Product details
Overview
DFLS160Q from Diodes Incorporated is a 1.0A, 60V surface-mount Schottky barrier rectifier in PowerDI123 package, featuring 0.50V max forward voltage at 1.0A and 0.1mA max reverse leakage at 60V. It delivers high surge current capability (50A IFSM), AEC-Q101 qualification, and is engineered for automotive polarity protection, recirculation, and switching applications.
For engineers reviewing the DFLS160Q datasheet, DFLS160Q pinout, DFLS160Q application, or DFLS160Q equivalent, key selection criteria include its low VF for thermal efficiency, guard ring die for transient robustness, RoHS- and halogen-free "Green" construction, and IATF 16949-certified manufacturing with PPAP support.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve ESD robustness (HBM 4000V), enabling reliable operation in noisy automotive environments. Its interlocking clip design enhances mechanical bond strength and thermal path integrity to the cathode tab.
Thermal performance is optimized for PCB-mounted operation: RθJS = 6°C/W (junction-to-solder point) and RθJA = 60°C/W on a 50.8mm × 50.8mm GETEK board - critical for sustained 1.0A DC conduction at elevated ambient temperatures up to +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (VRRM) | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 12V/24V automotive systems with load dump transients. |
| IF(AV) | 1.0 A - Average forward rectified current; supports continuous power delivery in compact DC/DC input stages or LED driver return paths. |
| VF MAX | 0.50 V @ 1.0A - Low forward drop minimizes conduction loss and self-heating, enabling higher efficiency in space-constrained layouts. |
| IR MAX | 0.1 mA @ 60V - Ultra-low leakage preserves battery standby life in always-on vehicle modules (e.g., CAN wake-up circuits). |
| tRR | 12 ns - Fast reverse recovery enables use in high-frequency switching topologies (e.g., synchronous rectification auxiliary windings). |
| IFSM | 50 A @ 8.3ms - High surge rating withstands motor commutation spikes and alternator load dump events without degradation. |
| RθJS | 6 °C/W - Low junction-to-solder thermal resistance ensures efficient heat transfer directly into PCB copper, reducing need for thermal vias. |
Pinout & Package
Package: PowerDI123 - surface-mount, single-diode configuration with exposed cathode tab for thermal and electrical connection. Molded green compound (UL 94V-0), moisture sensitivity level 1, matte tin–annealed copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to positive rail or switch node; requires minimum 1.8mm × 1.2mm copper pad per datasheet layout guidance. |
| Cathode | Forward current exit / thermal path | Exposed metal tab serves as primary thermal sink and circuit return; must be soldered to ≥25.4mm² copper area for rated RθJA = 60°C/W. |
| Cathode Band | Polarity indicator | Visible marking on top surface confirms cathode orientation; essential for automated optical inspection (AOI) and manual assembly verification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche and improves ESD immunity (HBM 4000V), enhancing reliability in unregulated automotive power rails. |
| Interlocking clip design | Increases mechanical bond strength between die and leadframe, raising IFSM tolerance and long-term thermal cycling endurance. |
| AEC-Q101 qualification | Validated for automotive-grade temperature cycling (-55°C to +150°C), humidity storage, and accelerated life testing per stress test standard. |
| Halogen- and antimony-free "Green" | Meets <900ppm Br, <900ppm Cl, <1000ppm Sb; supports OEM environmental compliance and end-of-life recycling requirements. |
| PPAP-capable manufacturing | Produced in IATF 16949-certified facilities with full traceability, change control, and process validation documentation available upon request. |
Applications
| Automotive Polarity Protection | DC/DC Converter Recirculation |
|---|---|

IC Role / Device Role / Timing Role: Recirculating diode providing low-loss current path during MOSFET off-time to sustain inductor current continuity. Use Value: 12ns tRR and low CT (67pF) reduce switching losses and EMI generation, improving converter stability at >200kHz switching frequencies. |
| LED Lighting Return Path | Start-Stop System Diode Clamp |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-E3/54 | Same 60V/1.0A rating but TO-277 package; VF = 0.72V @ 1.0A; no AEC-Q101 qualification. | Lacks automotive qualification and lower thermal performance (RθJA ≈ 100°C/W); suitable only for industrial/commercial non-automotive use. | Select only if cost is primary constraint and automotive compliance is not required. |
| SS16HE3_A/H | PowerDI123 package, AEC-Q101 qualified, but VF = 0.55V @ 1.0A and IR = 0.5mA @ 60V. | Higher leakage reduces suitability for ultra-low-power sleep-mode circuits; otherwise functionally interchangeable in most 12V systems. | Prefer when slightly higher VF is acceptable and broader distributor availability is needed. |
Compared with SB160-E3/54 and SS16HE3_A/H, the DFLS160Q offers the lowest VF (0.50V), tightest IR (0.1mA), and verified PPAP support - making it the optimal choice for AEC-Q101–mandated designs where thermal efficiency and leakage-critical operation are prioritized.

FAQ
What is the maximum junction temperature for continuous operation?
The DFLS160Q has an operating junction temperature range of –55°C to +150°C. For continuous 1.0A DC operation at TA = +85°C, thermal design must ensure junction temperature remains ≤150°C using the specified RθJA = 60°C/W on a 50.8mm × 50.8mm GETEK board with proper copper layout.
Is the PowerDI123 package compatible with standard reflow profiles?
Yes - the PowerDI123 package is rated for moisture sensitivity level 1 (MSL-1) and supports JEDEC J-STD-020-compliant lead-free reflow profiles. Peak temperature must not exceed 260°C, and time above 217°C should be limited to 60–150 seconds per IPC/JEDEC standards.
Does the DFLS160Q support bidirectional current flow?
No - the DFLS160Q is a unidirectional Schottky rectifier. It conducts current only from anode to cathode and blocks reverse current up to 60V. Bidirectional operation would require a dual-diode configuration or external circuitry such as back-to-back MOSFETs.
How does the guard ring die construction improve reliability?
The guard ring physically isolates the active PN junction periphery from surface defects and contamination, suppressing premature edge breakdown during high-voltage transients. This extends device lifetime under repetitive load dump conditions (ISO 7637-2 Pulse 5a) and improves HBM ESD robustness to 4000V.
