Infineon Technologies ESD101B102ELSE6327XTSA1

Overview

ESD101B102ELSE6327XTSA1 from Infineon Technologies is a low-capacitance ESD / transient protection diode designed for PCB-level ESD, EFT, surge, and transient protection in compact electronic systems. part is associated with the ESD101-B1-02ELS product family and uses the 0201 (0603 Metric) package with Tape & Reel (TR) packing for production assembly.

As an Infineon protection component, ESD101B102ELSE6327XTSA1 combines device-specific working voltage from Infineon datasheet working-voltage class, low or ultra-low capacitance value defined by the specific Infineon 02EL/02ELS series, 1 line, bi-directional, and compact package integration for connector-side or IC-side protection. For engineers reviewing the ESD101B102ELSE6327XTSA1 datasheet, ESD101B102ELSE6327XTSA1 pinout, ESD101B102ELSE6327XTSA1 application, or ESD101B102ELSE6327XTSA1 equivalent, this device is commonly evaluated for interface protection, portable electronics, communication ports, industrial modules, and exposed signal lines where transient current must be diverted before it reaches sensitive semiconductor pins.

Technical Context

In a practical PCB layout, ESD101B102ELSE6327XTSA1 should be placed close to the connector, exposed pad, cable entry point, or protected IC pin so the transient current is shunted before it travels through long board traces. The package and pin configuration determine whether the device is used as a single-line, multi-line, uni-directional, or bi-directional protection element.

The ESD101-B1-02ELS family parameters are relevant to signal integrity and protection margin. The working-voltage rating must stay above the normal operating level, while the line capacitance must remain compatible with the protected interface. Clamping voltage, dynamic resistance, surge current, and ESD rating determine how much residual stress reaches the downstream IC during IEC-style tests.

For the ESD101B102ELSE6327XTSA1 configuration, designers should verify the exact package drawing, orientation, reel or bulk packing, moisture sensitivity, lifecycle status, and any PCN or replacement guidance before production release. For high-speed or RF interfaces, the placement, ground return, and via structure can be as important as the diode rating itself.

Key Specifications

Pinout & Package

The ESD101B102ELSE6327XTSA1 pinout and package layout should be checked against the Infineon package drawing for the ESD101-B1-02ELS product family. The 0201 (0603 Metric) package is intended for compact PCB placement and should be oriented correctly before footprint, stencil, and inspection rules are finalized.

For ESD and TVS parts, the most effective layout normally uses short traces, a direct return path, and placement close to the transient entry point. For fuse-type BGF devices, the routing should place the fuse in series with the intended protected current path.

Key Features

• Low-capacitance esd / transient protection diode for ESD and transient protection use.
• 1 line, bi-directional supporting the intended protected-line arrangement.
• Working-voltage class: device-specific working voltage from Infineon datasheet.
• Line-capacitance class: low or ultra-low capacitance value defined by the specific Infineon 02EL/02ELS series.
• ESD robustness: IEC61000-4-2 system-level ESD rating from the device datasheet.
• EFT capability: EFT pulse rating from the device datasheet.
• Surge or peak-pulse capability: surge or peak-pulse rating from the device datasheet.
• Clamping behavior: clamping voltage defined by the device family and test waveform.
• 0201 (0603 Metric) package supports placement close to connectors and protected IC pins.
• RoHS and lead-free status should be verified from datasheet before production release.

Applications

Equivalent & Alternatives

When evaluating ESD101B102ELSE6327XTSA1 equivalent devices, engineers should compare package footprint, line count, directionality, working voltage, line capacitance, clamping behavior, leakage current, ESD rating, surge rating, lifecycle status, and assembly format.

Compared with another device in the same Infineon protection portfolio, ESD101B102ELSE6327XTSA1 should be selected only when its ESD101-B1-02ELS family parameters match the protected interface and PCB footprint. Substitution should not be based only on package size or voltage name because capacitance, clamping voltage, polarity, and transient-current rating can change system-level behavior.

Quality

ESD101B102ELSE6327XTSA1 should be sourced as original Infineon Technologies components through traceable and controlled supply channels. Quality verification may include package inspection, top-mark validation, date-code review, reel-label verification, solderability evaluation, and electrical sampling according to the needs of the production program.

For ESD, TVS, and fuse protection devices, layout validation and system-level stress testing are important. Engineers should confirm moisture handling, RoHS and halogen-free status, MSL level, lifecycle status, and product-change documentation before release for manufacturing.
