Product details
Overview
BAV99TE6433 from Nexperia is a silicon dual-series switching diode in SOT363 (SC74) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-designed for high-speed signal routing and ESD protection in automotive CAN bus interface circuits.
For engineers reviewing the BAV99TE6433 datasheet, BAV99TE6433 pinout, BAV99TE6433 application, or BAV99TE6433 equivalent, this device serves as a fast-switching dual-diode pair with AEC-Q101 qualification, low capacitance (1.5 pF), and thermal robustness up to 150 °C junction temperature.
Technical Context
The BAV99TE6433 integrates two identical silicon PN junction diodes in series configuration within a single SOT363 package, enabling bidirectional clamping and polarity-insensitive signal steering. Its 4 ns trr and 1.5 pF CT support >100 MHz signal integrity in data line protection.
Thermal design is enabled by RthJS ≤ 260 K/W (BAV99S variant), with derated forward current curves validated across -65 °C to +150 °C ambient, and AEC-Q101 qualification confirming suitability for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 10–50 MHz digital signal paths and CAN FD interfaces |
| Diode Capacitance (CT) | 1.5 pF @ 0 V - minimizes signal loading on high-speed I²C, USB, or LIN bus lines |
| Forward Current (IF) | 200 mA DC - sufficient for logic-level clamping and low-power ESD current shunting |
| Junction Temperature (Tj) | 150 °C - meets AEC-Q101 requirement for under-hood automotive electronics |
| Thermal Resistance (RthJS) | ≤260 K/W - allows 250 mW power dissipation at TS ≤ 85 °C in PCB-constrained layouts |
Pinout & Package
SOT363 (SC74) surface-mount package: 6-pin, dual-row, 0.65 mm pitch, 2.1 × 2.0 × 1.0 mm body height, tape-and-reel packaging (3,000 pcs/reel, ø180 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | Input node for unidirectional clamping or series switching path |
| 2 | Cathode of Diode 1 / Anode of Diode 2 | Shared internal node enabling series diode configuration |
| 3 | Cathode of Diode 2 | Output/return node; connects to ground or reference rail in clamp topology |
| 4 | No Connect (NC) | Internally isolated; must be left floating or tied to GND per layout best practice |
| 5 | No Connect (NC) | Internally isolated; no electrical function; avoid routing signals to this pad |
| 6 | No Connect (NC) | Internally isolated; mechanical anchor only; no circuit role |

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 (Nexperia) | SOT323 package (smaller footprint), same electrical specs, RthJS ≤ 160 K/W | Better thermal performance in space-constrained layouts; lower profile for low-height assemblies | Select when board real estate is limited and thermal margin above 85 °C is required |
| MMBD7000LT1G (onsemi) | SOT23-3 package, single-diode dual-anode configuration, VF = 1.25 V @ 150 mA | Not series-configured; requires external bias for bidirectional clamping; higher VF increases conduction loss | Choose only if redesign permits discrete diode placement and higher forward drop is acceptable |
Compared with BAV99TE6433, the BAV99W offers superior thermal resistance in a smaller package but lacks reel orientation marking; the MMBD7000LT1G provides comparable speed but requires additional components to replicate series-clamp functionality.

FAQ
What is the pin 1 marking convention for BAV99TE6433 in SOT363 tape?
Pin 1 is marked by a small dot or notch adjacent to lead 1 on the top surface of the SOT363 package. Per Nexperia package drawing SC74, the marking is laser-etched near the corner of the die pad; orientation in reel is not defined for symmetric types, so board layout must rely on physical package marking-not reel direction.
Does BAV99TE6433 support bidirectional ESD protection without external bias?
Yes. Its internal dual-series configuration (Anode–Cathode–Anode–Cathode) forms a symmetrical clamp path between any two terminals, enabling bidirectional transient suppression on differential lines like CAN or USB without external voltage rails or bias resistors.
How does the 4 ns reverse recovery time impact 100 Mbps serial link performance?
A 4 ns trr limits minimum pulse width to ~10 ns, supporting clean edge transmission in protocols up to 100 Mbps. Measured under IF = IR = 10 mA conditions, it ensures <0.5% duty-cycle distortion on NRZ-encoded signals, preserving jitter budgets in CAN FD and LIN physical layers.
Is BAV99TE6433 compatible with lead-free reflow profiles per JEDEC J-STD-020?
Yes. The device is qualified for Pb-free assembly using standard SnAgCu reflow profiles (peak 260 °C, 20–40 sec above 217 °C). Its SOT363 package passes MSL-1 rating, and the die attach and wire bond systems are fully compatible with lead-free soldering processes.
