Product details
Overview
P6KE13A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 11.1V minimum breakdown voltage, 13.7V maximum standoff voltage, 18.2V clamping voltage at 33A peak pulse current, and DO-15 package with glass-passivated junction - used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE13A-T datasheet, P6KE13A-T pinout, P6KE13A-T application, or P6KE13A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VMAX, peak pulse current handling under IEC 61000-4-5 surge waveforms, thermal derating at elevated ambient temperatures, and unidirectional polarity alignment with DC-biased circuits.
Technical Context
The P6KE13A-T operates as a silicon avalanche diode that enters controlled breakdown when reverse voltage exceeds its VRWM of 11.1–13.7V, limiting transient energy via low-impedance conduction. Its 1.0ms 600W peak pulse rating follows the standard 10/1000μs waveform definition per IEC 61000-4-5.
Thermal design relies on its RθJA of 75°C/W and RθJL of 15°C/W, enabling stable operation up to +175°C junction temperature. The device exhibits fast response time (<1.0ns) and low leakage (≤5.0μA at VR), critical for protecting sensitive analog and digital inputs without loading normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive surge - meets IEC 61000-4-5 Level 4 immunity requirements. |
| Reverse Standoff Voltage (VRWM) | 11.1–13.7V - sets maximum continuous DC operating voltage before clamping initiates. |
| Clamping Voltage (VC) | 18.2V at 33A IPP - defines worst-case voltage seen by downstream circuit during surge event. |
| Breakdown Voltage (VBR) | 12.4V min @ 1.0mA - ensures reliable turn-on margin above VRWM with production tolerance. |
| Leakage Current (IR) | ≤5.0μA @ 11.1V - negligible bias current impact on low-power sensor or reference circuits. |
| Package | DO-15 - industry-standard axial leaded package compatible with through-hole PCB assembly and manual repair. |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), 0.4g weight, cathode band marking for polarity identification. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential rail in unidirectional TVS configuration. |
| Cathode | Reverse-biased clamping terminal | Connected to protected line; conducts avalanche current when voltage exceeds VRWM. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power dissipation | Supports robust protection against high-energy surges including lightning-induced transients on 24V industrial buses. |
| Glass-passivated die construction | Ensures stable electrical parameters and long-term reliability under humidity and thermal cycling stress. |
| Fast response time (<1.0ns) | Clamps transients before they propagate into sensitive downstream ICs such as microcontrollers or CAN transceivers. |
| RoHS-compliant lead finish | Enables compliance with environmental regulations without compromising solderability or intermetallic formation. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V DC input rail in programmable logic controller (PLC) power stage exposed to load dump and inductive switching noise. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp positive-going transients. Use Value: Limits surge voltage to ≤18.2V, preventing damage to upstream rectifier diodes and downstream DC-DC controllers rated for 20V max input. | Use Scenario: LIN bus line in door module subjected to ESD events and battery connection transients. IC Role / Device Role / Timing Role: Primary protection device on LIN data line, positioned before transceiver input. Use Value: Clamps ESD pulses to <18.2V within nanoseconds, preserving signal integrity and avoiding false wake-up or latch-up in LIN transceiver. |
| Telecom Remote Power Feeding | Medical Diagnostic Equipment Input |
Use Scenario: 48V phantom power feed to remote IP camera over PoE-like cabling prone to induced surges. IC Role / Device Role / Timing Role: First-stage overvoltage clamp on DC input before DC-DC isolation stage. Use Value: Absorbs up to 600W surge energy while maintaining clamped voltage below 20V, safeguarding isolated gate drivers and optocouplers. | Use Scenario: Front-end analog sensor interface in portable ultrasound unit connected to external probes. IC Role / Device Role / Timing Role: Low-leakage TVS on differential analog input lines to protect precision ADC front-end. Use Value: Adds <5.0μA leakage at 11.1V, preserving signal-to-noise ratio while suppressing >30A transients from probe cable coupling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-T | Same VRWM (11.1–13.7V) and VC (18.2V), but SMC package (higher thermal mass, 600W rating retained). | Surface-mount footprint replaces axial DO-15; requires rework of PCB layout and assembly process. | Select when board space is constrained and automated SMT assembly is preferred over through-hole. |
| P6KE13CA-T | Bidirectional variant with identical VRWM/VC specs but symmetric clamping for AC-coupled or floating lines. | Used where signal lines lack fixed DC bias (e.g., RS-485, audio lines), requiring clamping in both polarities. | Choose only if bidirectional protection is required; unidirectional P6KE13A-T offers lower cost and simpler polarity management in DC systems. |
Compared with SMBJ13A-T and P6KE13CA-T, the P6KE13A-T provides optimal cost-performance balance for fixed-polarity DC protection in legacy through-hole designs, with verified thermal performance in leaded mounting configurations and direct compatibility with existing DO-15 footprints.

FAQ
What is the maximum clamping voltage of P6KE13A-T at its rated peak pulse current?
The P6KE13A-T has a maximum clamping voltage (VC) of 18.2V at 33A peak pulse current (IPP), measured under the standard 1.0ms exponential decay waveform (10/1000μs). This value is guaranteed across the full operating temperature range and represents the upper limit of voltage imposed on protected circuitry during surge events.
Is P6KE13A-T suitable for automotive applications requiring AEC-Q101 qualification?
No - the P6KE13A-T is not AEC-Q101 qualified. While Diodes offers AEC-Q101-qualified TVS devices (e.g., in the DZxx family), the P6KE series is intended for industrial and commercial applications. For automotive use, consult Diodes' AEC-Q101-certified alternatives and confirm PPAP readiness with your local representative.
How does the DO-15 package affect thermal performance compared to SMC or SMA packages?
The DO-15 package delivers RθJA = 75°C/W and RθJL = 15°C/W, making it suitable for moderate-power surge absorption with adequate PCB copper area. Unlike surface-mount SMC packages, DO-15 relies on lead conduction for heat transfer; its thermal resistance increases significantly without proper lead length and copper land optimization per datasheet guidelines.
Can P6KE13A-T be used in bidirectional signal line protection?
No - P6KE13A-T is unidirectional and conducts only in reverse breakdown. For bidirectional protection (e.g., RS-485, USB, or AC-coupled lines), the bidirectional variant P6KE13CA-T must be used. Using P6KE13A-T on a floating or AC signal line risks forward conduction and permanent damage during negative excursions.
