Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLZ56-GS08 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Zener voltage (Nom): 56 V
• Maximum power dissipation: 500 mW
• Package compatibility: DO-213AC, MINI-MELF, SOD-80

Mechanical Compatibility:

• Surface mount configuration
• Identical package footprint and form factor

Compliance & Certification:

• Active product status
• RoHS3 compliance
• REACH unaffected status
• MSL 1 rating

The BZV55-C56,115 manufactured by NXP Semiconductors satisfies all substitution criteria through matching nominal zener voltage, maximum power rating, and package specification. Both components are surface mount devices in the SOD-80 MiniMELF package with equivalent thermal and environmental ratings.

Engineering Selection Recommendations

TLZ56-GS08 (Vishay General Semiconductor):

• Primary selection for applications requiring explicit RoHS3 compliance documentation
• Active product status with established supply chain (120,180 pcs in stock)
• Specified impedance maximum of 100 Ohms provides tighter regulation characteristics

BZV55-C56,115 (NXP Semiconductors):

• Direct substitute with extended operating temperature range (-65 to 200°C vs. -65 to 175°C)
• Active product status with available inventory (38,254 pcs in stock)
• Suitable for applications where higher temperature operation is required
• Includes ±5% voltage tolerance specification

Both components maintain Active product status, REACH unaffected designation, and unlimited moisture sensitivity rating. Selection between these parts depends on specific application requirements regarding temperature range, impedance characteristics, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can the BZV55-C56,115 directly replace the TLZ56-GS08 in existing circuit designs?

A: Yes. Both components share identical nominal zener voltage (56 V), maximum power dissipation (500 mW), and package specification (SOD-80 MiniMELF). The electrical and mechanical compatibility enables direct substitution without circuit modification.

Q: What is the significance of the impedance difference between these parts?

A: The TLZ56-GS08 specifies maximum impedance of 100 Ohms, while the BZV55-C56,115 specifies 200 Ohms maximum. Lower impedance provides superior voltage regulation under load transients. Applications requiring tighter regulation should prioritize the TLZ56-GS08 specification.

Q: Are there temperature range considerations for substitution?

A: The BZV55-C56,115 operates to 200°C maximum, compared to 175°C for the TLZ56-GS08. Applications operating near the upper temperature limit should use the NXP component. Standard applications within -65 to 175°C range are compatible with either part.

Q: Do both parts meet the same compliance standards?

A: Both components are REACH unaffected and maintain MSL 1 (unlimited) moisture sensitivity rating. The TLZ56-GS08 explicitly specifies RoHS3 compliance. Verify compliance documentation with NXP for the BZV55-C56,115 if RoHS3 certification is a design requirement.

Q: What is the package compatibility between these zener diodes?

A: Both the TLZ56-GS08 and BZV55-C56,115 use identical package specifications: DO-213AC, MINI-MELF, SOD-80. PCB footprints and land patterns are interchangeable without layout modification.

Q: How do the reverse leakage current specifications compare?

A: The TLZ56-GS08 specifies 40 nA maximum at 50.4 V, while the BZV55-C56,115 specifies 50 nA maximum at 39.2 V. Both values are within acceptable ranges for typical zener diode applications. The measurement conditions differ, reflecting manufacturer test protocols.
