Product details
Overview
TGL41-8.2-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, with 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), and 400 W peak pulse power (10/1000 μs). It clamps transients to ≤12.1 V at 33.1 A, enabling robust protection of MOSFETs and ICs in industrial power supplies.
For engineers reviewing the TGL41-8.2-E3/97 datasheet, TGL41-8.2-E3/97 pinout, TGL41-8.2-E3/97 application, or TGL41-8.2-E3/97 equivalent, key selection criteria include unidirectional polarity, 12.1 V clamping voltage at rated surge current, DO-213AB mechanical compatibility, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) and low incremental surge resistance, ensuring effective suppression of inductive switching spikes and ESD events. Its unidirectional configuration provides forward conduction capability while maintaining precise reverse standoff behavior up to 7.02 V.
The device operates within -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 0.134 g unit weight and 13" tape-and-reel packaging (E3/97) support high-volume automated placement on PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - Ensures reliable triggering above normal operating voltage while avoiding false clamping during transients. |
| VWM | 7.02 V - Maximum continuous reverse voltage before leakage exceeds 200 μA; defines safe operating margin below VBR. |
| IPPM | 33.1 A - Peak surge current it can safely divert under 10/1000 μs waveform without degradation. |
| VC @ IPPM | ≤12.1 V - Clamped voltage seen by protected circuit during full-rated surge, limiting stress on downstream components. |
| PPPM | 400 W - Peak transient energy absorption capacity using standard 10/1000 μs test waveform at 0.01% duty cycle. |
| TJ max | 150 °C - Maximum junction temperature defining thermal derating envelope for sustained operation. |
| Package | DO-213AB (GL41) - Cylindrical plastic MELF outline with solderable matte tin-plated ends; compatible with standard pick-and-place feeders. |
Pinout & Package
DO-213AB (GL41) is a two-terminal axial plastic MELF package. The blue band denotes the cathode (positive terminal under normal TVS operation); the opposite end is the anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR. |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under repeated surge stress. |
| 400 W peak pulse power (10/1000 μs) | Supports protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) in industrial environments. |
| Low clamping ratio (VC/VBR ≈ 1.44) | Minimizes voltage overshoot across protected devices, reducing risk of latch-up or gate oxide damage in MOSFETs. |
| MSL Level 1 rating | Allows unlimited floor life and single-reflow processing at 250 °C peak without moisture-induced failure. |
| RoHS-compliant E3 suffix | Meets JESD201 Class 1A whisker resistance and UL 94 V-0 flammability for safety-critical applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA (SMB) package; 8.0 V VWM, 12.0 V VC @ 32.2 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB layout change due to different pad geometry. | Choose SMBJ8.0A only if higher surge margin is required and board space allows SMB footprint. |
| 1.5KE8.2A | DO-201AD package; 8.2 V VWM, 12.3 V VC @ 32.5 A; 1500 W PPPM; higher VF and thermal mass | Designed for chassis-level primary protection; not suitable for board-level signal line protection due to slower response. | Prefer TGL41-8.2-E3/97 for compact, fast-response board-level protection where space and speed are critical. |
Compared with SMBJ8.0A and 1.5KE8.2A, the TGL41-8.2-E3/97 offers superior fit for high-density automated assembly via its MELF form factor, tighter VBR tolerance (±5%), and lower thermal resistance in constrained layouts-making it optimal for secondary-level IC and MOSFET protection where footprint and response time are prioritized over raw power rating.

FAQ
What is the breakdown voltage range for TGL41-8.2-E3/97?
The TGL41-8.2-E3/97 has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes from -55 °C to +150 °C.
Is TGL41-8.2-E3/97 unidirectional or bidirectional?
The TGL41-8.2-E3/97 is strictly unidirectional, as confirmed in the Vishay datasheet Document Number 88403. It features a blue band marking the cathode and is intended for applications where forward conduction is acceptable-such as DC power rail protection-and does not support symmetrical AC transient suppression.
What is the maximum clamping voltage of TGL41-8.2-E3/97 under surge conditions?
The TGL41-8.2-E3/97 clamps to a maximum of 12.1 V when subjected to its rated peak pulse current of 33.1 A (10/1000 μs waveform). This value is specified in the Electrical Characteristics table and verified under standardized test conditions at TA = 25 °C.
Does TGL41-8.2-E3/97 meet RoHS and lead-free assembly requirements?
Yes, the "E3" suffix in TGL41-8.2-E3/97 indicates full RoHS compliance per Directive 2011/65/EU and qualification for lead-free reflow per J-STD-020 MSL Level 1, including a maximum peak temperature of 250 °C. Matte tin plating also satisfies JESD201 Class 1A whisker resistance testing.
What package type does TGL41-8.2-E3/97 use, and what are its key mechanical dimensions?
The TGL41-8.2-E3/97 uses the DO-213AB (GL41) plastic MELF package: cylindrical body with diameter 2.41–2.67 mm, length 5.2–6.0 mm, and solderable ends. Its compact size supports high-density placement, and the 0.134 g unit weight enables reliable feeding in automated assembly systems.
