30KP160CA-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 30KP160CA-TP is a Zener-type Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in through-hole applications. This bidirectional TVS diode operates with a reverse standoff voltage of 160V and provides peak pulse power dissipation of 30kW, making it suitable for high-energy transient suppression. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Equivalent and substitute parts are identified based on matching electrical characteristics including reverse standoff voltage, breakdown voltage, clamping voltage, and thermal operating range, while accommodating variations in peak pulse power ratings and package configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KP160CA-TP are qualified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Reverse Standoff Voltage: 160V (exact match required)
• Breakdown Voltage (Min): 178V–178.7V range
• Bidirectional Channels: 1 (single channel)
• Type: Zener TVS diode
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Applications: General Purpose
• RoHS3 Compliance: Required

Secondary Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: 252.6V–259V acceptable range
• Power - Peak Pulse: 5kW–30kW (power rating may vary based on application requirements)
• Package / Case: R-6 or P600 axial packages acceptable
• Current - Peak Pulse (10/1000µs): Varies with power rating

The identified substitute parts maintain electrical compatibility within the specified voltage and thermal parameters while accommodating different power dissipation ratings and package configurations suitable for equivalent circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—30KP160CA-TP, 20KPA160CA, and 5KP160CA—are Active products with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in general-purpose transient voltage suppression applications requiring 160V reverse standoff protection.

The 30KP160CA-TP provides the highest peak pulse power rating at 30kW, suitable for applications requiring maximum energy dissipation. The 20KPA160CA offers an intermediate power rating of 20kW with identical voltage specifications. The 5KP160CA provides a lower power rating of 5kW, appropriate for applications with reduced transient energy levels.

Selection between these parts depends on the specific peak pulse power requirement of the circuit. All parts maintain identical reverse standoff voltage (160V), breakdown voltage range (178V–178.7V), and operating temperature specifications (-55°C ~ 175°C TJ), ensuring functional equivalence for voltage clamping performance. Package variations (R-6 versus P600 axial) are mechanical considerations that do not affect electrical performance in through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 5KP160CA substitute for the 30KP160CA-TP in all applications?

A: The 5KP160CA is electrically equivalent in terms of voltage specifications (160V reverse standoff, 178V breakdown minimum, 259V clamping maximum). However, it has a lower peak pulse power rating of 5kW compared to the 30kW rating of the 30KP160CA-TP. Substitution is valid only if the circuit's transient energy does not exceed the 5kW dissipation capability.

Q: What is the difference between the R-6 and P600 package types?

A: Both R-6 and P600 are axial through-hole packages for TVS diodes. The R-6 package is used on the 30KP160CA-TP, while the P600 package is used on the 20KPA160CA and 5KP160CA. Both packages are mechanically compatible with standard through-hole PCB layouts and do not affect electrical performance.

Q: Are all three parts RoHS3 compliant?

A: Yes, all three parts—30KP160CA-TP, 20KPA160CA, and 5KP160CA—are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What determines whether a part can substitute for the 30KP160CA-TP?

A: Substitution is determined by matching the reverse standoff voltage (160V), breakdown voltage range (178V–178.7V), bidirectional channel count (1), type (Zener TVS), mounting type (through-hole), operating temperature range (-55°C ~ 175°C TJ), and application category (general purpose). Peak pulse power rating and package configuration may vary based on circuit requirements.

Q: Can the 20KPA160CA replace the 30KP160CA-TP?

A: The 20KPA160CA is electrically equivalent in voltage specifications and thermal range. It has a peak pulse power rating of 20kW, which is lower than the 30kW rating of the 30KP160CA-TP. Substitution is valid if the circuit's transient energy requirement does not exceed 20kW.
