Product details
Overview
TGL41-56A-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), 53.2–58.8 V breakdown voltage, and 77.0 V clamping voltage at 5.2 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-56A-E3/97 datasheet, TGL41-56A-E3/97 pinout, TGL41-56A-E3/97 application, or TGL41-56A-E3/97 equivalent, key selection criteria include unidirectional polarity, 47.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode uses a glass passivated planar chip junction to achieve fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction during overvoltage events while maintaining 47.8 V stand-off capability under normal operation.
The device operates within -55 °C to +150 °C junction temperature range and meets MSL level 1 per J-STD-020 with 250 °C lead-free reflow peak. Clamping occurs at 77.0 V when subjected to 5.2 A peak pulse current (10/1000 μs waveform), limiting transient energy delivered to downstream circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA56A-E3/73 | Same 56 V nominal breakdown, but SMA package (DO-214AC), 400 W rating, 5.0 μA leakage at 45.6 V VWM | Surface-mount footprint differs; requires PCB layout change due to rectangular SMA vs. cylindrical GL41 | Select when board space allows larger body and standard tape-and-reel logistics are preferred |
| SMBJ56A | DO-214AA package, 56 V VBR, 600 W PPPM, 100 μA leakage at 47.8 V VWM | Higher power rating but higher leakage; less suitable for low-power always-on circuits | Choose for higher surge immunity where leakage budget permits and thermal mass supports 600 W dissipation |
Compared with P4SMA56A-E3/73 and SMBJ56A, the TGL41-56A-E3/97 offers lower leakage (5.0 μA vs. 100 μA), MELF form factor for improved thermal cycling reliability, and tighter VBR tolerance (±5% vs. ±5% for P4SMA, ±5% for SMBJ), making it optimal for precision DC rail protection in space-constrained industrial designs.

FAQ
What is the maximum clamping voltage of the TGL41-56A-E3/97 under specified test conditions?
The TGL41-56A-E3/97 has a maximum clamping voltage (VC) of 77.0 V when subjected to a 5.2 A peak pulse current with a 10/1000 μs waveform at TA = 25 °C. This value ensures downstream components remain within safe voltage limits during transient events, and is measured per ANSI/IEEE C62.35 standards.
Is the TGL41-56A-E3/97 suitable for lead-free reflow assembly?
Yes, the TGL41-56A-E3/97 meets MSL level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 250 °C. Its matte tin-plated leads are qualified per J-STD-002 and JESD 22-B102, including Class 1A whisker testing, ensuring reliable solder joint formation in modern SMT lines.
Does the TGL41-56A-E3/97 have bidirectional polarity capability?
No, the TGL41-56A-E3/97 is unidirectional only, with polarity indicated by a blue band marking the cathode. It is designed for DC-biased applications where clamping is required in one direction only; bidirectional variants are not offered in the TGL41 family.
What is the stand-off voltage rating for the TGL41-56A-E3/97?
The TGL41-56A-E3/97 has a maximum stand-off voltage (VWM) of 47.8 V, defined as the highest DC or RMS voltage that can be continuously applied without exceeding 5.0 μA reverse leakage current. This allows safe operation in 48 V nominal systems with margin for ripple and tolerance.
How does the GL41 (DO-213AB) package of the TGL41-56A-E3/97 compare to SMA in thermal performance?
The GL41 (DO-213AB) package of the TGL41-56A-E3/97 offers superior thermal cycling reliability versus SMA due to its cylindrical MELF geometry and glass passivation, though its thermal resistance is higher than flat-pack alternatives. It delivers 400 W pulse power with validated performance up to 150 °C junction temperature, making it preferred for high-reliability industrial deployments.
