Product details
Overview
TGL41-11A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, designed for clamping voltage transients on signal and power lines. It features 10.5 V to 11.6 V breakdown voltage (VBR), 9.40 V stand-off voltage (VWM), 15.6 V maximum clamping voltage at 25.6 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used in sensor interface protection and MOSFET gate drive circuits.
For engineers reviewing the TGL41-11A-E3/97 datasheet, TGL41-11A-E3/97 pinout, TGL41-11A-E3/97 application, or TGL41-11A-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, clamping performance under 10/1000 µs surge, thermal derating above 25 °C, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
The device is rated for 40 A non-repetitive forward surge current (IFSM) and supports continuous power dissipation of 1.0 W at TL = 75 °C. Junction temperature range spans –55 °C to +150 °C, with MSL Level 1 moisture sensitivity and 250 °C lead-free reflow peak temperature compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - defines precise avalanche onset window for reliable overvoltage triggering |
| VWM | 9.40 V - maximum steady-state reverse voltage before leakage exceeds 5 µA |
| VC @ IPPM | 15.6 V at 25.6 A - clamped voltage during 10/1000 µs transient, limiting downstream stress |
| PPPM | 400 W - peak surge power handling capability under standard 10/1000 µs test waveform |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, critical for inductive load switching |
| TJ max | +150 °C - enables operation in high-temperature industrial environments without derating loss |
| Package | GL41 (DO-213AB) - compact MELF outline optimized for automated placement and thermal reliability |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with axial leads. Cathode is marked by a blue band; anode is unmarked end. Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and meet JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to lower-potential side (e.g., ground or signal return); conducts during forward surge |
| Cathode (blue band) | Clamping output terminal | Connected to protected line; avalanches when reverse voltage exceeds VBR, shunting surge to anode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA11A-E3/97 | Same VWM (9.4 V) and VC (15.6 V), but in SMA package (DO-214AC); 1.0 W PD, 400 W PPPM | SMA offers higher board-level mechanical robustness and easier manual rework vs. MELF's high-density placement | Select P4SMA11A-E3/97 when board space allows larger footprint and hand-soldering or field repair is required |
| SMAJ11A-E3/97 | Identical electrical specs but rated for 400 W PPPM with tighter VBR tolerance (5% vs. TGL41-11A's ±5%); same SMA package | Preferred for automotive AEC-Q200-compliant designs requiring validated qualification evidence | Choose SMAJ11A-E3/97 for automotive-grade programs where qualification documentation and lot traceability are mandatory |
Compared with TGL41-11A-E3/97, P4SMA11A-E3/97 provides identical clamping performance in a more serviceable package, while SMAJ11A-E3/97 adds automotive qualification rigor - neither is pin-compatible due to differing DO-213AB vs. DO-214AC footprints, requiring PCB redesign.

FAQ
What is the breakdown voltage range for TGL41-11A-E3/97?
The TGL41-11A-E3/97 has a guaranteed breakdown voltage (VBR) range of 10.5 V to 11.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes from –55 °C to +150 °C, making TGL41-11A-E3/97 suitable for precision protection in regulated power domains.
Is TGL41-11A-E3/97 suitable for bidirectional transient protection?
No, TGL41-11A-E3/97 is unidirectional only, with cathode marked by a blue band and designed to clamp reverse-polarity transients on positively biased lines. For bidirectional protection, Vishay recommends pairing two TGL41-11A-E3/97 devices in series opposition or selecting a dedicated bidirectional TVS such as the SMBJ11CA-E3/97 - TGL41-11A-E3/97 itself does not support symmetrical clamping.
What is the maximum clamping voltage of TGL41-11A-E3/97 under surge conditions?
The TGL41-11A-E3/97 exhibits a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current (IPPM) of 25.6 A, tested with a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream circuit protection margining - for example, ensuring 3.3 V or 5 V logic interfaces remain below absolute maximum ratings during surge events.
Does TGL41-11A-E3/97 comply with lead-free assembly requirements?
Yes, TGL41-11A-E3/97 carries the "E3" suffix indicating RoHS compliance and matte tin-plated leads qualified for lead-free reflow up to 250 °C peak temperature per J-STD-020 MSL Level 1. Its GL41 (DO-213AB) package requires no preconditioning and supports standard 60–90 second dwell times in convection or vapor-phase reflow profiles without delamination or solder joint voiding.
Why is TGL41-11A-E3/97 marked as "Not For New Designs"?
Vishay designates TGL41-11A-E3/97 as "Not For New Designs" because newer alternatives like the P4SMA11A-E3/97 offer identical electrical performance in the more manufacturable SMA (DO-214AC) package, with broader distribution, enhanced qualification data, and longer projected lifecycle support - though TGL41-11A-E3/97 remains fully available and supported for legacy production and repair programs.
