SA130C Transient Voltage Suppressor (TVS) Diode - Equivalent & Substitute Parts

Part Overview

The SA130C is a bidirectional Zener TVS diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage suppression in through-hole applications. The device features a 130V reverse standoff voltage with a 219.45V maximum clamping voltage and 2.4A peak pulse current capability in a DO-204AC (DO-15) axial package. The SA130C is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SA130C is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 130V (primary voltage rating)
• Voltage - Clamping (Max) @ Ipp: 209V to 219.45V (acceptable range for transient suppression)
• Current - Peak Pulse (10/1000µs): 2.4A to 2.5A (peak pulse handling capability)
• Power - Peak Pulse: 500W (thermal dissipation capacity)
• Package / Case: DO-204AC, DO-15, Axial (mechanical and electrical compatibility)
• Mounting Type: Through Hole (board integration requirement)
• Operating Temperature Range: -55°C minimum to 175°C maximum (thermal operating envelope)

All substitute parts maintain identical or tighter specifications within these parameters. Substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status, providing superior supply chain continuity compared to the obsolete SA130C. Selection among substitute options should be based on the following criteria:

SA130CA (Taiwan Semiconductor Corporation): Active product with ROHS3 compliance and REACH Unaffected status. Offers 2.5A peak pulse current, providing 4% higher current handling than the original SA130C. Suitable for applications requiring maximum current margin within the 130V rating class.

P5KE130CA-TP (Micro Commercial Co): Active product with extended operating temperature range (-65°C to 175°C), providing 10°C lower minimum temperature specification. Maintains 2.4A peak pulse current matching the original SA130C. Appropriate for applications requiring enhanced low-temperature performance.

SA130CA-AP, SA130CA-BP, SA130CA-TP (Micro Commercial Co): All three variants are active products with identical electrical specifications (2.4A peak pulse, 209V clamping voltage, -55°C to 175°C operating range). Differentiation is based on packaging and distribution channel. All maintain REACH Unaffected compliance status.

All substitute parts maintain the critical 130V reverse standoff voltage, 500W peak pulse power rating, and DO-204AC through-hole package compatibility required for direct functional replacement of the SA130C.

Frequently Asked Questions (FAQ)

Q: Can SA130CA be used as a direct replacement for SA130C?

A: Yes. SA130CA maintains identical reverse standoff voltage (130V), peak pulse power (500W), and package configuration (DO-204AC, DO-15, Axial). The clamping voltage is 209V versus 219.45V in the original, representing a 4.7% reduction within acceptable transient suppression parameters. Peak pulse current is 2.5A versus 2.4A, providing additional margin.

Q: What is the difference between P5KE130CA-TP and SA130CA variants?

A: P5KE130CA-TP extends the minimum operating temperature to -65°C compared to -55°C for SA130CA variants. All other electrical parameters are equivalent. Selection depends on whether the application requires the extended low-temperature specification.

Q: Are SA130CA-AP, SA130CA-BP, and SA130CA-TP electrically identical?

A: Yes. All three variants share identical electrical specifications: 130V reverse standoff, 209V clamping voltage, 2.4A peak pulse current, and 500W peak pulse power. Differences are limited to packaging format and distribution channel designation.

Q: Does the 10V reduction in clamping voltage (209V vs 219.45V) affect circuit protection?

A: No. The clamping voltage reduction of 10V represents a 4.7% change and remains within the functional tolerance for general-purpose transient voltage suppression at the 130V rating class. Both values suppress transient overvoltage to safe levels for protected circuitry.

Q: Are all substitute parts RoHS and REACH compliant?

A: SA130CA is ROHS3 Compliant and REACH Unaffected. P5KE130CA-TP, SA130CA-AP, SA130CA-BP, and SA130CA-TP are all REACH Unaffected. RoHS compliance status for Micro Commercial Co variants is not specified in the provided data.

Q: What inventory levels are available for each substitute part?

A: SA130CA: 970 Pcs. P5KE130CA-TP: 842 Pcs. SA130CA-AP: 913 Pcs. SA130CA-BP: 744 Pcs. SA130CA-TP: 1040 Pcs. All parts are listed as new original stock.
