is 2°C/W per leg when mounted on specified PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in 12V/24V automotive systems with load dump transients. |
| IO (Total) | 30 A - Total average rectified output current across both legs; enables high-current DC/DC output stage or motor recirculation without parallel devices. |
| VF MAX | 0.63 V @ 15A, 25°C - Ultra-low forward drop reduces conduction loss by >30% vs. standard fast recovery diodes, lowering thermal stress in compact layouts. |
| IR MAX | 0.5 mA @ 60V, 25°C - Low leakage ensures stable biasing and prevents thermal runaway during high-temperature engine bay operation (up to +150°C TJ). |
| RθJC | 2 °C/W per leg - Enables direct heatsinking via cathode tab; supports >15W dissipation per leg with minimal ΔT under continuous 15A load. |
| IFSM | 180 A (8.3ms half-sine) - Robust surge capability withstands inductive kickback from solenoids, relays, and brushed motors without degradation. |
Pinout & Package
Package: TO263AB (D²PAK), surface-mount, thermally enhanced with exposed cathode pad (Pin 3). Molded plastic case, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode A) | Anode of first diode leg | Connects to switched input rail (e.g., battery feed); carries full forward current of Leg A independently. |
| Pin 2 (Anode B) | Anode of second diode leg | Enables dual-path rectification or independent recirculation paths (e.g., H-bridge freewheeling); electrically isolated from Pin 1. |
| Pin 3 (Cathode) | Common cathode terminal | Exposed metal tab serving as thermal interface and electrical return; must be soldered to large copper pour for thermal management and low-inductance grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Superior avalanche ruggedness vs. Schottky diodes-enables reliable operation under repetitive overvoltage transients without parameter shift. |
| Ultra-low VF at high current | 0.63 V max @ 15A/25°C-reduces power loss to <9.5 W per leg, enabling smaller heatsinks and cooler PCB zones in space-constrained ECUs. |
| Low high-temp IR | 100 µA max @ 60V/125°C-prevents thermal runaway in under-hood environments where ambient exceeds +85°C. |
| AEC-Q101 qualified variant available | SBR30A60CTBQ is the automotive-compliant version-supports PPAP, change control, and IATF 16949 traceability for production vehicle programs. |
| Halogen- & antimony-free "Green" construction | Meets RoHS 3 (2015/863/EU) with Br+Cl <1500 ppm and Sb <1000 ppm-ensures compliance with global automotive material declarations (IMDS, CAMDS). |
Applications
| Automotive Polarity Protection | DC Motor Recirculation |
|---|---|
Use Scenario: Installed between battery and ECU power input to prevent damage from reverse battery connection during service or jump-starting. IC Role / Device Role / Timing Role: Unidirectional current gate-blocks reverse current flow while conducting forward current with minimal voltage penalty. Use Value: Eliminates need for series MOSFET or fuse-based protection; maintains <0.63V drop at 30A system peak, preserving voltage margin for 5V/3.3V regulators. | Use Scenario: Placed across brushed DC motor terminals in automotive seat/mirror/window actuators to clamp inductive flyback voltage. IC Role / Device Role / Timing Role: Freewheeling diode-provides low-impedance path for stored inductor energy during PWM turn-off. Use Value: Limits flyback spikes to ≤60V, protecting driver ICs; 180A surge rating handles worst-case stall currents without failure. |
| 12V/24V DC/DC Output Stage | LED Headlamp Power Supply |
Use Scenario: Used as synchronous rectifier replacement in secondary-side of isolated flyback or forward converters powering ADAS sensors or infotainment modules. IC Role / Device Role / Timing Role: High-efficiency output rectifier-conducts during transformer secondary conduction phase with minimal conduction loss. Use Value: Achieves >92% converter efficiency at 20A load due to 0.63V VF, reducing thermal load on primary-side controller and enabling smaller magnetics. | Use Scenario: Integrated into constant-current LED driver for adaptive front lighting systems (AFS), managing power delivery to high-brightness LED arrays. IC Role / Device Role / Timing Role: Output rectifier and current-path stabilizer-handles pulsed LED current while suppressing reverse recovery noise. Use Value: Near-zero reverse recovery charge (Qrr ≈ 0) eliminates switching noise coupling into sensitive camera/image processing circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT30A60CTB-13 | Same die, but with enhanced thermal pad design and tighter VF distribution (0.56–0.60 V typ); RθJC = 1.8°C/W. | Better suited for high-volume, thermally aggressive applications (e.g., engine control units) requiring tighter parametric consistency. | Select when thermal margin is critical and production volume justifies premium cost. |
| MBR3060CTG | Standard Schottky rectifier; VF = 0.75 V min @ 15A; no avalanche rating; IR = 1.0 mA @ 60V/25°C. | Lacks SBR's ruggedness for automotive transients; higher conduction loss and thermal drift limit use to non-safety-critical consumer-grade supplies. | Acceptable only for cost-sensitive, non-automotive designs with benign thermal environment and no load-dump exposure. |
Compared with SBRT30A60CTB-13, the SBR30A60CTB-13 offers balanced cost-performance for mainstream automotive modules, while MBR3060CTG trades ruggedness and efficiency for lower unit price-making it unsuitable for AEC-Q101–mandated functions.

FAQ
Is SBR30A60CTB-13 qualified to AEC-Q101?
No-the SBR30A60CTB-13 is the commercial-grade version. The automotive-qualified variant is SBR30A60CTBQ, which undergoes full AEC-Q101 stress testing, PPAP documentation, and IATF 16949 process controls. Both share identical electrical specs and TO263AB packaging.
What is the maximum continuous current per leg at +100°C ambient?
Based on the derating curve (Fig. 1), with RθJA = 16°C/W and TJ(max) = +150°C, the maximum continuous current per leg at +100°C ambient is approximately 10.5A. Total device current remains limited to 30A only if both legs operate below individual thermal limits.
Can SBR30A60CTB-13 replace a standard Schottky diode in an existing layout?
Yes-pin-compatible with TO263AB-packaged Schottkys like MBR3060CTG. However, its lower VF and negligible Qrr reduce thermal and EMI burden; verify layout copper area meets minimum 125 mm² per leg for optimal RθJC performance per datasheet note 5.
Does the cathode tab require electrical isolation from the heatsink?
No-the cathode (Pin 3) is the common output node and must be electrically connected to system ground or return rail. When using an external heatsink, use electrically conductive thermal interface material or ensure the heatsink is grounded to avoid floating potential and EMI issues.
