Product details
Overview
TGL41-170A-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), 162–179 V breakdown voltage (VBR), and 145 V stand-off voltage (VWM). It protects MOSFETs and signal lines in industrial sensor units against inductive switching transients.
For engineers reviewing the TGL41-170A-E3/97 datasheet, TGL41-170A-E3/97 pinout, TGL41-170A-E3/97 application, or TGL41-170A-E3/97 equivalent, key selection criteria include clamping voltage (234 V at IPPM), low incremental surge resistance, fast response time, and unidirectional polarity with blue-band cathode marking.
Technical Context
This TVS diode employs a glass-passivated planar junction optimized for high-reliability transient suppression in DC-biased circuits. Its unidirectional configuration provides forward conduction capability up to 40 A surge current (8.3 ms half-sine), while maintaining 1.0 W steady-state power dissipation on infinite heatsink at 75 °C.
The device operates across -55 °C to +150 °C junction temperature range and meets J-STD-020 MSL Level 1 (peak reflow ≤ 250 °C). Its 0.111 %/°C temperature coefficient of VBR ensures predictable voltage drift under thermal stress in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V - defines minimum clamping threshold and maximum guaranteed breakdown spread at 1.0 mA test current |
| VWM | 145 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA |
| VC @ IPPM | 234 V - clamped voltage during 400 W transient, limiting downstream IC stress |
| IPPM | 0.85 A - peak pulse current capability under 10/1000 μs waveform |
| PPPM | 400 W - transient energy absorption capacity per single pulse, duty cycle limited to 0.01 % |
| TJ max. | +150 °C - maximum junction temperature enabling operation in high-ambient industrial enclosures |
| Polarity | Unidirectional - allows forward conduction; cathode marked by blue band |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical glass-body diode with solderable matte tin-plated ends, 0.105–0.095 inch (2.67–2.41 mm) diameter, 0.238 inch (6.0 mm) length. Blue band denotes cathode (positive terminal under normal TVS operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground or low-side reference | Enables bidirectional surge path when used with complementary circuitry; must be routed with low-inductance trace |
| Cathode (blue band) | Current exit point in forward bias; connected to protected line or positive rail | Defines polarity-sensitive placement-reversal causes failure to clamp transients on protected node |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Supports robust protection against IEC 61000-4-5 Level 4 surges without derating in compact MELF form factor |
| Glass-passivated planar junction | Ensures stable VBR tolerance and low leakage (<5 μA at VWM) over 150 °C lifetime operation |
| MSL Level 1 compliance | Enables direct placement into standard SMT reflow profiles without pre-baking |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., relay bounce, motor commutation) |
| Matte tin-plated terminals | Guarantees solderability per J-STD-002 and JESD 22-B102, eliminating whisker risk (JESD 201 Class 1A) |
Applications
| Industrial Motor Control | Telecom Power Supply Protection |
|---|---|
Use Scenario: Suppressing inductive kickback from 24 V DC solenoids and contactors in PLC I/O modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA150A-E3/97 | Same DO-214AC (SMA) package; 150 V VWM, 219 V VC; lower 400 W rating but higher IPPM (0.97 A) | Requires PCB footprint change; better suited for space-constrained layouts needing surface-mount flat geometry | Select when board real estate limits MELF placement or when automated optical inspection favors rectangular package |
| SMBJ150A | DO-214AA (SMB) package; 150 V VWM, 243 V VC; 600 W PPPM but larger footprint and higher VC | Higher clamping voltage reduces protection margin for 150 V systems; requires thermal relief on pads due to 2.0 W PD | Choose only if system-level testing confirms 243 V clamping is acceptable and layout accommodates 3.5 mm × 3.5 mm outline |
Compared with P4SMA150A-E3/97 and SMBJ150A, the TGL41-170A-E3/97 offers superior thermal performance in MELF form (MSL Level 1, no pre-bake), tighter VBR tolerance (±5.2 %), and lower leakage-making it preferred for high-reliability industrial and telecom deployments where long-term stability matters more than footprint size.

FAQ
What is the clamping voltage of the TGL41-170A-E3/97 under peak pulse conditions?
The TGL41-170A-E3/97 has a maximum clamping voltage (VC) of 234 V when subjected to its rated peak pulse current (IPPM = 0.85 A) using a 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during transient events. The TGL41-170A-E3/97 maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is the TGL41-170A-E3/97 suitable for new designs?
No-the TGL41-170A-E3/97 is marked "Not For New Designs" in Vishay's official documentation (Revision 14-Nov-2023, Doc. #88403), with P4SMA150A-E3/97 cited as the recommended alternative. While fully functional and supported for existing production, Aetrix Electronics advises new designs to evaluate the P4SMA series for long-term supply assurance. The TGL41-170A-E3/97 remains available for legacy program continuity and repair.
What does the "E3/97" suffix indicate in TGL41-170A-E3/97?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards; "/97" specifies packaging in 13-inch plastic tape and reel with 5000 units per reel. This format ensures compatibility with high-speed pick-and-place equipment and satisfies JESD 201 Class 1A whisker resistance requirements. The TGL41-170A-E3/97 uses the same E3/97 designation across the full TGL41 family for consistent procurement handling.
How does the GL41 (DO-213AB) package of the TGL41-170A-E3/97 compare to SMA/SMB packages in thermal performance?
The GL41 (DO-213AB) MELF package of the TGL41-170A-E3/97 delivers superior thermal resistance versus flat-pack alternatives: its cylindrical geometry enables uniform heat distribution and achieves 1.0 W power dissipation at TL = 75 °C on an infinite heatsink-matching SMA's rating while offering MSL Level 1 reflow compatibility (250 °C peak) without pre-baking. Unlike SMA/SMB, the TGL41-170A-E3/97 avoids thermal pad voiding risks and supports automated optical alignment. The TGL41-170A-E3/97 thus excels in thermally demanding, high-reliability applications where process robustness is critical.
Can the TGL41-170A-E3/97 be used in bidirectional transient protection circuits?
No-the TGL41-170A-E3/97 is specified for unidirectional operation only, with polarity indicated by a blue band marking the cathode. Bidirectional protection requires either two back-to-back unidirectional devices or a dedicated bidirectional TVS (e.g., TGL41-170CA). Using the TGL41-170A-E3/97 in reverse-biased configurations will not provide clamping on negative transients and may lead to catastrophic failure. Designers must verify polarity alignment during layout; the TGL41-170A-E3/97 functions correctly only when cathode connects to the protected line and anode to reference ground.
