Product details
Overview
BAT54SDW-7-F from Diodes Incorporated is a dual-channel Schottky barrier diode array in SOT363 package, configured as two independent anode-cathode pairs sharing a common cathode (common-cathode dual diode). It delivers 30 V peak reverse voltage, 200 mA continuous forward current, and 240–1000 mV forward voltage across 0.1–100 mA test conditions. Used in polarity protection, signal clamping, and OR-ing circuits in portable power management.
For engineers reviewing the BAT54SDW-7-F datasheet, BAT54SDW-7-F pinout, BAT54SDW-7-F application, or BAT54SDW-7-F equivalent, key selection criteria include low VF at low currents (<320 mV @ 1 mA), fast 5.0 ns reverse recovery time, 10 pF junction capacitance at 1 V, and symmetrical SOT363 footprint compatibility with space-constrained DC-DC and USB interface designs.
Technical Context
This device implements two monolithic Schottky junctions on a single silicon die, each with a PN junction guard ring for ESD and transient robustness. The common-cathode configuration enables dual-input single-output rectification or bidirectional clamping without external node tying.
Thermal performance is defined for mounting on 1-layer FR-4 PCB with 2 oz copper; RθJA = 625°C/W limits power dissipation to 200 mW at +25°C ambient. Derating begins above +25°C, supporting operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage before breakdown; sets upper limit for input rail protection in 3.3 V/5 V systems. |
| IF | 200 mA - Continuous forward current per diode; supports low-power signal routing and biasing without thermal runaway. |
| VF @ 1 mA | ≤320 mV - Low conduction loss at micro-power logic-level signals; critical for battery voltage monitoring accuracy. |
| tRR | 5.0 ns - Fast switching speed enables use in >10 MHz signal clamping and high-frequency DC-DC feedback paths. |
| CT @ 1 V | ≤10 pF - Minimal junction capacitance preserves signal integrity in RF detector and high-speed data line protection. |
| IR @ 25 V | ≤2.0 µA - Low leakage maintains precision in high-impedance sensor bias networks and reference dividers. |
Pinout & Package
SOT363 (SC-88) surface-mount package: 2.0 × 2.225 mm body, 0.65 mm lead pitch, 0.006 g weight, UL 94V-0 rated molded plastic housing. Matte tin-plated leads meet MIL-STD-202 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first Schottky path; connects to supply or signal source requiring unidirectional conduction. |
| 2 (A2) | Anode of Diode 2 | Independent input node for second Schottky path; enables dual-source OR-ing or differential clamping. |
| 3 (C1) | Cathode (Common) | Shared output node for both diodes; simplifies PCB routing in common-cathode topologies like power rail OR-ing. |
| 4 (C2) | Cathode (Common) | Redundant cathode terminal; electrically tied to Pin 3 internally-used for mechanical stability and thermal relief. |
| 5 (AC1) | Anode of Diode 1 (Alternate) | Same function as Pin 1; symmetrical marking allows orientation-agnostic placement on automated assembly lines. |
| 6 (AC2) | Anode of Diode 2 (Alternate) | Same function as Pin 2; ensures consistent electrical behavior regardless of top-side marking alignment. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 240–1000 mV range across 0.1–100 mA enables <1% voltage drop in 3.3 V rail protection and extends battery runtime. |
| Guard ring protection | Integrated PN junction guard ring suppresses ESD events up to ±8 kV HBM, eliminating need for external TVS in Class 1B I/O interfaces. |
| Ultra-small footprint | SOT363 package occupies only 4.45 mm² PCB area-ideal for wearables, TWS earbuds, and miniaturized USB-C port protection. |
| Lead-free & green compliance | Fully RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb; meets automotive and medical regulatory requirements without exemptions. |
Applications
| USB Power Path Management | Logic-Level Signal Clamping |
|---|---|
Use Scenario: Dual VBUS and CC line protection in USB-C receptacles where separate 5 V and 3.3 V rails require independent reverse-current blocking. IC Role / Device Role / Timing Role: Common-cathode dual Schottky diode providing simultaneous OR-ing and polarity enforcement without cross-talk. Use Value: Eliminates need for two discrete SOD-323 diodes, reducing BOM count by 50% and saving 1.8 mm² board space per port. | Use Scenario: Protecting GPIO pins of ultra-low-power MCUs (e.g., STM32L0, nRF52) against overvoltage transients during hot-plug events. IC Role / Device Role / Timing Role: Fast-switching clamp limiting input voltage to VDD + 0.3 V while absorbing sub-10 ns ESD pulses. Use Value: 5.0 ns tRR ensures clamping action completes before MCU input latch samples corrupted data, preventing register corruption. |
| DC-DC Feedback Divider Protection | Low-Power Sensor Biasing |
Use Scenario: Isolating feedback resistors in buck converter ICs (e.g., TPS62130, MP2143) from load-dump transients on the output rail. IC Role / Device Role / Timing Role: Schottky diode placed between FB pin and output rail to block reverse current during startup or fault conditions. Use Value: 240 mV VF @ 0.1 mA prevents loading of high-impedance divider (e.g., 1 MΩ/200 kΩ), preserving regulation accuracy within ±0.5%. | Use Scenario: Providing stable bias current to MEMS microphone or thermistor networks in always-on IoT nodes powered by coin cells. IC Role / Device Role / Timing Role: Low-leakage (≤2.0 µA) diode used in constant-current source topology to set sensor excitation current. Use Value: Sub-µA IR ensures <0.1% error in 10 µA bias sources, enabling ±0.1°C temperature resolution in battery-operated environmental monitors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMN2016LFG-7 | Single N-channel MOSFET with integrated gate resistor; not a diode-relies on channel conduction for low-VF behavior. | Used for active OR-ing with reverse-current blocking control; requires gate drive, unlike passive BAT54SDW-7-F. | Select when dynamic control of conduction path is needed; avoid if simplicity and zero-control-signal operation are required. |
| RB521S-30T2R | Single Schottky diode in SOD-523; lacks dual configuration and common-cathode topology. | Requires two devices and extra trace routing to replicate BAT54SDW-7-F's dual-anode/common-cathode function. | Choose only when design already uses SOD-523 footprints and dual functionality is implemented discretely. |
Compared with DMN2016LFG-7 and RB521S-30T2R, BAT54SDW-7-F provides native dual-channel integration with no external control or layout overhead-reducing component count, PCB area, and assembly cost in fixed-function clamping and OR-ing roles.

FAQ
What is the maximum junction temperature rating for BAT54SDW-7-F?
The device is rated for operation from –65°C to +150°C junction temperature. At ambient temperatures above +25°C, derating applies: average rectified current drops linearly to zero at +150°C, per Figure 4 in the datasheet. Thermal resistance is 625°C/W on standard FR-4 PCB.
Is BAT54SDW-7-F suitable for automotive applications?
A qualified automotive-grade version-BAT54SDWQ-7-F-is available under a separate datasheet (DS30152Q) with AEC-Q101 qualification, extended temperature range, and enhanced process controls. The standard BAT54SDW-7-F is not AEC-Q101 certified and should not be used in safety-critical automotive systems.
How does the symmetrical marking (A1/A2/C1/C2/AC1/AC2) affect PCB layout?
Symmetrical marking means the device has no orientation dependency-the same electrical function appears on Pins 1&2 (anodes) and Pins 5&6 (anodes), with Pins 3&4 both serving as the common cathode. This allows placement in either direction on pick-and-place machines, improving assembly yield and eliminating orientation verification steps.
Can BAT54SDW-7-F replace BAT54CDW-7-F in a design?
Yes-both share identical SOT363 package, electrical specs, and thermal characteristics. The difference lies only in internal connection: BAT54CDW-7-F is common-anode, while BAT54SDW-7-F is common-cathode. Replacement requires verifying circuit topology matches the cathode-common configuration to maintain correct current flow direction.
