Product details
Overview
TGL41-43A-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), 40.9–45.2 V breakdown voltage, and 59.3 V clamping voltage at 6.7 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-43A-E3/97 datasheet, TGL41-43A-E3/97 pinout, TGL41-43A-E3/97 application, or TGL41-43A-E3/97 equivalent, key selection criteria include unidirectional polarity, 36.8 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 paths 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 0.104 %/°C temperature coefficient of VBR ensures stable clamping behavior over thermal variation in embedded industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V / 45.2 V - defines reliable avalanche initiation threshold under 1.0 mA test current |
| VWM | 36.8 V - maximum continuous reverse working voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 59.3 V at 6.7 A - clamped voltage during 10/1000 μs transient, limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling per 10/1000 μs waveform, 0.01% duty cycle |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), supports inrush current events |
| TJ max | +150 °C - enables operation in high-temperature industrial enclosures without derating |
| Package | GL41 (DO-213AB) - MELF-style cylindrical package with matte tin-plated leads, RoHS-compliant E3 suffix |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with axial leads. The blue band denotes the cathode terminal, which is positive relative to the anode during normal TVS operation. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Protected circuit side | Connected to line being protected; conducts avalanche current to ground when VWM exceeded |
| Anode | Reference/ground side | Typically tied to system ground or low-impedance return path; completes clamping loop during transient |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil de-energization or motor commutation without failure |
| Glass-passivated planar junction | Ensures consistent avalanche characteristics and long-term reliability under repetitive surge stress |
| MSL Level 1 moisture sensitivity | Allows direct placement into reflow assembly without baking, reducing manufacturing overhead |
| 0.104 %/°C VBR tempco | Minimizes drift in clamping threshold across operating temperature range (-55 °C to +150 °C) |
| Unidirectional polarity only | Suitable for DC-biased applications where forward conduction must be preserved during normal operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA43A-E3/97 | Same 43 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 59.3 V clamping, 6.7 A IPPM | Surface-mount flat lead vs. MELF cylindrical; requires different PCB pad layout and pick-and-place nozzle | Select for higher-volume SMT lines where DO-214AC footprint is standardized and thermal relief via copper pour is preferred |
| SMBJ43A-E3/52 | DO-214AA package; identical electrical specs (VBR 40.9–45.2 V, VC 59.3 V), but 600 W PPPM rating and 10.3 A IPPM | Higher surge margin suitable for harsher environments (e.g., railway signaling), but larger footprint and higher parasitic inductance | Choose when legacy designs require DO-214AA compatibility or when design margin demands >400 W pulse handling |
Compared with P4SMA43A-E3/97 and SMBJ43A-E3/52, the TGL41-43A-E3/97 offers optimal balance of compact MELF form factor, automated placement compatibility, and precise 400 W transient absorption-ideal for space-constrained industrial sensor modules where lead-free reflow integrity and moisture resilience are critical.

FAQ
What is the clamping voltage of the TGL41-43A-E3/97 under peak pulse conditions?
The TGL41-43A-E3/97 has a maximum clamping voltage (VC) of 59.3 V at 6.7 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see limited overvoltage during transient events. The TGL41-43A-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-43A-E3/97 suitable for new designs?
No-the Vishay datasheet explicitly states "Not For New Designs" for the TGL41-43A-E3/97, recommending the P4SMA43A-E3 series as an alternative. While the TGL41-43A-E3/97 remains available for legacy support and existing production, new designs should evaluate P4SMA43A-E3/97 or SMBJ43A-E3/52 for improved long-term supply assurance and updated qualification data.
What does the "E3/97" suffix indicate in TGL41-43A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units-optimized for high-throughput SMT assembly lines using standard MELF feeders.
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-43A-E3/97?
The GL41 (DO-213AB) MELF package provides lower thermal resistance than flat-pack alternatives due to its cylindrical geometry and axial lead configuration, enabling efficient heat dissipation along both leads. At TL = 75 °C, the TGL41-43A-E3/97 delivers 1.0 W continuous power dissipation on an infinite heatsink, supporting sustained operation in thermally dense industrial PCB layouts.
Can the TGL41-43A-E3/97 be used in bidirectional configurations?
No-the TGL41-43A-E3/97 is specified for unidirectional polarity only, with a blue band marking the cathode. It is not rated for reverse conduction and lacks symmetrical breakdown characteristics. For AC or bidirectional signal line protection, engineers must select a dedicated bidirectional TVS such as the SMBJ43CA-E3/52 or consult Vishay's bidirectional TRANSZorb® offerings.
