TISP7150F3SL Equivalent & Substitute Parts

Part Overview

The TISP7150F3SL is a 120V off-state, 175A peak pulse (8/20µs) transient voltage suppressor thyristor manufactured by Bourns Inc. in a 3-SIP through-hole package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The part provides transient voltage suppression across three independent elements with 47pF capacitance per element and a 150mA hold current specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TISP7150F3SL is determined by electrical parameter equivalence across the following critical specifications:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current handling (both 8/20µs and 10/1000µs waveforms)
• Hold current threshold
• Number of protection elements (3-element configuration)
• Capacitance per element

The TISP7150F3DR-S maintains identical electrical performance across all these parameters. The primary difference is packaging: the substitute transitions from through-hole (3-SIP) to surface-mount (8-SOIC) technology. This substitution is valid only when the target application can accommodate surface-mount assembly.

Parameter Comparison

Engineering Selection Recommendations

The TISP7150F3DR-S is the direct electrical equivalent to the TISP7150F3SL. Selection between these parts depends on application constraints:

For new designs and production requiring modern compliance standards, the TISP7150F3DR-S is preferred. It maintains active product status with Bourns Inc. and achieves ROHS3 compliance, whereas the original part is obsolete and RoHS non-compliant.

For applications with existing through-hole PCB layouts, the TISP7150F3SL footprint cannot be directly replaced without board redesign. The TISP7150F3DR-S requires surface-mount assembly capability and PCB layout modification to accommodate the 8-SOIC package.

Both parts share identical electrical performance, moisture sensitivity rating, and regulatory classifications (REACH Unaffected, EAR99 ECCN).

Frequently Asked Questions (FAQ)

Q: Can the TISP7150F3DR-S directly replace the TISP7150F3SL on existing PCBs?

A: No. The TISP7150F3SL uses a 3-SIP through-hole package, while the TISP7150F3DR-S uses an 8-SOIC surface-mount package. PCB layout and assembly process modifications are required.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts share identical voltage ratings (150V breakover, 120V off-state, 5V on-state), peak pulse current ratings (175A at 8/20µs, 45A at 10/1000µs), hold current (150mA), element count (3), and capacitance (47pF).

Q: Why is the TISP7150F3SL marked as obsolete?

A: The TISP7150F3SL is classified as obsolete by Bourns Inc. The TISP7150F3DR-S represents the current active product line for this electrical specification.

Q: What are the compliance differences between these parts?

A: The TISP7150F3DR-S is ROHS3 compliant, while the TISP7150F3SL is RoHS non-compliant. Both maintain REACH Unaffected status and share the same EAR99 ECCN classification.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
