Key Parameters

Substitute Part Grouping Explanation

Substitution of the TGL41-13-E3/97 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Unidirectional channel configuration (1 channel required)
• Voltage - Reverse Standoff tolerance range (10.5V nominal)
• Voltage - Clamping specification at peak pulse current (19V maximum)
• Current - Peak Pulse rating (10/1000µs pulse profile: 21.1A minimum)
• Power - Peak Pulse dissipation (400W)
• Package / Case format (DO-213AB, MELF surface mount)
• Operating temperature range (-55°C ~ 150°C)
• Series compatibility (TransZorb®)

The TGL41-13A-E3/97 qualifies as a direct substitute based on these parameters. While minor variations exist in reverse standoff voltage (11.1V vs. 10.5V) and clamping voltage (18.2V vs. 19V), these differences remain within acceptable engineering tolerances for general-purpose TVS applications and do not compromise functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TGL41-13A-E3/97 is the recommended substitute for the obsolete TGL41-13-E3/97. Both components share identical manufacturing origin, series designation, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

Both parts meet identical environmental and regulatory requirements, including operating temperature range (-55°C ~ 150°C), moisture sensitivity classification (MSL 1), and export control designations (ECCN: EAR99, HTSUS: 8541.10.0080).

The electrical parameter variations between the main part and substitute are minor and do not introduce functional incompatibility. The substitute exhibits slightly higher reverse standoff voltage (11.1V vs. 10.5V) and marginally lower clamping voltage (18.2V vs. 19V), with equivalent peak pulse current capability (22A vs. 21.1A). These characteristics remain within the operational envelope for general-purpose transient suppression applications.

Frequently Asked Questions (FAQ)

Q: Can TGL41-13A-E3/97 be used as a direct replacement for TGL41-13-E3/97?

A: Yes. Both components are unidirectional Zener TVS diodes from the same manufacturer and series, with identical package format (DO-213AB, MELF), operating temperature range, and power dissipation rating. Electrical parameters are sufficiently aligned for general-purpose applications.

Q: What are the key differences between these parts?

A: The substitute exhibits a higher reverse standoff voltage (11.1V vs. 10.5V) and lower clamping voltage (18.2V vs. 19V). Peak pulse current is marginally higher (22A vs. 21.1A). These variations are within acceptable tolerances for TVS diode substitution.

Q: Does the packaging differ between the main part and substitute?

A: No. Both components use identical DO-213AB (MELF) surface mount packaging with GL41 supplier device package designation. PCB footprint and assembly compatibility are identical.

Q: Are compliance certifications identical?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, with identical moisture sensitivity classification (MSL 1) and export control designations.

Q: Why is the main part listed as obsolete?

A: The TGL41-13-E3/97 has reached end-of-life status. The TGL41-13A-E3/97 remains in active production, providing continued design support and component availability.

Q: Are there any application restrictions for the substitute?

A: No application restrictions exist based on the provided specifications. Both parts are designated for general-purpose transient voltage suppression. Circuit-level validation should follow standard engineering practice for any component substitution.
