Frequently Asked Questions (FAQ)

Q: Can P4KE13A replace MP4KE13AE3 in all applications?

A: P4KE13A provides electrical and mechanical equivalence across all critical parameters. However, applications requiring military-grade qualification per MIL-PRF-19500 must retain MP4KE13AE3. Applications subject to RoHS regulations require P4KE13A due to its ROHS3 compliance status.

Q: What is the difference in peak pulse current between these parts?

A: MP4KE13AE3 is rated for 22A peak pulse current, while P4KE13A is rated for 23A. Both parts maintain the same 400W peak pulse power rating and identical clamping voltage of 18.2V. The higher current rating of P4KE13A provides additional margin in transient suppression applications.

Q: Are the operating temperature ranges compatible?

A: MP4KE13AE3 operates from -65°C to 150°C (TJ), while P4KE13A operates from -55°C to 175°C (TJ). P4KE13A provides an extended upper temperature limit. Applications requiring operation below -55°C must use MP4KE13AE3.

Q: What packaging differences exist between these parts?

A: MP4KE13AE3 is supplied in Bulk packaging, while P4KE13A is supplied in Tape & Reel (TR) format. Both use identical DO-204AL (DO-41) axial through-hole package geometry. Packaging selection depends on manufacturing process requirements: bulk for manual assembly or small-volume production, tape & reel for automated assembly lines.

Q: Are the voltage specifications identical?

A: Yes. Both parts share identical voltage specifications: 11.1V reverse standoff voltage, 12.4V minimum breakdown voltage, and 18.2V maximum clamping voltage. These parameters are determined by the shared base product number P4KE13.

Q: What compliance certifications apply to each part?

A: MP4KE13AE3 holds military-grade qualification (MIL-PRF-19500) and is RoHS non-compliant. P4KE13A is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 ECCN classification and identical HTSUS code 8541.10.0080.
