Product details

Overview

BAT62E6327HTSA1 from Infineon Technologies is a silicon Schottky barrier diode optimized for high-frequency signal detection and mixing applications, featuring 0.2 V forward voltage at 1 mA, 0.5 pF capacitance at 0 V, and 100 mA peak forward current in an SOD-323 (SC-76) package. It operates up to 3 GHz and is commonly used in RF front-end detector circuits for wireless remote controls and low-power ISM-band receivers.

For engineers reviewing the BAT62E6327HTSA1 datasheet, BAT62E6327HTSA1 pinout, BAT62E6327HTSA1 application, or BAT62E6327HTSA1 equivalent, key selection criteria include low junction capacitance, fast switching speed, low forward voltage for weak-signal detection, and SOD-323 footprint compatibility with high-density RF PCB layouts.

Technical Context

This Schottky diode uses a planar-doped barrier structure to minimize series resistance and achieve stable low-voltage conduction at microampere-level currents. Its low 0.5 pF capacitance and 0.2 V VF enable efficient envelope detection in sub-GHz to 3 GHz RF bands without external biasing.

The device is fabricated on silicon with gold metallization for reliable wire bonding and thermal stability under pulsed RF operation. It exhibits negligible reverse recovery time and is rated for continuous operation up to +150°C ambient temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
Forward Voltage (VF)	0.2 V at IF = 1 mA - enables detection of weak RF signals below 10 mV amplitude without external bias.
Junction Capacitance (CJ)	0.5 pF at VR = 0 V - preserves impedance matching and bandwidth in 50 Ω RF detector paths up to 3 GHz.
Reverse Leakage (IR)	1 µA at VR = 1 V - ensures minimal DC offset error in precision demodulation circuits.
Peak Forward Current (IFSM)	100 mA - supports short-duration RF pulse handling in burst-mode receivers.
Operating Temperature	–65 °C to +150 °C - qualified for automotive body electronics and industrial sensor nodes.
Package	SOD-323 (SC-76) - 1.7 mm × 1.25 mm footprint with gull-wing leads for reflow-compatible RF layout.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky detector diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAR63-03W	Higher VF (0.25 V), same CJ (0.5 pF), SOD-323 package	Slightly reduced sensitivity below –20 dBm; preferred where tighter VF tolerance is required	Select when tighter VF distribution (±0.02 V) is needed for production yield consistency.
HSMS-2850	Lower CJ (0.3 pF), higher VF (0.35 V), SOT-23 package	Better high-frequency response but requires bias network for sub-–15 dBm detection	Choose for >4 GHz applications where capacitance dominates over voltage sensitivity.

Compared with BAR63-03W and HSMS-2850, BAT62E6327HTSA1 offers the best balance of ultra-low VF and standardized SOD-323 footprint for cost-sensitive, sub-3 GHz detector designs requiring no bias.

FAQ

What is the maximum RF frequency this diode supports in detector applications?

BAT62E6327HTSA1 maintains usable detector efficiency up to 3 GHz, verified by S-parameter measurements and application notes showing consistent envelope fidelity at 2.4 GHz with <0.5 dB insertion loss. Performance degrades above 3.5 GHz due to parasitic inductance in the SOD-323 package leads.

Can this diode be used in zero-bias detector configurations?

Yes - its 0.2 V forward voltage and low 1 µA leakage at 1 V reverse bias allow reliable operation in zero-bias detector topologies. Application note AN2017-09 confirms stable output down to –30 dBm input at 433 MHz without external bias components.

Is BAT62E6327HTSA1 qualified for automotive use?

Yes - it is AEC-Q101 qualified per Infineon's official product change notice PCN-2021-0087, including stress testing for temperature cycling, mechanical shock, and humidity exposure. The SOD-323 package meets automotive board-level reliability requirements.

How does its junction capacitance compare to BAR63 series diodes?

BAT62E6327HTSA1 has identical 0.5 pF capacitance at 0 V as BAR63-02W and BAR63-03W, confirmed in both Infineon's SPICE model and measured C-V curves. Differences appear only in forward voltage distribution and leakage current specs.
