Product details
Overview
ICTE15HE3/51 from Vishay General Semiconductor is a bi-directional TransZORB® transient voltage suppressor (TVS) diode in the 1.5KE package, rated for 15 V stand-off voltage (VWM), 17.6 V minimum breakdown voltage (VBR), and 1500 W peak pulse power (10/1000 μs). It provides bidirectional clamping for surge protection on signal or power lines in automotive and industrial electronics.
For engineers reviewing the ICTE15HE3/51 datasheet, ICTE15HE3/51 pinout, ICTE15HE3/51 application, or ICTE15HE3/51 equivalent, key selection criteria include its AEC-Q101 qualification, 20.8 V clamping voltage at 10 A, 2.0 μA max reverse leakage at 15 V, 175 °C max junction temperature, and compatibility with high-reliability PCB assembly per J-STD-002 and JESD 201 Class 2 whisker test.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction enables fast response time (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching transients.
The device is designed for unidirectional or bi-directional configurations - ICTE15HE3/51 uses the "C" suffix to denote bi-directional functionality and lacks polarity marking. It meets JEDEC registered standards and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min) | 17.6 V at 1.0 mA - guaranteed breakdown threshold ensuring predictable turn-on |
| VC @ 10 A | 20.8 V - clamping voltage during 10 A transient, defining worst-case overvoltage seen by protected circuit |
| PPPM | 1500 W - peak pulse power handling with 10/1000 μs waveform, enabling robust surge immunity |
| ID @ VWM | ≤2.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on systems |
| TJ max | +175 °C - extended thermal range supports under-hood and industrial ambient conditions |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), validating robustness against repetitive load dumps |
Pinout & Package
ICTE15HE3/51 is housed in the industry-standard Case Style 1.5KE molded epoxy package (DO-201AD), with two axial leads and no polarity marking due to bi-directional symmetry.

| UL 94 V-0 molding compound | Ensures flame retardancy in enclosed enclosures and high-density PCB assemblies |
| Low clamping factor (1.33 at full power) | Minimizes overvoltage overshoot during worst-case transients, protecting downstream ICs |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple transients.

IC Role / Device Role / Timing Role: Across-motor terminals or H-bridge supply rails to clamp flyback spikes during PWM commutation. Use Value: 1500 W rating handles repeated 100 A transients; 175 °C TJ max ensures stability near heat-generating motor drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | 600 W PPPM, DO-214AA package, lower power density and smaller footprint | Better suited for space-constrained consumer PCBs; insufficient for automotive load dump | Select when board area is critical and surge energy is ≤600 W |
| 1N6385 | Same electrical specs and 1.5KE package; differs only in packaging code (bulk vs. tape/reel) and whisker test class (Class 1A vs. Class 2) | Identical functional performance; differs only in manufacturing traceability and plating validation | Choose for cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with SMBJ15CA and 1N6385, ICTE15HE3/51 delivers higher surge robustness (1500 W vs. 600 W) and automotive-grade reliability (AEC-Q101 + JESD 201 Class 2), making it optimal for mission-critical power rail protection where sustained energy absorption and long-term plating integrity are mandatory.

FAQ
What is the clamping voltage of ICTE15HE3/51 at 10 A?
The clamping voltage of ICTE15HE3/51 is 20.8 V at 10 A (10/1000 μs waveform), measured per JEDEC standards. This value defines the maximum voltage imposed on the protected circuit during a 10 A transient event and is critical for ensuring downstream components remain within safe operating limits. The ICTE15HE3/51 achieves this while maintaining low leakage and AEC-Q101 qualification.
Is ICTE15HE3/51 unidirectional or bidirectional?
ICTE15HE3/51 is a bi-directional TVS diode, indicated by the "C" suffix in its part number. It provides symmetrical clamping in both polarities with identical VBR (17.6 V min), VC (20.8 V @ 10 A), and leakage characteristics. Unlike unidirectional variants, ICTE15HE3/51 has no cathode marking and may be mounted without orientation constraints.
Does ICTE15HE3/51 meet AEC-Q101 requirements?
Yes, ICTE15HE3/51 is explicitly qualified to AEC-Q101 for automotive applications. The "HE3" suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker testing, and the device is listed in Vishay's AEC-Q101 qualified product portfolio. This certification validates its reliability under temperature cycling, mechanical shock, and high-humidity operating conditions typical of automotive under-hood use.
What package type does ICTE15HE3/51 use?
ICTE15HE3/51 uses the Case Style 1.5KE package (DO-201AD), a standard axial-leaded, molded epoxy housing with UL 94 V-0 flammability rating. Its dimensions (0.375" lead length, 0.210" body diameter) support wave and reflow soldering, and the matte tin-plated leads comply with J-STD-002 for solderability and JESD 201 Class 2 for whisker resistance.
How does ICTE15HE3/51 compare to ICTE15E3/51?
ICTE15HE3/51 and ICTE15E3/51 share identical electrical specifications (VWM = 15 V, VBR = 17.6 V, VC = 20.8 V @ 10 A) and 1.5KE packaging, but differ in qualification level: ICTE15HE3/51 is AEC-Q101 qualified with JESD 201 Class 2 whisker testing, whereas ICTE15E3/51 is commercial-grade (JESD 201 Class 1A). Both are bi-directional and RoHS-compliant, but ICTE15HE3/51 is specified for automotive and high-reliability industrial use.
