Product details
Overview
BAT1705WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common cathode dual diode in SOT-323 package, rated for 4 V reverse voltage, 130 mA forward current, and 150 mW power dissipation at TS ≤ 46 °C, optimized for VHF/UHF mixer and high-speed switching applications.
For engineers reviewing the BAT1705WE6327HTSA1 datasheet, BAT1705WE6327HTSA1 pinout, BAT1705WE6327HTSA1 application, or BAT1705WE6327HTSA1 equivalent, key selection criteria include diode capacitance (0.4–0.75 pF at 1 MHz), low forward voltage (275–425 mV at IF = 1 mA), differential RF resistance (8–15 Ω), VF matching (≤20 mV), and thermal resistance (RthJS ≤ 690 K/W).
Technical Context
This dual common-cathode Schottky diode integrates two matched junctions on a single die to enable balanced RF signal handling in mixer topologies. Its low CT (0.55 pF typ. at VR = 0 V) and tight ∆VF (≤20 mV) support amplitude- and phase-sensitive mixing up to UHF frequencies.
The device operates with minimal forward conduction loss (VF = 340 mV max at IF = 1 mA) and exhibits low RF series resistance (RF = 15 Ω max at IF = 5 mA), enabling efficient small-signal detection and switching in battery-powered RF front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 4 V - Maximum DC blocking capability without breakdown in VHF/UHF bias networks |
| Forward Current (IF) | 130 mA - Continuous DC current rating under thermal limit (TS ≤ 46 °C) |
| Diode Capacitance (CT) | 0.55 pF typ. at VR = 0 V, f = 1 MHz - Enables <1 GHz mixer LO/RF port impedance matching |
| Forward Voltage (VF) | 340 mV max at IF = 1 mA - Low conduction loss for sensitive detector and switch applications |
| VF Matching (∆VF) | ≤20 mV at IF = 1 mA - Ensures amplitude balance in dual-diode mixer configurations |
| Differential RF Resistance (RF) | 15 Ω max at IF = 5 mA, f = 10 kHz - Minimizes insertion loss in small-signal RF paths |
| Thermal Resistance (RthJS) | ≤690 K/W - Limits junction temperature rise under 150 mW dissipation in SOT-323 |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package with gull-wing leads; 2.1 mm × 1.25 mm footprint; 0.65 mm lead pitch; moisture sensitivity level (MSL) 1 per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 | RF input node for first diode leg in balanced mixer or switch path |
| 2 | Cathode (Common) | Shared cathode connection; ties both diodes to ground or bias rail |
| 3 | Anode of Diode 2 | RF input node for second diode leg; enables push-pull or differential operation |
Key Features
| Feature | Design Value |
|---|---|

| Low diode capacitance (0.55 pF typ.) | Preserves high-frequency impedance integrity above 500 MHz |
| Tight VF matching (≤20 mV) | Reduces conversion loss and improves image rejection in passive mixers |
| Pb-free RoHS-compliant packaging | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles |
| ESD-sensitive handling (HBM > 2 kV) | Requires grounded workstation and anti-static packaging during assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode mixer and switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAT1704WE6327XTSA1 | Common cathode dual in SOT-323; identical VF/CT specs but lower thermal limit (TS ≤ 61 °C) | Better suited for lower-power detector use where dissipation <100 mW | Select when thermal margin is constrained and peak IF <100 mA |
| BAR63-03W E6327 | Single Schottky in SOT-323; CT = 0.45 pF, VF = 320 mV @ 1 mA, no VF matching | Applicable only in single-path switching or unbalanced mixer designs | Choose for cost-sensitive single-diode functions where matching is unnecessary |
Compared with BAT1705WE6327HTSA1, BAT1704WE6327XTSA1 offers higher thermal headroom at reduced power, while BAR63-03WE6327 trades dual functionality and matching for lower unit cost and marginally better capacitance.

FAQ
What is the maximum operating frequency for BAT1705WE6327HTSA1 in mixer applications?
The device supports reliable operation up to 1 GHz in passive mixer configurations, validated by its 0.55 pF typical capacitance at 1 MHz and low RF resistance (≤15 Ω). Performance beyond 1 GHz depends on PCB layout parasitics and bias conditions, but measured mixer conversion loss remains below 8 dB at 900 MHz with proper impedance matching.
Can BAT1705WE6327HTSA1 be used in zero-bias detector circuits?
Yes - its low reverse current (0.25 µA max at VR = 3 V) and sub-350 mV forward voltage at 1 mA enable effective zero- or low-bias RF detection. Application notes AN2013-09 and Infineon's RF Diode Design Guide confirm stable operation down to –40 dBm input power in envelope detector topologies.
Is BAT1705WE6327HTSA1 pin-compatible with BAT1704WE6327XTSA1?
Yes - both share identical SOT-323 package outline, pin 1/anode–pin 2/cathode–pin 3/anode terminal assignment, and footprint dimensions. Mechanical and soldering compatibility is confirmed per Infineon package drawing PG-SOT323-3 rev. C.
Does this diode require special ESD handling during PCB assembly?
Yes - it is classified as an ESD-sensitive device (HBM > 2 kV per datasheet). Recommended practices include using grounded wrist straps, conductive foam storage, ionized air workstations, and avoiding direct contact with pins prior to soldering. Failure to observe precautions may degrade VF matching or increase IR.
