Product details
Overview
SBR15U100CTLQ from Diodes Incorporated is a 15A, 100V Super Barrier Rectifier (SBR®) diode in TO252 (DPAK) package, featuring 0.8 V max forward voltage at 7.5 A and 25°C, 0.1 mA max reverse leakage at 100 V and 25°C, and AEC-Q101 qualification for automotive polarity protection and recirculation applications.
For engineers reviewing the SBR15U100CTLQ datasheet, SBR15U100CTLQ pinout, SBR15U100CTLQ application, or SBR15U100CTLQ equivalent, key selection criteria include avalanche ruggedness (2800 W PARM, 192 mJ EAS), thermal resistance (2°C/W RθJC), high-temperature leakage performance, and IATF 16949 manufacturing compliance.
Technical Context
This SBR device uses patented Super Barrier Rectifier technology to deliver lower forward voltage than Schottky diodes while maintaining superior avalanche energy handling-192 mJ at 7.5 A with 10 mH inductance-and reduced thermal runaway risk due to low high-temperature IR (3.0 mA at 125°C, 100 V).
It operates across -55°C to +175°C junction temperature range, supports 100 A non-repetitive surge current (8.3 ms half-sine), and exhibits fast switching (15 ns tRR) with 200 pF junction capacitance at 4 V reverse bias-enabling efficient DC/DC and motor drive recirculation paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp circuits. |
| IO | 15 A - Average rectified output current; enables continuous conduction in high-current automotive power rails. |
| VF max | 0.80 V @ 7.5 A, 25°C - Ultra-low forward drop reduces conduction loss and improves system efficiency over standard Schottkys. |
| IR max | 0.10 mA @ 100 V, 25°C - Low leakage ensures stable blocking under nominal conditions; rises to 3.0 mA at 125°C. |
| tRR | 15 ns - Fast reverse recovery time minimizes switching loss and EMI in high-frequency PWM-driven loads. |
| EAS | 192 mJ - Non-repetitive avalanche energy rating confirms robustness against inductive kickback in motor control. |
| RθJC | 2 °C/W - Low junction-to-case thermal resistance supports high-power dissipation with minimal heatsinking. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal molded plastic package with matte tin annealed copper leadframe; UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry | Connected to input/power source side in polarity protection; must be routed with low-inductance path for surge handling. |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Common connection point for load return; electrically tied to exposed tab (Pin 3) for thermal and electrical grounding. |
| Tab / Exposed Pad (Pin 3) | Junction-to-case thermal path & cathode extension | Must be soldered to large copper pour for thermal management; provides direct cathode connection and lowers RθJC to 2°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| 100% avalanche tested | Guarantees each unit meets 2800 W peak avalanche power and 192 mJ energy rating-critical for automotive inductive load reliability. |
| Patented SBR® technology | Delivers Schottky-like VF with silicon-diode-level ruggedness, eliminating trade-off between efficiency and surge survivability. |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, HTRB, and ESD testing-supports PPAP documentation and IATF 16949 production. |
| Lead-free & halogen-free | Meets RoHS 3 (2015/863/EU) and "Green" definition (<900 ppm Br/Cl, <1000 ppm Sb); suitable for eco-sensitive vehicle platforms. |
Applications
| Polarity Protection | Motor Recirculation |
|---|---|
Use Scenario: Reverse-battery protection in 12 V/24 V automotive ECUs and infotainment systems. IC Role / Device Role / Timing Role: Unidirectional current gate placed between battery input and downstream regulator or microcontroller. Use Value: Prevents damage during jump-start misconnection; low VF minimizes voltage drop and heat generation at 15 A continuous load. | Use Scenario: Freewheeling path for brushed DC motors in power seats, HVAC actuators, and window lift modules. IC Role / Device Role / Timing Role: Clamp inductive kickback during MOSFET turn-off in H-bridge drivers. Use Value: 192 mJ EAS absorbs energy without failure; 15 ns tRR limits voltage overshoot and EMI generation. |

Use Scenario: Secondary-side rectification in isolated 48 V–12 V buck-boost converters for ADAS camera modules. IC Role / Device Role / Timing Role: High-efficiency synchronous rectifier replacement in fixed-frequency 200–500 kHz topologies. Use Value: 0.8 V VF reduces conduction loss vs. standard Si diodes; 200 pF CJ maintains switching integrity up to 500 kHz. | Use Scenario: Snubberless flyback clamp in interior ambient LED lighting with 100 V bus. IC Role / Device Role / Timing Role: Voltage clamp across primary winding during MOSFET off-time. Use Value: 100 V VRRM matches system rail; low IR prevents standby power waste; TO252 thermal pad enables compact layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT15U100CT-13 | Same die, identical VRRM/IO/VF, but TO220AC package with insulated tab; higher RθJC (3.5°C/W). | Requires mechanical isolation and larger heatsink; unsuitable for space-constrained PCB layouts. | Select when board-level thermal mass is limited but chassis mounting is available. |
| MBR15100CTG | Standard Schottky; 0.85 V VF max, no avalanche rating, 1000 µA IR at 125°C-higher leakage and no EAS spec. | Lacks AEC-Q101 qualification and fails under repeated inductive stress; not approved for safety-critical automotive use. | Acceptable only in non-automotive, low-reliability consumer power supplies with derated operation. |
Compared with SBRT15U100CT-13 and MBR15100CTG, the SBR15U100CTLQ uniquely combines TO252 mountability, AEC-Q101 compliance, and guaranteed avalanche ruggedness-making it the only choice for space-constrained, high-reliability automotive recirculation and protection where thermal and surge margins are non-negotiable.

FAQ
What is the maximum junction temperature rating for SBR15U100CTLQ?
The SBR15U100CTLQ has an operating junction temperature range of –55°C to +175°C, verified per AEC-Q101 stress test conditions. Its thermal resistance junction-to-case is 2°C/W, enabling reliable operation at full 15 A current when mounted on ≥4.57 mm × 2.60 mm copper pad with 2 oz. copper thickness per Diodes' recommended layout.
Is SBR15U100CTLQ suitable for synchronous rectification in high-frequency DC/DC converters?
No-it is a unidirectional rectifier, not a synchronous MOSFET controller or integrated driver. However, its 15 ns reverse recovery time and 200 pF junction capacitance make it suitable as a high-efficiency freewheeling diode in 200–500 kHz isolated converters where synchronous rectification is not implemented.
Does SBR15U100CTLQ require external snubbing in motor recirculation applications?
Not typically-its 192 mJ avalanche energy rating and 2800 W peak avalanche power allow it to safely absorb inductive energy from typical automotive motor loads (e.g., 12 V/24 V brushed DC motors with ≤10 mH inductance) without external snubbers, provided layout minimizes parasitic inductance and thermal design maintains TJ ≤ 175°C.
How does the SBR15U100CTLQ differ from standard Schottky rectifiers in thermal performance?
Unlike Schottky diodes, which suffer exponential IR increase above 125°C and risk thermal runaway, the SBR15U100CTLQ maintains only 3.0 mA leakage at 125°C and 100 V-less than 1/300th of typical Schottky leakage at that temperature-enabling stable operation in under-hood environments without forced cooling.
