Product details
Overview
TGL41-30A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, with 28.5 V to 31.5 V breakdown voltage (VBR), 25.6 V stand-off voltage (VWM), and 400 W peak pulse power (10/1000 µs). It clamps transients to ≤41.4 V at 9.7 A peak pulse current and is used for protecting MOSFETs and signal lines in industrial sensor units.
For engineers reviewing the TGL41-30A-E3/97 datasheet, TGL41-30A-E3/97 pinout, TGL41-30A-E3/97 application, or TGL41-30A-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, 41.4 V clamping voltage at rated IPPM, thermal derating above 25 °C, and RoHS-compliant matte tin-plated terminals meeting J-STD-002 solderability.
Technical Context
This TVS diode employs a glass-passivated planar junction for stable breakdown behavior and low incremental surge resistance. Its unidirectional configuration provides forward conduction only during reverse transient suppression, with VF = 3.5 V at 25 A ensuring predictable forward drop during surge events.
The device operates across -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. Its 0.100 %/°C VBR temperature coefficient ensures predictable voltage drift over temperature in protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - defines guaranteed breakdown initiation window under 1.0 mA test current |
| VWM | 25.6 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA |
| VC @ IPPM | 41.4 V - clamped voltage seen by protected circuit at 9.7 A 10/1000 µs surge |
| PPPM | 400 W - peak transient energy absorption capability under standard waveform |
| IFSM | 40 A - maximum non-repetitive forward surge current (8.3 ms half-sine) |
| Junction Temp Range | -55 °C to +150 °C - operational limits for PCB-level thermal design and reliability modeling |
| Package | GL41 (DO-213AB) - cylindrical MELF outline enabling automated placement and high power density |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with axial leads; polarity marked by blue band indicating cathode (positive terminal during TVS operation). Leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 1A whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail; carries full surge current during clamping |
| Cathode (blue band) | Transient voltage sensing and clamping node | Connected to protected line; enters avalanche conduction when VLINE exceeds VBR, shunting surge to ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated planar junction | Ensures stable VBR tolerance and long-term reliability under repetitive surge stress |
| 400 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 surges without derating |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients (<1 ns rise time) |
| MSL Level 1, 250 °C peak reflow | Enables single-pass lead-free assembly without moisture-related popcorning |
| Unidirectional polarity only | Simplifies layout for DC-biased lines where reverse conduction is not required |
Applications
| Industrial Sensor Signal Protection | DC Motor Drive Gate Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in factory automation PLC I/O modules exposed to relay coil flyback and ESD. IC Role / Device Role / Timing Role: TVS diode placed between sensor output and ADC input to clamp transients before they saturate front-end amplifiers. Use Value: Clamps 41.4 V at 9.7 A while maintaining 25.6 V stand-off, preserving signal integrity below 3.3 V or 5 V ADC reference rails. | Use Scenario: Safeguarding gate drivers and MOSFET gates in 24 V DC motor H-bridge controllers subject to inductive kickback during PWM switching. IC Role / Device Role / Timing Role: Unidirectional TVS connected from gate to source to suppress negative-going spikes exceeding VGS rating. Use Value: Limits gate-source voltage to ≤41.4 V during 40 A IFSM events, preventing oxide damage in logic-level MOSFETs. |
| Telecom Line Interface Protection | Computer Peripheral Port Protection |
Use Scenario: Shielding RS-485 transceiver data lines in base station remote radio units from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; this unidirectional device used on DC-biased bias networks feeding termination resistors. Use Value: Withstands 400 W pulses while holding leakage <5 µA at 25.6 V, avoiding false triggering in bias-sensitive differential receivers. | Use Scenario: Guarding USB 2.0 D+/D− lines in docking stations against ESD and hot-plug transients during peripheral connection. IC Role / Device Role / Timing Role: Placed in series with ferrite beads on each line to limit surge current into transceiver ESD diodes. Use Value: Delivers 41.4 V clamping at 9.7 A with 0.100 %/°C VBR stability, ensuring consistent protection across ambient temperature ranges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA30A-E3 | Same VBR range (28.5–31.5 V), but SMA package (DO-214AC); 400 W PPPM, 9.7 A IPPM, 41.4 V VC | Surface-mount flat leaded package vs. cylindrical MELF; requires different pad layout and pick-and-place nozzle | Select P4SMA30A-E3 when board space constraints favor rectangular footprint or existing SMA land patterns exist. |
| SMAJ30A | Identical electrical specs (VBR, VC, PPPM), DO-214AC package, but higher leakage (10 µA at VWM) and no MSL Level 1 qualification | Lacks J-STD-020 MSL Level 1 rating; not recommended for high-reliability lead-free reflow processes | Choose SMAJ30A only for cost-sensitive consumer designs where MSL compliance is not mandated. |
Compared with TGL41-30A-E3/97, P4SMA30A-E3 offers identical protection performance in a more common SMD package but requires PCB redesign, while SMAJ30A sacrifices MSL Level 1 and tighter leakage for lower cost-neither is pin-compatible due to differing DO-213AB vs. DO-214AC footprints.

FAQ
What is the clamping voltage of the TGL41-30A-E3/97 under its rated peak pulse current?
The TGL41-30A-E3/97 has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current (IPPM) of 9.7 A using a 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during surge events. The TGL41-30A-E3/97 maintains this clamping performance across its specified junction temperature range.
Is the TGL41-30A-E3/97 suitable for lead-free reflow soldering processes?
Yes, the TGL41-30A-E3/97 is qualified to MSL Level 1 per J-STD-020 with a maximum lead-free reflow peak temperature of 250 °C. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the GL41 package construction prevents moisture-related defects during standard Pb-free profiles. The TGL41-30A-E3/97 supports single-pass assembly without prebaking.
Does the TGL41-30A-E3/97 have bidirectional capability?
No, the TGL41-30A-E3/97 is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts in reverse avalanche mode to clamp positive transients on the cathode side but does not protect against negative excursions on the anode. For bidirectional protection, separate devices or a dedicated bidirectional TVS such as SMBJ30CA would be required. The TGL41-30A-E3/97's blue band marks the cathode terminal.
What is the maximum steady-state power dissipation of the TGL41-30A-E3/97?
The TGL41-30A-E3/97 has a maximum steady-state power dissipation (PD) of 1.0 W when mounted on an infinite heatsink at TL = 75 °C. This rating applies to continuous DC or low-duty-cycle conditions-not transient suppression. Derating is required above 25 °C ambient, per the power derating curve in Figure 5 of the datasheet. The TGL41-30A-E3/97 relies on short-duration pulse handling rather than sustained power dissipation.
How does the temperature coefficient affect the breakdown voltage of the TGL41-30A-E3/97?
The TGL41-30A-E3/97 has a VBR temperature coefficient of +0.100 %/°C, meaning its breakdown voltage increases by approximately 0.0285 V/°C (0.100 % of 28.5 V) above 25 °C. This positive drift ensures higher clamping thresholds at elevated temperatures, reducing risk of false triggering in warm environments. The TGL41-30A-E3/97's coefficient is confirmed in the Electrical Characteristics table on page 2 of document 88403.
