Product details
Overview
TGL41-16A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, featuring 15.2–16.8 V breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), and 17.8 A peak pulse current (IPPM). It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-16A-E3/97 datasheet, TGL41-16A-E3/97 pinout, TGL41-16A-E3/97 application, or TGL41-16A-E3/97 equivalent, key selection criteria include clamping voltage (22.5 V at IPPM), unidirectional polarity with blue-band cathode marking, low incremental surge resistance, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode uses a glass-passivated planar junction for stable breakdown characteristics and fast response to ESD and surge events. Its DO-213AB package enables automated placement and meets UL 94 V-0 flammability rating with MSL Level 1 moisture sensitivity.
Designed for single-pulse transient suppression, it delivers 400 W peak pulse power at TA = 25 °C (derated above 25 °C), supports 40 A non-repetitive forward surge current (8.3 ms half-sine), and operates across –55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines reliable conduction onset under transient stress; ensures clamping begins before downstream device damage thresholds. |
| VWM | 13.6 V - maximum continuous reverse voltage without significant leakage; sets safe operating margin below breakdown. |
| IPPM | 17.8 A - peak current handled during 10/1000 μs surge; determines minimum trace width and PCB layout robustness. |
| VC @ IPPM | 22.5 V - clamped voltage during full-rated surge; directly limits voltage seen by protected IC or MOSFET gate. |
| PPPM | 400 W - peak pulse power dissipation capability; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| Leakage @ VWM | 5.0 μA - reverse leakage at stand-off voltage; ensures minimal standby power loss in battery-powered systems. |
| TJ max | +150 °C - maximum junction temperature; supports operation in enclosed industrial enclosures without forced cooling. |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable axial leads; blue band denotes cathode (positive terminal during TVS conduction); 0.105"–0.095" diameter, 0.238" length; RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or low-side return path; forms current path during transient clamping. |
| Cathode (blue band) | Transient voltage sensing and clamping node | Connected to protected line (e.g., MOSFET drain or IC supply rail); conducts when VIN exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables compliance with IEC 61000-4-5 surge immunity requirements up to 2 kV (line-to-earth) in industrial equipment. |
| Glass-passivated planar junction | Delivers stable VBR tolerance (±5%) and low dynamic impedance over lifetime, critical for repeatable protection performance. |
| MSL Level 1 (250 °C peak reflow) | Supports standard lead-free SMT reflow profiles without preconditioning, reducing manufacturing complexity. |
| Unidirectional polarity only | Simplifies circuit design for DC-biased rails (e.g., 12 V/24 V power inputs) where reverse conduction is not required. |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for safety-critical industrial and telecom infrastructure applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA16A-E3/97 | Same VBR range (15.2–16.8 V), but SMA package (DO-214AC); 400 W rating; higher thermal resistance (RθJA ≈ 110 °C/W vs. GL41's ~85 °C/W). | Surface-mount compatible with standard gull-wing footprints; less suitable for high-density MELF layouts or automated MELF placement lines. | Select P4SMA16A-E3/97 when board space permits larger footprint and existing assembly lines support SMA packages. |
| SMAJ16A | Identical electrical specs (VBR, VC, PPPM) but legacy non-RoHS variant; same DO-214AC package; no JESD201 whisker testing. | Not compliant with modern RoHS or automotive AEC-Q200 requirements; limited to legacy industrial repair programs. | Choose SMAJ16A only for cost-sensitive, non-certified replacement in non-regulated environments where RoHS is not mandated. |
Compared with TGL41-16A-E3/97, P4SMA16A-E3/97 offers identical clamping performance in a more thermally constrained but widely supported package, while SMAJ16A provides legacy compatibility at the expense of regulatory compliance and long-term reliability assurance.

FAQ
What is the clamping voltage of the TGL41-16A-E3/97 under full-rated surge conditions?
The TGL41-16A-E3/97 has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current of 17.8 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during standardized surge events. The TGL41-16A-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-16A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-16A-E3/97 as "Not For New Designs" in its official documentation (Document Number 88403, Revision 14-Nov-2023). Engineers developing new products should consider the recommended alternative, P4SMA16A-E3/97, which offers comparable electrical performance in an industry-standard SMA package with ongoing production support.
What does the /97 suffix indicate in TGL41-16A-E3/97?
Per Vishay's ordering information, the /97 suffix specifies the packaging format: 13-inch diameter plastic tape and reel containing 5000 units. This contrasts with /96, which denotes 7-inch reels of 1500 units. Both share identical electrical and mechanical specifications; the suffix solely identifies reel size and quantity for logistics and assembly line setup.
How is polarity identified on the TGL41-16A-E3/97 package?
The TGL41-16A-E3/97 uses a blue band to mark the cathode terminal, which is the positive side during transient conduction. When installed, the blue band must face the line being protected (e.g., MOSFET drain or IC supply rail), while the unmarked end connects to ground. This unidirectional configuration is confirmed in the mechanical data section of the Vishay datasheet (Document 88403).
What is the maximum junction temperature rating for the TGL41-16A-E3/97?
The TGL41-16A-E3/97 has a maximum junction temperature (TJ) rating of +150 °C, as specified in the "Maximum Ratings" table of Vishay's datasheet (Document 88403). This allows reliable operation in sealed industrial enclosures or near heat-generating components, provided PCB copper area and ambient conditions maintain junction temperature within this limit during surge events and steady-state operation.
