Product details
Overview
BAT54C-QVL from Nexperia is a dual common-cathode Schottky barrier diode in SOT23 package, designed for ultra-high-speed switching and reverse polarity protection in automotive electronics. It delivers 30 V reverse voltage rating, 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 - enabling low-loss signal routing in CAN/LIN bus interfaces and power rail clamping.
For engineers reviewing the BAT54C-QVL datasheet, BAT54C-QVL pinout, BAT54C-QVL application, or BAT54C-QVL equivalent, key selection criteria include AEC-Q101 qualification, dual-diode topology with shared cathode, low VF/low Cd trade-off for high-frequency line termination, and thermal resistance of 500 K/W on FR4 PCB.
Technical Context
This dual Schottky diode integrates two independent anodes (A1, A2) and a common cathode (K1/K2) in a single SOT23 footprint, supporting independent channel operation while sharing thermal and layout resources. Its planar structure with guard ring ensures robust ESD and transient stress immunity per AEC-Q101 requirements.
The device operates with junction temperatures up to 150 °C and ambient range from −55 °C to +150 °C, with pulsed forward current capability up to 600 mA (non-repetitive) and continuous 200 mA rating. Reverse recovery time of 5 ns confirms suitability for >100 MHz digital signal clamping and fast edge conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum DC or repetitive peak reverse bias before breakdown; defines safe operating margin in 24 V automotive systems. |
| Forward Voltage (VF) | 800 mV @ 100 mA - Low conduction loss enables efficient clamping and polarity protection without significant voltage drop. |
| Reverse Leakage (IR) | 2 µA @ 25 V - Minimal standby current preserves battery life in always-on vehicle modules. |
| Diode Capacitance (Cd) | 10 pF @ 1 V - Enables clean signal integrity in high-speed data lines (e.g., USB 2.0, LIN, CAN FD stubs). |
| Reverse Recovery Time (trr) | 5 ns - Supports switching frequencies beyond 100 MHz; critical for EMI suppression in SMPS feedback paths. |
| Junction Temperature (Tj) | 150 °C - Rated for under-hood environments including engine control units and body control modules. |
| Thermal Resistance (Rth(j-a)) | 500 K/W - Measured on standard FR4 PCB; informs heatsinking needs for sustained 200 mA operation. |
Pinout & Package
Encapsulated in SOT23 (TO-236AB), a 3-terminal surface-mount plastic package measuring 2.9 mm × 1.3 mm × 1.0 mm with 1.9 mm lead pitch and standard footprint for reflow/wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 (A1) | Input terminal for first Schottky diode; used independently for dual-rail clamping or redundancy. |
| 2 | Anode 2 (A2) | Input terminal for second Schottky diode; allows separate signal or power path protection. |
| 3 | Common Cathode (K1/K2) | Shared output node; simplifies PCB routing and reduces component count in dual-channel designs. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ruggedness against ESD and voltage transients - validated per AEC-Q101 stress tests. |
| Low forward voltage | 800 mV at 100 mA enables minimal insertion loss in power rail protection circuits. |
| Ultra-low capacitance | 10 pF at 1 V supports high-speed signal integrity in LIN/CAN stubs and USB D+/D− lines. |
| AEC-Q101 qualification | Qualified for automotive grade 1 (−40 °C to +125 °C ambient) and extended temperature operation. |
Applications
| Automotive LIN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
|
Use Scenario: Protecting LIN transceiver I/O pins from load dump and ESD events in door modules and seat controllers.

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 NSR20F30NXT5G | Single diode, 30 V, 200 mA, 550 mV VF @ 100 mA, 12 pF Cd | Requires two devices for dual-path use; higher VF improves efficiency but lacks integrated dual topology. | Select when discrete optimization of each path is preferred over space-constrained dual layout. |
| Vishay SMBJ30A-E3/52 | Unidirectional TVS, 30 V standoff, 48.4 V clamping, 600 W peak pulse power | Designed for surge suppression, not steady-state clamping; no low-VF conduction capability. | Choose only for ISO 7637-2 pulse 5a/b protection where Schottky conduction is unnecessary. |
Compared with NSR20F30NXT5G and SMBJ30A-E3/52, BAT54C-QVL uniquely combines dual-anode integration, sub-1 V forward drop, and 5 ns switching in one AEC-Q101-qualified SOT23 - making it optimal for compact, high-frequency automotive signal and power protection where board space and timing precision are critical.

FAQ
Is BAT54C-QVL suitable for 48 V mild-hybrid vehicle systems?
No. BAT54C-QVL has a 30 V maximum reverse voltage rating, limiting its use to 12 V and 24 V automotive subsystems. For 48 V architectures, Nexperia offers BAT54CJ-Q, rated at 40 V, or discrete alternatives like PMEG3010CEH with 40 V VR and identical SOT23 packaging.
Can BAT54C-QVL replace BAT54SW-Q in a design?
No. BAT54SW-Q is a single Schottky diode in SOT323; BAT54C-QVL is dual common-cathode in SOT23. Pinout, functionality, and package dimensions differ - direct replacement would require PCB redesign and validation of dual-path interaction effects.
What is the meaning of the marking code %W1 on BAT54C-QVL?
The marking "%W1" consists of a site code placeholder (%) followed by "W1", which identifies the specific wafer fab and assembly location. The % symbol varies by manufacturing site (e.g., 'A' for Nijmegen, 'B' for Bangkok); full traceability is maintained through Nexperia's lot tracking system.
Does BAT54C-QVL require derating above 25 °C ambient?
Yes. Total power dissipation must be derated linearly above 25 °C ambient using Rth(j-a) = 500 K/W. At 85 °C ambient, maximum continuous power drops to 125 mW (250 mW × (1 − (85−25)/500)), limiting usable forward current to ~140 mA under natural convection on standard FR4.
