Product details
Overview
TGL41-9.1A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) plastic MELF package, with 8.65 V to 9.55 V breakdown voltage (VBR), 7.78 V stand-off voltage (VWM), and 400 W peak pulse power (10/1000 μs). It clamps transients to ≤13.4 V at 29.9 A peak pulse current and is used for protecting MOSFETs and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-9.1A-E3/96 datasheet, TGL41-9.1A-E3/96 pinout, TGL41-9.1A-E3/96 application, or TGL41-9.1A-E3/96 equivalent, key selection criteria include unidirectional polarity, 1.0 mA test current, 50 μA max reverse leakage at VWM, 150 °C max junction temperature, and DO-213AB mechanical compatibility with automated placement systems.
Technical Context
This TVS diode employs a glass-passivated planar junction for stable breakdown characteristics and low incremental surge resistance. Its unidirectional configuration provides forward conduction only during positive transients relative to cathode, with a blue band marking the cathode terminal.
The device operates within -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. It delivers 400 W peak pulse power at 25 °C, derating linearly above that ambient per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V - Ensures reliable triggering above circuit's normal operating voltage while avoiding false clamping. |
| VWM | 7.78 V - Maximum continuous reverse voltage before significant leakage; sets safe operating margin below VBR. |
| IPPM | 29.9 A - Peak transient current it can shunt without failure under 10/1000 μs waveform. |
| VC @ IPPM | 13.4 V - Clamped voltage seen by protected circuit during worst-case surge; defines protection level. |
| PPPM | 400 W - Surge energy handling capacity for single-event transients; critical for inductive load switching. |
| IR @ VWM | 50.0 μA - Low leakage preserves signal integrity and power efficiency in standby or low-power modes. |
| TJ max | +150 °C - Enables use in high-temperature environments such as enclosed industrial enclosures or near power stages. |
Pinout & Package
Package: GL41 (DO-213AB) - hermetically sealed plastic MELF case with matte tin-plated leads, RoHS-compliant (E3 suffix), MSL Level 1, UL 94 V-0 rated molding compound. Cathode identified by blue band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to ground or lower-potential rail; absorbs negative-going transients when used in unidirectional configuration. |
| Cathode (blue band) | Transient current sink | Connected to protected line (e.g., sensor output); conducts surge current to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated planar junction | Ensures stable VBR tolerance and long-term reliability under repeated surge stress. |
| 400 W peak pulse power (10/1000 μs) | Handles high-energy transients from relay coil decay or lightning-induced surges in telecom interfaces. |
| Low clamping ratio (VC/VBR ≈ 1.41) | Minimizes voltage overshoot on protected ICs, reducing risk of latch-up or gate oxide damage. |
| MSL Level 1, 250 °C peak reflow | Supports standard lead-free SMT assembly without preconditioning or special handling. |
| Automated placement compatible | DO-213AB geometry enables high-speed pick-and-place with standard MELF feeders and vision alignment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA9.1A-E3/96 | Same VBR range (8.65–9.55 V), but SMA package (DO-214AC); 400 W rating, 1.0 W steady-state dissipation. | SMA offers higher board-level robustness and easier manual rework; less suitable for ultra-high-density MELF layouts. | Select P4SMA9.1A-E3/96 if PCB space allows larger footprint and hand-soldering or field repair is required. |
| SMAJ9.0A | VBR min/max = 8.55–9.45 V; same DO-214AC package; identical 400 W rating but slightly tighter VBR tolerance. | Designed for broader industrial temperature range (-65 °C to +150 °C); not MELF-formatted for automated placement. | Choose SMAJ9.0A where extended cold-start operation or legacy SMA footprint compatibility is mandatory. |
Compared with P4SMA9.1A-E3/96 and SMAJ9.0A, the TGL41-9.1A-E3/96 uniquely supports high-volume automated placement via its DO-213AB MELF form factor while maintaining identical electrical protection specs-making it optimal for compact, high-throughput consumer and telecom assemblies.

FAQ
What is the breakdown voltage range for TGL41-9.1A-E3/96?
The TGL41-9.1A-E3/96 has a guaranteed breakdown voltage (VBR) range of 8.65 V to 9.55 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This range ensures predictable turn-on behavior while accommodating process variation, and is validated across the full -55 °C to +150 °C operating temperature range. The TGL41-9.1A-E3/96 maintains this specification without derating up to 125 °C junction temperature.
Is TGL41-9.1A-E3/96 suitable for bidirectional transient protection?
No, the TGL41-9.1A-E3/96 is unidirectional only, with cathode marked by a blue band and designed to conduct only when the cathode is positive relative to the anode. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ9.0CA must be selected instead of the TGL41-9.1A-E3/96.
What is the maximum clamping voltage of TGL41-9.1A-E3/96 under surge conditions?
The TGL41-9.1A-E3/96 clamps to a maximum of 13.4 V at its rated peak pulse current of 29.9 A (10/1000 μs waveform). This value is specified in the Electrical Characteristics table and confirmed by standardized surge testing per IEC 61000-4-5. The TGL41-9.1A-E3/96 achieves this clamping performance with minimal voltage overshoot due to its low dynamic impedance and fast response time.
Does TGL41-9.1A-E3/96 meet RoHS and lead-free assembly requirements?
Yes, the TGL41-9.1A-E3/96 carries the E3 suffix indicating RoHS compliance and commercial-grade qualification. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it is rated for lead-free reflow with a maximum peak temperature of 250 °C (MSL Level 1 per J-STD-020). The TGL41-9.1A-E3/96 also passes JESD 201 Class 1A whisker testing.
Can TGL41-9.1A-E3/96 replace TGL41-9.1A without changes?
Yes, the TGL41-9.1A-E3/96 is a direct replacement for TGL41-9.1A, differing only in packaging format (E3 denotes RoHS-compliant tape-and-reel delivery mode) and not in electrical or mechanical specifications. Both share identical GL41 (DO-213AB) package dimensions, VBR, VC, and surge ratings. The TGL41-9.1A-E3/96 maintains full form-fit-function compatibility with legacy TGL41-9.1A designs.
