Product details
Overview
SBR1045CTLQ from Diodes Incorporated is a 10A Super Barrier Rectifier (SBR®) diode designed for high-efficiency, high-reliability automotive power conversion. It features a 45V peak repetitive reverse voltage, 0.55V max forward voltage at 5A/25°C, 0.3mA max reverse leakage at 45V/25°C, AEC-Q101 qualification, and TO252 (DPAK) surface-mount package. It is deployed in DC-DC converters, DC/AC inverters, and AC/DC power supplies where low conduction loss and thermal stability are critical.
For engineers reviewing the SBR1045CTLQ datasheet, SBR1045CTLQ pinout, SBR1045CTLQ application, or SBR1045CTLQ equivalent, key selection criteria include its ultra-low VF for efficiency gain, high-temperature IR performance up to +125°C, avalanche ruggedness (2650W PARM), AEC-Q101 compliance, and TO252 thermal resistance (RθJA = 47°C/W).
Technical Context
The SBR1045CTLQ employs patented Super Barrier Rectifier technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior reverse leakage control at elevated temperatures. Its structure enables stable operation up to +150°C junction temperature with minimal thermal runaway risk.
It delivers 90A non-repetitive surge current capability and 100mJ avalanche energy rating under defined test conditions (IAS = 5A, L = 10mH), supporting robust transient handling in automotive switching topologies such as synchronous buck and boost converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 45 V - Maximum blocking voltage in repetitive reverse bias; defines safe operating range in 12V/24V automotive systems. |
| IO (AV) | 10 A - Continuous average forward current per leg; supports high-power DC-DC stages without forced cooling. |
| VF Max | 0.55 V @ 5A, 25°C - Ultra-low conduction loss reduces power dissipation and improves system efficiency by ~1–2% vs. standard Schottkys. |
| IR Max | 0.3 mA @ 45V, 25°C - Low leakage ensures minimal standby loss and stable performance across temperature. |
| tRR | 15 ns - Fast recovery time minimizes switching losses and EMI in high-frequency (>100 kHz) converters. |
| RθJA | 47 °C/W - Thermal resistance enables 6W+ power dissipation on standard 2oz copper PCBs without heatsink. |
| EAS | 100 mJ - Avalanche energy rating supports reliable operation during inductive turn-off transients. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal plastic package with exposed cathode pad for enhanced thermal dissipation. Molded green compound, UL 94V-0 rated, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to input/high-side rail; must be routed with low-inductance trace for high-di/dt operation. |
| Cathode (Pin 2) | Forward current exit / common output node | Exposed metal tab - electrically and thermally connected to cathode; requires soldered thermal pad for RθJA compliance. |
| Source / Drain Tab (Pin 3) | Thermal & electrical cathode connection | Integral with Pin 2; provides primary heat path to PCB; not isolated - must be referenced to system ground or output potential. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Enables Schottky-like VF with Si diode-level IR stability - eliminates trade-off between efficiency and high-temp reliability. |
| 100% avalanche tested | Each unit validated for 2650W peak avalanche power - ensures field robustness in unclamped inductive switching events. |
| AEC-Q101 qualified | Validated for automotive-grade stress tests (HTGB, HTRB, TCT, etc.) - supports PPAP submission and IATF 16949 production. |
| Green, halogen-free construction | <900 ppm Br/Cl, <1000 ppm Sb - meets global environmental regulations without compromising thermal or electrical performance. |
Applications
| Automotive DC-DC Converters | Onboard Charger (OBC) Rectification |
|---|---|
Use Scenario: High-current 12V-to-48V bidirectional DC-DC converter in mild-hybrid vehicles. IC Role / Device Role / Timing Role: Output rectifier in synchronous buck-boost topology, conducting continuous 10A load current. Use Value: 0.55V VF reduces conduction loss by ~1.2W vs. conventional Schottky, lowering thermal stress and enabling smaller heatsinks. | Use Scenario: Secondary-side rectification in 3.3kW OBC AC/DC stage feeding battery management system. IC Role / Device Role / Timing Role: Freewheeling diode in phase-shifted full-bridge, handling 5–8A RMS with high di/dt. Use Value: 15ns tRR limits reverse recovery charge (Qrr), reducing switching loss and EMI generation at 100–200 kHz operation. |
| EV Traction Inverter Auxiliary Supply | Industrial 24V Power Module |
Use Scenario: Isolated auxiliary power supply (12V/2A) derived from main inverter DC-link in EV traction inverters. IC Role / Device Role / Timing Role: Output rectifier in flyback converter operating at 200 kHz with wide ambient range (−40°C to +125°C). Use Value: 0.3mA IR at 125°C prevents thermal runaway under sustained high-temp operation - critical for under-hood placement. | Use Scenario: Input rectification in DIN-rail mounted 24V industrial power module for PLC and I/O systems. IC Role / Device Role / Timing Role: Primary rectifier in bridge configuration, delivering 10A continuous output with 45V derating margin. Use Value: TO252 package with 47°C/W RθJA allows full-rated current on standard FR4 PCB - eliminates need for custom thermal vias or metal-core boards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10E45-M3/57T | Same 45V VRRM, 10A IO, but VF = 0.62V @ 5A - 70mV higher conduction loss. | Lacks AEC-Q101 qualification; rated only for industrial temp range (−65°C to +175°C), no PPAP support. | Select when automotive qualification is not required and cost sensitivity outweighs 0.5–0.8% efficiency penalty. |
| ON Semiconductor NRVB1045CTT4G | Identical 45V/10A rating, VF = 0.57V @ 5A; slightly higher IR (0.5mA @ 45V/25°C). | AEC-Q101 qualified but uses TO-220AB package - larger footprint and higher RθJA (50°C/W), limiting power density. | Prefer for legacy through-hole designs or where TO-220 mechanical mounting is mandated; avoid in space-constrained SMT layouts. |
Compared with VS-10E45-M3/57T and NRVB1045CTT4G, the SBR1045CTLQ offers the lowest VF among AEC-Q101-qualified 45V/10A SBRs, best-in-class thermal resistance in DPAK, and verified avalanche ruggedness - making it optimal for high-density, high-reliability automotive power stages.

FAQ
What is the maximum junction temperature rating for SBR1045CTLQ?
The SBR1045CTLQ has a specified operating junction temperature range of −55°C to +150°C. This rating is validated per AEC-Q101 stress testing and supported by its 47°C/W thermal resistance and low IR drift up to +125°C - enabling use in under-hood automotive environments without derating below 10A at ambient ≤ +85°C.
Is SBR1045CTLQ pin-compatible with standard TO252 Schottky diodes?
Yes - the SBR1045CTLQ uses the industry-standard TO252 (DPAK) outline with identical 3-pin configuration (anode, cathode, thermal tab). Its pin assignment matches JEDEC MO-263, allowing direct PCB footprint reuse from devices like SB1040 or MBR1045, provided thermal pad layout complies with Diodes' recommended 4.57 mm × 2.60 mm copper area.
Does SBR1045CTLQ require a heatsink in typical 10A applications?
No external heatsink is required when mounted on a standard 2"×2", 2oz copper PCB per Note 5 in the datasheet. At 10A and 25°C ambient, power dissipation is ~5.5W (10A × 0.55V), resulting in ~260°C junction rise (47°C/W × 5.5W); however, actual board-level thermal performance typically achieves RθJA ≈ 35°C/W, keeping TJ < 125°C with proper layout - eliminating need for added heatsinking.
How does the SBR1045CTLQ's avalanche rating compare to standard rectifiers?
The SBR1045CTLQ is 100% avalanche tested to 2650W peak pulse power (1μs) and rated for 100mJ single-pulse avalanche energy - exceeding typical fast-recovery diodes (e.g., 10–50mJ) and matching high-ruggedness automotive MOSFETs. This enables reliable operation in unclamped inductive switching circuits without external snubbers in DC-DC and inverter auxiliary supplies.
