Infineon ESD231-B1-W0201 Series ESD Protection Diode, 5.5V Maximum Reverse Stand-Off Voltage, Bi‑Directional Diode Type - ESD231B1W0201E6327XTSA1


This ESD protection diode provides transient suppression for PCB-mounted circuits subject to electrostatic discharges and surge events. It operates across a wide temperature span and is intended to clamp high-voltage transients while allowing normal bidirectional signal operation. The component is supplied in a Compact WLL-2-1 package for surface mounting and is suitable for designs requiring low leakage and repeatable pulse-handling behaviour.

Features and Benefits:


• 132W Peak Pulse power protects against high-energy transients
• 12A Peak Pulse current absorbs short-duration surges
• 12V clamping voltage limits voltage exposure during ESD
• 1nA maximum reverse leakage minimises standby current draw
• -55°C to 125°C rated temperature range supports harsh environments

Applications


• Suitable for protecting signal lines on densely populated PCBs
• Ideal for safeguarding interfaces exposed to human contact
• Used with bidirectional data buses requiring clamping of both polarities
• Can be used for surge protection at input/output connectors
• Useful in designs requiring Compact WLL-2-1 package mounting

What is the diode configuration and how does it affect installation?


It is a single bidirectional diode allowing symmetric clamping without polarity-specific placement.

Which standards does it meet for immunity testing?


It complies with IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 for ESD and transient immunity.

What are the limits for reverse voltage and leakage during standby?


The maximum reverse stand-off voltage is 5.5V and the maximum reverse leakage is 1nA.

How does Pulse testing relate to real-world events?


It is characterised with a 10mA test current and specified for 12A Peak Pulse current handling during transient events.

What mounting and package considerations should be noted for PCB design?


It is supplied in a WLL-2-1 package intended for PCB mount and requires footprint matching for reliable solder attachment.
