TZM5232C-GS08 Equivalent & Substitute Parts

Part Overview

The TZM5232C-GS08 is a Zener diode rated at 5.6 V nominal with 500 mW power dissipation in a surface mount SOD-80 MiniMELF package. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement. The part is manufactured by Vishay General Semiconductor - Diodes Division and complies with ROHS3 and REACH standards.

Substitute Part Grouping Explanation

Substitution of the TZM5232C-GS08 is determined by the following critical parameters:

Zener Voltage (Vz): Must be 5.6 V nominal to maintain circuit voltage regulation specifications
Power Rating: Must be 500 mW to ensure adequate thermal performance in the application
Package Type: Must be SOD-80 MiniMELF to ensure mechanical and electrical compatibility with existing PCB layouts
Mounting Type: Must be surface mount to maintain assembly process compatibility
Reverse Leakage Current: Must be 5 µA @ 3 V to meet circuit performance requirements
Forward Voltage: Must be 1.1 V @ 200 mA maximum to ensure consistent circuit behavior

The TZM5232B-GS08 qualifies as a direct substitute based on these parameters. While the tolerance specification differs (±5% versus ±2%), all critical electrical and mechanical parameters remain equivalent, and the part is currently in active production status.

Engineering Selection Recommendations

The TZM5232B-GS08 is the direct substitute for the obsolete TZM5232C-GS08. Selection of the substitute part is based on the following factors:

Product Status: The TZM5232C-GS08 is obsolete, while the TZM5232B-GS08 is in active production. This ensures long-term availability and supply chain continuity.

Electrical Equivalence: Both parts maintain identical nominal Zener voltage (5.6 V), power rating (500 mW), reverse leakage current (5 µA @ 3 V), and forward voltage characteristics (1.1 V @ 200 mA). The tolerance difference (±5% versus ±2%) does not affect functional substitution in applications where the original ±2% tolerance was not a critical design requirement.

Mechanical Compatibility: Both parts use the SOD-80 MiniMELF package with identical pinout and footprint, ensuring direct PCB compatibility without layout modifications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Packaging Availability: The TZM5232B-GS08 is supplied in Tape & Reel format with 30,400 pieces in stock, providing reliable procurement compared to the limited inventory of the obsolete part.

Frequently Asked Questions (FAQ)

Q: Can the TZM5232B-GS08 be used as a direct replacement for the TZM5232C-GS08?

A: Yes. Both parts share identical Zener voltage (5.6 V), power rating (500 mW), package type (SOD-80 MiniMELF), and critical electrical characteristics. The TZM5232B-GS08 is the manufacturer-recommended substitute.

Q: What is the difference between the ±2% tolerance of the TZM5232C-GS08 and the ±5% tolerance of the TZM5232B-GS08?

A: The tolerance specification indicates the allowable deviation from the nominal 5.6 V Zener voltage. The TZM5232C-GS08 allows ±0.112 V deviation, while the TZM5232B-GS08 allows ±0.28 V deviation. Applications requiring tighter voltage regulation should evaluate whether the ±5% tolerance meets circuit specifications.

Q: Are the packages physically identical?

A: Yes. Both parts use the DO-213AC, MINI-MELF, SOD-80 package with identical dimensions and pinout. No PCB layout modifications are required for substitution.

Q: What is the reverse leakage current specification?

A: Both parts specify 5 µA maximum reverse leakage current measured at 3 V reverse bias. This parameter is identical between the two parts.

Q: Are there any compliance or regulatory differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical environmental certifications. Both have Moisture Sensitivity Level 1 (Unlimited).

Q: Why is the TZM5232C-GS08 listed as obsolete?

A: The TZM5232C-GS08 has been discontinued by the manufacturer. The TZM5232B-GS08 remains in active production and is the current equivalent offering.

Q: What is the maximum operating temperature for both parts?

A: The TZM5232C-GS08 specifies 175°C maximum operating temperature. The TZM5232B-GS08 does not provide an explicit operating temperature specification in the available data.

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

A: Yes. The TZM5232B-GS08 is suitable for both replacement of obsolete units and new design implementations. The active production status ensures ongoing availability.
