Product details
Overview
BAT54SDWQ-7-F from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, rated for 30 V reverse voltage, 200 mA continuous forward current, and 240–500 mV forward voltage at 0.1–100 mA. It features ultra-low VF, 5 ns reverse recovery time, and PN junction guard ring for ESD/transient protection-used in automotive power rail clamping and USB port protection circuits.
For engineers reviewing the BAT54SDWQ-7-F datasheet, BAT54SDWQ-7-F pinout, BAT54SDWQ-7-F application, or BAT54SDWQ-7-F equivalent, key selection criteria include low forward voltage at low currents (240 mV @ 0.1 mA), sub-10 pF capacitance at 1 V reverse bias, AEC-Q101 qualification, IATF16949 manufacturing, and symmetrical dual-diode configuration with no orientation indicator.
Technical Context
This dual Schottky array integrates two independent anode-cathode junctions in a single SOT363 package with symmetrical terminal assignment (no polarity marking). Each diode exhibits low conduction loss due to metal-semiconductor contact and fast switching enabled by minority-carrier-free operation.
It delivers 2.0 µA max reverse leakage at 25 V, 10 pF typical junction capacitance at 1 V, and thermal resistance of 625 °C/W on standard FR-4 PCB layout-enabling compact, thermally constrained designs in automotive infotainment and body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - supports 24 V automotive supply rail clamping without breakdown |
| IF (continuous) | 200 mA - sufficient for signal-level ESD protection and logic-level clamping |
| VF @ 10 mA | 320 mV - minimizes voltage drop in low-power bias and sensing paths |
| tRR | 5.0 ns - enables high-speed signal line protection up to ~70 MHz edge rates |
| IR @ 25 V | 2.0 µA - ensures low standby current in always-on automotive subsystems |
| CT @ 1 V | 10 pF - preserves signal integrity in USB 2.0 and CAN FD data lines |
| RθJA | 625 °C/W - requires minimal copper area for thermal management in space-constrained layouts |
Pinout & Package
Package: SOT363 - ultra-small surface-mount plastic package (2.15 × 2.10 × 0.95 mm), moisture sensitivity level 1, lead-free matte tin plating, weight 0.006 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first Schottky path; connects to protected signal or supply rail |
| A2 | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-rail or dual-signal protection |
| C1 | Cathode of Diode 1 | Common return to ground or reference rail; shared cathode topology not used here |
| C2 | Cathode of Diode 2 | Independent cathode node; allows separate clamping thresholds per channel |
| A3 | No internal connection | Unused terminal; must be left floating or tied to ground only if required by layout |
| C3 | No internal connection | Unused terminal; electrically isolated; no functional role in circuit operation |
Key Features
| Feature | Design Value |
|---|---|
| Low-forward voltage drop | 240 mV @ 0.1 mA enables reliable clamping below logic-high thresholds in 1.8 V/3.3 V systems |
| Fast switching | 5 ns tRR supports transient suppression on high-speed digital interfaces without signal distortion |
| PN junction guard ring | Enhances ESD robustness to >8 kV HBM and improves immunity to system-level transients |
| AEC-Q101 qualification | Validated for automotive underhood and cabin applications with full PPAP documentation support |
| Symmetrical configuration | No orientation indicator simplifies automated placement and reduces assembly error risk |
Applications
| USB 2.0 Data Line Protection | Automotive LIN Bus Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Same SOT363 package, identical electrical specs, but not AEC-Q101 qualified | Limited to commercial-grade industrial or consumer use; lacks PPAP and IATF16949 traceability | Select when automotive qualification is unnecessary and cost is primary driver |
| NSR20F30NXT5G | Single-channel SOD-523, 30 V/200 mA, VF = 270 mV @ 10 mA, 12 pF CT | Requires two devices for dual-channel function; higher capacitance impacts high-speed signals | Choose only if board space permits discrete placement and dual-device routing |
Compared with SBAT54DW-7-F and NSR20F30NXT5G, BAT54SDWQ-7-F uniquely combines automotive qualification, symmetrical dual-diode integration, and sub-10 pF capacitance-making it the only option qualified for safety-critical vehicle networks where single-part traceability and signal integrity are mandatory.

FAQ
What does the 'SDWQ' suffix indicate in BAT54SDWQ-7-F?
The 'SDWQ' suffix denotes the symmetrical dual-diode configuration in SOT363 package with AEC-Q101 qualification, IATF16949 manufacturing, and green (halogen/antimony-free) compliance. It distinguishes this variant from TWQ (dual common-cathode) and standard BAT54S (non-automotive) versions.
Can BAT54SDWQ-7-F replace BAT54C in existing designs?
No-BAT54C uses SOT23 package with common-cathode topology (pins: Anode1, Anode2, Cathode), while BAT54SDWQ-7-F uses SOT363 with independent anode/cathode pairs (A1/C1, A2/C2) and no shared terminal. Pinout and layout are incompatible without redesign.
Is the SOT363 package compatible with standard reflow profiles?
Yes-the SOT363 package is rated for moisture sensitivity level 1 and supports JEDEC J-STD-020-compliant reflow profiles. Peak temperature must not exceed 260°C for ≤10 seconds, and ramp rates must stay within 3°C/s (max) to avoid delamination or voiding.
Does BAT54SDWQ-7-F support bidirectional signal clamping?
No-it functions as unidirectional clamping only: each diode conducts when its anode exceeds cathode voltage by ≥VF. For bidirectional TVS-like behavior, external series resistors and pull-up/down networks are required; the device itself has no inherent AC symmetry.
