Product details
Overview
TGL41-6.8-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping inductive switching transients on signal and power lines. It features 6.45 V to 7.14 V breakdown voltage (VBR), 5.80 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), 38.1 A peak pulse current (IPPM), and 10.5 V clamping voltage (VC) - used to protect MOSFETs and ICs in industrial sensor interfaces.
For engineers reviewing the TGL41-6.8-E3/97 datasheet, TGL41-6.8-E3/97 pinout, TGL41-6.8-E3/97 application, or TGL41-6.8-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility with automated placement, 1000 μA max reverse leakage at VWM, 0.060 %/°C VBR temperature coefficient, and compliance with J-STD-020 MSL Level 1.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by transient overvoltage events exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and low incremental surge resistance, enabling fast response (<1 ns) and repeatable clamping performance under repetitive 0.01 % duty cycle surges.
The device is rated for 40 A peak forward surge current (8.3 ms half-sine), supports operating junction temperatures from –55 °C to +150 °C, and maintains 1.0 W steady-state power dissipation on an infinite heatsink at 75 °C - making it suitable for high-reliability board-level ESD and lightning surge suppression where thermal derating above 25 °C must be applied per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.45 V / 7.14 V - defines precise clamping activation window; ±5 % tolerance ensures predictable turn-on across temperature and production lots |
| VWM | 5.80 V - maximum continuous reverse voltage before leakage exceeds 1000 μA; sets safe operating margin below VBR |
| IPPM | 38.1 A - peak current it safely clamps during 10/1000 μs transient; determines minimum series impedance required for system-level protection |
| VC | 10.5 V - clamped voltage at IPPM; directly limits stress on downstream ICs or MOSFETs during surge events |
| PPPM | 400 W - peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge testing |
| TJ max. | +150 °C - maximum junction temperature; enables use in enclosed industrial enclosures without active cooling |
| Package | DO-213AB (GL41) - MELF-style plastic package with matte tin-plated leads; compatible with reflow and wave soldering per J-STD-002 |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with two solderable axial terminals. 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 VLINE > VBR |
| Anode | Reference / return path | Typically tied to system ground or low-impedance return; completes clamping loop during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR and low leakage across temperature; eliminates risk of junction degradation under repeated surge stress |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow profiles up to 250 °C peak - no baking required prior to assembly |
| 400 W peak pulse power (10/1000 μs) | Validates robustness against common industrial surge waveforms including IEC 61000-4-5 and ISO 7637-2 |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients; improves clamping precision for sensitive 3.3 V or 5 V logic interfaces |
| Uni-directional polarity only | Optimized for DC-biased lines (e.g., power rails, sensor supply); avoids capacitance penalty of bi-directional designs |
Applications
| Industrial Motor Drive Protection | Automotive Sensor Interface Protection |
|---|---|
Use Scenario: Suppresses inductive kickback from 24 V solenoid drivers and relay coils in PLC I/O modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | DO-214AC (SMA) package; 6.67–7.37 V VBR; 10.0 V VC at 32.4 A; 400 W PPPM | Higher mounting profile and lower thermal mass than DO-213AB; less suitable for high-density automated placement | Choose SMAJ6.0A if board layout requires surface-mount flat package and thermal constraints allow higher junction rise |
| P6KE6.8A | DO-15 axial leaded package; 6.45–7.14 V VBR; 10.5 V VC at 38.1 A; 600 W PPPM (non-repetitive) | Larger footprint and manual assembly requirement; not RoHS-compliant in base version (E3 suffix required) | Choose P6KE6.8A only for legacy through-hole designs where DO-213AB placement equipment is unavailable |
Compared with SMAJ6.0A and P6KE6.8A, the TGL41-6.8-E3/97 offers superior automated placement compatibility via its MELF geometry, tighter VBR tolerance matching, and guaranteed RoHS/E3 compliance - critical for high-volume industrial and automotive production.

FAQ
What is the breakdown voltage range for TGL41-6.8-E3/97?
The TGL41-6.8-E3/97 has a specified breakdown voltage (VBR) range of 6.45 V to 7.14 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This ±5 % tolerance ensures consistent clamping behavior across production lots and temperature extremes from –55 °C to +150 °C, making it suitable for precision protection in regulated 5 V and 6 V systems where overvoltage margin is tight.
Is TGL41-6.8-E3/97 unidirectional or bidirectional?
TGL41-6.8-E3/97 is a unidirectional TVS diode, as confirmed by Vishay documentation stating "Available in uni-directional polarity only" and specifying cathode marking with a blue band. It is intended for DC-biased applications such as power rails and sensor supply lines, not AC signal paths - using it in bidirectional configurations would result in improper clamping or forward conduction during negative transients.
What does the "E3/97" suffix mean in TGL41-6.8-E3/97?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 22-B102 whisker resistance (Class 1A). The "/97" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units - optimized for high-speed pick-and-place assembly in volume manufacturing environments.
Can TGL41-6.8-E3/97 be used in automotive applications?
Yes, TGL41-6.8-E3/97 is qualified for automotive sensor interface protection per its 150 °C maximum junction temperature, MSL Level 1 rating, and compliance with JESD201 Class 1A whisker testing. It has been deployed in body control modules and LIN bus nodes to suppress load dump and jump-start transients, though system-level validation per AEC-Q200 is required for formal qualification.
What is the clamping voltage of TGL41-6.8-E3/97 at its rated peak pulse current?
The clamping voltage (VC) of TGL41-6.8-E3/97 is 10.5 V at its rated peak pulse current (IPPM) of 38.1 A, measured under the standardized 10/1000 μs waveform. This value represents the maximum voltage imposed on protected circuitry during worst-case surge events and is critical for ensuring downstream components like 12 V-rated MOSFETs or 5 V logic ICs remain within absolute maximum ratings.
