Product details
Overview
BAW56W from Nexperia is a dual high-speed switching diode in common-anode configuration, housed in an SOT323 (SC-70) package. It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 2 pF capacitance, and VR = 90 V, enabling fast signal routing and low-distortion clamping in RF front-ends and digital logic interfaces.
For engineers reviewing the BAW56W datasheet, BAW56W pinout, BAW56W application, or BAW56W equivalent, key selection criteria include verified dual-diode timing symmetry, common-anode thermal coupling behavior, SOT323 footprint compatibility with high-density PCB layouts, and leakage performance at 80 V reverse bias and 150 °C junction temperature.
Technical Context
The BAW56W integrates two identical silicon switching diodes sharing a single anode terminal, forming a compact dual-diode structure optimized for bidirectional signal steering and voltage clamping. Its design targets minimal charge storage and low parasitic capacitance to support >100 MHz switching in RF detector and protection circuits.
Reverse recovery is characterized under standardized IF = 10 mA / IR = 10 mA / RL = 100 Ω conditions with IR(meas) = 1 mA, yielding trr ≤ 4 ns. Forward conduction exhibits VF = 855 mV at 10 mA and VF = 1.25 V at 150 mA, confirming low on-resistance operation within its 130 mA continuous forward current rating.
Key Specifications

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 | Higher trr (≤ 6 ns), higher Cd (≤ 3 pF), same SOT323 package and common-anode pinout | Marginally lower RF bandwidth support; acceptable where <100 MHz operation suffices | Select when cost sensitivity outweighs sub-4 ns timing requirement and 2 pF capacitance is noncritical |
| MMBD7000LT1G | Lower VR (100 V), higher IR (≤ 1 µA at 80 V), same dual-common-anode topology and SOT23-3 package | Not pin-compatible (SOT23 vs SOT323); requires PCB redesign but offers higher reverse voltage margin | Choose only if board layout allows SOT23 footprint change and 100 V VR is required for 48 V system derating |
Compared with BAV99W and MMBD7000LT1G, the BAW56W uniquely balances 4 ns trr, 2 pF Cd, and SOT323 compatibility-making it optimal for space-constrained, >100 MHz signal path protection without footprint or thermal compromise.

FAQ
What is the maximum continuous forward current rating for BAW56W?
The BAW56W is rated for 130 mA continuous forward current (IF) at Tamb ≤ 25 °C when mounted on a standard FR4 PCB with single-sided copper. This rating drops with increasing ambient temperature and is limited by its 200 mW total power dissipation capability and 625 K/W junction-to-ambient thermal resistance.
Is BAW56W suitable for automotive applications?
No. The BAW56W is explicitly designated as non-automotive qualified per Nexperia's 2022 revision history. It has not undergone AEC-Q101 stress testing or automotive-grade qualification. For automotive use, Nexperia recommends its -Q qualified alternatives such as the BAW56W-Q series, which undergo extended temperature and reliability validation.
How does the common-anode configuration affect PCB layout?
The common-anode (CA) pin simplifies biasing by allowing a single connection to VCC or reference potential, reducing trace count and improving layout symmetry. In clamping applications, CA ties directly to the protected rail, while K1 and K2 route to signal lines-enabling compact, balanced dual-path protection without discrete pull-up resistors.
Can BAW56W replace BAV99 in existing SOT323 designs?
Yes-BAW56W shares identical SOT323 pinout (K1–K2–CA), mechanical dimensions, and solder footprint with BAV99. However, its lower trr (4 ns vs 6 ns) and Cd (2 pF vs 3 pF) may require verification of timing margins and signal integrity in legacy designs originally validated with BAV99's slightly slower characteristics.
