Product details
Overview
TGL41-9.1A-E3/97 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 and is used for protecting MOSFETs and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the TGL41-9.1A-E3/97 datasheet, TGL41-9.1A-E3/97 pinout, TGL41-9.1A-E3/97 application, or TGL41-9.1A-E3/97 equivalent, key selection criteria include unidirectional polarity, 13.4 V clamping voltage at rated IPPM, DO-213AB mechanical compatibility, and RoHS-compliant matte tin-plated terminals meeting J-STD-002 solderability.
Technical Context
This TVS diode uses a glass-passivated planar junction for stable breakdown and low leakage (<50.0 μA at VWM). Its response time is sub-nanosecond, enabling protection against fast transients induced by inductive switching or ESD events.
The device operates over -55 °C to +150 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 250 °C lead-free reflow peak. Its 0.100 %/°C VBR temperature coefficient ensures predictable clamping across thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.65 V / 9.55 V - defines minimum voltage at which clamping initiates reliably under 1.0 mA test current |
| VWM | 7.78 V - maximum continuous reverse operating voltage before significant leakage begins |
| IPPM | 29.9 A - peak surge current it safely shunts during 10/1000 μs transient without failure |
| VC @ IPPM | 13.4 V - clamped voltage seen by protected circuit during full-rated surge event |
| PPPM | 400 W - transient energy absorption capability under standard 10/1000 μs waveform |
| TJ max. | +150 °C - maximum junction temperature defining thermal derating envelope for sustained operation |
| Leakage @ VWM | 50.0 μA - reverse leakage current at stand-off voltage, critical for low-power sensor line integrity |
Pinout & Package
GL41 (DO-213AB) plastic MELF package: cylindrical body with solderable matte tin-plated ends; blue band denotes cathode (positive terminal during clamping); no internal leads - terminals are the two axial ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Reference node for reverse-biased operation | Connected to ground or lower-potential rail; carries surge current into ground path during clamping |
| Cathode (blue band end) | Transient voltage sensing and clamping node | Connected to protected line (e.g., sensor output); conducts when line voltage exceeds VBR, limiting excursion to ≤13.4 V |
Key Features
| Feature | Design Value |
|---|---|
| Plastic MELF packaging | Enables high-volume automated placement and provides robust mechanical stability for board-level surge environments |
| Glass-passivated junction | Ensures low leakage (<50 μA) and long-term parameter stability under thermal cycling and humidity exposure |
| 400 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity without external series impedance |
| MSL Level 1 rating | Allows direct use in lead-free reflow processes up to 250 °C peak without preconditioning or dry-pack requirements |
| Unidirectional polarity only | Simplifies layout for DC-biased lines (e.g., 5 V/3.3 V sensor buses) where reverse conduction is not required |
Applications
| Industrial Motor Control | Automotive Sensor Interface |
|---|---|
Use Scenario: Protecting gate drivers and feedback signal lines from inductive kickback during relay or solenoid switching in PLC modules. IC Role / Device Role / Timing Role: TVS diode placed across MOSFET gate-source or op-amp input to clamp transients before they exceed absolute maximum ratings. Use Value: Limits voltage excursion to ≤13.4 V, preventing latch-up or oxide damage in 3.3 V/5 V control ICs while surviving repetitive 400 W pulses. | Use Scenario: Shielding analog outputs of pressure or temperature sensors connected to vehicle ECUs from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS mounted on sensor PCB output trace, referenced to chassis ground, absorbing 10/1000 μs surges up to 29.9 A. Use Value: Maintains signal integrity below 13.4 V clamping threshold, ensuring ADC input stays within safe range and avoiding false fault detection. |
| Telecom Power Supply Rails | Consumer USB Data Lines |
Use Scenario: Safeguarding 12 V/24 V DC-DC converter inputs in base station power modules against lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-line TVS placed upstream of input filter capacitor, conducting surge energy directly to system ground.

IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS (CJ < 100 pF typical) placed inline with data traces to suppress ±8 kV contact ESD per IEC 61000-4-2. Use Value: Clamps ESD spikes to ≤13.4 V within <1 ns, preserving signal rise/fall times and preventing bit errors without adding jitter. |
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 | Same VBR range (8.65–9.55 V), but in SMA package (DO-214AC); 400 W rating; higher thermal resistance due to surface-mount footprint | Requires PCB pad redesign; better suited for space-constrained layouts where axial MELF placement is impractical | Select P4SMA9.1A-E3 when board real estate limits use of DO-213AB and thermal management allows higher RθJA |
| SMAJ9.0A | VWM = 7.75 V, VC = 13.6 V at 29.2 A; same DO-214AC package; slightly higher clamping voltage and lower IPPM | Marginally reduced surge margin; acceptable where 0.2 V clamping increase is tolerable for cost-sensitive designs | Choose SMAJ9.0A if supply chain prioritizes second-source availability and minor clamping trade-off is acceptable |
Compared with P4SMA9.1A-E3 and SMAJ9.0A, the TGL41-9.1A-E3/97 offers superior thermal performance via its MELF geometry and lower clamping voltage (13.4 V vs. 13.6 V), making it preferable for high-reliability industrial systems where surge repetition and junction heating are concerns.

FAQ
What is the clamping voltage of the TGL41-9.1A-E3/97 under full-rated surge current?
The TGL41-9.1A-E3/97 has a maximum clamping voltage (VC) of 13.4 V when subjected to its rated peak pulse current of 29.9 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees the protected circuit sees no more than 13.4 V during the surge event. The TGL41-9.1A-E3/97 maintains this clamping performance across its specified operating temperature range.
Is the TGL41-9.1A-E3/97 suitable for bidirectional transient protection?
No, the TGL41-9.1A-E3/97 is unidirectional only, as confirmed in the Vishay datasheet. It is designed to protect DC-biased lines where reverse conduction is not required. For bidirectional applications such as AC lines or differential data buses, a separate bidirectional TVS like the SMBJ9.0CA must be selected. The TGL41-9.1A-E3/97's blue band clearly identifies the cathode and prohibits reverse-voltage operation beyond its specified leakage limit.
What does the "/97" suffix indicate in TGL41-9.1A-E3/97?
Per Vishay's ordering information, the "/97" suffix in TGL41-9.1A-E3/97 specifies the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 5000 units. This contrasts with "/96", which denotes 7-inch tape and reel (1500 units). The "E3" prefix confirms RoHS compliance and commercial-grade qualification. The TGL41-9.1A-E3/97 is fully compatible with standard SMT pick-and-place equipment calibrated for DO-213AB MELF components.
How does the TGL41-9.1A-E3/97 perform under elevated ambient temperatures?
The TGL41-9.1A-E3/97 follows standard derating curves per Figure 2 in its datasheet: peak pulse power decreases linearly above 25 °C ambient, reaching ~50 % of 400 W at 100 °C case temperature. Its maximum junction temperature remains +150 °C, and thermal resistance (RθJA) is optimized by the MELF package's axial heat path. For continuous operation near 100 °C, the TGL41-9.1A-E3/97 requires careful layout with copper pour to maintain safe TJ. The TGL41-9.1A-E3/97 retains full specification compliance only when operated within these derated limits.
Is the TGL41-9.1A-E3/97 recommended for new designs?
No - the Vishay datasheet explicitly states "Not For New Designs" for the entire TGL41 series, citing the P4SMAxxA-E3 family as the designated alternative. While the TGL41-9.1A-E3/97 remains available for legacy support and existing production, new designs should evaluate P4SMA9.1A-E3 or SMAJ9.0A. Aetrix Electronics supports both legacy continuity and migration paths for the TGL41-9.1A-E3/97 and its approved replacements.
