30KP180A-TP Equivalent & Substitute Parts

Part Overview

The 30KP180A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection applications. This axial through-hole component features a 180V reverse standoff voltage with a 290.4V maximum clamping voltage and 30kW peak pulse power rating. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic circuit protection requirements. Substitute parts may be required due to inventory availability, packaging preferences, or specific application performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 30KP180A-TP are qualified based on the following critical parameters that must align for functional equivalence:

• Voltage - Reverse Standoff (Typ): 180V
• Unidirectional Channels: 1
• Mounting Type: Through Hole
• Package / Case: R-6 or P600 Axial
• Type: Zener
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The 30KP180A-TP specifies three qualified substitutes: 5KP180A (Littelfuse Inc.), BZW50-180 (STMicroelectronics), and BZW50-180RL (STMicroelectronics). All three maintain the 180V reverse standoff voltage specification and through-hole axial mounting configuration. Differences in clamping voltage, peak pulse current, and power ratings reflect distinct product series designs within acceptable operational parameters for the 180V protection class.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the 30KP180A-TP. Selection between substitutes depends on application-specific power dissipation requirements and package availability:

The 5KP180A (Littelfuse Inc.) operates at 5kW peak pulse power with a P600 axial package, suitable for applications where the 30kW rating of the primary part exceeds circuit requirements. The BZW50-180 and BZW50-180RL (both STMicroelectronics) also operate at 5kW peak pulse power but maintain the R-6 axial package matching the primary part's form factor. The BZW50-180RL variant offers higher inventory availability (1920 pcs) compared to BZW50-180 (807 pcs).

All substitutes share the 180V reverse standoff voltage and 200V minimum breakdown voltage specification, ensuring consistent transient protection performance within the 180V protection class.

Frequently Asked Questions (FAQ)

Q: Can the 5KP180A substitute for the 30KP180A-TP in high-power transient protection circuits?

A: The 5KP180A operates at 5kW peak pulse power versus the 30KP180A-TP's 30kW rating. Substitution is valid only for applications where peak pulse power requirements do not exceed 5kW. Both parts maintain identical 180V reverse standoff voltage and through-hole mounting configuration.

Q: What is the difference between BZW50-180 and BZW50-180RL?

A: Both parts are electrically identical, featuring 180V reverse standoff voltage, 410V clamping voltage, and 5kW peak pulse power. The primary difference is packaging designation and inventory availability. BZW50-180RL has higher stock (1920 pcs) compared to BZW50-180 (807 pcs).

Q: Are package differences between R-6 and P600 axial formats significant for substitution?

A: Both R-6 and P600 are axial through-hole packages formats. The 5KP180A uses P600 packaging while the 30KP180A-TP and BZW50 series use R-6 packaging. Physical dimensions may differ slightly; verify PCB footprint compatibility before substitution.

Q: Do all substitute parts meet the same temperature operating range?

A: The 30KP180A-TP and 5KP180A specify -55°C to 175°C (TJ) operating temperature. The BZW50-180 and BZW50-180RL do not provide explicit operating temperature specifications in the available data. Confirm temperature requirements with manufacturer datasheets for applications requiring extended temperature operation.

Q: What is the significance of the clamping voltage difference between 290.4V and 410V?

A: The 30KP180A-TP clamps at 290.4V maximum while BZW50 series clamps at 410V. Both maintain the 180V reverse standoff specification. The higher clamping voltage of BZW50 series may result in higher transient voltage peaks reaching protected circuits. Application circuit design determines acceptable clamping voltage limits.
