TISP7240F3SL Equivalent & Substitute Parts

Part Overview

The TISP7240F3SL is a 180V 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 substitute parts necessary for new designs and ongoing production requirements. The part provides transient voltage suppression across three independent elements with a 240V breakover voltage and 5V on-state voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TISP7240F3SL is determined by electrical parameter equivalence across the following criteria:

• Voltage - Breakover: 240V
• Voltage - Off State: 180V
• Voltage - On State: 5V
• Current - Peak Pulse (8/20µs): 175A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Number of Elements: 3
• Capacitance: 39pF

The TISP7240F3DR-S maintains identical electrical performance specifications while differing in mounting technology (surface mount 8-SOIC versus through-hole 3-SIP) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TISP7240F3DR-S provides electrical equivalence to the TISP7240F3SL with the following considerations:

Product Status: The TISP7240F3DR-S is active, ensuring continued availability and manufacturing support, whereas the TISP7240F3SL is obsolete.

Compliance: The TISP7240F3DR-S meets ROHS3 compliance requirements, while the TISP7240F3SL is RoHS non-compliant. For applications subject to RoHS regulations, the TISP7240F3DR-S is the appropriate selection.

Packaging: Selection between these parts depends on circuit board design requirements. The TISP7240F3SL uses through-hole mounting (3-SIP), while the TISP7240F3DR-S uses surface-mount technology (8-SOIC). PCB layout and assembly capabilities determine which package is suitable for a given application.

Frequently Asked Questions (FAQ)

Q: Are the TISP7240F3SL and TISP7240F3DR-S electrically equivalent?

A: Yes. Both parts share identical electrical specifications: 240V breakover voltage, 180V off-state voltage, 5V on-state voltage, 175A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, three elements, and 39pF capacitance.

Q: What is the primary difference between these two parts?

A: The primary differences are mounting technology and product status. The TISP7240F3SL is a through-hole 3-SIP package (obsolete), while the TISP7240F3DR-S is a surface-mount 8-SOIC package (active). The TISP7240F3DR-S also meets ROHS3 compliance.

Q: Can I use the TISP7240F3DR-S as a direct replacement for the TISP7240F3SL?

A: Electrical substitution is valid based on parameter equivalence. However, package differences require PCB redesign. The through-hole 3-SIP footprint cannot be directly replaced with the surface-mount 8-SOIC footprint without circuit board layout modifications.

Q: Which part should I select for new designs?

A: The TISP7240F3DR-S is the appropriate choice for new designs due to its active product status, ROHS3 compliance, and continued manufacturing availability.

Q: Are there any compliance differences I should consider?

A: Yes. The TISP7240F3DR-S is ROHS3 compliant, while the TISP7240F3SL is RoHS non-compliant. Applications subject to RoHS regulations require the TISP7240F3DR-S.
