Product details
Overview
TGL41-12A-E3/96 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in GL41 (DO-213AB) MELF package, with 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), and 400 W peak pulse power (10/1000 μs). It clamps transients to ≤16.7 V at 24.0 A peak pulse current and operates from −55 °C to +150 °C, used for protecting MOSFETs and ICs against inductive switching surges in industrial power supplies.
For engineers reviewing the TGL41-12A-E3/96 datasheet, TGL41-12A-E3/96 pinout, TGL41-12A-E3/96 application, or TGL41-12A-E3/96 equivalent, key selection criteria include unidirectional polarity, 10.2 V working voltage, 16.7 V clamping voltage at 24 A, DO-213AB mechanical compatibility, and RoHS-compliant matte tin terminals meeting J-STD-002 solderability.
Technical Context
This TVS diode uses a glass-passivated planar junction in a plastic MELF case, enabling fast response time and low incremental surge resistance. Its unidirectional configuration provides forward conduction only during overvoltage events, with cathode marked by a blue band and polarity defined relative to anode.
The device meets MSL Level 1 per J-STD-020, supports automated placement, and delivers 400 W peak pulse power at 25 °C - derated linearly above 25 °C per Fig. 2, dropping to 200 W above 91 V. It exhibits 0.081 %/°C temperature coefficient of VBR, ensuring stable clamping across operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V - ensures reliable triggering above 10.2 V system operating voltage while avoiding false trips |
| VWM | 10.2 V - maximum continuous reverse voltage the device blocks without significant leakage |
| VC @ IPPM | 16.7 V - clamped voltage seen by protected circuit when subjected to 24.0 A transient current |
| IPPM | 24.0 A - peak surge current capability under standardized 10/1000 μs waveform |
| PPPM | 400 W - transient energy absorption capacity at 25 °C, critical for inductive load switching protection |
| TJ max. | +150 °C - maximum junction temperature allowing operation in high-ambient industrial environments |
| Leakage @ VWM | 5.0 μA - minimal reverse current that avoids loading sensitive signal lines or reference nodes |
Pinout & Package
GL41 (DO-213AB) is a cylindrical plastic MELF package with solderable matte tin-plated ends. The blue band denotes the cathode terminal, which is positive with respect to the anode during TVS conduction. No internal leads or pads - terminals are the two axial ends of the cylindrical body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band end) | Transient current sink | Connected to protected line; conducts surge current to ground path during overvoltage |
| Anode (unmarked end) | Reference/ground return | Typically tied to system ground or low-impedance return path to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against high-energy transients from relay coils or motor drivers without thermal runaway |
| Glass-passivated planar junction | Provides stable VBR tolerance and long-term reliability under repeated surge stress |
| MSL Level 1 rating | Allows direct placement on PCB without baking, supporting standard SMT reflow profiles up to 250 °C peak |
| Unidirectional polarity only | Simplifies design for DC-biased lines where reverse conduction is not required, reducing capacitance vs. bidirectional variants |
| DO-213AB mechanical outline | Ensures compatibility with existing MELF pick-and-place tooling and board layouts optimized for GL41 footprint |
Applications
| Industrial Motor Drives | DC Power Supply Inputs |
|---|---|
Use Scenario: Protection of gate drivers and logic inputs against flyback voltage spikes from solenoid or relay coil de-energization. IC Role / Device Role / Timing Role: TVS diode placed across coil or in series with driver output to clamp inductive kick to safe levels. Use Value: Prevents latch-up or permanent damage to 12 V-rated control ICs by limiting transient voltage to ≤16.7 V at 24 A. | Use Scenario: Input-stage surge suppression on 12 V DC-DC converter front-ends exposed to automotive or factory floor transients. IC Role / Device Role / Timing Role: Primary transient shunt located between input rail and chassis ground before EMI filter. Use Value: Absorbs 400 W pulses without degradation, maintaining 10.2 V nominal operation while blocking <5 μA leakage. |
| MOSFET-Based Switching Circuits | Sensor Signal Line Protection |
Use Scenario: Clamping of drain-source voltage overshoot during turn-off of N-channel MOSFETs driving inductive loads. IC Role / Device Role / Timing Role: Connected from MOSFET drain to source (or ground), conducting only during overvoltage events. Use Value: Limits VDS to 16.7 V, preventing avalanche failure and extending MOSFET lifetime in 12 V systems. | Use Scenario: Protection of analog sensor outputs (e.g., pressure or temperature transducers) connected to microcontrollers via long cables. IC Role / Device Role / Timing Role: Placed at connector interface to divert ESD and lightning-induced surges away from ADC input pins. Use Value: Low 5 μA leakage avoids signal offset; 16.7 V clamping preserves 12-bit ADC accuracy in 3.3 V or 5 V domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P4SMA12A-E3/96 | Same VWM (10.2 V), identical VC (16.7 V), but in SMA package (DO-214AC); 600 W PPPM rating | Higher power handling but larger footprint; requires PCB layout change from MELF to flat SMD | Select for higher surge margin where space permits and MELF placement is unavailable |
| SMAJ12A | Same DO-214AC package; VBR 13.3–14.7 V, VC 19.9 V - looser tolerance and higher clamping | Less precise clamping; suitable only where 19.9 V is acceptable for protected ICs | Choose only if tighter VBR and lower VC are not required for system-level immunity |
Compared with P4SMA12A-E3/96 and SMAJ12A, the TGL41-12A-E3/96 offers superior VBR tightness (±5.3 %), lower clamping voltage, and MELF form factor ideal for high-density or automated optical inspection-sensitive layouts - making it preferred for space-constrained industrial controls where precision clamping is critical.

FAQ
What is the breakdown voltage range for TGL41-12A-E3/96?
The TGL41-12A-E3/96 has a guaranteed breakdown voltage (VBR) range of 11.4 V to 12.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This ±5.3 % tolerance ensures predictable triggering behavior in 12 V systems while avoiding premature conduction during normal operation. The value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88403.
Is TGL41-12A-E3/96 suitable for bidirectional transient protection?
No, TGL41-12A-E3/96 is unidirectional only, as explicitly stated in the Features section and confirmed by its single blue band cathode marking and absence of bidirectional specifications. For AC or dual-polarity signal lines, a separate bidirectional TVS such as SMBJ12CA must be selected - the TGL41-12A-E3/96 will not conduct in reverse bias beyond its specified leakage.
What is the maximum clamping voltage of TGL41-12A-E3/96 under surge conditions?
The TGL41-12A-E3/96 clamps to a maximum of 16.7 V when subjected to its rated 24.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the worst-case voltage imposed on the protected circuit during a full-power transient event.
Does TGL41-12A-E3/96 meet RoHS requirements?
Yes, the "E3" suffix in TGL41-12A-E3/96 indicates RoHS compliance per EU Directive 2011/65/EU and Vishay's material categorization standard. The matte tin-plated terminals comply with JESD 201 Class 1A whisker testing, and the molding compound meets UL 94 V-0 flammability rating - all verified in the Mechanical Data section of document 88403.
What is the thermal derating behavior of TGL41-12A-E3/96 above 25 °C?
TGL41-12A-E3/96 follows linear derating of peak pulse power above 25 °C, as shown in Figure 2 of document 88403: power capability decreases proportionally with rising junction temperature, reaching 200 W at 91 V and above. At 125 °C ambient, the usable PPPM is approximately 280 W - engineers must apply this curve when designing for high-temperature enclosures or adjacent to heat sources.
