Product details
Overview
BAT54TW-7 from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, configured as two independent anode-common diodes (A1–C1 and A2–C2), with 30 V reverse voltage rating, 200 mA continuous forward current, and 240–500 mV forward voltage at 0.1–100 mA. It serves in polarity protection and signal clamping circuits for USB interfaces and low-voltage DC power rails.
For engineers reviewing the BAT54TW-7 datasheet, BAT54TW-7 pinout, BAT54TW-7 application, or BAT54TW-7 equivalent, key selection criteria include its symmetrical dual-anode-common topology, ultra-low VF at microamp bias, 5 ns reverse recovery time, and ESD-protected junction guard ring-critical for high-speed I/O and space-constrained portable designs.
Technical Context
The BAT54TW-7 integrates two discrete Schottky diodes sharing a common anode terminal pair (A1/A2) and isolated cathodes (C1/C2), enabling bidirectional clamping or dual-rail protection without cross-coupling. Its PN junction guard ring suppresses transient-induced latch-up and meets >8 kV HBM ESD immunity per IEC 61000-4-2.
Thermal performance is defined by 625 °C/W junction-to-ambient resistance on standard FR-4 PCB layout, limiting max ambient operation to +150 °C at full 200 mA load. Capacitance remains ≤10 pF at 1 V reverse bias, supporting <100 MHz signal integrity in data line applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking capability before breakdown; sets safe operating margin for 24 V systems. |
| IF Continuous | 200 mA - Sustained current per diode channel; supports USB VBUS monitoring and low-power rail clamping. |
| VF @ 10 mA | 320 mV - Low conduction loss enables efficient signal-level clamping with minimal voltage offset. |
| tRR | 5.0 ns - Fast recovery ensures minimal distortion in 10–50 MHz digital signal routing and ESD pulse handling. |
| CT @ 1 V | 10 pF - Low junction capacitance preserves signal edge rate in high-speed data lines (e.g., USB 2.0 D+/D−). |
| IR @ 25 V | 2.0 µA - Low leakage maintains accuracy in precision bias networks and high-impedance sensing nodes. |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.0 × 2.225 mm footprint, 0.9 mm height), rated UL 94V-0, moisture sensitivity level 1, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Common anode input for first Schottky path; tied to system ground or reference in clamp configurations. |
| A2 | Anode of Diode 2 | Independent anode input for second Schottky path; allows separate biasing or dual-rail protection. |
| C1 | Cathode of Diode 1 | Output node for clamped signal or protected rail; connects to I/O line or supply input. |
| C2 | Cathode of Diode 2 | Second output node; enables simultaneous protection of complementary signals (e.g., D+ and D−). |
| NC | No Connect | Pin 5 is unconnected internally; must be left floating or grounded per layout guidelines. |
| NC | No Connect | Pin 6 is unconnected internally; no electrical function; avoid routing traces to it. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical dual-anode-common configuration | Enables identical clamping behavior on two independent signal paths without shared cathode interference. |
| Junction guard ring | Prevents ESD-triggered latch-up and improves transient immunity beyond standard Schottky structures. |
| Ultra-low VF at 0.1 mA | 240 mV forward drop allows effective clamping of logic-level signals (e.g., 1.8 V/3.3 V GPIO) without false triggering. |
| Halogen- and antimony-free "Green" construction | Meets automotive and industrial environmental compliance requirements (<900 ppm Br/Cl, <1000 ppm Sb). |
Applications
| USB 2.0 Data Line Protection | Low-Voltage Rail Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD events and overvoltage transients in portable USB peripherals. IC Role / Device Role / Timing Role: Dual-channel Schottky clamp diode array providing bidirectional voltage limiting at each data line. Use Value: 5 ns tRR and ≤10 pF CT preserve signal integrity up to 480 Mbps while meeting IEC 61000-4-2 Level 4 (±15 kV air). | Use Scenario: Clamping 3.3 V or 5 V supply rails against backfeed, inrush, or hot-swap transients in embedded controllers. IC Role / Device Role / Timing Role: Independent anode-referenced diode pair isolating upstream/downstream power domains. Use Value: 200 mA IF rating and 320 mV VF at 10 mA enable low-loss, thermally stable rail isolation without external series resistors. |
| GPIO Signal Conditioning | RS-232 Level Translation Interface |
Use Scenario: Conditioning 1.8 V/3.3 V microcontroller GPIO pins exposed to external connectors or sensors. IC Role / Device Role / Timing Role: Input protection diode array limiting voltage excursions to safe levels relative to IO supply. Use Value: 240 mV VF at 0.1 mA ensures clamping activates below logic high threshold, preventing false reads during noise spikes. | Use Scenario: Translating ±12 V RS-232 signals to 3.3 V logic levels using passive diode-based level shifters. IC Role / Device Role / Timing Role: Dual Schottky path providing fast, low-drop conduction for positive/negative swing clipping. Use Value: Symmetrical A1/A2 anodes simplify bias network design; 30 V VRRM safely handles RS-232's worst-case ±15 V transients. |
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 |
|---|---|---|---|
| DMN2016LFG-7 | Single-channel, 20 V VRRM, 1.2 A IF - higher current but lower voltage rating and different topology. | Not suitable for dual-rail or differential clamping; requires two devices for BAT54TW-7 functionality. | Select only when single-diode high-current rectification is needed, not for signal-level protection. |
| BAT54CWS-7-F | Cathode-common configuration (C1/C2 shared), same VRRM/IF/tRR, identical SOT363 package. | Requires reversed PCB layout and biasing; unsuitable where anode-common topology is fixed by system grounding scheme. | Use when cathode-referenced clamping is preferred (e.g., positive rail protection with common cathode tie). |
Compared with DMN2016LFG-7 and BAT54CWS-7-F, the BAT54TW-7 uniquely provides matched dual anode-common Schottky paths in one SOT363, enabling compact, symmetric clamping without layout rework or component doubling-critical for miniaturized USB and sensor interface designs.

FAQ
What is the pin configuration of BAT54TW-7 and how are the diodes arranged?
The BAT54TW-7 uses a six-pin SOT363 package with pins A1, A2, C1, C2, NC, and NC. It contains two independent Schottky diodes: one between A1 and C1, the other between A2 and C2. Both anodes are electrically isolated, enabling separate biasing-ideal for differential signal protection like USB D+/D−.
Does BAT54TW-7 meet automotive qualification standards?
No-the BAT54TW-7 is not AEC-Q200 qualified. Diodes offers the automotive-grade BAT54TWQ variant (with Q suffix) under a separate datasheet, which includes extended temperature validation, enhanced process controls, and PPAP documentation for automotive applications.
Can BAT54TW-7 replace BAT54CWS-7-F in an existing design?
Only with layout modification: BAT54TW-7 has anode-common topology (A1/A2 inputs), while BAT54CWS-7-F is cathode-common (C1/C2 outputs). Swapping requires reversing PCB net connections and verifying bias network compatibility-no direct drop-in replacement without schematic and layout revision.
What is the maximum junction temperature and thermal derating behavior?
The BAT54TW-7 has a maximum junction temperature of +150 °C. At 25 °C ambient, it supports full 200 mA per diode; above 25 °C, current must be linearly derated at 1.6 mA/°C (per Fig.4), reaching zero at +150 °C ambient-based on standard 2 oz FR-4 PCB with specified pad layout.
