1.5KE22A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 1.5KE22A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener diode operates through a DO-201AE axial package and delivers 1500W peak pulse power with a 30.6V maximum clamping voltage. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, manufacturing discontinuation, or supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1.5KE22A-TP are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 18.8V
• Voltage - Breakdown (Min): 20.9V
• Voltage - Clamping (Max) @ Ipp: 30.6V
• Power - Peak Pulse: 1500W
• Operating Temperature Range: -55°C to 175°C
• Mounting Type: Through Hole
• Package / Case: DO-201 series (DO-201AA, DO-27, Axial compatible)
• Type: Zener, Unidirectional
• RoHS Status: ROHS3 Compliant

All identified substitutes meet these parameters within the allowed tolerances for TVS diode applications. Packaging variations (Cut Tape, Tape & Reel, Bulk) do not affect electrical equivalency but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and ROHS3 compliance, ensuring regulatory alignment with current environmental standards. The 1.5KE22A from Taiwan Semiconductor Corporation offers the highest peak pulse current specification at 51A, providing additional margin in high-transient applications. The 1.5KE22A-B from Littelfuse Inc. and 1N6279A-E3/54 from Vishay General Semiconductor deliver comparable performance with peak pulse currents of 49.7A and 49A respectively, both within acceptable operating parameters for the 1.5KE22A-TP application envelope.

Packaging format selection should align with assembly requirements: Cut Tape (CT) for manual or semi-automated placement, Tape & Reel (TR) for high-volume automated assembly, and Bulk for inventory consolidation. All substitute parts are mechanically compatible with DO-201 series footprints and through-hole assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 1.5KE22A from Taiwan Semiconductor Corporation directly replace 1.5KE22A-TP?

A: Yes. Both parts share identical voltage specifications (18.8V reverse standoff, 20.9V breakdown minimum, 30.6V clamping maximum), 1500W peak pulse power rating, and -55°C to 175°C operating temperature range. The TSC variant is packaged in Tape & Reel format versus Cut Tape, but electrical performance is equivalent.

Q: What is the difference between DO-201AE and DO-201AA packages?

A: Both are axial through-hole packages for TVS diodes. DO-201AE and DO-201AA are mechanically compatible variants within the DO-201 family. All substitute parts support DO-201AA, DO-27, and axial configurations, ensuring PCB footprint compatibility.

Q: Are there peak pulse current differences between substitutes?

A: Yes. The 1.5KE22A (TSC) specifies 51A peak pulse current, while 1.5KE22A-B (Littelfuse) and 1N6279A-E3/54 (Vishay) specify 49.7A and 49A respectively. These variations remain within acceptable tolerance for the 1500W power rating and do not affect substitution eligibility for general-purpose transient suppression applications.

Q: Do all substitutes meet RoHS and REACH compliance?

A: Yes. All listed substitutes are ROHS3 compliant and REACH unaffected, matching the regulatory status of the 1.5KE22A-TP.

Q: Which packaging format is recommended for automated assembly?

A: Tape & Reel (TR) format, such as the 1.5KE22A from Taiwan Semiconductor Corporation, is optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) and Bulk formats are suitable for lower-volume or manual assembly workflows.
