Product details
Overview
TGL41-75-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for surge protection on DC power rails and signal lines. It features 71.3 V to 78.8 V breakdown voltage (VBR), 64.1 V standoff voltage (VWM), 103 V clamping voltage at 3.9 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 μs waveform), used in industrial sensor interface protection.
For engineers reviewing the TGL41-75-E3/97 datasheet, TGL41-75-E3/97 pinout, TGL41-75-E3/97 application, or TGL41-75-E3/97 equivalent, key selection criteria include unidirectional polarity, 64.1 V working voltage, 103 V clamping performance under 3.9 A transient, DO-213AB mechanical compatibility, and RoHS-compliant matte tin plating per J-STD-002.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band, requiring correct polarity alignment in series with protected circuitry. Its glass-passivated junction ensures stable VBR temperature coefficient of 0.108 %/°C and low incremental surge resistance for consistent clamping behavior.
It delivers 400 W peak pulse power only up to 91 V; above that threshold, rating drops to 200 W - confirmed by derating curve Fig. 2. The device supports 40 A non-repetitive forward surge current (8.3 ms half-sine) and maintains operation from −55 °C to +150 °C junction temperature.

|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in factory automation PLC modules exposed to relay coil kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and system ground to clamp transients before they reach ADC input or op-amp buffer. Use Value: Limits voltage excursion to ≤103 V during 3.9 A surges, preserving signal integrity and preventing latch-up in 3.3 V or 5 V interface ICs. | Use Scenario: Safeguarding RS-485 transceiver data lines on telecom base station line cards subjected to lightning-induced surges. IC Role / Device Role / Timing Role: TVS deployed differential-mode across A/B bus lines, referenced to local ground plane, absorbing common-mode energy via PCB layout coupling. Use Value: Clamps fast-rising transients within nanoseconds while maintaining <5 μA leakage at 64.1 V, avoiding false triggering or signal degradation. |
| Computer Power Supply Input Protection | Automotive Body Control Module (BCM) Inputs |
Use Scenario: Guarding 12 V DC input rails of ATX auxiliary power supplies against load dump and ESD events during hot-plug operations. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-rail, cathode-to-ground, acting as last-line defense before bulk capacitance and regulator inputs. Use Value: Handles 400 W peak pulses without degradation, sustaining 40 A surge current to prevent catastrophic failure during 12 V system faults. | Use Scenario: Shielding switch inputs (e.g., door lock actuator signals) in BCMs from inductive switching noise generated by window motor relays. IC Role / Device Role / Timing Role: TVS installed at connector entry point, shunting transient energy directly to chassis ground before reaching microcontroller GPIO pins. Use Value: Operates reliably from −40 °C to +125 °C ambient, with 0.108 %/°C VBR drift ensuring consistent clamping across vehicle thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ70A | DO-214AC (SMA) package; 70 V VWM, 115 V VC @ 3.5 A; 400 W rating | Higher clamping voltage and larger footprint; less suitable for space-constrained MELF layouts | Select SMAJ70A only if board real estate allows SMA footprint and higher VC is acceptable for protected IC's absolute max rating |
| P6SMB70A | DO-214AA (SMB) package; 70 V VWM, 113 V VC @ 3.5 A; 600 W rating | Higher power rating but slower response due to larger junction capacitance (~100 pF vs. ~30 pF for TGL41-75) | Choose P6SMB70A when surge energy exceeds 400 W but sub-nanosecond response is not required |
Compared with SMAJ70A and P6SMB70A, the TGL41-75-E3/97 offers tighter VBR tolerance (±5 % vs. ±10 %), lower clamping voltage (103 V vs. ≥113 V), and smaller DO-213AB footprint - making it optimal for high-density, precision-clamping applications where layout area and voltage margin are critical.

FAQ
What is the polarity configuration of the TGL41-75-E3/97?
The TGL41-75-E3/97 is a unidirectional TVS diode with cathode identified by a blue band on the package. During normal operation, the cathode is held at a higher potential than the anode; conduction occurs only when reverse voltage exceeds VWM. This configuration prevents forward conduction in DC-powered circuits and ensures precise clamping directionality. The TGL41-75-E3/97 must be oriented correctly on PCBs to avoid unintended shorting or ineffective protection.
Does the TGL41-75-E3/97 meet RoHS and lead-free requirements?
Yes, the TGL41-75-E3/97 carries the "E3" suffix indicating full compliance with RoHS Directive 2011/65/EU and JEDEC JS709A halogen-free standards. Its matte tin-plated terminals satisfy J-STD-002 solderability requirements and JESD 22-B102 intermetallic formation limits. The TGL41-75-E3/97 is rated for peak reflow temperatures up to 250 °C and classified as MSL Level 1, eliminating need for moisture sensitivity handling prior to assembly.
What is the maximum clamping voltage of the TGL41-75-E3/97 under standard test conditions?
The TGL41-75-E3/97 exhibits a maximum clamping voltage (VC) of 103 V when subjected to a 10/1000 μs waveform at 3.9 A peak pulse current (IPPM). This value is measured per ANSI/IEEE C62.35 and represents the upper limit of voltage seen by downstream components during transient events. The TGL41-75-E3/97 achieves this performance with low incremental surge resistance, ensuring minimal voltage overshoot beyond the specified VC.
Can the TGL41-75-E3/97 be used in automotive under-hood applications?
Yes, the TGL41-75-E3/97 supports junction temperatures from −55 °C to +150 °C and is qualified for industrial and automotive environments per its thermal and surge specifications. Its DO-213AB package passes MSL Level 1 and JESD 201 Class 1A whisker testing, enabling deployment in engine control units and body control modules. However, system-level validation is required for specific under-hood thermal profiles and transient threat levels before final qualification of the TGL41-75-E3/97.
How does the temperature coefficient affect the TGL41-75-E3/97's breakdown voltage?
The TGL41-75-E3/97 has a VBR temperature coefficient of +0.108 %/°C, meaning its breakdown voltage increases linearly with rising junction temperature. At 125 °C, VBR rises approximately 10.8 % above its 25 °C value - from 71.3–78.8 V to ~79–87 V. This positive drift ensures safe margin against premature conduction at elevated temperatures. Designers must account for this shift when setting VWM margins relative to maximum operating voltage in the TGL41-75-E3/97 application.
