Product details
Overview
BAT54TWQ-7-F from Diodes Incorporated is a dual-channel surface-mount Schottky barrier diode array in SOT363 package, rated for 30 V peak reverse voltage, 200 mA continuous forward current, and 240–1000 mV forward voltage (depending on current), with 2.0 µA max reverse leakage at 25 V. It features PN junction guard ring for ESD/transient protection and is AEC-Q101 qualified for automotive power rail clamping and signal steering.
For engineers reviewing the BAT54TWQ-7-F datasheet, BAT54TWQ-7-F pinout, BAT54TWQ-7-F application, or BAT54TWQ-7-F equivalent, this part supports high-speed switching in space-constrained automotive ECUs, USB port protection circuits, and low-voltage logic-level translation where low VF and fast tRR (<5 ns) are critical.
Technical Context
This dual Schottky diode array integrates two independent anode-cathode pairs in a symmetrical SOT363 configuration with no orientation indicator. Each channel delivers low forward voltage (240 mV @ 0.1 mA, 400 mV @ 10 mA) and ultra-fast reverse recovery (tRR ≤ 5.0 ns), enabling efficient clamping and steering in 3.3 V/5 V digital interfaces.
The device employs a PN junction guard ring structure to suppress transient-induced latch-up and meet ±8 kV HBM ESD immunity per AEC-Q101. Its thermal resistance (RθJA = 625 °C/W) and 200 mW power dissipation rating are specified for standard FR-4 PCB mounting with defined pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum DC blocking voltage before breakdown; suitable for 24 V automotive supply rail clamping |
| IF (continuous) | 200 mA - Steady-state forward current per diode; supports logic-level signal routing and small-signal rectification |
| VF @ 10 mA | 400 mV - Low conduction loss at typical interface current; reduces voltage drop in level-shifting paths |
| IR @ 25 V | 2.0 µA - Minimal leakage at near-rated reverse bias; preserves signal integrity in high-impedance nodes |
| tRR | 5.0 ns - Fast recovery enables operation up to ~70 MHz switching; critical for USB 2.0 data line protection |
| CT @ 1 V | 10 pF - Low junction capacitance minimizes signal distortion in high-speed digital I/O lines |
| RθJA | 625 °C/W - Thermal performance measured on standard FR-4 board; defines derating curve above 25 °C ambient |
Pinout & Package
Package: SOT363 - ultra-small plastic surface-mount package (2.15 × 2.10 × 1.0 mm), moisture sensitivity level 1, lead-free matte tin finish over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Input node for first Schottky path; connects to signal source or supply rail requiring clamping |
| C1 | Cathode of Diode 1 | Output/return node for Diode 1; tied to reference (e.g., VCC or GND) for clamping function |
| A2 | Anode of Diode 2 | Independent input for second Schottky path; enables dual-rail or bidirectional signal conditioning |
| C2 | Cathode of Diode 2 | Independent output for Diode 2; allows separate termination to different reference potentials |
| A3 / C3 | Common terminal (symmetrical) | No dedicated common pin; device has no shared anode/cathode - each diode is fully isolated |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 240 mV @ 0.1 mA - Enables reliable turn-on below 0.3 V logic thresholds in battery-powered systems |
| Fast switching speed | tRR ≤ 5 ns - Supports >50 MHz digital signal integrity without pulse distortion in data lines |
| PN junction guard ring | ESD robustness per AEC-Q101 - Provides inherent ±8 kV HBM protection without external TVS devices |
| AEC-Q101 qualification | Automotive-grade reliability - Validated for 15-year operation in under-hood temperature range (−40 to +125 °C) |
| Ultra-small SOT363 footprint | 2.15 × 2.10 mm area - Saves >60% board space vs. SO-8 dual diodes; ideal for compact ADAS modules |

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 (VRRM=30 V, IF=200 mA), but not AEC-Q101 qualified | Limited to commercial/industrial use; lacks PPAP documentation and automotive temperature validation | Select when cost sensitivity outweighs automotive qualification requirements |
| NSR20F30NXT5G | Higher IF (200 mA same), lower VF (220 mV @ 10 mA), but larger SOD-523 package (single diode); dual requires two placements | Not pin-compatible; increases PCB area and assembly cost due to two-component solution | Choose only if lowest possible VF is mandatory and board space is unconstrained |
Compared with SBAT54DW-7-F and NSR20F30NXT5G, BAT54TWQ-7-F uniquely combines AEC-Q101 qualification, symmetrical dual-diode SOT363 integration, and guaranteed 2.0 µA IR at 25 V-making it the only drop-in solution for automotive signal integrity designs requiring both reliability and space efficiency.

FAQ
Is BAT54TWQ-7-F pin-compatible with BAT54SDWQ-7-F?
Yes - both share identical SOT363 pinout and symmetrical dual-diode configuration. BAT54TWQ-7-F uses a "common cathode" internal connection (A1/C1 and A2/C2), while BAT54SDWQ-7-F is "common anode" (A1/A2 and C1/C2). The marking code (KLA vs KL8) and internal topology differ, so direct substitution requires circuit verification.
What is the maximum operating temperature for continuous use?
The device is rated for −65 °C to +125 °C junction and storage temperature. At +125 °C ambient, derated power dissipation is 100 mW (per Fig. 4), limiting continuous IF to ~140 mA with standard FR-4 layout. Full 200 mA rating applies only at ≤+25 °C ambient.
Does BAT54TWQ-7-F support bidirectional signal clamping?
No - each diode conducts only anode-to-cathode. For bidirectional clamping (e.g., ±15 V to 3.3 V rail), two BAT54TWQ-7-F devices are required: one with cathodes tied to VCC (for positive transients), another with anodes tied to GND (for negative transients).
Can this diode be used in RF applications above 1 GHz?
No - its 10 pF junction capacitance and 5 ns reverse recovery time limit effective use to frequencies below ~100 MHz. For RF switching or matching networks above 500 MHz, purpose-built GaAs or PIN diodes with sub-0.5 pF CT are recommended instead.
