30KPA60C-B Equivalent & Substitute Parts

Part Overview

The 30KPA60C-B is a bidirectional Zener transient voltage suppressor (TVS) diode manufactured by Littelfuse, rated for 60V reverse standoff voltage with a 107.1V maximum clamping voltage at peak pulse current. This component is designed for general-purpose transient voltage suppression in through-hole P600 axial package configuration. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring similar electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 30KPA60C-B is determined by the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 60V with breakdown minimum of 63.32V or higher
• Clamping Voltage: Maximum clamping voltage at peak pulse current must not exceed 107.1V to maintain circuit protection integrity
• Peak Pulse Power: 30000W (30kW) rating for equivalent energy dissipation capability
• Package Configuration: Through-hole axial mounting (P600 or R-6 packages acceptable)
• Operating Temperature: -55°C to 175°C junction temperature range
• Compliance: ROHS3 compliance required

Substitute parts are grouped into two categories based on these parameters: direct equivalents with identical electrical specifications and active-status alternatives with compatible electrical performance within the defined parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (30kW Power Rating)

The 30KPA60CA and 30KPA60CA-B are direct functional equivalents to the 30KPA60C-B. Both maintain the 30000W peak pulse power rating, 297.1A peak pulse current, and P600 axial package configuration. The 30KPA60CA-B from Littelfuse is the preferred substitute, as it maintains manufacturer continuity while offering active product status. The 30KPA60CA from MDE Semiconductor Inc provides an alternative source with identical electrical specifications. Both parts are ROHS3 compliant and operate across the full -55°C to 175°C temperature range.

The 30KP60CA-TP from Micro Commercial Co maintains the 30000W power rating and 60V voltage class but uses the R-6 axial package instead of P600. This part is suitable for applications where package footprint differences are acceptable.

Secondary Substitutes (15kW Power Rating)

The 15KPA60CAE3/TR13 from Microchip Technology and 15KP60CA-TP from Micro Commercial Co operate at half the peak pulse power rating (15000W) compared to the main part. These parts are suitable only for applications where transient energy levels do not exceed 15kW. Both maintain the 60V voltage class and -55°C to 175°C operating temperature range. The 15KPA60CAE3/TR13 uses the P600 package, while the 15KP60CA-TP uses the R-6 package.

All substitute parts carry ROHS3 compliance and are currently in active production status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 30KPA60CA-B directly replace the 30KPA60C-B without circuit modifications?

A: Yes. The 30KPA60CA-B is a direct functional equivalent with identical voltage ratings (60V reverse standoff), clamping voltage (102V maximum), peak pulse power (30000W), and package configuration (P600 axial). Both parts operate across -55°C to 175°C and are ROHS3 compliant. No circuit modifications are required.

Q: What is the difference between the P600 and R-6 axial packages?

A: Both P600 and R-6 are through-hole axial package configurations for TVS diodes. The primary difference is physical dimensions and lead spacing. Parts using R-6 packages (15KP60CA-TP and 30KP60CA-TP) may require PCB layout adjustments if the original design was optimized for P600 spacing. Electrical performance is equivalent.

Q: Can I use the 15KPA60CAE3/TR13 or 15KP60CA-TP as substitutes?

A: These parts are suitable only if your application's transient energy requirements do not exceed 15000W peak pulse power. The 30KPA60C-B is rated for 30000W, which is twice the power dissipation capability. Using a 15kW-rated part in a 30kW application will result in inadequate transient suppression and potential component failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the environmental and regulatory requirements of the 30KPA60C-B.

Q: What is the inventory status of substitute parts?

A: The 30KPA60CA-B (645 pcs), 30KPA60CA (1583 pcs), 15KPA60CAE3/TR13 (682 pcs), 15KP60CA-TP (978 pcs), and 30KP60CA-TP (811 pcs) are all listed as new original stock in inventory. The main part 30KPA60C-B (967 pcs) remains available despite obsolete status.

Q: Does clamping voltage variation affect circuit protection?

A: Clamping voltage differences within the specified range affect transient suppression characteristics. The 30KPA60C-B clamps at 107.1V maximum, while the 30KPA60CA and 30KPA60CA-B clamp at 102V maximum. Lower clamping voltage provides tighter transient suppression. The 15kW-rated parts clamp at 97.3V to 97.4V. Select based on your circuit's maximum allowable transient voltage threshold.
