Product details
Overview
TGL41-43A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, designed for clamping voltage transients on signal and power lines. It features 400 W peak pulse power (10/1000 μs), 40.9–45.2 V breakdown voltage, 36.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, and 6.7 A peak pulse current with 59.3 V clamping voltage at IPPM. Used to protect MOSFETs and sensor signal lines in industrial control systems.
For engineers reviewing the TGL41-43A-E3/96 datasheet, TGL41-43A-E3/96 pinout, TGL41-43A-E3/96 application, or TGL41-43A-E3/96 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 150 °C max junction temperature, 1.0 W steady-state power dissipation, and compliance with ANSI/IEEE C62.35 surge standards.
Technical Context
This TVS diode operates as a clamping device triggered by overvoltage events exceeding its 36.8 V stand-off threshold, entering avalanche conduction to limit transient voltages to ≤59.3 V at 6.7 A. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
The GL41 (DO-213AB) MELF package supports automated placement and meets UL 94 V-0 flammability rating; polarity is marked by a blue cathode band, and terminals are matte tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 40.9 V / 45.2 V - defines minimum and maximum voltage at which avalanche conduction begins reliably under 1.0 mA test current |
| VWM | 36.8 V - maximum continuous reverse operating voltage before significant leakage; sets safe working margin below VBR |
| IPPM | 6.7 A - peak current the device safely clamps during a 10/1000 μs transient without degradation |
| VC @ IPPM | 59.3 V - clamped voltage seen by protected circuit during full-rated surge, determining downstream component stress |
| PPPM | 400 W - peak pulse power handling capability under standard 10/1000 μs waveform, defining transient energy absorption |
| TJ max | +150 °C - maximum allowable junction temperature, constraining thermal design and derating above 25 °C ambient |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), relevant for fault-current limiting in DC power paths |
Pinout & Package
GL41 (DO-213AB) is a plastic MELF package with axial leads and blue cathode band marking. The device has two terminals: anode and cathode. No internal pins - it is a two-terminal discrete diode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to ground or lower-potential rail; forms return path during clamping |
| Cathode | Transient voltage sensing and clamping node | Connected to protected line; blue band identifies this terminal; carries surge current into ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 24 V industrial buses |
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and long-term reliability under repeated transient stress |
| MSL Level 1 (J-STD-020) | Allows direct placement without baking; compatible with standard SMT reflow profiles up to 250 °C peak |
| Unidirectional polarity only | Suitable for DC-biased lines where reverse conduction must be blocked; avoids leakage in always-on circuits |
| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed industrial and telecom equipment |
Applications
| Industrial Motor Drives | Automated Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA43A-E3/96 | Same VWM (36.8 V), identical VC (59.3 V), but in DO-214AC (SMA) package - 2.5 mm × 4.5 mm surface-mount, not MELF | Requires PCB footprint change; better suited for high-density layouts where axial MELF placement is impractical | Select when board space constraints preclude DO-213AB geometry or when leveraging existing SMA land patterns |
| SMAJ43A-E3/52T | Same electrical specs (VBR, VWM, VC, PPPM), but rated for 400 W at 10/1000 μs and offered in DO-214AC with tape-and-reel option E3/52T | Compatible with pick-and-place machines using standard SMA feeders; no polarity band - cathode marked by bevelled edge | Choose for automated manufacturing lines already configured for SMA packages and requiring JESD201 Class 1A whisker compliance |
Compared with TGL41-43A-E3/96, P4SMA43A-E3/96 and SMAJ43A-E3/52T deliver identical clamping performance but differ in package form factor, mounting method, and marking scheme - requiring layout or assembly process adjustments despite functional equivalence.

FAQ
What is the maximum clamping voltage of the TGL41-43A-E3/96 under rated surge conditions?
The TGL41-43A-E3/96 exhibits a maximum clamping voltage (VC) of 59.3 V when subjected to its rated 6.7 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-43A-E3/96 maintains this clamping performance across its specified junction temperature range.
Is the TGL41-43A-E3/96 suitable for new designs given its "Not For New Designs" status?
The "Not For New Designs" designation for the TGL41-43A-E3/96 indicates Vishay recommends alternative families like P4SMA or SMAJ for future projects due to long-term supply strategy-not immediate obsolescence. The TGL41-43A-E3/96 remains fully available and supported for legacy refresh, repair, and production continuity. Engineers selecting the TGL41-43A-E3/96 should confirm program timelines align with Vishay's published lifecycle roadmap.
How does the GL41 (DO-213AB) package of the TGL41-43A-E3/96 compare thermally to DO-214AC alternatives?
The GL41 (DO-213AB) MELF package used in the TGL41-43A-E3/96 offers higher thermal mass and improved heat dissipation versus DO-214AC (SMA) due to its cylindrical geometry and larger copper cross-section. At 75 °C lead temperature, the TGL41-43A-E3/96 sustains 1.0 W steady-state power, whereas comparable SMA devices typically rate 0.6–0.8 W under identical conditions. This makes the TGL41-43A-E3/96 preferable in thermally constrained environments with sustained leakage or bias currents.
What is the meaning of the "E3/96" suffix in TGL41-43A-E3/96?
The "E3" suffix in TGL41-43A-E3/96 denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 1A whisker resistance. The "/96" specifies packaging: 7-inch diameter plastic tape-and-reel containing 1500 units, optimized for high-speed automated placement. This configuration ensures traceable, controlled moisture sensitivity level (MSL Level 1) handling for the TGL41-43A-E3/96.
Does the TGL41-43A-E3/96 support bidirectional transient suppression?
No, the TGL41-43A-E3/96 is unidirectional only, as explicitly stated in its datasheet features and electrical characteristics table. It conducts in reverse bias (cathode positive) during overvoltage events and blocks forward current beyond its 3.5 V forward voltage at 25 A. For AC or bipolar signal line protection, a separate bidirectional variant or back-to-back configuration would be required - the TGL41-43A-E3/96 does not provide symmetrical clamping.
