Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PESD1LIN,115 is determined by the following critical parameters:

Primary Substitution Criteria:

• Package / Case: SOD-323 (SC-76) surface mount only
• Type: Zener diode topology
• Bidirectional Channels: Single channel configuration
• Voltage - Reverse Standoff: 15V or 24V rating
• Voltage - Clamping (Max) @ Ipp: Must accommodate 44V or 70V clamping range
• Current - Peak Pulse (8/20µs): Minimum 3A capability
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Grouping Logic: Substitute parts are grouped by voltage rating compatibility. Parts with 15V or 24V reverse standoff ratings and SOD-323 packaging are considered functionally equivalent. Clamping voltage performance, peak pulse current capability, and power dissipation characteristics determine the degree of substitution suitability within each voltage class.

Parameter Comparison

Engineering Selection Recommendations

Automotive-Grade Substitutes (AEC-Q101 Qualified):

ESDLIN1524BJ and ESDLIN1524BJ-HQ (STMicroelectronics) are active automotive-grade alternatives with AEC-Q101 qualification matching the original part's automotive requirements. ESDLIN1524BJ provides dual voltage ratings (15V/24V) with clamping voltages of 35V and 50V, maintaining functional compatibility. ESDLIN1524BJ-HQ operates at 50V reverse standoff with 40V clamping and 50A peak pulse current, suitable for higher-current applications.

SP4024-01FTG-C (Littelfuse Inc.) is an active automotive-grade part with AEC-Q101 qualification, 24V reverse standoff, 50V clamping, and 7A peak pulse current. This part uses steering diode topology rather than Zener, offering alternative transient suppression characteristics.

PJEC2415VM1WS-AU_R1_000A1 (Panjit International Inc.) is an active automotive-grade part with AEC-Q101 qualification, 24V reverse standoff, 35V clamping, and 5A peak pulse current. Package variant is SC-90 SOD-323F.

Industrial-Grade Substitutes (Active Status):

CDSOD323-T24C, CDSOD323-T24C-DSL, CDSOD323-T24LC, and CDSOD323-T24SC (Bourns Inc.) are active industrial-grade alternatives with 24V reverse standoff ratings. These parts feature higher peak pulse currents (6A to 9A) and increased power dissipation (250W to 400W) compared to the original part. CDSOD323-T24LC is specified for HDMI and USB OTG applications with 1pF capacitance.

SD24C.TCT (Semtech Corporation) is an active industrial-grade part with 24V reverse standoff, 44V clamping, and 8A peak pulse current, matching the original part's 44V clamping specification.

Product Status Consideration:

All substitute parts listed maintain active product status, ensuring ongoing availability and manufacturing support. The original PESD1LIN,115 is classified as "Not For New Designs," making active substitutes necessary for production continuity.

Frequently Asked Questions (FAQ)

Q: Can ESDLIN1524BJ-HQ replace PESD1LIN,115 directly?

A: ESDLIN1524BJ-HQ operates at 50V reverse standoff, which exceeds the original part's 15V/24V rating. While both are SOD-323 packaged and AEC-Q101 qualified, the higher voltage rating makes this suitable only for applications requiring higher voltage protection. Verify circuit requirements before substitution.

Q: What is the difference between CDSOD323-T24C and CDSOD323-T24C-DSL?

A: Both parts are manufactured by Bourns Inc. with identical electrical specifications (24V reverse standoff, 56V clamping, 6A peak pulse current). The primary difference is packaging: CDSOD323-T24C is supplied in Cut Tape & Digi-Reel format, while CDSOD323-T24C-DSL is supplied in Tape & Reel format.

Q: Are Bourns CDSOD323 series parts suitable for automotive applications?

A: Bourns CDSOD323 series parts are industrial-grade components without automotive qualification. They are not AEC-Q101 certified. For automotive applications requiring AEC-Q101 qualification, use ESDLIN1524BJ, ESDLIN1524BJ-HQ, SP4024-01FTG-C, or PJEC2415VM1WS-AU_R1_000A1.

Q: What does "Steering (Rail to Rail)" mean for SP4024-01FTG-C?

A: SP4024-01FTG-C uses steering diode topology rather than traditional Zener diode design. This topology provides transient suppression with different clamping characteristics and is suitable for rail-to-rail protection in digital circuits.

Q: Can I use a substitute part with higher peak pulse current than the original?

A: Yes. Parts with higher peak pulse current ratings (such as CDSOD323-T24SC at 9A versus the original 3A) provide equivalent or superior protection. Higher current capability does not compromise circuit compatibility; it indicates greater transient suppression capacity.

Q: What is the significance of capacitance differences between substitute parts?

A: Capacitance values range from 1pF to 50pF at 1MHz. Lower capacitance (1pF to 3pF) is preferred for high-frequency signal integrity applications. Higher capacitance (40pF to 50pF) may introduce signal distortion in high-speed circuits. Select based on circuit frequency requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance.
