Product details
Overview
TGL41-68-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 64.6 V to 71.4 V breakdown voltage, and 92.0 V maximum 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 TGL41-68-E3/97 datasheet, TGL41-68-E3/97 pinout, TGL41-68-E3/97 application, or TGL41-68-E3/97 equivalent, key selection criteria include unidirectional polarity, 58.1 V stand-off voltage, low 0.107 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability while clamping reverse transients above VWM = 58.1 V.
The DO-213AB (GL41) MELF package enables automated placement and meets UL 94 V-0 flammability rating. Polarity is marked by a blue cathode band; under normal operation, the cathode is positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 64.6 V / 71.4 V - ensures reliable triggering above circuit operating voltage with margin against tolerance drift |
| VWM | 58.1 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 92.0 V at 4.3 A - clamping voltage limits transient energy delivered to protected device |
| PPPM | 400 W (10/1000 μs) - handles high-energy surges common in industrial motor drives and relay coils |
| IFSM | 40 A (8.3 ms half-sine) - withstands repetitive inrush currents without degradation |
| TJ max | 150 °C - supports operation in enclosed industrial enclosures with limited airflow |
| Package | DO-213AB (GL41) - compact MELF form factor compatible with high-speed pick-and-place equipment |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is indicated by a blue band denoting the cathode (positive terminal during TVS conduction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased clamping | Connected to system ground or low-side return path; conducts during forward surge events |
| Cathode | Transient input node | Connected to protected line (e.g., DC bus); blue band identifies this terminal; carries clamped current to ground |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | DO-214AA (SMB) package; 64.0 V VBR min; 1000 W PPPM; bidirectional option available | Higher power rating but larger footprint; requires PCB layout change | Select when higher surge margin is needed and board space allows SMB footprint |
| 1.5KE68A | DO-201AD package; 64.6 V VBR min; 1500 W PPPM; axial leaded, not MELF | Through-hole mounting only; incompatible with automated SMT assembly | Select only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ64A and 1.5KE68A, the TGL41-68-E3/97 offers optimal balance of MELF manufacturability, precise 58.1 V stand-off, and 400 W capability in minimal footprint-ideal for space-constrained SMT power electronics where automated placement and thermal cycling reliability are critical.

FAQ
What is the breakdown voltage range for TGL41-68-E3/97?
The TGL41-68-E3/97 has a specified breakdown voltage (VBR) range of 64.6 V minimum to 71.4 V maximum at 1.0 mA test current. This range ensures robust margin above its 58.1 V stand-off voltage while accommodating process variation and temperature drift, making it suitable for 48 V–60 V DC systems where overvoltage tolerance must be tightly controlled.
Is TGL41-68-E3/97 unidirectional or bidirectional?
TGL41-68-E3/97 is unidirectional only, as confirmed in the Vishay datasheet. Its blue band marks the cathode, which is positive relative to the anode during normal TVS operation. It conducts in forward direction during surge events and clamps reverse transients above VWM, making it appropriate for DC rail protection where polarity is fixed.
What does the "E3/97" suffix mean in TGL41-68-E3/97?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/97" denotes packaging in 13-inch diameter plastic tape and reel with 5000 units per reel-optimized for high-volume SMT assembly lines.
What is the maximum clamping voltage of TGL41-68-E3/97 at rated peak pulse current?
The TGL41-68-E3/97 has a maximum clamping voltage (VC) of 92.0 V at its rated peak pulse current (IPPM) of 4.3 A, measured using a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is critical for ensuring downstream components remain within safe operating area.
Does TGL41-68-E3/97 meet any moisture sensitivity level (MSL) rating?
Yes, TGL41-68-E3/97 meets MSL Level 1 per J-STD-020, with a maximum lead temperature of 250 °C during reflow. This allows indefinite floor life and single-pass lead-free soldering without baking, supporting high-yield automated assembly in industrial and telecom manufacturing environments.
