Product details
Overview
P6KE11CHE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for primary overvoltage protection of sensitive electronics. It features 600 W peak pulse power (10/1000 μs), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 10.5 V breakdown voltage at 1 mA test current - deployed on DC power rails and I/O lines in automotive ECUs and industrial controllers.
For engineers reviewing the P6KE11CHE3/73 datasheet, P6KE11CHE3/73 pinout, P6KE11CHE3/73 application, or P6KE11CHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.075 %/°C breakdown voltage temperature coefficient, and RoHS-compliant matte tin-plated leads suitable for J-STD-002 solderability requirements.
Technical Context
This device operates as a voltage-clamping surge protector: under normal conditions it presents high impedance (>1 MΩ at 9.4 V), but triggers into low-impedance conduction when transient voltage exceeds its 10.5 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns) to ESD and lightning-induced transients.
The P6KE11CHE3/73 is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), with thermal resistance of 20 °C/W junction-to-lead - enabling effective heat dissipation in PCB-mounted applications without heatsinking. Its 5.0 W steady-state power dissipation supports continuous operation in ambient temperatures up to 75 °C at lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 10.5 V min / 11.6 V max at 1 mA - defines precise turn-on threshold for reliable clamping initiation |
| Stand-off Voltage VWM | 9.40 V - maximum continuous reverse working voltage before leakage exceeds 5 μA |
| Clamping Voltage VC | 15.6 V at 38.5 A IPPM - limits protected circuit voltage during worst-case 600 W transient |
| Peak Pulse Power | 600 W (10/1000 μs waveform) - sustains high-energy surges common in automotive load-dump events |
| Junction Temperature Range | -55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with UL 94 V-0 molded epoxy housing |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, cylindrical epoxy body with cathode band marking. Leads are matte tin-plated, solderable per J-STD-002, with 0.300" (7.6 mm) minimum lead length and 0.140" (3.6 mm) maximum body diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side (e.g., GND) in uni-directional TVS configuration |
| Cathode (banded end) | Current exit point during reverse-biased clamping | Connected to protected line (e.g., 12 V rail); clamps transients to safe level when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable leakage current (<5 μA at VWM) and long-term reliability under thermal cycling |
| 600 W peak pulse power (10/1000 μs) | Withstands automotive load-dump transients (ISO 7637-2 Pulse 5a) without degradation |
| AEC-Q101 qualification | Validated for automotive electronics use including engine control units and ADAS sensor interfaces |
| Low clamping ratio (VC/VBR = 1.49) | Minimizes voltage overshoot during surge events, protecting downstream MOSFETs and ICs |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and UL 94 V-0 flammability for safety-critical designs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower peak pulse power (400 W), SMA package (surface-mount), 10.0 V VBR min | Better suited for space-constrained PCB layouts; less robust for high-energy automotive transients | Select when board area is limited and surge energy does not exceed 400 W |
| 1.5KE11A | Same DO-15 package, higher 1500 W rating, 11.1 V VBR min, larger body size (DO-201AD) | Designed for higher-energy industrial surge standards (IEC 61000-4-5 Level 4) | Choose when legacy DO-15 footprint compatibility is required with enhanced 1500 W capability |
Compared with SMAJ10A and 1.5KE11A, the P6KE11CHE3/73 delivers optimal balance of AEC-Q101 qualification, 600 W surge handling, and cost-effective DO-15 through-hole assembly - making it preferred for automotive and industrial applications where reliability and proven qualification outweigh ultra-compact packaging or extreme power ratings.

FAQ
What is the breakdown voltage specification for P6KE11CHE3/73?
The P6KE11CHE3/73 has a minimum breakdown voltage (VBR) of 10.5 V and a maximum of 11.6 V at 1 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in 12 V systems where the P6KE11CHE3/73 is commonly applied.
Is P6KE11CHE3/73 qualified for automotive use?
Yes, the P6KE11CHE3/73 carries the HE3 suffix indicating AEC-Q101 qualification - verified for automotive-grade reliability including temperature cycling, highly accelerated life testing (HALT), and ESD immunity. This makes the P6KE11CHE3/73 suitable for under-hood and chassis-mounted applications where the P6KE11CHE3/73 must endure harsh thermal and mechanical stress.
What does the "HE3" suffix mean in P6KE11CHE3/73?
The "HE3" suffix denotes RoHS-compliant construction with JESD 201 Class 2 whisker resistance and full AEC-Q101 qualification. Unlike the commercial-grade "E3" variant, the HE3 version undergoes additional automotive-specific stress testing and is approved for use in safety-critical vehicle subsystems - a key differentiator for the P6KE11CHE3/73 in automotive BOMs.
How does P6KE11CHE3/73 compare to bi-directional TVS diodes like P6KE11CA?
The P6KE11CHE3/73 is uni-directional and features a cathode band for polarity-sensitive placement, whereas P6KE11CA is bi-directional with no polarity marking. The P6KE11CHE3/73 offers lower forward voltage drop (3.5 V at 50 A) and is optimized for DC rail protection; P6KE11CA suits AC-coupled or bidirectional signal lines where polarity reversal occurs.
What is the maximum clamping voltage of P6KE11CHE3/73 during a surge event?
The P6KE11CHE3/73 clamps to a maximum of 15.6 V when subjected to its rated 38.5 A peak pulse current (10/1000 μs waveform). This clamping voltage - combined with its 10.5 V breakdown threshold - yields a clamping ratio of 1.49, ensuring protected circuits remain within safe operating limits during transient events where the P6KE11CHE3/73 activates.
