Substitute Part Grouping Explanation
Substitution of the TGL41-36-E3/97 is determined by the following critical electrical and mechanical parameters:
- Unidirectional Channel Configuration: Must remain 1 channel
- Package Type: Must be DO-213AB, MELF surface mount
- Voltage Ratings: Reverse standoff voltage, breakdown voltage, and clamping voltage must fall within acceptable operating ranges for the target application
- Current Handling: Peak pulse current rating must meet or exceed application requirements
- Power Dissipation: Peak pulse power rating must support the transient event
- Temperature Range: Operating temperature range must cover the application environment
- Compliance Standards: RoHS3 compliance and MSL rating must be maintained
The TGL41-36A-E3/97 qualifies as a direct substitute based on matching package configuration, channel count, compliance certifications, and compatible electrical performance within the TransZorb® series.

Engineering Selection Recommendations
The TGL41-36A-E3/97 is the qualified substitute for the obsolete TGL41-36-E3/97. Selection is supported by the following factors:
- Active Product Status: The substitute part is currently in active production, ensuring long-term availability and supply chain continuity.
- Identical Package and Mounting: Both parts use DO-213AB MELF surface mount packaging, enabling direct PCB layout compatibility without redesign.
- Matching Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory and manufacturing requirements.
- Compatible Electrical Performance: The substitute provides equivalent or superior electrical characteristics within the same voltage and current operating envelope, with slightly improved peak pulse current capability (8A vs 7.7A) and marginally lower clamping voltage (49.9V vs 52V).
- Identical Temperature Range: Operating temperature specifications are identical, ensuring thermal performance equivalence across the application environment.
Frequently Asked Questions (FAQ)
Q: Can the TGL41-36A-E3/97 be used as a direct replacement for the TGL41-36-E3/97 without PCB modifications?
A: Yes. Both parts share identical DO-213AB MELF package geometry and surface mount footprints, allowing direct substitution without PCB layout changes.
Q: What are the key electrical differences between these parts?
A: The substitute part (TGL41-36A-E3/97) has a slightly higher reverse standoff voltage (30.8V vs 29.1V), higher breakdown voltage (34.2V vs 32.4V), marginally lower clamping voltage (49.9V vs 52V), and slightly higher peak pulse current capability (8A vs 7.7A). Both maintain 400W peak pulse power rating.
Q: Are there any compliance or certification differences?
A: No. Both parts are ROHS3 compliant with MSL Level 1 rating and identical operating temperature ranges (-55°C to 150°C).
Q: Why is the original part marked as obsolete?
A: The TGL41-36-E3/97 has been discontinued by the manufacturer. The TGL41-36A-E3/97 represents the active production equivalent within the TransZorb® series.
Q: What packaging options are available for the substitute part?
A: The TGL41-36A-E3/97 is available in Tape & Reel (TR) packaging for automated assembly, while maintaining the same DO-213AB MELF component package.
