A focus on speed

TI's diode process was built with speed in mind, meaning you will find industry-leading capacitance at every voltage.

New releases of ESD protection diodes

Protection for CAN and LIN

Final assembly of an automobile can be rife with opportunities for ESD as cables accumulate excess charge throughout the factory. ESD can also occur during maintinence any time cables are manipulated. Protect your systems from up to 30kV strikes with our selection of 24V solutions.

Featured products for CAN & LIN
ESD2CAN24-Q1 ACTIVE Automotive, dual, 3-pF, ±24-V, ±30-kV ESD protection diode for in-vehicle networks
ESD2CANFD24-Q1 ACTIVE Automotive, dual, 2.5pF ±24-V, 25-kV ESD protection diode for in-vehicle networks
ESD1LIN24-Q1 ACTIVE Automotive, 2.3-pF, ±24-V, ±30-kV ESD protection diode for LIN interfaces in SOD-32

The 'do-It-all' diodes

There are countless 24V lines across many systems, protect them all with a selection of diodes with multiple ratings and packages.

Featured products for general-purpose 24V protection
ESD752 ACTIVE Dual, 3-pF, ±24-V, ±30-kV ESD protection diode with 8/20-µS surge
ESD751 ACTIVE 1.6-pF ±24-V ±22-kV ESD protection diode for USB power delivery
ESD762 ACTIVE Dual 1.7-pF ±24-V ±20-kV ESD protection diode with 8/20-µS surge

Big protection, small package

Some of our smallest electronics carry the largest risk of ESD damage. Think about the smartwatch and phone you tap on and charge every day, the individual keys on your laptop's keyboard, ESD protection cannot be compromised due to lack of space. Therefore, we have released 30kV, low capacitance diodes in DFN0603.

Featured products for 30kV protection in DFN0603
ESD441 ACTIVE 1-pF, 5.5-V, 30-KV ESD protection device in 0201 package
ESD451 ACTIVE 0.5-pF, 5.5-V, 30-KV bidirectional ESD protection device in 0201 package
ESD341 ACTIVE 0.66-pF ±3.6-V ±30-kV ESD protection diode with 5.4-A surge rating in 0201 package
