TISP7260F3SL Equivalent & Substitute Parts

Part Overview

The TISP7260F3SL is a 200V off-state, 175A peak pulse (8/20µs) transient voltage suppressor thyristor manufactured by Bourns Inc. in a 3-SIP through-hole package configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part's primary function is transient voltage suppression in power distribution and protection circuits where high peak current handling and fast response characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TISP7260F3SL is determined by electrical parameter equivalence across the following criteria:

• Voltage ratings: Breakover voltage (260V), off-state voltage (200V), and on-state voltage (5V) must match exactly
• Current handling: Peak pulse current at 8/20µs (175A) and 10/1000µs (45A) specifications must be identical
• Holding current (Ih): 150mA requirement must be maintained
• Element count: 3-element configuration must be preserved
• Capacitance: 39pF specification must be matched
• Base product series: TISP72 family designation

The TISP7260F3DR-S qualifies as a functional equivalent based on identical electrical performance across all specified parameters. The primary distinction is packaging and mounting technology: the substitute transitions from through-hole (3-SIP) to surface-mount (8-SOIC) configuration.

Parameter Comparison

Engineering Selection Recommendations

The TISP7260F3DR-S provides electrical equivalence to the obsolete TISP7260F3SL across all specified transient voltage suppression parameters. Selection between these parts depends on application constraints:

For through-hole PCB implementations, the TISP7260F3SL remains available in current inventory (783 pcs). However, given obsolete product status, long-term availability cannot be assured.

For new designs or redesigns accommodating surface-mount technology, the TISP7260F3DR-S is the preferred selection. This part maintains active product status with higher inventory availability (5040 pcs) and meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant.

Both parts share identical electrical performance and are manufactured by Bourns Inc. within the TISP72 base product family. PCB layout and assembly process modifications are required when transitioning from 3-SIP through-hole to 8-SOIC surface-mount packaging.

Frequently Asked Questions (FAQ)

Q: Can TISP7260F3DR-S directly replace TISP7260F3SL in existing through-hole designs?

A: Electrical performance is identical. Physical replacement requires PCB redesign and assembly process modification due to different mounting technologies (through-hole versus surface-mount) and package footprints (3-SIP versus 8-SOIC).

Q: What are the key electrical parameters that define substitution eligibility?

A: Breakover voltage (260V), off-state voltage (200V), on-state voltage (5V), peak pulse current at 8/20µs (175A), peak pulse current at 10/1000µs (45A), holding current (150mA), element count (3), and capacitance (39pF) must all match exactly.

Q: Why is the TISP7260F3SL classified as obsolete?

A: Product status reflects manufacturer discontinuation. The TISP7260F3DR-S represents the active-status successor within the TISP72 family.

Q: Are there compliance differences between these parts?

A: Yes. TISP7260F3DR-S is ROHS3 compliant, while TISP7260F3SL is RoHS non-compliant. Both are REACH unaffected and classified under ECCN EAR99.

Q: What inventory considerations apply?

A: TISP7260F3SL has 783 pcs available. TISP7260F3DR-S has 5040 pcs available in tape and reel packaging. Obsolete status may affect future TISP7260F3SL availability.
