Product details
Overview
P6KE11CA-E3/54 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), 15.6 V maximum clamping voltage at 38.5 A peak pulse current, and 9.40 V stand-off voltage - deployed to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P6KE11CA-E3/54 datasheet, P6KE11CA-E3/54 pinout, P6KE11CA-E3/54 application, or P6KE11CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical breakdown behavior in both polarities, enabling use on AC-coupled or floating lines without polarity concerns. Its glass-passivated junction ensures stable leakage (<5.0 μA at 9.40 V) and fast response time (<1.0 ns), critical for suppressing ESD and inductive switching spikes before downstream components are damaged.
The P6KE11CA-E3/54 delivers 600 W transient power handling per IEC 61000-4-5 waveform, with thermal resistance of 20 °C/W (junction-to-lead) and 75 °C/W (junction-to-ambient), supporting reliable operation up to 175 °C junction temperature under pulsed conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 9.40 V - maximum continuous reverse voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 10.5–11.6 V at 1.0 mA - defines onset of avalanche conduction in either direction |
| Clamping Voltage (VC) | 15.6 V at 38.5 A IPPM - maximum voltage seen by protected circuit during 10/1000 μs surge |
| Peak Pulse Power (PPPM) | 600 W - surge energy absorption capacity per single 10/1000 μs event |
| Junction Temperature Range | −55 °C to +175 °C - enables deployment in under-hood automotive and industrial environments |
| Package | DO-15 (DO-204AC) - industry-standard axial leaded package with 0.242–0.258 inch body length |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads; no polarity marking for bidirectional types - terminals are non-polarized and electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Either terminal serves as input/output; identical clamping behavior in both directions |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Ensures stable leakage current (<5.0 μA) and long-term reliability under thermal cycling |
| 600 W peak pulse rating (10/1000 μs) | Supports robust protection against IEC 61000-4-4/5 level 4 surges without derating |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., load dump, ESD) |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Input Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | DO-214AA package, lower RθJA (50 °C/W), same VWM/VBR/VC ratings | Surface-mount layout; better thermal performance but requires rework for through-hole designs | Select when board space is constrained and SMT assembly is available |
| 1.5KE11CA | Higher PPPM (1500 W), larger DO-201AD package, identical electrical specs | Higher surge margin for infrequent but extreme events (e.g., utility grid faults) | Choose where legacy 1.5 kW surge standards apply and board real estate permits larger footprint |
Compared with SMBJ11CA and 1.5KE11CA, the P6KE11CA-E3/54 offers optimal balance of cost, DO-15 through-hole compatibility, and AEC-Q101 qualification - making it preferred for high-volume automotive and industrial through-hole assemblies requiring validated reliability.

FAQ
What does the "CA" suffix indicate in P6KE11CA-E3/54?
The "CA" suffix denotes that the P6KE11CA-E3/54 is a bidirectional Transient Voltage Suppressor, meaning it provides symmetrical clamping in both forward and reverse directions. This allows it to protect AC-coupled or floating signal lines without polarity constraints - unlike unidirectional variants (e.g., P6KE11A) which require correct cathode orientation.
Is P6KE11CA-E3/54 qualified for automotive use?
Yes, the P6KE11CA-E3/54 is AEC-Q101 qualified when ordered with the HE3 suffix (e.g., P6KE11CAHE3/54). The E3/54 variant is RoHS-compliant commercial grade; however, its construction, glass passivation, and 175 °C junction rating align with automotive stress requirements - and many customers deploy it in non-safety-critical automotive modules with internal qualification.
What is the maximum clamping voltage of P6KE11CA-E3/54 under surge conditions?
The P6KE11CA-E3/54 has a maximum clamping voltage (VC) of 15.6 V at 38.5 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is guaranteed across temperature and represents the highest voltage imposed on protected circuitry during worst-case transient events.
Can P6KE11CA-E3/54 replace P6KE11A in an existing design?
No - P6KE11CA-E3/54 is bidirectional while P6KE11A is unidirectional. Substituting them requires verifying line polarity, checking for reverse-bias leakage paths, and confirming that the protected circuit tolerates symmetrical clamping. The P6KE11CA-E3/54 lacks a cathode band marking, so physical orientation becomes irrelevant - but system-level functionality must be revalidated.
What is the thermal resistance of P6KE11CA-E3/54, and how does it affect layout?
The P6KE11CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. For sustained surge duty, minimize trace length to ground planes and use wide copper pours on both leads - especially important in automotive applications where ambient temperatures exceed 85 °C and thermal derating curves (Fig. 2) must be applied.
