Product details
Overview
BAT54BRW-7 from Diodes Incorporated is a surface-mount Schottky barrier diode array in SOT363 package, configured as a dual common-cathode diode with 30 V reverse voltage rating, 200 mA continuous forward current, and 5.0 ns reverse recovery time. It serves in polarity protection and signal clamping circuits in USB interface power rails and low-voltage DC-DC converter feedback paths.
For engineers reviewing the BAT54BRW-7 datasheet, BAT54BRW-7 pinout, BAT54BRW-7 application, or BAT54BRW-7 equivalent, key selection criteria include low VF (≤400 mV at 10 mA), ultra-small footprint, ESD-protected junction guard ring, and thermal resistance of 625°C/W on standard FR-4 PCB.
Technical Context
This dual Schottky diode array integrates two independent anode terminals sharing a common cathode, enabling bidirectional clamping or dual-path rectification in space-constrained layouts. Its PN junction guard ring suppresses transient-induced latch-up and meets IEC 61000-4-2 Level 4 ESD immunity requirements without external protection components.
The device operates across –65°C to +150°C ambient range and maintains stable VF and IR performance up to 125°C junction temperature. Total capacitance remains ≤10 pF at 1.0 V reverse bias, supporting high-frequency signal routing in 10–100 MHz analog switch and RF detector applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - supports 24 V nominal bus systems with 25% safety margin against transients |
| IF (continuous) | 200 mA - sufficient for USB 2.0 VBUS line protection and low-power logic-level translation |
| tRR | 5.0 ns - enables clean switching in 20+ MHz clock distribution and data line clamping |
| VF @ 10 mA | ≤400 mV - reduces conduction loss by >35% vs. standard silicon diodes in 3.3 V rail clamping |
| CT @ 1 V | ≤10 pF - preserves signal integrity in high-speed digital I/O and RF detector front-ends |
| RθJA | 625 °C/W - requires minimal copper pour for thermal management on 2 oz FR-4 boards |
Pinout & Package
Package: SOT363 - ultra-compact 6-pin surface-mount plastic package (2.0 × 2.225 mm footprint, 0.9 mm height), rated UL 94V-0, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode 1 | Independent input path for first Schottky diode; connects to protected source or signal line |
| 2 (A2) | Anode 2 | Independent input path for second Schottky diode; enables dual-rail or redundant clamping |
| 3 (C1) | Cathode (shared) | Common output node tied to system ground or reference rail; carries combined forward current |
| 4 (C2) | Cathode (shared) | Second cathode terminal for low-inductance grounding; required for symmetrical layout in SOT363 |
| 5 (AC1) | Anode 1 (alternate marking) | Same electrical node as Pin 1; used in alternate top-view orientation labeling |
| 6 (AC2) | Anode 2 (alternate marking) | Same electrical node as Pin 2; accommodates asymmetric board assembly verification |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | VF ≤ 400 mV @ 10 mA - minimizes voltage drop in 3.3 V and 5 V power domain isolation |
| Fast switching speed | tRR ≤ 5.0 ns - prevents signal distortion in 20–50 MHz data lines and clock buffers |
| Junction guard ring | Integrated PN ring - eliminates need for discrete TVS in IEC 61000-4-2 ±8 kV contact ESD environments |
| Ultra-small footprint | SOT363 (2.0 × 2.225 mm) - saves >60% board area vs. SO-8 dual diodes in portable USB-C accessories |
Applications
| USB Power Switching | DC-DC Feedback Clamping |
|---|---|
Use Scenario: Bidirectional VBUS path control in USB 2.0 OTG devices with host/peripheral role switching. IC Role / Device Role / Timing Role: Dual-anode Schottky array provides reverse-polarity blocking and overvoltage clamping during role swap transitions. Use Value: Prevents backfeed between VBUS sources while maintaining <100 ns response to 24 V transients via low tRR and guard ring. | Use Scenario: Voltage reference clamping in adjustable buck converter feedback networks using TLV431 or similar shunt regulators. IC Role / Device Role / Timing Role: Common-cathode dual diode limits feedback node swing to ±0.4 V around reference, stabilizing regulation under load step. Use Value: Enables precise 0.5% output tolerance at 1.2 V–5 V outputs without adding series resistance or trimming. |
| RF Detector Input Protection | Logic-Level Translation Clamp |
Use Scenario: Protecting ADL5511 RF power detector inputs from antenna coupling surges in 900 MHz ISM band receivers. IC Role / Device Role / Timing Role: Low-capacitance Schottky clamp limits RF input to ±0.35 V, preserving detector linearity below –30 dBm. Use Value: Maintains CT ≤ 10 pF at 1 V bias to avoid detuning matching networks and degrading return loss. | Use Scenario: Level-shifting 1.8 V GPIO signals to 3.3 V microcontroller inputs with overvoltage protection. IC Role / Device Role / Timing Role: Anode-to-IO pin, cathode-to-3.3 V rail configuration clamps negative excursions and limits positive overshoot. Use Value: Delivers sub-5 ns response to 1.8 V logic glitches without loading source driver due to <10 pF junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DW-7-F | Same SOT363 package, identical VF/tRR specs, but uses different die process resulting in 10% higher IR at 25 V (2.2 µA vs. 2.0 µA) | No functional impact in clamping or low-current rectification; marginal difference in battery-powered always-on leakage-sensitive designs | Select when sourcing flexibility is prioritized and leakage budget allows +0.2 µA worst-case increase |
| BAT54C-7-F | SOT23-3 package, single common-cathode dual diode, same electrical specs but larger footprint (3.0 × 1.4 mm) and higher RθJA (800°C/W) | Not suitable for ultra-dense layouts; requires redesign of pad stack and thermal relief; acceptable only if board space permits | Choose only when legacy SOT23 placement exists and requalification of SOT363 is not feasible |
Compared with SBAT54DW-7-F and BAT54C-7-F, BAT54BRW-7 offers optimal balance of leakage performance, thermal efficiency, and miniaturization-critical for USB-C accessories and wearable sensor hubs where board area and standby current are constrained.

FAQ
What is the maximum junction temperature for BAT54BRW-7 during continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –65°C to +150°C ambient range. At 200 mA IF and 25°C ambient on a standard 2 oz FR-4 board, junction temperature rise is approximately 125°C, leaving 25°C margin before reaching limit.
Can BAT54BRW-7 replace BAT54C-7-F in existing SOT23-3 footprints?
No-BAT54BRW-7 uses SOT363 (6-pin) while BAT54C-7-F uses SOT23-3 (3-pin); pin count, pitch, and pad layout are incompatible. Direct replacement requires PCB redesign, including new stencil apertures and reflow profile validation for the smaller 0.65 mm lead pitch.
Does BAT54BRW-7 meet automotive qualification standards?
No-BAT54BRW-7 is an industrial-grade part. Diodes offers the automotive-compliant BAT54SDWQ-7-F variant, qualified to AEC-Q101 with extended temperature testing, enhanced ESD robustness, and PPAP documentation support.
How does the PN junction guard ring improve system-level ESD performance?
The integrated guard ring prevents edge breakdown during ESD events by distributing electric field stress away from the active junction periphery. This enables the device to withstand IEC 61000-4-2 ±8 kV contact discharge without external TVS, reducing BOM count and PCB area in USB and audio interface designs.
