Product details
Overview
BAV99TE6327 from Infineon Technologies is a silicon dual-series switching diode in SOT-363 (SC-74) package, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time, used in high-speed polarity protection and signal clamping circuits in automotive body control modules.
For engineers reviewing the BAV99TE6327 datasheet, BAV99TE6327 pinout, BAV99TE6327 application, or BAV99TE6327 equivalent, key selection criteria include reverse recovery time under 4 ns, dual-series configuration for bidirectional clamping, thermal resistance ≤260 K/W, and AEC-Q101 qualification for automotive use.
Technical Context
This dual-diode device integrates two identical high-speed switching diodes in series within a single SOT-363 package, enabling symmetrical clamping across signal lines without external biasing. Its low 1.5 pF capacitance at 0 V and fast 4 ns trr support >100 MHz digital interface protection.
The device operates with a maximum junction temperature of 150 °C and is qualified to AEC-Q101, confirming robustness against thermal cycling and mechanical stress in automotive under-hood environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 (Nexperia) | Same SOT-323 package; RthJS = 160 K/W; VF = 1.25 V @ 150 mA | Higher thermal performance enables higher continuous current in space-constrained layouts | Select when PCB area allows SOT-323 and thermal budget requires <160 K/W |
| MMBD99DW-7-F (Diodes Inc.) | SOT-363 package; trr = 6 ns; IR = 0.1 µA @ 70 V; VF = 1.25 V @ 150 mA | Slower recovery limits use to ≤50 MHz signals but offers lower leakage for precision analog paths | Select when ultra-low IR (<0.15 µA) is prioritized over speed in sensor front-ends |
Compared with BAV99TE6327, BAV99W offers better thermal dissipation in smaller footprint but lacks AEC-Q101 validation, while MMBD99DW-7-F trades 2 ns slower recovery for 3× lower leakage-critical in battery-powered sensor nodes.

FAQ
What is the pin 1 marking method for BAV99TE6327?
Pin 1 is identified by a small dot or bevelled corner on the top surface of the SOT-363 package, located adjacent to lead 1. The marking conforms to JEDEC MO-178 standards and is laser-etched for permanent identification during automated optical inspection.
Does BAV99TE6327 support bidirectional ESD protection?
Yes - its dual-series configuration provides symmetrical clamping: one diode conducts positive transients to VCC, the other conducts negative transients to GND, achieving ±15 kV contact ESD protection per IEC 61000-4-2 when used with appropriate series impedance.
Can BAV99TE6327 replace single-diode packages like BAV99 in existing designs?
No - BAV99TE6327 is a dual-series device in SOT-363, whereas standard BAV99 is single-diode in SOT-23. Direct replacement requires schematic and layout revision to accommodate the 6-pin footprint and series topology.
Is thermal derating required above 85°C ambient?
Yes - the datasheet specifies Ptot = 250 mW only when TS ≤ 85°C. Above that, power must be linearly derated at 3.1 mW/°C based on RthJS ≤ 260 K/W, reaching zero dissipation at 165°C case temperature.
