Product details
Overview
TGL41-11A-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), 10.5–11.6 V breakdown voltage, and 15.6 V clamping voltage at 25.6 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-11A-E3/96 datasheet, TGL41-11A-E3/96 pinout, TGL41-11A-E3/96 application, or TGL41-11A-E3/96 equivalent, key selection criteria include unidirectional polarity, 9.4 V stand-off voltage, 5.0 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 to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction capability with 3.5 V max instantaneous forward voltage at 25 A, enabling protection of DC-biased signal lines and power rails.
The device operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. Its DO-213AB package supports automated placement and complies with UL 94 V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 10.5 V / 11.6 V - ensures reliable triggering above 9.4 V operating voltage without false clamping |
| VWM | 9.4 V - maximum continuous reverse working voltage before breakdown initiation |
| VC @ IPPM | 15.6 V - clamping voltage during 25.6 A transient, limiting downstream voltage stress |
| PPPM | 400 W - peak pulse power handling for 10/1000 μs waveform, sufficient for IEC 61000-4-5 Level 3 surges |
| IPPM | 25.6 A - peak pulse current capacity derived from 400 W / 15.6 V, defining surge energy limit |
| IR @ VWM | 5.0 μA - ultra-low reverse leakage preserves signal integrity in high-impedance sensor interfaces |
| TJ max | +150 °C - enables use in thermally constrained industrial motor drives and power converters |
Pinout & Package
GL41 (DO-213AB) plastic MELF package with axial leads: cathode denoted by blue band; anode and cathode terminals are non-polarized in layout but functionally asymmetric-cathode is positive relative to anode under normal TVS operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to circuit ground or low-side return path; defines directionality of transient shunting |

| MSL Level 1 rating | Allows single-reflow assembly without moisture sensitivity concerns, reducing manufacturing risk |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial equipment and power supplies |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and eliminates whisker growth per JESD 201 Class 1A |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and feedback sensing circuits from inductive kickback during IGBT switching in variable-frequency drives. IC Role / Device Role / Timing Role: Unidirectional TVS clamps transient spikes on 12 V bias rails and isolated current-sense lines. Use Value: Limits voltage excursion to ≤15.6 V during 25.6 A surges, preventing latch-up or gate oxide damage in SiC MOSFET drivers. | Use Scenario: Input-stage surge suppression on -48 V DC telecom rectifier outputs exposed to lightning-induced common-mode transients. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbs 400 W pulses while maintaining <5 μA leakage at nominal -48 V system voltage. Use Value: Enables compliance with GR-1089-CORE Level 3 (2 kV/12 Ω) without derating due to its 9.4 V VWM margin over system operating range. |
| Automotive Body Control Modules | Consumer Appliance Power Boards |
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and jump-start transients in 12 V vehicle subsystems. IC Role / Device Role / Timing Role: Fast-response TVS placed at connector entry point to clamp sub-100 ns spikes before reaching sensitive analog front-ends. Use Value: Sub-ns response time and 15.6 V clamping prevent false resets and ADC corruption during ISO 7637-2 Pulse 5a events. | Use Scenario: Secondary-side overvoltage suppression on 5 V/3.3 V SMPS outputs feeding microcontrollers and touch sensors in washing machines and HVAC controllers. IC Role / Device Role / Timing Role: Low-leakage (5 μA) unidirectional suppressor maintains regulation accuracy while absorbing ESD and relay bounce energy. Use Value: Prevents brownout resets and firmware lockups caused by 100–200 V transients induced by compressor motor commutation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA11A-E3/96 | Same 11 V nominal breakdown, but SMA package (DO-214AC); 400 W rating; 16.5 V clamping at 24.6 A | Surface-mount flat lead vs. MELF cylindrical; requires different land pattern and reflow profile | Select when board space constraints favor SMD over axial MELF, and thermal mass allows lower surge current margin |
| SMAJ11A | DO-214AC package; 400 W rating; 16.0 V clamping at 25.0 A; higher leakage (10 μA @ VWM) | Higher reverse leakage may affect precision sensor bias networks; identical surge rating | Prefer for cost-sensitive consumer designs where 10 μA leakage is acceptable and MELF placement infrastructure is unavailable |
Compared with P4SMA11A-E3/96 and SMAJ11A, the TGL41-11A-E3/96 offers superior thermal cycling reliability in axial MELF form factor, lower leakage for high-impedance nodes, and tighter VBR tolerance-making it optimal for industrial and telecom systems requiring long-term surge endurance.

FAQ
What is the clamping voltage of the TGL41-11A-E3/96 under maximum rated surge current?
The TGL41-11A-E3/96 has a maximum clamping voltage (VC) of 15.6 V at its rated peak pulse current (IPPM) of 25.6 A, measured with a 10/1000 μs waveform. This value ensures downstream components see no more than 15.6 V during worst-case transient events, directly supporting design margin calculations for 12 V rail protection in the TGL41-11A-E3/96 application space.
Is the TGL41-11A-E3/96 suitable for bidirectional transient protection?
No, the TGL41-11A-E3/96 is unidirectional only, with polarity marked by a blue band indicating the cathode. It conducts in forward bias like a standard diode and clamps reverse transients only. For bidirectional protection, a separate symmetric TVS such as the SMBJ11CA would be required-not the TGL41-11A-E3/96.
What does the "E3/96" suffix indicate in TGL41-11A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads qualified per JESD 201 Class 1A whisker testing. The "/96" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units-standard for automated SMT placement of the TGL41-11A-E3/96.
Can the TGL41-11A-E3/96 replace the TGL41-10A in an existing design?
Yes, the TGL41-11A-E3/96 can replace TGL41-10A if the 9.4 V stand-off voltage meets system requirements (vs. TGL41-10A's 8.55 V), and the slightly higher clamping voltage (15.6 V vs. 14.5 V) remains within downstream IC tolerances. Both share identical GL41 package, thermal specs, and surge ratings-making the TGL41-11A-E3/96 a direct functional upgrade where tighter VBR control is needed.
What is the maximum operating temperature for the TGL41-11A-E3/96 junction?
The TGL41-11A-E3/96 has a maximum junction temperature (TJ) of +150 °C, validated per JEDEC standards. This allows continuous operation in high-ambient environments such as enclosed power converters or under-hood automotive modules, provided PCB copper area and airflow maintain junction temperature below 150 °C during both steady-state and transient conditions for the TGL41-11A-E3/96.
