Overview
TGL41-120-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) MELF package, designed for robust overvoltage protection of sensitive electronics. It features 114 V to 126 V breakdown voltage (VBR), 102 V standoff voltage (VWM), 1.21 A peak pulse current (IPPM), and clamps transients to ≤165 V at rated surge - used in industrial sensor signal lines and MOSFET gate protection.
For engineers reviewing the TGL41-120-E3/97 datasheet, TGL41-120-E3/97 pinout, TGL41-120-E3/97 application, or TGL41-120-E3/97 equivalent, key selection criteria include unidirectional polarity, 400 W peak pulse power (10/1000 µs), 1.0 W steady-state power dissipation, -55 °C to +150 °C operating temperature, and RoHS-compliant matte tin-plated terminals.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for clamping fast-rising transients from inductive switching or ESD events.
The DO-213AB (GL41) plastic MELF package supports automated placement and meets UL 94 V-0 flammability rating. Thermal performance is specified up to 150 °C junction temperature, with derating curves provided for operation above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 114 V / 126 V - ensures reliable conduction onset above normal circuit operating voltage while avoiding false triggering |
| VWM | 102 V - maximum continuous reverse voltage the device blocks without significant leakage (≤5 μA) |
| IPPM | 1.21 A - peak transient current it safely clamps under 10/1000 µs waveform, defining surge handling capability |
| VC | ≤165 V - clamped voltage during IPPM, directly limiting stress on downstream ICs or MOSFETs |
| PPPM | 400 W - peak pulse power rating confirming suitability for high-energy transients per industry-standard waveform |
| TJ max | +150 °C - maximum junction temperature enabling use in thermally demanding industrial environments |
| Polarity | Unidirectional - requires correct orientation in series with positive rail; cathode (blue band) faces load side |
Pinout & Package
DO-213AB (GL41) plastic MELF package: cylindrical glass-body construction with solderable matte tin-plated ends; blue band denotes cathode terminal; no leads - terminals are axial end caps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction; connected to system ground or lower-potential node | Must be tied to reference plane; reverse-biased during normal operation; conducts only during negative-going transients if placed across supply rails |
| Cathode (blue band end) | Current exit point during forward conduction; connected to protected line or higher-potential node | Marked terminal defines polarity; connects to signal line or VCC rail being protected; clamps excess voltage to this node during overvoltage events |

Applications
| Industrial Sensor Signal Protection | MOSFET Gate Protection |
|---|---|
Use Scenario: Protecting 4–20 mA current-loop sensor outputs from inductive kickback and ESD in factory automation PLC modules. IC Role / Device Role / Timing Role: TVS diode placed across signal line and ground to clamp transients before they reach ADC input or isolation amplifier. Use Value: Limits induced voltage to ≤165 V, preventing latch-up or damage to 24 V-tolerant signal conditioning ICs while maintaining <5 μA leakage at 102 V. | Use Scenario: Safeguarding N-channel MOSFET gates in DC-DC converter half-bridge drivers exposed to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Unidirectional TVS connected between gate and source to absorb positive-going gate overvoltage without interfering with PWM control timing. Use Value: Clamps gate-source voltage to ≤165 V within nanoseconds, preserving MOSFET safe operating area (SOA) and preventing unintended turn-on. |
| Telecom Line Interface Protection | Computer Peripheral Port Protection |
Use Scenario: Shielding RS-485 transceiver data lines in base station backhaul equipment from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: TVS placed differentially across A/B bus lines to suppress common-mode transients while preserving signal integrity up to 10 Mbps. Use Value: With 102 V standoff, it remains inactive during normal ±7 V differential signaling but activates decisively at >114 V, ensuring protocol compliance and interface longevity. | Use Scenario: Hardening USB 2.0 D+/D− lines in industrial docking stations against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Discrete TVS pair (one per line) referenced to ground, leveraging fast response to divert 8 kV contact discharge energy away from PHY IC. Use Value: Sub-1 ns response and ≤165 V clamping prevent data corruption or PHY latch-up, meeting IEC 61000-4-2 Level 4 requirements without adding capacitance that degrades signal rise time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110A | DO-214AC (SMA) package; 110 V VWM; 1.3 A IPPM; 400 W PPPM; same unidirectional polarity | Surface-mount flat lead vs. MELF cylindrical; higher board footprint but easier manual rework | Select SMAJ110A when PCB layout favors SMA packages or automated optical inspection requires planar terminations |
| P6SMB120A | DO-214AA (SMB) package; 120 V VWM; 1.17 A IPPM; 600 W PPPM; same unidirectional polarity | Higher peak power rating but larger footprint; slightly higher clamping voltage (193 V) | Choose P6SMB120A where surge energy exceeds 400 W limits or thermal mass requirements favor SMB's higher PD (1.5 W) |
Compared with TGL41-120-E3/97, SMAJ110A offers identical surge rating in a more serviceable package but with reduced thermal efficiency, while P6SMB120A delivers higher pulse energy margin at the cost of larger size and elevated clamping - making TGL41-120-E3/97 optimal for space-constrained, high-density MELF-optimized designs requiring precise 102 V standoff.

FAQ
What is the polarity configuration of the TGL41-120-E3/97?
The TGL41-120-E3/97 is a unidirectional TVS diode with cathode identified by a blue band on the package. During normal operation, it blocks reverse voltage up to 102 V (VWM) and conducts only when the cathode is at a higher potential than the anode - essential for proper placement across supply rails or signal-to-ground paths. This polarity must be observed to ensure effective clamping.
Does the TGL41-120-E3/97 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-120-E3/97 carries the "E3" suffix indicating full RoHS compliance per Directive 2011/65/EU and passes JESD201 Class 1A whisker testing. Its matte tin-plated terminals are solderable per J-STD-002 and JESD22-B102, supporting lead-free reflow profiles with peak temperatures up to 250 °C (MSL Level 1).
What is the maximum clamping voltage for the TGL41-120-E3/97 under rated surge conditions?
The TGL41-120-E3/97 has a maximum clamping voltage (VC) of 165 V when subjected to its rated peak pulse current of 1.21 A (IPPM) using the standard 10/1000 µs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
Can the TGL41-120-E3/97 be used in bidirectional protection applications?
No, the TGL41-120-E3/97 is strictly unidirectional and not rated for bidirectional operation. For symmetrical AC or dual-polarity transient protection, a dedicated bidirectional TVS (e.g., TGL41-120CA) or back-to-back unidirectional configuration would be required - using TGL41-120-E3/97 in reverse bias beyond VWM risks irreversible breakdown.
What is the junction temperature range and thermal derating behavior of the TGL41-120-E3/97?
The TGL41-120-E3/97 operates from -55 °C to +150 °C junction temperature. Its 400 W peak pulse power and 1.0 W steady-state power dissipation are specified at 25 °C ambient; both ratings decrease linearly above 25 °C per the derating curve in Figure 2 of Vishay document 88403, reaching zero at 150 °C junction temperature.
