Infineon Technologies ESD103B102ELSE6327XTSA1

Overview

ESD103B102ELSE6327XTSA1 from Infineon Technologies is a bi-directional ESD and transient protection diode designed for one-line interface protection in compact PCB layouts. The device belongs to the ESD103-B1-02ELS family and is selected where working voltage, capacitance, clamping behavior, and package footprint must match the protected signal path.

As an configuration of the ESD103-B1-02ELS family, ESD103B102ELSE6327XTSA1 combines ±15 V working voltage, 0.09 pF at 1 GHz typical line capacitance, IEC61000-4-2 ±14 kV air / ±10 kV contact ESD robustness, and a PG-TSSLP-2-4 / 0201-class package package. For engineers reviewing the ESD103B102ELSE6327XTSA1 datasheet, ESD103B102ELSE6327XTSA1 pinout, ESD103B102ELSE6327XTSA1 application, or ESD103B102ELSE6327XTSA1 equivalent, this device is commonly relevant to mobile antenna lines, LTE/WLAN RF interfaces, RF front-end protection, and low-capacitance exposed signal paths.

Technical Context

In a board-level protection design, ESD103B102ELSE6327XTSA1 should be placed close to the connector, antenna feed, user-accessible node, or exposed signal entry point. Short routing is important because trace inductance can increase the actual residual voltage seen by the protected IC during a fast ESD pulse.

The bi-directional structure and ±15 V working-voltage rating define the type of normal signal that can be protected without clipping. Its 0.09 pF at 1 GHz capacitance makes the device suitable for RF antenna and high-speed low-capacitance interfaces, while 48 V typical clamping at 16 A TLP and 1.8 Ω typical dynamic resistance define how strongly the diode limits transient stress.

ESD103B102ELSE6327XTSA1 should be evaluated with the final interface voltage, signal bandwidth, surge profile, connector exposure level, and PCB layout. part is listed with 15000-piece tape and reel, MSL 1 handling, lead-free and halogen-free compliance, and a not for new design lifecycle status.

Key Specifications

Pinout & Package

The ESD103B102ELSE6327XTSA1 pinout follows a two-terminal protection-device layout in the PG-TSSLP-2-4 / 0201-class package package. The protected line and reference return must be routed with minimum loop area, and orientation must be verified for uni-directional options.

For PCB design, place ESD103B102ELSE6327XTSA1 ahead of the sensitive IC and close to the transient entry point. Land pattern, stencil opening, solder mask, and inspection process should follow the manufacturer package drawing.

Key Features

• Bi-directional one-line ESD / transient protection diode.

Applications

Equivalent & Alternatives

When evaluating ESD103B102ELSE6327XTSA1 equivalent devices, engineers should compare working voltage, direction type, capacitance, ESD rating, EFT and surge capability, clamping voltage, dynamic resistance, package footprint, packing, and lifecycle status.

Compared with a generic TVS diode, ESD103B102ELSE6327XTSA1 should be selected by the protected line voltage, capacitance budget, residual clamping voltage, package land pattern, and system-level validation result rather than by package size alone.

Quality

ESD103B102ELSE6327XTSA1 should be sourced as original Infineon Technologies components through traceable and controlled supply channels. Quality verification may include reel-label inspection, package inspection, top-mark review, date-code review, solderability evaluation, and incoming sampling based on production risk.

Because small ESD diodes are often placed at external interfaces, correct storage, ESD-safe handling, MSL control, land-pattern accuracy, and traceability are important for stable assembly yield and reliable field protection. For products listed as not for new design, approved substitute planning should be completed before long-term production use.
