Product details
Overview
TGL41-51A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 48.5–53.6 V breakdown voltage, and 70.1 V clamping voltage at 5.7 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-51A-E3/96 datasheet, TGL41-51A-E3/96 pinout, TGL41-51A-E3/96 application, or TGL41-51A-E3/96 equivalent, key selection criteria include unidirectional polarity, 43.6 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 chip junction to achieve fast response time 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 delivers stable clamping performance under repetitive 0.01% duty cycle surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 48.5 V / 53.6 V - ensures reliable turn-on above 43.6 V operating voltage while avoiding false triggering |
| VWM | 43.6 V - maximum continuous reverse working voltage before significant leakage begins |
| VC @ IPPM | 70.1 V - clamping voltage seen by protected circuit during 5.7 A transient, limiting stress on downstream components |
| PPPM | 400 W - peak pulse power handling with 10/1000 μs waveform, sufficient for IEC 61000-4-5 Level 4 surges |
| IFSM | 40 A - 8.3 ms half-sine surge current rating, supporting robust inrush and fault-current tolerance |
| TJ max | +150 °C - enables operation in high-temperature industrial environments without derating penalties |
| Polarity | Unidirectional - requires correct orientation relative to DC bias; cathode marked by blue band |
Pinout & Package

Use Value: 70.1 V clamping voltage preserves signal integrity while protecting op-amp front-ends rated for ±36 V supply rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA51A-E3/96 | Same 51 V nominal breakdown, but SMA package (DO-214AC); 400 W rating; 70 V clamping; 5.0 μA leakage | Surface-mount flat lead package requires different PCB footprint and thermal relief design | Preferred where board space is constrained and automated reflow compatibility with gull-wing leads is required |
| SMBJ51A | DO-214AA package; same 51 V VBR; 600 W PPPM; 81.5 V VC; 10 μA leakage at VWM | Higher clamping voltage reduces protection margin; larger package increases board area usage | Consider only when higher surge energy handling is needed and clamping voltage margin permits |
Compared with P4SMA51A-E3/96 and SMBJ51A, the TGL41-51A-E3/96 offers identical electrical protection specs in a compact MELF form factor optimized for high-reliability industrial placement, with lower leakage and tighter VBR tolerance than SMBJ51A, but requires DO-213AB-compatible layout.

FAQ
What is the standoff voltage rating of the TGL41-51A-E3/96?
The TGL41-51A-E3/96 has a maximum reverse standoff voltage (VWM) of 43.6 V. This means it remains in high-impedance state below that voltage, allowing normal circuit operation while blocking less than 5.0 μA leakage current. Exceeding 43.6 V initiates avalanche breakdown, enabling clamping action to protect downstream components.
Does the TGL41-51A-E3/96 support lead-free reflow assembly?
Yes, the TGL41-51A-E3/96 is RoHS-compliant (E3 suffix) and qualified for lead-free reflow with a maximum peak temperature of 250 °C. It meets MSL Level 1 per J-STD-020, meaning it can be assembled without moisture sensitivity precautions or baking prior to reflow.
What is the clamping voltage of the TGL41-51A-E3/96 under surge conditions?
The TGL41-51A-E3/96 clamps to a maximum of 70.1 V when subjected to its rated peak pulse current of 5.7 A (10/1000 μs waveform). This clamping voltage defines the upper voltage limit imposed on the protected circuit during transient events, ensuring sensitive components remain within safe operating limits.
Is the TGL41-51A-E3/96 suitable for bidirectional transient protection?
No, the TGL41-51A-E3/96 is unidirectional only. Its blue band marks the cathode, and it conducts only when the cathode is positive relative to the anode. For bidirectional protection, a separate device such as a symmetric TVS or back-to-back configuration would be required - the TGL41-51A-E3/96 does not provide reverse conduction capability.
What package type does the TGL41-51A-E3/96 use, and how is polarity indicated?
The TGL41-51A-E3/96 uses the GL41 (DO-213AB) plastic MELF package - a cylindrical surface-mount format with solderable ends. Polarity is indicated by a blue band, which identifies the cathode terminal. During TVS operation, the cathode must be connected to the higher-potential side of the protected line.
