Product details
Overview
BAW56M from Nexperia is a dual high-speed switching diode in a common-anode configuration, housed in an ultra-small DFN1006-3 (SOT883) package. It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 2 pF capacitance, and VR = 90 V, enabling reliable operation in automotive signal routing and compact DC-DC converter flyback paths.
For engineers reviewing the BAW56M datasheet, BAW56M pinout, BAW56M application, or BAW56M equivalent, this device supports AEC-Q101-compliant designs requiring low-leakage, fast-switching dual diodes in space-constrained layouts with thermal resistance Rth(j-a) = 500 K/W on FR4 PCBs.
Technical Context
The BAW56M integrates two independent silicon switching diodes sharing a common anode terminal, forming a single-package dual-diode topology optimized for bidirectional signal clamping and polarity-selective current steering. Its design targets minimal charge storage and junction capacitance to sustain sub-4 ns recovery under IF = 10 mA / IR = 10 mA test conditions.
Thermal performance is defined for reflow-soldered mounting on single-sided tin-plated FR4 PCBs, with absolute maximum Tj = 150 °C and Ptot = 250 mW per device. The device operates across –65 °C to +150 °C ambient, meeting automotive-grade reliability requirements without derating below 75 mA continuous forward current.
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,115 | Same SOT323 package but larger footprint (2.1 mm × 1.25 mm); trr = 4 ns, Cd = 2 pF, VR = 70 V | Lacks AEC-Q101 qualification; higher Rth(j-a) ≈ 300 K/W due to larger thermal mass | Select when board space allows larger package and automotive qualification is not required |
| PMEG3010CEAX | Schottky architecture; VF = 380 mV at 100 mA; trr not specified (inherently zero); VR = 30 V only | Lower forward drop improves efficiency but limits use to ≤24 V systems; no reverse recovery noise | Prefer for low-VF, low-noise 12 V power rail clamping where 90 V VR is unnecessary |
Compared with BAV99W and PMEG3010CEAX, the BAW56M uniquely combines AEC-Q101 compliance, 90 V VR rating, and 0.6 mm width in a 3-terminal common-anode layout-enabling automotive-grade dual-diode functionality in space-limited 0201-equivalent footprints.

FAQ
What is the maximum continuous forward current per diode in the BAW56M?
The BAW56M supports 75 mA continuous forward current per diode at Tamb ≤ 25 °C when mounted on an FR4 PCB with single-sided copper. This rating reflects thermal derating from the 150 mA absolute maximum to ensure junction temperature remains below 150 °C under sustained operation with 250 mW total power dissipation.
Is the BAW56M suitable for reflow soldering only, and why?
Yes-the datasheet explicitly states reflow soldering is the only recommended method. The DFN1006-3 package lacks leads suitable for wave soldering, and its ultra-thin profile (0.48 mm) risks mechanical stress or delamination during wave immersion. Reflow profiles must follow Nexperia's SOT883 guidelines to avoid solder voiding or pad lift.
How does the common-anode configuration affect circuit implementation?
The CA terminal serves as the shared anode for both diodes, requiring the anode to be tied to a fixed potential (e.g., VCC or bias rail), while K1 and K2 route independently to separate cathode loads. This topology simplifies bidirectional clamping or dual-path steering but prohibits independent anode biasing-unlike dual-die packages with isolated anodes.
Does the 4 ns trr specification apply across the full operating temperature range?
No-the 4 ns trr is specified at Tamb = 25 °C using IF = 10 mA, IR = 10 mA, RL = 100 Ω, and IR(meas) = 1 mA. At 150 °C junction temperature, trr increases to approximately 6–7 ns due to carrier lifetime extension; designers must verify timing margins in high-temperature environments using Fig. 5 test circuit conditions.
