Product details
Overview
B560CQ-13-F from Diodes Incorporated is a 60 V, 5.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.70 V max forward voltage at 5.0 A, 0.5 mA max reverse leakage at rated VR, and qualified to AEC-Q101 for automotive-grade reliability. It serves as a low-loss polarity protection or freewheeling diode in DC/DC converters and power supply outputs.
For engineers reviewing the B560CQ-13-F datasheet, B560CQ-13-F pinout, B560CQ-13-F application, or B560CQ-13-F equivalent, key selection criteria include its 60 V reverse blocking rating, thermal resistance of 10 °C/W (junction-to-terminal), guard ring die construction for transient immunity, and RoHS-compliant lead-free plating suitable for automated assembly.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve surge robustness under repetitive transients. Its low VF and fast switching (tRR ≤ 16 ns) minimize conduction and recovery losses in high-frequency switching topologies.
Designed for surface-mount operation on FR-4 PCBs with defined copper pad heatsinking, it delivers 5.0 A average rectified current with thermal derating above 25 °C ambient - junction temperature rated from –55 °C to +150 °C and validated per J-STD-020 moisture sensitivity Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating range in polarity protection and flyback clamp circuits. |
| IO | 5.0 A - Continuous average forward current at TA = +25°C with specified PCB heatsinking; usable up to 125°C junction with derating. |
| VF Max | 0.70 V @ 5.0 A - Peak forward voltage drop determining conduction loss and thermal load in high-current paths. |
| IR Max | 0.5 mA @ 60 V, 25°C - Reverse leakage limiting standby power loss and ensuring stable blocking in low-power hold-up applications. |
| tRR | 16 ns - Reverse recovery time enabling efficient operation in >100 kHz switching converters without significant tail current loss. |
| RθJT | 10 °C/W - Junction-to-terminal thermal resistance; enables direct thermal coupling to copper pads or heatsinks for predictable thermal management. |
| Package | SMC - Surface-mount case with 0.21 g mass, UL 94V-0 molded plastic body, and matte tin-plated terminals solderable per MIL-STD-202. |
Pinout & Package
SMC package: 2-terminal surface-mount device with cathode band marking; no internal pins - anode and cathode are exposed metal terminals on opposite ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side in rectification; must be routed with adequate copper area for 5.0 A current and thermal dissipation. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output/load ground or return path; critical for polarity protection orientation and ESD path integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche and improves ESD robustness (HBM 4000 V) without requiring external TVS in many board-level designs. |
| AEC-Q101 qualification | Validated for automotive underhood and infotainment systems where temperature cycling and long-term reliability are mandatory. |
| Lead-free & halogen-free | Meets RoHS 3 and "Green" definitions (<900 ppm Br/Cl, <1000 ppm Sb); compatible with lead-free reflow profiles and environmental compliance programs. |
| Low RθJT (10 °C/W) | Enables direct thermal transfer to PCB copper pads, supporting compact layout without discrete heatsinks in 5–10 W power stages. |
Applications
| DC/DC Converter Output Rectification | Polarity Protection in Automotive ECUs |
|---|---|
Use Scenario: Used in synchronous or asynchronous buck converter outputs delivering 3.3–12 V at up to 5 A. IC Role / Device Role / Timing Role: Freewheeling/Schottky rectifier replacing slower PN diodes to reduce conduction loss and improve efficiency. Use Value: 0.70 V VF at 5 A lowers power loss by ~30% vs. comparable 1 A Schottky, enabling higher density and cooler-running 5 W–10 W modules. |
Use Scenario: Installed inline between battery feed and microcontroller power rail in engine control units. IC Role / Device Role / Timing Role: Reverse polarity protection diode preventing damage during battery jump-start misconnection. Use Value: 60 V VRRM withstands load dump transients up to 40 V, while AEC-Q101 qualification ensures 15-year field reliability under thermal cycling. |
| Industrial Power Supply Hold-Up | LED Driver Freewheeling Path |
Use Scenario: Placed across bulk capacitor inputs in AC/DC front-ends to maintain voltage during brief AC dropout. IC Role / Device Role / Timing Role: Low-leakage blocking diode preserving stored energy with minimal self-discharge. Use Value: 0.5 mA IR max at 25°C limits standby drain, extending hold-up time by >15 ms compared to standard 1N5822 equivalents. |
Use Scenario: Integrated into constant-current LED driver flyback snubber networks driving 12–24 V strings. IC Role / Device Role / Timing Role: Fast-recovery freewheeling path for inductor current during MOSFET off-time. Use Value: 16 ns tRR minimizes voltage overshoot and EMI generation, reducing need for RC snubbers in Class B EMI-compliant lighting designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-50SQ060NTR-M3 | Same 60 V VRRM, 5.0 A IO, but VF = 0.65 V typ @ 5 A; TO-277 package (smaller footprint, lower RθJA = 40 °C/W). | Preferred where board space is constrained and lower profile is needed; less suited for high-temperature ambient (>105°C) without forced air. | Select when minimizing height or improving natural-convection cooling is prioritized over AEC-Q101 compliance. |
| ON Semiconductor SB560-E3/54 | 60 V VRRM, 5.0 A IO, VF = 0.72 V max @ 5 A; SMC package, but not AEC-Q101 qualified and IR = 1.0 mA max @ 25°C. | Suitable for commercial-grade power supplies but not automotive or industrial environments requiring extended lifetime validation. | Choose for cost-sensitive consumer applications where AEC-Q101 and tighter IR specs are not required. |
Compared with VS-50SQ060NTR-M3 and SB560-E3/54, B560CQ-13-F uniquely combines AEC-Q101 qualification, 0.5 mA IR max, and guard ring die - making it the only option among the three validated for automotive underhood use with guaranteed transient immunity and long-term thermal stability.

FAQ
What is the maximum junction temperature for continuous operation?
The B560CQ-13-F has a rated operating junction temperature range of –55 °C to +150 °C. Continuous operation at 150 °C requires strict adherence to thermal design rules: minimum 8.0 mm² copper pad per terminal, 2 oz copper thickness, and no ambient exceedance beyond derated limits per Figure 9. Exceeding these conditions risks premature parametric shift or failure.
Is this diode suitable for synchronous rectification?
No - B560CQ-13-F is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET-based solution. It functions as a unidirectional freewheeling or polarity protection device. For synchronous rectification, a dedicated gate driver IC paired with a low-RDS(on) MOSFET is required; this diode serves only as the replacement for conventional PN rectifiers in non-controlled topologies.
Does the "Q" suffix indicate automotive qualification?
Yes - the "Q" in B560CQ-13-F explicitly denotes AEC-Q101 qualification per Diodes Incorporated's part numbering convention. This is confirmed in the datasheet notes (Note 4), which state all B5X0CQ variants are PPAP-capable and AEC-Q101 qualified for high-reliability automotive applications, including underhood and infotainment systems.
Can this diode replace a 1N5822 in existing designs?
Yes, with caveats: B560CQ-13-F matches 1N5822's 3 A IO rating only at lower ambient temperatures; its 5.0 A rating assumes optimized PCB heatsinking per Note 6. At 60 V VRRM, it exceeds 1N5822's 40 V rating, offering improved transient margin. However, its SMC footprint differs from DO-201AD, requiring layout revision and thermal validation.
