Product details
Overview
TGL41-180A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, rated for 400 W peak pulse power (10/1000 μs), 171–189 V breakdown voltage, and 246 V clamping voltage at 0.81 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-180A-E3/97 datasheet, TGL41-180A-E3/97 pinout, TGL41-180A-E3/97 application, or TGL41-180A-E3/97 equivalent, key selection factors include its unidirectional polarity, 154 V stand-off voltage, low 5 μA reverse leakage at VWM, ±0.111 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated leads.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max VF at 25 A, enabling protection of DC-biased signal or power lines without interfering with normal operation.
The device operates across –55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (peak reflow ≤250 °C). Its DO-213AB package supports automated placement and delivers 1.0 W steady-state power dissipation on an infinite heatsink at 75 °C.
Key Specifications

| VBR (min/max) | 171 V / 189 V - ensures reliable triggering above system operating voltage while avoiding false clamping during transients |
| VWM | 154 V - maximum continuous reverse working voltage compatible with 150 V nominal DC bus systems |
| VC @ IPPM | 246 V - clamping voltage limits downstream component stress during 0.81 A transient events |
| PPPM | 400 W - peak pulse power rating for 10/1000 μs waveform enables robust protection against lightning-induced surges |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave supports motor drive and relay coil snubbing |
| Leakage @ VWM | 5 μA - ultra-low reverse leakage minimizes standby power loss in high-impedance sensing circuits |
| TJ Range | –55 °C to +150 °C - wide thermal range supports under-hood automotive and industrial control cabinet deployment |
Pinout & Package

IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional TGL41-180A-E3/97 placed across loop supply input to protect ADC front-end. Use Value: 246 V clamping voltage ensures downstream op-amps and references remain within absolute maximum ratings even during 1 kV/μs transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA180A-E3/73 | Same VBR (171–189 V), same DO-214AC (SMA) package, 400 W PPPM, but 1.0 W PD derated to 0.66 W at 75 °C vs. TGL41's 1.0 W at TL = 75 °C | SMA package offers PCB footprint compatibility but lacks MELF's thermal mass and automated placement robustness | Select P4SMA180A-E3/73 only if board space constraints prevent use of cylindrical MELF layout |
| SMAJ180A | Identical electrical specs (VBR, VC, PPPM) but higher 1.5 W PD rating and DO-214AC package; no MELF mechanical form factor | Higher power dissipation supports higher ambient temperatures but requires larger pad area and different pick-and-place tooling | Choose SMAJ180A when thermal margin >0.5 W is required and MELF placement infrastructure is unavailable |
Compared with P4SMA180A-E3/73 and SMAJ180A, the TGL41-180A-E3/97 delivers superior thermal stability in compact MELF form, optimized for high-reliability automated assembly and environments where mechanical robustness and consistent reflow performance are critical.

FAQ
What is the clamping voltage of the TGL41-180A-E3/97 at its rated peak pulse current?
The TGL41-180A-E3/97 has a maximum clamping voltage (VC) of 246 V at its specified peak pulse current (IPPM) of 0.81 A, measured using a 10/1000 μs waveform. This value is guaranteed per the Vishay datasheet (Document Number 88403) and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-180A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-180A-E3/97 suitable for new designs?
No-the Vishay datasheet explicitly states "Not For New Designs" for the entire TGL41-6.8A thru TGL41-200A series, including the TGL41-180A-E3/97. Vishay recommends the P4SMA6.8-E3 thru P4SMA540A-E3 series as alternatives. Engineers designing new products should evaluate those replacements for compatibility, especially regarding package (DO-214AC vs. DO-213AB), thermal derating, and long-term availability before committing to TGL41-180A-E3/97.
What does the "E3/97" suffix indicate in TGL41-180A-E3/97?
The "E3" suffix denotes 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" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units-distinct from the /96 variant (7-inch reel, 1500 units). Both variants share identical electrical and thermal specifications for the TGL41-180A-E3/97.
Does the TGL41-180A-E3/97 have bidirectional capability?
No-the TGL41-180A-E3/97 is unidirectional only, as confirmed in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It functions as a reverse-biased avalanche diode for transient suppression on positively referenced lines. For AC or bipolar signal protection, a separate bidirectional TVS (e.g., P4SMA180CA) would be required. The blue band on the TGL41-180A-E3/97 marks the cathode, which must be connected to the line being protected.
What is the maximum junction temperature rating for the TGL41-180A-E3/97?
The TGL41-180A-E3/97 has a maximum junction temperature (TJ) rating of +150 °C, with an operating junction and storage temperature range of –55 °C to +150 °C. This rating is validated per JEDEC standards and supports deployment in high-temperature industrial enclosures and under-hood automotive locations. Derating curves in the datasheet (Fig. 2 and Fig. 5) define allowable power reduction above 25 °C ambient to maintain TJ ≤ 150 °C for the TGL41-180A-E3/97.
