Product details
Overview
BAT54DW-7-F from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode in SOT363 package, featuring 30 V peak reverse voltage, 200 mA continuous forward current per anode, and ultra-low 240–500 mV forward voltage at 0.1–100 mA. It integrates PN junction guard ring for ESD/transient protection and targets high-speed signal clamping and polarity protection in portable power management circuits.
For engineers reviewing the BAT54DW-7-F datasheet, BAT54DW-7-F pinout, BAT54DW-7-F application, or BAT54DW-7-F equivalent, key selection criteria include dual-anode common-cathode topology, 5 ns reverse recovery time, 10 pF junction capacitance at 1 V, thermal resistance of 625°C/W, and AEC-Q101 readiness for automotive-grade designs.
Technical Context
This dual Schottky diode implements two independent anode-to-cathode junctions sharing a common cathode terminal (A1–C1 and A2–C2), enabling compact dual-path rectification or steering in space-constrained layouts. Its low VF and fast tRR support efficient DC-DC feedback sensing and USB/USB-C port protection.
The SOT363 package provides six terminals with two NC pins, allowing flexible PCB routing while maintaining thermal performance up to +125°C ambient. Guard-ring-protected junctions ensure robustness against 2.0 µA leakage at 25 V reverse bias and transient overvoltage events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking capability per diode channel |
| IF (continuous) | 200 mA - Sustained forward current per anode without derating at 25°C ambient |
| VF @ 10 mA | 320 mV - Low conduction loss enabling high-efficiency signal-level clamping |
| tRR | 5.0 ns - Enables operation in >100 MHz switching applications such as RF detector biasing |
| CT @ 1 V | 10 pF - Minimal capacitive loading on high-speed data lines like I²C or UART |
| IR @ 25 V | 2.0 µA - Ensures low standby leakage in battery-backed systems |
| RθJA | 625 °C/W - Thermal limit defines maximum power dissipation on standard FR-4 PCB |
Pinout & Package
Package: SOT363 - ultra-small 6-pin surface-mount plastic package (2.0 × 2.225 × 0.9 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | First Schottky diode anode; connects to input/source side of first channel |
| C1 | Cathode 1 | First diode cathode; internally tied to C2 for common-cathode configuration |
| NC | No Connect | Unbonded terminal; must be left floating or grounded per layout best practice |
| NC | No Connect | Unbonded terminal; no internal connection; avoid solder bridging |
| C2 | Cathode 2 | Second diode cathode; internally tied to C1 - forms shared cathode node |
| A2 | Anode 2 | Second Schottky diode anode; enables independent second channel path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Same SOT363 footprint and electrical specs, but qualified to AEC-Q101 Grade 1 (-40°C to +125°C) with PPAP support | Required for automotive body control modules and infotainment power rails | Select when automotive qualification and change control documentation are mandatory |
| BAT54CDW-7-F | Identical package and pinout, but dual common-anode configuration (C1–A1, C2–A2) instead of common-cathode | Suitable for active-low enable paths or inverted logic clamping where cathode referencing is impractical | Choose only when circuit topology requires common-anode rather than common-cathode architecture |
Compared with SBAT54DW-7-F, the BAT54DW-7-F lacks formal AEC-Q101 certification but offers identical performance for commercial/industrial use; versus BAT54CDW-7-F, it provides complementary topology for cathode-referenced biasing and clamping schemes.

FAQ
What is the thermal derating behavior of BAT54DW-7-F above 25°C ambient?
Power dissipation must be linearly reduced above 25°C ambient at 0.32 mW/°C, reaching zero at +125°C. This is derived from its 625°C/W thermal resistance and 200 mW absolute maximum PD rating. Derating follows the curve in Figure 4 of DS30107 Rev. 12–2, requiring PCB copper area optimization for sustained >100 mA operation in enclosed environments.
Can BAT54DW-7-F be used in place of a single BAT54S in a design?
No - BAT54DW-7-F contains two independent Schottky diodes in common-cathode configuration (A1–C, A2–C), whereas BAT54S is a single-diode SOT23 device. Substitution would require PCB redesign to accommodate SOT363's 6-pin layout and verify that dual-channel functionality aligns with circuit intent, such as simultaneous clamping of two signals.
Is the NC pin electrically isolated or internally bonded?
Both NC pins in the SOT363 package are unconnected to any die structure - they are mechanically present for package symmetry and handling but have no internal bond wire or silicon connection. They must remain unconnected in layout; grounding or routing them may cause mechanical stress or solder wicking issues without functional benefit.
Does BAT54DW-7-F support reflow soldering per J-STD-020?
Yes - it is rated for moisture sensitivity level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/85% RH and subjected to standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C) without baking. The matte tin plating ensures compatibility with both SnPb and lead-free solder pastes per MIL-STD-202 Method 208.
