P4KE12A-G Equivalent & Substitute Parts

Part Overview

The P4KE12A-G is a unidirectional Transient Voltage Suppressor (TVS) diode designed for general-purpose overvoltage protection applications. Manufactured by Comchip Technology, this through-hole component operates across a wide temperature range and meets ROHS3 compliance requirements. The part is currently in active production status with 1018 units available in bulk packaging. Identifying equivalent and substitute parts becomes necessary when bulk packaging is unavailable, when alternative manufacturers offer improved lead times, or when design flexibility permits component standardization across production batches.

Substitute Part Grouping Explanation

Substitution of the P4KE12A-G is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 10.2V
• Voltage - Breakdown (Min): 11.4V
• Voltage - Clamping (Max) @ Ipp: 16.7V
• Current - Peak Pulse (10/1000µs): minimum 23.95A
• Power - Peak Pulse: 400W
• Mounting Type: Through Hole
• Package / Case: DO-204AL or DO-41 compatible
• Type: Zener, Unidirectional
• RoHS Status: ROHS3 Compliant

The P4KE12A manufactured by Taiwan Semiconductor Corporation meets all substitution criteria. Both parts share identical voltage specifications, equivalent current handling capability, and compatible through-hole packaging. The substitute part operates across an extended temperature range (-55 to 175°C) and is available in tape & reel packaging, providing operational flexibility while maintaining electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The P4KE12A manufactured by Taiwan Semiconductor Corporation is a direct electrical equivalent to the P4KE12A-G. Both components maintain identical voltage specifications, equivalent current ratings, and compatible through-hole packaging. The substitute part meets all ROHS3 compliance and REACH unaffected requirements, ensuring regulatory equivalence.

Selection between these parts should be based on packaging requirements and availability. The Comchip P4KE12A-G is supplied in bulk packaging, while the Taiwan Semiconductor P4KE12A is available in tape & reel format. The Taiwan Semiconductor variant provides an extended operating temperature range to 175°C, which may offer additional design margin in temperature-sensitive applications. Both parts carry active product status and are in current production.

Frequently Asked Questions (FAQ)

Q: Can the P4KE12A (Taiwan Semiconductor) be used as a direct replacement for the P4KE12A-G (Comchip)?

A: Yes. Both parts are electrically equivalent across all critical parameters: reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and power dissipation. Both are through-hole mounted in DO-41/DO-204AL packages and meet ROHS3 compliance.

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

A: The P4KE12A-G is rated at 23.95A, while the P4KE12A is rated at 25A. The substitute part exceeds the original specification, providing additional current handling margin without compromising circuit protection.

Q: Are there packaging differences between these parts?

A: Yes. The P4KE12A-G is supplied in bulk packaging, while the P4KE12A is supplied in tape & reel (TR) format. Both are through-hole components with identical mechanical compatibility.

Q: Does the extended temperature range of the P4KE12A affect substitution suitability?

A: No. The P4KE12A operates from -55 to 175°C, compared to -55 to 150°C for the P4KE12A-G. The extended range represents an operational advantage and does not compromise compatibility in applications within the original temperature specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the P4KE12A-G and P4KE12A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
