1.5KE110CA-B Equivalent & Substitute Parts

Part Overview

The 1.5KE110CA-B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Diodes Incorporated, rated for 1500W peak pulse power with a 152V maximum clamping voltage. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -55°C to 175°C and is housed in a DO-201 through-hole package suitable for general-purpose transient protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1.5KE110CA-B is determined by the following critical parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Current - Peak Pulse (10/1000µs): 9.9A nominal tolerance
• Power - Peak Pulse: 1500W
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C

Substitute parts must maintain electrical equivalence across all voltage and current ratings. Package variations (DO-201AA, DO-27, DO-201AE, DO-13) are acceptable provided the through-hole mounting type is preserved and pin configuration remains compatible. Active product status is preferred for long-term availability, though automotive-grade variants with AEC-Q101 qualification provide enhanced reliability for demanding applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the 1.5KE110CA-B across voltage, current, and power ratings. Selection should prioritize active product status for supply chain continuity.

Primary Substitutes (Active Status, Standard Grade):

• 1.5KE110CA-E3/54 (Vishay TransZorb® series) — Active status with 946 units in stock
• 1.5KE110CA-TP (Micro Commercial Co) — Active status with 1004 units in stock
• 1.5KE110CA (Taiwan Semiconductor Corporation) — Active status with 989 units in stock
• 1.5KE110CA-B (Littelfuse Inc.) — Active status with 980 units in stock

Automotive-Grade Substitute (AEC-Q101 Qualified):

• 1.5KE110CAHE3_A/C (Vishay TransZorb® series) — Active status, AEC-Q101 qualified, 654 units in stock. Suitable for automotive and high-reliability applications requiring formal qualification documentation.

Alternative Package Option:

• 1N6064A (Solid State Inc.) — Active status with 38,700 units in stock. Uses DO-13 package instead of DO-201. Electrical parameters are equivalent; package selection depends on PCB layout constraints and mechanical fit requirements.

All substitutes comply with ROHS3 and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use 1N6064A as a direct replacement for 1.5KE110CA-B?

A: Electrical parameters are equivalent. The primary difference is package type: 1N6064A uses DO-13 while 1.5KE110CA-B uses DO-201. Substitution is valid only if your PCB layout accommodates the DO-13 package footprint and axial lead spacing.

Q: What is the difference between standard and automotive-grade variants?

A: The 1.5KE110CAHE3_A/C carries AEC-Q101 qualification, indicating compliance with automotive reliability standards. Use this variant for automotive applications or systems requiring formal qualification documentation. Standard-grade parts are suitable for general-purpose industrial and consumer applications.

Q: Are there inventory considerations for selecting a substitute?

A: All active substitutes maintain adequate stock levels (654–38,700 units). The 1N6064A offers the highest inventory (38,700 units), while automotive-grade 1.5KE110CAHE3_A/C has lower availability (654 units). Procurement timelines should account for these differences.

Q: Do all substitutes meet the same compliance standards?

A: All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) ratings. REACH status varies: Vishay and Littelfuse parts are REACH Unaffected; Taiwan Semiconductor and Micro Commercial Co parts are REACH Unaffected; Solid State Inc. status is Vendor Undefined. Verify REACH compliance requirements for your specific application and region.

Q: Can I mix different manufacturers in the same design?

A: Yes. All substitutes maintain identical electrical specifications (94V standoff, 105V breakdown, 152V clamping, 1500W peak power). Mixing manufacturers is acceptable from an electrical standpoint; however, maintain consistent sourcing within production batches to ensure supply chain stability.

Q: What is the significance of the 10/1000µs pulse specification?

A: This defines the peak pulse current rating under a 10µs rise time and 1000µs pulse duration. All substitutes are rated for 9.9–10.3A under these conditions, confirming equivalent transient suppression capability. The slight variation (9.9A vs. 10.3A) is within acceptable tolerance for this component class.
