PTVS3-076C Equivalent & Substitute Parts

Part Overview

The PTVS3-076C is a transient voltage suppressor (TVS) diode manufactured by Bourns Inc., designed for general-purpose overvoltage protection applications. This axial through-hole component features a 76V reverse standoff voltage and 140V maximum clamping voltage with 3000A peak pulse current capability. The PTVS3-076C is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PTVS3-076C is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 76V (Max)
• Voltage - Breakdown (Min): 85V
• Voltage - Clamping (Max) @ Ipp: 140V
• Current - Peak Pulse (10/1000µs): 3000A (3kA) (8/20µs)
• Capacitance @ Frequency: 1700pF @ 10kHz
• Mounting Type: Through Hole
• Package / Case: Axial, Right Angle Bend (24.15mm Center)
• Bidirectional Channels: 1

The PTVS3-076C-TH is the direct active equivalent from Bourns Inc., maintaining identical electrical specifications and mechanical form factor while offering improved product status and availability.

Parameter Comparison

Engineering Selection Recommendations

The PTVS3-076C-TH is the primary substitute for the obsolete PTVS3-076C. Both components maintain identical electrical performance across all critical transient voltage suppression parameters and share the same mechanical form factor. The PTVS3-076C-TH carries active product status, ensuring continued manufacturing support and supply chain availability.

Both parts meet ROHS3 compliance requirements. The PTVS3-076C-TH operates within a maximum junction temperature range of -55°C to 125°C, compared to the original part's -55°C to 150°C range. For applications requiring the full 150°C upper temperature limit, this difference must be evaluated against specific circuit operating conditions.

Frequently Asked Questions (FAQ)

Q: Can PTVS3-076C-TH be used as a direct replacement for PTVS3-076C?

A: Yes. The PTVS3-076C-TH provides electrical equivalence across all critical parameters: 76V reverse standoff voltage, 85V minimum breakdown voltage, 140V maximum clamping voltage, and 3000A peak pulse current. The mechanical form factor and through-hole axial package are identical.

Q: What is the difference between PTVS3-076C and PTVS3-076C-TH?

A: The primary differences are product status and operating temperature range. PTVS3-076C is obsolete; PTVS3-076C-TH is active. PTVS3-076C-TH operates to 125°C junction temperature versus 150°C for the original part. Packaging differs: PTVS3-076C ships in bulk; PTVS3-076C-TH ships in trays.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. PTVS3-076C is REACH Unaffected; PTVS3-076C-TH is REACH Affected. Both carry EAR99 export classification.

Q: Does the operating temperature difference affect general-purpose applications?

A: The 25°C reduction in maximum junction temperature (from 150°C to 125°C) applies only to applications operating at the upper thermal limit. For standard general-purpose overvoltage protection, this difference is not functionally significant.

Q: Can the packaging format be mixed in production?

A: PTVS3-076C-TH is supplied in trays, while PTVS3-076C was supplied in bulk. Tray packaging provides improved component protection and handling efficiency for automated assembly processes.
