Product details
Overview
TGL41-12-E3/96 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 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), 24.0 A peak pulse current (IPPM), 16.7 V maximum clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs). Used in sensor signal line protection for industrial control systems.
For engineers reviewing the TGL41-12-E3/96 datasheet, TGL41-12-E3/96 pinout, TGL41-12-E3/96 application, or TGL41-12-E3/96 equivalent, key selection criteria include unidirectional polarity, 10.2 V working voltage compatibility, 16.7 V clamping performance under 24 A surge, DO-213AB mechanical footprint, and RoHS-compliant matte tin terminations.
Technical Context
This TVS diode operates exclusively in unidirectional mode with cathode marked by a blue band. Its glass-passivated junction enables fast response time and low incremental surge resistance, critical for suppressing inductive switching spikes and lightning-induced surges on low-voltage signal paths.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 250 °C). Its 1.0 W steady-state power dissipation and 40 A 8.3 ms forward surge rating support robust transient handling without thermal runaway in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V - ensures reliable conduction onset above normal 10.2 V operating voltage while avoiding false triggering |
| VWM | 10.2 V - maximum continuous reverse voltage before leakage exceeds 5 μA, compatible with 12 V nominal systems |
| VC @ IPPM | 16.7 V - clamped voltage during 24.0 A transient, limiting downstream IC stress to safe levels |
| IPPM | 24.0 A - peak surge current capability with 10/1000 µs waveform, sufficient for IEC 61000-4-5 Level 3 |
| PPPM | 400 W - transient power absorption capacity, derated linearly above 25 °C ambient per Fig. 2 |
| TJ max. | 150 °C - maximum junction temperature, enabling operation in enclosed industrial enclosures |
| Package | DO-213AB (GL41) - cylindrical MELF outline with 2.41–2.67 mm diameter, optimized for automated placement |
Pinout & Package
DO-213AB (GL41) is a two-terminal axial plastic MELF package with matte tin-plated solderable ends. The blue band denotes the cathode (positive terminal under reverse-bias clamping condition); the anode is the unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (blue band) | Transient clamp output node | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane; completes clamping current path |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity only | Enables precise clamping on DC-biased lines without forward conduction during normal operation |
| Glass passivated chip junction | Ensures stable VBR tolerance (±5 %) and low leakage (<5 μA at VWM) over temperature and life |
| 400 W peak pulse power (10/1000 µs) | Supports repeated surge events per IEC 61000-4-5 with 0.01 % duty cycle without degradation |
| MSL Level 1 compliance | Allows direct placement onto PCBs without baking, reducing manufacturing overhead |
| RoHS-compliant E3 suffix | Meets JESD 201 Class 1A whisker resistance and UL 94 V-0 flammability for safety-critical designs |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module Inputs |
|---|---|
Use Scenario: Protecting 12 V analog sensor outputs (e.g., pressure, temperature) from load dump and inductive kickback in factory automation PLCs. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between sensor output and microcontroller ADC input. Use Value: Limits transient voltage to ≤16.7 V during 24 A surges, preventing ADC saturation and latch-up in downstream MCU. | Use Scenario: Safeguarding LIN bus slave node inputs against battery transients and alternator ripple in door module ECUs. IC Role / Device Role / Timing Role: Standoff protector on LIN data line referenced to chassis ground, with 10.2 V VWM matching LIN's 12 V supply margin. Use Value: Maintains signal integrity below 16.7 V clamping threshold while drawing <5 μA leakage at 12 V, minimizing bus loading. |
| Telecom Power Supply Input Stage | Consumer Appliance Motor Driver Feedback Lines |

IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical) unidirectional clamp on differential encoder lines referenced to 5 V supply. Use Value: Clamps common-mode spikes to ≤16.7 V without distorting 50 kHz PWM timing edges due to minimal junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | DO-214AA (SMB) package; 12.2–13.5 V VBR; 19.9 V VC @ 21.1 A; higher mounting height | Requires PCB pad redesign; better suited for high-volume SMT assembly with pick-and-place vacuum nozzles | Select SMBJ12A when board space allows larger footprint and higher IPPM margin is needed beyond 24 A |
| P6KE13A | DO-15 axial leaded package; 12.4–13.7 V VBR; 21.2 V VC @ 18.9 A; through-hole mounting | Not suitable for automated surface-mount production; requires wave soldering or hand assembly | Choose P6KE13A only for prototyping or legacy through-hole designs where MELF placement equipment is unavailable |
Compared with SMBJ12A and P6KE13A, the TGL41-12-E3/96 delivers identical clamping performance in a smaller DO-213AB footprint with superior thermal cycling reliability and RoHS-compliant matte tin terminations-ideal for high-density industrial PCBs requiring automated placement.

FAQ
What is the breakdown voltage range of the TGL41-12-E3/96?
The TGL41-12-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 tight ±5 % tolerance ensures predictable clamping onset in 12 V systems and is validated across the full -55 °C to 150 °C operating junction temperature range. The TGL41-12-E3/96 maintains this specification without drift under repetitive surge conditions.
Does the TGL41-12-E3/96 support bidirectional transient suppression?
No, the TGL41-12-E3/96 is unidirectional only, as confirmed in the Vishay datasheet revision 11-Dec-12. It conducts surge current only when the cathode (blue band) is positive relative to the anode. For bidirectional protection, a separate device such as the TGL41-12CA would be required. The TGL41-12-E3/96's unidirectional design minimizes leakage and optimizes clamping accuracy on DC-biased lines.
What is the maximum clamping voltage of the TGL41-12-E3/96 under surge conditions?
The TGL41-12-E3/96 exhibits a maximum clamping voltage (VC) of 16.7 V at its rated peak pulse current (IPPM) of 24.0 A using a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during worst-case transients. The TGL41-12-E3/96 achieves this with low incremental surge resistance, ensuring consistent performance across production lots.
Is the TGL41-12-E3/96 RoHS compliant and lead-free?
Yes, the TGL41-12-E3/96 carries the E3 suffix, indicating full RoHS compliance per Directive 2011/65/EU and JESD 201 Class 1A whisker resistance. Its matte tin-plated terminals meet J-STD-002 solderability requirements and UL 94 V-0 flammability standards. The TGL41-12-E3/96 is manufactured without lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances above threshold limits.
What is the thermal rating and derating behavior of the TGL41-12-E3/96?
The TGL41-12-E3/96 has a maximum junction temperature (TJ) of 150 °C and a steady-state power dissipation (PD) of 1.0 W on an infinite heatsink at 75 °C lead temperature. Its pulse power rating derates linearly above 25 °C ambient, per Figure 2 in the Vishay datasheet. The TGL41-12-E3/96 maintains full 400 W peak pulse capability only at TA ≤ 25 °C; at 75 °C, it supports ~280 W.
