Product details
Overview
TGL41-56A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 53.2 V minimum breakdown voltage, 47.8 V standoff voltage, and 77.0 V maximum clamping voltage at 5.2 A peak pulse current. It delivers 400 W peak pulse power (10/1000 μs), operates from –55 °C to +150 °C, and protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-56A-E3/96 datasheet, TGL41-56A-E3/96 pinout, TGL41-56A-E3/96 application, or TGL41-56A-E3/96 equivalent, this page provides verified electrical parameters, mechanical package data, clamping behavior under surge, thermal derating curves, and validated alternative options for legacy design support and obsolescence mitigation.
Technical Context
The TGL41-56A-E3/96 uses a glass-passivated planar junction structure optimized for fast response (<1 ns) and low incremental surge resistance. Its unidirectional polarity-marked by a blue cathode band-enables integration into DC-biased signal or power rails where reverse conduction must be blocked during normal operation.
Rated for 400 W peak pulse power (10/1000 μs) and 1.0 W steady-state power dissipation on infinite heatsink, it supports repetitive transient suppression up to 0.01% duty cycle. Junction temperature is rated to 150 °C, with derating beginning above 25 °C ambient per Figure 2 of document 88403.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 53.2 V / 58.8 V - defines reliable avalanche initiation range under 1.0 mA test current; ensures consistent clamping onset across production lots |
| VWM | 47.8 V - maximum continuous reverse working voltage; sets safe DC operating margin below breakdown |
| VC @ IPPM | 77.0 V at 5.2 A - clamped voltage during 10/1000 μs surge; determines protected circuit's maximum transient overvoltage exposure |
| PPPM | 400 W - peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges in industrial environments |
| IFSM | 40 A - 8.3 ms half-sine surge rating; supports protection of downstream rectifiers and switching FETs during AC line faults |
| TJ Range | –55 °C to +150 °C - extended junction temperature range enables use in under-hood automotive modules and high-temperature industrial controls |
| Package | GL41 (DO-213AB) - MELF-style cylindrical package with matte tin-plated leads; compatible with automated placement and meets J-STD-002 solderability |
Pinout & Package
GL41 (DO-213AB) is a two-terminal axial plastic MELF package with cathode identified by a blue band. Terminals are non-polarized in layout but functionally asymmetric: the banded end is cathode (positive during TVS conduction), the unbanded end is anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink during overvoltage | Connected to protected line; conducts avalanche current to ground or lower-potential rail when VLINE exceeds VBR |
| Anode | Reference terminal / return path | Typically tied to system ground or common return; completes surge current path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated planar junction | Enables stable, low-leakage performance (≤5 μA at VWM) and long-term reliability under thermal cycling |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 combination wave testing up to 4 kV open-circuit / 2 kA short-circuit without degradation |
| MSL Level 1 (J-STD-020) | Allows unlimited floor life and reflow compatibility up to 250 °C peak, eliminating bake requirements before SMT assembly |
| Unidirectional polarity only | Prevents unintended forward conduction in DC-biased applications; eliminates need for series blocking diodes in power rail protection |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and telecom equipment housings |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|

| Automotive Body Control Modules | Consumer Appliance Power Boards |
Use Scenario: Protection of LIN bus transceivers and microcontroller I/O pins against load dump and ISO 7637-2 Pulse 1/2a transients in 12 V systems. IC Role / Device Role / Timing Role: TVS placed on LIN line input to absorb negative-going transients and limit positive excursions during battery disconnect events. Use Value: Withstands 40 A 8.3 ms surge (IFSM) and clamps to 77.0 V, ensuring transceiver survival during 100 V/50 ms load dump simulations. | Use Scenario: Overvoltage protection on AC-DC converter primary-side snubber networks and secondary-side 5 V/12 V rails in washing machine control boards. IC Role / Device Role / Timing Role: Standoff-rated TVS suppressing ESD and relay-contact bounce transients on microcontroller supply inputs. Use Value: Maintains 47.8 V working voltage margin while delivering 400 W pulse handling-sufficient for EN 61000-4-2 Level 4 (15 kV air) and IEC 61000-4-4 burst immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA56A-E3/96 | Same 56 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 77 V clamping at 5.2 A; higher junction capacitance (150 pF vs. ~50 pF) | Surface-mount flat leaded package requires different PCB footprint and thermal relief; less suitable for high-frequency signal lines due to higher CJ | Select when board space constraints favor SMC/SMA over MELF, and when thermal mass from copper pour can compensate for lower power density. |
| SMBJ56A | DO-214AA package; identical VBR, VWM, VC, and PPPM; rated for 1.0 W PD but larger thermal resistance (RθJA ≈ 100 °C/W vs. ~75 °C/W for GL41) | Bulkier outline increases mounting area; better suited for manual repair or high-reliability through-hole hybrid assemblies | Choose when legacy board designs use SMB footprint or when enhanced mechanical robustness against vibration is required in transportation equipment. |
Compared with P4SMA56A-E3/96 and SMBJ56A, the TGL41-56A-E3/96 offers superior power density in a compact MELF form factor, lower thermal resistance for high-duty-cycle surge environments, and tighter VBR tolerance (±5.5% vs. ±6.5%), making it preferable for space-constrained industrial controllers where thermal management is limited.

FAQ
What is the exact breakdown voltage range for TGL41-56A-E3/96?
The TGL41-56A-E3/96 has a guaranteed breakdown voltage range of 53.2 V to 58.8 V at 1.0 mA test current, per Vishay document 88403, Table on page 2. This range reflects manufacturing tolerance and ensures consistent avalanche turn-on across units without requiring binning for most protection applications.
Is TGL41-56A-E3/96 RoHS compliant and lead-free?
Yes, the TGL41-56A-E3/96 is RoHS compliant and lead-free. The "E3" suffix explicitly denotes compliance with EU RoHS Directive 2011/65/EU and meets JESD 201 Class 1A whisker resistance requirements, as confirmed in the Mechanical Data section of Vishay document 88403.
Does TGL41-56A-E3/96 support bidirectional transient suppression?
No, TGL41-56A-E3/96 is unidirectional only. The blue band marks the cathode, and the device conducts only when the cathode is more positive than the anode. Bidirectional variants are not offered in the TGL41 family; for AC-line protection, two unidirectional devices must be used in series opposition.
What is the maximum clamping voltage of TGL41-56A-E3/96 under surge conditions?
The maximum clamping voltage of TGL41-56A-E3/96 is 77.0 V at 5.2 A peak pulse current (IPPM) with a 10/1000 μs waveform, as specified in the Electrical Characteristics table of Vishay document 88403. This value defines the upper voltage limit imposed on protected circuits during standardized surge events.
Why is TGL41-56A-E3/96 marked "Not For New Designs"?
Vishay designates TGL41-56A-E3/96 as "Not For New Designs" because newer platforms like the P4SMA series offer improved surge robustness, tighter parameter distributions, and broader voltage coverage. However, TGL41-56A-E3/96 remains fully supported for existing designs, with full datasheet documentation, lifetime buy options, and active inventory at authorized distributors including Aetrix Electronics.
