Product details
Overview
TGL41-6.8A-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), 6.45–7.14 V breakdown voltage, and 10.5 V clamping voltage at 38.1 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial sensor signal lines.
For engineers reviewing the TGL41-6.8A-E3/97 datasheet, TGL41-6.8A-E3/97 pinout, TGL41-6.8A-E3/97 application, or TGL41-6.8A-E3/97 equivalent, key selection criteria include unidirectional polarity, 5.8 V stand-off voltage, 1000 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
Technical Context
The TGL41-6.8A-E3/97 uses a glass-passivated planar junction to achieve fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction only during overvoltage events, with cathode marked by a blue band and clamping action triggered above 6.45 V breakdown threshold.
Designed for transient suppression per ANSI/IEEE C62.35, it delivers 400 W peak pulse power at TA = 25 °C but derates to 200 W above 91 V and follows J-STD-020 MSL Level 1 moisture sensitivity with 250 °C lead-free reflow peak temperature capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 6.45 V to 7.14 V - defines precise voltage threshold at which avalanche conduction begins under 10 mA test current |
| VWM | 5.8 V - maximum continuous reverse operating voltage before significant leakage occurs |
| IPPM | 38.1 A - peak pulse current supported with 10/1000 μs waveform before clamping exceeds 10.5 V |
| VC | 10.5 V - clamped voltage across device during IPPM, limiting stress on downstream circuitry |
| PPPM | 400 W - transient energy absorption capacity under standardized surge conditions |
| TJ max | +150 °C - maximum allowable junction temperature for reliable long-term operation |
| IR @ VWM | 1000 μA - reverse leakage current at stand-off voltage, critical for low-power sensor line integrity |
Pinout & Package
Package: GL41 (DO-213AB) - cylindrical plastic MELF case with matte tin-plated leads, 0.105" diameter × 0.238" length, MSL Level 1, RoHS-compliant (E3 suffix), JESD201 Class 1A whisker tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference terminal for reverse-biased operation | Connected to system ground or lower-potential node; conducts during transient when cathode voltage exceeds anode by ≥VBR |
| Cathode | Protected line connection point | Marked with blue band; connects to signal/power line requiring protection; sinks surge current to anode during clamping |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF package | Enables high-density automated placement and consistent thermal performance in compact layouts |
| Glass passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Handles common industrial lightning and inductive switch-off transients without degradation |
| Low clamping ratio (VC/VBR ≈ 1.55) | Minimizes overvoltage exposure to protected ICs while maintaining fast response |
| Unidirectional polarity only | Simplifies design for DC-biased lines where reverse conduction is not required |
Applications
| Industrial Sensor Signal Protection | DC Motor Drive Gate Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in factory automation PLC modules exposed to relay coil flyback. IC Role / Device Role / Timing Role: TVS diode placed between sensor output and microcontroller ADC input to clamp transients before they reach ESD-sensitive front-end circuitry. Use Value: Limits induced voltage spikes to ≤10.5 V, preserving signal integrity and preventing ADC saturation or latch-up in 3.3 V or 5 V systems. | Use Scenario: Shielding N-channel MOSFET gate drivers in 24 V DC motor H-bridge controllers from cross-talk and supply rail bounce. IC Role / Device Role / Timing Role: Mounted directly across gate-source terminals to suppress sub-100 ns ringing and prevent false turn-on during high dv/dt switching. Use Value: Fast response (<1 ps) and low dynamic impedance ensure gate voltage stays within ±0.5 V of intended level during commutation events. |
| Telecom Line Interface Protection | Consumer Appliance Power Supply Input |
Use Scenario: Safeguarding RS-485 transceiver inputs in building management systems connected to long cable runs susceptible to EFT and lightning-induced surges. IC Role / Device Role / Timing Role: Installed on differential bus lines (A/B) with common-mode choke to absorb common-mode transients before reaching transceiver ESD structures. Use Value: 400 W rating and 10.5 V clamping enable compliance with IEC 61000-4-4 Level 4 (4 kV) without additional series impedance. | Use Scenario: Suppressing inrush and switching transients on the primary-side rectifier output of switch-mode power supplies in smart home hubs. IC Role / Device Role / Timing Role: Placed across bulk capacitor input to clamp voltage overshoot during cold-start or load dump events. Use Value: Withstands 40 A non-repetitive forward surge (IFSM) and maintains 1.0 W steady-state dissipation without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA6.8-E3 | Same 6.8 V nominal breakdown, but SMA package (DO-214AC); 400 W rating; higher capacitance (~50 pF vs. ~15 pF) | Less suitable for high-frequency signal lines due to higher junction capacitance; better for PCB space-constrained layouts with SMT reflow | Select P4SMA6.8-E3 when board real estate limits MELF placement or when legacy SMA footprint reuse is required |
| SMAJ6.8A | DO-214AC package; 600 W peak power; tighter VBR tolerance (6.45–7.14 V same); 10.5 V clamping identical | Higher surge margin supports more severe environments (e.g., automotive load dump), but larger footprint and higher cost | Choose SMAJ6.8A only if 600 W rating is mandated by system-level surge testing requirements |
Compared with TGL41-6.8A-E3/97, P4SMA6.8-E3 offers footprint flexibility at the cost of higher parasitic capacitance, while SMAJ6.8A increases surge headroom but requires layout revision-neither is pin-compatible due to differing DO-213AB vs. DO-214AC packages.

FAQ
What is the exact breakdown voltage range for TGL41-6.8A-E3/97?
The TGL41-6.8A-E3/97 has a guaranteed breakdown voltage range of 6.45 V to 7.14 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This tight VBR window ensures predictable clamping onset across production lots and temperature extremes, making TGL41-6.8A-E3/97 suitable for precision protection where overvoltage margin must be tightly controlled.
Is TGL41-6.8A-E3/97 suitable for bidirectional transient suppression?
No, TGL41-6.8A-E3/97 is unidirectional only, with cathode marked by a blue band and designed for DC-biased lines. It does not suppress positive transients on the anode side. For bidirectional protection, a separate device such as the SMBJ6.8CA or dual-diode array would be required-TGL41-6.8A-E3/97 must be used in polarity-aware orientation per its datasheet specification.
What is the maximum clamping voltage of TGL41-6.8A-E3/97 under surge conditions?
The TGL41-6.8A-E3/97 clamps to a maximum of 10.5 V at its rated peak pulse current of 38.1 A (10/1000 μs waveform). This value is verified per Fig. 5 in Vishay document 88403 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events, ensuring compatibility with 3.3 V, 5 V, and 12 V logic interfaces.
Does TGL41-6.8A-E3/97 meet lead-free soldering requirements?
Yes, TGL41-6.8A-E3/97 carries the E3 suffix indicating full compliance with JESD201 Class 1A whisker testing and RoHS Directive 2011/65/EU. Its matte tin-plated leads are qualified for lead-free reflow up to 250 °C peak temperature (MSL Level 1), supporting standard Pb-free assembly processes without post-solder annealing.
Why is TGL41-6.8A-E3/97 marked as "Not For New Designs"?
Vishay designates TGL41-6.8A-E3/97 as "Not For New Designs" because newer platforms like the P4SMA and SMAJ families offer improved surge ratings, tighter tolerances, or enhanced package options. However, TGL41-6.8A-E3/97 remains fully manufactured and supported for existing designs, with no announced discontinuance date and full technical documentation available via Vishay document 88403.
