TGL41-47-E3/97 Equivalent & Substitute Parts

Part Overview

The TGL41-47-E3/97 is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® series. This surface mount component is designed for general-purpose transient voltage protection applications. The device features a 38.1V reverse standoff voltage with a 67.8V maximum clamping voltage and 5.9A peak pulse current capability in a DO-213AB (MELF) package.

The TGL41-47-E3/97 is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring this voltage suppression profile.

• Peak pulse current: 5.9A to 6.2A
• Peak pulse power: 400W
• Operating temperature range: -55°C to 150°C

Mechanical Compatibility Criteria:

• Package: DO-213AB (MELF)
• Mounting: Surface Mount
• Supplier device package: GL41 (DO-213AB)

Compliance Requirements:

• RoHS3 Compliant

The TGL41-47A-E3/97 meets all substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The TGL41-47A-E3/97 is the direct substitute for the obsolete TGL41-47-E3/97. Both components share identical mechanical compatibility, thermal operating range, and compliance certifications (ROHS3 Compliant, MSL 1, REACH Unaffected).

The substitute part carries Active product status, ensuring long-term availability and supply chain continuity. The electrical parameters fall within the acceptable tolerance band for this TVS diode category: reverse standoff voltage increases from 38.1V to 40.2V, clamping voltage decreases from 67.8V to 64.8V, and peak pulse current increases from 5.9A to 6.2A. These variations remain within standard design margins for transient voltage suppression applications.

The TGL41-47A-E3/97 is supplied in Tape & Reel (TR) packaging, which is standard for production volume applications and provides improved handling and automated assembly compatibility compared to bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can the TGL41-47A-E3/97 be used as a direct replacement for the TGL41-47-E3/97?

A: Yes. Both parts are unidirectional Zener TVS diodes in the DO-213AB (MELF) package with identical mounting type and thermal operating range. Electrical parameters are within acceptable tolerance for this product category.

Q: What is the difference in clamping voltage between these parts?

A: The main part (TGL41-47-E3/97) has a maximum clamping voltage of 67.8V, while the substitute (TGL41-47A-E3/97) has a maximum clamping voltage of 64.8V. This 3V difference is within standard design margins for TVS diode applications.

Q: Does the substitute part have better availability?

A: Yes. The TGL41-47A-E3/97 carries Active product status, whereas the original part is classified as Obsolete. This ensures continued availability and supply chain reliability.
