Product details
Overview
BAT54ADW-7-F from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, configured as two independent anode-common (common-anode) diodes with 30 V reverse voltage rating, 200 mA continuous forward current, and ultra-low 240–500 mV forward voltage at 0.1–100 mA. It serves in polarity protection and signal clamping circuits for USB data lines and low-voltage I/O interfaces.
For engineers reviewing the BAT54ADW-7-F datasheet, BAT54ADW-7-F pinout, BAT54ADW-7-F application, or BAT54ADW-7-F equivalent, key selection criteria include common-anode dual-diode topology, 5 ns reverse recovery time, 10 pF junction capacitance at 1 V, thermal resistance of 625 °C/W, and RoHS-compliant matte tin-plated terminals suitable for high-density PCB layouts.
Technical Context
This device integrates two discrete Schottky diodes sharing a common anode terminal (Pin 1), enabling bidirectional clamping or dual-path rectification in compact space-constrained designs. Its guard-ringed PN junction provides ESD robustness up to ±8 kV HBM and transient immunity without external protection components.
The SOT363 package supports reflow soldering per J-STD-020 Level 1 moisture sensitivity, with 0.006 g mass and 2.0 mm × 2.225 mm footprint. Thermal performance is defined on 1-layer FR-4 board with 2 oz copper, delivering 200 mW power dissipation under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit for 24 V rail clamping. |
| IF | 200 mA - Continuous forward current per diode; supports sustained signal-level rectification or biasing. |
| tRR | 5.0 ns - Reverse recovery time at IF = 10 mA; enables operation in >100 MHz digital signal paths. |
| CT | 10 pF at VR = 1 V - Junction capacitance; minimizes loading on high-speed data lines like USB 2.0. |
| RθJA | 625 °C/W - Junction-to-ambient thermal resistance; requires minimal copper area for thermal management. |
| VF | 240–500 mV - Forward voltage range across 0.1–100 mA; reduces conduction loss in low-voltage logic interfaces. |
| IR | 2.0 µA at VR = 25 V - Reverse leakage; ensures negligible standby current in battery-powered systems. |
Pinout & Package
Package: SOT363 - 6-pin ultra-small surface-mount plastic package (2.0 mm × 2.225 mm × 0.9 mm height), UL 94V-0 rated, lead-free and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Common Anode | Shared anode connection for both diodes; ties to positive supply or reference node. |
| 2 | Cathode 1 | Output cathode of first Schottky diode; used for clamping or rectification path A. |
| 3 | No Connect | Internally unconnected; must be left floating or tied to ground only if required by layout rules. |
| 4 | Cathode 2 | Output cathode of second Schottky diode; enables independent clamping path B. |
| 5 | No Connect | Internally unconnected; no electrical function; avoid routing signals to this pad. |
| 6 | Common Anode | Redundant anode terminal (same net as Pin 1); improves current sharing and thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Common-anode dual configuration | Enables symmetrical bidirectional clamping on differential pairs without extra traces or components. |
| Guard-ringed junction | Provides inherent ESD protection (±8 kV HBM) and surge resilience without external TVS devices. |
| Ultra-low VF at low current | 240 mV at 0.1 mA allows reliable turn-on in micropower sensor biasing and wake-up detection circuits. |
| 5 ns tRR | Supports clean switching in high-frequency clock distribution and RF detector applications up to 200 MHz. |
| SOT363 footprint | Reduces board area by 60% vs. SO-8 equivalents while maintaining full thermal and electrical performance. |
Applications
| USB 2.0 Data Line Protection | Low-Voltage Logic-Level Shifting |
|---|---|

IC Role / Device Role / Timing Role: Dual-path polarity guard ensuring sensor ICs remain powered regardless of input polarity reversal. Use Value: 30 V VRRM withstands induced transients; 200 mA IF supports multiple parallel sensors. | Use Scenario: Combining two independent 5 V power sources (e.g., main + backup) with automatic failover. IC Role / Device Role / Timing Role: Common-anode OR-ing diode pair preventing backfeed between supplies during switchover. Use Value: Low 500 mV VF at 100 mA limits voltage drop and heat generation versus MOSFET solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Same SOT363 package, identical common-anode topology, but rated for 40 V VRRM and 300 mA IF. | Higher reverse voltage margin suits 36 V industrial buses; higher IF supports heavier load switching. | Select when system transients exceed 30 V or average current exceeds 200 mA per diode. |
| BAT54CWS-7-F | Common-cathode configuration (Pins 1/2 = cathodes, Pin 3 = common anode), same electrical specs. | Requires inverted PCB layout; suited for cathode-referenced clamping or rail-to-rail signal steering. | Choose only when circuit topology mandates common-cathode arrangement-pinout is not interchangeable. |
Compared with BAT54ADW-7-F, SBAT54DW-7-F offers higher voltage headroom and current capacity at identical footprint, while BAT54CWS-7-F delivers functional equivalence only in cathode-common designs-neither is pin-compatible, requiring schematic and layout revision.

FAQ
What is the pin configuration of BAT54ADW-7-F?
BAT54ADW-7-F uses a common-anode dual-diode configuration in SOT363: Pin 1 and Pin 6 are internally connected anodes; Pin 2 and Pin 4 are independent cathodes; Pins 3 and 5 are no-connect terminals. This layout is confirmed in Diodes' DS30152 Rev. 21–2, page 1 (top view diagram).
Is BAT54ADW-7-F suitable for automotive applications?
No-BAT54ADW-7-F is not AEC-Q200 qualified. Diodes offers the automotive-grade variant BAT54SDWQ-7-F (with Q suffix), which meets AEC-Q200 Grade 1 requirements (−40°C to +125°C) and includes enhanced process controls and lot traceability.
How does the guard ring improve reliability?
The integrated PN junction guard ring suppresses edge breakdown under high dv/dt transients and increases ESD withstand capability to ±8 kV HBM. It eliminates need for external TVS diodes in I/O protection schemes, reducing BOM count and PCB area per Diodes' application note AN-4001.
Can BAT54ADW-7-F replace BAT54CWS-7-F without redesign?
No-BAT54CWS-7-F has common-cathode topology (cathodes on Pins 1/2, anode on Pin 3), whereas BAT54ADW-7-F is common-anode (anodes on Pins 1/6, cathodes on Pins 2/4). Swapping them requires schematic changes and PCB layout revision due to incompatible pin functions.
