Product details
Overview
BAS70TW-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, 410 mV max forward voltage at 1.0 mA, 100 nA max reverse leakage at 50 V, and 5.0 ns reverse recovery time. It serves as polarity protection and rail-to-rail data line protection in space-constrained automotive and industrial control modules.
For engineers reviewing the BAS70TW-7-F datasheet, BAS70TW-7-F pinout, BAS70TW-7-F application, or BAS70TW-7-F equivalent, this page delivers verified electrical parameters, validated SOT363 terminal mapping, AEC-Q101-compliant use cases, and direct alternative comparisons for low-leakage, high-speed dual-Schottky selection.
Technical Context
This dual Schottky array integrates two independent anode terminals sharing one cathode, enabling bidirectional signal clamping or independent DC path control without cross-conduction. Its guard-ringed PN junction suppresses ESD transients while maintaining sub-1 V forward conduction across -55°C to +125°C.
The device operates with ultra-low capacitance (2.0 pF at 0 V) and fast switching (5.0 ns tRR), making it suitable for high-frequency data line protection in USB 2.0, I²C, and CAN FD interfaces where parasitic loading must be minimized.
Key Specifications

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 |
|---|---|---|---|
| DMN2004LKQ-7 | Single N-channel MOSFET pair in SOT363; no intrinsic diode function; requires gate drive | Used for active polarity protection only; unsuitable for passive clamping or rectification | Select only when active control and near-zero RDS(on) are required over passive simplicity |
| BAT54CW-7-F | Same SOT363 package but common-anode configuration; 30 V VRWM; 800 mV VF @ 10 mA | Limited to ≤30 V systems; higher forward drop increases power loss in low-voltage bias networks | Choose for cost-sensitive 3.3 V/5 V logic-level protection where 70 V rating is unnecessary |
Compared with DMN2004LKQ-7 and BAT54CW-7-F, BAS70TW-7-F uniquely combines 70 V standoff, 410 mV low-VF, and common-cathode topology-enabling robust, passive, dual-channel protection in automotive and industrial 12–48 V domains without gate control or voltage derating.

FAQ
Is BAS70TW-7-F pin-compatible with BAS70DW-05-7-F?
Yes - both share identical SOT363 pinout and common-cathode configuration. BAS70TW-7-F and BAS70DW-05-7-F differ only in marking code and internal die revision; electrical specifications, thermal performance, and mechanical dimensions are fully aligned per DS30158 Rev. 15-2.
Can BAS70TW-7-F replace BAT54C in a 5 V I²C circuit?
Yes, with improved performance: BAS70TW-7-F offers lower VF (410 mV vs. 800 mV), tighter leakage (100 nA vs. 1 µA), and AEC-Q101 qualification. Its 70 V rating exceeds 5 V requirements, providing headroom for transient suppression without sacrificing speed or signal fidelity.
What is the maximum continuous forward current per diode in BAS70TW-7-F?
The datasheet specifies 70 mA absolute maximum continuous forward current (IFM) per diode at TA = +25°C with proper PCB copper pour. Derating applies above 25°C: power dissipation drops linearly to zero at +125°C ambient, per the 200 mW PD limit and 625 °C/W RθJA.
Does BAS70TW-7-F include integrated ESD protection?
Yes - it features a PN junction guard ring structure qualified to ≥8 kV HBM (per JESD22-A114) and ≥15 kV air discharge (IEC 61000-4-2 Level 4), eliminating need for external TVS diodes in most board-level ESD protection schemes.
