P4KE62C Equivalent & Substitute Parts

Part Overview

The P4KE62C is a bidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection in through-hole applications. This part operates with a 53V reverse standoff voltage and 400W peak pulse power rating in a DO-204AL (DO-41) axial package. The P4KE62C is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage clamping, peak pulse current, and thermal operating ranges while supporting the same through-hole mounting configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4KE62C is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): Must equal 53V
• Voltage - Clamping (Max) @ Ipp: Must not exceed 89.25V (lower values acceptable)
• Current - Peak Pulse (10/1000µs): Must support minimum 4.8A
• Power - Peak Pulse: Must equal or exceed 400W
• Operating Temperature Range: Must support -55°C ~ 175°C minimum
• Mounting Type: Must be Through Hole
• Package / Case: Must be DO-204AL or DO-41 (Axial)
• Type: Must be Zener bidirectional TVS diode

All identified substitute parts maintain the P4KE62 base product number designation and meet these electrical and mechanical compatibility criteria. Substitutes are available from multiple manufacturers including Taiwan Semiconductor Corporation, Vishay General Semiconductor, Micro Commercial Co, and Comchip Technology, with active product status enabling continued supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are electrically compatible with the P4KE62C across the critical voltage and current parameters. Selection should prioritize active product status to ensure long-term supply chain availability.

For applications requiring extended temperature operation to 175°C, select from: P4KE62CA (Taiwan Semiconductor Corporation), P4KE62CAHE3/54 (Vishay General Semiconductor with AEC-Q101 automotive qualification), P4KE62CA-AP, P4KE62CA-BP, or P4KE62CA-TP (all Micro Commercial Co).

For applications with maximum temperature requirements of 150°C, P4KE62CA-G (Comchip Technology) is suitable.

P4KE62CAHE3/54 includes AEC-Q101 automotive qualification, making it the preferred choice for automotive or mission-critical applications requiring formal qualification documentation.

All substitute parts maintain ROHS3 compliance where specified and support the same DO-204AL/DO-41 through-hole mounting configuration as the original P4KE62C.

Frequently Asked Questions (FAQ)

Q: Can P4KE62CA substitute for P4KE62C in all applications?

A: Yes. P4KE62CA meets all electrical compatibility criteria: 53V reverse standoff voltage, 85V clamping voltage (lower than the original 89.25V, providing improved protection margin), 5A peak pulse current (exceeds the 4.8A requirement), 400W power rating, and -55°C to 175°C operating temperature range. Both use identical DO-204AL/DO-41 through-hole packages.

Q: What is the difference between P4KE62CA-E3/54 and P4KE62CAHE3/54?

A: Both are manufactured by Vishay General Semiconductor with identical electrical specifications. P4KE62CAHE3/54 includes AEC-Q101 automotive qualification, making it suitable for automotive applications requiring formal qualification documentation. P4KE62CA-E3/54 is suitable for general-purpose applications.

Q: Why does P4KE62CA-G have a lower maximum operating temperature (150°C vs 175°C)?

A: P4KE62CA-G is manufactured by Comchip Technology with a specified maximum junction temperature of 150°C. For applications requiring operation to 175°C, select alternative substitutes with higher temperature ratings.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts use DO-204AL or DO-41 axial through-hole packages, maintaining mechanical compatibility with the original P4KE62C. Packaging format (Tape & Reel or Bulk) varies by manufacturer and supplier, but the component package remains identical.

Q: Which substitute offers the best supply chain continuity?

A: All listed substitutes have active product status. P4KE62CA (Taiwan Semiconductor Corporation) and P4KE62CA-E3/54 (Vishay General Semiconductor) represent established manufacturers with broad distribution networks. Micro Commercial Co variants (P4KE62CA-AP, P4KE62CA-BP, P4KE62CA-TP) and Comchip Technology P4KE62CA-G also maintain active production.
