Product details
Overview
BAT54DW-7 from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode in SOT363 package, featuring 30 V peak reverse voltage, ≤400 mV forward voltage at 10 mA, and 5 ns reverse recovery time. It integrates two independent anode-cathode pairs with PN junction guard rings for ESD/transient protection, used in polarity protection and signal clamping circuits in portable power management.
For engineers reviewing the BAT54DW-7 datasheet, BAT54DW-7 pinout, BAT54DW-7 application, or BAT54DW-7 equivalent, key selection considerations include low VF at low current (240 mV @ 0.1 mA), ultra-small footprint (SOT363), dual-diode integration for space-constrained DC-DC bias networks, and AEC-Q200 readiness via IATF 16949 manufacturing.
Technical Context
The BAT54DW-7 implements two independent Schottky diodes sharing a common cathode configuration per channel (A1–C1 and A2–C2), with no internal connection between channels. Its guard-ringed PN junction suppresses ESD events up to ±8 kV HBM while maintaining fast switching (tRR = 5 ns) and low capacitance (CT = 10 pF @ 1 V).
Thermal performance is defined for FR-4 PCB mounting (1″ × 0.85″ × 0.062″), delivering 200 mW power dissipation and 625°C/W junction-to-ambient thermal resistance. Operating temperature range spans –65°C to +125°C, supporting industrial and automotive ambient environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage before breakdown; sets upper limit for input rail clamping in 24 V systems. |
| VF @ 10 mA | ≤400 mV - Low conduction loss enables efficient voltage translation in logic-level signal routing. |
| tRR | 5 ns - Enables use in >100 MHz signal clamping and high-frequency flyback snubbing. |
| CT @ 1 V | 10 pF - Minimal parasitic capacitance preserves signal integrity in RF detector and high-speed data line protection. |
| IO | 100 mA - Continuous rectified current rating supports dual-path bias supply for op-amp input stages. |
| IR @ 25 V | ≤2.0 μA - Low leakage maintains accuracy in precision reference voltage divider networks. |
Pinout & Package
Package: SOT363 - ultra-compact 6-pin plastic surface-mount package (2.0 mm × 2.225 mm × 0.9 mm), moisture sensitivity level 1, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first Schottky path; connects to positive rail or signal source requiring polarity control. |
| C1 | Cathode of Diode 1 | Output node for Diode 1; tied to ground or reference in clamp/protect configurations. |
| NC | No Connection | Internally unconnected pin; must remain floating-no PCB trace or soldering allowed. |
| NC | No Connection | Second unused pin; electrically isolated from die and package substrate. |
| C2 | Cathode of Diode 2 | Shared cathode terminal with C1 in some variants-but datasheet confirms independent cathodes; verify layout against top-view schematic. |
| A2 | Anode of Diode 2 | Independent second anode; enables dual-rail clamping or redundant protection paths on separate nets. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at microamp currents | 240 mV @ 0.1 mA enables accurate biasing in low-power sensor front-ends without loading. |
| Guard-ringed PN junction | ESD robustness to ±8 kV HBM meets IEC 61000-4-2 Level 4 for industrial interface protection. |
| Dual independent diodes | Two isolated Schottky paths in one SOT363 footprint reduce board area by 40% vs. discrete SOD-323 pair. |
| Halogen- and antimony-free "Green" | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb compounds-complies with strict environmental mandates for automotive Tier-1 supply chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T2R | Single-channel SOD-523; 30 V VRRM, 300 mV VF @ 10 mA, 1.5 pF CT | Lower capacitance but no dual integration; requires two placements for same function | Select when ultra-low CT dominates over board area savings |
| NSR20F30NXT5G | Dual SOT-23; 30 V VRRM, 370 mV VF @ 10 mA, 12 pF CT, higher IF = 200 mA | Larger footprint than SOT363; rated for higher continuous current | Select when 200 mA IO is required and SOT-23 layout is already established |
Compared with RB520S-30T2R and NSR20F30NXT5G, BAT54DW-7 uniquely balances dual-diode integration, ultra-small SOT363 size, and guard-ring ESD protection-making it optimal for space-constrained, high-reliability portable and automotive subsystems where layout density and transient immunity are jointly critical.

FAQ
What is the pin configuration of BAT54DW-7 and how are the diodes arranged?
The BAT54DW-7 uses a 6-pin SOT363 package with pinout A1–C1–NC–NC–C2–A2 (top view). It contains two independent Schottky diodes: Diode 1 (A1→C1) and Diode 2 (A2→C2). Pins 3 and 4 are unconnected; no internal tie exists between cathodes or anodes. This arrangement enables fully isolated dual-path operation.
Does BAT54DW-7 meet automotive qualification standards?
The BAT54DW-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 out-of-box, Diodes offers AEC-Q101-compliant versions (e.g., BAT54DWQ-7-F) with full stress test reports. Standard BAT54DW-7 is widely used in automotive infotainment and body electronics where customer-specific qualification is performed.
How does the guard ring affect ESD performance and reliability?
The integrated PN junction guard ring surrounds each Schottky anode, providing a controlled path for ESD current that prevents localized thermal runaway. This structure achieves ±8 kV HBM ESD rating without external TVS components and improves long-term reliability under repeated transient stress in industrial interfaces.
Can BAT54DW-7 replace BAT54C in existing designs?
No-BAT54C is a common-cathode dual Schottky in SOT-23 package (pins: A1–A2–C), whereas BAT54DW-7 has independent cathodes and SOT363 pinout. Direct replacement requires PCB redesign due to different pin count, spacing, and internal topology. Use only if layout and schematic are updated to match A1/C1/A2/C2 isolation.
