Product details
Overview
BAS16TW-7-F from Diodes Incorporated is a dual-channel surface-mount fast-switching diode array in SOT363 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It delivers high conductance with low forward voltage (0.715 V at 1 mA) and ultra-low leakage (<1.0 µA at 75 V), used in high-speed signal routing and clamping circuits in portable power management and interface protection.
For engineers reviewing the BAS16TW-7-F datasheet, BAS16TW-7-F pinout, BAS16TW-7-F application, or BAS16TW-7-F equivalent, key selection criteria include reverse recovery speed, dual-diode integration in ultra-small footprint, thermal resistance (625 °C/W), and automotive-grade variant availability (BAS16TWQ).
Technical Context
This dual common-anode diode array integrates two independent switching diodes sharing a single anode terminal (Pin 1), enabling compact bidirectional clamping or logic-level steering. Its 4.0 ns trr and low CT (≤2.0 pF at 0 V) support >100 MHz signal integrity in data line protection and level translation.
The device operates across –55 °C to +150 °C, with 200 mW total package power dissipation and defined derating above 25 °C ambient. Its SOT363 package uses matte tin-plated alloy-42 leads, J-STD-020D Level 1 moisture sensitivity, and UL 94V-0 molding compound.

Pinout & Package
SOT363 package: 6-pin, dual-diode configuration with common anode (Pin 1), cathode A (Pin 2), cathode B (Pin 3), and symmetric complementary terminals (Pins 4–6 unused in this dual-common-anode variant per internal schematic).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Common Anode | Shared anode connection for both diodes; ties to positive supply or logic-high reference |
| Pin 2 | Cathode A | Output node for first diode; routes signal or clamps to ground/VREF |

Applications
| USB Data Line Protection | I²C Bus Clamping |
|---|---|
Use Scenario: Protecting D+ and D– lines against ESD and overvoltage transients in portable USB peripherals. IC Role / Device Role / Timing Role: Dual-diode clamping array with common-anode configuration referenced to VCC, shunting transients to rail. Use Value: 4.0 ns trr prevents signal distortion during 480 Mbps high-speed USB data bursts. | Use Scenario: Preventing bus lock-up by clamping SDA/SCL spikes in multi-master I²C systems. IC Role / Device Role / Timing Role: Bidirectional voltage limiter tied between pull-up rail and signal lines, leveraging low CT. Use Value: ≤2.0 pF capacitance avoids timing skew on 400 kHz standard-mode and 1 MHz fast-mode I²C clocks. |
| Logic-Level Translation | Power Rail OR-ing |
Use Scenario: Isolating mixed-voltage domains (e.g., 1.8 V MCU to 3.3 V sensor) without active level shifters. IC Role / Device Role / Timing Role: Passive diode-based level translator using forward conduction threshold to block backflow. Use Value: 0.715 V VF at 1 mA ensures reliable turn-on margin while minimizing voltage offset. | Use Scenario: Combining redundant 5 V power sources in industrial controllers with automatic source selection. IC Role / Device Role / Timing Role: Common-anode OR-ing diode pair directing current from higher-voltage rail while blocking reverse flow. Use Value: 300 mA IF rating supports up to 1.5 W per rail in parallel power architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual fast-switching diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD4148TW-7-F | Identical SOT363 package and pinout; same VRWM (75 V), but slightly higher VF (0.855 V @ 10 mA) and identical trr (4.0 ns) | Same clamping and switching roles; minor VF difference affects low-current bias accuracy | Select when legacy MMBD4148 compatibility is required in existing designs |
| BAS21DW-7-F | Higher VRWM (200 V), same SOT363, but slower trr (50 ns); shares common-cathode topology instead of common-anode | Used where higher reverse voltage tolerance is needed, but unsuitable for common-anode clamping configurations | Choose only if system requires >100 V blocking and circuit layout accommodates cathode-common orientation |
Compared with MMBD4148TW-7-F, BAS16TW-7-F offers lower VF at low currents for precision biasing; versus BAS21DW-7-F, it provides faster switching and correct anode-common topology for rail-referenced clamping-critical for USB/I²C protection.

FAQ
What is the pin configuration of BAS16TW-7-F?
BAS16TW-7-F uses a dual-common-anode configuration in SOT363: Pin 1 is the shared anode, Pins 2 and 3 are independent cathodes, and Pins 4–6 are no-connect terminals. This layout is confirmed in the DS30154 Rev. 15–2 top-view schematic and mechanical drawing.
Is BAS16TW-7-F suitable for automotive applications?
The standard BAS16TW-7-F is not AEC-Q101 qualified, but Diodes offers the automotive-compliant BAS16TWQ variant with identical electrical specs and SOT363 packaging, explicitly designed for infotainment, ADAS, and body electronics per AEC-Q101 stress testing.
How does BAS16TW-7-F compare to single-diode SOT23 equivalents?
Compared to single SOT23 diodes like 1N4148W, BAS16TW-7-F integrates two matched diodes in half the board area, with tighter parameter matching (VF, trr) and reduced parasitic inductance due to shared leadframe-critical for differential signal protection and timing-critical clamping.
What is the maximum operating temperature for continuous use?
BAS16TW-7-F supports continuous operation from –55 °C to +150 °C junction temperature. At 25 °C ambient, its 200 mW power rating allows full 300 mA forward current; derating begins linearly above 25 °C per the published 625 °C/W RθJA curve.
