Product details
Overview
BAT54CDW-7 from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode array in SOT363 package, configured as a common-cathode pair with 30 V reverse voltage rating, 200 mA continuous forward current per diode, and typical forward voltage of 320 mV at 1 mA. It serves as a low-loss signal clamping or polarity protection device in USB data line conditioning and low-voltage DC-DC converter output rectification.
For engineers reviewing the BAT54CDW-7 datasheet, BAT54CDW-7 pinout, BAT54CDW-7 application, or BAT54CDW-7 equivalent, key selection criteria include its symmetrical dual-diode configuration, ultra-low VF at microamp-level bias, sub-5 ns reverse recovery time, and compatibility with high-density PCB layouts requiring minimal thermal footprint.
Technical Context
The BAT54CDW-7 integrates two independent Schottky diodes sharing a common cathode terminal, 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 without external protection.
Designed for operation from –65 °C to +150 °C, it maintains stable forward conduction down to –40 °C and exhibits <10 pF total capacitance at 1 V reverse bias-critical for preserving signal integrity in 10–100 MHz RF detector and high-speed logic interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - supports 24 V rail clamping and 5 V logic-level signal routing without breakdown |
| IF (continuous) | 200 mA per diode - sufficient for USB 2.0 VBUS overvoltage protection and low-power sensor supply path switching |
| VF @ 1 mA | 320 mV typical - enables efficient signal-level clamping with <100 µA leakage-induced offset error |
| tRR | 5.0 ns max - preserves edge fidelity in 20+ MHz clock distribution and pulse-width modulation feedback paths |
| CT @ 1 V | 10 pF max - minimizes capacitive loading on high-impedance analog inputs and RF antenna switch control lines |
| RθJA | 625 °C/W - requires no thermal pad for ≤100 mW dissipation in standard FR-4 layouts |
Pinout & Package
Package: SOT363 - ultra-small 6-pin surface-mount plastic package (2.0 × 2.225 mm), moisture sensitivity level 1, matte tin-plated leads, weight ≈ 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first Schottky path; connects to signal source or power rail needing clamping |
| 2 (A2) | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-rail or differential clamping |
| 3 (C1) | Cathode (common) | Shared return path; ties both diodes to reference potential (e.g., VCC or GND) |
| 4 (C2) | Cathode (common) | Redundant cathode terminal for improved solder joint reliability and lower parasitic inductance |
| 5 (A1) | Anode of Diode 1 | Same as Pin 1 - symmetrical layout allows either end as primary anode connection |
| 6 (A2) | Anode of Diode 2 | Same as Pin 2 - symmetrical layout ensures consistent routing in automated placement |
Key Features
| Feature | Design Value |
|---|---|
| Common-cathode dual Schottky configuration | Enables single-point grounding for noise-sensitive analog front-ends while maintaining independent anode routing |
| Guard-ringed PN junction | Provides inherent ±8 kV HBM ESD immunity without adding discrete TVS devices or layout area |
| Low VF at 0.1 mA | Delivers 240 mV typical forward drop - critical for accurate biasing in precision op-amp clamp circuits |
| Symmetrical marking & pinout | Eliminates orientation dependency during pick-and-place; reduces assembly programming errors |
Applications
| USB 2.0 Data Line Protection | Low-Voltage DC-DC Output Rectification |
|---|---|
Use Scenario: Protecting D+ and D− lines against ESD events and overvoltage transients during hot-plug insertion. IC Role / Device Role / Timing Role: Dual Schottky clamp diode array providing bidirectional current steering to VBUS and GND rails. Use Value: Prevents damage to USB PHY transceivers by limiting transient voltage to <3.6 V while adding <10 pF load per line. | Use Scenario: Rectifying synchronous buck converter output where low conduction loss is essential below 1 A load. IC Role / Device Role / Timing Role: Secondary-side freewheeling diode replacing MOSFET body diode in cost-sensitive non-synchronous designs. Use Value: Reduces conduction loss by 40% vs. standard silicon diode at 100 mA, improving efficiency by 1.2% at light load. |
| RF Detector Input Clamping | Logic-Level Signal Translation |
Use Scenario: Limiting RF envelope detector input to prevent saturation of logarithmic amplifier stages. IC Role / Device Role / Timing Role: Fast-recovery Schottky clamp protecting high-impedance detector node from RF-induced DC offset drift. Use Value: Maintains detector linearity across –40 °C to +85 °C with <0.5 dB gain error due to VF temperature coefficient. | Use Scenario: Translating 3.3 V logic signals to 1.8 V I/O domains in FPGA configuration interfaces.

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 |
|---|---|---|---|
| SBAT54CDW-7-F | Same electrical specs; enhanced automotive qualification (AEC-Q101) and tighter VF binning (±10 mV) | Required for under-hood automotive modules; unnecessary for industrial or consumer PCBs | Select only if AEC-Q101 compliance or production lot consistency is mandated |
| NSR20F30NXT5G | Single-diode SOD-523 package; 30 V VRRM, 200 mA IF, but no common-cathode pairing | Requires two separate placements for dual-path use; increases board area by 45% | Choose when layout permits discrete placement and thermal isolation between diodes is preferred |
Compared with SBAT54CDW-7-F and NSR20F30NXT5G, BAT54CDW-7 offers optimal balance of integration density, ESD resilience, and cost for non-automotive high-frequency signal conditioning-avoiding both automotive overhead and discrete placement penalties.

FAQ
What is the maximum operating temperature for BAT54CDW-7?
The BAT54CDW-7 is rated for junction and storage temperatures from –65 °C to +150 °C. At ambient temperatures above 125 °C, derating begins at 0.25 mA/°C beyond 25 °C ambient, per Figure 4 in DS30152 Rev. 21–2. Thermal resistance is 625 °C/W on standard FR-4, so 100 mW dissipation yields +62.5 °C rise above ambient.
Is BAT54CDW-7 RoHS and halogen-free compliant?
Yes. BAT54CDW-7 is fully RoHS 3 compliant (2015/863/EU), lead-free, and halogen- and antimony-free per Diodes' "Green" definition: <900 ppm bromine, <900 ppm chlorine (<1500 ppm total Br + Cl), and <1000 ppm antimony compounds. This is verified in Note 3 of DS30152.
How does the symmetrical pinout affect PCB layout?
The symmetrical SOT363 pinout (A1/A2/C1/C2/C1/C2) eliminates orientation dependency: either end can serve as the primary anode side. This simplifies automated optical inspection and reduces placement programming errors, especially in dense layouts where rotation constraints would otherwise require custom land patterns.
Can BAT54CDW-7 replace BAT54CWS in the same footprint?
No. BAT54CWS uses SOT323 (SC-70) package with different pin mapping (anode-cathode-anode) and smaller 2.0 × 2.1 mm outline. BAT54CDW-7's SOT363 has 2.0 × 2.225 mm body and six pins with common-cathode symmetry-requiring distinct pad layout and stencil design per Diodes' recommended SOT363 footprint.
