Product details
Overview
BAV99SE6433HTMA1 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. It supports high-speed signal routing and polarity protection in automotive infotainment power rails and USB data line ESD clamping circuits.
For engineers reviewing the BAV99SE6433HTMA1 datasheet, BAV99SE6433HTMA1 pinout, BAV99SE6433HTMA1 application, or BAV99SE6433HTMA1 equivalent, this device delivers verified AEC-Q101 qualification, low 1.5 pF junction capacitance at 0 V, and thermal resistance of ≤260 K/W (junction-to-soldering point), critical for compact automotive PCB layouts with tight thermal budgets.
Technical Context
This dual-diode configuration connects two epitaxial planar diodes in series within a single SC74 package, enabling bidirectional transient suppression or polarity-selective signal steering. Its 85 V breakdown voltage (IBR = 100 µA) and 0.15 µA reverse leakage at 70 V/25°C ensure stable blocking under nominal bias conditions.
The 4 ns reverse recovery time-measured at IF = IR = 10 mA with 1 mA detection threshold and 100 Ω load-confirms suitability for >100 MHz switching waveforms in RF front-end protection and high-frequency DC-DC converter snubbing.

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 SC74 package but SOT-323 pinout; RthJS ≤160 K/W; VF = 1.2 V @ 150 mA | Higher thermal performance but higher forward drop limits use in low-VF precision clamps | Select when board space allows SOT-323 footprint and junction temperature exceeds 125°C |
| MMBD7000LT1G | SOT-23 package; 100 V VR; trr = 4 ns; CT = 2.5 pF; no AEC-Q101 qualification | Larger capacitance degrades >200 MHz signal integrity; not qualified for automotive production | Acceptable for industrial prototypes where AEC-Q101 is not mandated and layout permits larger pad pitch |
Compared with BAV99SE6433HTMA1, BAV99W offers superior thermal resistance but requires SOT-323 layout adaptation, while MMBD7000LT1G trades automotive qualification for wider voltage margin and simpler sourcing-neither provides identical combination of AEC-Q101, SC74 footprint, and 1.5 pF capacitance.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150°C, validated per JEDEC JESD22-A103. Operation above this limit risks permanent degradation of the epitaxial junction. Derating curves in the datasheet show that at 85°C soldering-point temperature, the device sustains full 200 mA DC current without exceeding Tj = 150°C under specified thermal conditions.
Is pin 1 orientation defined in the tape-and-reel packaging?
No-Nexperia explicitly states "for symmetric types no defined Pin 1 orientation in reel" for SC74-packaged BAV99 variants. Assembly equipment must rely on optical recognition of the pin 1 marking on the component body rather than tape indexing. The marking is a laser-etched dot or notch located adjacent to pin 1 per the package outline drawing.
Can this diode be used in bidirectional TVS applications?
No-BAV99SE6433HTMA1 is a series-connected dual diode, not a back-to-back (anti-parallel) configuration. It conducts only in one direction across pins 1–3. For bidirectional transient suppression, a dedicated TVS array like PESD5V0S1BA must be used; this part serves only unidirectional clamping or polarity control.
How does the 4 ns reverse recovery time impact ESD protection performance?
The 4 ns trr ensures the diode transitions rapidly from conduction to blocking state after an ESD event, preventing latch-up or sustained conduction that could damage downstream ICs. This speed is critical for IEC 61000-4-2 testing, where sub-10 ns current rise times require equally fast diode response to clamp before voltage overshoot exceeds IC tolerance limits.
