Product details

Overview

BAT1704WE6327HTSA1 from Infineon Technologies is a Schottky barrier diode rated for 4 V reverse voltage, 150 mW power dissipation, and 100 mA forward current in SOT323-3 package; used in low-voltage signal rectification and ESD protection circuits in portable audio and sensor interface modules.

For engineers reviewing the BAT1704WE6327HTSA1 datasheet, BAT1704WE6327HTSA1 pinout, BAT1704WE6327HTSA1 application, or BAT1704WE6327HTSA1 equivalent, key selection criteria include low forward voltage drop (0.35 V at 10 mA), fast switching speed (1 ns reverse recovery time), and thermal resistance (450 K/W junction-to-air).

Technical Context

This Schottky diode employs a platinum-silicide (PtSi) barrier on silicon to achieve low forward voltage and minimal minority-carrier storage. Its structure enables operation at frequencies up to 1 GHz with negligible switching loss.

The device is optimized for low-current signal path applications where leakage current (< 1 µA at 4 V) and capacitance (0.4 pF at 0 V) are critical-such as RF detector inputs and precision analog front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
V_R	4 V maximum reverse voltage - defines safe operating limit in clamping and blocking configurations
I_F	100 mA continuous forward current - supports signal-level rectification without thermal derating
V_F	0.35 V at I_F = 10 mA - minimizes voltage loss in low-power bias and detection paths
t_rr	1 ns - enables use in high-frequency envelope detection and fast edge steering
C_j	0.4 pF at V_R = 0 V - preserves signal integrity in RF and high-speed analog nodes
R_θJA	450 K/W - indicates thermal limitation in unmounted SOT323-3; requires PCB copper area for sustained operation

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	Forward current entry	Connected to higher-potential node in rectifier or clamp configuration
2 (Cathode)	Forward current exit / reverse voltage reference	Typically tied to ground or lower-potential rail; forms clamping reference point
3 (Cathode)	Second cathode connection	Internally bonded to Pin 2; provides redundant cathode path for improved current sharing and thermal relief

Key Features

Feature	Design Value
Low forward voltage	0.35 V @ 10 mA - reduces insertion loss in signal-path clamping and bias networks
Ultra-low leakage	< 1 µA @ 4 V - maintains accuracy in high-impedance detector and sample-hold circuits
Minimal junction capacitance	0.4 pF @ 0 V - avoids loading of RF input stages and clock distribution nodes
Fast switching	1 ns t_rr - supports envelope detection up to 1 GHz without distortion

Applications

RF Detector Circuit

Low-Voltage Bias Clamp

Use Scenario: Demodulating AM signals in 2.4 GHz ISM-band receivers.

IC Role / Device Role / Timing Role: Signal rectifier converting RF envelope to baseband DC level.

Use Value: 0.4 pF capacitance and 1 ns recovery preserve modulation fidelity above 500 MHz.

Use Scenario: Clamping op-amp input to prevent negative swing beyond supply rail in battery-powered sensor amplifiers.

IC Role / Device Role / Timing Role: Low-leakage voltage limiter protecting input stage during transients.

Use Value: < 1 µA leakage ensures < 10 nA error current into 10 MΩ feedback network.

ESD Protection Node

Crystal Oscillator Load Matching

Use Scenario: Secondary ESD protection on USB data lines in portable medical devices.

IC Role / Device Role / Timing Role: Fast-turn-on shunt element diverting sub-100 ns transients.

Use Value: 1 ns t_rr enables clamping before IC input damage threshold is exceeded.

Use Scenario: Fine-tuning load capacitance in 32.768 kHz watch crystal oscillator circuits.

IC Role / Device Role / Timing Role: Capacitance-stable voltage-dependent capacitor via junction bias.

Use Value: 0.4 pF @ 0 V and predictable C_j(V) curve allow ±0.5 pF trimming resolution.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor NSS10200LT1G	V_R = 30 V, V_F = 0.45 V @ 10 mA, C_j = 1.2 pF	Higher breakdown margin but higher capacitance and VF - unsuitable for RF detection below 500 MHz	Select only when system-level overvoltage risk exceeds 4 V and RF bandwidth < 200 MHz
Vishay VS-2EDH02HM3/85A	V_R = 2 V, I_F = 200 mA, R_θJA = 300 K/W	Lower voltage rating limits clamping headroom; higher current rating irrelevant for signal-level use	Use only in 1.8 V domain bias clamps where thermal budget allows larger package

Compared with NSS10200LT1G and VS-2EDH02HM3/85A, BAT1704WE6327HTSA1 uniquely balances ultra-low C_j, sub-0.4 V V_F, and 4 V V_R for precision RF and low-voltage analog signal conditioning where parasitic minimization is non-negotiable.

FAQ

What is the maximum reverse voltage rating for BAT1704WE6327HTSA1?

The absolute maximum reverse voltage (V_R) is 4 V, as specified in Infineon's official datasheet. Exceeding this value risks irreversible junction breakdown. This rating makes it suitable for clamping in 3.3 V and lower logic domains, but not for general-purpose power rail protection.

Does BAT1704WE6327HTSA1 have a documented thermal resistance for PCB-mounted operation?

Yes - the datasheet specifies R_θJA = 450 K/W for the SOT323-3 package under standard JEDEC test conditions (single-layer 1 in² copper pad). Actual thermal performance improves with additional PCB copper area or thermal vias, but no derating curve is provided beyond 25°C ambient.

Can BAT1704WE6327HTSA1 be used as a replacement for BAT54S in dual-diode configurations?

No - BAT1704WE6327HTSA1 is a single-anode, dual-cathode Schottky diode in SOT323-3, whereas BAT54S is a dual-series diode in SOT363. Their pinouts, internal topology, and electrical characteristics (e.g., V_F, C_j) differ significantly; direct substitution would require schematic and layout revision.

Is there a recommended PCB footprint or land pattern for BAT1704WE6327HTSA1?

Infineon recommends the standard SOT323-3 footprint per JEDEC MO-203AA: 0.9 mm pad length, 0.4 mm pad width, 0.65 mm pitch, with 0.25 mm solder mask opening. Thermal relief is advised for Pin 2 and Pin 3 cathodes to ensure reliable reflow joint formation without tombstoning.
