Product details
Overview
BAT54VY-QX from Nexperia is a Schottky barrier triple diode in SOT363-3 (SC-88) package, rated for 30 V reverse voltage and 500 mV forward voltage at 30 mA, with 10 pF capacitance at 1 V and 1 MHz. It delivers ultra-low VF and low Cd for high-speed switching, clamping, and reverse polarity protection in automotive power management and signal line interfaces.
For engineers reviewing the BAT54VY-QX datasheet, BAT54VY-QX pinout, BAT54VY-QX application, or BAT54VY-QX equivalent, this device supports AEC-Q101-qualified designs requiring stable low-VF triple-diode integration in space-constrained PCB layouts with thermal performance up to 150 °C junction temperature.
Technical Context
This triple Schottky diode integrates three independent anode-cathode pairs in a single TSSOP6 outline, enabling compact implementation of parallel clamping or multi-rail protection without discrete placement. Each diode shares identical electrical specs: 30 V VR, 200 mA IF continuous, and 11 A IFRM peak current under defined pulse conditions.
The device uses flat-lead construction for coplanarity control and improved thermal transfer to PCB, with Rth(j-a) = 490 K/W and Rth(j-sp) = 150 K/W when soldered per recommended footprint. Its 10 pF capacitance and sub-500 mV VF at 30 mA support >100 MHz switching in USB, LVDS, and CAN bus termination circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability per diode; enables use in 24 V automotive systems with margin. |
| Forward Voltage (VF) | 500 mV @ 30 mA - Low conduction loss improves efficiency in clamping and OR-ing applications. |
| Diode Capacitance (Cd) | 10 pF @ 1 V, 1 MHz - Enables clean signal integrity in high-speed data line termination (e.g., USB 2.0). |
| Peak Forward Current (IFRM) | 900 mA @ tp ≤ 10 ms - Supports transient surge handling in ESD protection paths. |
| Junction Temperature (Tj) | 150 °C - Rated for under-hood automotive environments with sustained thermal stress. |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - Direct thermal path to solder points enables effective heat dissipation on standard FR4 PCBs. |

Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 500 mV @ 30 mA - Reduces power loss and self-heating during continuous clamping operation. |

Applications
| Automotive Body Control Module (BCM) | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting LIN bus and sensor inputs from load dump and reverse battery events in door modules and lighting controllers. IC Role / Device Role / Timing Role: Triple Schottky clamp array providing bidirectional overvoltage suppression and reverse polarity blocking per signal line. Use Value: Eliminates need for three separate diodes while maintaining 30 V standoff and <500 mV conduction drop across all protected nodes. |
Use Scenario: ESD and transient protection on D+ and D− lines of embedded USB host ports in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance clamping diode pair with third diode reserved for VBUS monitoring or auxiliary bias path. Use Value: 10 pF capacitance prevents signal degradation at 480 Mbps; AEC-Q101 rating ensures reliability in vehicle-mounted systems. |
| Industrial PLC Digital Input Stage | LVDS Receiver Termination |
Use Scenario: Input conditioning for 24 V DC digital inputs exposed to field wiring transients and miswiring. IC Role / Device Role / Timing Role: Reverse polarity protection + voltage clamping + pull-up bias path using three independent diodes. Use Value: Single-component solution replaces discrete diode-resistor network, reducing BOM count and improving layout repeatability. |
Use Scenario: AC-coupled termination of differential LVDS pairs in motor drive feedback interfaces. IC Role / Device Role / Timing Role: Dual clamping diodes (D+ and D− to common reference) plus third diode for common-mode bias stabilization. Use Value: Matches 100 Ω differential impedance while adding <10 pF parasitic loading-critical for jitter-sensitive position encoder links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky triple diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN3028LFG-7 | Single-channel 30 V N-channel MOSFET with integrated Schottky; no triple-diode topology. | Designed for load switch + reverse polarity protection-not suitable for multi-line clamping. | Select only if replacing discrete MOSFET+diode combo; not a functional substitute for BAT54VY-QX's triple-anode architecture. |
| RB050M-30 | Single Schottky diode, 30 V/1 A, SOD-123FL package; lacks triple configuration and low-Cd optimization. | Requires three devices and extra routing; 25 pF capacitance limits use above 50 MHz. | Use only in non-high-speed, cost-sensitive industrial designs where board space and signal integrity are secondary. |
Compared with DMN3028LFG-7 and RB050M-30, BAT54VY-QX uniquely provides three matched, low-capacitance Schottky junctions in one AEC-Q101-qualified package-enabling compact, high-fidelity signal line protection unattainable with single-device alternatives.

FAQ
What is the maximum continuous forward current per diode in BAT54VY-QX?
The maximum continuous forward current per diode is 200 mA when mounted on an FR4 PCB with single-sided copper and standard footprint, as specified in the Absolute Maximum Ratings table. This rating assumes one diode is loaded at a time; derating applies if multiple diodes conduct simultaneously due to thermal coupling.
Does BAT54VY-QX support wave soldering?
Yes, BAT54VY-QX is qualified for both reflow and wave soldering. The official Nexperia package drawing (Fig. 6) provides a dedicated wave soldering footprint with 5.3 mm transport direction length and 1.3 mm pad width, optimized for consistent wetting and void-free joints on standard TSSOP6 land patterns.
How does the flat-lead design improve thermal performance?
The flat-lead construction reduces thermal resistance from junction to solder point (Rth(j-sp) = 150 K/W) by maximizing metal-to-PCB contact area and minimizing interfacial voids. This enhances heat transfer during pulsed operation and improves long-term reliability in thermally demanding automotive environments.
Can BAT54VY-QX be used in 48 V mild-hybrid automotive systems?
No-BAT54VY-QX has a 30 V reverse voltage rating, making it unsuitable for direct use in 48 V system rails. It is rated for 12 V/24 V automotive subsystems such as infotainment, body electronics, and sensor interfaces where transient clamping occurs below 30 V.
