Product details
Overview
1N6375HE3/51 from Vishay General Semiconductor is a bi-directional TransZORB® transient voltage suppressor (TVS) diode in the 1.5KE package, rated for 1500 W peak pulse power (10/1000 μs), 10.0 V stand-off voltage (VWM), and 11.7 V minimum breakdown voltage (VBR). It clamps to ≤14.1 V at 10 A surge current and operates from –55 °C to +175 °C, serving as primary overvoltage protection on signal lines and power rails in automotive sensor interfaces.
For engineers reviewing the 1N6375HE3/51 datasheet, 1N6375HE3/51 pinout, 1N6375HE3/51 application, or 1N6375HE3/51 equivalent, key selection criteria include its AEC-Q101 qualification, bi-directional clamping symmetry, 2.0 μA max reverse leakage at VWM, low incremental surge resistance, and compatibility with high-reliability industrial and automotive ESD/surge protection layouts.
Technical Context
The 1N6375HE3/51 implements a glass-passivated silicon junction optimized for fast response (<1 ns) to transient events such as inductive switching spikes and lightning-induced surges. Its bi-directional architecture enables symmetric clamping in both polarities without external polarity management.
It delivers 1500 W peak pulse power under JEDEC-standard 10/1000 μs waveform conditions at 0.01 % duty cycle, with clamping voltage tightly controlled at 14.1 V (max) at 10 A and 13.7 V (max) at 1 A - enabling predictable voltage limiting for downstream ICs like microcontrollers and CAN transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.0 V - maximum continuous reverse operating voltage before conduction begins; defines safe working margin below breakdown. |
| VBR (min) | 11.7 V at 1.0 mA - guaranteed minimum breakdown threshold; ensures reliable triggering above system nominal voltage. |
| VC @ 10 A | ≤14.1 V - clamping voltage during 10 A transient; determines maximum stress imposed on protected circuitry. |
| PPPM | 1500 W - peak pulse power handling per 10/1000 μs waveform; supports robust surge immunity per IEC 61000-4-5 Level 4. |
| IR @ VWM | ≤2.0 μA - ultra-low reverse leakage; minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ range | –55 °C to +175 °C - extended junction temperature capability; enables deployment in under-hood automotive and industrial environments. |
Pinout & Package
Package: Case Style 1.5KE - molded epoxy body with matte tin-plated leads, UL 94 V-0 rated, lead length ≥1.0 inch (25.4 mm), diameter 0.210 inch (5.3 mm). Bi-directional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path terminal | Identical electrical behavior in either direction; connects across protected line and ground or between differential lines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control, ADAS, and body electronics. |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives, critical for field-deployed industrial systems. |
| 1500 W peak pulse rating | Meets IEC 61000-4-5 (10/1000 μs) Level 4 (4 kV) surge immunity without derating in standard PCB layouts. |
| Low clamping factor (1.20 @ 50 % PPPM) | Minimizes voltage overshoot during partial-power transients, improving protection margin for 3.3 V and 5 V logic interfaces. |
| JESD 201 Class 2 whisker resistance | HE3 suffix confirms compliance with stringent tin whisker mitigation - essential for high-reliability aerospace and medical applications. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |

IC Role / Device Role / Timing Role: Across-line TVS connected between AC mains inputs (L–N) to clamp fast-rising transients generated by motor arcing. Use Value: 1500 W rating and 200 A IFSM withstand repeated 100 A surge events typical of brushed motor turn-off, extending MCU lifespan. |
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 | Lower peak power (600 W), smaller SMB package (3.5 × 4.6 mm), higher VC (17.0 V @ 10 A). | Better suited for space-constrained consumer PCBs where 1500 W is not required; less robust for industrial surge standards. | Select when board area is critical and surge threat level is limited to IEC 61000-4-4 (EFT), not full IEC 61000-4-5. |
| 1N6375HE3/36 | Same electrical specs and AEC-Q101 qualification, but supplied in 36" lead length (vs. 51" for 1N6375HE3/51) and different tape/reel packaging (code 36 vs. 51). | No functional difference; only mechanical handling and assembly process variation. | Choose based on SMT placement equipment feed requirements - 1N6375HE3/51 matches 13" reel and 51" lead length for standard pick-and-place tooling. |
Compared with SMBJ10CA and 1N6375HE3/36, the 1N6375HE3/51 uniquely combines 1500 W surge capacity, AEC-Q101 qualification, and 51" lead length optimized for automated insertion - making it the preferred choice for high-reliability automotive and industrial surge protection where layout space permits the 1.5KE form factor.

FAQ
What is the clamping voltage of the 1N6375HE3/51 at 10 A?
The 1N6375HE3/51 has a maximum clamping voltage (VC) of 14.1 V at 10 A peak pulse current under the standard 10/1000 μs waveform. This value is guaranteed per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 12 V nominal systems and 5 V logic interfaces downstream of the 1N6375HE3/51.
Is the 1N6375HE3/51 suitable for automotive applications?
Yes, the 1N6375HE3/51 is AEC-Q101 qualified and explicitly rated for automotive use. Its 175 °C maximum junction temperature, glass-passivated junction, and 1500 W surge capability meet requirements for engine control units, body electronics, and ADAS sensor modules. The HE3 suffix confirms JESD 201 Class 2 whisker resistance - a mandatory requirement for automotive-grade solder joint reliability in the 1N6375HE3/51.
What does the "HE3/51" suffix mean in 1N6375HE3/51?
In 1N6375HE3/51, "HE3" denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification, while "/51" specifies the lead length (51 inches) and packaging format - 13" diameter paper tape and reel with 1400 units per reel. This distinguishes it from variants like 1N6375HE3/36 (36" leads) and ensures compatibility with specific automated assembly equipment used for the 1N6375HE3/51.
How does the 1N6375HE3/51 differ from uni-directional versions like 1N6375?
The 1N6375HE3/51 is a bi-directional TVS diode, meaning it provides symmetrical clamping in both polarities with no cathode marking, whereas the base 1N6375 is uni-directional and features a color band indicating cathode. Electrically, the 1N6375HE3/51 has identical VWM (10.0 V), VBR (11.7 V min), and VC ratings but is intended for AC-coupled or floating signal lines where polarity reversal may occur - a key functional distinction built into the 1N6375HE3/51 design.
What is the maximum operating temperature for the 1N6375HE3/51?
The 1N6375HE3/51 has a specified operating junction and storage temperature range of –55 °C to +175 °C. This wide thermal envelope allows deployment in under-hood automotive locations, industrial motor drives, and outdoor telecom enclosures. Derating curves in the datasheet confirm usable power dissipation down to zero watts at 175 °C ambient - a defining thermal specification of the 1N6375HE3/51.
