Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ18A | DO-214AA (SMB) package; 10% higher VC (27.7 V); same VBR range and PPPM | Lower profile but larger footprint; less suitable for high-density MELF-optimized layouts | Select when board space allows SMB footprint and thermal mass from PCB copper pour improves sustained power handling |
| 1.5KE18A | DO-201AD (Axial) package; 1.5 kW PPPM; higher VC (29.2 V); slower response due to larger junction area | Manual assembly only; used in legacy power supply designs where axial lead spacing is fixed | Choose only for retrofit or cost-sensitive non-automated production where axial form factor is mandated |

FAQ
What is the clamping voltage of the TGL41-18-E3/96 under maximum rated surge current?
The TGL41-18-E3/96 exhibits a maximum clamping voltage (VC) of 25.2 V when subjected to its rated peak pulse current (IPPM) of 15.9 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream 30 V-rated components remain within safe operating limits during transient events. The TGL41-18-E3/96 maintains this clamping performance across its qualified temperature range.
Is the TGL41-18-E3/96 suitable for bidirectional transient protection?
No, the TGL41-18-E3/96 is strictly unidirectional, as confirmed by Vishay documentation stating "Available in uni-directional polarity only" and specifying cathode marking via blue band. For bidirectional protection, a dual-diode configuration or dedicated bidirectional TVS such as the TGL41-18CA would be required. The TGL41-18-E3/96 must be oriented with cathode toward the protected line to function correctly.
Does the TGL41-18-E3/96 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-18-E3/96 carries the E3 suffix indicating RoHS compliance per Directive 2011/65/EU and passes JESD 201 Class 1A whisker testing. Its matte tin-plated leads are solderable per J-STD-002 and rated for peak reflow temperatures up to 250 °C, making it fully compatible with lead-free reflow profiles. The TGL41-18-E3/96 is classified as commercial-grade and halogen-free per JEDEC JS709A.
What is the standoff voltage rating for the TGL41-18-E3/96, and how does it relate to circuit design?
The TGL41-18-E3/96 has a maximum working peak reverse voltage (VWM) of 15.3 V, meaning it remains non-conductive up to this DC or RMS voltage level. This allows direct use on 15 V nominal rails-such as sensor excitation supplies or gate driver bias networks-without leakage current interference. Designers must ensure operating voltage stays below 15.3 V to prevent premature conduction; the TGL41-18-E3/96 provides margin between VWM and VBR (17.1–18.9 V) for stable threshold behavior.
Can the TGL41-18-E3/96 be used in place of the TGL41-18A variant?
Yes-the TGL41-18-E3/96 is the RoHS-compliant, tape-and-reel packaged version of the TGL41-18A, sharing identical electrical characteristics, thermal ratings, and mechanical dimensions. The "E3" denotes RoHS-compliant termination and "/96" specifies 7-inch reel packaging (1500 units). No circuit or layout changes are needed when substituting TGL41-18-E3/96 for TGL41-18A in new designs or production builds.
