Product details
Overview
TGL41-36A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, featuring 34.2 V minimum breakdown voltage, 37.8 V maximum breakdown voltage at 1.0 mA test current, and 49.9 V maximum clamping voltage at 8.0 A peak pulse current. It delivers 400 W peak pulse power (10/1000 μs), operates from –55 °C to +150 °C, and protects signal lines in industrial sensor interfaces.
For engineers reviewing the TGL41-36A-E3/97 datasheet, TGL41-36A-E3/97 pinout, TGL41-36A-E3/97 application, or TGL41-36A-E3/97 equivalent, key selection criteria include unidirectional polarity, 30.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, low incremental surge resistance, and compliance with J-STD-020 MSL Level 1.
Technical Context
This TVS diode uses a glass passivated planar chip junction for stable breakdown characteristics and fast response to transients. Its unidirectional configuration provides forward conduction only during overvoltage events on the cathode-side line, with clamping action defined by the 10/1000 μs waveform standard per ANSI/IEEE C62.35.
The GL41 package enables automated placement and meets UL 94 V-0 flammability rating; blue band denotes cathode. Thermal performance is rated for TJ up to 150 °C, with power derating above TA = 25 °C per published curves, and solderability validated per J-STD-002 and JESD 22-B102.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 34.2 V min / 37.8 V max at IT = 1.0 mA - defines precise voltage threshold for avalanche conduction |
| Stand-off Voltage VWM | 30.8 V - maximum continuous reverse voltage before significant leakage begins |
| Clamping Voltage VC | 49.9 V at IPPM = 8.0 A - limits transient voltage seen by protected IC or MOSFET |
| Peak Pulse Power PPPM | 400 W (10/1000 μs) - sustains high-energy surges without failure under specified duty cycle |
| Reverse Leakage ID | 5.0 μA max at VWM - ensures minimal standby power loss and signal integrity in high-impedance paths |
| Operating Temperature | –55 °C to +150 °C - supports deployment in automotive engine bays and industrial control cabinets |
| Package | GL41 (DO-213AB) - compact MELF format optimized for reflow-compatible automated assembly |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is marked by a blue band indicating the cathode (positive terminal under normal TVS operation). No internal leads or pads - device functions as a two-terminal bilateral protection element with defined anode/cathode orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping path during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges without thermal runaway |
| Glass passivated planar junction | Ensures stable VBR tolerance and long-term reliability under repetitive transient stress |
| MSL Level 1 per J-STD-020 | Allows unlimited floor life and single-reflow compatibility without dry-pack requirements |
| Matte tin-plated terminals | Guarantees solder joint integrity and intermetallic formation control per J-STD-002 |
| Unidirectional polarity only | Simplifies layout for DC-biased lines where reverse conduction must be blocked |
Applications
| Industrial Sensor Interface Protection | Telecom Line Card Surge Suppression |
|---|---|

IC Role / Device Role / Timing Role: Cathode tied to LIN line, anode grounded; activates within <1 ns to clamp transients exceeding 30.8 V. Use Value: Maintains VWM margin above 12 V nominal supply while delivering sub-50 V clamping-critical for ISO 16750-2 compliance. | Use Scenario: Protecting microcontroller GPIOs driving relay coils in smart washing machine control boards. IC Role / Device Role / Timing Role: Placed across coil terminals to suppress flyback voltage spikes generated during de-energization. Use Value: Handles 40 A peak forward surge (IFSM), ensuring no failure during repeated motor start-stop cycles over 10-year product lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA36A-E3/97 | Same VBR (34.2–37.8 V), same DO-214AC (SMA) package, 400 W PPPM, but higher VF (3.5 V) and larger footprint than GL41 | Requires PCB layout change due to SMA vs. MELF form factor; better suited for manual repair or lower-density boards | Select when board space allows larger package and hand-soldering is acceptable |
| SMAJ36A-E3/52T | Identical electrical specs (VBR, VC, PPPM), DO-214AC package, AEC-Q200 qualified, but not MELF | Qualified for automotive use per AEC-Q200; unsuitable for space-constrained MELF-only footprints | Choose for automotive production requiring qualification evidence and larger pad geometry |
Compared with TGL41-36A-E3/97, P4SMA36A-E3/97 offers identical clamping performance but demands more PCB area and lacks MELF's automated placement advantage; SMAJ36A-E3/52T adds automotive qualification at the cost of footprint compatibility and MELF-specific thermal profile optimization.

FAQ
What is the clamping voltage of the TGL41-36A-E3/97 under a 10/1000 μs surge?
The TGL41-36A-E3/97 has a maximum clamping voltage VC of 49.9 V at 8.0 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events. The TGL41-36A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-36A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-36A-E3/97 as "Not For New Designs" in its official documentation (Document Number: 88403, Revision: 14-Nov-2023). Engineers developing new products should consider approved alternatives such as the P4SMA36A-E3 series. The TGL41-36A-E3/97 remains supported for existing production and legacy BOM continuity.
What does the "E3/97" suffix indicate in TGL41-36A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 22-B102 whisker resistance (Class 1A). The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units - distinct from the /96 variant (7-inch reel, 1500 units).
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-36A-E3/97?
The GL41 package provides low thermal resistance from junction to ambient in reflow-soldered applications, supporting 1.0 W steady-state power dissipation at TL = 75 °C on an infinite heatsink. Its cylindrical MELF geometry enables uniform heating during reflow and efficient heat spreading through end terminations - critical for sustaining repetitive surge duty cycles without thermal runaway. The TGL41-36A-E3/97 leverages this for reliable operation up to TJ = 150 °C.
Can the TGL41-36A-E3/97 be used in bidirectional configurations?
No - the TGL41-36A-E3/97 is specified for unidirectional polarity only, with cathode marked by a blue band. It conducts only when the cathode is positive relative to the anode. For bidirectional protection, two TGL41-36A-E3/97 devices must be connected in series opposition, or a dedicated bidirectional TVS (e.g., TGL41-36CA) should be selected. The TGL41-36A-E3/97 datasheet explicitly states "Available in unidirectional polarity only."
