Product details
Overview
BAW56DWQ-7-F from Diodes Incorporated is a dual high-speed switching diode array in SOT363 package, featuring two independent BAW56 circuits with 75 V peak repetitive reverse voltage, 300 mA forward current rating, and 4.0 ns reverse recovery time-used for signal routing, polarity protection, and clamp circuits in automotive body control modules and industrial I/O interfaces.
For engineers reviewing the BAW56DWQ-7-F datasheet, BAW56DWQ-7-F pinout, BAW56DWQ-7-F application, or BAW56DWQ-7-F equivalent, key selection criteria include reverse recovery time, dual-diode integration in ultra-small SOT363, AEC-Q101 qualification, low forward voltage at 10 mA, and thermal resistance of 625 °C/W under standard FR-4 mounting.
Technical Context
This dual diode array integrates two identical high-conductance silicon switching diodes in a single 6-pin SOT363 package, sharing no internal connection between anodes or cathodes-enabling independent use as discrete clamps or series switches. Each element supports 75 V reverse blocking and exhibits 0.855 V max forward voltage at 10 mA.
The device is characterized for operation from −65 °C to +150 °C, qualified to AEC-Q101 for automotive reliability, and features ultra-low 2.0 pF junction capacitance at 0 V bias-critical for RF signal path isolation and high-frequency digital signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Repetitive Reverse Voltage | 75 V - Enables use in 24 V automotive supply rail clamping without breakdown |
| Reverse Recovery Time | 4.0 ns - Supports >100 MHz digital signal switching and fast transient suppression |
| Forward Voltage @ 10 mA | 0.855 V max - Minimizes conduction loss in low-voltage logic-level protection circuits |
| Junction Capacitance | 2.0 pF @ 0 V - Preserves signal integrity in high-speed data lines (e.g., CAN, LIN) |
| Thermal Resistance θJA | 625 °C/W - Requires minimal PCB copper area for thermal management on FR-4 |
| AEC-Q101 Qualified | Yes - Validated for automotive under-hood and body electronics applications |
Pinout & Package

Applications
| Automotive Body Control Unit (BCU) | Industrial PLC Digital Input Module |
|---|---|
Use Scenario: Protecting microcontroller GPIO pins from inductive kickback of solenoid drivers and relay coils. IC Role / Device Role: Dual clamping diode providing bidirectional transient suppression on two independent input channels. Use Value: Prevents latch-up and ESD damage using single SOT363 footprint instead of two discrete SOD-323 devices. | Use Scenario: Level-shifting and overvoltage protection for 24 V DC field sensor inputs interfacing to 3.3 V logic. IC Role / Device Role: Series-connected switching diode isolating fault currents while enabling normal signal pass-through. Use Value: Achieves <1.0 V forward drop at 10 mA, preserving noise margin and reducing power dissipation vs. Zener-based solutions. |
| USB Port ESD Protection | RS-485 Transceiver Clamp Network |
Use Scenario: Secondary ESD protection stage downstream of TVS diodes on USB D+/D− lines. IC Role / Device Role: Low-capacitance shunt diode limiting line voltage to safe levels during ±8 kV HBM events. Use Value: 2.0 pF capacitance avoids signal integrity degradation at 480 Mbps USB 2.0 speeds. | Use Scenario: Common-mode voltage clamping in half-duplex RS-485 transceivers operating in noisy factory environments. IC Role / Device Role: Dual diode pair connecting A/B lines to VCC and GND to limit differential swing beyond ±12 V. Use Value: 75 V reverse rating ensures robustness against induced surges up to ±70 V common-mode transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-7-F | Same SOT363 package; 70 V VRWM, 3.0 ns trr, 1.25 V VF @ 150 mA | Lower reverse voltage rating limits use in 24 V systems with high transient margins | Select when faster recovery (<3 ns) is prioritized over 75 V blocking capability |
| DMN2016LFG-7 | Single-channel SOT-363 MOSFET switch; 20 V VDS, 1.6 Ω RDS(on); no diode function | Not a diode replacement; used for active low-loss switching, not passive clamping | Choose only for active switching where gate control and bidirectional conduction are required |
Compared with BAV99W-7-F, BAW56DWQ-7-F offers higher reverse voltage margin (75 V vs. 70 V) and lower forward voltage at low current, making it preferable for 24 V automotive clamping; DMN2016LFG-7 serves a fundamentally different circuit role and cannot substitute for passive diode functions.

FAQ
Is BAW56DWQ-7-F pin-compatible with BAW56DW-7-F?
Yes-both share identical SOT363 packaging, pin assignment, and electrical specifications. The "Q" suffix denotes tape-and-reel packaging optimized for automated assembly, with no functional or mechanical difference from the non-Q variant.
What is the maximum continuous forward current per diode element?
The maximum continuous forward current per diode is 300 mA at 25 °C ambient, derated linearly above 25 °C per the 625 °C/W thermal resistance curve-reaching 150 mA at 125 °C ambient when mounted on standard FR-4 with recommended pad layout.
Can BAW56DWQ-7-F replace a single BAW56 diode in existing designs?
No-it contains two independent diodes in one package and cannot be used as a drop-in replacement for a single-diode SOT-23 part without board layout revision. Its pinout (6-pin SOT363) differs fundamentally from the 3-pin SOT-23 BAW56.
Does this device support bidirectional ESD protection?
No-each diode is unidirectional. For bidirectional protection, external configuration (e.g., back-to-back pairing with another BAW56DWQ-7-F or use of dedicated TVS arrays) is required. The device itself conducts only anode-to-cathode.
