Product details
Overview
BAT17E6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a parallel pair in SOT143 package, rated for 4 V reverse voltage, 130 mA forward current, and optimized for VHF/UHF mixer applications with 0.55 pF typical capacitance at 1 MHz and 8 Ω differential forward resistance at 5 mA. It supports high-speed switching in RF front-ends and meets AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BAT17E6327HTSA1 datasheet, BAT17E6327HTSA1 pinout, BAT17E6327HTSA1 application, or BAT17E6327HTSA1 equivalent, key selection criteria include its parallel-pair configuration, low junction-to-soldering-point thermal resistance (≤390 K/W), tight forward voltage matching (≤20 mV at 1 mA), and specified performance across -55 °C to 125 °C operating range.
Technical Context
This Schottky diode operates as a dual-element parallel pair - both anodes connected internally, cathodes isolated - enabling balanced signal handling in passive mixer topologies. Its 0.55 pF capacitance and 8 Ω dynamic resistance at 10 kHz support stable impedance matching up to 1 GHz.
The device uses platinum-silicide barrier technology for low forward voltage and fast recovery, with junction temperature limited to 150 °C and thermal resistance optimized for SOT143's four-terminal layout. Reverse leakage stays below 10 µA at 4 V and 25 °C, critical for low-noise RF detection.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode (common) | Shared RF input node for both diode elements; connects to local oscillator or RF port in mixer design |
| Pin 2 | Cathode 1 | First output path for IF or RF signal routing; enables differential current steering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-03W | Single Schottky in SOT323; 0.45 pF CT, 100 mA IF rating | Lacks parallel-pair configuration; requires external pairing for balanced mixing | Preferred where board space is constrained and single-ended LO injection is acceptable |
| BAT17-06W | Common-anode dual in SOT323; 0.55 pF CT, 130 mA IF, but RthJS = 590 K/W | Same electrical specs but higher thermal resistance limits continuous RF power handling | Acceptable for intermittent-duty receivers but not for high-duty-cycle transceivers |
Compared with BAR63-03W and BAT17-06W, BAT17E6327HTSA1 delivers superior thermal performance (≤390 K/W) and guaranteed matched-pair operation in a single SOT143 package - critical for production-stable mixer conversion loss and phase balance.

FAQ
What is the pin 1 marking convention for BAT17E6327HTSA1?
Pin 1 is identified by a molded dot or notch on the SOT143 package body, located adjacent to the lead edge closest to the common anode terminals (Pins 1 and 4). The marking "57s" appears on the top surface, consistent with Infineon's BAT17-07 variant coding per the 2007 datasheet revision.
Does BAT17E6327HTSA1 support DC biasing in active mixer configurations?
No - BAT17E6327HTSA1 is a passive Schottky diode intended for zero-bias or low-bias mixer/detector use. It lacks integrated bias circuitry or active transistor elements; DC bias must be applied externally via RF chokes or bias tees, respecting its 4 V VR and 130 mA IF limits.
How does the parallel-pair configuration affect impedance matching?
The internal parallel-pair structure halves the effective junction capacitance and dynamic resistance versus a single diode, yielding ~0.275 pF and ~4 Ω equivalent values - simplifying 50 Ω microstrip matching network design and reducing harmonic generation in fundamental-mode mixers.
Is BAT17E6327HTSA1 compatible with lead-free reflow profiles?
Yes - it is RoHS-compliant and qualified for standard Pb-free reflow per JEDEC J-STD-020, with peak temperature tolerance up to 260 °C for 10 seconds. The SOT143 package withstands thermal cycling without solder joint cracking or parameter shift beyond specification limits.
