Product details
Overview
TGL41-16-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 15.2–16.8 V breakdown voltage, and 17.8 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-16-E3/97 datasheet, TGL41-16-E3/97 pinout, TGL41-16-E3/97 application, or TGL41-16-E3/97 equivalent, key selection criteria include clamping voltage (22.5 V at 17.8 A), stand-off voltage (13.6 V), unidirectional polarity with cathode band marking, and RoHS-compliant matte tin-plated terminals suitable for automated placement.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by reverse-biased avalanche breakdown above its stand-off voltage. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for transient suppression on DC power rails and signal lines, it delivers fast response time (<1 ns), meets J-STD-020 MSL Level 1 (250 °C peak reflow), and supports repetitive surge duty cycles up to 0.01% with 10/1000 μs waveform compliance per ANSI/IEEE C62.35.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - defines reliable avalanche initiation range under 1 mA test current |
| VWM | 13.6 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 22.5 V at 17.8 A - clamping voltage limiting downstream component stress during surge |
| PPPM | 400 W (10/1000 μs) - peak transient energy absorption capability without failure |
| IFSM | 40 A (8.3 ms half-sine) - surge current rating for non-repetitive forward conduction events |
| TJ max. | 150 °C - maximum junction temperature enabling operation in high-ambient industrial environments |
| Package | DO-213AB (GL41) - compact MELF outline with solderable ends, optimized for pick-and-place |
Pinout & Package
DO-213AB (GL41) 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).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to lower-potential side of protected line; carries surge current to ground path |
| Cathode (blue band) | Avalanche breakdown terminal | Connected to higher-potential side (e.g., VIN rail); initiates clamping when VIN exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and long-term reliability under thermal cycling |
| MSL Level 1 rating | Enables single-reflow assembly without moisture sensitivity concerns (peak 250 °C) |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving protection margin for 3.3 V/5 V logic |
| RoHS-compliant E3 suffix | Meets JESD201 Class 1A whisker resistance and UL 94 V-0 flammability for safety-critical designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA package; 15 V VWM, 24.4 V VC @ 16.3 A; 600 W PPPM | Higher clamping voltage and larger footprint; better suited for PCB space-constrained but thermally robust layouts | Select SMBJ15A when board layout allows SMC/SMB pads and higher clamping margin is acceptable |
| 1.5KE15A | DO-201AD package; 15 V VWM, 23.2 V VC @ 16.6 A; 1500 W PPPM; higher IFSM (100 A) | Through-hole mounting; higher surge capacity but slower response due to parasitic inductance | Choose 1.5KE15A for legacy through-hole designs requiring >1 kA surge handling in non-high-frequency paths |
Compared with SMBJ15A and 1.5KE15A, the TGL41-16-E3/97 offers superior automated assembly compatibility via MELF packaging, tighter VBR tolerance (±5% vs ±10%), and lower profile-critical for ultra-thin industrial modules where height clearance is limited to <3.5 mm.

FAQ
What is the breakdown voltage range specified for TGL41-16-E3/97?
The TGL41-16-E3/97 has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 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 overvoltage margin design in 15 V rail protection schemes.
Does TGL41-16-E3/97 support automated optical inspection (AOI) after reflow?
Yes, the TGL41-16-E3/97 features a consistent cylindrical geometry and high-contrast blue cathode band, enabling reliable AOI detection post-reflow. Its DO-213AB (GL41) package meets IPC-A-610 Class 2/3 visual acceptability criteria for MELF components, and the matte tin plating provides uniform reflectivity for machine vision systems.
What is the maximum clamping voltage of TGL41-16-E3/97 under surge conditions?
The maximum clamping voltage (VC) of TGL41-16-E3/97 is 22.5 V at 17.8 A peak pulse current (10/1000 μs waveform). This value is measured under standardized transient conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can TGL41-16-E3/97 be used in bidirectional configurations?
No, TGL41-16-E3/97 is unidirectional only, as confirmed in the Vishay datasheet. It conducts in reverse avalanche mode only; forward conduction is limited to 3.5 V at 25 A and is not intended for bidirectional protection. For symmetrical surge suppression, a separate TGL41-16CA or dual-diode array must be selected.
What is the lead-free status and whisker resistance certification for TGL41-16-E3/97?
TGL41-16-E3/97 carries the E3 suffix, certifying RoHS compliance and JESD201 Class 1A whisker resistance. Its matte tin-plated terminals pass solderability testing per J-STD-002 and JESD22-B102, ensuring long-term interconnect integrity in high-reliability industrial applications without tin whisker growth risk.
