Product details
Overview
TGL41-18A-E3/97 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), 17.1–18.9 V breakdown voltage (VBR), and 25.2 V clamping voltage (VC) at 15.9 A peak pulse current - used to protect MOSFETs and sensor signal lines in industrial power supplies.
For engineers reviewing the TGL41-18A-E3/97 datasheet, TGL41-18A-E3/97 pinout, TGL41-18A-E3/97 application, or TGL41-18A-E3/97 equivalent, key selection criteria include unidirectional polarity, 15.3 V stand-off voltage (VWM), 5.0 μA max reverse leakage, 1.0 W steady-state power dissipation, and compliance with J-STD-020 MSL level 1.
Technical Context
This TVS diode employs a glass-passivated planar junction for stable breakdown behavior and low incremental surge resistance. Its fast response time and excellent clamping capability are enabled by low-junction-capacitance design optimized for transient suppression on low-voltage DC rails and analog signal paths.
Rated for -55 °C to +150 °C operating junction temperature, it supports high-reliability deployment in automotive body electronics and industrial motor controllers where repetitive transients from inductive switching must be suppressed without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - defines reliable conduction onset under transient stress; ensures protection starts before downstream IC damage threshold. |
| VWM | 15.3 V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below system rail. |
| VC @ IPPM | 25.2 V - clamped voltage during 15.9 A surge; determines peak stress seen by protected circuitry. |
| PPPM | 400 W - peak pulse power handling (10/1000 μs); qualifies for IEC 61000-4-5 Level 4 surge immunity. |
| IFSM | 40 A - 8.3 ms half-sine surge rating; supports robustness against accidental short-circuit events. |
| TJ max. | +150 °C - enables placement near hot components like power MOSFETs without derating concerns. |
| Polarity | Unidirectional - cathode marked with blue band; suitable only for DC-biased lines with defined ground reference. |
Pinout & Package
Package: GL41 (DO-213AB) plastic MELF case - cylindrical, surface-mountable, RoHS-compliant, matte tin-plated leads, UL 94 V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference terminal for reverse-biased operation | Connected to system ground or lowest-potential node; forms return path during clamping. |
| Cathode | Protected line connection point | Marked with blue band; connects to line being protected (e.g., 12 V supply rail or sensor output). |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Meets IEC 61000-4-5 surge immunity requirements for industrial equipment without external heat sinking. |
| Glass-passivated planar junction | Ensures stable VBR over lifetime and temperature; eliminates parameter drift due to moisture or contamination. |
| MSL Level 1 (250 °C peak reflow) | Supports standard lead-free SMT assembly without pre-baking or special handling. |
| Low 5.0 μA max reverse leakage at VWM | Minimizes standby power loss in battery-powered sensor nodes and always-on control circuits. |
| Blue-band cathode marking | Enables rapid visual polarity verification during manual inspection and automated optical alignment. |
Applications
| Industrial Motor Drive Control | Automotive Body Control Module |
|---|---|
Use Scenario: Suppresses inductive kickback from relay coils and solenoid drivers in PLC output stages. IC Role / Device Role / Timing Role: Unidirectional TVS placed across coil terminals to clamp flyback voltage spikes before they reach driver ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA18A-E3/97 | Same VWM (15.4 V), lower PPPM (400 W), but DO-214AC (SMA) package - 2.5 mm × 4.5 mm vs. MELF's 3.0 mm × 6.0 mm footprint. | Requires PCB layout change; better suited for high-density layouts where axial MELF placement is impractical. | Select when board space is constrained and reflow compatibility with SMA footprints is confirmed. |
| SMAJ18A | Identical electrical specs (VBR, VC, PPPM), same DO-214AC package, but non-RoHS legacy variant with different whisker test compliance. | No functional difference in clamping performance; not qualified for new designs requiring JESD201 Class 1A whisker resistance. | Acceptable for cost-sensitive legacy production where RoHS exemption applies and traceability is maintained. |
Compared with P4SMA18A-E3/97 and SMAJ18A, the TGL41-18A-E3/97 offers superior thermal performance in MELF form due to higher surface-area-to-volume ratio, enabling sustained operation at elevated ambient temperatures without derating - critical for enclosed industrial enclosures.

FAQ
What is the clamping voltage of the TGL41-18A-E3/97 under maximum rated surge current?
The TGL41-18A-E3/97 has a maximum clamping voltage (VC) of 25.2 V at its rated peak pulse current (IPPM) of 15.9 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-18A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-18A-E3/97 suitable for bidirectional transient protection?
No - the TGL41-18A-E3/97 is unidirectional only, with cathode marked by a blue band. It conducts only when the cathode is positive relative to the anode, making it appropriate for DC-biased lines like power rails or single-ended signal paths. For bidirectional AC or differential line protection, a separate symmetric TVS such as the SMBJ18CA would be required instead of the TGL41-18A-E3/97.
What does the "E3/97" suffix indicate in TGL41-18A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction meeting JESD201 Class 1A whisker resistance, while "/97" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 5000 units. This differs from /96 (7-inch reel, 1500 units). Both variants share identical electrical and thermal specifications - the TGL41-18A-E3/97 is fully interchangeable electrically with TGL41-18A-E3/96.
Can the TGL41-18A-E3/97 be used in automotive applications requiring AEC-Q200 qualification?
No - the TGL41-18A-E3/97 is not AEC-Q200 qualified. It is rated for industrial-grade operation (-55 °C to +150 °C) and meets J-STD-020 MSL level 1, but lacks the extended reliability testing (e.g., vibration, temperature cycling, humidity bias) required for automotive use. For AEC-Q200-compliant alternatives, consider the Automotive Grade P4SMA18AHE3_A/H or SMAJ18AHM, not the TGL41-18A-E3/97.
How does the GL41 (DO-213AB) package affect PCB layout versus SMA packages?
The GL41 (DO-213AB) MELF package requires axial placement with solderable ends and a 0.205 inch (5.2 mm) minimum pad center-to-center spacing, unlike the rectangular DO-214AC (SMA) footprint. Its cylindrical shape demands rotational alignment during pick-and-place and increases standoff height, which may impact mechanical clearance in low-profile assemblies. Layout for TGL41-18A-E3/97 must follow Vishay's recommended mounting pad dimensions - not those for SMA devices - to ensure solder joint integrity and thermal performance.
