Product details
Overview
TGL41-39A-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), 37.1–41.0 V breakdown voltage (VBR), and 53.9 V clamping voltage (VC) at 7.4 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial sensor signal lines.
For engineers reviewing the TGL41-39A-E3/97 datasheet, TGL41-39A-E3/97 pinout, TGL41-39A-E3/97 application, or TGL41-39A-E3/97 equivalent, key selection criteria include unidirectional polarity, 33.3 V stand-off voltage (VWM), 5.0 μA max reverse leakage, 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 (<1 ns) and low incremental surge resistance, enabling effective clamping of transient energy before sensitive downstream components are stressed. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining high impedance under normal bias.
The device operates within -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 with 250 °C lead-free reflow peak. Its 1.0 W steady-state power dissipation and 40 A 8.3 ms surge rating support robust protection in intermittent fault conditions without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - Ensures reliable triggering above 33.3 V operating voltage while avoiding false trips during normal transients. |
| VWM | 33.3 V - Maximum continuous reverse working voltage; defines upper limit of safe DC or AC signal swing before conduction begins. |
| VC @ IPPM | 53.9 V at 7.4 A - Clamped voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream ICs. |
| PPPM | 400 W - Peak pulse power handling capability with standard 10/1000 μs waveform; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| IFSM | 40 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports single-event inductive kick survival without bond wire failure. |
| Junction Temp | -55 °C to +150 °C - Enables deployment in under-hood automotive, industrial motor drives, and outdoor telecom equipment. |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal during clamping). No discrete pins-two axial terminals with symmetric geometry optimized for tape-and-reel automated placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference node for reverse-biased operation | Connected to ground or low-impedance return path; establishes reference for clamping threshold relative to protected line. |
| Cathode (blue banded end) | Transient current sink during overvoltage | Connected to protected signal/power line; conducts surge current to ground when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Validates compliance with IEC 61000-4-5 surge immunity requirements for industrial control interfaces. |
| Glass-passivated planar junction | Delivers sub-nanosecond response and stable VBR over lifetime, critical for protecting high-speed sensor outputs. |
| MSL Level 1 (250 °C peak) | Enables single-pass lead-free reflow assembly without moisture-induced cracking or delamination. |
| Unidirectional polarity only | Simplifies layout in DC-biased rails (e.g., 24 V PLC inputs) where reverse conduction is not required. |
| UL 94 V-0 molding compound | Meets flammability safety standards for enclosed industrial enclosures and telecom base stations. |
Applications
| Industrial Sensor Signal Protection | PLC Digital Input Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA39A-E3 | Same 39 V nominal breakdown, but SMA package (DO-214AC) instead of DO-213AB; 400 W rating, 53.3 V clamping at 7.5 A. | SMA offers higher board-level mechanical robustness and easier manual rework; less suited for ultra-high-density automated placement than MELF. | Select P4SMA39A-E3 when PCB layout allows larger footprint and serviceability is prioritized over placement density. |
| SMAJ39A | Identical electrical specs (39 V VBR, 53.3 V VC), but legacy non-RoHS-compliant version; same DO-214AC package as P4SMA39A-E3. | Lacks JESD201 Class 1A whisker resistance and RoHS compliance; unsuitable for new commercial designs targeting EU/China markets. | Choose SMAJ39A only for legacy repair or non-regulated environments where RoHS and whisker resistance are not mandated. |
Compared with TGL41-39A-E3/97, P4SMA39A-E3 offers identical clamping performance in a more serviceable package but sacrifices MELF's placement density and thermal profile; SMAJ39A matches performance but lacks modern reliability certifications required for new production.

FAQ
What is the clamping voltage of the TGL41-39A-E3/97 under a 10/1000 μs surge?
The TGL41-39A-E3/97 has a maximum clamping voltage (VC) of 53.9 V at 7.4 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits experience no more than 53.9 V during transient events, directly supporting design margins for 3.3 V, 5 V, and 24 V logic interfaces. The TGL41-39A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-39A-E3/97 suitable for bidirectional signal line protection?
No, the TGL41-39A-E3/97 is unidirectional only, with a blue band marking the cathode terminal. It conducts surge current only when the cathode is positive relative to the anode, making it appropriate for DC-biased lines like 24 V PLC inputs or sensor power feeds-but not for AC or fully differential signals requiring symmetrical clamping. For bidirectional protection, designers must select a dedicated bidirectional TVS such as the SMBJ39CA. The TGL41-39A-E3/97 datasheet explicitly states "Available in unidirectional polarity only."
What does the "/97" suffix indicate in TGL41-39A-E3/97?
Per Vishay's ordering information, the "/97" suffix in TGL41-39A-E3/97 specifies a 13-inch diameter plastic tape-and-reel packaging format containing 5000 units per reel. This contrasts with "/96", which denotes a 7-inch reel with 1500 units. Both share identical electrical and thermal specifications; the suffix solely identifies packaging configuration for automated SMT placement equipment compatibility. The TGL41-39A-E3/97 is RoHS-compliant and meets JESD201 Class 1A whisker resistance.
How does the TGL41-39A-E3/97 compare to older SMAJ-series TVS diodes?
The TGL41-39A-E3/97 delivers identical 39 V breakdown and 53.9 V clamping performance as SMAJ39A but in a smaller DO-213AB (GL41) MELF package with superior thermal mass per unit volume and tighter VBR tolerance (±5% vs ±10%). Unlike SMAJ39A, the TGL41-39A-E3/97 is RoHS-compliant, MSL Level 1 qualified, and features matte tin plating compliant with J-STD-002. The TGL41-39A-E3/97 replaces legacy parts where high-density placement and modern process compliance are required.
Why is the TGL41-39A-E3/97 marked "Not For New Designs"?
Vishay designates the TGL41-39A-E3/97 as "Not For New Designs" because it has been superseded by the P4SMA39A-E3 series, which offers identical electrical performance in the more widely supported SMA (DO-214AC) package with enhanced manufacturability and broader distributor availability. The TGL41-39A-E3/97 remains available for existing designs and legacy production, but new projects should evaluate P4SMA39A-E3 for long-term supply assurance. This status appears in the official Vishay document 88403 revision 14-Nov-2023.
