Product details
Overview
TGL41-12-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for surge protection on signal and power lines. It features 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), 16.7 V clamping voltage at 24.0 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 TGL41-12-E3/97 datasheet, TGL41-12-E3/97 pinout, TGL41-12-E3/97 application, or TGL41-12-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, 10.2 V working voltage margin, 16.7 V clamping performance under 24 A surge, and RoHS-compliant matte tin-plated terminals meeting JESD 201 class 1A whisker test.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance above VWM = 10.2 V, then rapidly avalanches at VBR = 11.4–12.6 V to limit transient overvoltage. Its glass-passivated junction ensures stable breakdown and low leakage (<5 µA at VWM), while the MELF package supports automated placement and meets UL 94 V-0 flammability rating.
The device is rated for 40 A peak forward surge current (8.3 ms half-sine), operates from –55 °C to +150 °C, and exhibits 0.081 %/°C temperature coefficient of VBR. Clamping occurs within picoseconds, with low incremental surge resistance enabling effective suppression of inductive-switching transients and lightning-induced surges on sensitive analog and digital inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V - defines precise avalanche initiation range for reliable triggering without premature conduction |
| VWM | 10.2 V - maximum continuous reverse operating voltage before leakage exceeds 5 µA |
| VC @ IPPM | 16.7 V at 24.0 A - clamping voltage during 10/1000 µs surge, limiting protected circuit stress |
| PPPM | 400 W - peak pulse power handling per 10/1000 µs waveform, supporting repetitive 0.01% duty cycle |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without degradation, critical for motor drive snubbing |
| Junction temp. range | –55 °C to +150 °C - enables deployment in automotive engine bays and industrial enclosures |
| Package | DO-213AB (GL41) - standardized MELF outline with 0.105" diameter, compatible with pick-and-place and reflow |
Pinout & Package
DO-213AB (GL41) plastic MELF package: cylindrical glass-body diode with solderable matte tin-plated ends; cathode identified by blue band (positive terminal under normal TVS operation); dimensions: D1 = 0.105" (2.67 mm), length ≈ 0.238" (6.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for unidirectional clamping | Connected to system ground or low-side return path; conducts surge current to reference plane |
| Cathode (blue band) | Protected line connection point | Connected to signal/power line being safeguarded; avalanche conduction begins here during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<5 µA), and long-term reliability under thermal cycling |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges (4 kV line-to-ground) without derating |
| MSL Level 1 (J-STD-020) | Enables standard SMT reflow without moisture sensitivity concerns - no baking required pre-assembly |
| RoHS-compliant E3 suffix | Meets JESD 201 class 1A whisker test and UL 94 V-0 flammability, suitable for commercial and industrial PCBs |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes voltage overshoot during clamping - critical for protecting 12 V logic and analog front-ends |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module (BCM) Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | DO-214AA (SMB) package; 12 V VWM, 19.9 V VC @ 21.1 A; 600 W PPPM | Higher clamping voltage (+3.2 V) and larger footprint; better suited for higher-energy surges where board space allows | Select SMBJ12A when PCB layout permits SMB package and clamping margin >19 V is acceptable |
| P6KE12A | DO-15 axial package; 12 V VWM, 19.2 V VC @ 20.9 A; 600 W PPPM; slower response than MELF | Through-hole mounting only; not compatible with automated SMT assembly; lower thermal performance in dense layouts | Choose P6KE12A only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with SMBJ12A and P6KE12A, the TGL41-12-E3/97 offers tighter VBR tolerance (±5% vs ±10%), lower clamping voltage (16.7 V vs ≥19.2 V), and superior SMT process compatibility via its DO-213AB MELF package - making it optimal for space-constrained, high-reliability industrial sensor nodes.

FAQ
What is the breakdown voltage range for TGL41-12-E3/97?
The TGL41-12-E3/97 has a guaranteed breakdown voltage (VBR) range of 11.4 V to 12.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5% tolerance ensures consistent clamping behavior across production lots and supports precise protection design for 12 V systems. The TGL41-12-E3/97 achieves this using a glass-passivated silicon junction optimized for stability under thermal cycling.
Is TGL41-12-E3/97 unidirectional or bidirectional?
TGL41-12-E3/97 is strictly unidirectional, as confirmed in the Vishay datasheet revision 11-Dec-12. It features a blue band marking the cathode and is intended for use with DC-biased lines where reverse conduction is not required. Unlike bidirectional variants, the TGL41-12-E3/97 does not suppress negative-going transients - its design targets positive overvoltage events on grounded-return systems.
What package type does TGL41-12-E3/97 use, and what are its key mechanical attributes?
TGL41-12-E3/97 uses the DO-213AB (GL41) plastic MELF package: a cylindrical glass-body outline with 0.105" (2.67 mm) diameter, 0.238" (6.0 mm) length, and matte tin-plated solderable ends. It meets UL 94 V-0 flammability and JESD 201 class 1A whisker resistance. The TGL41-12-E3/97's MELF form enables high-density automated placement and excellent thermal dissipation for its size.
Does TGL41-12-E3/97 meet RoHS and lead-free requirements?
Yes, the "E3" suffix in TGL41-12-E3/97 explicitly denotes RoHS-compliant construction per Directive 2011/65/EU, with lead-free matte tin plating and full compliance to JESD 201 class 1A whisker testing. The device also satisfies JEDEC JS709A halogen-free requirements. These certifications are documented in Vishay's Material Category Policy (doc# 99912) and apply to all units shipped with the E3/97 tape-and-reel packaging.
What is the maximum clamping voltage of TGL41-12-E3/97 under surge conditions?
The maximum clamping voltage (VC) of TGL41-12-E3/97 is 16.7 V at 24.0 A peak pulse current (IPPM) with a 10/1000 µs waveform, as specified in the Electrical Characteristics table. This value represents worst-case voltage seen by the protected circuit during standardized surge testing and is critical for ensuring downstream 12 V ICs remain within absolute maximum ratings. The TGL41-12-E3/97 achieves this low clamping via low incremental surge resistance and optimized junction design.
