Product details
Overview
TGL41-22A-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), 20.9–23.1 V breakdown voltage, and 30.6 V clamping voltage at 13.1 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the TGL41-22A-E3/96 datasheet, TGL41-22A-E3/96 pinout, TGL41-22A-E3/96 application, or TGL41-22A-E3/96 equivalent, key selection criteria include unidirectional polarity, DO-213AB package compatibility, 18.8 V stand-off voltage, 5.0 μA max reverse leakage at VWM, and thermal derating above 25 °C.
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 capability with 3.5 V max forward voltage at 25 A, enabling robust protection of DC-biased signal and power lines.
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 0.095 %/°C temperature coefficient of VBR ensures stable clamping behavior under thermal variation in embedded power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 20.9 V / 23.1 V - defines minimum voltage at which clamping initiates reliably under 1.0 mA test current |
| VWM | 18.8 V - maximum continuous working voltage before leakage exceeds 5.0 μA |
| VC @ IPPM | 30.6 V - clamped voltage seen by protected circuit during 13.1 A transient (10/1000 μs) |
| PPPM | 400 W - peak transient energy absorption capacity without failure (duty cycle ≤0.01 %) |
| IFSM | 40 A - surge withstand capability for 8.3 ms half-sine waveform, critical for inrush and fault events |
| TJ max | +150 °C - maximum junction temperature enabling operation in high-ambient industrial environments |
| Polarity | Unidirectional - cathode marked with blue band; conducts forward like rectifier, blocks reverse until VBR |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical glass-body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal during normal TVS operation); 0.105"–0.095" diameter, 0.238" length; RoHS-compliant, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point in forward bias; grounded or low-side reference in protection topology | Connects to system ground or return path; must handle 40 A surge without bond-wire fusing |
| Cathode (blue band end) | Transient voltage sensing node; clamps when reverse voltage exceeds VBR | Connects to protected line (e.g., 24 V rail); absorbs energy by avalanching at 20.9–23.1 V |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated planar junction | Enables <1 ns response time and stable VBR tolerance over lifetime vs. epoxy-encapsulated alternatives |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-ground) in compact DO-213AB footprint |
| MSL Level 1 moisture sensitivity | Allows direct placement on PCB without baking; compatible with standard SMT reflow profiles up to 250 °C peak |
| 0.095 %/°C VBR tempco | Ensures ±3 % VBR shift over -40 °C to +125 °C ambient, maintaining margin above 18.8 V VWM |
| UL 94 V-0 molding compound | Prevents flame propagation during catastrophic failure, meeting IPC-7095B requirements for power electronics |
Applications
| Industrial Motor Drives | Programmable Logic Controllers (PLCs) |
|---|---|
Use Scenario: Protection of 24 V DC control inputs against back-EMF from solenoid valves and relay coils. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input terminal and ground to clamp inductive kick to ≤30.6 V.

IC Role / Device Role / Timing Role: Cathode tied to LIN line; anode to chassis ground-clamps negative-going spikes below -30.6 V and positive surges above 30.6 V. Use Value: Meets ISO 7637-2 Pulse 1 & 2 immunity requirements without adding series impedance to the bus. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA22A-E3/54 | Same VBR range (20.9–23.1 V), but SMA package (DO-214AC); 400 W rating, 30.6 V VC; higher thermal resistance (RθJA ≈ 110 °C/W vs. ~75 °C/W for GL41) | Suitable for board space-constrained designs where MELF placement is impractical; less optimal for high-reliability automated optical inspection due to lack of end-band marking | Select P4SMA22A-E3/54 when using standard SMT pick-and-place with vision alignment; prefer TGL41-22A-E3/96 for high-volume MELF-compatible lines with proven yield. |
| SMAJ22A | Identical electrical specs (VBR, VC, PPPM), SMA package; no MSL Level 1 rating-requires baking prior to reflow; higher leakage (10 μA vs. 5 μA at VWM) | Better suited for prototyping or low-volume builds where moisture sensitivity is managed manually; not recommended for automotive AEC-Q200-compliant production | Choose SMAJ22A only for non-automated assembly or legacy reflow processes; TGL41-22A-E3/96 offers superior process robustness and lower leakage for industrial-grade reliability. |
Compared with P4SMA22A-E3/54 and SMAJ22A, the TGL41-22A-E3/96 delivers lower thermal resistance, guaranteed MSL Level 1 handling, and tighter reverse leakage-critical for long-life industrial controllers where field failure modes must be minimized.

FAQ
What is the clamping voltage of the TGL41-22A-E3/96 under peak pulse conditions?
The TGL41-22A-E3/96 has a maximum clamping voltage (VC) of 30.6 V when subjected to its rated peak pulse current of 13.1 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected circuits remain below critical voltage thresholds during surge events. The TGL41-22A-E3/96 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-22A-E3/96 suitable for new designs despite Vishay's "Not For New Designs" notice?
The "Not For New Designs" designation applies to the entire TGL41 family and indicates Vishay recommends newer alternatives like the P4SMA series for future projects. However, the TGL41-22A-E3/96 remains fully supported, in active production, and appropriate for sustaining engineering, legacy system repair, and programs with validated qualification data. The TGL41-22A-E3/96 continues to meet all published specifications and reliability standards.
How does the GL41 (DO-213AB) package of the TGL41-22A-E3/96 compare to SMA in thermal performance?
The GL41 (DO-213AB) package used by the TGL41-22A-E3/96 offers lower junction-to-ambient thermal resistance (~75 °C/W) than standard SMA packages (~110 °C/W), enabling higher sustained power dissipation in confined layouts. Its cylindrical MELF geometry also supports automated optical inspection via end-band detection. The TGL41-22A-E3/96 leverages this for improved thermal margin in high-density industrial PCBs.
What is the meaning of the "E3/96" suffix in TGL41-22A-E3/96?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads qualified to JESD 201 Class 1A whisker testing. The "/96" indicates packaging in 7-inch plastic tape-and-reel format with 1500 units per reel. This configuration ensures compatibility with high-speed SMT placement equipment and traceable lot control. The TGL41-22A-E3/96 is supplied exclusively in this reel format.
Does the TGL41-22A-E3/96 support bidirectional transient suppression?
No, the TGL41-22A-E3/96 is unidirectional only, with a blue band marking the cathode. It clamps positive transients relative to ground and conducts forward current like a rectifier. For bidirectional protection, two devices would be required in series opposition-or a dedicated bidirectional TVS such as the P4SMA22CA-E3/54. The TGL41-22A-E3/96 is optimized for DC-biased lines where polarity is fixed.
