Product details
Overview
TGL41-51A-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), 48.5–53.6 V breakdown voltage, and 70.1 V clamping voltage at 5.7 A peak pulse current. It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-51A-E3/97 datasheet, TGL41-51A-E3/97 pinout, TGL41-51A-E3/97 application, or TGL41-51A-E3/97 equivalent, key selection criteria include unidirectional polarity, 43.6 V stand-off voltage, 5.0 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining high impedance under normal operation up to 43.6 V.
The device operates within -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (peak reflow 250 °C). It delivers 400 W peak pulse power at 25 °C, derating linearly above TA = 25 °C per published curve, with 200 W rating above 91 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 48.5 V / 53.6 V - ensures reliable triggering above system operating voltage with margin against tolerance drift |
| VWM | 43.6 V - maximum continuous reverse working voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 70.1 V - clamping voltage seen by protected circuit during 5.7 A transient event |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform at 0.01% duty cycle |
| IFSM | 40 A - non-repetitive forward surge current rating for 8.3 ms half-sine wave |
| Junction Temp | -55 °C to +150 °C - enables use in harsh industrial environments without thermal derating penalties |
| Package | GL41 (DO-213AB) - compact MELF outline optimized for high-density automated placement and reflow soldering |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with two solderable axial leads. The blue band denotes the cathode terminal, which is positive with respect to the anode during TVS conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode | Reference return path | Typically tied to system ground or low-impedance return plane for effective clamping |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power | Enables robust protection of 24 V and 48 V industrial bus lines against IEC 61000-4-5 Level 3 surges |
| Glass-passivated junction | Ensures stable VBR and low leakage over lifetime, even under humidity and thermal cycling stress |
| MSL Level 1 rating | Supports single-reflow assembly without moisture sensitivity concerns or baking requirements |
| Matte tin-plated leads | Guarantees solderability per J-STD-002 and JESD 22-B102, compatible with lead-free and SnPb processes |
| Unidirectional polarity only | Simplifies layout in DC-biased circuits where reverse conduction is not required |
Applications
| Industrial Sensor Signal Protection | 48 V DC Power Rail Clamping |
|---|---|

| Telecom Line Interface Protection | Automated Test Equipment (ATE) I/O Guarding |
|
Use Scenario: Shielding RS-485 transceiver data lines in base station remote radio units from lightning-induced surges on outdoor cabling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA51A-E3/97 | Same 51 V nominal breakdown, but SMA package (DO-214AC); 400 W rating, 70 V clamping, 5.7 A IPPM | Surface-mount flat lead package requires different PCB footprint and thermal relief design | Select when board space allows larger body size and higher thermal mass is preferred over MELF density |
| SMAJ51A | DO-214AC package; identical electrical specs (VBR: 48.5–53.6 V, VC: 70.1 V), but lower surge current rating (5.6 A vs. 5.7 A) | Compatible with standard SMA footprints but lacks MELF's automated placement yield advantage | Choose for legacy designs already using SMA packages or where MELF placement equipment is unavailable |
Compared with P4SMA51A-E3/97 and SMAJ51A, the TGL41-51A-E3/97 offers superior placement efficiency in high-volume manufacturing due to its MELF geometry and JEDEC-compliant tape-and-reel packaging (5000 pcs/reel), while delivering identical clamping performance and thermal robustness in compact form factor.

FAQ
What is the clamping voltage of the TGL41-51A-E3/97 under peak pulse conditions?
The TGL41-51A-E3/97 has a maximum clamping voltage (VC) of 70.1 V at 5.7 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 TGL41-51A-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-51A-E3/97 suitable for new designs?
No - Vishay explicitly marks the TGL41-51A-E3/97 as "Not For New Designs" in its official documentation, citing the P4SMA series as the recommended alternative. Engineers designing new products should evaluate P4SMA51A-E3/97 or SMAJ51A instead. The TGL41-51A-E3/97 remains supported for existing production and legacy BOM continuity.
What does the "E3/97" suffix indicate in TGL41-51A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 22-B102 whisker resistance (Class 1A). The "/97" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units per reel - optimized for high-volume SMT assembly lines.
How does the GL41 (DO-213AB) package affect thermal performance of the TGL41-51A-E3/97?
The GL41 (DO-213AB) MELF package provides moderate thermal resistance due to its small cylindrical geometry and axial lead configuration. The TGL41-51A-E3/97 is rated for 1.0 W power dissipation on an infinite heatsink at TL = 75 °C. In practice, thermal performance depends heavily on PCB copper area and via count beneath mounting pads; no internal thermal pad exists, so external copper acts as primary heat path.
What is the reverse leakage current specification for the TGL41-51A-E3/97 at its stand-off voltage?
The TGL41-51A-E3/97 specifies a maximum reverse leakage current (ID) of 5.0 μA at its stand-off voltage (VWM) of 43.6 V, measured at 25 °C. This low leakage ensures minimal power loss and signal interference in always-on monitoring circuits such as sensor outputs or communication lines. The TGL41-51A-E3/97 maintains this spec across its full operating temperature range.
