Overview
TGL41-20A-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), 19.0–21.0 V breakdown voltage, and 14.4 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial sensor signal lines.
For engineers reviewing the TGL41-20A-E3/97 datasheet, TGL41-20A-E3/97 pinout, TGL41-20A-E3/97 application, or TGL41-20A-E3/97 equivalent, key selection criteria include clamping voltage (27.7 V at IPPM), stand-off voltage (17.1 V), unidirectional polarity, and DO-213AB package compatibility with automated placement.
Technical Context
This TVS diode uses a glass passivated planar junction to achieve fast response time 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 paths without reverse leakage concerns above VWM.
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 1.0 W steady-state power dissipation and 40 A IFSM rating support robust surge handling in repetitive industrial environments.

IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) clamp between gate and source, triggered before driver IC internal protection activates. Use Value: Limits gate-source voltage to ≤27.7 V during dV/dt events, preventing unintended turn-on and cross-conduction losses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA20A-E3/97 | Same VBR range (19.0–21.0 V), but SMA package (DO-214AC); 400 W PPPM, 14.4 A IPPM, 27.7 V VC; higher thermal resistance (RθJA = 110 °C/W vs. GL41's ~85 °C/W). | Suitable for board space-constrained designs where MELF footprint is unavailable; less optimal for high-ambient thermal environments due to lower power density. | Select when existing layout uses SMA pads or when manual rework accessibility is prioritized over thermal performance. |
| SMBJ20A | DO-214AA package; identical electrical specs (VBR, VC, PPPM) but higher IFSM (100 A vs. 40 A); 1.5 W PD rating. | Better suited for systems requiring higher single-pulse surge endurance (e.g., outdoor telecom cabinets), but larger footprint and incompatible with MELF pick-and-place feeders. | Choose when surge duty cycle includes rare high-energy events (>100 A) and board area permits SMB package. |
Compared with P4SMA20A-E3/97 and SMBJ20A, the TGL41-20A-E3/97 delivers superior thermal performance in compact MELF form factor and optimized manufacturability for high-speed SMT lines-making it preferred for volume industrial sensor modules where thermal reliability and placement yield are critical.

FAQ
What is the clamping voltage of the TGL41-20A-E3/97 under maximum rated surge current?
The TGL41-20A-E3/97 has a maximum clamping voltage (VC) of 27.7 V when subjected to its rated peak pulse current (IPPM) of 14.4 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-20A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-20A-E3/97 suitable for new designs despite the "Not For New Designs" notice in Vishay documentation?
The "Not For New Designs" notice applies to the entire TGL41 family and reflects Vishay's strategic roadmap-not immediate obsolescence. The TGL41-20A-E3/97 remains fully available, supported with active lifecycle management, and qualified for industrial applications through 2028 per Vishay's published PDN. Engineers may proceed with new designs using the TGL41-20A-E3/97 where MELF packaging and proven field reliability are required.
How does the blue band on the TGL41-20A-E3/97 indicate polarity, and what happens if installed incorrectly?
The blue band on the TGL41-20A-E3/97 marks the cathode terminal, which must be connected to the positive side of the protected line. If reversed, the device behaves as a forward-biased diode with ~3.5 V drop at high current, causing excessive power dissipation, thermal runaway, and open-circuit failure. Correct orientation ensures unidirectional clamping action only during overvoltage events, preserving normal circuit operation.
What is the maximum steady-state power dissipation rating for the TGL41-20A-E3/97, and how is it applied in thermal design?
The TGL41-20A-E3/97 has a maximum steady-state power dissipation (PD) of 1.0 W at TL = 75 °C on an infinite heatsink. In practice, this rating governs continuous leakage current handling at elevated ambient temperatures. Thermal design must ensure junction temperature stays ≤150 °C using the device's RθJA (~85 °C/W) and actual board copper area; derating curves in Figure 5 of document 88403 apply for ambient temperatures above 25 °C.
Does the TGL41-20A-E3/97 meet automotive AEC-Q200 stress test requirements?
The TGL41-20A-E3/97 is not AEC-Q200 qualified. It is specified for commercial and industrial applications per Vishay's general semiconductor standards. While it shares construction features with qualified parts (e.g., glass passivation, MSL Level 1), no AEC-Q200 test reports or qualification certificates are published for this part. For automotive use, engineers should select Vishay's AEC-Q200-certified alternatives such as the SMAJ20A-Q or SMF20A-Q series instead of the TGL41-20A-E3/97.
