Product details
Overview
TGL41-36-E3/97 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-213AB (GL41) plastic MELF package, designed for clamping voltage transients on signal and power lines. It features 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), 8.0 A peak pulse current (IPPM), and 49.9 V clamping voltage (VC) at rated surge - used in sensor interface protection and MOSFET gate drive circuits.
For engineers reviewing the TGL41-36-E3/97 datasheet, TGL41-36-E3/97 pinout, TGL41-36-E3/97 application, or TGL41-36-E3/97 equivalent, key selection criteria include unidirectional polarity, DO-213AB mechanical compatibility, 150 °C max junction temperature, 1.0 W steady-state power dissipation, and compliance with J-STD-020 MSL level 1 handling requirements.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band, enabling forward-biased conduction during overvoltage events on positive-going transients. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance for consistent clamping performance under repetitive 0.01% duty cycle surges.
The device delivers fast response time (<1 ns) and low clamping ratio (VC/VWM ≈ 1.63), making it suitable for protecting sensitive CMOS inputs and analog front-ends against ESD and inductive switching spikes. Thermal derating follows a linear curve above 25 °C ambient, maintaining 1.0 W dissipation only up to 75 °C lead temperature on infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines minimum voltage at which device enters avalanche conduction; critical for ensuring clamping initiates above normal operating voltage |
| VWM | 30.8 V - maximum continuous reverse working voltage before leakage exceeds 5 μA; sets upper limit for safe DC bias operation |
| VC @ IPPM | 49.9 V - clamped voltage during 8.0 A transient; determines worst-case overvoltage seen by protected circuit |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 μs waveform; defines surge energy absorption capacity |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine); supports robustness against short-duration inrush currents |
| TJ max. | 150 °C - maximum junction temperature; constrains thermal design margin and PCB copper area requirements |
| Package | DO-213AB (GL41) - cylindrical plastic MELF outline with solderable matte tin-plated ends; compatible with automated pick-and-place |
Pinout & Package
DO-213AB (GL41) is a two-terminal axial plastic MELF package with cathode identified by a blue band. The device has no internal pins; terminals are solderable ends of the cylindrical body, with cathode end designated as positive relative to anode during transient suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient current sink | Connected to protected line; conducts avalanche current to ground during overvoltage, requiring low-inductance grounding path |
| Anode (opposite end) | Reference return | Typically tied to system ground or lower-potential rail; completes current path during clamping event |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR over temperature and lifetime, minimizing drift in clamping threshold across industrial operating range |
| MSL Level 1 (J-STD-020) | Enables standard SMT reflow without moisture sensitivity concerns; eliminates bake requirement prior to assembly |
| 400 W peak pulse power (10/1000 μs) | Provides sufficient energy absorption for IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge testing on 24 V control lines |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes overvoltage stress on downstream ICs while maintaining margin above VWM for reliable standby operation |
| Uni-directional polarity only | Simplifies layout for DC-biased lines (e.g., sensor supply rails), avoiding bidirectional capacitance penalty on high-speed signals |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module Inputs |
|---|---|
Use Scenario: Protecting 3.3 V/5 V analog sensor outputs (e.g., pressure, temperature) from load dump and relay coil flyback in factory automation systems. IC Role / Device Role / Timing Role: Transient voltage suppressor placed between sensor output and microcontroller ADC input, clamping spikes within 1 ns.

IC Role / Device Role / Timing Role: TVS connected between gate and source to clamp dv/dt-induced overshoot exceeding VGS(max). Use Value: Maintains gate oxide integrity by clamping transients to ≤49.9 V with sub-nanosecond response, avoiding unintended turn-on. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ33A | DO-214AA (SMB) package; 33 V VWM, 53.3 V VC at 7.5 A; 600 W PPPM | Higher clamping voltage and larger footprint; better suited for higher-energy surges where board space allows | Select when higher surge margin is needed and MELF placement is not required |
| P6SMB33A | Same DO-214AA package as SMBJ33A but with tighter VBR tolerance (5% vs. 10%); identical electrical specs | No functional difference in clamping behavior; differs only in manufacturing consistency and screening | Prefer for automotive-grade designs requiring tighter parametric control |
Compared with TGL41-36-E3/97, SMBJ33A offers higher surge rating but requires PCB redesign due to SMB footprint, while P6SMB33A provides identical protection with enhanced VBR consistency - both lack the MELF form factor's automated placement advantage and thermal profile.

FAQ
What is the polarity configuration of the TGL41-36-E3/97?
The TGL41-36-E3/97 is a unidirectional TVS diode with cathode identified by a blue band on the device body. During normal operation, the cathode is held at a higher potential than the anode; it conducts only when reverse voltage exceeds the breakdown threshold. This configuration makes TGL41-36-E3/97 appropriate for DC-biased lines where polarity is fixed, such as sensor supply rails or regulated power outputs.
Does the TGL41-36-E3/97 meet JEDEC moisture sensitivity requirements?
Yes, the TGL41-36-E3/97 meets J-STD-020 MSL Level 1, meaning it has unlimited floor life and can undergo standard reflow soldering without pre-baking. This is confirmed in the Vishay datasheet (Document Number 88403, Revision 11-Dec-12) and applies to the E3 suffix variant, which uses matte tin-plated leads and complies with JESD 22-B102 solderability standards.
What is the clamping voltage of the TGL41-36-E3/97 at its rated peak pulse current?
The TGL41-36-E3/97 has a maximum clamping voltage (VC) of 49.9 V at its rated peak pulse current (IPPM) of 8.0 A, measured using a 10/1000 μs waveform. This value represents the worst-case voltage imposed on the protected circuit during a full-rated surge event and is critical for verifying that downstream components remain within their absolute maximum ratings.
Can the TGL41-36-E3/97 be used in bidirectional signal lines like RS-485?
No, the TGL41-36-E3/97 is unidirectional only and is not suitable for bidirectional AC-coupled or differential signal lines such as RS-485. Its single-junction construction conducts only in one direction, so it cannot suppress negative-going transients on such lines. For bidirectional protection, a dedicated bidirectional TVS (e.g., TGL41-36CA) or back-to-back diode configuration would be required instead of TGL41-36-E3/97.
What is the steady-state power dissipation rating for the TGL41-36-E3/97?
The TGL41-36-E3/97 has a maximum steady-state power dissipation (PD) of 1.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C. This rating assumes ideal thermal conditions; actual usable power must be derated per Figure 5 in the Vishay datasheet (Document Number 88403) based on ambient temperature and PCB copper area, and does not apply during transient events where energy is absorbed capacitively.
