Product details
Overview
TGL41-15A-E3/96 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), 14.3–15.8 V breakdown voltage, and 21.2 V clamping voltage at 18.9 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-15A-E3/96 datasheet, TGL41-15A-E3/96 pinout, TGL41-15A-E3/96 application, or TGL41-15A-E3/96 equivalent, key selection criteria include unidirectional polarity, 12.8 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 (<1 ns), low incremental surge resistance, and stable clamping under repetitive 10/1000 μs transients at 0.01% duty cycle. Its unidirectional configuration provides forward conduction capability up to 40 A IFSM (8.3 ms half-sine).
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 blue band denotes cathode polarity, and it complies with UL 94 V-0 flammability rating for the molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 14.3–15.8 V at 1.0 mA test current - defines minimum voltage at which clamping initiates reliably |
| Stand-off Voltage VWM | 12.8 V - maximum continuous reverse working voltage before leakage exceeds 5.0 μA |
| Clamping Voltage VC | 21.2 V at 18.9 A IPPM - peak voltage seen by protected circuit during 10/1000 μs transient |
| Peak Pulse Power PPPM | 400 W (10/1000 μs) - energy-handling capacity for single non-repetitive surges |
| Peak Pulse Current IPPM | 18.9 A - maximum surge current the device safely clamps without failure |
| Junction Temperature Range | -55 °C to +150 °C - supports operation in harsh industrial and automotive under-hood environments |
| Package | GL41 (DO-213AB) - cylindrical MELF format optimized for high-speed pick-and-place and thermal performance |
Pinout & Package
GL41 (DO-213AB) is a two-terminal axial plastic MELF package with matte tin-plated leads. The blue band identifies the cathode (positive terminal during TVS operation); the anode is the unmarked end. No PCB pad layout changes are needed when replacing other DO-213AB TVS diodes of similar power rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink | Connected to protected line; conducts surge current to ground reference during overvoltage event |
| Anode | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V rails |
| Glass-passivated planar junction | Ensures stable VBR tolerance (±5%), low leakage, and long-term reliability under thermal cycling |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; compatible with high-volume automated assembly |
| UL 94 V-0 compliant molding compound | Meets fire-safety requirements for enclosed industrial and telecom equipment enclosures |
| Unidirectional polarity only | Suitable for DC-biased lines where forward conduction must be preserved (e.g., MOSFET gate drivers) |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
|
Use Scenario: Protection of IGBT gate driver inputs against turn-off voltage spikes from snubber circuits and transformer leakage inverter stages. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between gate and source, referenced to low-inductance ground plane. Use Value: Limits gate-source voltage to ≤21.2 V during 18.9 A transients, preventing oxide breakdown in 600 V IGBTs. |
Use Scenario: Input-stage surge suppression on +48 V DC telecom rectifier outputs exposed to lightning-induced surges on distribution lines. IC Role / Device Role / Timing Role: Primary clamping device upstream of DC-DC converters and hot-swap controllers. Use Value: Clamps 400 W transients within 1 ns while maintaining <5 μA leakage at 48 V derated VWM, preserving standby efficiency. |
| Automotive Body Control Modules | Consumer Appliance Power Boards |
|
Use Scenario: Load-dump and jump-start transient suppression on 12 V microcontroller supply rails in BCMs per ISO 7637-2 Pulse 5a. IC Role / Device Role / Timing Role: Secondary protection stage after primary LC filter, directly at MCU VDD pin. Use Value: Withstands 120 V/100 ms load dump pulses via thermal mass of DO-213AB package and 150 °C TJ rating. |
Use Scenario: ESD and switching transient protection on AC-DC converter secondary-side 12 V bias rails in washing machine main control boards. IC Role / Device Role / Timing Role: Standoff-rated TVS across output capacitor, shunting inductive kickback from relay coils and triac snubbers. Use Value: 12.8 V VWM ensures no conduction during normal 12 V regulation; 21.2 V VC prevents downstream LDO dropout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA15A-E3/96 | Same 15 V nominal breakdown, but SMA package (DO-214AC); 400 W rating at 10/1000 μs; VF = 1.5 V lower at 25 A | Surface-mount flat lead package requires different footprint and stencil design; higher thermal resistance than MELF | Select when board space constraints favor rectangular SMD over cylindrical MELF, and reflow profile accommodates SMA thermal mass |
| SMAJ15A | Identical electrical specs (VBR, VC, PPPM), but non-RoHS-compliant base P/N; same DO-214AC package as P4SMA15A | Not suitable for RoHS-compliant production; lacks E3 whisker testing and JESD201 Class 1A qualification | Consider only for legacy repair or non-regulated markets where RoHS compliance is not required |
Compared with TGL41-15A-E3/96, P4SMA15A-E3/96 offers identical clamping performance in a more compact SMD footprint but with reduced thermal dissipation capability, while SMAJ15A matches electrical behavior but lacks modern process qualifications required for new industrial designs.

FAQ
What is the clamping voltage of the TGL41-15A-E3/96 under a 10/1000 μs surge?
The TGL41-15A-E3/96 has a maximum clamping voltage (VC) of 21.2 V at 18.9 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage imposed on the protected circuit during standardized surge events. The TGL41-15A-E3/96 maintains this clamping performance across its full operating temperature range.
Is the TGL41-15A-E3/96 suitable for new designs?
No - Vishay explicitly marks TGL41-15A-E3/96 as "Not For New Designs" in its official documentation (Document Number 88403, Revision 14-Nov-2023). Engineers developing new products should select qualified alternatives such as P4SMA15A-E3/96. The TGL41-15A-E3/96 remains available for legacy support and repair, but no future revisions or extended lifecycle commitments are planned.
What does the "E3/96" suffix mean in TGL41-15A-E3/96?
The "E3" suffix indicates RoHS-compliant construction with matte tin-plated leads qualified to JESD 201 Class 1A whisker testing. The "/96" denotes packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel. This packaging format is optimized for high-speed pick-and-place machines used in automated SMT assembly lines handling DO-213AB MELF devices.
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-15A-E3/96?
The GL41 (DO-213AB) package provides superior thermal mass and radial heat dissipation compared to flat SMD packages like SMA. At TL = 75 °C, the TGL41-15A-E3/96 delivers 1.0 W steady-state power dissipation on an infinite heatsink. Its cylindrical geometry allows efficient convection cooling and reduces thermal stress concentration at solder joints, supporting reliable operation up to 150 °C junction temperature.
What is the polarity configuration of the TGL41-15A-E3/96?
The TGL41-15A-E3/96 is unidirectional only, with cathode identified by a blue band on the body. During normal operation, the cathode is positive relative to the anode. This configuration enables forward conduction for surge current sinking while blocking reverse leakage up to 12.8 V (VWM). The device cannot be used in AC-coupled or bidirectional protection applications.
