Product details
Overview
TGL41-7.5A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 7.13 V to 7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), and 400 W peak pulse power (10/1000 μs). It clamps transients to ≤11.3 V at 35.4 A peak pulse current and is used for protecting MOSFETs, ICs, and sensor signal lines against inductive switching surges in industrial and telecom equipment.
For engineers reviewing the TGL41-7.5A-E3/97 datasheet, TGL41-7.5A-E3/97 pinout, TGL41-7.5A-E3/97 application, or TGL41-7.5A-E3/97 equivalent, key selection criteria include unidirectional polarity, 10 mA test current, 500 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
Technical Context
The TGL41-7.5A-E3/97 employs a glass-passivated planar junction structure optimized for fast transient response and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability while suppressing reverse transients above VWM.
Designed per ANSI/IEEE C62.35 standards, it delivers 400 W peak pulse power under 10/1000 μs waveform with 0.01% duty cycle, derating linearly above 25 °C ambient per published curves. Clamping occurs within picoseconds, with VF = 3.5 V at 25 A forward surge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 7.13 V / 7.88 V - defines minimum voltage at which device enters avalanche breakdown under 10 mA test current |
| VWM | 6.40 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 35.4 A - peak pulse current it can safely shunt during 10/1000 μs transient without damage |
| VC | 11.3 V - maximum clamped voltage across device at IPPM, directly limiting stress on protected circuitry |
| PPPM | 400 W - peak transient energy absorption capacity under standard 10/1000 μs waveform |
| IFSM | 40 A - maximum non-repetitive forward surge current (8.3 ms half-sine), critical for inrush protection |
| TJ max | 150 °C - maximum allowable junction temperature, constraining thermal design margin in PCB layout |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal under normal TVS operation); RoHS-compliant E3 suffix meets JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to ground or low-side reference; reverse-biased during transient suppression |
| Cathode (blue band) | Transient input node | Connected to protected line; conducts avalanche current to anode when VIN exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF packaging | Enables high-volume automated placement and reflow compatibility without lead bending or tombstoning |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress |
| 400 W peak pulse power (10/1000 μs) | Provides robust protection against common industrial switching transients and lightning-induced surges |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 250 °C peak without moisture-related popcorn failure |
| Unidirectional polarity only | Simplifies circuit integration where forward conduction path is required or bidirectional noise is absent |
Applications
| Industrial Motor Control | Telecom Power Interface |
|---|---|
Use Scenario: Protecting gate drivers and logic inputs of IGBTs/MOSFETs from inductive kickback during motor coil de-energization. IC Role / Device Role / Timing Role: Unidirectional TVS placed between gate and source to clamp negative-going spikes below -0.7 V and positive transients above VBR. Use Value: Limits gate-source voltage excursion to ≤11.3 V, preventing oxide breakdown and ensuring >100,000-cycle reliability under 35.4 A surge conditions. | Use Scenario: Safeguarding DC power input rails (e.g., 48 V telecom supplies) against load dump and hot-swap transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main supply line upstream of DC-DC converters and PMICs. Use Value: Absorbs up to 400 W of transient energy within nanoseconds, holding rail voltage ≤11.3 V to avoid brownout or latch-up in downstream regulators. |
| Automotive Sensor Signal Lines | Consumer Appliance Microcontroller I/O |
Use Scenario: Shielding analog and digital signal lines (e.g., CAN, LIN, or PWM feedback) from ESD and cable discharge events in engine bay sensors. IC Role / Device Role / Timing Role: Point-of-entry protection on harness connectors, placed before ESD diode arrays or internal MCU protection. Use Value: Responds in <1 ps to clamp 8 kV contact ESD to ≤11.3 V, preserving signal integrity and avoiding false triggering in 12-bit ADC references. | Use Scenario: Securing microcontroller GPIOs and UART lines in white goods (e.g., washing machine control boards) exposed to relay coil transients. IC Role / Device Role / Timing Role: Localized TVS on each I/O trace, with cathode tied to signal line and anode to system ground plane. Use Value: Withstands 500 μA leakage at 6.40 V, enabling direct placement without pull-up interference, while clamping 35.4 A surges to safe levels for 3.3 V/5 V logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA7.5-E3/97 | Same VBR range (7.09–7.83 V), but SMA package (DO-214AC); 400 W PPPM, 35.5 A IPPM, 11.3 V VC; higher thermal resistance due to surface-mount epoxy body | Requires different footprint and reflow profile; less suitable for high-vibration environments than MELF | Choose for space-constrained PCBs where DO-214AC layout already exists and vibration is minimal |
| SMBJ7.5A | DO-214AA package; identical electrical specs (VBR: 7.09–7.83 V, VC: 11.3 V, IPPM: 35.5 A), but 600 W PPPM rating and higher IFSM (100 A) | Higher surge margin supports longer transient durations; larger body increases board area use by ~3× | Choose when legacy SMB layout is fixed and enhanced 600 W surge headroom is required |
Compared with P4SMA7.5-E3/97 and SMBJ7.5A, the TGL41-7.5A-E3/97 offers superior mechanical robustness in high-vibration settings via its MELF construction, lower thermal resistance than SMA packages, and tighter VBR tolerance (±5% vs ±6%), making it preferred for precision clamping in automotive and industrial motion control.

FAQ
What is the breakdown voltage range of the TGL41-7.5A-E3/97?
The TGL41-7.5A-E3/97 has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting 5 V or 6 V logic interfaces without premature conduction.
Is the TGL41-7.5A-E3/97 suitable for bidirectional transient protection?
No, the TGL41-7.5A-E3/97 is unidirectional only, with a blue band marking the cathode. It conducts in forward bias and clamps reverse transients above VBR. For bidirectional protection, Vishay recommends separate devices like the P6SMB7.5CA or dual-diode configurations - the TGL41-7.5A-E3/97 must not be used where AC-coupled or symmetrical surge immunity is required.
What is the maximum clamping voltage of the TGL41-7.5A-E3/97 under surge conditions?
The TGL41-7.5A-E3/97 clamps to a maximum of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 μs waveform). This value is measured and guaranteed per datasheet Fig. 5, and represents the upper limit of voltage imposed on protected circuitry during worst-case transient events, enabling safe interfacing with 12 V tolerant inputs.
Does the TGL41-7.5A-E3/97 meet RoHS and lead-free requirements?
Yes, the TGL41-7.5A-E3/97 carries the E3 suffix, confirming full RoHS compliance (per Directive 2011/65/EU) and commercial-grade qualification. Its matte tin-plated leads satisfy J-STD-002 solderability and JESD 22-B102 durability standards, and it passes JESD 201 Class 1A whisker testing - all verified in Vishay Document Number 88403.
Why is the TGL41-7.5A-E3/97 marked as "Not For New Designs"?
The "Not For New Designs" status applies to the entire TGL41 family per Vishay's November 2023 revision notice, indicating planned obsolescence. However, TGL41-7.5A-E3/97 remains actively manufactured and supported for existing designs; Aetrix Electronics maintains strategic inventory and offers lifecycle coordination to ensure continuity until migration to alternatives like the P4SMA7.5-E3/97 is completed.
