Product details
Overview
TGL41-56-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping voltage transients on power and signal lines. It features 53.2 V to 58.8 V breakdown voltage (VBR), 47.8 V standoff voltage (VWM), 77.0 V clamping voltage at 5.2 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 μs). Used to protect MOSFETs and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-56-E3/97 datasheet, TGL41-56-E3/97 pinout, TGL41-56-E3/97 application, or TGL41-56-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 77.0 V clamping performance under 5.2 A surge, thermal derating above 25 °C, 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. Its glass-passivated junction enables fast response time and low incremental surge resistance, critical for suppressing inductive switching spikes and lightning-induced surges on sensitive nodes.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak temperature. Its 150 °C maximum junction temperature and -55 °C to +150 °C operating range support rugged industrial deployment.
Key Specifications

|---|---|
| VBR (min/max) | 53.2 V / 58.8 V - defines minimum voltage at which clamping begins reliably under 1.0 mA test current |
| VWM | 47.8 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 77.0 V @ 5.2 A - clamped voltage during 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 400 W - peak pulse power handling capability for non-repetitive transients |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine waveform, supporting high-energy events |
| TJ max | 150 °C - maximum junction temperature, enabling operation in hot ambient environments |
| Package | DO-213AB (GL41) - cylindrical MELF outline with solderable matte tin-plated ends |
Pinout & Package
DO-213AB (GL41) is a plastic MELF package with two solderable end terminals. The blue band denotes the cathode (positive terminal under normal TVS operation); the opposite end is the anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient clamp output node | Connected to protected line; sinks surge current to ground when VWM exceeded |
| Anode (unmarked end) | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping loop |
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 |
|---|---|---|---|
| SMBJ58A | DO-214AA package; 58 V VBR min (55.1–60.9 V); 93.6 V VC @ 4.3 A; 600 W PPPM | Higher clamping voltage and larger footprint; better suited for PCB space-constrained designs requiring higher surge margin | Select SMBJ58A when board layout allows SMC/SMB package and clamping voltage >93 V is acceptable for downstream protection |
| P6KE56A | DO-15 axial package; 56 V VBR min (53.2–58.8 V); 93.6 V VC @ 4.3 A; 600 W PPPM | Through-hole mounting; slower thermal response; not suitable for automated SMT assembly | Choose P6KE56A only for legacy through-hole designs where MELF placement is incompatible with existing pick-and-place tooling |
Compared with SMBJ58A and P6KE56A, the TGL41-56-E3/97 offers lower clamping voltage (77.0 V vs. ≥93.6 V), smaller DO-213AB footprint for high-density layouts, and MELF geometry optimized for automated placement-making it preferred for modern SMT-based industrial and telecom modules requiring tight voltage margins.

FAQ
What is the breakdown voltage range for TGL41-56-E3/97?
The TGL41-56-E3/97 has a specified breakdown voltage (VBR) range of 53.2 V to 58.8 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures reliable turn-on behavior across manufacturing lots and temperature extremes, with a typical value near 56 V. The device is designated "56A" to indicate its nominal VBR center point.
Does TGL41-56-E3/97 support bidirectional transient suppression?
No, TGL41-56-E3/97 is unidirectional only, as confirmed in the Vishay datasheet revision 11-Dec-12. It features a blue band marking the cathode and must be oriented with cathode toward the protected line. Bidirectional operation is not supported; using it in reverse-biased AC applications would result in immediate failure due to lack of reverse breakdown specification.
What is the clamping voltage of TGL41-56-E3/97 under surge conditions?
The TGL41-56-E3/97 clamps to a maximum of 77.0 V at 5.2 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is guaranteed across temperature and lot variations and defines the upper voltage limit imposed on protected circuitry during transient events, directly enabling safe interface with 75 V-rated components.
Is TGL41-56-E3/97 compatible with lead-free reflow processes?
Yes, TGL41-56-E3/97 meets MSL Level 1 per J-STD-020 and supports lead-free reflow with a maximum peak temperature of 250 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards, and the E3 suffix confirms JESD 201 Class 1A whisker resistance-ensuring robust interconnect reliability in high-volume SMT assembly.
How does the DO-213AB (GL41) package of TGL41-56-E3/97 differ from DO-214AA or DO-15?
The DO-213AB (GL41) package of TGL41-56-E3/97 is a cylindrical plastic MELF outline (0.105" diameter × 0.238" length) optimized for high-speed automated placement and thermal efficiency. Unlike DO-214AA (SMB) or DO-15 (axial), it lacks leads and relies on end-soldering-reducing parasitic inductance and improving surge response, but requiring compatible MELF feeders and stencil aperture design.
