Product details
Overview
TGL41-15A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, designed for surge protection on signal and power lines. It features 14.3 V to 15.8 V breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 21.2 V clamping voltage at 18.9 A peak pulse current, 400 W peak pulse power (10/1000 µs), and operates from −55 °C to +150 °C junction temperature.
For engineers reviewing the TGL41-15A-E3/97 datasheet, TGL41-15A-E3/97 pinout, TGL41-15A-E3/97 application, or TGL41-15A-E3/97 equivalent, this page delivers verified electrical parameters, mechanical package details, real-world protection use cases, and validated alternative options for legacy design continuity and supply chain planning.
Technical Context
The TGL41-15A-E3/97 uses a glass-passivated planar chip junction for stable avalanche breakdown and low incremental surge resistance. Its unidirectional polarity-marked by a blue cathode band-enables DC-biased line protection with fast response time and excellent clamping performance under transient stress.
Rated for 400 W peak pulse power (10/1000 µs waveform, 0.01% duty cycle), it delivers 18.9 A peak pulse current (IPPM) while maintaining 21.2 V clamping voltage (VC). Thermal derating follows Fig. 2 per JESD22-A104, with maximum junction temperature of 150 °C and power dissipation of 1.0 W on infinite heatsink at TL = 75 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - ensures reliable avalanche conduction onset above normal operating voltage |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 5 µA |
| VC @ IPPM | 21.2 V at 18.9 A - limits protected circuit voltage during 10/1000 µs transients |
| PPPM | 400 W - peak surge energy handling capability under standard lightning/surge waveform |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without degradation |
| TJ range | −55 °C to +150 °C - supports operation in automotive under-hood and industrial environments |
| Package | GL41 (DO-213AB) - MELF-style surface-mount package with matte tin-plated leads, MSL Level 1 |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable axial terminals. Polarity is marked by a blue band indicating the cathode (positive terminal under reverse bias). No internal pins - device functions as a two-terminal bidirectional-capable unidirectional TVS diode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to ground or lower-potential rail; defines directionality of clamping |
| Cathode (blue band) | Transient current sink terminal | Connected to protected line; conducts surge current to anode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF package | Enables high-volume automated placement and reflow compatibility per J-STD-002 |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling |
| 400 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial interfaces |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes voltage overshoot during transient events, protecting downstream ICs |
| MSL Level 1, 250 °C peak reflow | Supports single-pass lead-free assembly without moisture-related popcorning |
Applications

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-E3/97 | Same VWM (12.8 V), slightly higher VC (22.5 V), lower PPPM (400 W same, but rated at 1.0 kW peak for 1 ms only), DO-214AC (SMA) package | Surface-mount SMA footprint requires PCB layout change; better suited for high-density layouts with thermal relief pads | Select when board space allows SMA package and thermal management via copper pour is feasible |
| SMAJ15A | VWM = 12.8 V, VC = 24.4 V, PPPM = 400 W, DO-214AC package, higher leakage (≤5 µA vs. ≤5 µA - identical), same TJ range | Higher clamping voltage reduces margin for sensitive 3.3 V logic; requires verification of downstream IC absolute max ratings | Choose only if existing SMA footprint is fixed and clamping margin permits 24.4 V peak |
Compared with P4SMA15A-E3/97 and SMAJ15A, the TGL41-15A-E3/97 offers superior clamping performance (21.2 V) in a compact MELF form factor ideal for automated placement, though its DO-213AB package demands different reflow profile and pad geometry than SMA variants.

FAQ
What is the clamping voltage of the TGL41-15A-E3/97 under peak pulse conditions?
The TGL41-15A-E3/97 has a maximum clamping voltage (VC) of 21.2 V at 18.9 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuit nodes will not exceed 21.2 V during standardized surge events, preserving integrity of downstream 12 V–15 V logic and analog components.
Is the TGL41-15A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-15A-E3/97 as "Not For New Designs" in its official documentation (Doc. #88403, Rev. 14-Nov-2023). Engineers initiating new projects should evaluate recommended alternatives such as the P4SMA15A-E3/97. The TGL41-15A-E3/97 remains supported for legacy production and repair, with full parametric and mechanical data retained for continuity.
What does the "E3/97" suffix mean in TGL41-15A-E3/97?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 whisker resistance (Class 1A). The "/97" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units - distinct from the /96 variant (7-inch reel, 1500 units).
How does the GL41 (DO-213AB) package affect PCB layout for TGL41-15A-E3/97?
The GL41 (DO-213AB) package is a cylindrical MELF device requiring axial mounting with symmetric solder pads (0.185–0.205 inch length, 0.018–0.022 inch width). Unlike flat SMD packages, it needs precise stencil aperture design and reflow profile tuning to ensure end-cap wetting. Pad layout must accommodate 0.105–0.095 inch diameter and avoid tombstoning via balanced thermal mass.
What is the maximum operating temperature for TGL41-15A-E3/97?
The TGL41-15A-E3/97 has a maximum junction temperature (TJ) of +150 °C and an operating junction/storage temperature range of −55 °C to +150 °C. Derating begins above TA = 25 °C per Figure 2 in the datasheet; at 75 °C ambient, power dissipation drops to 1.0 W on infinite heatsink, and peak pulse capability scales linearly with junction temperature.
