Product details
Overview
TGL41-33A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, designed for surge protection on signal and power lines. It features 31.4 V minimum breakdown voltage (VBR), 28.2 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 45.7 V maximum clamping voltage at 8.8 A, and operates from −55 °C to +150 °C junction temperature.
For engineers reviewing the TGL41-33A-E3/97 datasheet, TGL41-33A-E3/97 pinout, TGL41-33A-E3/97 application, or TGL41-33A-E3/97 equivalent, key selection considerations include unidirectional polarity, DO-213AB mechanical compatibility, 400 W transient handling capability, low 0.101 %/°C VBR temperature coefficient, and RoHS-compliant matte tin-plated terminals suitable for automated placement.
Technical Context
This TVS diode employs a glass-passivated planar chip junction for stable breakdown characteristics and fast response to transients. Its unidirectional configuration provides forward conduction only during reverse overvoltage events, with clamping action triggered above 28.2 V and fully limiting to ≤45.7 V at rated 8.8 A peak pulse current.
The device is rated for 400 W peak pulse power under 10/1000 µs waveform at 0.01 % duty cycle, derates linearly above 25 °C ambient, and supports 40 A non-repetitive forward surge (8.3 ms half-sine). It meets J-STD-020 MSL Level 1 and JESD 201 Class 1A whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines precise voltage threshold where clamping begins; ensures reliable turn-on before downstream IC damage |
| VWM | 28.2 V - maximum continuous reverse operating voltage; must exceed system nominal voltage to prevent leakage or false triggering |
| VC @ IPPM | 45.7 V at 8.8 A - clamped voltage seen by protected circuit during worst-case transient; determines safe margin for downstream components |
| PPPM | 400 W (10/1000 µs) - peak transient energy absorption capacity; validates suitability for IEC 61000-4-5 Level 3/4 surge testing |
| IFSM | 40 A (8.3 ms half-sine) - withstands high-current inductive kick without bond wire failure; critical for relay or solenoid interface protection |
| TJ Range | −55 °C to +150 °C - enables deployment in automotive engine bays, industrial motor drives, and outdoor telecom enclosures |
| Package | GL41 (DO-213AB) - cylindrical MELF outline with solderable ends; compatible with standard pick-and-place feeders and reflow profiles |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with two solderable axial terminals. Polarity is marked by a blue band indicating the cathode (positive terminal under reverse-bias clamping condition). No internal pins-device functions as a two-terminal bidirectional-capable unidirectional suppressor.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-bias operation | Connected to ground or low-impedance return path; forms clamping loop with cathode |
| Cathode (blue band) | Transient voltage sensing and clamping node | Connected to protected line (e.g., USB VBUS, RS-485 A/B); conducts surge current to anode when VLINE > VC |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against lightning-induced surges and inductive switching transients per IEC 61000-4-5 |
| Glass-passivated planar junction | Delivers stable VBR tolerance (±5 %) and low leakage (<5 µA at VWM) across temperature and lifetime |
| MSL Level 1 (250 °C peak reflow) | Supports single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination |
| Matte tin-plated leads (J-STD-002/JESD 22-B102) | Ensures reliable solder wetting and intermetallic formation; eliminates post-reflow voiding or dewetting risk |
| 0.101 %/°C VBR tempco | Minimizes drift in clamping threshold over wide ambient ranges-critical for precision sensor or ADC front-end protection |
Applications
| Industrial Motor Control | Automotive Body Electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA33A-E3/97 | Same 33 V nominal rating, but SMA package (DO-214AC); 400 W rating, 44.2 V clamping at 9.1 A | Surface-mount flat leaded package requires different PCB footprint and thermal relief design | Select when board space constraints favor rectangular SMD layout or when existing SMA land patterns are standardized |
| SMAJ33A-E3/52 | DO-214AC package, 400 W rating, 53.3 V clamping at 7.5 A; higher VC and lower IPPM than TGL41-33A-E3/97 | Higher clamping voltage reduces protection margin for 3.3 V/5 V circuits; suited for 24 V+ systems | Choose only if legacy SMAJ footprint reuse is mandatory and system can tolerate ≥53 V clamping during surge events |
Compared with P4SMA33A-E3/97 and SMAJ33A-E3/52, the TGL41-33A-E3/97 offers superior clamping performance (45.7 V vs. ≥44.2 V/53.3 V) in a compact MELF form factor ideal for high-density automated assembly, with tighter VBR tolerance and lower temperature coefficient for stable protection across thermal environments.

FAQ
What is the breakdown voltage range for TGL41-33A-E3/97?
The TGL41-33A-E3/97 has a guaranteed breakdown voltage (VBR) range of 31.4 V to 34.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight ±5 % tolerance ensures predictable clamping onset across production lots and temperature extremes, making TGL41-33A-E3/97 suitable for designs requiring precise overvoltage thresholds.
Is TGL41-33A-E3/97 suitable for bidirectional transient protection?
No, TGL41-33A-E3/97 is unidirectional only, as confirmed in its Vishay datasheet. It protects against positive transients on the cathode side relative to the anode. For bidirectional protection, two TGL41-33A-E3/97 devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMBJ33CA should be selected instead of TGL41-33A-E3/97.
What does the "E3/97" suffix mean in TGL41-33A-E3/97?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "/97" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units-standard for high-volume automated assembly of TGL41-33A-E3/97.
How does TGL41-33A-E3/97 perform under elevated temperature conditions?
TGL41-33A-E3/97 derates linearly above 25 °C ambient per Figure 2 in its datasheet: peak pulse power drops to 200 W above 91 V and follows a defined curve down to zero at 150 °C junction temperature. Its 0.101 %/°C VBR temperature coefficient ensures minimal shift in clamping threshold, maintaining protection integrity in under-hood or enclosed industrial environments where TGL41-33A-E3/97 operates.
Why is TGL41-33A-E3/97 marked as "Not For New Designs"?
Vishay designates TGL41-33A-E3/97 as "Not For New Designs" because it has been superseded by newer platforms like the P4SMA series, which offer improved surge robustness and broader voltage coverage. However, TGL41-33A-E3/97 remains fully supported for existing designs, with active manufacturing, full datasheet documentation, and guaranteed supply continuity through Aetrix Electronics for legacy program sustainment.
