Infineon ESD128-B1-W0201 Series ESD Protection Diode, 18V Reverse Stand-Off Voltage, 32V Clamping Voltage - ESD128B1W0201E6327XTSA1


This ESD protection diode provides transient suppression for sensitive circuitry in surface-mount assemblies. It operates over a wide temperature range suitable for demanding environments and offers bi-directional protection against electrostatic and surge events. The device is designed for PCB mounting in a Compact SMT package and supports Pulse handling appropriate for short-duration transients.

Features and Benefits:


• 2A Peak Pulse current reduces transient stress on signal lines
• 32V clamping voltage limits voltage excursions during surges
• 1nA maximum reverse leakage conserves standby current
• 45W Peak Pulse power absorbs high-energy spikes
• Bi-directional configuration protects lines in both polarities

Applications


• Suitable for protecting data and signal interfaces on PCBs
• Ideal for boards exposed to IEC 61000-4-2 ±15kV ESD events
• Used with equipment requiring surface-mount transient suppression
• Can be used for surge-prone input protection on modules
• Suitable for Compact assemblies needing low-leakage protection

What temperature range can it withstand during operation?


It functions across an operating span from -55°C to 125°C.

How is surge immunity characterised for short pulses?


It meets ±2A (8/20 μs) surge capability and 45W Peak Pulse power dissipation for Pulse handling.

What package and mounting type are used for board assembly?


It is supplied in a WLL-2-1 SMT package intended for PCB mounting.

How does the device behave with fast transients and EFT?


It conforms to ±2kV/±40A (5/50 ns) EFT specifications for fast transient suppression.
