Product details
Overview
TGL41-150-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), 143–158 V breakdown voltage (VBR), and 207 V clamping voltage (VC) at 0.97 A peak pulse current - deployed for surge protection on power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the TGL41-150-E3/97 datasheet, TGL41-150-E3/97 pinout, TGL41-150-E3/97 application, or TGL41-150-E3/97 equivalent, key selection criteria include unidirectional polarity, 128 V stand-off voltage (VWM), 5 μA max reverse leakage, 150 °C junction temperature rating, and RoHS-compliant matte tin-plated terminals per J-STD-002.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when transient voltage exceeds its breakdown threshold (143–158 V). Its glass-passivated junction ensures stable VBR tolerance and low incremental surge resistance, enabling consistent clamping performance under repetitive 0.01% duty cycle surges.
The DO-213AB (GL41) MELF package provides high thermal mass and automated placement compatibility, while the blue band denotes cathode polarity - critical for correct orientation in DC-biased protection paths. It meets MSL Level 1 (250 °C peak reflow) and UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 143 V / 158 V - defines precise voltage threshold at which avalanche conduction begins under 1.0 mA test current |
| VWM | 128 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA |
| VC @ IPPM | 207 V - clamped voltage seen by protected circuit during 0.97 A 10/1000 μs transient |

FAQ
What is the clamping voltage of the TGL41-150-E3/97 under peak pulse conditions?
The TGL41-150-E3/97 has a maximum clamping voltage (VC) of 207 V when subjected to its rated peak pulse current of 0.97 A using a 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream components remain within safe operating limits.
Is the TGL41-150-E3/97 suitable for bidirectional transient protection?
No, the TGL41-150-E3/97 is strictly unidirectional and must be installed with correct polarity - the blue band identifies the cathode, which connects to the line being protected. For bidirectional applications, such as AC lines or differential buses, a separate bidirectional TVS like the TGL41-150CA or equivalent must be selected instead of the TGL41-150-E3/97.
Does the TGL41-150-E3/97 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-150-E3/97 carries the E3 suffix indicating full RoHS compliance and qualification to JESD 201 Class 1A whisker resistance. Its matte tin-plated terminals are solderable per J-STD-002 and compatible with standard lead-free reflow profiles up to 250 °C peak temperature, satisfying IPC-J-STD-020 MSL Level 1 requirements.
What is the maximum operating temperature for the TGL41-150-E3/97?
The TGL41-150-E3/97 has a maximum junction temperature (TJ) rating of 150 °C, with an operating and storage temperature range of –55 °C to +150 °C. Derating of peak pulse power begins above 25 °C ambient per Figure 2 in the datasheet, and thermal design must ensure junction temperature remains within this limit under worst-case surge and steady-state power dissipation.
How does the DO-213AB (GL41) package of the TGL41-150-E3/97 compare to SMA/SMB packages in surge handling?
The DO-213AB (GL41) MELF package of the TGL41-150-E3/97 offers superior thermal mass and lower thermal resistance compared to flat SMT packages like SMA or SMB, enabling more consistent 400 W peak pulse power performance across repeated surges. Its cylindrical geometry also supports higher mechanical stability during thermal cycling, making it preferred for high-reliability industrial deployments where the TGL41-150-E3/97 is specified.
