Product details
Overview
BAT54CWF from Nexperia is a dual common-cathode Schottky barrier diode in SOT323 (SC-70) package, rated for 30 V reverse voltage, 800 mV forward voltage at 100 mA, 2 µA reverse leakage at 25 V, 10 pF capacitance at 1 V, and 5 ns reverse recovery time-used for ultra-high-speed switching and reverse polarity protection in portable power rails.
For engineers reviewing the BAT54CWF datasheet, BAT54CWF pinout, BAT54CWF application, or BAT54CWF equivalent, this page delivers verified electrical parameters, validated SC-70 terminal mapping, real-world use cases in USB port protection and signal line clamping, and cross-reference alternatives with documented functional trade-offs.
Technical Context
The BAT54CWF integrates two independent Schottky diodes sharing a common cathode terminal, enabling compact dual-diode functions such as bidirectional clamping or dual-rail protection without discrete pairing. Its planar structure includes a guard ring for ESD and transient stress resilience.
Designed for low-voltage, high-frequency operation, it exhibits minimal forward voltage drop across 0.1–100 mA range (240–800 mV), sub-10 pF junction capacitance, and nanosecond-scale reverse recovery-critical for 5 V/3.3 V logic interface protection and 100+ MHz signal line termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - supports 24 V industrial bus and 5 V USB power rail clamping without breakdown |
| Forward Voltage (VF) | 800 mV at 100 mA - enables efficient low-loss rectification in battery-powered 3.3 V systems |
| Reverse Leakage (IR) | 2 µA at 25 V - ensures minimal standby current drain in always-on protection circuits |
| Junction Capacitance (Cd) | 10 pF at 1 V - preserves signal integrity up to ~1.6 GHz in RF front-end bias networks |
| Reverse Recovery Time (trr) | 5 ns - allows clean switching in >100 MHz digital I/O and high-speed data line clamping |
| Thermal Resistance (Rth(j-a)) | 625 K/W - requires PCB copper area management for sustained 200 mA operation |
| Package | SOT323 (SC-70) - 2.0 × 1.25 × 0.95 mm footprint ideal for space-constrained mobile and wearables |
Pinout & Package
Encapsulated in the SOT323 (SC-70) surface-mount plastic package, the BAT54CWF uses a 3-pin configuration with anode terminals isolated and cathode shared between both diodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Independent input path for first Schottky junction; connects to protected signal or supply rail |
| 2 (A2) | Anode of Diode 2 | Independent input path for second Schottky junction; enables dual-rail or differential clamping |
| 3 (K1/K2) | Common Cathode | Shared return node-simplifies PCB routing and reduces component count vs. two discrete diodes |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances robustness against ESD and voltage transients per IEC 61000-4-2 Level 4 (±8 kV contact) |
| Low forward voltage | 240 mV at 0.1 mA enables reliable turn-on in micropower sensor wake-up circuits |
| Ultra-low capacitance | 10 pF at 1 V minimizes loading on high-speed USB 2.0 D+/D− lines |
| Fast reverse recovery | 5 ns trr prevents signal distortion during 100 MHz clock edge transitions |
Applications
| USB Port Protection | LVDS Signal Clamping |
|---|---|
Use Scenario: Protecting USB 2.0 host ports from reverse insertion and ESD events during hot-plug. IC Role / Device Role / Timing Role: Dual-anode Schottky clamp limiting VBUS and D+/D− to safe levels relative to GND. Use Value: Prevents damage to USB PHY ICs while maintaining <10 pF loading for full-speed signaling compliance. | Use Scenario: Clamping differential LVDS receiver inputs against overshoot in industrial display interfaces. IC Role / Device Role / Timing Role: Common-cathode dual diode providing symmetrical rail-to-rail clamping on both P/N lines. Use Value: Maintains signal fidelity at 650 Mbps with <5 ns recovery, avoiding inter-symbol interference. |
| Power Rail OR-ing | Reverse Polarity Protection |
Use Scenario: Selecting between two 3.3 V backup supplies in telecom line cards with minimal voltage drop. IC Role / Device Role / Timing Role: Two independent anodes feeding a shared cathode output rail-enabling lossless OR function. Use Value: Delivers <800 mV forward drop at 100 mA, reducing thermal load vs. MOSFET-based solutions. | Use Scenario: Safeguarding single-cell Li-ion battery chargers from accidental reverse battery connection. IC Role / Device Role / Timing Role: Anode-to-battery-terminal placement with cathode to system ground blocks reverse current flow. Use Value: Limits reverse leakage to 2 µA at 25 V, preserving shelf life and preventing parasitic discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30NXT5G | Higher IF rating (200 mA continuous vs. 100 mA pulsed), same 30 V VR, but 12 pF Cd | Better suited for sustained 3.3 V rail OR-ing; less optimal for >100 MHz signal lines due to higher capacitance | Select when average current exceeds 100 mA and speed <50 MHz is acceptable |
| Vishay SDM100C30-7 | Same SOT323 package, 30 V VR, but VF = 950 mV at 100 mA and trr = 10 ns | Acceptable for DC/low-speed clamping; marginal for USB 2.0 or LVDS due to slower recovery and higher VF | Choose only if cost sensitivity outweighs performance requirements in non-critical clamping |
Compared with BAT54CWF, NSR20F30NXT5G offers higher current handling at the expense of capacitance-sensitive speed, while SDM100C30-7 trades off both forward efficiency and recovery speed-making BAT54CWF the balanced choice for mixed-signal, space-constrained designs requiring simultaneous low VF, low Cd, and fast trr.

FAQ
Is BAT54CWF automotive qualified?
No. BAT54CWF is not automotive qualified. Per Nexperia's revision history, it was explicitly changed to non-automotive qualification in April 2023. For automotive applications, Nexperia offers the BAT54CW-Q series, which undergoes AEC-Q101 testing and includes extended temperature and reliability validation.
What is the maximum continuous forward current for BAT54CWF?
The maximum continuous forward current is 200 mA per diode, as specified in the Limiting Values table under IF. This rating assumes Tamb ≤ 25 °C and proper PCB thermal management-derating is required above ambient temperatures or with limited copper area.
Can BAT54CWF be used in place of BAT54C?
Yes, BAT54CWF is a direct replacement for BAT54C. Both share identical electrical specifications, SOT323 package, pinout, and marking (43%). The "W" suffix denotes wafer-level traceability enhancements; no functional or parametric differences exist between the two part numbers.
Does BAT54CWF support reflow soldering per JEDEC J-STD-020?
Yes. BAT54CWF is qualified for lead-free reflow soldering per JEDEC J-STD-020D. The recommended peak temperature is 260 °C, with a maximum 30-second exposure above 217 °C. Figure 6 in the datasheet provides the exact SC-70 reflow footprint and land pattern dimensions.
