Product details
Overview
TGL41-27-E3/97 from Vishay General Semiconductor is a unidirectional TransZorb® transient voltage suppressor diode in DO-213AB (GL41) plastic MELF package, rated for 400 W peak pulse power (10/1000 μs), 25.7–28.4 V breakdown voltage, and 37.5 V clamping voltage at 10.7 A. It protects MOSFETs and ICs in power supply rails and sensor signal lines against inductive switching transients.
For engineers reviewing the TGL41-27-E3/97 datasheet, TGL41-27-E3/97 pinout, TGL41-27-E3/97 application, or TGL41-27-E3/97 equivalent, key selection criteria include unidirectional polarity, 23.1 V stand-off voltage, 5 μA max reverse leakage at VWM, 150 °C max junction temperature, and RoHS-compliant matte tin-plated terminals suitable for automated placement.
Technical Context
This TVS diode operates exclusively in unidirectional mode with a blue band marking the cathode. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for clamping sub-microsecond transients induced by relay or solenoid switching.
The DO-213AB (GL41) MELF package supports high thermal dissipation under pulsed conditions and meets J-STD-020 MSL Level 1 (peak reflow 250 °C). Derating curves confirm stable 400 W PPPM up to 91 V; above that, rating drops to 200 W - a hard limit confirmed for TGL41-27-E3/97 per its VBR range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 25.7 V / 28.4 V - defines minimum voltage at which device enters avalanche conduction; ensures reliable clamping above circuit operating voltage |
| VWM | 23.1 V - maximum continuous reverse working voltage; must exceed system's highest steady-state rail voltage |
| IPPM | 10.7 A - peak pulse current at 10/1000 μs waveform; determines minimum trace width and PCB layout robustness |
| VC | 37.5 V - clamped voltage at IPPM; sets upper bound on protected circuit's transient overvoltage stress |
| PPPM | 400 W - peak pulse power handling; validates suitability for 24 V industrial control bus protection |
| TJ max | 150 °C - maximum junction temperature; constrains ambient + power dissipation design margin in enclosed enclosures |
| IR @ VWM | 5 μA - reverse leakage at stand-off voltage; negligible loading on 24 V sensor bias networks |
Pinout & Package
DO-213AB (GL41) plastic MELF package: cylindrical glass-body diode with solderable matte tin-plated ends; cathode marked by blue band; no leads - terminals are axial end caps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction; grounded reference in unidirectional TVS configuration | Connected to system ground or low-impedance return path; establishes reference for clamping action |
| Cathode (blue band end) | Transient voltage sensing node; connected to protected line (e.g., 24 V rail or signal) | Acts as high-impedance monitor until VBR exceeded; then conducts surge current to anode/ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables <1 ns response time and stable VBR tolerance across temperature and life cycle |
| 400 W peak pulse power (10/1000 μs) | Supports robust protection of 24 V industrial I/O modules against IEC 61000-4-5 Level 3 surges |
| MSL Level 1 (250 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning or special handling |
| Uni-directional polarity only | Simplifies layout in DC-biased rails where reverse conduction is not required or desired |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance; qualified for long-life automotive and telecom deployments |
Applications
| Industrial PLC Digital Input Protection | Automotive Body Control Module (BCM) Power Rail |
|---|---|
Use Scenario: 24 V digital input channels in programmable logic controllers exposed to relay coil flyback and field wiring ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground to clamp transients before they reach optocoupler or MCU GPIO. Use Value: Clamps 1 kV/500 A surge (IEC 61000-4-5) to ≤37.5 V, preserving input stage integrity without adding capacitance-induced signal delay. | Use Scenario: 12 V/24 V power distribution to microcontrollers and CAN transceivers in body electronics. IC Role / Device Role / Timing Role: Primary overvoltage protector on main VBAT feed, upstream of LDOs and PMICs. Use Value: Absorbs load dump energy (ISO 7637-2 Pulse 5a) with 400 W capability and 150 °C TJ rating for under-hood thermal resilience. |
| Telecom Remote Sensor Interface | Consumer Appliance Motor Driver Stage |
Use Scenario: RS-485 or analog 4–20 mA loop-powered sensors deployed in outdoor cabinets subject to lightning-induced surges. IC Role / Device Role / Timing Role: First-line protection on signal line and power pair, paired with gas discharge tube (GDT) for staged suppression. Use Value: Low 5 μA leakage avoids loading precision current loops; 37.5 V clamping prevents op-amp saturation in front-end amplifiers. | Use Scenario: H-bridge gate driver supply rails in washing machine or HVAC blower motor control. IC Role / Device Role / Timing Role: Clamp inductive kickback from brushed DC motor commutation across VDD and ground. Use Value: Withstands repetitive 40 A IFSM surges and maintains stable VBR after >10⁵ pulses per MIL-STD-750 Method 2074. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | DO-214AA (SMB) package; 24 V VWM, 38.9 V VC at 10.3 A; 600 W PPPM | Higher power but larger footprint; requires PCB real estate and thermal relief not needed for MELF | Select when higher surge margin is required and board space allows SMB footprint |
| P6SMB27A | DO-214AA (SMB); 27 V VWM, 43.5 V VC at 9.2 A; 600 W PPPM; ±5 % VBR tolerance vs. TGL41-27-E3/97's ±5.2 % | Wider VC spread increases protected IC stress; less precise clamping than TGL41 series | Choose only if SMB form factor is mandated and tighter clamping is not critical |
Compared with SMBJ24A and P6SMB27A, the TGL41-27-E3/97 delivers superior clamping ratio (VC/VBR = 1.32) in a compact MELF package optimized for high-density automated assembly, while maintaining lower thermal resistance and tighter VBR consistency across production lots.

FAQ
What is the exact breakdown voltage range for TGL41-27-E3/97?
The TGL41-27-E3/97 has a guaranteed breakdown voltage (VBR) range of 25.7 V to 28.4 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range is confirmed in the official Vishay datasheet document number 88403, revision 11-Dec-12, and applies strictly to the TGL41-27-E3/97 variant - not extrapolated from adjacent part numbers.
Does TGL41-27-E3/97 support bidirectional transient suppression?
No, TGL41-27-E3/97 is unidirectional only, as explicitly stated in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It features a blue band marking the cathode and is designed for DC-biased circuits; bidirectional operation would require a symmetric device such as the SMBJ27CA, not the TGL41-27-E3/97.
What is the clamping voltage of TGL41-27-E3/97 at its rated peak pulse current?
The TGL41-27-E3/97 clamps to a maximum of 37.5 V at its rated peak pulse current (IPPM) of 10.7 A under the standard 10/1000 μs waveform. This value is measured and guaranteed per the Electrical Characteristics table in the Vishay datasheet 88403 and defines the upper voltage stress imposed on downstream circuitry during surge events.
Is TGL41-27-E3/97 compatible with lead-free reflow soldering processes?
Yes, TGL41-27-E3/97 is fully compatible with lead-free reflow. Its DO-213AB (GL41) package meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 250 °C, and its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards - all verified in the Vishay documentation for TGL41-27-E3/97.
What does the "E3/97" suffix indicate in TGL41-27-E3/97?
The "E3" suffix denotes RoHS-compliant construction and JESD 201 Class 1A whisker resistance; "/97" specifies packaging in 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This ordering code is defined in the Ordering Information section of the Vishay TGL41 datasheet and applies uniquely to the TGL41-27-E3/97 variant.
