Infineon Technologies BAV70UE6327HTSA1

Overview

BAV70UE6327HTSA1 from Infineon Technologies is a silicon switching diode in SOT363 (SC74) package with common-cathode dual configuration, 80 V reverse voltage rating, 200 mA forward current, and 4 ns reverse recovery time - used for high-speed signal routing and clamping in automotive body control modules.

For engineers reviewing the BAV70UE6327HTSA1 datasheet, BAV70UE6327HTSA1 pinout, BAV70UE6327HTSA1 application, or BAV70UE6327HTSA1 equivalent, this part supports AEC-Q101-qualified designs requiring fast switching, low capacitance (1.5 pF), and thermal robustness up to 150 °C junction temperature.

Technical Context

This dual common-cathode diode integrates two independent high-speed switching elements sharing one cathode terminal, enabling compact bidirectional clamping or logic-level steering. Its 1.5 pF capacitance at 0 V and 4 ns trr support >100 MHz signal integrity in data line protection circuits.

The device operates across –65 °C to +150 °C storage range and sustains 85 V breakdown voltage at 100 µA test current. Thermal resistance from junction to soldering point is ≤260 K/W, validated for SOT363 mounting on standard FR-4 PCBs with 25 mm² copper pad.

FAQ

What is the maximum allowable peak reverse voltage for BAV70UE6327HTSA1?

The absolute maximum peak reverse voltage (VRM) is 85 V, measured under pulsed conditions. The rated DC reverse voltage (VR) is 80 V - exceeding this value risks irreversible breakdown. This rating is validated per AEC-Q101 stress testing and applies across the full operating temperature range (–65 °C to +150 °C).

Is BAV70UE6327HTSA1 suitable for bidirectional ESD protection on differential pairs?

Yes - its common-cathode dual configuration allows symmetrical clamping of both signal lines to a shared reference (e.g., VCC or ground). With 1.5 pF capacitance and matched 4 ns trr, it preserves signal skew and eye diagram integrity in USB 2.0 and CAN FD differential channels without introducing imbalance.

How does the thermal performance of BAV70UE6327HTSA1 compare to single-diode SOT23 equivalents?

Its RthJS of ≤260 K/W (junction-to-soldering-point) is 18% lower than typical SOT23 dual-diode alternatives due to the SC74 package's larger copper slug and dual thermal paths. This enables 200 mA continuous operation at 85 °C board temperature - whereas comparable SOT23 parts derate to 150 mA under identical conditions.

Can BAV70UE6327HTSA1 replace BAV70S in existing designs?

Yes, with layout verification: both use SOT363 and share identical pinout and electrical specs, but BAV70UE6327HTSA1 is the tape-and-reel variant (E6327) with HTSA1 marking, qualified to AEC-Q101 Rev D. No schematic or firmware changes are needed - only ensure reel orientation matches the pick-and-place machine's vision calibration for Pin 1 detection.
