Product details
Overview
TGL41-39-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 37.1–41.0 V breakdown voltage, and 53.9 V clamping voltage at 7.4 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-39-E3/96 datasheet, TGL41-39-E3/96 pinout, TGL41-39-E3/96 application, or TGL41-39-E3/96 equivalent, key selection criteria include unidirectional polarity, 33.3 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated terminals per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max forward voltage at 25 A, enabling use in DC rail protection where polarity is fixed.
The DO-213AB (GL41) MELF package supports automated placement and meets UL 94 V-0 flammability rating. Thermal derating follows JEDEC J-STD-020 MSL Level 1 (peak reflow 250 °C), and the blue band denotes cathode polarity - positive relative to anode during clamping.
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 rail without false clamping |
| VWM | 33.3 V - maximum continuous reverse working voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 53.9 V - clamped voltage seen by protected circuit during 7.4 A transient event |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform at 0.01% duty cycle |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave, supporting high-energy inductive kickback |
| TJ max | 150 °C - maximum junction temperature enabling operation in enclosed industrial enclosures |
| Package | DO-213AB (GL41) - cylindrical MELF outline with solderable matte tin ends, optimized for pick-and-place |
Pinout & Package
DO-213AB (GL41) is a two-terminal axial plastic MELF package with cathode identified by a blue band. Terminals are matte tin plated and solderable per J-STD-002 and JESD 22-B102. E3 suffix indicates JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference terminal for unidirectional clamping | Connected to system ground or low-side return path; defines forward conduction direction |
| Cathode (blue band) | Transient energy sink | Connected to protected line (e.g., +33 V rail); conducts surge current to ground when VAK > VBR |
Key Features

|---|---|
| Glass-passivated junction | Enables stable VBR tolerance (±5%) and long-term reliability under repeated surge stress |
| 400 W peak pulse power | Handles typical automotive load-dump and industrial relay-coil turn-off transients without degradation |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes overvoltage exposure to downstream ICs while maintaining margin above VWM |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 250 °C peak without preconditioning |
| RoHS-compliant E3 termination | Meets JESD 201 Class 1A whisker requirements for high-reliability industrial assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | DO-214AA (SMB) package; 33 V VWM, 53.3 V VC @ 7.5 A; 600 W PPPM | Higher power rating but larger footprint; requires PCB area increase of ~3× vs. GL41 | Select when higher surge margin is needed and board space allows SMB outline |
| P6KE36A | DO-15 axial leaded package; 36 V VWM, 58.1 V VC @ 6.9 A; 600 W PPPM | Through-hole mounting only; incompatible with automated SMT assembly | Choose only for legacy through-hole designs or prototyping with manual soldering |
Compared with SMBJ33A and P6KE36A, the TGL41-39-E3/96 offers superior board-area efficiency in MELF format, tighter VBR tolerance (±5% vs. ±10%), and guaranteed MSL Level 1 reflow compatibility - critical for high-volume industrial SMT production.

FAQ
What is the clamping voltage of the TGL41-39-E3/96 under a 10/1000 μs surge?
The TGL41-39-E3/96 has a maximum clamping voltage (VC) of 53.9 V at 7.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see no more than 53.9 V during standardized surge events. The TGL41-39-E3/96 maintains this clamping performance across its full operating temperature range of -55 °C to 150 °C.
Is the TGL41-39-E3/96 suitable for automotive applications?
Yes, the TGL41-39-E3/96 is suitable for automotive body control modules and infotainment power supplies where unidirectional transient suppression is required. Its 40 A IFSM, 150 °C TJ max, and robust glass-passivated junction meet AEC-Q101 stress test requirements when validated per application conditions. The TGL41-39-E3/96 is not AEC-Q101 certified out-of-box but is widely deployed in non-safety-critical automotive subsystems.
How does the DO-213AB (GL41) package of the TGL41-39-E3/96 compare to SMA/SMB packages in layout?
The DO-213AB (GL41) package of the TGL41-39-E3/96 measures 3.0–3.5 mm in length and 2.41–2.67 mm in diameter, occupying ~30% less PCB area than DO-214AA (SMB). Its cylindrical MELF shape enables high-density placement and eliminates orientation concerns during automated assembly. The TGL41-39-E3/96 requires specific MELF-compatible pick-and-place nozzles and stencil apertures, unlike planar SMB packages.
What is the reverse leakage current specification for the TGL41-39-E3/96 at its stand-off voltage?
The TGL41-39-E3/96 specifies a maximum reverse leakage current (ID) of 5.0 μA at its stand-off voltage (VWM) of 33.3 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in always-on industrial control circuits and preserves battery life in backup-powered telecom modules. The TGL41-39-E3/96 maintains leakage below 50 μA up to 125 °C per derating curves in the datasheet.
Does the TGL41-39-E3/96 have bidirectional capability?
No, the TGL41-39-E3/96 is strictly unidirectional, as confirmed by Vishay documentation stating "Available in uni-directional polarity only" and specifying forward voltage (VF = 3.5 V at 25 A). Its blue band marks the cathode, and it conducts only when anode is negative relative to cathode. For bidirectional protection, a separate part number (e.g., TGL41-39CA) would be required - the TGL41-39-E3/96 does not support AC or dual-polarity transient suppression.
