Product details
Overview
ICTE10HE3/51 from Vishay General Semiconductor is a bi-directional TransZORB® transient voltage suppressor (TVS) diode in the 1.5KE case style, rated for 1500 W peak pulse power (10/1000 μs), 10 V stand-off voltage (VWM), 11.7 V minimum breakdown voltage (VBR), and 14.1 V maximum clamping voltage at 10 A (VC). It is AEC-Q101 qualified and designed for automotive-grade surge protection on signal and power lines.
For engineers reviewing the ICTE10HE3/51 datasheet, ICTE10HE3/51 pinout, ICTE10HE3/51 application, or ICTE10HE3/51 equivalent, this device serves as a robust, RoHS-compliant, high-energy TVS for protecting sensitive ICs, MOSFETs, and sensor interfaces against inductive switching transients and lightning-induced surges in automotive and industrial systems.
Technical Context
This bi-directional TVS operates symmetrically in both polarities with no polarity marking, enabling bidirectional clamping without circuit redesign. Its glass-passivated junction ensures stable VBR and low leakage (≤2.0 μA at VWM), while its low incremental surge resistance supports fast response to sub-microsecond transients.
The device complies with JEDEC registered standards and delivers consistent clamping performance: clamping factor of 1.20 at 50% rated power and 1.33 at full 1500 W, verified under 10/1000 μs waveform conditions. Thermal derating follows a defined curve up to TJ = 175 °C, with power dissipation limited to 6.5 W at TL = 75 °C on an infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 12 V automotive systems. |
| VBR (min) | 11.7 V at 1.0 mA - Guaranteed breakdown threshold; ensures reliable triggering above normal operating voltage. |
| VC @ 10 A | 14.1 V - Clamping voltage during 10 A transient; limits downstream voltage stress to ≤14.1 V under standardized surge. |
| PPPM | 1500 W - Peak pulse power handling with 10/1000 μs waveform; enables protection against high-energy ESD and load dump events. |
| TJ max | +175 °C - Maximum junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive reliability per stress test requirements including HTOL, TCT, and HTRB. |
| Package | 1.5KE - Industry-standard axial-leaded package with UL 94 V-0 molded epoxy body and matte tin-plated leads. |
Pinout & Package
ICTE10HE3/51 uses a bi-directional axial-leaded configuration in the 1.5KE case style. As a bi-directional TVS, it has no polarity marking and functions identically in either orientation. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102; the HE3 suffix indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional transient clamp node | No functional distinction between terminals; connects across protected line and ground (or rail-to-rail) without orientation dependency. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage current over temperature and lifetime, critical for automotive field reliability. |
| 1500 W peak pulse power (10/1000 μs) | Withstands high-energy transients such as ISO 7637-2 Pulse 5a (load dump) without degradation. |
| AEC-Q101 qualification | Validates suitability for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |
| Low clamping factor (1.20 at 50% power) | Minimizes voltage overshoot during partial surges, reducing stress on downstream 12 V-rated components. |
| UL 94 V-0 molded epoxy case | Provides flame-retardant mechanical protection and environmental sealing for harsh under-hood mounting. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine control modules from load dump transients per ISO 7637-2. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed between battery rail and ground to limit transient excursions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA | DO-214AA (SMB) package; lower PPPM (600 W); same VWM (10 V) and bi-directional configuration. | Better suited for space-constrained PCBs but not rated for automotive under-hood thermal or surge severity. | Select when board area is limited and surge energy remains below 600 W; verify thermal margin at TL > 75 °C. |
| 1N6383 | Same 1.5KE package and electrical specs (VWM = 10 V, VBR = 11.7 V, VC = 14.1 V), but commercial-grade (E3 suffix), not AEC-Q101 qualified. | Lacks automotive qualification; suitable for industrial or consumer applications where AEC-Q101 is not mandated. | Choose for cost-sensitive non-automotive designs requiring identical clamping performance without qualification overhead. |
Compared with SMBJ10CA and 1N6383, ICTE10HE3/51 uniquely combines AEC-Q101 qualification, 1500 W surge rating, and 1.5KE package robustness-making it the only option among the three validated for under-hood automotive deployment with full ISO 7637-2 compliance margin.

FAQ
What is the polarity configuration of ICTE10HE3/51?
ICTE10HE3/51 is a bi-directional TVS diode with no polarity marking on the package. Both terminals are functionally identical, allowing installation in either orientation across protected lines. This symmetry enables straightforward implementation in AC-coupled or rail-to-rail protection schemes without concern for anode/cathode alignment.
Is ICTE10HE3/51 suitable for automotive under-hood applications?
Yes, ICTE10HE3/51 is AEC-Q101 qualified and rated for TJ = –55 °C to +175 °C, making it suitable for under-hood automotive use. Its 1.5KE package withstands mechanical vibration and thermal cycling, and its 1500 W surge rating meets ISO 7637-2 Pulse 5a requirements for load dump protection in engine control units and body controllers.
What is the clamping voltage of ICTE10HE3/51 at 1 A and 10 A?
Per the Vishay datasheet (Doc. #88356), ICTE10HE3/51 has a maximum clamping voltage (VC) of 13.7 V at IPP = 1.0 A and 14.1 V at IPP = 10 A. These values are measured under standard 10/1000 μs waveform conditions and define the upper voltage limit imposed on protected circuits during transient events.
How does ICTE10HE3/51 differ from ICTE10-E3/51?
ICTE10HE3/51 carries the HE3 suffix, indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. In contrast, ICTE10-E3/51 is RoHS-compliant and commercial-grade (JESD 201 Class 1A), lacking automotive qualification. Both share identical electrical specs and 1.5KE packaging, but only ICTE10HE3/51 is approved for automotive safety-critical applications.
Can ICTE10HE3/51 be used in place of 1N6383?
ICTE10HE3/51 matches 1N6383 electrically (VWM = 10 V, VBR = 11.7 V, VC = 14.1 V) and mechanically (1.5KE package), but adds AEC-Q101 qualification and enhanced whisker resistance. It is a drop-in replacement for 1N6383 in automotive designs; for non-automotive use, 1N6383 may be selected for cost efficiency without sacrificing clamping performance.
