What are the key features of CPDT-12V?

Bidirectional transient voltage suppression with 12 V standoff and 25 W peak pulse power
Dual common-anode silicon elements in a compact SOT-23 3-pin package for space-constrained designs
Low clamping voltage max 25 V ensures robust protection of downstream circuitry
Fast response time suitable for ESD and EFT transient suppression on data lines

What is CPDT-12V used for?

The CPDT-12V is widely used for ESD protection on USB, HDMI, and RS-485 data lines, where bidirectional suppression is needed without exceeding the 12 V standoff threshold. Its compact SOT-23 footprint makes it ideal for portable electronics and wearables where board space is limited. Industrial and consumer applications benefit from its 25 W peak power rating to handle repetitive transient events reliably.

Frequently Asked Questions

What is the standoff voltage and peak pulse power rating of the CPDT-12V?

The CPDT-12V has a 12 V standoff voltage and supports up to 25 W non-repetitive peak reverse power dissipation, with a maximum clamping voltage of 25 V, making it suitable for protecting circuits operating at 12 V from transient overvoltages and ESD events.

Which interface protection scenarios does the CPDT-12V support given its bidirectional configuration?

With its bidirectional, dual common-anode silicon configuration, the CPDT-12V protects full-duplex data lines such as RS-485 and CAN bus operating at up to 12 V, as well as USB and HDMI signal lines where transients can occur in either polarity, all within a 3-pin SOT-23 package.

How does the CPDT-12V compare to a unidirectional TVS diode for the same 12 V standoff application?

Unlike a unidirectional TVS that blocks only reverse transients, the CPDT-12V handles bidirectional transients up to 25 W peak, with a breakdown voltage minimum of 13 V and nominal 17 V. This makes it preferable for AC-coupled or differential signal lines where transients can swing both above and below ground.

Can the CPDT-12V be used in industrial designs requiring compliance with JESD-609 and RoHS standards?

Yes, the CPDT-12V carries a JESD-609 code of e3, indicating RoHS-compliant lead-free terminations, making it suitable for industrial and consumer designs that must meet environmental directives, especially in applications running at 12 V supply rails with strict transient protection requirements.
