Product details
Overview
TGL41-75A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, rated for 71.3–78.8 V breakdown voltage, 64.1 V stand-off voltage, and 400 W peak pulse power (10/1000 μs), used to protect MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-75A-E3/96 datasheet, TGL41-75A-E3/96 pinout, TGL41-75A-E3/96 application, or TGL41-75A-E3/96 equivalent, key selection criteria include clamping voltage (103 V at 3.9 A), low incremental surge resistance, unidirectional polarity with blue-band cathode marking, 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 fast response (<1 ns), optimized for single-pulse transient suppression under 10/1000 μs waveform conditions. Its thermal design supports operation up to +150 °C junction temperature with 1.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature.
The device exhibits a positive temperature coefficient of breakdown voltage (+0.108 %/°C), enabling predictable voltage drift over temperature, and meets UL 94 V-0 flammability requirements in its molded compound housing. Polarity is fixed unidirectional, with cathode identified by blue band and marked as positive terminal during clamping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA75A-E3/96 | Same VWM (64.1 V) and VC (103 V), but in DO-41 package (axial leaded, larger footprint) | Less suitable for high-density automated placement; lower thermal mass affects surge derating above 75 °C | Preferred where board space permits and legacy DO-41 tooling is in use |
| SMAJ75A | DO-214AC (SMA) package; identical electrical specs but 1.5× higher junction-to-ambient thermal resistance | Requires larger copper pour for equivalent thermal performance; not MELF-compatible for tape-and-reel automation | Chosen when existing SMA footprint reuse is prioritized over MELF placement efficiency |
Compared with TGL41-75A-E3/96, P4SMA75A-E3/96 offers identical clamping performance in a legacy axial package, while SMAJ75A trades MELF manufacturability for surface-mount compatibility-neither is pin-compatible due to differing package geometries and terminal configurations.

FAQ
What is the maximum clamping voltage of the TGL41-75A-E3/96 under specified test conditions?
The TGL41-75A-E3/96 has a maximum clamping voltage (VC) of 103 V when subjected to its rated peak pulse current of 3.9 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 TGL41-75A-E3/96 maintains this clamping performance across its full operating temperature range, supporting robust design margins in harsh environments.
Is the TGL41-75A-E3/96 suitable for new designs given its "Not For New Designs" status?
No-the TGL41-75A-E3/96 is marked "Not For New Designs" by Vishay, indicating it is in last-time-buy status with no future revisions planned. While fully functional and supported for existing production, new designs should migrate to the recommended alternative, P4SMA75A-E3/96, which shares identical electrical characteristics but uses the DO-41 package. The TGL41-75A-E3/96 remains viable for legacy repair, maintenance, and continuity builds where MELF form factor is mandatory.
How does the blue band on the TGL41-75A-E3/96 identify polarity, and why is this critical?
The blue band on the TGL41-75A-E3/96 marks the cathode terminal, which must be connected toward the protected line (e.g., VCC or signal trace), while the anode connects to ground. Correct orientation ensures unidirectional clamping action-reverse installation prevents conduction during overvoltage events and may cause catastrophic failure. This polarity marking is essential for automated optical inspection (AOI) and eliminates ambiguity during high-speed MELF placement, directly impacting field reliability of the TGL41-75A-E3/96.
What is the thermal derating behavior of the TGL41-75A-E3/96 above 25 °C ambient?
The TGL41-75A-E3/96 follows Vishay's standard derating curve: peak pulse power remains at 400 W up to TA = 25 °C, then linearly decreases to 200 W at TA = 91 °C, and further drops beyond that point per Figure 2 in document 88403. Steady-state power dissipation (PD) is rated at 1.0 W on infinite heatsink at TL = 75 °C, with proportional reduction at higher lead temperatures. These curves ensure predictable performance of the TGL41-75A-E3/96 in thermally demanding enclosures like motor drive cabinets.
Does the TGL41-75A-E3/96 meet any industry-standard surge immunity requirements out of the box?
The TGL41-75A-E3/96 is designed to meet IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) when properly implemented with appropriate PCB layout-i.e., short traces, low-inductance grounding, and adequate copper pour. Its 400 W rating aligns with the 10/1000 μs waveform defined in ANSI/IEEE C62.35, and its 40 A IFSM supports compliance with ISO 7637-2 Pulse 5a (load dump). System-level validation is required, but the TGL41-75A-E3/96 provides foundational protection capability for these standards.
