TVS (Transient Voltage Suppression) diodes are electrical components used for protecting sensitive electronic parts from events causing voltage spikes like lightning strikes. SMP26-E3/85A is a bi-directional, parallel-connection TVS Diode manufactured by NXP. It is available in a small-size package and is suitable for providing reliable protection against ESD.

SMP26-E3/85A is a TVS Diode suitable for high-speed, low capacitance ESD protection of OE, OC, CD, and PD lines. It is able to provide protection from electrostatic transient overvoltage at levels greater than 4 kV (contact discharge). The device is backwards compatible with IEC 61000-4-2, Level 4 as well as other industry specifications.

The working principle of SMP26-E3/85A is to protect the device from overvoltage pulses due to lightning strikes or from ESD (Electrostatic Discharge) events. When a voltage higher than the on-state voltage of the SMP26-E3/85A passes through it, the diode enters into conductive state and limits the voltage to a safe level. This will protect the connected electronic device from overvoltage voltage spikes.

SMP26-E3/85A has the following applications:

• It can be used in the telecom and industrial environments to protect against ESD, surges, and lightning.
• It is suitable for use in server systems, main power supplies, instruments, and desktop PCs.
• It can also be used to protect automotive electronics and communications systems.

The SMP26-E3/85A is designed to provide reliable surge protection and is able to protect against overvoltage transients of up to 8 kV (contact discharge) and up to 4 kV (air discharge). The device is a bi-directional TVS Diode and requires only 1 external electronic component such as a resistor. It is available in a RoHS compliant package and has an operating temperature range of -55°C to 125°C.

SMP26-E3/85A is a reliable small-size TVS Diode designed to protect against ESD pulses up to 8 kV contact discharge and can work over a wide temperature range. It is suitable for several applications like telecom and industrial environments, server systems, main power supplies, instruments, desktop PCs, and automotive electronics.
