ICTE12CHE3_A/D Equivalent & Substitute Parts

Part Overview

The ICTE12CHE3_A/D is a 1.5KE series TransZorb® bidirectional TVS diode manufactured by Vishay General Semiconductor - Diodes Division. This component is rated for 12V reverse standoff voltage with a 17.1V maximum clamping voltage and 70A peak pulse current. The part is classified as obsolete, necessitating identification of equivalent and substitute components that maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ICTE12CHE3_A/D is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 12V nominal
• Voltage - Clamping (Max) @ Ipp: Maximum 17.1V
• Current - Peak Pulse (10/1000µs): Minimum 70A
• Power - Peak Pulse: 1500W (1.5kW)
• Mounting Type: Through Hole
• Package / Case: DO-201AA, DO-27, or Axial
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Bidirectional Channels: 1

Substitute parts are grouped based on electrical equivalence within these parameters. Parts with identical or superior electrical ratings and compatible packaging are considered direct substitutes. Parts with reduced peak pulse current or power dissipation are listed as functional alternatives with application-dependent suitability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Electrical Equivalence):

The 1.5KE15CAHE3_A/D from Vishay and 1.5KE15CA from Taiwan Semiconductor Corporation are the preferred substitutes. Both maintain the 1500W peak pulse power rating, support 70A+ peak pulse current, and are available in compatible through-hole axial packages. Both parts are AEC-Q101 qualified or equivalent automotive-grade components and are currently in active production status.

Secondary Substitutes (Active Status, Reduced Power Dissipation):

The P6KE15CA from Fairchild Semiconductor is rated for 600W peak pulse power and 29A peak pulse current. This part is suitable for applications where peak pulse current requirements do not exceed 29A. The operating temperature range is -50°C ~ 175°C, which is narrower than the original specification.

Not Recommended:

The 1N6148 from Semtech Corporation is discontinued at DiGi Electronics and does not provide sufficient peak pulse current (57A) relative to the original 70A specification. The SA12CA is obsolete and provides only 500W peak pulse power and 25.1A peak pulse current, making it unsuitable for applications requiring the full 1500W rating.

The P6KE16CA lacks complete electrical parameter specifications and cannot be reliably evaluated for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE15CAHE3_A/D directly replace the ICTE12CHE3_A/D?

A: Yes. The 1.5KE15CAHE3_A/D maintains the same 1500W peak pulse power rating, exceeds the 70A peak pulse current requirement with 70.8A, and is available in the same DO-201AA, DO-27, and axial packages. The slightly higher clamping voltage (21.2V vs. 17.1V) and reverse standoff voltage (12.8V vs. 12V) are within acceptable tolerance for TVS diode substitution.

Q: What is the difference between the 1.5KE15CAHE3_A/D and 1.5KE15CA?

A: Both parts share identical electrical specifications (12.8V reverse standoff, 21.2V clamping voltage, 1500W peak pulse power). The primary difference is manufacturer: Vishay versus Taiwan Semiconductor Corporation. Both are active production parts with equivalent performance.

Q: Why is the P6KE15CA listed as a substitute if it has lower power rating?

A: The P6KE15CA is listed as a functional alternative for applications where peak pulse current does not exceed 29A. The 600W power rating is insufficient for the original 1500W specification. Selection of this part requires verification that application requirements do not exceed its electrical limits.

Q: Are there package compatibility considerations?

A: The original ICTE12CHE3_A/D is available in DO-201AA, DO-27, and axial packages. The 1.5KE15CAHE3_A/D and 1.5KE15CA maintain these same package options. The P6KE15CA uses DO-204AC (DO-15) and axial packages, which are mechanically different. Verify PCB footprint compatibility before selection.

Q: What certifications apply to the substitute parts?

A: The 1.5KE15CAHE3_A/D is AEC-Q101 qualified, matching the original part's automotive qualification. The 1.5KE15CA from Taiwan Semiconductor Corporation is an active production part suitable for general purpose applications. The P6KE15CA is an active production part without specified automotive qualification.
