3 Description

The TSD05C is a bidirectional TVS protection diode

designed for clamping harmful transients such as

ESD and surge. The TSD05C is rated to dissipate

ESD strikes up to ±30 kV (contact and air gap

discharge) and also meets the maximum level

specified in the IEC 61000-4-2 international standard

(Level 4). For surges, the device can clamp 8/20

μs surges with peak pulse currents up to 30 A in

accordance with the IEC 61000-4-5 standard.

This device also features a 4 pF (typical) IO

capacitance enabling it to protect high-speed data

lines. The low dynamic resistance and low clamping

voltage provides system level protection against

transient events.

Combining the robust clamping performance and low

capacitance of this device, TSD05C is an excellent

TVS diode to protect both data lines and power lines

in many different applications.

The TSD05C is offered in the industry standard,

leaded SOD-323 package to enable easy

solderability.
