Product details
Overview
TGL41-15-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 14.3–15.8 V breakdown voltage (VBR), and 12.8 V stand-off voltage (VWM). It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-15-E3/97 datasheet, TGL41-15-E3/97 pinout, TGL41-15-E3/97 application, or TGL41-15-E3/97 equivalent, key selection criteria include clamping voltage (21.2 V at 18.9 A), unidirectional polarity, RoHS-compliant matte tin terminals, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates exclusively in unidirectional mode with a blue-band cathode marking. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for clamping sub-microsecond transients on signal or power lines.
Rated for -55 °C to +150 °C junction temperature, it delivers 1.0 W steady-state power dissipation at TL = 75 °C and supports repetitive 10/1000 μs pulses at 0.01% duty cycle. Clamping occurs at 21.2 V under 18.9 A peak pulse current, with 0.087 %/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - ensures reliable avalanche conduction onset above circuit operating voltage |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 5 μA |
| VC @ IPPM | 21.2 V at 18.9 A - clamping voltage limiting transient energy delivered to protected device |
| PPPM | 400 W (10/1000 μs) - peak transient energy absorption capability per pulse |
| IFSM | 40 A (8.3 ms half-sine) - surge current handling for non-repetitive line faults |
| TJ max. | 150 °C - maximum junction temperature defining thermal derating envelope |
| Package | DO-213AB (GL41) - cylindrical MELF outline enabling automated placement and high power density |
Pinout & Package
DO-213AB (GL41) is a plastic MELF package with solderable matte tin-plated ends. Polarity is marked by a blue band denoting the cathode (positive terminal during TVS operation). No discrete pins - two axial terminals with symmetric geometry.
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA (SMB) package; 15 V VWM, 24.4 V VC @ 16.3 A; 600 W PPPM | Higher clamping voltage and larger footprint; better suited for PCB space-constrained but thermally robust layouts | Select when higher surge margin is needed and MELF placement equipment is unavailable |
| P6KE15A | DO-15 axial package; 15 V VWM, 23.2 V VC @ 17.2 A; 600 W PPPM; slower response due to wirebond parasitics | Manual or wave-solder compatible; lower cost but unsuitable for high-frequency transient suppression | Prefer for legacy through-hole designs or cost-sensitive consumer applications with less stringent response requirements |
Compared with SMBJ15A and P6KE15A, the TGL41-15-E3/97 offers superior surge response speed and automated placement compatibility in a compact MELF form factor, making it optimal for high-density industrial PCBs requiring repeatable, high-yield SMT assembly.

FAQ
What is the clamping voltage of the TGL41-15-E3/97 under peak pulse conditions?
The TGL41-15-E3/97 has a maximum clamping voltage (VC) of 21.2 V at 18.9 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during transient events. The TGL41-15-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-15-E3/97 suitable for bidirectional transient protection?
No, the TGL41-15-E3/97 is unidirectional only, with polarity indicated by a blue cathode band. It conducts only when the cathode is positive relative to the anode, making it appropriate for DC-biased applications like power rail protection. For AC or bipolar signal line protection, a bidirectional variant such as the TGL41-15CA would be required - the TGL41-15-E3/97 does not provide symmetrical clamping.
What is the maximum steady-state power dissipation rating for the TGL41-15-E3/97?
The TGL41-15-E3/97 has a maximum steady-state power dissipation (PD) of 1.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. This rating applies to continuous DC or low-frequency reverse leakage conditions, not transient events. Derating is required above 75 °C per the published power derating curve in the datasheet. The TGL41-15-E3/97 must not exceed this limit during normal operation.
Does the TGL41-15-E3/97 meet RoHS and lead-free assembly requirements?
Yes, the "E3" suffix indicates RoHS compliance per Directive 2011/65/EU and qualification to JESD201 Class 1A whisker testing. The matte tin-plated terminals are solderable per J-STD-002 and JESD22-B102, supporting lead-free reflow profiles with peak temperatures up to 250 °C (MSL Level 1). The TGL41-15-E3/97 is fully qualified for modern Pb-free SMT processes without modification.
What is the junction capacitance of the TGL41-15-E3/97 at zero bias?
The typical junction capacitance (CJ) of the TGL41-15-E3/97 is less than 100 pF at zero bias, 1.0 MHz, and 25 °C, as shown in Figure 4 of the datasheet. This low capacitance minimizes signal distortion on protected lines, making the TGL41-15-E3/97 suitable for medium-speed digital and analog sensor interfaces. Measured values may vary slightly with applied voltage and temperature, but the TGL41-15-E3/97 remains well below 150 pF across its operational range.
