TZMC75-GS18 Equivalent & Substitute Parts

Part Overview

The TZMC75-GS18 is an automotive-grade Zener diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at a nominal Zener voltage of 75 V with 500 mW power dissipation capability in a SOD-80 MiniMELF package. The device is AEC-Q101 qualified and RoHS3 compliant, making it suitable for automotive and industrial applications requiring voltage regulation and transient protection.

Equivalent and substitute parts are identified when designs require alternative sourcing, higher inventory availability, or modified tolerance specifications while maintaining functional compatibility within the same electrical and mechanical parameters.

Engineering Selection Recommendations

TZMC75-GS18 (Primary Part)

The TZMC75-GS18 is the primary reference component with ±5% tolerance specification. This part is actively manufactured and maintains automotive-grade AEC-Q101 qualification. Current inventory of 826 pieces supports immediate availability for production requirements.

TZMC75-GS08 (Direct Substitute)

The TZMC75-GS08 is a direct parametric equivalent with identical electrical and mechanical specifications to the TZMC75-GS18. Both parts share the same ±5% tolerance rating and are manufactured within the same TZM series. The primary distinction is packaging configuration (GS08 versus GS18 tape reel format). This part maintains 6,423 units in inventory and is suitable for direct substitution in applications where tape reel format compatibility is acceptable.

TZMB75-GS08 (Tighter Tolerance Equivalent)

The TZMB75-GS08 provides an enhanced tolerance specification of ±2% compared to the ±5% tolerance of the TZMC75-GS18. All other electrical parameters, mechanical specifications, and compliance certifications remain identical. This part is manufactured within the TZM series and carries the same AEC-Q101 automotive qualification. The TZMB75-GS08 is suitable for applications requiring improved voltage regulation accuracy. Inventory availability is 17,544 units.

All three parts are RoHS3 compliant, AEC-Q101 qualified, and rated for automotive-grade operation across the -65°C to 175°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can TZMC75-GS08 be used as a direct replacement for TZMC75-GS18?

A: Yes. Both parts share identical electrical specifications (75 V nominal, 500 mW, ±5% tolerance) and mechanical packaging (SOD-80 MiniMELF surface mount). The primary difference is the tape reel format designation. Functional performance and compliance certifications are equivalent.

Q: What is the difference between TZMC75-GS18 and TZMB75-GS08?

A: The TZMB75-GS08 features a ±2% tolerance specification compared to the ±5% tolerance of TZMC75-GS18. All other parameters including voltage, power rating, impedance, leakage current, and operating temperature range are identical. The TZMB75-GS08 is suitable for applications requiring tighter voltage regulation accuracy.

Q: Are all substitute parts AEC-Q101 qualified?

A: Yes. TZMC75-GS08 and TZMB75-GS08 both carry AEC-Q101 automotive qualification, matching the TZMC75-GS18 specification.

Q: Can these parts be used interchangeably in automotive applications?

A: Yes, provided the application tolerance requirements are met. For designs requiring ±5% tolerance, TZMC75-GS18 and TZMC75-GS08 are interchangeable. For designs requiring ±2% tolerance, TZMB75-GS08 is the appropriate selection.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are RoHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for these Zener diodes?

A: All three parts operate across -65°C to 175°C, supporting automotive and industrial temperature extremes.

Q: Can the SOD-80 MiniMELF package be used on standard PCB assembly equipment?

A: Yes. The SOD-80 MiniMELF package is a standard surface mount package compatible with automated PCB assembly processes.
