Product details
Overview
BAT54CV from Nexperia is a dual Schottky barrier diode with common cathodes in a SOT666 package, designed for ultra-high-speed switching and reverse polarity protection. It features 30 V reverse voltage rating, 200 mA forward current per diode, 800 mV forward voltage at 100 mA, 10 pF capacitance at 1 V, and operates across –65 °C to 125 °C ambient temperature.
For engineers reviewing the BAT54CV datasheet, BAT54CV pinout, BAT54CV application, or BAT54CV equivalent, key selection criteria include low VF for power-sensitive clamping, low Cd for high-frequency line termination, common-cathode dual configuration for compact bidirectional protection, and SOT666 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAT54CV integrates two independent Schottky diodes sharing a common cathode terminal (pins 1 & 2 anodes, pin 6 common cathode for D1/D2), plus a second pair (pins 4 & 5 anodes, pin 3 common cathode for D3/D4), enabling dual-channel bidirectional protection or clamping in one ultra-small package. Its planar Schottky structure with integrated guard ring ensures robust ESD and transient stress immunity.
Thermal performance is optimized for reflow-soldered FR4 PCBs: Rth(j-a) = 360 K/W (standard footprint) and 300 K/W (enhanced cathode pad), supporting continuous operation up to 125 °C junction temperature. The device is non-automotive qualified and rated for industrial and consumer applications only.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports clamping and protection in 24 V systems and USB/low-voltage data lines. |
| Forward Current (IF) | 200 mA per diode - sufficient for signal-level and low-power rail protection without derating. |
| Forward Voltage (VF) | 800 mV at 100 mA - minimizes conduction loss in high-efficiency clamping and polarity guard circuits. |
| Diode Capacitance (Cd) | 10 pF at 1 V, 1 MHz - enables use in >100 MHz signal line termination and RF interface protection. |
| Reverse Current (IR) | 2 µA at 25 V - ensures low leakage in battery-backed or always-on monitoring paths. |
| Package | SOT666 - 1.6 mm × 1.2 mm × 0.55 mm, 0.5 mm pitch, 6-pin flat lead - compatible with fine-pitch automated assembly. |
Pinout & Package
SOT666 is a 6-pin ultra-small flat-lead surface-mount plastic package with 0.5 mm pitch, 1.6 mm × 1.2 mm body size, and excellent coplanarity for reliable reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input path for first Schottky channel; connects to protected signal or supply rail. |
| 2 | Anode of Diode 2 | Independent input for second channel; enables dual-rail or differential clamping. |
| 3 | Common Cathode of Diodes 3 & 4 | Shared return node for third/fourth diode pair; used in complementary protection schemes. |
| 4 | Anode of Diode 3 | Third independent anode - expands design flexibility for multi-path protection topologies. |
| 5 | Anode of Diode 4 | Fourth anode - supports full bridge rectification or redundant polarity guard configurations. |
| 6 | Common Cathode of Diodes 1 & 2 | Primary shared cathode node; standard connection point for most dual-diode applications. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 800 mV @ 100 mA - reduces power dissipation and thermal rise in compact designs. |
| Low capacitance | 10 pF @ 1 V - preserves signal integrity in high-speed digital and RF interfaces. |
| Integrated guard ring | Enhances ESD robustness and transient surge tolerance without external components. |
| Ultra-small SOT666 package | 1.6 mm × 1.2 mm footprint - saves >40% board area vs. SO-8 or SOT-23-6 alternatives. |
Applications
| USB Data Line Protection | LVDS Receiver Clamping |
|---|---|
|
Use Scenario: Protecting USB 2.0 D+ and D− lines from ESD and overvoltage transients during hot-plug events. IC Role / Device Role / Timing Role: Bidirectional clamping diode array placed between connector and PHY IC. Use Value: 10 pF capacitance avoids signal distortion at 480 Mbps; 30 V VR withstands IEC 61000-4-2 ±15 kV contact discharge. |
Use Scenario: Limiting differential swing at LVDS receiver inputs to prevent latch-up or damage from overshoot. IC Role / Device Role / Timing Role: Low-capacitance clamp connected between differential pair and ground/VCC rails. Use Value: 800 mV VF ensures clamping threshold stays within LVDS common-mode range (0.9–1.3 V); dual configuration supports symmetrical clipping. |
| Reverse Polarity Input Guard | High-Speed Logic Level Translation |
|
Use Scenario: Preventing damage when a 3.3 V or 5 V supply is accidentally reversed during field maintenance or modular insertion. IC Role / Device Role / Timing Role: Series-connected Schottky anode-to-input, cathode-to-rail, with common-cathode configuration enabling dual-rail support. Use Value: 200 mA IF rating handles typical microcontroller or sensor module inrush; low VF adds <100 mV drop in normal operation. |
Use Scenario: Shifting logic levels between 1.8 V FPGA I/O and 3.3 V peripheral interfaces while maintaining timing integrity. IC Role / Device Role / Timing Role: Clamp-based level translator using forward-biased Schottky diodes to limit high-side excursion. Use Value: Sub-1 ns recovery time and 10 pF Cd preserve edge rates for >100 MHz clock/data signals; dual diodes allow independent translation paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30HT1G | Single dual-diode (common cathode only), SOD-523 package, 30 V VR, 200 mA IF, 370 mV VF @ 10 mA. | Limited to single common-cathode topology; no dual-common-cathode (D1/D2 + D3/D4) flexibility. | Select when board space is extreme and only one dual-diode pair is needed; not suitable for four-anode topologies. |
| Diodes Inc. BAV99W-7-F | Two diodes in common-anode SOT-363, 70 V VR, 215 mA IF, 1.25 V VF @ 50 mA, 2 pF Cd. | Common-anode architecture requires inverted layout; higher VF increases conduction loss; lower Cd benefits RF but limits clamping margin. | Prefer for higher-voltage (>30 V) or ultra-low-capacitance (<3 pF) needs; avoid where low VF or common-cathode routing is critical. |
Compared with NSR20F30HT1G and BAV99W-7-F, BAT54CV uniquely provides two independent common-cathode dual-diode pairs in one SOT666 package-enabling compact four-terminal protection, flexible rail clamping, and layout-efficient dual-path designs not possible with single-pair alternatives.

FAQ
What is the maximum junction temperature for BAT54CV?
The absolute maximum junction temperature (Tj) is 125 °C, as defined in the Absolute Maximum Ratings table. Continuous operation above this temperature risks permanent degradation. Thermal design must ensure Tj remains ≤125 °C under worst-case ambient and power dissipation conditions, using Rth(j-a) = 360 K/W for standard FR4 mounting.
Is BAT54CV automotive-qualified?
No. BAT54CV is explicitly marked as non-automotive qualified in the revision history and legal disclaimers. It has not undergone AEC-Q101 testing or qualification for automotive applications and is intended solely for industrial, consumer, and computing use cases.
Can BAT54CV be used for AC signal rectification?
It is not recommended for general-purpose AC rectification. The BAT54CV is optimized for high-speed switching, clamping, and protection-not sustained forward conduction. Its 200 mA per diode rating and pulsed test conditions indicate suitability for transient suppression, not continuous RMS current handling.
What is the meaning of the marking code 'C5' on BAT54CV?
'C5' is the manufacturer-specific top-marking code for BAT54CV in SOT666 packaging, as confirmed in Table 4 of the datasheet. It serves as a visual identification aid during inspection and assembly, and corresponds exclusively to this part number and package variant.
