Product details
Overview
BAT54ADW-7 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 datasheet, BAT54ADW-7 pinout, BAT54ADW-7 application, or BAT54ADW-7 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 compatibility with high-speed digital interface protection in space-constrained PCB layouts.
Technical Context
The BAT54ADW-7 integrates two discrete Schottky diodes sharing a common anode terminal (Pin 1), enabling bidirectional clamping or dual-rail protection from a single footprint. Its low forward voltage minimizes conduction loss in 3.3 V and 5 V logic-level signal paths.
Designed for surface-mount assembly on FR-4 PCBs with 2 oz copper, it delivers 600 mA non-repetitive surge capability and operates across –65 °C to +150 °C ambient, supported by J-STD-020 Level 1 moisture sensitivity and matte tin-plated, solderable terminals.
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 biasing in level-shifting networks |
| VF @ 10 mA | 320 mV - Low conduction drop ensures minimal voltage offset in precision analog signal routing |
| tRR | 5.0 ns - Fast switching enables use in >100 MHz digital signal integrity applications |
| CT @ 1 V | 10 pF - Low junction capacitance preserves signal edge integrity in high-speed data lines |
| RθJA | 625 °C/W - Thermal resistance defines power derating curve on standard 2 oz FR-4 board |
| IR @ 25 V | 2.0 µA - Low leakage maintains signal fidelity in high-impedance sensing nodes |
Pinout & Package
Package: SOT363 - ultra-small 6-pin surface-mount plastic package (2.0 × 2.225 × 0.9 mm), UL 94V-0 rated, 0.006 g weight, with matte tin-plated leads compliant to MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Common Anode | Shared anode node for both diodes; connects to positive supply or reference rail |
| 2 (C1) | Cathode 1 | First diode cathode; routes protected signal or input line to ground clamp path |
| 3 (A) | Common Anode | Redundant anode connection; electrically tied to Pin 1 for mechanical stability |
| 4 (C2) | Cathode 2 | Second diode cathode; used for complementary signal path or dual-rail clamping |
| 5 (NC) | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| 6 (NC) | No Connect | Internally unconnected; no electrical function; avoid routing traces to this pad |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 240–500 mV range across 0.1–100 mA enables efficient clamping without distorting logic thresholds |
| PN junction guard ring | Integrated ESD protection structure withstands ≥2 kV HBM per AEC-Q101 requirements |
| Symmetrical configuration | No orientation indicator required; simplifies automated placement and reduces assembly error risk |
| Lead-free & Green | Fully RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb; meets automotive and industrial environmental mandates |

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 and common-anode configuration; VF = 370 mV @ 10 mA (vs. 320 mV) | Higher forward drop increases clamping threshold by ~50 mV; less suitable for 1.8 V logic interfaces | Select when tighter VF distribution control is prioritized over absolute minimum drop |
| BAT54CDW-7-F | Identical specs but common-cathode configuration (Pins 1/2 = C1/C2, Pin 3 = A); pinout incompatible | Requires PCB redesign; suited for rail-to-rail clamping where cathodes connect to separate rails | Choose only if circuit topology demands independent cathode routing and layout revision is feasible |
Compared with SBAT54DW-7-F and BAT54CDW-7-F, BAT54ADW-7 offers the lowest VF among Diodes' SOT363 dual Schottkys and unique common-anode pinout-making it optimal for ground-referenced clamping without trace rework, especially in legacy USB or RS-232 interface designs.

FAQ
What is the pin configuration of BAT54ADW-7?
BAT54ADW-7 uses a common-anode dual-diode configuration in SOT363: Pin 1 and Pin 3 are internally tied anodes, Pins 2 and 4 are independent cathodes, and Pins 5–6 are no-connect terminals. This layout enables simultaneous clamping of two signals to a shared positive rail without cross-talk.
Does BAT54ADW-7 meet automotive qualification standards?
BAT54ADW-7 itself is not AEC-Q200 qualified; however, Diodes offers the automotive-grade BAT54ADWQ variant (with Q suffix), which undergoes full AEC-Q200 stress testing and is documented in a separate datasheet (DS30152Q). Standard BAT54ADW-7 is rated for industrial temperature range (–65 °C to +150 °C) and widely used in non-safety-critical automotive subsystems.
How does the guard ring improve ESD performance?
The integrated PN junction guard ring surrounds each diode's active region to distribute electrostatic discharge current laterally, preventing localized thermal runaway. This structure enables the device to pass ≥2 kV Human Body Model (HBM) ESD tests without external protection components, verified per AEC-Q101 methodology.
Can BAT54ADW-7 replace BAT54C in the same footprint?
No-BAT54C is a single-diode SOT23 device, while BAT54ADW-7 is a dual-diode SOT363 with different pin count, spacing, and internal topology. Direct replacement would require PCB redesign. For dual-diode functionality in SOT23, consider BAT54DW (SOT323), which shares pinout compatibility with BAT54C but differs in package size and thermal performance.
