Product details
Overview
TGL41-56-E3/96 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), 53.2–58.8 V breakdown voltage, and 77.0 V clamping voltage at 5.2 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in industrial and telecom equipment.
For engineers reviewing the TGL41-56-E3/96 datasheet, TGL41-56-E3/96 pinout, TGL41-56-E3/96 application, or TGL41-56-E3/96 equivalent, key selection criteria include unidirectional polarity, 47.8 V stand-off voltage, low incremental surge resistance, fast response time, and RoHS-compliant matte tin-plated terminals suitable for automated placement.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown range (53.2–58.8 V), limiting transient energy to protected circuits. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge conditions.
The DO-213AB (GL41) MELF package provides high thermal dissipation capability and meets UL 94 V-0 flammability rating. With a maximum junction temperature of 150 °C and MSL Level 1 rating (peak reflow 250 °C), it supports lead-free reflow assembly without derating penalties.
Key Specifications

|---|---|
| VBR (min/max) | 53.2 V / 58.8 V - defines minimum clamping onset threshold and maximum variation across production lot |
| VWM | 47.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 77.0 V at 5.2 A - clamped voltage seen by protected circuit during full-rated 400 W transient |
| PPPM | 400 W (10/1000 μs) - peak transient energy absorption capacity under standard waveform |
| IFSM | 40 A (8.3 ms half-sine) - surge current handling for non-repetitive AC line fault events |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient current sink node | Connected to protected line; conducts avalanche current to ground reference during overvoltage event |
| Anode | Reference return path | Typically tied to system ground or low-impedance return plane; completes clamping loop |

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 (ON Semiconductor) | DO-214AA package; 58.0–64.4 V VBR; 400 W PPPM; higher clamping voltage (93.6 V @ 4.3 A) | Surface-mount SMB footprint requires PCB layout change; lower peak pulse current rating | Select when board space permits larger SMC/SMB package and higher clamping margin is acceptable |
| P6SMB58A (Littelfuse) | Same DO-214AA package; identical VBR and PPPM; 93.6 V VC @ 4.3 A; 1.0 W PD | Higher thermal resistance due to epoxy body; less suitable for high ambient temperature enclosures | Prefer for cost-sensitive consumer designs where MELF handling is not supported in SMT line |
Compared with SMBJ58A and P6SMB58A, TGL41-56-E3/96 offers lower clamping voltage (77.0 V vs. ≥93.6 V) and superior thermal performance in MELF form, making it optimal for compact, high-reliability industrial modules requiring minimal voltage overshoot.

FAQ
What is the breakdown voltage range of the TGL41-56-E3/96?
The TGL41-56-E3/96 has a specified breakdown voltage (VBR) range of 53.2 V to 58.8 V at 1.0 mA test current, per Vishay Document Number 88403. This range ensures consistent clamping behavior across manufacturing lots and allows design margin for worst-case transient suppression. The value is measured under controlled conditions at TA = 25 °C and reflects the voltage at which the device enters avalanche conduction.
Is the TGL41-56-E3/96 unidirectional or bidirectional?
The TGL41-56-E3/96 is a unidirectional TVS diode, as confirmed in the "FEATURES" section of the Vishay datasheet: "Available in uni-directional polarity only." Its blue band marks the cathode, and it is intended for use in DC circuits where reverse polarity protection is not required. Bidirectional variants are not offered in the TGL41-56A part number.
What is the clamping voltage of the TGL41-56-E3/96 at its rated peak pulse current?
The TGL41-56-E3/96 clamps to a maximum of 77.0 V at its rated peak pulse current of 5.2 A (10/1000 μs waveform), as listed in the "ELECTRICAL CHARACTERISTICS" table. This clamping voltage represents the upper limit seen by protected circuitry during full-rated transient events and is critical for ensuring downstream components remain within safe operating voltage limits.
Does the TGL41-56-E3/96 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-56-E3/96 carries the E3 suffix, indicating RoHS compliance per Directive 2011/65/EU and qualification to JESD 201 Class 1A whisker testing. Its matte tin-plated terminals are solderable per J-STD-002 and JESD 22-B102, and the device is rated MSL Level 1 with a maximum peak reflow temperature of 250 °C-fully compatible with lead-free reflow profiles.
What package type does the TGL41-56-E3/96 use, and what are its key mechanical features?
The TGL41-56-E3/96 uses the DO-213AB (GL41) plastic MELF package-a cylindrical, axial-leaded outline with solderable matte tin-plated ends. Key mechanical features include UL 94 V-0 flammability rating, glass passivation for junction stability, and a blue band marking the cathode. Its dimensions are D1 = 0.095–0.105 inches (2.41–2.67 mm) diameter and overall length ~0.238 inches (6.0 mm).
