Product details
Overview
TGL41-39A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, rated for 400 W peak pulse power (10/1000 μs), 37.1–41.0 V breakdown voltage, and 53.9 V clamping voltage at 7.4 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the TGL41-39A-E3/96 datasheet, TGL41-39A-E3/96 pinout, TGL41-39A-E3/96 application, or TGL41-39A-E3/96 equivalent, key selection criteria include its 33.3 V stand-off voltage, 5.0 μA max reverse leakage at VWM, unidirectional polarity with blue-band cathode marking, and compliance with J-STD-020 MSL Level 1.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its DO-213AB package enables automated placement and supports 250 °C lead-free reflow per J-STD-020.
The device operates over -55 °C to +150 °C junction temperature range and delivers stable clamping performance under repetitive 0.01% duty cycle pulses. Its 0.103 %/°C temperature coefficient of VBR ensures predictable voltage drift across thermal conditions.
Key Specifications

Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensors against flyback voltage spikes from relay or solenoid switching. IC Role / Device Role / Timing Role: Transient voltage suppressor placed across MOSFET gate-source or op-amp input pins.

IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <100 pF) guarding precision amplifier inputs without signal distortion. Use Value: 5.0 μA max reverse leakage at 33.3 V preserves loop accuracy and avoids offset errors in 16-bit DAQ systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA39A-E3/54 | Same VBR range (37.1–41.0 V), but SMA package (DO-214AC); 600 W PPPM; higher IPPM (10.3 A) | Requires PCB pad redesign; better suited for high-volume automated assembly with pick-and-place feeders | Select when board space allows larger footprint and higher surge margin is needed |
| SMBJ39A | DO-214AA package; 600 W PPPM; VC = 60.0 V at 10.3 A; slightly higher clamping voltage | Higher thermal mass supports longer surge duration; less suitable for tight VC budgets | Prefer when system-level testing shows 60.0 V clamping remains within IC absolute maximum ratings |
Compared with P4SMA39A-E3/54 and SMBJ39A, the TGL41-39A-E3/96 offers tighter VBR tolerance, lower profile MELF packaging for high-density layouts, and optimized clamping at 53.9 V-making it ideal for space-constrained industrial controllers where precise voltage limiting is critical.

FAQ
What is the clamping voltage of the TGL41-39A-E3/96 under a 10/1000 μs surge?
The TGL41-39A-E3/96 has a maximum clamping voltage (VC) of 53.9 V at 7.4 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream ICs. The TGL41-39A-E3/96 maintains this clamping performance across its full operating temperature range.
Is the TGL41-39A-E3/96 suitable for new designs?
No-the Vishay datasheet explicitly states "Not For New Designs" for the TGL41-39A-E3/96, citing the P4SMA series as the recommended alternative. While the TGL41-39A-E3/96 remains available for legacy support and repair, new designs should evaluate P4SMA39A-E3/54 or SMBJ39A. The TGL41-39A-E3/96 continues to be stocked by Aetrix Electronics for continuity of existing production.
What does the "E3/96" suffix mean in TGL41-39A-E3/96?
The "E3" suffix indicates RoHS-compliant construction meeting JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability standards. The "/96" denotes the preferred package code for 7-inch plastic tape-and-reel delivery containing 1500 units. This packaging format is optimized for high-speed SMT placement equipment used in industrial electronics manufacturing.
How is polarity identified on the TGL41-39A-E3/96?
The TGL41-39A-E3/96 uses a blue band to mark the cathode terminal, which is positive with respect to the anode under normal TVS operation. This unidirectional polarity must be observed during PCB layout: the blue band connects to the protected line (e.g., signal rail or power net), while the unmarked end connects to ground or reference. Reversing polarity prevents clamping action and may cause permanent failure.
What is the maximum reverse leakage current for the TGL41-39A-E3/96 at its stand-off voltage?
At its rated stand-off voltage (VWM) of 33.3 V and ambient temperature of 25 °C, the TGL41-39A-E3/96 exhibits a maximum reverse leakage current (ID) of 5.0 μA. This low leakage preserves signal integrity in high-impedance sensor interfaces and avoids loading effects in precision analog circuits. The TGL41-39A-E3/96 maintains this specification across its full -55 °C to +150 °C operating junction temperature range.
