Product details
Overview
BAV70E6433HTMA1 from Nexperia is a silicon double diode in common-cathode configuration housed 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 switching in signal routing and clamping circuits within automotive body control modules.
For engineers reviewing the BAV70E6433HTMA1 datasheet, BAV70E6433HTMA1 pinout, BAV70E6433HTMA1 application, or BAV70E6433HTMA1 equivalent, this dual switching diode supports fast transient response, low forward voltage at 100 mA (1.2 V max), and AEC-Q101 qualification for under-hood electronics requiring robust thermal performance and RoHS compliance.
Technical Context
This dual diode integrates two independent PN junctions sharing a single cathode terminal, enabling compact bidirectional clamping or steering functions without cross-conduction risk. Its 1.5 pF capacitance at 0 V and 4 ns trr support >100 MHz signal integrity in ESD protection paths and data line conditioning.
The SC74 package delivers 240 K/W junction-to-soldering-point thermal resistance, allowing sustained 200 mA operation up to 90 °C case temperature. Reverse leakage remains ≤0.15 µA at 70 V/25 °C and ≤50 µA at 70 V/150 °C-critical for low-power sensor interface bias networks.

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 |
|---|---|---|---|
| BAV99,115 (Nexperia) | SOT-23 package; single anode/cathode pair; 4 ns trr, 1.25 V VF @ 100 mA | Lacks dual-anode configuration; requires two devices for common-cathode function | Select when board layout permits discrete placement and thermal budget allows higher RthJA |
| MMBD7000LT1G (onsemi) | SOT-23-3 package; common-cathode dual; 6 ns trr, 1.25 V VF @ 100 mA, 100 V VR | Higher VR margin but slower switching; not AEC-Q101 qualified | Select for industrial non-automotive use where 100 V standoff outweighs speed requirement |
Compared with BAV99,115 and MMBD7000LT1G, BAV70E6433HTMA1 uniquely combines AEC-Q101 qualification, SC74 space efficiency, and 4 ns trr in a common-cathode dual configuration-making it optimal for automotive signal integrity-critical placements where footprint and reliability are jointly constrained.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C, verified per AEC-Q101 test conditions. Continuous operation at this limit requires maintaining case temperature ≤90 °C, as specified for the BAV70U variant in the SC74 package, with derating applied above that point per the IF vs. TS curves in the datasheet.
Is Pin 1 orientation defined for automated placement from tape-and-reel?
No-per the package drawing, symmetric SC74 reels have no defined Pin 1 orientation. Placement machines must rely on optical recognition of the laser-marked "A4s" identifier or side-notch detection; manual verification is recommended during first-article inspection.
How does the 240 K/W RthJS value impact thermal design?
This junction-to-soldering-point resistance means a 250 mW power dissipation generates a 60 K temperature rise from solder joint to junction. Designers must ensure PCB copper area and reflow profile maintain solder joint temperature ≤90 °C to keep Tj ≤150 °C, especially in sealed enclosures with limited airflow.
Can BAV70E6433HTMA1 replace BAV99 in existing layouts?
No-BAV70E6433HTMA1 uses SC74 (6-pin) while BAV99 uses SOT-23 (3-pin); pad layout, stencil design, and pick-and-place programming are incompatible. A redesign is required to accommodate the dual-anode/common-cathode SC74 footprint and verify thermal performance under identical operating conditions.
