Product details
Overview
TGL41-18A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 17.1 V minimum breakdown voltage, 15.3 V standoff voltage, and 400 W peak pulse power (10/1000 μs), designed to protect MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-18A-E3/96 datasheet, TGL41-18A-E3/96 pinout, TGL41-18A-E3/96 application, or TGL41-18A-E3/96 equivalent, key selection criteria include clamping voltage (25.2 V at 15.9 A), low incremental surge resistance, unidirectional polarity with blue-band cathode marking, and MSL Level 1 moisture sensitivity rating for automated SMT placement.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<5 μA leakage at 15.3 V), then rapidly avalanches when transient voltage exceeds 17.1 V (min) to clamp the line at ≤25.2 V. Its glass-passivated junction ensures stable breakdown and fast response time.
The device is rated for 400 W peak pulse power only below 91 V; above that threshold, derating applies per Fig. 2, and maximum continuous power dissipation is 1.0 W on infinite heatsink at 75 °C. It supports 40 A non-repetitive forward surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - defines precise avalanche initiation range for reliable overvoltage triggering |
| VWM | 15.3 V - maximum working voltage before leakage exceeds 5 μA; sets safe operating margin below VBR |
| VC @ IPPM | 25.2 V @ 15.9 A - clamping voltage during 10/1000 μs transient; determines protected circuit's peak stress level |
| PPPM | 400 W - peak pulse power handling capability for standard lightning/inductive surge waveforms |
| IFSM | 40 A - surge current tolerance for 8.3 ms half-sine waveform; critical for motor driver or relay coil snubbing |
| TJ max | +150 °C - maximum junction temperature; enables operation in high-ambient industrial environments |
| Package | GL41 (DO-213AB) - MELF-style surface-mount package optimized for automated placement and thermal reliability |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is marked by a blue band denoting the cathode (positive terminal under reverse-bias TVS operation). No internal leads or pins - terminals are metallized ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-bias protection | Connected to ground or low-impedance return path; carries full surge current during clamping |
| Cathode (blue band end) | Protected line connection | Connected to signal/power line being safeguarded; voltage referenced to anode during transient event |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF construction | Enables high-volume automated placement and consistent thermal performance vs. axial-leaded alternatives |
| Glass-passivated junction | Ensures stable VBR tolerance (±5 %), low leakage, and long-term reliability under repeated surges |
| MSL Level 1 rating | Permits reflow soldering without pre-bake; compatible with standard SMT assembly processes up to 250 °C peak |
| Unidirectional polarity only | Optimized for DC-biased lines (e.g., power rails, gate drivers); eliminates ambiguity in cathode orientation |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for downstream ICs |
Applications
| Industrial Motor Control | Automotive Sensor Interface |
|---|---|
Use Scenario: Protection of MOSFET gate drivers and IGBTs against voltage spikes from relay coil de-energization or inductive load switching in PLC output modules. IC Role / Device Role / Timing Role: Shunt TVS device placed across gate-source or collector-emitter to clamp transients before they exceed MOSFET VGS or VCE ratings. Use Value: Clamps to 25.2 V at 15.9 A, preventing gate oxide damage and ensuring >2.1 V safety margin below typical 27 V automotive supply transients. | Use Scenario: Safeguarding analog signal lines (e.g., 0–5 V throttle position sensor outputs) from ESD and load-dump-induced surges in engine control units. IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and chassis ground to suppress sub-100 ns ESD events and slower 10/1000 μs load-dump pulses. Use Value: 15.3 V standoff allows full sensor dynamic range while 25.2 V clamping prevents ADC input saturation or op-amp rail-to-rail latch-up. |
| Telecom Power Supply Input | Consumer Appliance Microcontroller I/O |
Use Scenario: Secondary-side transient suppression on +12 V or +24 V DC-DC converter outputs feeding baseband processors in telecom infrastructure equipment. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after filtering stage to absorb residual surges escaping primary-side protection. Use Value: 400 W peak pulse rating handles repetitive 10/1000 μs surges from nearby lightning strikes without degradation; MELF package withstands thermal cycling in fanless enclosures. | Use Scenario: I/O line protection on microcontroller GPIOs driving relays or reading push-button inputs in smart home appliances subject to user-handling ESD. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on each I/O trace to divert ESD current away from MCU ESD structures. Use Value: 5 μA leakage at 15.3 V avoids loading weak pull-up networks; blue-band polarity ensures correct orientation during manual PCB inspection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA18A-E3/96 | Same VWM (15.3 V) and VC (25.2 V), but lower PPPM (400 W → 400 W), DO-41 package (axial, larger footprint) | Requires through-hole mounting; less suitable for high-density SMT layouts or automated assembly | Select when board space permits axial components and legacy DO-41 tooling is in use |
| SMAJ18A-E3/52T | Same electrical specs, but SMA package (flat lead, smaller than GL41), higher thermal resistance (RθJA ≈ 100 °C/W vs. ~75 °C/W for GL41) | Better suited for low-power consumer boards; less robust under sustained surge duty cycles | Select for cost-sensitive, low-surge-frequency applications where GL41's MELF ruggedness is not required |
Compared with P4SMA18A-E3/96 and SMAJ18A-E3/52T, the TGL41-18A-E3/96 offers superior thermal performance in compact MELF form factor, tighter VBR tolerance, and MSL Level 1 compatibility-making it preferred for high-reliability industrial SMT designs requiring repeatable surge immunity.

FAQ
What is the exact breakdown voltage range for TGL41-18A-E3/96?
The TGL41-18A-E3/96 has a guaranteed breakdown voltage range of 17.1 V (minimum) to 18.9 V (maximum) at 1.0 mA test current, as specified in the Vishay datasheet document 88403. This tight ±5 % tolerance ensures predictable clamping onset across production lots and temperature extremes.
Is TGL41-18A-E3/96 suitable for bidirectional transient protection?
No, the TGL41-18A-E3/96 is unidirectional only, with polarity indicated by a blue band marking the cathode. It must be installed with the blue band toward the protected line and the opposite end grounded. For bidirectional protection, a separate symmetric TVS or dual-diode configuration is required.
What does the "E3/96" suffix mean in TGL41-18A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "/96" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel.
How does TGL41-18A-E3/96 perform under elevated ambient temperatures?
The TGL41-18A-E3/96 derates linearly above 25 °C ambient: its peak pulse power drops per Figure 2 in the datasheet, and maximum junction temperature remains limited to +150 °C. At 75 °C ambient, its continuous power dissipation is reduced to 1.0 W only when mounted on an infinite heatsink.
Why is TGL41-18A-E3/96 marked as "Not For New Designs"?
Vishay designates TGL41-18A-E3/96 as "Not For New Designs" because newer platforms like the P4SMA and SMAJ families offer improved surge robustness, tighter tolerances, and broader voltage coverage. However, TGL41-18A-E3/96 remains fully supported for existing designs and legacy production with no announced obsolescence date.
