Product details
Overview
TGL41-30-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping voltage transients on power and signal lines. It features 28.5 V to 31.5 V breakdown voltage (VBR), 25.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 9.7 A peak pulse current (IPPM), and 41.4 V maximum clamping voltage (VC) at rated current - used to protect MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-30-E3/97 datasheet, TGL41-30-E3/97 pinout, TGL41-30-E3/97 application, or TGL41-30-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 400 W surge capability, 150 °C max junction temperature, and RoHS-compliant E3/97 tape-and-reel packaging for automated SMT placement.
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 ensures stable breakdown characteristics and low leakage (<5 µA at VWM), while the MELF package delivers high thermal dissipation and robust surge handling under repetitive 0.01% duty cycle conditions.
The device complies with ANSI/IEEE C62.35 for transient suppression standards and meets J-STD-020 MSL Level 1 (peak reflow ≤250 °C). Its 0.100 %/°C temperature coefficient of VBR enables predictable voltage shift over temperature, and its 3.5 V forward voltage at 25 A supports reliable surge conduction during fault events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - defines precise clamping onset range under 1 mA test current |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| IPPM | 9.7 A - peak surge current it safely clamps at 10/1000 µs waveform without failure |
| VC | 41.4 V - maximum voltage seen across protected circuit during full-rated surge event |
| PPPM | 400 W - peak transient energy absorption capacity per single 10/1000 µs pulse |
| TJ max | 150 °C - maximum junction temperature enabling operation in hot industrial environments |
| Package | DO-213AB (GL41) - standardized MELF outline with solderable matte tin-plated ends |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with two solderable end terminals. Polarity is indicated by a blue band denoting the cathode (positive terminal under normal TVS operation); the anode is the unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode | Reference return path | Typically tied to system ground or low-impedance return; completes clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V systems |
| Glass passivated chip junction | Ensures long-term stability of VBR and low parametric drift over 10+ years of field use |
| MSL Level 1 rating (250 °C peak) | Supports standard lead-free reflow profiles without preconditioning or baking |
| Matte tin-plated leads (J-STD-002 compliant) | Guarantees reliable solder wetting and intermetallic formation in high-volume SMT assembly |
| Uni-directional polarity only | Simplifies layout for DC-biased lines where reverse conduction is not required |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protecting gate drivers and feedback sensing circuits from inductive kickback during IGBT switching in variable-frequency drives.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | DO-214AA (SMB) package; 33.3 V VBR min; 400 W PPPM; higher VC = 48.4 V | Requires PCB pad redesign; better suited for board-level surge where footprint space allows | Select SMBJ30A if DO-214AA is preferred for thermal mass or existing layout reuse |
| 1.5KE30A | DO-201AD (Axial) package; 31.8 V VBR min; 1500 W PPPM; larger size and manual assembly | Used in legacy through-hole designs; unsuitable for high-density SMT | Choose 1.5KE30A only for repair or low-volume axial builds where MELF placement is unavailable |
Compared with SMBJ30A and 1.5KE30A, the TGL41-30-E3/97 offers superior SMT manufacturability in compact MELF form, tighter VBR tolerance (±5.3%), and lower clamping voltage - making it optimal for space-constrained, high-reliability DC power rail protection.

FAQ
What is the breakdown voltage range specified for TGL41-30-E3/97?
The TGL41-30-E3/97 has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5.3% tolerance ensures predictable clamping behavior across production lots and temperature extremes up to 150 °C.
Does TGL41-30-E3/97 support lead-free reflow soldering?
Yes, TGL41-30-E3/97 meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 250 °C, fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with JESD 22-B102 and J-STD-002 for reliable wetting and intermetallic formation.
What is the maximum clamping voltage of TGL41-30-E3/97 at its rated peak pulse current?
The TGL41-30-E3/97 exhibits a maximum clamping voltage (VC) of 41.4 V when subjected to its rated 9.7 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events.
Is TGL41-30-E3/97 suitable for bidirectional transient suppression?
No, TGL41-30-E3/97 is unidirectional only, with polarity marked by a blue cathode band. It must be oriented with cathode toward the protected line and anode to ground. For bidirectional protection, a separate symmetric TVS or dual-diode configuration is required.
What packaging format does TGL41-30-E3/97 ship in?
TGL41-30-E3/97 ships in 13" diameter plastic tape-and-reel format (package code /97), with 5000 units per reel. The E3 suffix confirms RoHS compliance and JESD 201 Class 1A whisker resistance, supporting high-reliability automated placement in commercial-grade applications.
