Product details
Overview
TGL41-47A-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 44.7–49.4 V breakdown voltage, and 6.2 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-47A-E3/97 datasheet, TGL41-47A-E3/97 pinout, TGL41-47A-E3/97 application, or TGL41-47A-E3/97 equivalent, key selection factors include clamping voltage (64.8 V at 6.2 A), stand-off voltage (40.2 V), unidirectional polarity, and DO-213AB package compatibility with automated placement.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction only during overvoltage events on the cathode-anode path, with a maximum clamping voltage of 64.8 V at 6.2 A IPPM.
Designed for transient suppression per ANSI/IEEE C62.35, it operates across –55 °C to +150 °C junction temperature and meets J-STD-020 MSL Level 1 (250 °C lead-free reflow). The blue band denotes the cathode terminal, and its 1.0 W steady-state power dissipation supports continuous operation under leakage-limited conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA47A-E3/97 | Same 47 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 6.2 A IPPM, 64.8 V VC | Surface-mount footprint differs (rectangular SMA vs. cylindrical MELF); requires PCB pad redesign | Select when board space allows larger body or existing design uses SMA footprints |
| SMBJ47A | DO-214AA package; identical electrical specs (VBR 44.7–49.4 V, VC 64.8 V), but 600 W PPPM rating | Higher surge margin supports harsher environments; larger thermal mass improves reliability under repeated stress | Choose for mission-critical industrial controls where extended surge endurance is prioritized over size |
Compared with TGL41-47A-E3/97, P4SMA47A-E3/97 offers identical electrical performance in a different package requiring layout change, while SMBJ47A delivers higher 600 W pulse power in a larger DO-214AA body-ideal for designs needing greater surge headroom without altering circuit topology.

FAQ
What is the clamping voltage of the TGL41-47A-E3/97 under peak pulse conditions?
The TGL41-47A-E3/97 has a maximum clamping voltage (VC) of 64.8 V at 6.2 A peak pulse current (IPPM) using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-47A-E3/97 maintains this clamping performance across its full operating temperature range.
Is the TGL41-47A-E3/97 suitable for new designs?
No-the Vishay datasheet explicitly states "Not For New Designs" for the TGL41-47A-E3/97, with P4SMA47A-E3/97 recommended as an alternative. While fully functional and supported for existing production, new designs should evaluate the P4SMA series or SMBJ47A for long-term availability and enhanced package options. The TGL41-47A-E3/97 remains available through Aetrix Electronics for legacy program continuity.
What does the "E3/97" suffix indicate in TGL41-47A-E3/97?
The "E3" suffix denotes RoHS-compliant construction meeting JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability standards. The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This format supports high-volume SMT assembly and is distinct from the /96 variant (7-inch reel, 1500 units). The TGL41-47A-E3/97 retains identical electrical specifications regardless of reel size.
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-47A-E3/97?
The GL41 (DO-213AB) MELF package provides higher surface-area-to-volume ratio than flat packages, enabling efficient heat dissipation during transient events. With a 1.0 W steady-state power rating and 400 W peak pulse capability, the TGL41-47A-E3/97 achieves effective thermal management without heatsinking in typical PCB layouts. Its cylindrical geometry also minimizes mechanical stress during thermal cycling, enhancing reliability in industrial environments where the TGL41-47A-E3/97 is commonly deployed.
Can the TGL41-47A-E3/97 be used in bidirectional configurations?
No-the TGL41-47A-E3/97 is specified for unidirectional polarity only, with a blue band marking the cathode. It is not rated for reverse conduction or symmetrical clamping. For AC or bidirectional signal line protection, engineers must select purpose-built bidirectional TVS diodes such as the SMBJ47CA or P4SMA47CA. Using the TGL41-47A-E3/97 in reverse-biased configurations risks premature failure due to lack of reverse breakdown specification.
