Product details
Overview
TGL41-18-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping voltage transients on signal and power lines. It features 17.1 V to 18.9 V breakdown voltage (VBR), 15.3 V stand-off voltage (VWM), 25.2 V maximum clamping voltage at 15.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used in sensor interface protection for industrial control systems.
For engineers reviewing the TGL41-18-E3/97 datasheet, TGL41-18-E3/97 pinout, TGL41-18-E3/97 application, or TGL41-18-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, clamping performance under 10/1000 μs surge, thermal derating above 25 °C, and RoHS-compliant matte tin terminations per J-STD-002.
Technical Context
This TVS diode operates exclusively in unidirectional mode, with cathode marked by a blue band and anode as the unmarked end. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gates and IC inputs against inductive switching spikes.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets J-STD-020 MSL Level 1 (peak reflow 250 °C). Its 1.0 W steady-state power dissipation and 150 °C max junction temperature support continuous operation in ambient temperatures up to 75 °C when mounted on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - ensures reliable conduction onset above normal operating voltage of 15.3 V circuits |
| VWM | 15.3 V - maximum continuous reverse voltage before leakage exceeds 5 μA |
| VC @ IPPM | 25.2 V at 15.9 A - clamps transient energy to safe levels for downstream 3.3 V or 5 V logic interfaces |
| PPPM | 400 W (10/1000 μs) - handles typical ESD and load-switching surges without degradation |
| IFSM | 40 A (8.3 ms half-sine) - withstands repetitive motor drive or relay coil turn-off currents |
| TJ max | 150 °C - defines upper thermal limit for reliability modeling in enclosed industrial enclosures |
| Package | DO-213AB (GL41) - MELF form factor optimized for automated placement and high-power density |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with solderable matte tin-plated ends. Polarity is indicated by a blue band denoting the cathode (positive terminal during clamping); the opposite end is the anode (negative terminal).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Clamping output node | Connected to protected line; sinks surge current to ground or rail when VIN exceeds VBR |
| Anode (unmarked end) | Reference return path | Typically tied to system ground or negative rail; completes clamping loop during transient events |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables sub-nanosecond response and stable VBR over 1000+ surge cycles |
| MSL Level 1 rating | Supports single-reflow assembly without pre-baking; peak reflow tolerance up to 250 °C |
| Uni-directional polarity only | Optimized for DC-biased lines like sensor supply rails or MOSFET gate drivers |
| Junction capacitance <100 pF | Minimizes signal distortion on data lines up to 10 MHz (per Fig. 4, typical CJ = 40 pF @ 0 V) |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | DO-214AC (SMA) package; 10% higher VC (27.7 V); 1.5× larger footprint | Preferred where board space allows and manual rework is needed; less suited for high-density MELF layouts | Select SMAJ18A if DO-214AC is already standardized in your assembly process and thermal mass requirements exceed DO-213AB limits. |
| 1.5KE18A | DO-201AD package; 1500 W PPPM; 3× higher clamping voltage (29.2 V); 10× larger size | Used in primary-side AC/DC input stages, not signal-line protection | Choose 1.5KE18A only for bulk power rail protection where 29.2 V clamping is acceptable and PCB real estate permits large axial leads. |
Compared with SMAJ18A and 1.5KE18A, the TGL41-18-E3/97 offers superior high-density placement capability in MELF format, tighter VC tolerance (25.2 V vs. ≥27.7 V), and lower parasitic capacitance - making it optimal for high-speed sensor and communication line protection where layout area and signal fidelity are constrained.

FAQ
What is the exact breakdown voltage range for TGL41-18-E3/97?
The TGL41-18-E3/97 has a guaranteed breakdown voltage (VBR) range of 17.1 V to 18.9 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures robust margin above its 15.3 V stand-off voltage while maintaining precise clamping behavior across manufacturing lots and temperature extremes.
Does TGL41-18-E3/97 support bidirectional transient suppression?
No, TGL41-18-E3/97 is strictly unidirectional. Its blue band marks the cathode, and it conducts only when the cathode is positive relative to the anode. For bidirectional protection, Vishay offers separate part numbers such as the TGL41-18CA series - the TGL41-18-E3/97 must not be substituted in AC-coupled or dual-polarity signal paths.
What is the maximum clamping voltage of TGL41-18-E3/97 under surge conditions?
The TGL41-18-E3/97 exhibits a maximum clamping voltage (VC) of 25.2 V when subjected to its rated 15.9 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining.
Is TGL41-18-E3/97 compatible with lead-free reflow processes?
Yes, TGL41-18-E3/97 carries the E3 suffix indicating RoHS compliance and qualification to J-STD-020 MSL Level 1, with a maximum peak reflow temperature of 250 °C. Its matte tin-plated terminals meet JESD 22-B102 solderability requirements and support standard Pb-free SAC305 profiles without pre-baking.
How does the DO-213AB package of TGL41-18-E3/97 affect PCB layout?
The DO-213AB (GL41) MELF package of TGL41-18-E3/97 requires symmetrical, non-polarized pad geometry with 0.185–0.205 inch center-to-center spacing and 0.018–0.022 inch pad width. Its cylindrical shape mandates automated pick-and-place vacuum nozzles calibrated for MELF components, and orientation-independent placement eliminates polarity verification during assembly.
