TLZ36-GS08 Equivalent & Substitute Parts

Part Overview

The TLZ36-GS08 is a Zener diode rated at 36 V nominal voltage with 500 mW maximum power dissipation in a surface mount SOD-80 (DO-213AC, MINI-MELF) package. Manufactured by Vishay General Semiconductor - Diodes Division, this component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs while maintaining functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitution of the TLZ36-GS08 is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

Zener voltage nominal rating: 36 V
Maximum power dissipation: 500 mW
Package type: SOD-80 (DO-213AC, MINI-MELF)
Mounting configuration: Surface Mount

Acceptable Variation Parameters:

Zener voltage tolerance: Specified tolerance values are permitted
Impedance (Zzt): Maximum impedance values within acceptable circuit performance limits
Forward voltage (Vf): Specified maximum values at rated current
Operating temperature range: Extended ranges are acceptable
Reverse leakage current: When specified, values within design margins are acceptable

The substitute part CLL5258B TR TIN/LEAD meets all critical matching parameters and operates within acceptable electrical variation limits for direct substitution in 36 V Zener diode applications.

Engineering Selection Recommendations

TLZ36-GS08 (Vishay General Semiconductor):

Primary selection for applications requiring ROHS3 compliance
Active product status with established supply chain
Specified for designs with strict RoHS certification requirements
Forward voltage specification of 1.5 V @ 200 mA

CLL5258B TR TIN/LEAD (Central Semiconductor):

Direct functional substitute with equivalent 36 V, 500 mW ratings
Superior impedance specification (70 Ohms vs. 75 Ohms maximum)
Lower forward voltage (1.25 V @ 200 mA) provides improved efficiency characteristics
Extended operating temperature range (-65°C to 200°C vs. -65°C to 175°C)
RoHS non-compliant status requires verification against design compliance requirements
±5% zener voltage tolerance provides specified accuracy
Suitable for applications where RoHS3 compliance is not mandated

Both parts are classified as Active products with REACH Unaffected status and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can CLL5258B TR TIN/LEAD replace TLZ36-GS08 in all applications?

A: Functional substitution is valid for 36 V Zener diode applications where the electrical parameters align. The primary consideration is RoHS compliance status. TLZ36-GS08 is ROHS3 compliant; CLL5258B TR is RoHS non-compliant. Design compliance requirements must be verified before substitution.

Q: What are the key electrical differences between these parts?

A: Both parts share identical nominal Zener voltage (36 V) and maximum power rating (500 mW). CLL5258B TR offers lower impedance (70 Ohms vs. 75 Ohms) and lower forward voltage (1.25 V vs. 1.5 V @ 200 mA). CLL5258B TR includes specified ±5% Zener voltage tolerance and extended temperature range to 200°C.

Q: Are the packages physically identical?

A: Yes. Both parts use SOD-80 (DO-213AC, MINI-MELF) surface mount packages with identical mechanical dimensions and land pattern compatibility.

Q: What is the impact of impedance difference on circuit performance?

A: Impedance (Zzt) affects dynamic resistance and voltage regulation characteristics. CLL5258B TR's lower maximum impedance (70 Ohms) provides tighter voltage regulation compared to TLZ36-GS08 (75 Ohms). This difference is within typical circuit design margins for 36 V Zener applications.

Q: Does forward voltage difference affect circuit design?

A: Forward voltage specifications apply to forward-biased diode operation. In Zener regulation circuits, the diode operates in reverse bias. Forward voltage differences are not relevant to Zener regulation performance but may affect circuits using the diode in forward-conducting mode.

Q: What is the significance of the extended temperature range in CLL5258B TR?

A: CLL5258B TR operates to 200°C maximum versus 175°C for TLZ36-GS08. This extended range provides design flexibility for high-temperature applications. Both parts maintain -65°C minimum operating temperature.

Q: How does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory and design requirement determined by end-product application and market destination. TLZ36-GS08 ROHS3 compliance is mandatory for applications subject to RoHS directives. CLL5258B TR RoHS non-compliance requires explicit design approval before substitution in regulated applications.
