Product details
Overview
BAV99SH6433XTMA1 from Nexperia is a silicon dual-series switching diode in SC74 (SOT-363) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, optimized for high-speed signal routing and ESD protection in automotive infotainment data lines.
For engineers reviewing the BAV99SH6433XTMA1 datasheet, BAV99SH6433XTMA1 pinout, BAV99SH6433XTMA1 application, or BAV99SH6433XTMA1 equivalent, this part supports AEC-Q101 qualified designs requiring low capacitance (1.5 pF), fast switching, and thermal robustness up to 150 °C junction temperature.
Technical Context
This dual-diode configuration connects two epitaxial planar diodes in series within a single SC74 package, enabling bidirectional clamping or polarity-selective signal steering. Its 1.5 pF capacitance at 0 V and 4 ns trr support >100 MHz digital signal integrity in USB 2.0 and CAN FD interface protection paths.
The device operates with a maximum VF of 1.25 V at 150 mA and exhibits IR ≤ 0.15 µA at 70 V and 25 °C, ensuring minimal leakage in battery-backed circuits. Thermal resistance RthJS is ≤ 260 K/W, validated for TS ≤ 85 °C derating per Nexperia's BAV99S specification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | Same die, SOT-323 package; higher RthJS (≤160 K/W) but lower Ptot (250 mW vs. 250 mW); identical trr/CT. | Preferred for space-constrained PCBs where 3-pin footprint suffices and thermal mass is limited. | Select when board area is critical and thermal budget allows tighter derating. |
| MMBD7000LT1G | Higher VF (1.25 V typ @ 10 mA), same VR (70 V), slightly slower trr (6 ns), RoHS-compliant SOT-23-3. | Suitable for general-purpose logic-level clamping but not AEC-Q101 automotive systems. | Choose only for non-automotive consumer electronics with relaxed reliability requirements. |
Compared with BAV99SH6433XTMA1, BAV99W,115 offers identical electrical performance in a smaller footprint but reduced thermal margin, while MMBD7000LT1G trades AEC-Q101 qualification and speed for broader commercial availability and lower cost.

FAQ
Is BAV99SH6433XTMA1 pin-compatible with standard BAV99S variants?
Yes - BAV99SH6433XTMA1 uses the SC74 (SOT-363) package with identical pin 1 location and terminal mapping as documented in Nexperia's BAV99S datasheet. The 'H6433' suffix denotes tape-and-reel packaging and date code; electrical and mechanical compatibility is fully maintained.
What is the maximum allowable surge current for a single 1 µs pulse?
The absolute maximum non-repetitive peak surge forward current is 4.5 A for t = 1 µs, as specified in Nexperia's BAV99 series datasheet. This rating assumes TJ ≤ 150 °C and applies to single-event ESD or lightning-induced transients, not repetitive switching.
Does this diode require external biasing for bidirectional clamping?
No - the dual-series configuration enables intrinsic bidirectional clamping without external bias. When used between signal and ground, it conducts during both positive and negative transients, leveraging its symmetrical IV characteristics and matched diode pair.
Can BAV99SH6433XTMA1 replace BAT54S in USB data line protection?
No - BAT54S is a dual-common-cathode Schottky diode with VF ≈ 0.3 V and trr > 100 ns, whereas BAV99SH6433XTMA1 is a series-switching silicon diode with VF ≈ 1.25 V and trr = 4 ns. Their conduction behavior and speed profiles are incompatible for direct substitution in low-VF Schottky applications.
