Product details
Overview
TGL41-39-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping voltage transients on signal and power lines. It features 37.1 V minimum breakdown voltage (VBR), 33.3 V standoff voltage (VWM), 53.9 V maximum clamping voltage at 7.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and sensor ICs in industrial control systems.
For engineers reviewing the TGL41-39-E3/97 datasheet, TGL41-39-E3/97 pinout, TGL41-39-E3/97 application, or TGL41-39-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 150 °C max junction temperature, RoHS-compliant matte tin plating, and J-STD-020 MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates exclusively in unidirectional mode, with cathode denoted by a blue band and forward voltage of 3.5 V at 25 A. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance under repetitive transient stress.
The device complies with ANSI/IEEE C62.35 for transient suppression standards and is rated for 400 W peak pulse power up to 91 V, derating to 200 W above that threshold. Thermal performance is specified across -55 °C to +150 °C operating junction range with 1.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature.
Key Specifications

|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - defines reliable conduction onset under transient overvoltage |
| VWM | 33.3 V - maximum continuous reverse voltage before leakage exceeds 5 μA |
| VC @ IPPM | 53.9 V at 7.4 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36A | DO-214AA package; 36 V VWM, 58.1 V VC @ 6.9 A; 600 W PPPM | Higher clamping voltage and larger footprint; better suited for PCB space-tolerant designs | Select when higher surge margin is needed and MELF placement is not required |
| P6KE36A | DO-15 axial package; 36 V VWM, 58.1 V VC @ 6.9 A; 600 W PPPM | Manual assembly compatible; no automated placement support; lower thermal mass | Choose for prototyping or low-volume production where reel-based SMT is unavailable |
Compared with SMBJ36A and P6KE36A, the TGL41-39-E3/97 offers tighter VBR tolerance (±5.4 % vs ±10 %), smaller DO-213AB footprint for dense layouts, and superior moisture resistance (MSL Level 1), making it optimal for high-reliability automated manufacturing.

FAQ
What is the breakdown voltage range for TGL41-39-E3/97?
The TGL41-39-E3/97 has a guaranteed breakdown voltage (VBR) range of 37.1 V to 41.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5.4 % tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design in 36 V nominal systems.
Is TGL41-39-E3/97 RoHS compliant and halogen-free?
Yes, TGL41-39-E3/97 is RoHS compliant (per Directive 2011/65/EU) and meets JEDEC JS709A halogen-free requirements. The "E3" suffix confirms matte tin plating compliant with JESD 22-B102 solderability and JESD 201 Class 1A whisker resistance, making it suitable for lead-free reflow and long-life industrial deployments.
What is the maximum clamping voltage of TGL41-39-E3/97 under surge conditions?
The TGL41-39-E3/97 exhibits a maximum clamping voltage (VC) of 53.9 V at 7.4 A peak pulse current (IPPM) using the standard 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.
Can TGL41-39-E3/97 be used in bidirectional configurations?
No, TGL41-39-E3/97 is strictly unidirectional and must be oriented with the blue-banded cathode toward the higher-potential node. Bidirectional operation is not supported - for AC or dual-polarity protection, separate unidirectional devices or dedicated bidirectional TVS diodes (e.g., TGL41-39CA) are required.
What is the moisture sensitivity level (MSL) rating for TGL41-39-E3/97?
TGL41-39-E3/97 is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/85 % RH and subjected to peak reflow temperatures up to 250 °C without baking. This eliminates pre-reflow drying steps and simplifies SMT line integration for high-throughput manufacturing.
