Product details
Overview
TGL41-120A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, rated for 126 V breakdown voltage (VBR), 102 V working peak reverse voltage (VWM), and 165 V clamping voltage (VC) at 1.21 A peak pulse current (IPPM). It delivers 400 W peak pulse power (10/1000 μs), supports 40 A surge current (IFSM), and operates from −55 °C to +150 °C - deployed for protecting MOSFETs and sensor signal lines against inductive switching transients in industrial control systems.
For engineers reviewing the TGL41-120A-E3/97 datasheet, TGL41-120A-E3/97 pinout, TGL41-120A-E3/97 application, or TGL41-120A-E3/97 equivalent, key selection criteria include verified clamping performance at 1.21 A, unidirectional polarity with blue-band cathode marking, DO-213AB mechanical compatibility, and RoHS-compliant matte tin-plated terminals meeting J-STD-002 solderability standards.
Technical Context
This TVS diode uses a glass-passivated planar junction structure optimized for fast response (<1 ns) and low incremental surge resistance, enabling effective suppression of sub-microsecond transients induced by relay or solenoid switching. Its unidirectional configuration provides forward conduction capability while clamping reverse overvoltage events above VWM.
The device adheres to ANSI/IEEE C62.35 surge waveform definitions and is rated per 10/1000 μs standard test conditions. Thermal derating follows Fig. 2 in the datasheet, with maximum power dissipation reduced linearly above 25 °C ambient, and junction temperature limited to 150 °C under continuous operation.
Key Specifications

|---|---|
| VBR (min/max) | 114 V / 126 V - ensures reliable triggering above system operating voltage while maintaining margin against false clamping |
| VWM | 102 V - maximum continuous reverse voltage before leakage exceeds 5 μA, defining safe operating ceiling |
| VC @ IPPM | 165 V at 1.21 A - clamped voltage during 10/1000 μs transient, directly limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling capacity, sufficient for industrial-level inductive load surges |
| IFSM | 40 A - 8.3 ms half-sine surge rating, supporting high-energy fault events without bond wire failure |
| TJ max. | +150 °C - enables use in high-temperature environments such as motor drive enclosures or power supply heatsinks |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with solderable ends, compatible with automated placement and reflow |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with two solderable axial terminals. Polarity is marked by a blue band indicating the cathode (positive terminal under normal TVS operation). No internal pins - device functions as a two-terminal bidirectional clamp in unidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased clamping | Connected to ground or low-impedance return path; defines reference for VWM and VC thresholds |
| Cathode (blue band) | Clamping output node | Connected to protected line (e.g., sensor VOUT); conducts during overvoltage to shunt energy to anode |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA120A-E3/97 | Same VWM (102 V) and VC (165 V), but SMA package (DO-214AC), 1.0 W PD, lower IPPM (1.15 A) | Surface-mount flat lead package requires different PCB footprint; lower surge current rating limits use in high-energy industrial settings | Select when board space constraints favor SMC/SMA layout or when 1.15 A IPPM suffices for consumer-grade protection |
| SMBJ120A | DO-214AA package, identical VWM/VC, but 600 W PPPM, higher IPPM (1.8 A), 2.0 W PD | Larger body improves thermal dissipation in high-duty-cycle applications; not MELF-compatible for automated placement | Choose for enhanced surge margin in automotive power distribution units where footprint flexibility exists |
Compared with P4SMA120A-E3/97 and SMBJ120A, the TGL41-120A-E3/97 offers superior placement compatibility in high-speed MELF pick-and-place lines, tighter VBR tolerance (±5 % vs ±10 %), and validated performance in legacy industrial designs - making it preferred where DO-213AB form factor and proven field reliability are mandatory.

FAQ
What is the breakdown voltage range for TGL41-120A-E3/97?
The TGL41-120A-E3/97 has a guaranteed breakdown voltage (VBR) range of 114 V to 126 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This ±5 % tolerance ensures predictable triggering behavior across manufacturing lots and temperature extremes, critical for repeatable protection in safety-critical industrial controls where overvoltage thresholds must remain stable from −55 °C to +125 °C ambient.
Does TGL41-120A-E3/97 support bidirectional transient suppression?
No, the TGL41-120A-E3/97 is unidirectional only, as explicitly stated in the Vishay datasheet. It clamps reverse overvoltage events above VWM = 102 V while permitting forward conduction - making it unsuitable for AC line protection or bipolar signal paths. For bidirectional applications, engineers must select a dedicated bidirectional variant or pair two unidirectional devices; the TGL41-120A-E3/97 itself does not provide symmetrical clamping.
What is the maximum clamping voltage of TGL41-120A-E3/97 under surge conditions?
The TGL41-120A-E3/97 exhibits a maximum clamping voltage (VC) of 165 V at 1.21 A peak pulse current (IPPM) using the standardized 10/1000 μs waveform. This value is measured per Figure 3 in Document Number 88403 and defines the upper voltage limit imposed on protected circuitry during transient events - essential for verifying that downstream components like microcontrollers or gate drivers remain within absolute maximum ratings.
Is TGL41-120A-E3/97 RoHS compliant and qualified for lead-free reflow?
Yes, the TGL41-120A-E3/97 carries the "E3" suffix, confirming RoHS compliance and qualification for lead-free reflow per J-STD-020 MSL Level 1, with a maximum peak reflow temperature of 250 °C. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the GL41 package is rated for single-pass reflow without popcorn cracking - verified in Vishay's reliability testing for high-volume manufacturing environments.
Why is TGL41-120A-E3/97 marked as "Not For New Designs"?
The "Not For New Designs" designation for TGL41-120A-E3/97 reflects Vishay's product lifecycle policy, indicating prioritized support for newer platforms like the P4SMA series. However, the TGL41-120A-E3/97 remains fully manufactured, stocked, and supported for existing designs - with no announced discontinuance. Aetrix Electronics maintains active inventory and long-term supply agreements to ensure continuity for legacy industrial and telecom systems still relying on its DO-213AB form factor and proven field performance.
