Product details
Overview
TGL41-170A-E3/96 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-E3/96 datasheet, TGL41-170A-E3/96 pinout, TGL41-170A-E3/96 application, or TGL41-170A-E3/96 equivalent, key selection criteria include clamping voltage (234 V at 0.85 A IPPM), unidirectional polarity with blue-band cathode marking, and MSL Level 1 moisture sensitivity per J-STD-020.
Technical Context
This TVS diode uses a glass-passivated planar junction to achieve fast response time (<1 ns) and low incremental surge resistance, enabling effective clamping of transient overvoltages before downstream ICs are damaged. Its DO-213AB package supports automated placement and meets UL 94 V-0 flammability requirements.
The device operates across -55 °C to +150 °C junction temperature range and delivers 1.0 W steady-state power dissipation on an infinite heatsink at 75 °C. It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits a VBR temperature coefficient of 0.111 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 162 V / 179 V - defines minimum voltage at which TVS enters avalanche conduction under 1.0 mA test current |
| VWM | 145 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| VC @ IPPM | 234 V - clamped voltage during 0.85 A peak pulse (10/1000 μs), limiting stress on protected circuitry |
| PPPM | 400 W - peak pulse power handling capability under standard 10/1000 μs waveform, 0.01% duty cycle |
| IFSM | 40 A - maximum non-repetitive forward surge current (8.3 ms half-sine), critical for inductive load protection |
| TJ max. | +150 °C - maximum junction temperature, defining thermal derating limits in high-ambient designs |
| Polarity | Unidirectional - cathode marked by blue band; conducts only in reverse-biased avalanche mode |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal under normal TVS operation). No discrete pins - two axial terminals with symmetric geometry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; grounded reference in typical TVS placement | Connected to system ground or low-impedance return path to absorb transient energy into GND |
| Cathode (blue-band end) | Avalanche conduction terminal in reverse bias; clamps voltage relative to anode | Connected to protected line (e.g., sensor output); clamps to ≤234 V when transients exceed 145 V |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against high-energy transients common in industrial motor drives and relay coils |
| Glass-passivated planar junction | Ensures stable VBR tolerance (±5%), low leakage (<5 μA at VWM), and long-term reliability under thermal cycling |
| MSL Level 1 (250 °C peak reflow) | Supports standard lead-free SMT assembly without pre-baking or special handling |
| UL 94 V-0 compliant molding compound | Meets flame-retardancy requirements for safety-critical industrial and telecom equipment enclosures |
| Automated placement compatibility | DO-213AB geometry enables high-speed pick-and-place with standard MELF feeders and vision alignment |
Applications
| Industrial Sensor Signal Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) of pressure/temperature sensors mounted near AC motors or solenoids. IC Role / Device Role / Timing Role: TVS clamping element placed between signal line and ground, absorbing inductive kickback spikes before they reach ADC input or isolation amplifier. Use Value: Limits transient voltage to ≤234 V, preventing latch-up or damage to precision op-amps rated for ±36 V absolute maximum ratings. |
Use Scenario: Shielding RS-485 transceiver data lines in outdoor base station cabinets exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Primary overvoltage clamp on differential bus lines (A/B), referenced to local ground plane with low-inductance layout. Use Value: Responds in <1 ns to clamp 1 kV/μs transients, preserving signal integrity while maintaining <5 pF junction capacitance at zero bias. |
| MOSFET Gate Driver Protection | Computer Peripheral Port Protection |
Use Scenario: Safeguarding high-side N-channel MOSFET gate drive traces in DC-DC synchronous buck converters subject to shoot-through-induced voltage reversal. IC Role / Device Role / Timing Role: Unidirectional TVS tied between gate and source, suppressing negative-going undershoot below -0.7 V and positive overshoot above VGS(max). Use Value: Clamps gate-source voltage to ≤234 V while allowing normal 12 V gate drive swing, avoiding unintended turn-on or oxide breakdown. |
Use Scenario: Adding secondary surge immunity to USB 2.0 D+/D− lines in embedded host controllers used in factory automation HMIs. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to connector, shunting ESD events (IEC 61000-4-2 Level 4) to chassis ground. Use Value: Adds <5 pF parasitic capacitance to maintain USB full-speed signal rise/fall times, while surviving 15 kV contact discharge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA170A-E3/96 | Same VWM (145 V) and VC (234 V), but SMA package (DO-214AC); 600 W PPPM; higher IPPM (1.0 A) | SMA offers larger thermal mass and easier manual rework; less suitable for ultra-compact MELF layouts | Select when board space allows larger footprint and higher pulse energy margin is required |
| SMAJ170A-E3/52 | Same DO-214AC package as P4SMA; lower PPPM (400 W), identical VBR/VC; RoHS-compliant, commercial grade | Designed for cost-sensitive consumer applications; not rated for extended industrial temperature range | Select for non-critical environments where TJ = 125 °C max suffices and MELF placement is not required |
Compared with TGL41-170A-E3/96, P4SMA170A-E3/96 provides higher pulse energy headroom in a surface-mount package with greater thermal dissipation, while SMAJ170A-E3/52 offers a lower-cost alternative with reduced temperature rating and no MELF placement compatibility.

FAQ
What is the clamping voltage of the TGL41-170A-E3/96 under peak pulse conditions?
The TGL41-170A-E3/96 has a maximum clamping voltage (VC) of 234 V when subjected to its rated peak pulse current (IPPM) of 0.85 A using a 10/1000 μs waveform. This value is measured at the device terminals and ensures downstream components see voltage limited to this level during transient events.
Is the TGL41-170A-E3/96 suitable for new designs?
No - Vishay explicitly marks the TGL41-170A-E3/96 as "Not For New Designs" in its official documentation (Document Number 88403, Revision 14-Nov-2023). Engineers developing new products should consider approved alternatives such as the P4SMA170A-E3/96 or SMAJ170A-E3/52.
What does the "E3/96" suffix indicate in TGL41-170A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction meeting JESD 201 Class 1A whisker testing; "/96" specifies packaging in 7-inch diameter plastic tape and reel, with a base quantity of 1500 units per reel - optimized for automated SMT assembly lines.
How is polarity identified on the TGL41-170A-E3/96?
The TGL41-170A-E3/96 uses a blue band to mark the cathode terminal, which is the positive side under normal TVS operation (reverse-biased clamping mode). The unmarked end is the anode. This marking aligns with industry-standard MELF polarity identification per DO-213AB mechanical drawings.
What is the maximum operating junction temperature for the TGL41-170A-E3/96?
The TGL41-170A-E3/96 has a maximum junction temperature (TJ) rating of +150 °C, as specified in Vishay's datasheet. Derating of peak pulse power begins above 25 °C ambient, following the curve in Figure 2 of Document Number 88403.
