Overview
TGL41-24A-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), 22.8–25.2 V breakdown voltage, and 33.2 V clamping voltage at 12.0 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-24A-E3/97 datasheet, TGL41-24A-E3/97 pinout, TGL41-24A-E3/97 application, or TGL41-24A-E3/97 equivalent, key selection criteria include unidirectional polarity, 20.5 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
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 forward voltage at 25 A, enabling robust protection during positive-going transients on DC-biased lines.
The device operates across -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (250 °C lead-free reflow peak). Its 0.097 %/°C temperature coefficient of VBR ensures stable clamping behavior over thermal variation in industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA24A-E3/97 | Same 24 V nominal rating, but SMA package (DO-214AC); 400 W PPPM, 33.2 V VC, 12.0 A IPPM; higher thermal resistance due to smaller body | Suitable for PCBs with surface-mount land patterns designed for SMA; less suited for high-vibration environments where MELF mechanical robustness is preferred | Select P4SMA24A-E3/97 only if board layout already uses SMA footprints and thermal management accommodates higher junction rise |
| SMAJ24A | DO-214AC package; identical electrical specs (VBR 22.8–25.2 V, VC 33.2 V), but lower surge rating (400 W same, yet IFSM = 30 A vs. 40 A) | Used in cost-sensitive consumer designs where 30 A surge margin suffices; lacks E3 whisker-test compliance and J-STD-020 MSL Level 1 certification | Choose SMAJ24A only for non-automotive, non-industrial applications where full Vishay qualification is not required |
Compared with P4SMA24A-E3/97 and SMAJ24A, the TGL41-24A-E3/97 offers superior mechanical stability via MELF construction, verified MSL Level 1 handling, and higher 40 A IFSM - making it preferred for industrial motor controls and automotive body electronics requiring long-term reliability under thermal cycling and vibration.

FAQ
What is the maximum clamping voltage of the TGL41-24A-E3/97 under specified test conditions?
The TGL41-24A-E3/97 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current of 12.0 A using a 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-24A-E3/97 maintains this clamping performance across its full operating temperature range due to its low 0.097 %/°C VBR temperature coefficient.
Is the TGL41-24A-E3/97 suitable for new designs despite Vishay's "Not For New Designs" notice?
The "Not For New Designs" notice applies to the entire TGL41 family and indicates Vishay recommends newer alternatives like the P4SMA series for future product development. However, the TGL41-24A-E3/97 remains fully manufactured, stocked, and supported for legacy design refreshes, repair, and continuity programs. Aetrix Electronics guarantees supply continuity and full technical documentation for the TGL41-24A-E3/97 through its industrial lifecycle management program.
How does the GL41 (DO-213AB) package of the TGL41-24A-E3/97 differ from standard SMA packages in terms of reliability?
The GL41 (DO-213AB) MELF package of the TGL41-24A-E3/97 provides superior mechanical robustness and thermal performance compared to flat SMA (DO-214AC) devices. Its cylindrical geometry resists cracking under thermal cycling and board flexure, while its larger surface area improves heat dissipation. The TGL41-24A-E3/97 also achieves MSL Level 1 per J-STD-020 - a qualification not typically met by standard SMA-packaged TVS diodes - ensuring reliable lead-free reflow without popcorn failure.
What is the reverse leakage current specification for the TGL41-24A-E3/97 at its maximum working voltage?
At its maximum stand-off voltage (VWM) of 20.5 V and TA = 25 °C, the TGL41-24A-E3/97 exhibits a maximum reverse leakage current (ID) of 5.0 μA. This low leakage ensures minimal power loss in always-on circuits and preserves signal integrity on high-impedance sensor lines. The TGL41-24A-E3/97 maintains this leakage performance up to 125 °C, with gradual increase governed by its specified temperature coefficient.
Does the TGL41-24A-E3/97 support bidirectional transient suppression?
No, the TGL41-24A-E3/97 is unidirectional only, as confirmed in Vishay's datasheet features and electrical tables. It functions as a reverse-biased avalanche diode for positive transients on grounded lines and conducts forward current up to 3.5 V at 25 A. For bidirectional protection, a separate device such as the TGL41-24CA-E3/97 (if available) or a dual-diode configuration would be required. The TGL41-24A-E3/97's blue band clearly marks the cathode for correct orientation during placement.
