Product details
Overview
TGL41-68A-E3/97 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 and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-68A-E3/97 datasheet, TGL41-68A-E3/97 pinout, TGL41-68A-E3/97 application, or TGL41-68A-E3/97 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 DO-213AB mechanical compatibility with automated placement systems.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability up to 40 A IFSM while clamping reverse transients to ≤92.0 V at 4.3 A IPPM.
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 enables high-density PCB layout and supports 0.01% duty cycle repetitive surge handling.

Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable axial terminals. The blue band denotes the cathode (positive terminal under normal TVS operation); anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient clamp output node | Connected to protected line; sinks surge current to ground when VREV > VBR |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges without derating at 25 °C |
| Glass-passivated planar junction | Delivers stable VBR tolerance (±5%) and low leakage (<5 μA) over lifetime and temperature |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard Pb-free reflow without baking preconditioning |
| Unidirectional polarity only | Simplifies circuit design for DC-biased lines where forward conduction must be preserved |
| Matte tin-plated leads | Ensures reliable solderability per J-STD-002 and JESD 22-B102, including whisker resistance (JESD 201 Class 1A) |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and PWM controllers from flyback voltage spikes generated by relay coils and solenoid loads. IC Role / Device Role / Timing Role: Transient voltage suppressor placed across DC bus or control signal lines to clamp spikes below MOSFET VDSS rating.

IC Role / Device Role / Timing Role: Primary-level TVS connected between line and neutral or line-to-ground to absorb 400 W transients per IEC 61000-4-5. Use Value: Maintains system uptime by limiting voltage excursions to <92.0 V, preserving downstream regulator and controller IC integrity. |
| Automotive Body Control Modules | Consumer Appliance Power Boards |

IC Role / Device Role / Timing Role: Localized TVS on signal lines (e.g., water level sensor, door lock actuator) to limit ESD and inductive kickback. Use Value: Reduces field returns by eliminating false resets and analog sensor offset drift induced by sub-100 ns transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA68A-E3 | DO-41 package (axial leaded), 600 W PPPM, 64.6–71.4 V VBR, 110 V VC @ 3.6 A | Requires through-hole mounting; higher clamping voltage reduces margin for 5 V logic protection | Select when legacy through-hole assembly is required and board space allows larger footprint |
| SMAJ68A | SMA package (flat lead), 400 W PPPM, 64.6–71.4 V VBR, 110 V VC @ 3.6 A, 150 °C TJ | Surface-mount but larger body than DO-213AB; same thermal limits but lower surge current density | Choose for reflow-compatible SMT process where MELF placement equipment is unavailable |
Compared with P4SMA68A-E3 and SMAJ68A, the TGL41-68A-E3/97 offers tighter clamping (92.0 V vs. 110 V), superior surge current density in a smaller DO-213AB outline, and MELF-specific advantages in high-frequency transient response and automated placement yield.

FAQ
What is the clamping voltage of the TGL41-68A-E3/97 under standard test conditions?
The TGL41-68A-E3/97 has a maximum clamping voltage (VC) of 92.0 V at 4.3 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The TGL41-68A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-68A-E3/97 suitable for new designs despite the "Not For New Designs" notice?
The "Not For New Designs" designation applies to the entire TGL41 family and indicates Vishay recommends newer alternatives like the P4SMA series for future projects. However, the TGL41-68A-E3/97 remains fully supported, in active production, and appropriate for sustaining existing designs, replacement programs, or applications requiring its specific DO-213AB form factor and clamping performance. The TGL41-68A-E3/97 continues to meet all published specifications.
What does the "E3/97" suffix mean in TGL41-68A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units per reel. This format is optimized for high-speed pick-and-place assembly. The TGL41-68A-E3/97 is distinct from the /96 variant (7-inch reel, 1500 units).
How does the TGL41-68A-E3/97 compare to bidirectional TVS diodes in surge protection?
The TGL41-68A-E3/97 is unidirectional only, meaning it conducts in forward bias like a rectifier and clamps only in reverse. This makes it ideal for DC lines with defined polarity, offering lower leakage and tighter VC than equivalent bidirectional parts. Bidirectional variants would require symmetric breakdown in both directions and typically exhibit higher VC and leakage. The TGL41-68A-E3/97 is not interchangeable with bidirectional TVS devices without circuit redesign.
What is the maximum operating temperature for the TGL41-68A-E3/97 junction?
The TGL41-68A-E3/97 has a maximum junction temperature (TJ) rating of +150 °C, with a storage temperature range from -55 °C to +150 °C. Derating of peak pulse power begins above 25 °C ambient per Figure 2 in the datasheet, and the device maintains full specification compliance within this thermal envelope. Thermal design must ensure sustained power dissipation (PD = 1.0 W) does not exceed limits at elevated board temperatures. The TGL41-68A-E3/97 is qualified for under-hood automotive and industrial environments.
