Product details
Overview
TGL41-47-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) MELF package, designed for clamping voltage transients on power and signal lines. It features 44.7 V minimum breakdown voltage (VBR), 40.2 V standoff voltage (VWM), 6.2 A peak pulse current (IPPM) under 10/1000 μs waveform, and 64.8 V maximum clamping voltage (VC) at rated surge - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-47-E3/96 datasheet, TGL41-47-E3/96 pinout, TGL41-47-E3/96 application, or TGL41-47-E3/96 equivalent, key selection criteria include unidirectional polarity, 400 W peak pulse power rating, 150 °C max junction temperature, RoHS-compliant matte tin terminals, and MSL Level 1 moisture sensitivity - critical for automated SMT placement and high-reliability transient suppression in power supply rails and interface lines.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable VBR tolerance (±5% typical per family spec) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and inductive switching transients.
The DO-213AB (GL41) MELF package provides uniform thermal dissipation and mechanical robustness for reflow soldering, with blue band marking the cathode terminal. It is rated for 1.0 W steady-state power dissipation at TL = 75 °C and supports repetitive surge duty cycles up to 0.01% at 400 W peak pulse power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 44.7 V / 49.4 V - defines precise avalanche initiation range for reliable clamping onset |
| VWM | 40.2 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA |
| VC @ IPPM | 64.8 V - clamped voltage during 6.2 A 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 400 W - peak transient energy absorption capability under standard 10/1000 μs waveform |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, supporting inrush and fault conditions |
| Junction Temp Range | –55 °C to +150 °C - enables operation in extended industrial and automotive-adjacent environments |
| Package | DO-213AB (GL41) - MELF-style glass-body package optimized for automated placement and thermal reliability |
Pinout & Package
DO-213AB (GL41) is a cylindrical, glass-passivated MELF package with two solderable end terminals. The blue band identifies the cathode (positive terminal under reverse bias), consistent with unidirectional TVS operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-bias operation | Connected to ground or lower-potential rail; carries surge current into cathode during clamping |
| Cathode (blue band end) | Clamping output node | Connected to protected line; conducts avalanche current when VLINE exceeds VBR, clamping to ≤64.8 V |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-line) without derating |
| Glass passivated chip junction | Ensures long-term stability of VBR and low leakage (<5 μA at VWM) across temperature and life cycle |
| MSL Level 1 (250 °C peak reflow) | Supports single-pass lead-free reflow without preconditioning, reducing manufacturing complexity |
| Uni-directional polarity only | Simplifies layout vs. bi-directional parts; eliminates need for series blocking diode in DC rail protection |
| RoHS-compliant, JESD201 Class 1A whisker-tested | Meets global environmental compliance and high-reliability requirements for industrial and telecom BOMs |
Applications
| Power Supply Input Protection | Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 24 V DC industrial power inputs from inductive kickback and lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp transients above 40.2 V. Use Value: Limits voltage seen by upstream DC/DC converter and downstream logic to ≤64.8 V, preventing latch-up or gate oxide damage. | Use Scenario: Safeguarding analog outputs of temperature/pressure sensors connected to PLC analog input modules. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to shunt ESD and cable discharge events. Use Value: Maintains signal integrity below 10.5 mV/V error shift by suppressing transients before they reach precision ADC front-end. |
| MOSFET Gate Driver Protection | Telecom Line Interface Protection |
Use Scenario: Shielding high-side N-channel MOSFET gate drivers in motor control H-bridges from cross-conduction spikes. IC Role / Device Role / Timing Role: TVS placed between gate and source to clamp Miller-induced overshoot during fast switching. Use Value: Prevents gate oxide breakdown by holding VGS ≤64.8 V during 100 ns transients, preserving driver FET lifetime. | Use Scenario: Protecting RS-485 transceiver data lines in outdoor base station backhaul units exposed to induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS on each differential pair, referenced to local ground plane. Use Value: Ensures bus remains operational after 4 kV contact ESD (IEC 61000-4-2) with <1 μs recovery and no data corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ43A (DO-214AA) | Higher VC (69.4 V), same VWM (36.8 V), 600 W PPPM, surface-mount SMB package | Requires larger PCB footprint; better suited for higher-energy surges but less space-efficient than MELF | Select when surge energy exceeds 400 W or board layout allows SMB footprint |
| 1.5KE43A (DO-201AD) | Same VBR/VWM range, 69.4 V VC, 1500 W PPPM, axial-leaded through-hole package | Not suitable for automated SMT; intended for prototyping or low-volume through-hole assemblies | Choose only for manual assembly or legacy through-hole designs requiring higher surge margin |
Compared with SMBJ43A and 1.5KE43A, the TGL41-47-E3/96 offers superior space efficiency in high-density SMT layouts, tighter VBR tolerance, and guaranteed MSL Level 1 compatibility - making it optimal for volume-manufactured industrial controllers where placement yield and thermal cycling reliability are critical.

FAQ
What is the exact breakdown voltage range for TGL41-47-E3/96?
The TGL41-47-E3/96 has a specified breakdown voltage (VBR) range of 44.7 V (minimum) to 49.4 V (maximum) at 1.0 mA test current, per Vishay Document 88403. This ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for coordinating with system overvoltage thresholds.
Is TGL41-47-E3/96 suitable for bidirectional transient protection?
No, the TGL41-47-E3/96 is unidirectional only, as confirmed in the Vishay datasheet. It must be installed with cathode (blue band) toward the protected line and anode to ground. For bidirectional protection, a separate symmetric TVS or back-to-back configuration would be required - neither supported by this part.
What is the maximum clamping voltage of TGL41-47-E3/96 under surge conditions?
The TGL41-47-E3/96 exhibits a maximum clamping voltage (VC) of 64.8 V at its rated peak pulse current (IPPM) of 6.2 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events.
Does TGL41-47-E3/96 meet lead-free reflow requirements?
Yes, TGL41-47-E3/96 is RoHS-compliant (E3 suffix) and qualified to MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 250 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102, enabling compatibility with standard Pb-free reflow profiles without preconditioning.
Can TGL41-47-E3/96 be used in automotive applications?
The TGL41-47-E3/96 is rated for –55 °C to +150 °C junction temperature and meets industrial reliability standards, but Vishay documentation explicitly states that its products are not designed for medical, life-saving, or automotive safety-critical systems unless expressly designated. Use in non-safety automotive subsystems requires customer validation per AEC-Q101.
