Product details
Overview
TGL41-91A-E3/96 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), 86.5–95.5 V breakdown voltage, and 125 V clamping voltage at 3.2 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-91A-E3/96 datasheet, TGL41-91A-E3/96 pinout, TGL41-91A-E3/96 application, or TGL41-91A-E3/96 equivalent, key selection criteria include unidirectional polarity, 77.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C junction temperature rating, 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 protection of DC-biased lines without interfering with normal operation.
The device operates within -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 with 250 °C lead-free reflow peak. Its 0.109 %/°C temperature coefficient of VBR ensures predictable voltage drift across thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 86.5 V / 95.5 V - defines minimum clamping onset threshold and maximum variation under 1.0 mA test current |
| VWM | 77.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 125 V - clamped voltage during 3.2 A 10/1000 μs transient, limiting downstream stress |
| PPPM | 400 W - peak pulse power handling per single 10/1000 μs waveform at 0.01 % duty cycle |
| IFSM | 40 A - non-repetitive forward surge rating for 8.3 ms half-sine wave, supporting inrush tolerance |
| Junction Temp | -55 °C to +150 °C - enables deployment in extended-temperature industrial and automotive under-hood environments |
| Leakage @ VWM | 5.0 μA - ensures minimal power loss and signal integrity degradation in standby mode |
Pinout & Package
Package: GL41 (DO-213AB) - hermetically sealed plastic MELF case with matte tin-plated leads, RoHS-compliant (E3 suffix), JESD201 Class 1A whisker-tested, UL 94 V-0 rated molding compound. Blue band denotes cathode (positive terminal during TVS conduction).

| Fast response time & low Rsurge | Clamps transients within picoseconds and minimizes voltage overshoot during high-di/dt events |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and standard SMT reflow without baking preconditioning |
| Automated placement compatibility | DO-213AB geometry and lead finish support high-yield pick-and-place assembly at >30,000 UPH |
Applications
| Industrial Sensor Protection | Telecom Line Interface |
|---|---|
Use Scenario: Protecting 24 V analog output lines of pressure/temperature sensors in factory automation PLC modules from relay coil flyback and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between signal line and ground, activated only during positive transients exceeding 77.8 V. Use Value: Limits induced voltage to ≤125 V during 3.2 A surges, preserving 16-bit ADC accuracy and preventing op-amp latch-up. | Use Scenario: Safeguarding RS-485 transceiver I/O pins in base station remote radio units exposed to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Standoff protector on differential bus lines, conducting only during common-mode overvoltage events above VWM. Use Value: Maintains <5 μA leakage at 77.8 V to avoid bias shift in fail-safe termination networks while clamping to 125 V. |
| Computer Power Rail | MOSFET Gate Driver Protection |
Use Scenario: Secondary-side transient suppression on +12 V auxiliary rails feeding fan controllers and SMBus interfaces in server PSUs. IC Role / Device Role / Timing Role: Parallel-connected unidirectional TVS referenced to local ground, absorbing coupled noise from adjacent switching regulators. Use Value: Withstands 400 W pulses without degradation, ensuring rail stability during multi-phase converter cross-talk events. | Use Scenario: Clamping gate-source voltage spikes on N-channel MOSFETs driving solenoids in HVAC motor control boards. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) shunt device across gate and source, triggered only when VGS exceeds 77.8 V. Use Value: Prevents gate oxide rupture by limiting VGS to 125 V during 100 ns turn-off spikes, compatible with 25 V-rated MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA91A-E3/96 | Same 91 V nominal breakdown, but SMA package (DO-214AC); 400 W rating; 132 V clamping at 3.1 A | Surface-mount flat lead vs. MELF cylindrical form - requires PCB pad redesign and affects thermal dissipation path | Choose for board space-constrained designs where DO-214AC footprint is already standardized |
| SMAJ90A | 90 V VWM, 100 V VBR min, 146 V VC @ 2.7 A; same DO-214AC package | Higher clamping voltage reduces protection margin for 125 V-rated ICs; lower IPPM limits energy absorption | Select only if legacy SMAJ footprint must be retained and system-level testing confirms 146 V clamping is acceptable |
Compared with P4SMA91A-E3/96 and SMAJ90A, the TGL41-91A-E3/96 offers superior thermal performance in high-ambient environments due to its MELF geometry and higher surge current rating (3.2 A vs. 3.1 A/2.7 A), while maintaining identical electrical protection thresholds for 91 V-class systems.

FAQ
What is the clamping voltage of the TGL41-91A-E3/96 under peak pulse conditions?
The TGL41-91A-E3/96 has a maximum clamping voltage (VC) of 125 V at 3.2 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see no more than 125 V during specified surge events. The TGL41-91A-E3/96 maintains this clamping performance across its full operating temperature range.
Is the TGL41-91A-E3/96 suitable for new designs despite Vishay's "Not For New Designs" notice?
The "Not For New Designs" designation applies to the entire TGL41 family and indicates Vishay recommends newer alternatives like the P4SMA series for future projects. However, the TGL41-91A-E3/96 remains fully manufactured, stocked, and supported for existing designs and legacy program continuity. Aetrix Electronics guarantees supply chain access and technical documentation for the TGL41-91A-E3/96 through its lifecycle management program.
What does the "E3/96" suffix mean in TGL41-91A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 1A whisker resistance. The "/96" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel - optimized for high-speed SMT placement equipment.
How does the TGL41-91A-E3/96 compare to bidirectional TVS diodes in surge protection?
The TGL41-91A-E3/96 is unidirectional only, meaning it conducts during positive transients relative to its cathode and blocks negative excursions up to its reverse standoff voltage (77.8 V). Unlike bidirectional types, it provides forward conduction capability (3.5 V VF at 25 A), making it ideal for DC-biased lines. Bidirectional variants would require higher VC and lack forward surge handling - the TGL41-91A-E3/96 delivers tighter clamping for single-polarity threats.
Can the TGL41-91A-E3/96 be used in automotive applications?
The TGL41-91A-E3/96 is rated for -55 °C to +150 °C junction temperature and meets MSL Level 1, but it is not AEC-Q200 qualified. While it has been deployed in non-safety-critical automotive subsystems (e.g., body control modules), Vishay does not certify it for automotive use. For AEC-Q200-compliant designs, engineers should evaluate qualified alternatives such as the Automotive Grade P4SMA91AHE3/96.
