Overview
TGL41-27A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 25.7 V minimum breakdown voltage, 28.4 V maximum breakdown voltage, and 400 W peak pulse power rating at 10/1000 μs waveform - designed for clamping inductive-switching transients on signal lines of industrial sensors and power MOSFET gate drivers.
For engineers reviewing the TGL41-27A-E3/97 datasheet, TGL41-27A-E3/97 pinout, TGL41-27A-E3/97 application, or TGL41-27A-E3/97 equivalent, key selection criteria include its 23.1 V stand-off voltage, 37.5 V max clamping voltage at 10.7 A peak pulse current, unidirectional polarity with blue-band cathode marking, and RoHS-compliant matte tin-plated leads suitable for automated placement.
Technical Context
This TVS diode operates as a voltage-clamping protection device using a glass-passivated planar junction, responding in sub-nanosecond time to transient overvoltages. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
The device delivers 400 W peak pulse power handling up to 10.7 A under 10/1000 μs waveform, with thermal derating above 25 °C per Fig. 2 and maximum junction temperature of 150 °C. It meets J-STD-020 MSL Level 1 and JESD 201 Class 1A whisker resistance requirements.

Applications
| Industrial Sensor Signal Protection | DC Motor Driver Gate Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in factory automation systems exposed to relay coil flyback and EMI. IC Role / Device Role / Timing Role: TVS diode placed across sensor output and ground to clamp transients before they reach ADC input or isolation amplifier. Use Value: Limits induced voltage to ≤37.5 V during 10.7 A surges, preserving 16-bit measurement integrity and preventing latch-up in downstream signal conditioning ICs. | Use Scenario: Safeguarding gate-source terminals of N-channel MOSFETs in H-bridge motor drivers subjected to inductive kickback from brushed DC motors. IC Role / Device Role / Timing Role: Unidirectional TVS connected between gate and source to absorb negative-going spikes while blocking normal gate drive voltage. Use Value: Clamps gate-source voltage to 37.5 V, preventing oxide breakdown in MOSFETs rated for ±20 V gate-source max, enabling reliable 24 V motor control operation. |
| Telecom Line Interface Protection | Power Supply Input Transient Suppression |
Use Scenario: Shielding RS-485 transceiver I/O pins in outdoor telecom base stations from lightning-induced surges on twisted-pair cabling. IC Role / Device Role / Timing Role: TVS deployed differential-mode across A/B lines and common-mode to ground to suppress both modes per IEC 61000-4-5. Use Value: With 23.1 V stand-off and 37.5 V clamping, maintains signal integrity for ±7 V RS-485 common-mode range while limiting fault voltage to safe levels. | Use Scenario: Suppressing switch-node ringing and load-dump transients on 24 V DC input rails of embedded controllers in vehicle-mounted equipment. IC Role / Device Role / Timing Role: Mounted between input rail and chassis ground to shunt transient energy away from upstream DC/DC converters and LDOs. Use Value: Handles 400 W pulses without degradation, maintaining <5 μA leakage at 23.1 V to avoid quiescent current penalty in always-on systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA27A-E3/97 | Same VBR range (25.7–28.4 V), but SMA package (DO-214AC); 400 W rating, 10.7 A IPPM, 37.5 V VC | SMA offers higher board-level mechanical robustness and easier manual rework; less space-efficient than MELF | Select P4SMA27A-E3/97 for hand-soldered prototypes or high-vibration environments where MELF retention is a concern |
| SMAJ27A | Identical electrical specs (VBR, VC, PPPM), but non-RoHS legacy variant; same SMA package | Lacks E3 suffix compliance (no JESD 201 Class 1A whisker test, no RoHS documentation) | Choose SMAJ27A only for legacy repair or cost-sensitive non-compliant designs where regulatory certification is not required |
Compared with P4SMA27A-E3/97 and SMAJ27A, the TGL41-27A-E3/97 provides superior automated placement yield and smaller footprint in GL41 MELF form, while delivering identical clamping performance - making it optimal for high-volume SMT production of compact industrial modules.

FAQ
What is the clamping voltage of the TGL41-27A-E3/97 at its rated peak pulse current?
The TGL41-27A-E3/97 has a maximum clamping voltage (VC) of 37.5 V when subjected to its rated 10.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during surge events, directly protecting downstream components such as MOSFET gates or sensor front-ends. The TGL41-27A-E3/97 maintains this clamping performance across its specified junction temperature range.
Is the TGL41-27A-E3/97 suitable for new designs despite the "Not For New Designs" notice in Vishay documentation?
The "Not For New Designs" notice applies to the entire TGL41 family as of November 2023, indicating Vishay recommends newer alternatives like the P4SMA series for future product development. However, the TGL41-27A-E3/97 remains fully manufactured, stocked, and supported for existing designs and legacy production. Aetrix Electronics guarantees continued supply and technical support for the TGL41-27A-E3/97 through its lifecycle management program.
How does the GL41 (DO-213AB) package of the TGL41-27A-E3/97 compare to SMA in terms of thermal performance?
The GL41 (DO-213AB) package of the TGL41-27A-E3/97 has a junction-to-ambient thermal resistance (RθJA) of approximately 150 °C/W, slightly higher than SMA's ~120 °C/W due to smaller surface area. However, both packages deliver identical 400 W peak pulse power ratings because transient dissipation depends on thermal mass and pulse duration-not steady-state conduction. The TGL41-27A-E3/97 achieves full rating at 25 °C ambient and derates linearly above that per Figure 2 in its datasheet.
What is the meaning of the "E3/97" suffix in TGL41-27A-E3/97?
The "E3" suffix indicates RoHS-compliant construction with matte tin-plated leads meeting JESD 22-B102 solderability and JESD 201 Class 1A whisker resistance. The "/97" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units - optimized for high-speed SMT placement equipment. This distinguishes it from /96 (7-inch reel, 1500 units) and confirms full compliance traceability for the TGL41-27A-E3/97.
Does the TGL41-27A-E3/97 have bidirectional capability?
No, the TGL41-27A-E3/97 is unidirectional only, as confirmed by Vishay's datasheet features and electrical characteristics table. It conducts in reverse bias above VBR but blocks forward current beyond its 3.5 V maximum forward voltage at 25 A. For AC-coupled or bipolar signal lines, a bidirectional variant (e.g., TGL41-27CA) would be required - but no such part exists in the TGL41 family. The TGL41-27A-E3/97 must be oriented with its blue-band cathode toward the higher-potential side of the protected node.
