Product details
Overview
TGL41-91A-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), 86.5–95.5 V breakdown voltage, and 125 V clamping voltage at 3.2 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-91A-E3/97 datasheet, TGL41-91A-E3/97 pinout, TGL41-91A-E3/97 application, or TGL41-91A-E3/97 equivalent, key selection criteria include unidirectional polarity, 77.8 V stand-off voltage, 5 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 junction to achieve fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining high impedance under normal operation up to 77.8 V.
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. Its DO-213AB package enables automated placement and complies with UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 86.5 V / 95.5 V - ensures reliable triggering above system operating voltage with ±5% tolerance |
| VWM | 77.8 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 125 V - clamping voltage limits downstream IC stress during 3.2 A transient events |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform at 0.01% duty cycle |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave, supporting robust inrush protection |
| Junction temp | -55 °C to +150 °C - supports operation in harsh industrial and automotive under-hood environments |
| Package | GL41 (DO-213AB) - compact MELF form factor optimized for high-density PCB layouts and automated assembly |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable axial leads. Polarity is marked by a blue band denoting the cathode (positive terminal during TVS operation); anode is the unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | TVS output node | Connected to protected line; conducts when transient exceeds VBR, shunting current to ground |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable VBR tolerance and long-term reliability under repeated surge stress |
| 400 W peak pulse power | Supports protection of 24 V and 48 V industrial bus lines against IEC 61000-4-5 level 4 surges |
| Low clamping ratio (VC/VBR ≈ 1.31) | Minimizes overvoltage exposure to downstream logic or analog circuitry during clamping |
| MSL Level 1 rating | Allows direct placement into lead-free reflow without baking, reducing manufacturing overhead |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker test, ensuring solder joint integrity in vibration-prone applications |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA91A-E3/97 | Same VBR (86.5–95.5 V), same DO-214AC (SMA) package, but lower PPPM = 400 W (same rating), higher VC = 139 V | Higher clamping voltage increases risk to downstream 3.3 V logic; better suited for 12 V+ systems with margin | Select when board layout requires surface-mount SMA footprint instead of MELF, accepting 14 V higher clamping. |
| SMBJ90A | DO-214AA (SMB) package, VBR = 100–111 V, VC = 146 V, PPPM = 600 W, IPPM = 4.1 A | Higher power rating suits higher-energy transients; wider VBR range may require redesign of overvoltage detection thresholds | Choose for enhanced surge margin in 48 V telecom systems where PCB space allows SMB footprint and clamping voltage is acceptable. |
Compared with P4SMA91A-E3/97 and SMBJ90A, the TGL41-91A-E3/97 offers superior clamping performance (125 V vs. ≥139 V) in a compact MELF package ideal for high-density automated assembly, though it is marked "Not For New Designs" per Vishay's revision notice.

FAQ
What is the clamping voltage of the TGL41-91A-E3/97 under peak pulse conditions?
The TGL41-91A-E3/97 has a maximum clamping voltage (VC) of 125 V at 3.2 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures predictable overvoltage limiting for downstream circuitry. The TGL41-91A-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-91A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-91A-E3/97 as "Not For New Designs" in its official documentation (Rev. 14-Nov-2023, Doc. #88403). Engineers developing new products should consider approved alternatives like the P4SMA91A-E3/97 or SMBJ90A. The TGL41-91A-E3/97 remains supported for existing production and legacy BOM continuity.
What does the "E3/97" suffix indicate in TGL41-91A-E3/97?
The "E3" suffix denotes RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 1A whisker testing. The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This format supports high-volume automated pick-and-place assembly.
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-91A-E3/97?
The GL41 (DO-213AB) MELF package provides moderate thermal resistance due to its small cylindrical geometry and axial lead configuration. The TGL41-91A-E3/97 is rated for 1.0 W power dissipation on an infinite heatsink at 75 °C lead temperature (TL). Board-level thermal design must ensure adequate copper area and via stitching to maintain junction temperature ≤150 °C under sustained surge conditions.
What is the reverse leakage current specification for the TGL41-91A-E3/97 at its working voltage?
At the maximum stand-off voltage (VWM) of 77.8 V and ambient temperature of 25 °C, the TGL41-91A-E3/97 exhibits a maximum reverse leakage current (ID) of 5.0 μA. This low leakage preserves power budget in always-on sensor interfaces and battery-backed systems, and remains stable across the full -55 °C to +150 °C operating junction temperature range.
