Product details
Overview
BAV99W H6327 from Infineon Technologies is a dual series-connected silicon switching diode in SOT-323 (SC74) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, used in high-speed signal clamping and ESD protection circuits in automotive infotainment and industrial sensor interfaces.
For engineers reviewing the BAV99W H6327 datasheet, BAV99W H6327 pinout, BAV99W H6327 application, or BAV99W H6327 equivalent, key selection criteria include its 1.5 pF diode capacitance at 0 V, 1.25 V forward voltage at 150 mA, AEC-Q101 qualification, RoHS-compliant lead-free construction, and thermal resistance of 160 K/W junction-to-soldering-point.
Technical Context
The BAV99W integrates two identical high-speed switching diodes in series configuration within a single SOT-323 package, enabling bidirectional clamping without external biasing. Its 4 ns trr and low 1.5 pF CT support operation up to ~200 MHz in RF front-end protection and data line transient suppression.
Designed for automotive-grade reliability, it meets AEC-Q101 stress testing requirements and operates across –65 °C to +150 °C storage temperature range with 250 mW total power dissipation at TS ≤ 110 °C, leveraging its 160 K/W RthJS for stable thermal performance in space-constrained PCB layouts.

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) | Identical SOT-323 package, same 80 V VR and 4 ns trr, but 200 mW Ptot rating at TS ≤ 105 °C | Lower thermal margin in high-ambient environments; requires tighter board-level thermal design | Select when sourcing flexibility is prioritized over extended thermal headroom |
| MMBD7000LT1G (onsemi) | Same dual-series topology but 100 V VR, 3 ns trr, and 225 mW Ptot at TS ≤ 110 °C | Better surge handling for 48 V systems; slightly higher VF (1.25 V @ 100 mA vs. 1.2 V @ 100 mA) | Prefer for industrial 48 V DC-powered equipment requiring higher reverse standoff |
Compared with BAV99W H6327, the Nexperia variant trades 5 °C thermal margin for broader distribution availability, while the onsemi part offers higher VR and faster trr at minor VF cost-making it suitable for next-generation 48 V platforms where clamping speed and voltage headroom outweigh absolute leakage minimization.

FAQ
What is the pin 1 marking convention for BAV99W H6327?
Pin 1 is marked by a small dot or notch located near the left edge of the SOT-323 package top surface, aligned with the anode of the first diode. The device uses standard SC74 orientation: viewing the top side with marking toward the viewer, Pin 1 is bottom-left, Pin 2 center, Pin 3 bottom-right.
Does BAV99W H6327 support bidirectional ESD protection without external bias?
Yes - its internal dual-series configuration forms a symmetrical clamping structure between Pins 1 and 3, allowing ±15 kV IEC 61000-4-2 ESD current diversion in both directions without external resistors or voltage references.
How does thermal resistance differ between BAV99W and BAV99S variants?
BAV99W has RthJS ≤ 160 K/W at TS ≤ 110 °C, while BAV99S is rated ≤ 260 K/W at TS ≤ 85 °C. This reflects optimized die attach and package layout in the W-variant, delivering 38% lower thermal resistance for equivalent power dissipation.
Can BAV99W H6327 replace discrete 1N4148 diodes in high-frequency circuits?
No - although electrically similar, BAV99W's series-connected dual-diode topology creates a fixed 2× forward voltage drop and lacks independent cathode/anode access. It is not a drop-in replacement for two separate 1N4148s unless the circuit explicitly requires series clamping behavior.
