P4SMA170CA TR13 Equivalent & Substitute Parts

Part Overview

The P4SMA170CA TR13 is a transient voltage suppressor (TVS) diode manufactured by Central Semiconductor Corp, designed for general-purpose overvoltage protection in surface mount applications. This component features a 170V reverse standoff voltage with a 275V maximum clamping voltage and 1.4A peak pulse current capability in a compact SMA package.

The P4SMA170CA TR13 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system reliability when original inventory becomes depleted.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ170CA-13-F be used as a direct replacement for the P4SMA170CA TR13?

A: Yes. Both components share identical electrical specifications (170V standoff, 189V breakdown minimum, 275V clamping maximum, 1.4A peak pulse current, 400W peak power) and mechanical characteristics (DO-214AC SMA package, surface mount configuration, single bidirectional channel). Pin-to-pin and footprint compatibility is maintained.

Q: What is the primary difference between these two parts?

A: The P4SMA170CA TR13 is obsolete with limited remaining inventory. The SMAJ170CA-13-F is an active product with established supply availability and current manufacturing support.

Q: Are there packaging differences between these parts?

A: Both components use the DO-214AC SMA surface mount package. The SMAJ170CA-13-F is supplied in Tape & Reel format, which is standard for high-volume automated assembly. The original part was supplied in bulk form.

Q: Do regulatory certifications differ between these parts?

A: The SMAJ170CA-13-F carries RoHS3 compliance and REACH unaffected status. Regulatory documentation for the obsolete P4SMA170CA TR13 may not reflect current standards.

Q: Is the operating temperature range identical?

A: Yes. Both parts operate across the -55°C to 150°C junction temperature range, ensuring equivalent thermal performance in all specified operating conditions.
