Product details
Overview
TGL41-22A-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), 20.9–23.1 V breakdown voltage, and 30.6 V clamping voltage at 13.1 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-22A-E3/97 datasheet, TGL41-22A-E3/97 pinout, TGL41-22A-E3/97 application, or TGL41-22A-E3/97 equivalent, key selection criteria include unidirectional polarity, 18.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
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 instantaneous forward voltage at 25 A, enabling protection of DC-biased signal lines and power rails.
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 0.095 %/°C temperature coefficient of VBR ensures stable clamping behavior under thermal variation in embedded control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V - defines reliable avalanche initiation threshold under 1.0 mA test current |
| VWM | 18.8 V - maximum continuous reverse operating voltage before significant leakage |
| VC @ IPPM | 30.6 V - clamped voltage during 13.1 A 10/1000 μs transient, limiting stress on downstream ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA22A-E3/97 | Same 22 V nominal breakdown, but SMA package (DO-214AC); 400 W rating; 33.2 V clamping at 12.0 A | Surface-mount flat package requires different pad layout; higher thermal resistance than MELF | Select when board space constraints favor rectangular footprint or existing SMA land patterns exist |
| SMAJ22A | DO-214AC package; 22 V VBR; 33.2 V VC at 12.0 A; 400 W PPPM; 1.0 W PD | Larger body height and different solder joint geometry affect automated assembly yield and thermal cycling reliability | Prefer for legacy designs already qualified with SMAJ series; verify reflow profile compatibility with matte tin finish |
Compared with TGL41-22A-E3/97, P4SMA22A-E3/97 and SMAJ22A offer identical electrical protection specs but differ in package form factor, thermal performance, and mounting compatibility-TGL41-22A-E3/97's MELF construction delivers superior power density and lower thermal resistance in constrained layouts.

FAQ
What is the clamping voltage of the TGL41-22A-E3/97 under peak pulse conditions?
The TGL41-22A-E3/97 has a maximum clamping voltage (VC) of 30.6 V at 13.1 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components remain within safe operating voltage limits during surge events. The TGL41-22A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-22A-E3/97 suitable for new designs despite the "Not For New Designs" note in Vishay documentation?
The "Not For New Designs" designation applies to the entire TGL41 family and reflects Vishay's strategic roadmap-not functional obsolescence. The TGL41-22A-E3/97 remains fully manufacturable, supported with active datasheets, and qualified for industrial and automotive applications. Aetrix Electronics confirms ongoing supply and offers lifecycle coordination for TGL41-22A-E3/97 in production programs.
What does the "/97" suffix indicate in TGL41-22A-E3/97?
The "/97" suffix in TGL41-22A-E3/97 specifies packaging: 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This differs from "/96", which denotes 7-inch reels of 1500 units. Both share identical electrical specifications, RoHS compliance (E3), and GL41 package dimensions-only the delivery format varies.
How does the TGL41-22A-E3/97 compare to bidirectional TVS diodes in circuit protection?
The TGL41-22A-E3/97 is unidirectional only, making it appropriate for DC-biased lines like power rails and gate drivers where polarity is fixed. Unlike bidirectional devices, it conducts forward current up to 40 A (IFSM) and exhibits lower forward voltage (3.5 V at 25 A), improving efficiency in clamping paths. Bidirectional alternatives require symmetric breakdown and lack this forward surge capability.
What is the thermal resistance junction-to-lead (RθJL) for the TGL41-22A-E3/97?
Vishay does not publish RθJL for the TGL41-22A-E3/97 in Document 88403. However, its GL41 (DO-213AB) MELF package achieves lower thermal resistance than flat-pack alternatives due to symmetrical geometry and direct lead contact. For thermal design, use the 1.0 W steady-state power dissipation rating at TL = 75 °C and derate linearly above that temperature per Figure 5 in the datasheet.
