Product details
Overview
BAT54S-QVL from Nexperia is a dual common-cathode Schottky barrier diode in SOT23 package, rated for 30 V reverse voltage, 800 mV forward voltage at 100 mA, and 5 ns reverse recovery time, with AEC-Q101 qualification for automotive line termination and reverse polarity protection.
For engineers reviewing the BAT54S-QVL datasheet, BAT54S-QVL pinout, BAT54S-QVL application, or BAT54S-QVL equivalent, key selection criteria include low VF for power-sensitive clamping, ultrafast trr for high-speed switching, low Cd (10 pF) for RF interface integrity, and dual-diode configuration enabling compact bidirectional protection schemes.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal (Pin 2), with Pin 1 as anode of Diode 1 and Pin 3 serving as both cathode of Diode 1 and anode of Diode 2 - forming a dual-series–common-cathode topology ideal for rail-to-rail clamping and polarity reversal circuits.
Its planar structure includes a guard ring for ESD and mechanical stress protection, and thermal design assumes FR4 PCB mounting with Rth(j-a) = 500 K/W; junction temperature must not exceed 150 °C under pulsed or continuous operation up to 200 mA average forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports 24 V automotive supply rails with 25 % margin against transients |
| Forward Voltage (VF) | 800 mV @ 100 mA - minimizes conduction loss in low-voltage signal path clamping |
| Reverse Recovery Time (trr) | 5 ns - enables reliable operation in >100 MHz digital line termination and USB data lines |
| Diode Capacitance (Cd) | 10 pF @ 1 V - preserves signal integrity in high-speed interfaces without excessive loading |
| Reverse Current (IR) | 2 µA @ 25 V - ensures low leakage in battery-backed or always-on protection circuits |
| Peak Forward Current (IFSM) | 600 mA @ 10 ms - withstands short-duration surge events like ESD-induced current spikes |
Pinout & Package
Encapsulated in SOT23 (TO-236AB) plastic package: 3-terminal surface-mount device, 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode's forward conduction path; connects to protected signal or supply rail |
| 2 | Common Cathode (K2) | Shared return path for both diodes; ties to ground or reference rail in clamp configurations |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1;A2) | Interconnect node enabling series-connected dual-diode operation or independent dual-anode use |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 |
| Guard ring integration | Enhances ruggedness against mechanical stress and localized ESD discharge in compact layouts |
| Low 10 pF capacitance | Enables use in USB 2.0, LVDS, and CAN FD signal lines without bandwidth degradation |
| 5 ns trr with 10 mA/10 mA test condition | Guarantees clean edge transitions in >100 Mbps digital bus termination applications |
Applications
| Automotive LIN Bus Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting LIN transceiver pins against load dump and battery reverse connection in vehicle body control modules. IC Role / Device Role / Timing Role: Dual-diode clamping network referenced to battery and ground, leveraging common-cathode topology for symmetric rail-to-rail voltage limiting. Use Value: Prevents transceiver damage during 30 V reverse polarity events while maintaining <1 µA standby leakage across temperature range. | Use Scenario: ESD and overvoltage protection on D+ and D− lines of embedded USB host ports in infotainment systems. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed directly at connector, with fast trr preserving 480 Mbps signal rise/fall times. Use Value: Meets IEC 61000-4-2 Level 4 (±15 kV air) without distorting eye diagram due to 10 pF Cd and 5 ns trr. |
| Industrial Sensor Signal Conditioning | DC-DC Converter Output Polarity Guard |
Use Scenario: Isolating analog sensor outputs (e.g., 4–20 mA loop receivers) from field-wiring faults in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Reverse polarity protection diode in series with signal path, using Diode 1; Diode 2 provides auxiliary clamp to AVDD. Use Value: Blocks −24 V miswiring while adding only 800 mV forward drop at full-scale current, preserving dynamic range. | Use Scenario: Preventing damage to downstream logic when a 5 V buck converter output is accidentally connected backward to a microcontroller's VDD pin. IC Role / Device Role / Timing Role: Series-connected Schottky diode (Diode 1) between converter output and load, with Diode 2 unused or configured as backup clamp. Use Value: Limits reverse current to <2 µA at −5 V, eliminating latch-up risk and enabling hot-swap capability. |
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 SOD-523; 30 V VR, 420 mV VF @ 10 mA, 1.5 pF Cd | Lacks dual-diode topology; unsuitable for common-cathode clamp or series protection | Select only when ultra-low capacitance (<2 pF) is prioritized over dual functionality |
| Vishay SMBJ24A-E3/52 | Unidirectional TVS; 24 V VBR, 600 W peak power, 100 ns response | Slower than Schottky for clamping; designed for surge, not steady-state polarity or line termination | Use only for transient-only suppression where 5 ns trr is unnecessary |
Compared with BAT54S-QVL, NSR20F30NXT5G offers lower capacitance but no dual-diode flexibility, while SMBJ24A-E3/52 delivers higher surge handling but cannot replace BAT54S-QVL in high-speed signal conditioning or reverse polarity blocking roles.

FAQ
What is the maximum continuous forward current rating for BAT54S-QVL?
The maximum continuous forward current (IF) is 200 mA at Tamb ≤ 25 °C on FR4 PCB with standard footprint. Derating applies above 25 °C ambient: linear reduction to zero at 150 °C junction temperature, governed by Rth(j-a) = 500 K/W and Ptot = 250 mW limit.
Can BAT54S-QVL be used in place of a single Schottky diode?
Yes - either diode within the BAT54S-QVL can be used independently. Pin 1–2 forms Diode 1 (A1–K2); Pin 3–2 forms Diode 2 (A2–K2). The shared cathode (Pin 2) simplifies grounding in dual-rail clamp designs but requires careful layout to avoid unintended coupling between diodes.
Is BAT54S-QVL compatible with lead-free reflow soldering profiles?
Yes - it is qualified for standard JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C for 30 seconds. The SOT23 package outline and recommended solder land pattern (Figure 6) ensure reliable wetting and void-free joints under controlled ramp rates and soak times.
How does the guard ring improve reliability in automotive environments?
The integrated guard ring mitigates edge breakdown under high electric field stress, improving resistance to humidity-induced leakage, mechanical cracking from board flexure, and localized ESD events. This contributes to AEC-Q101 compliance by enhancing robustness in temperature cycling and highly accelerated life testing (HALT) conditions.
