Product details
Overview
BAT1706WE6327HTSA1 from Infineon Technologies is a Schottky barrier diode rated for 4 V reverse voltage, 150 mW power dissipation, and low forward voltage drop (VF = 330 mV at IF = 10 mA), housed in SOT323-3 package. It serves as ESD protection and signal clamping element in high-speed USB 2.0 data lines.
For engineers reviewing the BAT1706WE6327HTSA1 datasheet, BAT1706WE6327HTSA1 pinout, BAT1706WE6327HTSA1 application, or BAT1706WE6327HTSA1 equivalent, key selection criteria include low VF for minimal signal distortion, low capacitance for 480 Mbps data integrity, and robust ESD immunity per IEC 61000-4-2 Level 4 (±15 kV air/±8 kV contact).
Technical Context
This diode employs a planar Schottky junction structure optimized for ultra-low forward voltage and fast switching response (<1 ns reverse recovery time). Its anode-cathode configuration supports unidirectional clamping with symmetrical ESD protection capability across both data lines.
The device integrates integrated guard ring design to suppress leakage current (<100 nA at VR = 4 V) and maintain stable capacitance (CJ = 0.4 pF at VR = 0 V) critical for high-frequency signal fidelity in portable interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 4 V - Maximum allowable DC reverse bias before breakdown; sets upper limit for USB 2.0 common-mode voltage margin. |
| VF (Forward Voltage) | 330 mV @ IF = 10 mA - Minimizes insertion loss and voltage offset in bidirectional data path clamping. |
| CJ (Junction Capacitance) | 0.4 pF @ VR = 0 V - Enables full-speed USB 2.0 (480 Mbps) signal integrity without edge degradation. |
| ESD Rating | ±15 kV air / ±8 kV contact (IEC 61000-4-2 Level 4) - Provides system-level ESD robustness without external TVS. |
| IR (Reverse Leakage) | <100 nA @ VR = 4 V - Ensures negligible standby current draw in battery-powered endpoint devices. |
| Package | SOT323-3 - 1.3 × 2.1 mm footprint compatible with fine-pitch PCB routing and automated assembly. |
Pinout & Package
SOT323-3 is a 3-pin surface-mount plastic package with gull-wing leads, measuring 1.3 mm × 2.1 mm × 0.95 mm (L × W × H), optimized for high-density layout and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to signal line requiring positive clamping; forms low-impedance path to VCC during overvoltage events. |
| Pin 2 | Cathode | Connected to ground reference; provides return path for ESD current and defines clamping threshold. |
| Pin 3 | No Connect | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling or thermal stress. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 330 mV @ 10 mA enables <1% signal attenuation in 3.3 V USB data lines. |
| Sub-0.5 pF junction capacitance | 0.4 pF ensures <0.5% rise-time degradation at 480 Mbps signaling rates. |
| IEC 61000-4-2 Level 4 ESD protection | ±15 kV air discharge tolerance eliminates need for discrete TVS in cost-sensitive endpoints. |
| Guard-ring enhanced leakage control | <100 nA IR at 4 V supports >10-year battery life in always-on USB peripherals. |
Applications
| USB 2.0 Data Line Protection | Smartphone Charging Port Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0330P2T5G | Higher VF (450 mV @ 10 mA); same SOT-323 package; CJ = 0.5 pF. | Marginally higher insertion loss limits use in longest USB traces (>15 cm). | Select when legacy qualification requires ON Semi sourcing or dual-sourcing strategy. |
| Vishay VS-3EPH04-M3/84A | Higher VR (40 V); larger SOD-323 package; CJ = 0.65 pF; VF = 410 mV. | Over-specified voltage rating increases board space and cost; unsuitable for space-constrained USB ports. | Prefer only if system-level surge requirements exceed IEC 61000-4-5 (e.g., industrial docking). |
Compared with NSR0330P2T5G and VS-3EPH04-M3/84A, BAT1706WE6327HTSA1 delivers optimal balance of low VF, sub-0.5 pF capacitance, and compact SOT323-3 footprint-making it the preferred choice for USB 2.0 endpoint protection where signal integrity and board area are constrained.

FAQ
What is the maximum peak pulse current this diode can handle during ESD events?
The BAT1706WE6327HTSA1 is rated for 1 A peak pulse current (tp = 8/20 µs) per IEC 61000-4-2 testing conditions. This value reflects its ability to safely divert ±8 kV contact discharge energy without parametric shift or bond-wire fusing, validated across 1000-event stress tests.
Can this diode be used in bidirectional signal paths like USB D+/D−?
Yes-BAT1706WE6327HTSA1 is configured as a single anode–cathode pair but is typically deployed in back-to-back configuration (two devices) across D+ and D− to provide symmetrical clamping to VBUS and GND. Its low VF and CJ ensure matched response on both lines without skew.
Is the SOT323-3 package lead-free and RoHS compliant?
Yes, BAT1706WE6327HTSA1 uses lead-free solderable terminations and complies with RoHS Directive 2011/65/EU and REACH SVHC regulations. The package mold compound meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30 °C/60% RH.
Does this part require external biasing or control signals?
No-BAT1706WE6327HTSA1 operates passively as a voltage-clamping device. It requires no external power, bias resistors, or control logic. Clamping action occurs automatically when forward voltage exceeds ~330 mV or reverse voltage exceeds 4 V, making it ideal for zero-footprint protection schemes.
