Product details
Overview
TGL41-82A-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), 77.9–86.1 V breakdown voltage, and 113 V clamping voltage at 3.5 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-82A-E3/97 datasheet, TGL41-82A-E3/97 pinout, TGL41-82A-E3/97 application, or TGL41-82A-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, 70.1 V stand-off voltage, low 0.108 %/°C VBR temperature coefficient, and 1.0 W steady-state power dissipation.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01 % duty cycle. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining high impedance below VWM.
Designed for surface-mount automated placement, the device meets J-STD-020 MSL Level 1 (peak reflow ≤250 °C) and JESD 201 Class 1A whisker resistance. The blue band denotes cathode polarity, with VF = 3.5 V at 25 A forward surge current.
Key Specifications

| VBR (min/max) | 77.9 V / 86.1 V - Ensures reliable triggering above 70.1 V operating voltage without false clamping |
| VWM | 70.1 V - Maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 113 V - Clamped voltage at 3.5 A peak pulse current; limits downstream stress to safe levels |
| PPPM | 400 W - Peak transient energy absorption capability per 10/1000 μs waveform |
| IFSM | 40 A - Withstands 8.3 ms half-sine surge without degradation; supports inductive load switching |
| TJ max | +150 °C - Enables operation in high-temperature industrial environments with derated power |
| Package | GL41 (DO-213AB) - Compact MELF outline optimized for high-density PCB layouts and automated assembly |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is marked by a blue band indicating the cathode (positive terminal during clamping). No internal leads or pads - terminals are the anode and cathode ends of the monolithic chip.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current sink during clamping | Connected to ground or low-impedance return path; carries full transient current to reference plane |
| Cathode (blue band end) | Current source during clamping | Connected to protected line; defines clamping threshold relative to anode potential |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against IEC 61000-4-5 Level 4 surges in industrial control inputs |
| Glass-passivated planar junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| MSL Level 1 moisture sensitivity | Enables direct placement into reflow ovens without baking; reduces manufacturing overhead |
| 0.108 %/°C VBR tempco | Maintains tight clamping window across -55 °C to +150 °C ambient operating range |
| Matte tin-plated terminals | Guarantees solderability per J-STD-002 and JESD 22-B102; prevents intermetallic voiding |
Applications
| Industrial Motor Drives | Telecom Power Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA82A-E3/97 | Same 82 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 113 V clamping, 3.5 A IPPM | SMA offers higher thermal mass and easier manual rework; less space-efficient than MELF | Select when board layout allows larger footprint and thermal relief is prioritized over density |
| SMAJ82A-E3/52 | Identical electrical specs (VBR, VC, PPPM), but DO-214AC package with different lead form and 5.2 mm tape pitch | Compatible with standard SMA pick-and-place feeders; differs in reel packaging and moisture sensitivity (MSL 1 vs MSL 1) | Choose for existing SMA-based production lines requiring drop-in replacement without feeder change |
Compared with TGL41-82A-E3/97, P4SMA82A-E3/97 offers identical clamping performance in a more thermally robust but larger package, while SMAJ82A-E3/52 delivers matching protection in a widely supported SMT format-both require PCB layout revision due to DO-214AC footprint differences.

FAQ
What is the maximum clamping voltage of the TGL41-82A-E3/97 under specified test conditions?
The TGL41-82A-E3/97 has a maximum clamping voltage (VC) of 113 V when subjected to its rated peak pulse current of 3.5 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and ensures downstream components remain within safe operating voltage limits during transient events. The TGL41-82A-E3/97 maintains this clamping performance across its full operating temperature range with minimal drift due to its 0.108 %/°C VBR coefficient.
Is the TGL41-82A-E3/97 suitable for new designs despite Vishay's "Not For New Designs" notice?
No-the "Not For New Designs" designation applies to the entire TGL41 family, including TGL41-82A-E3/97, as stated in Vishay document 88403 (Rev. 14-Nov-2023). While fully functional and available for legacy support and repair, new designs should use the recommended alternative series P4SMA6.8-E3 through P4SMA540A-E3. The TGL41-82A-E3/97 remains viable for sustaining existing production but lacks long-term roadmap commitment.
What does the "E3/97" suffix indicate in TGL41-82A-E3/97?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated terminals 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 a base quantity of 5000 units-distinct from /96 (7-inch reel, 1500 units). Both variants share identical electrical and thermal specifications for the TGL41-82A-E3/97 device.
How does the GL41 (DO-213AB) package of TGL41-82A-E3/97 compare to SMA in thermal performance?
The GL41 (DO-213AB) package used in TGL41-82A-E3/97 has lower thermal resistance than SMA due to its cylindrical geometry and direct end-terminal heat path, enabling efficient conduction to copper pads. However, its smaller surface area limits absolute power dissipation compared to SMA. At 1.0 W steady-state (PD), the TGL41-82A-E3/97 relies on PCB copper area for heatsinking, whereas SMA packages offer greater pad real estate for thermal relief-making SMA preferable for sustained high-power operation.
Can the TGL41-82A-E3/97 be used in bidirectional configurations?
No-the TGL41-82A-E3/97 is unidirectional only, as explicitly stated in the Vishay datasheet. Its internal structure supports clamping only for reverse-biased transients; forward conduction occurs above 3.5 V at 25 A, but it lacks symmetrical breakdown behavior. For bidirectional protection, a separate pair of unidirectional devices or a dedicated bidirectional TVS (e.g., P4SMA82CA-E3) must be used. Using TGL41-82A-E3/97 in reverse orientation will not provide clamping.
