Product details
Overview
BAS70BRW-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode array in SOT363 package, configured as a dual common-cathode pair with 70 V reverse voltage rating, 1.0 mA forward current capability, and 410 mV max forward voltage at 1.0 mA. It delivers ultra-low leakage (≤100 nA at 50 V), 5.0 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability in polarity protection and data-line clamping.
For engineers reviewing the BAS70BRW-7-F datasheet, BAS70BRW-7-F pinout, BAS70BRW-7-F application, or BAS70BRW-7-F equivalent, this part supports high-efficiency low-current rectification, rail-to-rail ESD protection on bidirectional signal lines, and compact multiplexing circuits where space-constrained dual-diode functionality and fast switching are critical.
Technical Context
This dual-common-cathode Schottky array integrates two independent anode terminals (A1, A2) sharing one cathode (C1), enabling independent forward conduction paths with matched electrical characteristics. Its guard-ringed PN junction structure provides transient and ESD robustness without external components.
The device operates across –55 °C to +125 °C, maintains ≤2.0 pF capacitance at 0 V bias, and sustains 100 mA non-repetitive surge current-making it suitable for low-power signal routing and protection in battery-powered and automotive control 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 |
|---|---|---|---|
| BAS70DW-05-7-F | Identical SOT363 package and electrical specs; symmetrical dual-anode/dual-cathode configuration (no common terminal). | Requires separate cathode routing; less optimal for shared-ground protection schemes like USB or LIN. | Select when independent cathode control is needed for bidirectional current steering. |
| NSR0230HT1G | Single Schottky in SOD-523 (0.6 × 0.3 mm); 30 V VR, 200 mA IF, 450 mV VF - not dual, lower voltage rating. | Cannot replace dual-function requirement; only suitable for single-line protection or rectification. | Choose only if board space is tighter than 1.0 mm² and system voltage stays below 30 V. |
Compared with BAS70DW-05-7-F, BAS70BRW-7-F simplifies grounding in common-cathode topologies, reducing trace count and parasitic inductance; versus NSR0230HT1G, it delivers dual-channel integration and higher 70 V blocking-critical for 24 V industrial and 12 V automotive systems.

FAQ
What is the maximum continuous forward current rating for BAS70BRW-7-F?
The maximum continuous forward current (IFM) is 70 mA at TA = +25°C. Derating applies above 25°C: power dissipation drops linearly to zero at +125°C per the 200 mW absolute maximum rating and 625 °C/W thermal resistance. This rating assumes FR-4 PCB mounting with Diodes' recommended pad layout.
Is BAS70BRW-7-F suitable for bidirectional signal line protection?
Yes - its dual-anode/common-cathode configuration allows independent forward conduction from either A1 or A2 to C1, enabling rail-to-rail clamping on differential or bidirectional lines (e.g., I²C SDA/SCL). The 2.0 pF capacitance and 5.0 ns tRR preserve signal integrity up to 10 MHz without added filtering.
How does the guard ring structure improve ESD robustness?
The integrated PN junction guard ring surrounds each Schottky anode, providing controlled lateral current spreading during ESD events. This structure achieves ≥2 kV HBM per IEC 61000-4-2 without external components, verified under AEC-Q101 testing, and prevents localized thermal runaway during fast transients.
Can BAS70BRW-7-F replace two discrete BAS70-04 diodes?
No - BAS70-04 is a single-die SOT23 Schottky diode. BAS70BRW-7-F integrates two diodes in SOT363 with shared cathode, offering different pinout, thermal behavior, and layout constraints. Direct replacement requires PCB redesign to accommodate 6-pin SOT363 and verify common-cathode topology compatibility.
