TLZ6V2C-GS08 Equivalent & Substitute Parts

Part Overview

The TLZ6V2C-GS08 is an active-status Zener diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates at a nominal Zener voltage of 6.2 V with a maximum power dissipation of 500 mW in a surface mount SOD-80 MiniMELF package. The device is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in stock with 1,800 units available.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within the same functional category.

Engineering Selection Recommendations

Both the TLZ6V2C-GS08 and BZV55-B6V2,115 are active-status components with equivalent electrical performance in the 6.2 V, 500 mW Zener diode category. Selection between these parts is based on the following factors:

TLZ6V2C-GS08 (Vishay):

ROHS3 compliance explicitly stated
Tape & Reel packaging for automated assembly
Current inventory: 1,800 units
Operating temperature range: -65°C to 175°C

BZV55-B6V2,115 (NXP):

Specified tolerance: ±2%
Extended operating temperature range: -65°C to 200°C
Bulk packaging configuration
Current inventory: 313,222 units
REACH Unaffected status confirmed

Both components satisfy the core electrical requirements for 6.2 V Zener regulation at 500 mW power dissipation with identical package geometry (SOD-80 MiniMELF). Selection should be based on supply availability, packaging format requirements, and temperature range specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can the BZV55-B6V2,115 directly replace the TLZ6V2C-GS08 in existing designs?

A: Yes. Both components share identical nominal Zener voltage (6.2 V), maximum power dissipation (500 mW), impedance (10 Ohms), reverse leakage current (3 µA @ 4 V), and package type (SOD-80 MiniMELF). The electrical performance and mechanical footprint are equivalent.

Q: What is the difference in operating temperature range between these parts?

A: The TLZ6V2C-GS08 operates from -65°C to 175°C, while the BZV55-B6V2,115 extends to -65°C to 200°C. For applications requiring operation above 175°C, the NXP component provides additional thermal margin.

Q: Are the forward voltage specifications identical?

A: No. The TLZ6V2C-GS08 specifies 1.5 V maximum at 200 mA, while the BZV55-B6V2,115 specifies 900 mV maximum at 10 mA. These are measured under different test conditions and do not indicate incompatibility for Zener regulation applications.

Q: What packaging formats are available for each part?

A: The TLZ6V2C-GS08 is supplied in Tape & Reel (TR) format for automated assembly. The BZV55-B6V2,115 is supplied in Bulk packaging. Both use the same SOD-80 MiniMELF physical package.

Q: Are both parts RoHS and REACH compliant?

A: The TLZ6V2C-GS08 is explicitly ROHS3 compliant. Both components are REACH Unaffected. RoHS compliance status for the BZV55-B6V2,115 is not specified in the provided data.

Q: What is the impedance specification and why does it matter?

A: Both parts specify a maximum impedance (Zzt) of 10 Ohms. This parameter defines the dynamic resistance of the Zener diode and affects voltage regulation performance under load changes. Identical impedance ensures equivalent regulation characteristics.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both components use the DO-213AC MiniMELF package with identical pin configuration and footprint. No PCB layout modifications are required for substitution.
