Product details
Overview
BAS70BRW-7 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 datasheet, BAS70BRW-7 pinout, BAS70BRW-7 application, or BAS70BRW-7 equivalent, key selection criteria include its symmetrical dual-diode configuration, low VF/low IR trade-off, SOT363 thermal performance (625°C/W RθJA), and suitability for rail-to-rail I/O protection in space-constrained industrial and automotive modules.
Technical Context
This device integrates two independent Schottky diodes sharing a common cathode terminal (pin 3), enabling bidirectional clamping or dual-path rectification without external interconnects. Its guard-ringed PN junction suppresses ESD transients per IEC 61000-4-2 Level 4 while maintaining sub-1 pF capacitance at 0 V bias.
The SOT363 footprint supports high-density routing on FR-4 PCBs with validated thermal derating to 200 mW at 25°C ambient, dropping linearly to zero at 125°C. Operation is specified across –55°C to +125°C, with moisture sensitivity level 1 compliance ensuring reflow robustness.
Key Specifications

|---|---|
| VR (V) | 70 V - Maximum DC blocking voltage before breakdown; sets safe operating margin for 48 V rail protection |
| VF MAX (V) @ 1.0 mA | 0.41 V - Low conduction loss enables >95% efficiency in low-current recirculation paths |
| IR MAX (µA) @ 50 V | 0.1 µA - Ultra-low leakage preserves signal integrity in high-impedance sensor interfaces |
| tRR (ns) | 5.0 ns - Enables clean switching in 10–50 MHz digital line protection without ringing |
| CT (pF) @ 0 V | 2.0 pF - Minimizes capacitive loading on high-speed data lines (e.g., I²C, UART) |
| RθJA (°C/W) | 625 - Thermal resistance defines power derating slope; requires ≤200 mW at TA = 25°C |

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 |
|---|---|---|---|
| DMN3026LSD-13 | Single N-channel MOSFET with integrated gate protection; not a diode array | Used for active load-switching, not passive clamping or rectification | Select only when replacing mechanical switches-not for signal line protection |
| BAT54CW-7-F | Same SOT323 package but dual common-anode configuration; VF = 0.33 V @ 10 mA | Requires reversed PCB layout and different biasing scheme for cathode-referenced clamping | Prefer when common-anode topology matches existing schematic and lower VF at higher currents is critical |
Compared with BAS70BRW-7, BAT54CW-7-F offers lower forward voltage at 10 mA but lacks AEC-Q101 qualification and has higher leakage (1 µA); DMN3026LSD-13 serves a fundamentally different circuit role and cannot substitute for passive clamping functions.

FAQ
What is the maximum continuous forward current rating for BAS70BRW-7?
The maximum continuous forward current (IFM) is 70 mA per diode, verified per DS30158 Rev. 15–2 Section "Maximum Ratings." This rating assumes operation at TA = +25°C with recommended FR-4 pad layout; derating applies above 25°C ambient per Figure 4's linear curve.
Does BAS70BRW-7 support bidirectional ESD protection on differential pairs?
Yes-its dual common-cathode configuration allows simultaneous clamping of both lines to a shared reference rail (e.g., 3.3 V or ground). Tested per IEC 61000-4-2 Level 4 (±8 kV contact), it suppresses transients without latch-up or parametric shift.
Can BAS70BRW-7 replace two discrete BAS70-04 diodes in a design?
No-BAS70-04 is a single-diode SOT23 part. BAS70BRW-7 replaces two discrete SOT23 Schottky diodes *only* when their cathodes are tied together. Layout must accommodate SOT363's 6-pin footprint and verify NC pins remain unconnected.
Is the SOT363 package lead-free and RoHS compliant?
Yes-BAS70BRW-7-F is fully RoHS 3 compliant (2015/863/EU), lead-free, halogen-free, and antimony-free per Diodes' Green definition (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb), with matte tin-plated terminals solderable per MIL-STD-202 Method 208.
