Product details
Overview
P6KE16A-T from Diodes Incorporated is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 13.6V reverse standoff voltage (VRWM), 15.2V minimum breakdown voltage (VBR), 22.5V maximum clamping voltage (VC) at 27A 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 P6KE16A-T datasheet, P6KE16A-T pinout, P6KE16A-T application, or P6KE16A-T equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, 1.0ms 600W surge capability, unidirectional polarity, DO-15 thermal derating above +25°C, and compliance with IEC 61000-4-5 Level 4 surge immunity requirements.
Technical Context
This TVS operates as a voltage-clamped shunt protector: under normal conditions it presents <5µA leakage at 13.6V; during transients exceeding 15.2V, it avalanches rapidly (<1ns response) to clamp line voltage to ≤22.5V while diverting up to 27A of 8.3ms half-sine surge current. Its glass-passivated die ensures stable breakdown characteristics and long-term reliability under repeated surges.
The device is rated for -55°C to +175°C operating temperature, with thermal resistance of 75°C/W (junction-to-ambient) on standard PCB mounting and 15°C/W (junction-to-lead), enabling robust performance in high-temperature environments such as engine compartments or enclosed power converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive surge - sustains IEC 61000-4-5 combination wave (1.2/50μs voltage, 8/20μs current) without failure |
| Reverse Standoff Voltage | 13.6V - maximum continuous DC or RMS voltage before significant leakage; sets upper limit for protected circuit operating voltage |
| Breakdown Voltage | 15.2V min @ 1.0mA - guaranteed avalanche initiation threshold; ensures reliable triggering before downstream component damage |
| Clamping Voltage | 22.5V max @ 27A IPP - limits transient voltage seen by load; provides ≥3.5V margin below typical 24V system rail absolute max |
| Package | DO-15 - industry-standard axial leaded package with 0.4g mass, UL 94V-0 molded plastic, and 9.5mm lead length for 5.0W steady-state dissipation at TL=+75°C |
| Operating Temperature | -55°C to +175°C - supports under-hood automotive, industrial motor drives, and outdoor power equipment deployments |
Pinout & Package
DO-15 package: axial-leaded, glass-passivated silicon junction, molded black plastic body (UL 94V-0), cathode band marking for unidirectional polarity. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-voltage reference; completes shunt path during overvoltage events |
| Cathode | High-side connection point | Connected to protected line (e.g., 24V rail); blocks reverse current until breakdown threshold exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables single-device protection against IEC 61000-4-5 Level 4 (4kV/2kA) surges on 24V systems without parallel staging |
| Glass-passivated die construction | Eliminates moisture-induced parameter drift and improves long-term stability in humid or condensing environments |
| Fast response time (<1ns) | Clamps transients before sensitive downstream ICs (e.g., microcontrollers, CAN transceivers) experience overstress |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation; compatible with lead-free reflow and wave soldering processes |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
|
Use Scenario: 24V DC input stage of programmable logic controller (PLC) power supply exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary shunt clamping element placed directly across input terminals, upstream of EMI filter and bulk capacitor. Use Value: Limits transient voltage to 22.5V, preventing damage to upstream rectifier diodes and downstream DC-DC controllers rated for 28V absolute maximum. |
Use Scenario: LIN bus line protection in door module ECU subjected to battery reverse connection and jump-start spikes. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and chassis ground, triggered only during positive overvoltage events. Use Value: Clamps 100V/500ms load dump transients to ≤22.5V, preserving LIN transceiver integrity without interfering with bidirectional communication signaling. |
| Telecom DC Feeder Protection | Renewable Energy Charge Controller |
|
Use Scenario: -48V DC power feed line in remote base station cabinet subject to lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Reverse-polarity mounted TVS (cathode to -48V rail) providing negative-going surge suppression. Use Value: Withstands 100A 10/1000μs surge per Telcordia GR-1089-CORE, maintaining clamping below -55V to protect PMIC and FPGA power domains. |
Use Scenario: PV array input stage of solar charge controller exposed to rapid voltage reversals during partial shading or open-circuit faults. IC Role / Device Role / Timing Role: Unidirectional clamping device placed between PV+ and battery ground to absorb reverse-biased string voltage overshoots. Use Value: Absorbs 600W surge energy from 100V+ PV string transients, preventing gate oxide rupture in synchronous buck MOSFETs rated for 100V VDS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-T | Same VRWM (13.6V) and VC (22.5V), but SMB package (surface-mount), 600W rating, 27A IPP | Requires PCB real estate optimization; better suited for automated SMT assembly and higher-density layouts | Select when board space is constrained and reflow compatibility is required; verify thermal pad layout for 5.0W dissipation |
| P6KE16CA-T | Bidirectional variant: identical VRWM (13.6V), VBR (15.2V), VC (22.5V), but symmetrical clamping for AC or dual-polarity lines | Supports protection of differential buses (e.g., RS-485) or AC-coupled signals where negative transients occur | Select only if bidirectional surge immunity is required; unidirectional P6KE16A-T offers lower cost and simpler polarity management |
Compared with SMBJ16A-T, P6KE16A-T offers through-hole mechanical robustness and easier manual rework; compared with P6KE16CA-T, it delivers lower capacitance and avoids unnecessary bidirectional conduction in DC-only rails-reducing standby leakage and simplifying layout.

FAQ
Is P6KE16A-T still in active production?
No-P6KE16A-T is officially marked obsolete per Diodes Incorporated's DS21502 Rev. 20-4 (August 2024). However, Aetrix Electronics maintains verified legacy stock with full traceability and supports ongoing production for qualified designs under controlled obsolescence management protocols.
What is the maximum allowable surge repetition rate for P6KE16A-T?
The datasheet specifies "non-repetitive" 1.0ms pulses with duty cycle limited to 4 pulses per minute at TA = +25°C. Continuous or high-frequency surge exposure exceeds thermal limits; for repetitive transients, derating curves in Figure 4 must be applied based on ambient temperature and pulse interval.
Can P6KE16A-T be used in place of a Zener diode for voltage regulation?
No-it is not designed for continuous regulation. P6KE16A-T conducts heavily only during transient overvoltage events and lacks the stable dynamic impedance or low-noise characteristics required for precision DC regulation; use dedicated Zener regulators like BZX84-C15 for that function.
How does the DO-15 package affect thermal performance in high-power surge events?
With RθJA = 75°C/W on standard PCB mounting, the DO-15 package limits sustained power handling but remains effective for short-duration surges. For repeated 600W events, copper land area ≥40mm² and 9.5mm lead length are mandatory to achieve the rated 5.0W steady-state dissipation at TL = +75°C.
