Product details
Overview
BAW56W-7 from Diodes Incorporated is a dual surface-mount switching diode in SOT323 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time, optimized for high-speed signal routing and general-purpose switching in compact consumer and industrial electronics.
For engineers reviewing the BAW56W-7 datasheet, BAW56W-7 pinout, BAW56W-7 application, or BAW56W-7 equivalent, key selection criteria include its dual-common-cathode configuration, low 2.0 pF junction capacitance at 0 V, fast trr performance, RoHS-compliant green molding compound, and thermal resistance of 625 °C/W on FR-4 PCB.
Technical Context
The BAW56W-7 integrates two independent silicon switching diodes in a single SOT323 package with common cathode connection, enabling space-efficient dual-path signal control. Its design targets low-capacitance, low-forward-voltage switching in RF front-ends, logic-level translation, and protection circuits where layout density and speed are critical.
It operates across –55 °C to +150 °C, supports 100 V non-repetitive peak reverse voltage, and delivers stable reverse leakage (≤50 µA at 75 V, 25 °C) and forward voltage (0.855 V at 10 mA), validated under JEDEC-standard thermal conditions on 2 oz copper FR-4.

Applications
| RF Signal Steering | Logic-Level Translation |
|---|---|
Use Scenario: Directional switching of 800 MHz–2.4 GHz antenna signals between transceiver and diversity receiver paths. IC Role / Device Role / Timing Role: Dual-anode, common-cathode diode switch controlling RF path continuity via DC bias control. Use Value: 2.0 pF capacitance and 4.0 ns trr preserve signal integrity and minimize insertion loss below –0.3 dB at 2.4 GHz. | Use Scenario: Level-shifting 3.3 V microcontroller GPIO outputs to interface with 5 V legacy peripherals. IC Role / Device Role / Timing Role: Clamping diode pair limiting input voltage swing to safe thresholds while passing logic edges. Use Value: 0.855 V VF at 10 mA ensures reliable turn-on margin; 75 V VRWM prevents breakdown during transient overvoltage events. |
| ESD Protection Network | Power Supply OR'ing |
Use Scenario: Secondary ESD clamp on USB 2.0 D+/D− lines in portable devices, downstream of primary TVS. IC Role / Device Role / Timing Role: Low-capacitance steering diode shunting fast transients (<1 ns rise) to ground rail. Use Value: 2.0 pF CT avoids signal degradation; ≤50 µA IR at 75 V ensures negligible standby leakage. | Use Scenario: Diode-OR configuration selecting between two 3.3 V power rails (e.g., main + backup) in embedded systems. IC Role / Device Role / Timing Role: Dual-anode diode isolating sources while sharing common output cathode to load. Use Value: 300 mA IF rating supports typical MCU + sensor loads; 0.855 V VF limits voltage drop to <3% at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-7-F | Same SOT323 package, identical dual-common-cathode topology; VRWM = 70 V, trr = 4.0 ns, CT = 2.0 pF | Lower 70 V reverse rating reduces margin in 5 V rail-clamp designs near 75 V transients | Select when 70 V blocking suffices and cost optimization is prioritized |
| MMBD7000LT1G | SOT23 package, dual-common-anode; VRWM = 70 V, trr = 4.0 ns, CT = 2.0 pF | Common-anode topology requires inverted biasing; incompatible pinout necessitates PCB redesign | Choose only if existing SOT23 layout exists and anode-referenced switching is required |
Compared with BAV99W-7-F and MMBD7000LT1G, the BAW56W-7 offers higher 75 V reverse blocking and common-cathode polarity-critical for ground-referenced clamping and simplified bias network design in multi-rail systems.

FAQ
What is the pin configuration of the BAW56W-7?
The BAW56W-7 uses a 3-pin SOT323 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This dual-common-cathode arrangement allows independent forward biasing of each diode while sharing a single return path, verified in the DS30064 Rev. 14 top-view schematic and mechanical drawing.
Is the BAW56W-7 suitable for automotive applications?
The BAW56W-7 is not AEC-Q101 qualified; only the BAW56WQ-7-F variant carries that qualification. The standard BAW56W-7 meets industrial temperature range (–55 °C to +150 °C) and green material requirements but lacks PPAP documentation and IATF 16949-controlled change management needed for automotive production.
How does the BAW56W-7's thermal performance compare to SOT23-packaged equivalents?
With RθJA = 625 °C/W on FR-4 (2 oz copper), the BAW56W-7 dissipates 200 mW at 25 °C ambient. Its SOT323 package has ~25% smaller footprint than SOT23 but similar thermal resistance due to optimized leadframe plating and mold compound; derating follows the linear curve in Figure 1.
Can the BAW56W-7 replace a single discrete diode in a circuit?
Yes, but only one diode element should be used with the other anode left unconnected; the common cathode must still be tied to the reference node. Unused anode exhibits no parasitic interaction, and leakage remains within spec (≤2.5 µA at 75 V), confirmed in Electrical Characteristics Table on page 2 of DS30064.
