Product details
Overview
BAT54AW-QX from Nexperia is a dual common-anode Schottky barrier diode in SOT323 (SC-70) package, featuring 30 V reverse voltage rating, 800 mV max forward voltage at 100 mA, 2 µA max reverse current at 25 V, 10 pF capacitance at 1 V, and 5 ns reverse recovery time - optimized for ultra-high-speed switching and reverse polarity protection in automotive power rails.
For engineers reviewing the BAT54AW-QX datasheet, BAT54AW-QX pinout, BAT54AW-QX application, or BAT54AW-QX equivalent, this device supports AEC-Q101-compliant designs requiring low VF, low Cd, fast trr, and stress-protected planar construction in a 2.0 mm × 1.25 mm surface-mount footprint.
Technical Context
This dual-diode configuration integrates two independent Schottky junctions sharing a common anode terminal (Pin 3), enabling compact dual-function implementation without external interconnection. The guard ring structure enhances ESD and transient robustness per AEC-Q101 requirements.
Operation relies on majority-carrier conduction, eliminating minority-carrier storage delay - confirmed by 5 ns trr under IF = 10 mA / IR = 10 mA test conditions. Thermal resistance Rth(j-a) is 625 K/W when mounted on standard FR4 PCB with single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 30 V maximum - sets absolute upper limit for clamping or blocking applications without breakdown. |
| VF (Forward Voltage) | 800 mV max at 100 mA - enables low-loss rectification and voltage clamping in 3.3 V/5 V systems. |
| IR (Reverse Current) | 2 µA max at 25 V - ensures minimal leakage in high-impedance signal paths or battery backup circuits. |
| Cd (Capacitance) | 10 pF at 1 V, 1 MHz - supports clean high-frequency line termination up to ~1 GHz bandwidth. |
| trr (Recovery Time) | 5 ns typical - allows reliable operation in >100 MHz digital switching and data-line protection. |
| IF (Forward Current) | 200 mA continuous - sustains steady-state current in power-rail OR-ing and load-switching functions. |
| Ptot (Power Dissipation) | 200 mW at Tamb ≤ 25 °C - defines thermal derating envelope for PCB layout and ambient temperature design. |
Pinout & Package
Encapsulated in SOT323 (SC-70), a 3-pin, 2.0 mm × 1.25 mm × 0.95 mm surface-mount plastic package with 1.3 mm lead pitch and standardized reflow footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (Diode 1) | Output node for first Schottky path; connects to protected load or signal line. |
| 2 | Cathode (Diode 2) | Independent output node for second Schottky path; enables dual-rail or redundancy use. |
| 3 | Common Anode | Shared input terminal - simplifies PCB routing for dual-cathode configurations like rail clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Guard Ring Integration | Planar structure with integrated guard ring improves ESD tolerance and mechanical stress resilience per AEC-Q101. |
| Low Forward Voltage | 800 mV max at 100 mA reduces conduction loss in battery-fed and low-voltage power paths. |
| Ultra-Low Capacitance | 10 pF at 1 V minimizes signal distortion in high-speed data lines and RF interface termination. |
| AEC-Q101 Qualified | Qualified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
| Fast Reverse Recovery | 5 ns trr enables clean switching in USB, LVDS, and CAN FD bus protection circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-anode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30NXT5G | 30 V VR, 420 mV typ VF at 10 mA, SOD-523 package (1.2 mm × 0.8 mm), no AEC-Q101 qualification. | Smaller footprint but lower current rating (120 mA) and unqualified for automotive use. | Select when board space is critical and automotive qualification is not required. |
| Vishay VS-2EDH01HM3/85A | 40 V VR, 510 mV typ VF at 100 mA, SOT-323 package, AEC-Q101 qualified, higher trr (10 ns). | Higher voltage margin and same package, but slower recovery limits >50 MHz signal use. | Select when 40 V blocking is needed and 10 ns trr is acceptable for CAN or LIN bus protection. |
Compared with BAT54AW-QX, NSR20F30NXT5G saves area but sacrifices automotive compliance and current capability, while VS-2EDH01HM3/85A extends voltage range at the cost of timing performance - making BAT54AW-QX optimal for AEC-Q101 systems demanding balanced speed, leakage, and thermal robustness.

FAQ
What is the maximum junction temperature for BAT54AW-QX?
The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Operation above this temperature risks permanent degradation of the Schottky junction and guard ring integrity. Derating begins at Tamb > 25 °C per the Rth(j-a) = 625 K/W thermal resistance specification.
Can BAT54AW-QX be used in place of a single Schottky diode?
Yes - Pin 1 and Pin 3 form one diode (K1–A), and Pin 2 and Pin 3 form another (K2–A). Either path can be used independently by leaving the unused cathode floating; the common anode (Pin 3) must be connected to the positive rail or reference node.
Is the 5 ns reverse recovery time measured under standard JEDEC conditions?
Yes - trr is measured per JEDEC JESD282B using IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω, and Tamb = 25 °C. This confirms suitability for >100 MHz switching where minority-carrier delay must be avoided.
Does the "Q" suffix indicate RoHS compliance?
Yes - the "Q" suffix denotes AEC-Q101 qualification and full RoHS compliance (Pb-free, halogen-free, compliant with EU Directive 2011/65/EU and China RoHS II). Marking code "42%" includes manufacturing site identifier per Nexperia's traceability protocol.
