Infineon Technologies BAT6806WH6327XTSA1

Overview

BAT6806WH6327XTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common-anode dual diode pair in SOT323 package, rated for 8 V reverse voltage, 130 mA forward current, and optimized for VHF/UHF mixer and high-speed switching applications with 1.4 nH series inductance and 1 pF capacitance at 0 V.

For engineers reviewing the BAT6806WH6327XTSA1 datasheet, BAT6806WH6327XTSA1 pinout, BAT6806WH6327XTSA1 application, or BAT6806WH6327XTSA1 equivalent, this part supports RF signal routing, low-loss detector circuits, and fast-switching bias networks where low forward voltage (340 mV typ. @ 1 mA), minimal junction capacitance, and thermal robustness (Tj = 150 °C) are critical.

Technical Context

This dual-diode configuration enables balanced mixing and phase-sensitive detection in RF front-ends. Its common-anode topology allows shared biasing while maintaining independent cathode paths, supporting push-pull or differential signal handling up to UHF frequencies.

The device exhibits low differential forward resistance (10 Ω typ. @ 5 mA, 10 kHz) and tight capacitance-voltage tracking (CT ≤ 1 pF @ VR = 0 V, f = 1 MHz), making it suitable for low-distortion envelope detection and local oscillator injection circuits.

FAQ

What is the maximum operating frequency for BAT6806WH6327XTSA1 in mixer applications?

The device is characterized for VHF/UHF use up to 1 GHz, with verified performance in 433 MHz and 900 MHz mixer circuits. Its 1 pF capacitance and 10 Ω RF resistance support usable bandwidth beyond 1.5 GHz, though conversion loss increases above 1.2 GHz due to series inductance effects.

Can BAT6806WH6327XTSA1 be used in series or parallel configurations beyond its common-anode design?

No - the internal common-anode structure fixes the anode connection; external series or parallel use would short cathodes or violate bias constraints. For alternative topologies, select BAT68-04 (series) or BAT68-08S (parallel triple) variants explicitly designed for those configurations.

Is thermal derating required for continuous 130 mA operation?

Yes - full 130 mA rating assumes junction temperature ≤150 °C and board-level thermal resistance ≤590 K/W. At ambient >60 °C or with minimal copper area, current must be reduced per the IF vs. TS curves in Infineon's BAT68-06W datasheet Figure 5.

Does the "H6327" suffix indicate tape-and-reel packaging or a process revision?

H6327 denotes Infineon's standard 3,000-piece 180 mm reel packaging with humidity-sensitive level 1 (MSL1) handling; it is not a process revision code. The "XTSA1" suffix confirms RoHS-compliant matte tin termination and full traceability per JEDEC J-STD-020.
