Infineon Technologies ESD24VS2UE6327HTSA1

Overview

ESD24VS2UE6327HTSA1 from Infineon Technologies is a silicon TVS diode designed for ESD and transient protection in CAN/LIN bus networks, industrial control interfaces, 12 V / 24 V DC supply lines, and automotive-style transient environments. The device provides 24 V reverse working voltage, high ESD withstand capability, surge protection, low clamping voltage, and compact SOT23 surface-mount integration.

As part of the Infineon ESD24VS2U multi-purpose ESD protection family, ESD24VS2UE6327HTSA1 supports IEC61000-4-2 ESD protection up to ±30 kV, IEC61000-4-4 EFT protection up to 80 A, and IEC61000-4-5 surge current handling up to 5 A. For engineers reviewing the ESD24VS2UE6327HTSA1 datasheet, ESD24VS2UE6327HTSA1 pinout, ESD24VS2UE6327HTSA1 application, or ESD24VS2UE6327HTSA1 equivalent, this device is commonly used near connectors, field wiring, CAN/LIN transceivers, and exposed power-supply inputs where fast transient suppression is required.

Technical Context

In system-level protection design, ESD24VS2UE6327HTSA1 is normally placed close to the connector or transient entry point so that ESD and surge currents are diverted before they reach the protected IC, transceiver, or power-management circuit. Short routing, low loop inductance, and a direct ground connection are important because parasitic inductance can increase the actual voltage seen by the protected node during a fast ESD event.

The device can be used as a two-line uni-directional protection diode when pins 1 and 2 protect separate lines with pin 3 connected to ground. It can also be used as a one-line bi-directional protection structure between pins 1 and 2 when pin 3 is left unconnected, which is useful for single-wire CAN or LIN-style signal protection where the protected line may experience positive and negative transient stress.

ESD24VS2UE6327HTSA1 is optimized for applications that require higher working voltage than low-voltage data-line ESD protectors. Its 24 V working voltage, 26 V to 32 V breakdown range, 41 V maximum clamping voltage at 5 A surge current, and SOT23 package make it suitable for industrial and automotive-adjacent protection circuits where the protected line may normally operate above logic-signal voltage levels.

Key Specifications

Pinout & Package

The ESD24VS2UE6327HTSA1 pinout is based on a 3-pin SOT23 package. In the standard two-line uni-directional application, pins 1 and 2 connect to the protected lines and pin 3 is connected directly to the ground plane. For one-line bi-directional protection, the protected line can be connected between pins 1 and 2 while pin 3 remains not connected.

For PCB design, the TVS diode should be placed very close to the connector, bus entry point, or supply-line exposure point. The ground connection should be short and direct, and the protected line should pass through the protection location before reaching the sensitive IC or transceiver. This layout approach helps reduce trace inductance and improves transient clamping effectiveness.

Applications

Equivalent & Alternatives

When evaluating ESD24VS2UE6327HTSA1 equivalent devices, engineers should compare reverse working voltage, breakdown voltage, clamping voltage, surge current rating, ESD rating, capacitance, SOT23 pin configuration, uni-directional or bi-directional connection method, packing format, and lifecycle status.

Compared with low-voltage data-line ESD protectors, ESD24VS2UE6327HTSA1 is intended for higher-voltage interface and supply-line environments. ESD24VS2UE6327HTSA1 vs other 24 V SOT23 TVS diode selection should focus on clamping voltage, surge waveform rating, capacitance, leakage, pin connection method, and availability rather than only package size.

Quality

ESD24VS2UE6327HTSA1 should be sourced as original Infineon Technologies components through traceable and controlled supply channels. Quality verification procedures may include package inspection, top-mark validation, date-code review, reel-label verification, solderability evaluation, electrical sampling, and incoming inspection according to industrial or interface-protection production requirements.

Because Infineon lists this product as discontinued, procurement should pay special attention to lifecycle status, last-time-buy planning, storage condition, MSL 1 handling, RoHS and lead-free documentation, and replacement-product qualification. For repair or long-term maintenance programs, confirming the SOT23 footprint, TVS polarity, clamping performance, and system-level transient test requirements helps reduce sourcing and reliability risk.
