Infineon Technologies ESD201-B2-03LRHE6327

Overview

ESD201-B2-03LRHE6327 from Infineon Technologies is a two-line bi-directional protection device designed for ESD, EFT, surge, and transient suppression in exposed electronic interfaces. The device belongs to the ESD201-B2-03LRH protection family and is selected where working voltage, capacitance, clamping behavior, package footprint, and protected-line count must match the target circuit.

As an configuration of the ESD201-B2-03LRH family, ESD201-B2-03LRHE6327 combines ±5.5 V working-voltage class, low capacitance for compact line protection, IEC61000-4-2 system-level ESD protection class, and a SC-101, SOT-883 package. For engineers reviewing the ESD201-B2-03LRHE6327 datasheet, ESD201-B2-03LRHE6327 pinout, ESD201-B2-03LRHE6327 application, or ESD201-B2-03LRHE6327 equivalent, this device is commonly relevant to mobile and embedded connector protection, connector-side protection, compact embedded boards, and system-level immunity design.

Technical Context

In a board-level protection design, ESD201-B2-03LRHE6327 should be placed close to the connector, exposed signal entry point, RF feed, control line, or supply node that may receive an ESD or surge event. Short routing is important because trace inductance can raise the residual voltage seen by the protected IC during fast IEC discharge pulses.

The bi-directional structure, ±5.5 V working-voltage class, and low capacitance for compact line protection determine where the device can be used without excessive signal loading or unwanted clipping during normal operation.

Key Specifications

Pinout & Package

The ESD201-B2-03LRHE6327 pinout should be reviewed as a protection-device connection rather than a functional logic pinout. The relevant connections are the protected line terminal, reference or ground terminal where present, and any additional line terminals used by multi-line array versions.

For PCB design, ESD201-B2-03LRHE6327 should be placed ahead of the sensitive IC and close to the transient entry point. Land pattern, package orientation, solder mask, stencil opening, and inspection process should follow the manufacturer package drawing for the SC-101, SOT-883 package.

Key Features

• Two-line bi-directional protection for ESD and transient protection use.
• Working-voltage class: ±5.5 V.
• Line-capacitance class: low capacitance for compact line protection.
• ESD robustness: IEC61000-4-2 system-level ESD protection class.
• EFT capability: EFT immunity should be verified against the exact device family rating.
• Surge or peak-pulse capability: surge or peak-pulse capability should be checked against the exact pulse waveform requirement.
• SC-101, SOT-883 package supports close placement at exposed interfaces.
• Bulk supports SMT manufacturing flow.
• RoHS, lead-free, halogen-free, MSL, and lifecycle status should be verified from the exact documentation.

Applications

Equivalent & Alternatives

When evaluating ESD201-B2-03LRHE6327 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, ESD201-B2-03LRHE6327 should be selected by protected-line voltage, capacitance budget, residual clamping voltage, package land pattern, and system-level validation result rather than by package size alone.

Quality

ESD201-B2-03LRHE6327 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 and TVS devices 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.
