It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-47-E3/97 datasheet, TGL41-47-E3/97 pinout, TGL41-47-E3/97 application, or TGL41-47-E3/97 equivalent, key selection criteria include clamping voltage (64.8 V at 6.2 A), stand-off voltage (40.2 V), unidirectional polarity, MELF package suitability for automated placement, and RoHS-compliant E3/97 tape-and-reel packaging.
Technical Context
This TVS diode employs a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max forward voltage at 25 A, enabling use in DC-biased protection paths where reverse blocking is required.
The device operates across -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (peak reflow 250 °C). Its DO-213AB package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43A | DO-214AA (SMB) package; 43 V VWM, 69.4 V VC @ 5.8 A; 600 W PPPM | Higher clamping voltage and larger footprint; suited for higher-power board-level protection with heatsinking. | Select SMBJ43A when PCB space allows larger package and system requires >600 W surge handling with thermal relief. |
| 1.5KE43A | DO-201AD (Axial) package; 43 V VWM, 69.4 V VC @ 5.8 A; 1500 W PPPM | Through-hole mounting; higher peak power but slower response due to lead inductance; not suitable for high-frequency transients. | Choose 1.5KE43A for cost-sensitive, non-SMT legacy designs where axial insertion is acceptable and sub-100 ns response is not critical. |
Compared with SMBJ43A and 1.5KE43A, TGL41-47-E3/97 offers superior high-frequency transient response and compact MELF form factor for dense SMT layouts, while delivering precise 40.2 V stand-off and 64.8 V clamping optimized for 48 V-class DC systems.

FAQ
What is the clamping voltage of the TGL41-47-E3/97 and how is it measured?
The TGL41-47-E3/97 has a maximum clamping voltage (VC) of 64.8 V, measured at its rated peak pulse current (IPPM) of 6.2 A using a 10/1000 μs waveform per IEC 61000-4-5. This value represents the highest voltage the device allows across its terminals during a standardized surge event, directly defining the protection level for downstream components connected to the same node as the TGL41-47-E3/97.
Is the TGL41-47-E3/97 suitable for bidirectional transient protection?
No, the TGL41-47-E3/97 is strictly unidirectional, as confirmed by Vishay documentation stating "Available in uni-directional polarity only" and specifying cathode marking via blue band. It conducts only when anode-to-cathode voltage exceeds VBR; reverse polarity transients require a separate device or a dedicated bidirectional TVS such as the TGL41-47CA variant - which is not the TGL41-47-E3/97.
What does the "E3/97" suffix indicate in TGL41-47-E3/97?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/97" specifies packaging in 13-inch-diameter plastic tape-and-reel format containing 5000 units, optimized for high-volume SMT assembly lines requiring traceable, automated feeding of the TGL41-47-E3/97.
How does the DO-213AB (GL41) package of the TGL41-47-E3/97 compare to SMA/SMB packages in terms of thermal performance?
The DO-213AB (GL41) package of the TGL41-47-E3/97 has a 1.0 W steady-state power dissipation rating at TL = 75 °C on an infinite heatsink - identical to many SMA/SMB TVS diodes. However, its MELF geometry provides lower thermal resistance to ambient in low-airflow environments due to symmetric surface area, though PCB copper pour design remains critical for both packages to achieve rated power handling in the TGL41-47-E3/97.
Can the TGL41-47-E3/97 be used in automotive applications requiring AEC-Q200 qualification?
No - the TGL41-47-E3/97 is specified as commercial grade per Vishay's "Base P/N-E3 - RoHS compliant, commercial grade" designation and lacks AEC-Q200 stress testing validation. For automotive applications, engineers must select Vishay's AEC-Q200-qualified alternatives such as the Automotive Grade TRANSZorb® series (e.g., TGL41-47AHE3/97), not the standard TGL41-47-E3/97.
