Product details
Overview
TGL41-22-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) MELF package, designed for clamping voltage transients on signal and power lines. It features 20.9 V to 23.1 V breakdown voltage (VBR), 18.8 V standoff voltage (VWM), 13.1 A peak pulse current (IPPM), 30.6 V clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs). Used to protect MOSFETs and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-22-E3/97 datasheet, TGL41-22-E3/97 pinout, TGL41-22-E3/97 application, or TGL41-22-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 18.8 V working voltage margin, 30.6 V clamping performance under 13.1 A surge, and RoHS-compliant matte tin terminations per J-STD-002.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band, requiring correct orientation in series with protected circuitry. Its glass-passivated junction enables fast response time and low incremental surge resistance, critical for suppressing fast-rising transients from inductive switching.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets J-STD-020 MSL Level 1 (peak reflow 250 °C), supporting automated placement without moisture sensitivity concerns. Thermal derating follows Fig. 2, maintaining 400 W pulse rating only at TA ≤ 25 °C; above that, power must be reduced per published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering |
| VWM | 18.8 V - maximum continuous reverse voltage before leakage exceeds 5 μA, defining safe operating margin |
| IPPM | 13.1 A - peak surge current it can clamp at 10/1000 µs waveform, directly sizing protection capability |
| VC @ IPPM | 30.6 V - clamped voltage seen by downstream IC during full-rated surge, limiting stress on protected devices |
| PPPM | 400 W - transient energy handling capacity under standard 10/1000 µs test condition |
| TJ max. | 150 °C - maximum junction temperature, constraining thermal design of PCB layout and adjacent components |
| Polarity | Unidirectional - requires correct anode/cathode orientation; blue band denotes cathode (positive terminal during clamping) |
Pinout & Package
DO-213AB (GL41) plastic MELF package: cylindrical glass-body diode with solderable matte tin-plated ends; 0.105"–0.095" diameter (2.67 mm–2.41 mm), 0.238" length (6.0 mm); blue band marks cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry during forward conduction; connected to ground or lower-potential rail in unidirectional TVS configuration | Must be tied to reference potential; incorrect polarity prevents clamping and risks device failure |
| Cathode (blue band end) | Current exit during clamping; connected to line being protected (e.g., signal or supply rail) | Acts as high-impedance node until VBR exceeded; then shunts surge to anode/reference |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables sub-nanosecond response time and stable leakage behavior over temperature and life |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against common lightning-induced and inductive-switching transients in industrial environments |
| MSL Level 1 per J-STD-020 | Allows direct placement onto reflow soldered PCBs without baking, reducing manufacturing complexity |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability for safety-critical applications |
| Low incremental surge resistance | Minimizes VC overshoot during fast transients, improving clamping precision for sensitive ICs |
Applications
| Industrial Motor Control | Telecom Line Interface |
|---|---|
Use Scenario: Protecting gate drivers and feedback sensors in variable-frequency drives subjected to inductive kickback from contactor switching. IC Role / Device Role / Timing Role: Unidirectional TVS placed across motor phase outputs and isolated signal lines to clamp 60–100 V transients within 1 ns.

IC Role / Device Role / Timing Role: Primary front-end transient suppressor on differential bus lines, coordinated with secondary GDT or polymer TVS stages. Use Value: Maintains signal integrity by clamping to 30.6 V before transceiver input thresholds are exceeded, preserving ±7 V common-mode range. |
| Automotive Body Control Module | Consumer Sensor Hub |

IC Role / Device Role / Timing Role: Low-capacitance (<100 pF) unidirectional clamp on bidirectional data lines, minimizing signal distortion. Use Value: Delivers 30.6 V clamping without adding measurable delay or jitter to 400 kHz I²C timing budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ18A | DO-214AA package (SMB), 18 V VWM, 28.8 V VC @ 14.3 A, 600 W PPPM | Higher power rating but larger footprint; better suited for board space-constrained designs needing higher surge margin | Select SMBJ18A when PCB layout allows SMB footprint and system requires >400 W clamping headroom |
| P6KE22A | DO-15 axial lead, 22 V VWM, 33.2 V VC @ 12 A, 600 W PPPM, no MSL rating | Through-hole mounting only; lacks MSL Level 1 compliance and automated placement support | Choose P6KE22A for legacy through-hole assemblies where reflow compatibility is not required |
Compared with SMBJ18A and P6KE22A, the TGL41-22-E3/97 offers superior manufacturability via MELF MSL Level 1 compliance and tighter VC (30.6 V vs. ≥28.8 V), making it optimal for compact, high-volume SMT designs where clamping precision and process reliability are prioritized over absolute peak power.

FAQ
What is the polarity configuration of the TGL41-22-E3/97?
The TGL41-22-E3/97 is a unidirectional TVS diode with cathode identified by a blue band on the package. During normal operation, the cathode is positive relative to the anode; it conducts only when reverse voltage exceeds the breakdown threshold. This polarity must be observed in PCB layout to ensure proper clamping function - incorrect orientation renders the TGL41-22-E3/97 ineffective and may cause catastrophic failure under surge conditions.
What does the "E3/97" suffix indicate in TGL41-22-E3/97?
The "E3" suffix denotes RoHS-compliant construction with matte tin-plated leads meeting JESD 201 Class 1A whisker resistance, while "/97" specifies packaging in 13-inch diameter plastic tape and reel with 5000 units per reel. This configuration supports high-speed automated placement and satisfies IPC/JEDEC standards for lead-free assembly, distinguishing it from /96 (7-inch reel, 1500 units) variants of the same TGL41-22-E3/97 device.
How does the TGL41-22-E3/97 perform under elevated ambient temperatures?
The TGL41-22-E3/97 must be derated above TA = 25 °C per Figure 2 in its datasheet: peak pulse power drops linearly to zero at TA = 150 °C, and IPPM decreases proportionally. At 85 °C ambient, its usable IPPM falls to approximately 7.5 A (57% of rated 13.1 A), requiring system-level validation if deployed in thermally demanding enclosures. The TGL41-22-E3/97 retains full functionality up to TJ = 150 °C, but sustained operation near that limit necessitates thermal modeling.
Can the TGL41-22-E3/97 replace a bidirectional TVS in existing designs?
No - the TGL41-22-E3/97 is strictly unidirectional and cannot substitute for a bidirectional TVS without circuit redesign. Bidirectional devices clamp both positive and negative transients symmetrically, whereas the TGL41-22-E3/97 only suppresses reverse-polarity surges. Using TGL41-22-E3/97 in place of a bidirectional part leaves the circuit vulnerable to negative-going transients, risking unprotected IC damage. Always verify polarity requirements before selecting the TGL41-22-E3/97.
What is the clamping voltage behavior of the TGL41-22-E3/97 under real-world surge waveforms?
The TGL41-22-E3/97 specifies VC = 30.6 V at IPPM = 13.1 A using the standardized 10/1000 µs double-exponential waveform. Under faster transients (e.g., 8/20 µs lightning surge), VC may rise slightly due to junction inductance and dynamic resistance, but remains within ±5% of datasheet value per Vishay characterization. For precise system-level validation, the TGL41-22-E3/97 should be tested with actual threat waveforms per IEC 61000-4-5.
