Product details
Overview
TGL41-8.2A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, designed for clamping voltage transients on signal and power lines. It features 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 12.1 V clamping voltage at 33.1 A peak pulse current (IPPM), and 400 W peak pulse power capability with 10/1000 µs waveform - used in sensor interface protection and MOSFET gate drive circuits.
For engineers reviewing the TGL41-8.2A-E3/97 datasheet, TGL41-8.2A-E3/97 pinout, TGL41-8.2A-E3/97 application, or TGL41-8.2A-E3/97 equivalent, key selection considerations include unidirectional polarity, DO-213AB mechanical compatibility, 12.1 V clamping performance at 33.1 A, thermal derating above 25 °C, and RoHS-compliant matte tin-plated terminals meeting J-STD-002 solderability.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR (7.79–8.61 V). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<200 µA at VWM), while the MELF package enables automated placement and meets UL 94 V-0 flammability rating.
The device delivers 400 W peak pulse power (10/1000 µs) up to 25 °C, derating linearly above that temperature per Fig. 2, and supports 40 A non-repetitive forward surge current (8.3 ms half-sine). Its 0.068 %/°C VBR temperature coefficient ensures predictable voltage shift across -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - defines minimum and maximum voltage at which avalanche conduction begins under 10 mA test current |
| VWM | 7.02 V - maximum continuous reverse working voltage before significant leakage occurs |
| VC @ IPPM | 12.1 V at 33.1 A - clamped voltage seen by protected circuit during 10/1000 µs transient |
| PPPM | 400 W - peak pulse power handling capacity under standard 10/1000 µs waveform, 0.01% duty cycle |
| IFSM | 40 A - maximum non-repetitive forward surge current (8.3 ms half-sine), critical for inductive switch-off events |
| TJ Range | -55 °C to +150 °C - junction temperature limits defining operational and storage envelope |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with blue cathode band, 0.105" diameter, lead-free matte tin terminations |
Pinout & Package
GL41 (DO-213AB) is a two-terminal axial plastic MELF package. The blue band denotes the cathode (positive terminal under normal TVS operation); the anode is the unmarked end. Terminals are matte tin plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient clamp output node | Connected to protected line; conducts avalanche current to ground/anode during overvoltage event |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping current path |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF packaging | Enables high-speed automated placement and eliminates leadframe-related parasitics for fast response |
| Glass-passivated junction | Ensures stable VBR tolerance and low leakage (<200 µA at VWM) over lifetime and temperature |
| 400 W peak pulse power (10/1000 µs) | Provides robust protection against common ESD and inductive switching transients in consumer and industrial systems |
| MSL Level 1 compliance | Allows unlimited floor life and reflow up to 250 °C peak, simplifying SMT assembly without baking |
| Unidirectional polarity only | Optimized for DC-biased lines where reverse conduction must be blocked except during clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA8.2-E3/97 | Same VBR (7.79–8.61 V), same DO-214AC (SMA) package footprint but different outline; 400 W PPPM, higher VC = 13.4 V at 29.9 A | SMA package offers PCB area savings vs. MELF but lower thermal mass; less suitable for high-reliability automated optical inspection | Select P4SMA8.2-E3/97 if board space is constrained and SMA mounting is preferred over MELF placement. |
| SMBJ8.0A | Higher VWM = 8.0 V, VC = 12.0 V at 32.4 A, same 400 W rating; SMB package (DO-214AA) with 2.5 mm body width vs. GL41's 2.67 mm diameter | SMB offers better thermal dissipation than MELF but requires larger pad layout; not compatible with MELF pick-and-place nozzles | Choose SMBJ8.0A when higher thermal margin is needed and board layout allows wider footprint. |
Compared with TGL41-8.2A-E3/97, P4SMA8.2-E3/97 trades MELF placement reliability for smaller footprint, while SMBJ8.0A provides superior thermal performance at the cost of mechanical incompatibility with GL41 tooling - all three maintain comparable clamping voltage and surge current capability for 8 V-class DC line protection.

FAQ
What is the breakdown voltage range of the TGL41-8.2A-E3/97?
The TGL41-8.2A-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 range reflects manufacturing tolerance and ensures reliable avalanche initiation across temperature and unit variance. The value is confirmed in the Electrical Characteristics table of Vishay document 88403, revision 14-Nov-2023.
Is the TGL41-8.2A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-8.2A-E3/97 as "Not For New Designs" in document 88403, recommending P4SMA6.8-E3 through P4SMA540A-E3 as alternatives. While fully functional and supported for existing production, new projects should evaluate the P4SMA series for long-term availability and updated qualification. The TGL41-8.2A-E3/97 remains available for legacy program continuity.
What does the /97 suffix indicate in TGL41-8.2A-E3/97?
The /97 suffix in TGL41-8.2A-E3/97 specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This differs from /96 (7-inch reel, 1500 units). Both share identical electrical and mechanical specifications; the suffix solely identifies reel size and quantity - critical for SMT line setup and inventory planning for the TGL41-8.2A-E3/97.
How does the clamping voltage of TGL41-8.2A-E3/97 compare to its stand-off voltage?
The TGL41-8.2A-E3/97 has a stand-off voltage (VWM) of 7.02 V and a maximum clamping voltage (VC) of 12.1 V at 33.1 A peak pulse current. This 5.08 V differential ensures safe margin between normal operation and clamping onset, preventing false triggering while delivering effective protection. The ratio VC/VWM ≈ 1.72 is typical for unidirectional TVS diodes in this power class.
Does the TGL41-8.2A-E3/97 have bidirectional capability?
No - the TGL41-8.2A-E3/97 is unidirectional only, as stated in the FEATURES section of document 88403. It conducts avalanche current only when the cathode is positive relative to the anode. For bidirectional protection, a separate device such as the TGL41-8.2CA or alternative dual-diode configurations would be required. Polarity is marked by a blue band denoting the cathode on the TGL41-8.2A-E3/97.
