Product details
Overview
TGL41-33A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 31.4 V minimum breakdown voltage (VBR), 28.2 V standoff voltage (VWM), 45.7 V clamping voltage at 8.8 A peak pulse current (VC), and 400 W peak pulse power rating (10/1000 µs). It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-33A-E3/96 datasheet, TGL41-33A-E3/96 pinout, TGL41-33A-E3/96 application, or TGL41-33A-E3/96 equivalent, key selection factors include its unidirectional polarity, 0.101 %/°C VBR temperature coefficient, 5 µA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated planar junction for stable breakdown behavior and low incremental surge resistance. Its fast response time and excellent clamping capability are enabled by low-junction-capacitance design optimized for transient suppression on signal and power lines.
The device operates within -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and derates linearly above 25 °C ambient per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V at 1.0 mA test current - defines reliable conduction onset under transient stress |
| VWM | 28.2 V - maximum continuous reverse voltage before significant leakage begins |
| VC @ IPPM | 45.7 V at 8.8 A (10/1000 µs) - clamped voltage seen by protected circuit during worst-case surge |
| PPPM | 400 W - peak transient energy absorption capacity without failure |
| IFSM | 40 A - surge current handling for 8.3 ms half-sine waveform, critical for inductive load switching |
| TJ max | +150 °C - maximum allowable junction temperature for sustained operation and reliability |
| Temp Coeff | 0.101 %/°C - predictable VBR drift over temperature, enabling accurate system-level margining |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical glass-body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal during TVS conduction); no internal leads - terminals are the two axial ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-biased operation | Connected to ground or lower-potential rail; reverse voltage applied between cathode and this terminal |
| Cathode (blue band end) | Transient current sink during clamping | Connected to protected line; conducts surge current to anode/ground when VLINE exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF package | Enables high-volume automated placement and provides robust mechanical integrity for board-level shock/vibration environments |
| Glass-passivated planar junction | Ensures stable, repeatable breakdown voltage and low leakage across temperature and lifetime |
| 400 W peak pulse power (10/1000 µs) | Supports protection of 24 V industrial control inputs against IEC 61000-4-5 Level 3 surges (1 kV/42 Ω) |
| MSL Level 1 (250 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or special handling |
| Unidirectional polarity only | Suitable for DC-biased lines where reverse conduction must be blocked during normal operation |
Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
Use Scenario: Protection of gate drivers and logic inputs against flyback voltage from relay coils and solenoid actuation. IC Role / Device Role: Transient voltage suppressor placed across relay coil or in series with microcontroller GPIO.

IC Role / Device Role: Low-leakage (≤5 µA) TVS on analog input traces adjacent to AC mains-coupled relays. Use Value: Prevents ESD and relay-switching transients from corrupting 12-bit ADC readings without adding offset error via leakage current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA33A-E3/96 | Same VWM (28.2 V), slightly higher VC (53.3 V), lower PPPM (400 W same, but lower IPPM rating due to SMA package thermal limits) | SMA package has larger footprint and lower power density; less suitable for space-constrained MELF-optimized layouts | Select P4SMA33A-E3/96 only if board redesign allows SMA footprint and thermal relief is verified |
| SMAJ33A | Higher VC (53.3 V), same VWM, identical PPPM, but SMA package with 2.5 mm lead spacing vs. MELF's 0 mm pitch | Requires PCB pad revision; not drop-in; higher parasitic inductance may degrade clamping speed on fast edges | Choose SMAJ33A only when legacy SMA tooling exists and layout change is acceptable |
Compared with TGL41-33A-E3/96, both alternatives use SMA packaging with greater board area, higher clamping voltage, and reduced suitability for high-density automated assembly-TGL41-33A-E3/96 remains optimal for MELF-optimized, space-constrained, and high-reliability industrial designs requiring precise 45.7 V clamping.

FAQ
What is the clamping voltage of the TGL41-33A-E3/96 under standard test conditions?
The TGL41-33A-E3/96 has a maximum clamping voltage (VC) of 45.7 V when subjected to an 8.8 A peak pulse current with a 10/1000 µs waveform at TA = 25 °C. This value is measured across the device terminals during transient conduction and represents the upper voltage limit imposed on the protected circuit during surge events.
Is the TGL41-33A-E3/96 suitable for bidirectional transient protection?
No, the TGL41-33A-E3/96 is unidirectional only, with a blue band marking the cathode. It conducts only when the cathode is positive relative to the anode. For bidirectional protection, a separate symmetric TVS or back-to-back configuration would be required - the TGL41-33A-E3/96 itself does not support reverse conduction.
What is the maximum operating temperature for the TGL41-33A-E3/96?
The TGL41-33A-E3/96 has a maximum junction temperature (TJ) of +150 °C and an operating junction and storage temperature range of -55 °C to +150 °C. Derating of peak pulse power begins above TA = 25 °C per Figure 2 in the datasheet, and thermal design must ensure junction temperature remains within this limit under worst-case power dissipation.
Does the TGL41-33A-E3/96 meet lead-free reflow requirements?
Yes, the TGL41-33A-E3/96 meets MSL Level 1 per J-STD-020 with a maximum lead-free reflow peak temperature of 250 °C. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, and the E3 suffix confirms compliance with JESD 201 Class 1A whisker testing.
Why is the TGL41-33A-E3/96 marked as "Not For New Designs"?
The "Not For New Designs" designation applies to the entire TGL41 family per Vishay documentation (Rev. 14-Nov-2023), indicating Vishay recommends newer alternatives like the P4SMA series for new projects. However, TGL41-33A-E3/96 remains fully supported for existing designs, with active manufacturing, full datasheet specifications, and guaranteed supply continuity through Aetrix Electronics.
