Product details
Overview
TGL41-20A-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), 19.0–21.0 V breakdown voltage, and 14.4 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-20A-E3/96 datasheet, TGL41-20A-E3/96 pinout, TGL41-20A-E3/96 application, or TGL41-20A-E3/96 equivalent, key selection criteria include clamping voltage (27.7 V at IPPM), stand-off voltage (17.1 V), unidirectional polarity, MELF package compatibility with automated placement, and RoHS-compliant matte tin-plated terminals.
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 VF at 25 A, enabling protection of DC-biased signal and power lines.
Rated for operation from –55 °C to +150 °C, it meets J-STD-020 MSL Level 1 (250 °C peak reflow) and UL 94 V-0 flammability. The blue band denotes cathode polarity, and its DO-213AB outline supports standard MELF mounting pad layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the maximum clamping voltage of the TGL41-20A-E3/96 under peak pulse conditions?
The TGL41-20A-E3/96 has a maximum clamping voltage (VC) of 27.7 V when subjected to its rated peak pulse current (IPPM) of 14.4 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and ensures downstream components see limited overvoltage stress during transient events. The TGL41-20A-E3/96 maintains this clamping performance across its full operating temperature range.
Is the TGL41-20A-E3/96 suitable for new designs given its "Not For New Designs" status?
The "Not For New Designs" designation for the TGL41-20A-E3/96 indicates Vishay recommends newer alternatives like the P4SMA20A-E3 for future projects, but the TGL41-20A-E3/96 remains fully available and supported for existing designs and legacy production. Aetrix Electronics maintains active inventory and supply chain continuity for the TGL41-20A-E3/96 to support ongoing manufacturing needs.
What does the "E3/96" suffix indicate in TGL41-20A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance. The "/96" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel - a standard format for high-volume automated assembly. This packaging ensures consistent feed reliability in pick-and-place systems.
How does the GL41 (DO-213AB) package of the TGL41-20A-E3/96 compare thermally to SMA packages?
The GL41 (DO-213AB) MELF package of the TGL41-20A-E3/96 provides higher surface-area-to-volume ratio and axial lead geometry that enhances convective cooling versus flat SMA packages. Its 1.0 W steady-state power dissipation rating is achieved with lower thermal resistance to ambient, making it preferred in high-power-density or high-temperature ambient applications where thermal margin is critical. The TGL41-20A-E3/96 leverages this advantage for sustained reliability under repeated surge stress.
Can the TGL41-20A-E3/96 be used in bidirectional configurations?
No - the TGL41-20A-E3/96 is specified for unidirectional polarity only, with a blue band marking the cathode. It is not rated for reverse-biased conduction beyond its specified VWM and leakage limits. For bidirectional transient suppression, a dedicated bidirectional TVS (e.g., TGL41-20CA) or back-to-back unidirectional devices would be required. The TGL41-20A-E3/96 must be oriented correctly in-circuit to ensure proper clamping function.
