P4KE62 Equivalent & Substitute Parts

Part Overview

The P4KE62 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This component features a 53V reverse standoff voltage, 89.25V maximum clamping voltage, and 400W peak pulse power rating in a through-hole DO-204AL (DO-41) axial package. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4KE62 are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 53V (exact match required)
• Voltage - Clamping (Max) @ Ipp: 85V to 89.25V (acceptable range for protection circuit compatibility)
• Current - Peak Pulse (10/1000µs): 4.7A to 5A (within functional tolerance)
• Power - Peak Pulse: 400W (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: DO-204AL, DO-41, Axial (exact match required)
• Operating Temperature Range: -55°C ~ 175°C (preferred) or -55°C ~ 150°C (acceptable)
• Unidirectional Channels: 1 (exact match required)

All substitute parts maintain the same base product number (P4KE62) designation and are functionally equivalent within these electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production components with electrical and mechanical compatibility to the obsolete P4KE62. Selection among substitutes should be based on the following criteria:

For general-purpose applications: P4KE62A (Taiwan Semiconductor Corporation) or P4KE62A-TP, P4KE62A-AP, P4KE62A-BP (Micro Commercial Co) are suitable. These parts maintain full compliance with ROHS3 standards and offer consistent availability.

For automotive-grade applications: P4KE62AHE3/54 (Vishay General Semiconductor - Diodes Division) is qualified to AEC-Q101 automotive standards and carries the TransZorb® series designation, providing enhanced reliability for automotive overvoltage protection circuits.

For applications requiring extended temperature operation: Parts rated to -55°C ~ 175°C (P4KE62A, P4KE62A-E3/54, P4KE62AHE3/54, P4KE62A-AP, P4KE62A-BP, P4KE62A-TP) are preferred over P4KE62A-G (Comchip), which is limited to -55°C ~ 150°C.

For packaging considerations: Tape & Reel packaging is available from Taiwan Semiconductor Corporation (P4KE62A) and Vishay (P4KE62AHE3/54). Bulk and Cut Tape options are available from other manufacturers.

Frequently Asked Questions (FAQ)

Q: Can I directly replace P4KE62 with any of the listed substitutes?

A: Yes. All listed parts maintain identical reverse standoff voltage (53V), peak pulse power (400W), mounting type (through-hole), and package format (DO-204AL/DO-41 axial). The clamping voltage differential (85V vs. 89.25V) and peak pulse current variations (4.7A to 5A) fall within acceptable functional tolerance for general-purpose transient suppression circuits.

Q: What is the difference between the Vishay P4KE62A-E3/54 and P4KE62AHE3/54?

A: Both parts are electrically identical with 53V standoff voltage, 85V clamping voltage, and 400W power rating. The primary difference is packaging: P4KE62A-E3/54 is supplied in Cut Tape (CT), while P4KE62AHE3/54 is supplied in Tape & Reel (TR). Additionally, P4KE62AHE3/54 carries AEC-Q101 automotive qualification, making it suitable for automotive applications.

Q: Why does the original P4KE62 have a higher clamping voltage (89.25V) than the substitutes (85V)?

A: The substitute parts maintain the same reverse standoff voltage (53V) and power rating (400W), which are the primary design parameters for circuit protection. The lower clamping voltage in substitutes provides improved protection margin. Both values are within acceptable operating ranges for the P4KE series TVS diodes.

Q: Are all substitutes ROHS3 compliant?

A: ROHS3 compliance is confirmed for P4KE62A (Taiwan Semiconductor), P4KE62A-E3/54 (Vishay), P4KE62AHE3/54 (Vishay), P4KE62A-G (Comchip), and the original P4KE62 (Littelfuse). ROHS status is not specified in the data for Micro Commercial Co variants (P4KE62A-AP, P4KE62A-BP, P4KE62A-TP).

Q: Which substitute offers the best availability?

A: Current inventory levels are provided for all parts. P4KE62AHE3/54 (Vishay) and P4KE62A-BP (Micro Commercial) each have 1000+ units in stock, offering strong availability for immediate procurement.

Q: Can I use P4KE62A-G in high-temperature applications?

A: P4KE62A-G is rated to -55°C ~ 150°C, which is 25°C lower than other substitutes rated to -55°C ~ 175°C. For applications requiring full -55°C ~ 175°C operation, select alternative substitutes from Taiwan Semiconductor, Vishay, or Micro Commercial Co.
