Product details
Overview
P6KE11CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode in DO-15 package, designed for primary-level overvoltage protection on DC power rails and signal lines. It features a 9.4V minimum breakdown voltage, 11.6V maximum reverse standoff voltage, 15.6V clamping voltage at 38A peak pulse current, and fast sub-nanosecond response time - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE11CA-T datasheet, P6KE11CA-T pinout, P6KE11CA-T application, or P6KE11CA-T equivalent, this page delivers verified electrical specs, DO-15 terminal mapping, real-world clamping performance data, and direct alternatives with documented voltage and current trade-offs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling single-device protection of AC-coupled or floating interfaces without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<5.0 µA at VRWM) under steady-state conditions.
The device sustains 600W peak pulse power per 1.0ms 10/1000µs waveform and derates linearly above +25°C ambient, with thermal resistance from junction to ambient rated at 75°C/W. It meets RoHS compliance and supports lead-free reflow soldering per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - withstands 1.0ms transient surges up to 38A without failure |
| Reverse Standoff Voltage (VRWM) | 11.6V max - defines maximum continuous operating voltage before clamping initiates |
| Breakdown Voltage (VBR) | 10.5–11.6V @ 1.0mA - precise threshold where avalanche conduction begins |
| Clamping Voltage (VC) | 15.6V @ 38A IPP - limits downstream circuit voltage during surge events |
| Leakage Current (IR) | ≤5.0 µA @ 11.6V - ensures minimal standby power loss and signal integrity |
| Package | DO-15 - axial-leaded plastic package rated UL 94V-0, 0.4g weight, IATF 16949 manufactured |
Pinout & Package
DO-15 package with two axial leads: no polarity marking for bidirectional operation; leads are plating-solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either lead serves as input/output; identical clamping behavior in both directions |
| Lead 1 / Lead 2 | Current path terminals | Direct connection to protected line and ground/reference; no internal bias or control logic |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 12V systems |
| Glass-passivated die construction | Ensures long-term parameter stability and reduced parameter drift over temperature and life |
| Bidirectional configuration | Eliminates need for dual unidirectional devices in AC or differential signal paths |
| RoHS-compliant lead finish | Supports Pb-free reflow assembly at 260°C peak without degradation of clamping performance |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input rail in programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed directly at connector entry point before EMI filter and DC-DC converter. Use Value: Limits transient voltage to ≤15.6V, preventing damage to upstream TVS arrays and downstream 24V-rated regulators. |
Use Scenario: LIN bus transceiver power supply line in door module subjected to battery reversal and jump-start surges. IC Role / Device Role / Timing Role: Bidirectional rail clamp protecting 5V LDO input from ±30V transients lasting <100ms. Use Value: Symmetric clamping avoids polarity-dependent failure; 38A peak current rating handles 12V system jump-start energy. |
| AC Adapter Output Protection | RS-485 Transceiver Interface |
Use Scenario: Secondary-side 12V output of wall-mount adapter subject to capacitor discharge and hot-plug events. IC Role / Device Role / Timing Role: Final-stage clamp after rectification and bulk capacitance, before USB-PD controller input. Use Value: 15.6V clamping prevents latch-up in 12V-rated USB interface ICs during 10/1000µs surges. |
Use Scenario: Termination node in factory automation RS-485 network experiencing ESD and cable discharge events. IC Role / Device Role / Timing Role: Line-to-ground TVS on A/B differential pair, mounted adjacent to connector. Use Value: Sub-ns response captures fast ESD pulses before transceiver input stages saturate; bidirectional operation protects both polarities of differential swing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA | Same VRWM (11.6V) and VC (17.0V), but 600W rating in smaller SMB package (lower RθJA = 40°C/W) | Better suited for space-constrained PCBs; higher thermal efficiency but lower mechanical robustness than DO-15 | Select when board area is limited and airflow/thermal pad design supports SMB mounting |
| 1.5KE11CA | Higher 1500W peak power, same VRWM/VC, but larger DO-201AD package and 5.0A IFSM vs. 100A | Used where surge energy exceeds 600W (e.g., 48V telecom power inputs); less suitable for high-repetition surges due to lower IFSM | Choose only if validated surge profiles exceed 600W; otherwise, P6KE11CA-T offers better cost and footprint balance |
Compared with SMBJ11CA and 1.5KE11CA, P6KE11CA-T provides optimal mechanical ruggedness and manufacturability in through-hole assembly while maintaining precise 11.6V standoff and 15.6V clamping - making it preferred for industrial controls and legacy automotive designs requiring proven DO-15 reliability.

FAQ
Is P6KE11CA-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE11CA-T and entire P6KE series (DS21502 Rev. 20-4, August 2024). Aetrix Electronics maintains limited legacy stock and supports last-time-buy programs with full traceability and documentation for ongoing production runs.
What is the difference between P6KE11A and P6KE11CA?
P6KE11A is unidirectional with cathode band marking and clamps only in reverse bias; P6KE11CA is bidirectional, marked without cathode band, and clamps symmetrically for both positive and negative transients - critical for AC or floating signal line protection.
Can P6KE11CA-T be used in place of P6KE12CA?
No - P6KE11CA-T has VRWM = 11.6V max and VBR = 10.5–11.6V, while P6KE12CA specifies VRWM = 12.6V max and VBR = 11.4–12.6V. Substituting introduces 1.0V lower standoff margin, risking premature clamping in 12V nominal systems.
Does P6KE11CA-T meet AEC-Q200 requirements?
While manufactured in IATF 16949-certified facilities and qualified for automotive change control, the P6KE11CA-T itself is not AEC-Q200 stress-tested. Diodes recommends P6S1U11CA or SMAJ11CA for AEC-Q200-compliant designs.
