Product details
Overview
TGL41-24-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 22.8 V to 25.2 V breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 12.0 A peak pulse current (IPPM), 33.2 V clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs waveform), used in industrial sensor protection and MOSFET gate drive circuits.
For engineers reviewing the TGL41-24-E3/97 datasheet, TGL41-24-E3/97 pinout, TGL41-24-E3/97 application, or TGL41-24-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility with automated placement, 150 °C max junction temperature, low incremental surge resistance, and compliance with J-STD-020 MSL Level 1.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band. Its glass-passivated junction enables fast response time (<1 ns) and stable clamping under repetitive 10/1000 µs transients at 0.01% duty cycle. The device is rated for 40 A peak forward surge current (8.3 ms half-sine) and exhibits 0.097 %/°C temperature coefficient of VBR.
Designed for surface-mount assembly, the DO-213AB package supports reflow soldering up to 250 °C peak (MSL Level 1), with matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102. It delivers 1.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - ensures reliable triggering above 20.5 V operating voltage without false clamping |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 5 µA |
| IPPM | 12.0 A - peak transient current it safely clamps at 33.2 V during 10/1000 µs surge |
| VC | 33.2 V - clamped voltage seen by protected circuit under full-rated surge condition |
| PPPM | 400 W - peak pulse power handling capability for short-duration transients |
| TJ max | 150 °C - maximum junction temperature defining thermal derating envelope |
| Package | DO-213AB (GL41) - MELF-style surface-mount package optimized for high-volume pick-and-place |
Pinout & Package
DO-213AB (GL41) is a cylindrical plastic MELF package with solderable ends. Polarity is marked by a single blue band denoting the cathode (positive terminal during normal TVS operation); the opposite end is the anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient current sink | Connected to protected line; conducts surge current to ground when VWM exceeded |
| Anode (unmarked end) | Reference/return path | Typically tied to system ground or lower-potential rail to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 Level 4 surges without external series impedance |
| Glass passivated chip junction | Ensures long-term stability of VBR and low leakage under thermal cycling and humidity stress |
| MSL Level 1 (250 °C peak) | Supports standard lead-free reflow profiles without preconditioning or dry-pack requirements |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for downstream ICs |
| Uni-directional polarity only | Simplifies layout in DC-biased rails where reverse conduction is not required |
Applications
| Industrial Sensor Interface Protection | MOSFET Gate Drive Line Clamping |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in factory automation PLC modules exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: TVS diode placed between sensor output and ADC input to clamp transients before they saturate or damage precision front-end amplifiers. Use Value: Limits induced voltage spikes to ≤33.2 V, preserving 16-bit ADC accuracy and preventing latch-up in microcontroller input buffers. | Use Scenario: Safeguarding high-side N-channel MOSFET gate drivers in 24 V DC motor control H-bridges subject to inductive switching spikes. IC Role / Device Role / Timing Role: Connected from gate-to-source to suppress VGS overshoot during fast turn-off, preventing gate oxide breakdown. Use Value: Clamps gate voltage within ±20 V rating of common logic-level MOSFETs while adding <10 pF capacitance at 0 V bias. |
| Telecom Line Interface Surge Suppression | Computer Peripheral Power Rail Protection |
Use Scenario: Shielding RS-485 transceiver VCC pins in outdoor telecom base station backhaul units subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Placed on 3.3 V or 5 V supply rail upstream of LDO regulator to absorb energy before it reaches sensitive PHY ICs. Use Value: Withstands 400 W pulses without degradation, maintaining regulated output during multi-kV EFT bursts per IEC 61000-4-4. | Use Scenario: Securing USB-C VBUS lines in industrial docking stations where hot-plug events generate 100 V+ transients. IC Role / Device Role / Timing Role: Mounted directly across VBUS and GND to limit overvoltage during connector arcing or cable discharge events. Use Value: Responds in <1 ns to clamp VBUS to 33.2 V, preventing damage to USB PD controllers rated for 28 V absolute max. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | DO-214AC (SMA) package; 24 V nominal VWM; 38.9 V VC at 10.3 A; 400 W rating | Higher VC and larger footprint; less suitable for space-constrained MELF layouts | Select SMAJ24A only if board real estate allows SMA footprint and higher clamping voltage is acceptable |
| P6SMB24A | DO-214AA (SMB) package; same VWM/VBR range; 38.9 V VC at 10.3 A; 600 W rating | Higher power rating but 30% larger body; incompatible with MELF pick-and-place tooling | Choose P6SMB24A when surge energy exceeds 400 W limits and SMB mounting is feasible |
Compared with SMAJ24A and P6SMB24A, the TGL41-24-E3/97 offers identical voltage ratings but lower clamping voltage (33.2 V vs. ≥38.9 V) and MELF form factor enabling higher component density and automated placement compatibility - critical for compact industrial sensor modules.

FAQ
What is the polarity configuration of the TGL41-24-E3/97?
The TGL41-24-E3/97 is a unidirectional TVS diode with cathode identified by a blue band. During normal operation, the cathode is positive relative to the anode. This configuration makes it suitable for DC-biased lines where reverse conduction is not required, such as power rails and gate drive circuits. The TGL41-24-E3/97 does not support bidirectional transient suppression.
What is the maximum clamping voltage of the TGL41-24-E3/97 under rated surge conditions?
The TGL41-24-E3/97 has a maximum clamping voltage (VC) of 33.2 V at its rated peak pulse current of 12.0 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on the protected circuit during full-rated transient events. The TGL41-24-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-24-E3/97 compatible with lead-free reflow soldering processes?
Yes, the TGL41-24-E3/97 meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 250 °C, making it fully compatible with standard lead-free reflow profiles. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 for solderability, and the E3 suffix confirms compliance with JESD 201 Class 1A whisker testing. The TGL41-24-E3/97 requires no moisture sensitivity precautions prior to assembly.
What is the junction capacitance of the TGL41-24-E3/97 at zero bias?
The TGL41-24-E3/97 exhibits a typical junction capacitance of approximately 100 pF at 0 V bias and 1 MHz, as inferred from the family's characteristic curve (Fig. 4). This value is consistent across the TGL41 series and remains stable under DC blocking conditions. For high-speed signal line protection, this capacitance must be evaluated against bandwidth requirements - the TGL41-24-E3/97 is best suited for power rails and low-to-moderate frequency analog lines.
How does the temperature coefficient affect the breakdown voltage of the TGL41-24-E3/97?
The TGL41-24-E3/97 has a temperature coefficient of VBR of +0.097 %/°C, meaning its breakdown voltage increases linearly with junction temperature. At 125 °C, VBR rises by ~9.7% above its 25 °C value, shifting from 22.8–25.2 V to approximately 25.0–27.6 V. This positive drift ensures safe margin against false triggering at elevated temperatures and is factored into the TGL41-24-E3/97's derating curves (Fig. 2).
