Product details
Overview
TGL41-68A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 64.6–71.4 V breakdown voltage, and 92.0 V clamping voltage at 4.3 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the TGL41-68A-E3/96 datasheet, TGL41-68A-E3/96 pinout, TGL41-68A-E3/96 application, or TGL41-68A-E3/96 equivalent, key selection criteria include unidirectional polarity, 58.1 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated planar chip junction to achieve fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max forward voltage at 25 A, enabling robust protection during positive-going transients while maintaining low leakage below 58.1 V.
The device operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. Its DO-213AB package supports automated placement and complies with UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V - ensures reliable triggering above 58.1 V operating voltage without false clamping |
| VWM | 58.1 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 92.0 V at 4.3 A - clamping voltage limits downstream component stress during 10/1000 μs surge |

Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable axial leads. Polarity is marked by a blue band denoting the cathode (positive terminal under normal TVS operation); the anode is the unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink | Connected to protected line; conducts surge current to ground when VBR exceeded |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage |

IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at connector entry point before signal conditioning circuitry. Use Value: Provides 58.1 V stand-off margin above 24 V system rails while adding <10 pF capacitance, minimizing signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA68A-E3/96 | Same 68 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 92 V clamping, but higher thermal resistance and lower surge current derating above 25 °C | Suitable for PCBs with surface-mount footprint constraints; less optimal for high-temperature ambient (>85 °C) due to lower power derating slope | Select P4SMA68A-E3/96 only if board layout requires flat SMD instead of axial MELF; verify thermal relief design for sustained 1.0 W dissipation |
| SMAJ68A-E3/52T | DO-214AC package, identical electrical specs (VBR: 64.6–71.4 V, VC: 92.0 V), but rated for 1.5 kW peak pulse power (10/1000 μs) and higher IPPM (6.5 A) | Better suited for systems requiring higher surge margin or multi-pulse endurance; not drop-in due to different footprint and thermal profile | Choose SMAJ68A-E3/52T when surge immunity must exceed IEC 61000-4-5 Level 4; requires PCB redesign and thermal validation |
Compared with TGL41-68A-E3/96, P4SMA68A-E3/96 offers footprint compatibility for SMT-only lines but sacrifices thermal performance, while SMAJ68A-E3/52T delivers higher surge headroom at the cost of mechanical and thermal redesign.

FAQ
What is the maximum clamping voltage of the TGL41-68A-E3/96 under specified test conditions?
The TGL41-68A-E3/96 has a maximum clamping voltage (VC) of 92.0 V when subjected to its rated peak pulse current (IPPM) of 4.3 A using a 10/1000 μs waveform at TA = 25 °C. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events.
Is the TGL41-68A-E3/96 suitable for new designs despite Vishay's "Not For New Designs" notice?
No - Vishay explicitly labels TGL41-68A-E3/96 as "Not For New Designs", recommending P4SMA68A-E3/96 as the alternative. While TGL41-68A-E3/96 remains available for legacy support and existing production, new designs should use the P4SMA series to ensure long-term supply and updated specifications.
What does the "E3/96" suffix indicate in TGL41-68A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads qualified per JESD 201 Class 1A whisker testing. The "/96" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel - standard for automated SMT placement.
How does the GL41 (DO-213AB) package of TGL41-68A-E3/96 compare thermally to SMA packages like P4SMA68A-E3/96?
The GL41 (DO-213AB) package of TGL41-68A-E3/96 provides lower thermal resistance than SMA packages due to its axial lead geometry and larger copper mass, enabling more effective heat dissipation during repetitive surges. This results in higher sustained power handling at elevated ambient temperatures compared to DO-214AC-based alternatives.
Can TGL41-68A-E3/96 be used in bidirectional configurations?
No - TGL41-68A-E3/96 is unidirectional only, as confirmed in the Vishay datasheet. Its blue band marks the cathode, and it conducts only when the cathode is positive relative to the anode. For bidirectional protection, two devices must be connected in series opposition or a dedicated bidirectional TVS (e.g., TGL41-68CA) must be selected.
