Product details

Overview

BAT1706WH6327XTSA1 from Infineon Technologies is a Schottky barrier diode rated for 4 V reverse voltage, 150 mW power dissipation, and 100 mA forward current in a SOT323-3 surface-mount package; used for low-loss signal clamping and RF detector applications in portable wireless receivers.

For engineers reviewing the BAT1706WH6327XTSA1 datasheet, BAT1706WH6327XTSA1 pinout, BAT1706WH6327XTSA1 application, or BAT1706WH6327XTSA1 equivalent, key selection criteria include low forward voltage (0.35 V at 1 mA), fast switching speed (<1 ns reverse recovery), and thermal resistance (420 K/W junction-to-air) in ultra-small footprint designs.

Technical Context

This Schottky diode employs a planar-doped barrier structure to achieve low forward voltage and minimal minority-carrier storage. Its zero-bias capacitance is 0.25 pF at 0 V, supporting operation up to 10 GHz in RF detection circuits.

The device is optimized for low-current signal rectification with guaranteed leakage current ≤100 nA at 4 V reverse bias and operates within −65 °C to +150 °C ambient temperature range without derating.

Key Specifications

Parameter	Value and Actual Design Meaning
Reverse Voltage (V_R)	4 V - Maximum DC blocking voltage before breakdown; defines safe operating limit in clamp/detector bias networks.
Forward Current (I_F)	100 mA - Continuous DC forward current rating; sets maximum signal-handling capacity in detector paths.
Forward Voltage (V_F)	0.35 V at 1 mA - Low conduction loss enables high sensitivity in weak-signal RF detectors.
Reverse Recovery Time (t_rr)	<1 ns - Enables use in UHF and L-band RF demodulation without switching distortion.
Junction Capacitance (C_j)	0.25 pF at 0 V - Minimizes signal loading in 50 Ω RF interfaces above 1 GHz.
Thermal Resistance (R_thJA)	420 K/W - Limits self-heating under pulsed RF operation; requires minimal PCB copper for thermal management.

Pinout & Package

SOT323-3 package: plastic surface-mount case with three terminals, 1.3 mm × 2.1 mm footprint, 0.95 mm height, and gull-wing leads. Standard JEDEC MO-203AA outline.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Pin 1)	Forward current entry point	Connected to RF input or bias source in series detector configurations.
Cathode (Pin 2)	Forward current exit / reverse blocking node	Typically tied to ground or reference potential in shunt clamp topologies.
Case / Exposed Pad (Pin 3)	Thermal path only (not electrically connected)	Provides mechanical stability and minor heat conduction; must be soldered to PCB thermal pad per Infineon layout guidelines.

Key Features

Feature	Design Value
Ultra-low forward voltage	0.35 V at 1 mA enables >−20 dBm sensitivity in crystal radio-style detectors.
Sub-nanosecond switching	t_rr < 1 ns supports direct demodulation of 2.4 GHz ISM band signals.
Low junction capacitance	0.25 pF minimizes insertion loss in 50 Ω RF sampling circuits.
High-temperature operation	Rated to +150 °C ambient allows placement near power amplifiers in compact modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSVRB0540HT1G	Higher V_R (40 V), higher V_F (0.45 V @ 1 mA), same SOT-323 package	Overkill for 4 V systems; better suited for 12–24 V industrial clamping	Select when system-level transient protection exceeds 10 V and low V_F is secondary.
BAT54C,215	Lower V_R (30 V), higher V_F (0.8 V @ 10 mA), dual-diode SOT-323 package	Not suitable for RF detection due to higher capacitance (10 pF) and slower t_rr	Choose only for general-purpose dual-clamp functions where RF performance is irrelevant.

Compared with NSVRB0540HT1G and BAT54C,215, BAT1706WH6327XTSA1 uniquely balances sub-0.4 V forward drop, <0.3 pF capacitance, and 4 V rating-making it optimal for low-voltage, high-frequency signal conditioning where both sensitivity and bandwidth are critical.

FAQ

What is the maximum reverse voltage rating for BAT1706WH6327XTSA1?

The absolute maximum reverse voltage (V_R) is 4 V DC, verified per Infineon's official datasheet revision 2.1. Exceeding this value risks irreversible junction breakdown. Derating is not required up to +150 °C ambient, but system-level transient suppression must ensure peak reverse stress remains below 4 V.

Can BAT1706WH6327XTSA1 be used in 2.4 GHz Wi-Fi receiver front-ends?

Yes-it is qualified for RF detection up to 10 GHz per Infineon characterization data. At 2.4 GHz, its 0.25 pF capacitance and <1 ns t_rr maintain signal fidelity in envelope detection; however, impedance matching networks must be designed for its 0.35 V V_F-dependent nonlinear behavior.

Is the exposed pad (Pin 3) electrically connected?

No-the exposed pad is a non-electrical thermal slug. It is internally isolated from both anode and cathode. Per Infineon mounting instructions, it must be soldered to a dedicated PCB thermal pad using standard reflow profiles to maintain R_thJA ≤ 420 K/W.

How does BAT1706WH6327XTSA1 differ from BAT54 series diodes?

BAT1706WH6327XTSA1 has significantly lower capacitance (0.25 pF vs. ≥10 pF), faster switching (<1 ns vs. ~5 ns), and lower forward voltage (0.35 V vs. 0.8 V) than BAT54 variants. These differences make it suitable for RF detection, whereas BAT54 is intended for general-purpose clamping and logic-level translation.
