Product details
Overview
P6KE11CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 11 V nominal breakdown voltage (VBR = 10.5–11.6 V at 1.0 mA), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE11CAHE3/54 datasheet, P6KE11CAHE3/54 pinout, P6KE11CAHE3/54 application, or P6KE11CAHE3/54 equivalent, this device serves as a robust, RoHS-compliant, bidirectional surge protection solution for automotive sensor interfaces, industrial I/O lines, and telecom power rails where fast response (<1 ns), low clamping ratio, and high surge immunity are critical.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, with no polarity marking and identical electrical characteristics forward and reverse. Its glass-passivated junction enables stable breakdown behavior and low incremental surge resistance under repetitive 10/1000 μs transients at 0.01% duty cycle.
The device is rated for -55 °C to +175 °C operating junction temperature, features 20 °C/W junction-to-lead thermal resistance, and maintains clamping performance up to 175 °C with derating per Fig. 2. It complies with UL 497B (QVGQ2) and meets JESD 201 Class 2 whisker resistance via HE3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 10.5–11.6 V at 1.0 mA test current - defines precise conduction onset threshold for transient clamping |
| Stand-off Voltage VWM | 9.40 V - maximum continuous working voltage before leakage exceeds 5.0 μA |
| Clamping Voltage VC | 15.6 V at 38.5 A IPPM - limits protected circuit voltage during worst-case 10/1000 μs surge |
| Peak Pulse Power PPPM | 600 W (10/1000 μs waveform) - sustains high-energy surges without failure under defined test conditions |
| Operating Temperature Range | -55 °C to +175 °C - supports under-hood automotive and industrial environments without derating loss |
| Qualification | AEC-Q101 qualified (HE3 suffix) - validated for automotive electronics reliability per stress test requirements |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.242–0.258 inch body length and matte tin leads |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with glass passivated chip junction. Leads are matte tin plated, solderable per J-STD-02 and JESD 22-B102; no polarity marking for bidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path terminal | Either end connects to protected line; no cathode band - identical clamping in both directions |
| Lead 1 / Lead 2 | Current-carrying terminals | Low-inductance path for surge current diversion; thermal interface to PCB copper for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| 600 W peak pulse power (10/1000 μs) | Withstands high-energy lightning-induced or inductive-switching transients common in automotive and industrial systems |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including engine control units, ADAS sensors, and body electronics |
| UL 497B recognition (QVGQ2) | Meets safety standard for telecom and data line protectors - simplifies system-level certification |
| Low clamping ratio (VC/VBR ≈ 1.43) | Minimizes overvoltage stress on downstream ICs like CAN transceivers or microcontrollers during surge events |
Applications
| Automotive Sensor Protection | Industrial I/O Line 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 |
|---|---|---|---|
| SMBJ11CA | Surface-mount SMB package (3.5 mm × 4.5 mm), same VBR range and 600 W rating but lower IPPM (32.9 A) | Better suited for space-constrained PCBs; requires rework for through-hole legacy designs | Select SMBJ11CA only when board layout allows SMD placement and thermal pad design supports 20 °C/W RθJA. |
| P6KE11CA-E3/54 | Same DO-15 package and electrical specs, but commercial-grade (non-AEC-Q101) with JESD 201 Class 1A whisker testing | Limited to non-automotive industrial or consumer use; lacks automotive qualification documentation | Choose P6KE11CA-E3/54 for cost-sensitive non-automotive applications where AEC-Q101 is not mandated. |
Compared with P6KE11CAHE3/54, SMBJ11CA offers smaller footprint but reduced surge current handling and different thermal path, while P6KE11CA-E3/54 provides identical form-factor protection without automotive qualification - making P6KE11CAHE3/54 the sole choice for AEC-Q101-compliant designs requiring through-hole mounting.

FAQ
What is the breakdown voltage tolerance for P6KE11CAHE3/54?
The P6KE11CAHE3/54 has a guaranteed breakdown voltage range of 10.5 V to 11.6 V at 1.0 mA test current, corresponding to ±5% tolerance around the nominal 11 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports precise system-level surge margining in automotive and industrial designs.
Is P6KE11CAHE3/54 suitable for automotive applications?
Yes, P6KE11CAHE3/54 is AEC-Q101 qualified (denoted by HE3 suffix) and rated for -55 °C to +175 °C junction temperature. It is explicitly validated for automotive use cases including engine control, ADAS sensor interfaces, and body electronics where transient immunity and long-term reliability under thermal stress are mandatory.
How does the clamping voltage of P6KE11CAHE3/54 compare to its stand-off voltage?
P6KE11CAHE3/54 has a stand-off voltage (VWM) of 9.40 V and a maximum clamping voltage (VC) of 15.6 V at 38.5 A, yielding a clamping ratio of ~1.66. This ratio reflects effective overvoltage limiting - ensuring protected circuits remain below 15.6 V even during worst-case 600 W surges, while operating safely below 9.40 V during normal conditions.
What is the meaning of the "CA" and "HE3" suffixes in P6KE11CAHE3/54?
The "CA" suffix indicates bidirectional configuration - enabling symmetrical clamping in both polarities without cathode marking. The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, distinguishing it from commercial-grade "E3" variants that lack automotive validation.
Can P6KE11CAHE3/54 replace unidirectional TVS diodes like P6KE11AHE3/54?
No - P6KE11CAHE3/54 is strictly bidirectional and lacks polarity marking, whereas P6KE11AHE3/54 is unidirectional with cathode band. Substitution would compromise protection on DC-biased lines. For bidirectional signal lines (e.g., RS-485, CAN, audio), P6KE11CAHE3/54 is correct; for DC power rails, the unidirectional variant must be used.
