Product details
Overview
TGL41-7.5-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage, and 11.3 V clamping voltage at 35.4 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-7.5-E3/97 datasheet, TGL41-7.5-E3/97 pinout, TGL41-7.5-E3/97 application, or TGL41-7.5-E3/97 equivalent, key selection criteria include unidirectional polarity, 6.40 V stand-off voltage, 500 μA max reverse leakage at VWM, 1.0 W steady-state power dissipation, and RoHS-compliant matte tin-plated terminals per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max instantaneous forward voltage at 25 A, enabling use in DC-biased signal or power line protection where polarity is fixed.
The device operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. Its DO-213AB package supports automated placement and complies with UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.13 V / 7.88 V - ensures reliable triggering above 6.40 V operating voltage while avoiding false clamping during normal operation |
| VWM | 6.40 V - maximum continuous reverse working voltage before significant leakage begins |
| IPPM | 35.4 A - peak surge current it can safely shunt without degradation under 10/1000 μs waveform |
| VC @ IPPM | 11.3 V - clamped voltage seen by protected circuit during worst-case transient, limiting stress on downstream components |
| PPPM | 400 W - transient energy absorption capacity for short-duration surges per industry-standard 10/1000 μs test |
| IR @ VWM | 500 μA - low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits |
| PD | 1.0 W - continuous power dissipation limit on infinite heatsink at 75 °C, defining thermal design margin |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | DO-214AA package; 7.0 V nominal VWM; 1000 μA max IR at VWM; same 400 W PPPM | Higher leakage may affect low-power sensor nodes; larger footprint than GL41 | Select when board space permits larger SMC/SMB package and higher leakage tolerance exists |
| P6KE7.5A | DO-204AC (DO-15) axial lead; 7.5 V nominal VWM; 1000 μA max IR; 600 W PPPM (10/1000 μs) | Through-hole mounting; higher pulse rating but slower response due to lead inductance | Select for legacy through-hole designs or where higher single-pulse margin justifies manual assembly |
Compared with SMBJ7.0A and P6KE7.5A, the TGL41-7.5-E3/97 offers lower leakage (500 μA vs. 1000 μA), smaller DO-213AB footprint for high-density SMT, and tighter VBR tolerance (±5 % vs. ±10 %), making it preferable for precision-clamp and space-constrained applications.

FAQ
What is the breakdown voltage range for TGL41-7.5-E3/97?
The TGL41-7.5-E3/97 has a guaranteed breakdown voltage 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 consistent clamping behavior across production lots and supports precise overvoltage margining in protected circuits.
Is TGL41-7.5-E3/97 unidirectional or bidirectional?
TGL41-7.5-E3/97 is unidirectional only, as confirmed in the Vishay datasheet revision 11-Dec-12. The blue band marks the cathode, and it conducts in forward bias-making it suitable for DC-biased lines where polarity is fixed, unlike bidirectional variants used in AC or floating-signal applications.
What does the "E3/97" suffix mean in TGL41-7.5-E3/97?
The "E3" suffix indicates RoHS-compliant construction with JESD 201 Class 1A whisker resistance; "/97" specifies packaging in 13-inch diameter plastic tape and reel, containing 5000 units. This format ensures compatibility with high-speed pick-and-place equipment and satisfies lead-free assembly requirements.
Can TGL41-7.5-E3/97 be used in place of TGL41-7.5A?
Yes-TGL41-7.5-E3/97 is the RoHS-compliant, tape-and-reel packaged version of TGL41-7.5A. Electrical specifications, DO-213AB package dimensions, and thermal ratings are identical; only packaging and compliance markings differ. No design or layout changes are required for substitution.
What is the maximum clamping voltage of TGL41-7.5-E3/97 under surge conditions?
The TGL41-7.5-E3/97 exhibits a maximum clamping voltage (VC) of 11.3 V at its rated peak pulse current of 35.4 A (10/1000 μs waveform). This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
