Product details
Overview
TGL41-13A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, designed for clamping voltage transients on signal and power lines. It features 12.4 V to 13.7 V breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 18.2 V clamping voltage (VC) at 22.0 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs and ICs in industrial sensor interfaces.
For engineers reviewing the TGL41-13A-E3/97 datasheet, TGL41-13A-E3/97 pinout, TGL41-13A-E3/97 application, or TGL41-13A-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 1.0 W steady-state power dissipation, -55 °C to +150 °C operating junction temperature, and blue-band cathode identification for PCB layout and ESD-sensitive circuit protection.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below VWM = 11.1 V and rapidly avalanches above VBR (min 12.4 V) to limit transient overvoltage. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5.0 µA at VWM), while the MELF package supports automated placement and meets J-STD-020 MSL Level 1.
The device delivers 400 W peak pulse power (10/1000 µs) up to 91 V; above that threshold, derating applies per Fig. 2, and maximum clamping occurs at 18.2 V under 22.0 A IPPM. Its 0.084 %/°C VBR temperature coefficient enables predictable performance across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - defines minimum avalanche initiation and maximum variation at 1.0 mA test current |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 5.0 µA |
| VC @ IPPM | 18.2 V at 22.0 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 400 W - peak transient energy absorption capability under standard waveform |
| TJ range | -55 °C to +150 °C - operational junction temperature window for embedded and industrial environments |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with matte tin-plated leads, RoHS-compliant E3 suffix |
| Polarity | Unidirectional - cathode marked by blue band; conducts only in reverse avalanche mode |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with two solderable axial terminals. The blue band identifies the cathode (positive terminal under reverse bias). No internal pins; terminals are symmetric and non-polarized except for marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail; carries surge return current |
| Cathode (blue band) | Clamping node | Connected to protected line; avalanches to clamp transients toward anode when V > VBR |
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 junction | Ensures stable VBR tolerance and long-term reliability under repetitive transient stress |
| MSL Level 1 (250 °C peak reflow) | Supports lead-free SMT assembly without preconditioning or special handling |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (e.g., inductive switch-off) |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed industrial and telecom equipment |
Applications
| Industrial Sensor Interface Protection | Automated Test Equipment (ATE) Signal Line Clamping |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to relay coil flyback in factory automation cabinets. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between sensor output and microcontroller ADC input. Use Value: Limits induced transients to ≤18.2 V, preventing ADC saturation and latch-up in 3.3 V or 5 V systems. | Use Scenario: Shielding digital control lines (e.g., SPI clock/data) in ATE fixtures from ESD and relay-induced spikes during board-level functional testing. IC Role / Device Role / Timing Role: Fast-response transient suppressor mounted directly at connector entry point on fixture PCB. Use Value: Sub-1 ns response time and 18.2 V clamping preserve signal integrity and prevent false triggering in high-speed digital lines. |
| Telecom Power Supply Input Protection | MOSFET Gate Driver Transient Suppression |
Use Scenario: Safeguarding DC-DC converter inputs in PoE-powered network switches against lightning-induced surges on 48 V supply rails. IC Role / Device Role / Timing Role: Primary-stage TVS on secondary-side 48 V bus, upstream of filtering and regulation. Use Value: 400 W rating handles multi-pulse surges; 11.1 V VWM allows use on 12 V auxiliary rails without leakage issues. | Use Scenario: Preventing gate oxide damage in high-side N-channel MOSFET drivers subjected to Miller-induced voltage spikes during switching transitions. IC Role / Device Role / Timing Role: Clamp diode connected between gate and source, referenced to driver IC ground. Use Value: Low clamping voltage (18.2 V) ensures gate voltage stays within safe SOA limits even during 22 A transient events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA13A-E3/97 | Same VBR range (12.4–13.7 V), but SMA package (DO-214AC); 400 W rating; higher capacitance (~50 pF vs. ~20 pF for TGL41) | Suitable for PCBs with surface-mount pad layouts instead of MELF-compatible footprints; less ideal for high-frequency signal lines due to higher junction capacitance | Select P4SMA13A-E3/97 when board space constraints favor flat SMD over cylindrical MELF, and RF sensitivity is not critical. |
| SMAJ13A | DO-214AC package; identical VBR/VC specs; 400 W rating; JEDEC-standardized footprint; no E3 whisker test compliance | Preferred where legacy SMA/SMAJ footprint reuse is required; lacks JESD 201 Class 1A whisker resistance for high-reliability automotive or aerospace programs | Choose SMAJ13A for cost-sensitive industrial designs where whisker risk is mitigated by process controls, not component-level qualification. |
Compared with P4SMA13A-E3/97 and SMAJ13A, the TGL41-13A-E3/97 offers superior high-frequency performance due to lower junction capacitance and tighter VBR tolerance, while its MELF form factor provides higher power density per unit volume and better thermal cycling reliability in harsh environments.

FAQ
What is the breakdown voltage range for TGL41-13A-E3/97?
The TGL41-13A-E3/97 has a guaranteed breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design in 12 V systems.
Is TGL41-13A-E3/97 suitable for bidirectional transient protection?
No, the TGL41-13A-E3/97 is unidirectional only, with cathode identified by a blue band. It conducts only during reverse-bias avalanche and must be oriented correctly in-circuit. For bidirectional protection, a separate symmetrical TVS or back-to-back configuration would be required - neither is supported by the TGL41-13A-E3/97 itself.
What does the "/97" suffix indicate in TGL41-13A-E3/97?
The "/97" suffix denotes the preferred package code for 13-inch diameter plastic tape and reel delivery, containing 5000 units per reel. This differs from "/96", which specifies 7-inch reels of 1500 units. Both share identical electrical and mechanical specifications, including the E3 RoHS-compliant, whisker-tested finish.
How does the GL41 (DO-213AB) package affect thermal performance of TGL41-13A-E3/97?
The GL41 (DO-213AB) MELF package provides higher surface-area-to-volume ratio than flat SMD packages, enabling more efficient convective cooling. With a 1.0 W steady-state power dissipation rating and MSL Level 1 reflow compatibility, the TGL41-13A-E3/97 maintains stable junction temperature under continuous leakage conditions in sealed enclosures.
Why is TGL41-13A-E3/97 marked as "Not For New Designs"?
Vishay designates TGL41-13A-E3/97 as "Not For New Designs" because newer platforms (e.g., P4SMA series) offer improved manufacturability, broader voltage coverage, and enhanced supply chain scalability. However, TGL41-13A-E3/97 remains fully supported for existing designs, with active production, full datasheet documentation, and long-term availability through authorized channels like Aetrix Electronics.
