Product details
Overview
P6KE180A-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 154V reverse standoff voltage (VRWM), 171V minimum breakdown voltage (VBR), 246V maximum clamping voltage (VC) at 2.4A peak pulse current (IPP), and DO-15 package with glass-passivated junction - used in industrial power supplies, automotive body control modules, and telecom interface protection.
For engineers reviewing the P6KE180A-T datasheet, P6KE180A-T pinout, P6KE180A-T application, or P6KE180A-T equivalent, key selection criteria include clamping voltage margin relative to system rail, 1.0ms pulse power derating above +25°C, unidirectional polarity marking, and compatibility with IEC 61000-4-2/4-4/4-5 surge test requirements.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device: under normal bias it presents <5.0µA leakage at VRWM; when transient voltage exceeds VBR (171V min), it avalanches rapidly (<1ns response) to clamp the line at ≤246V. Its 600W peak pulse rating applies to a 10/1000µs waveform per standard IEC 61000-4-5.
The DO-15 package enables through-hole mounting on PCBs with thermal relief pads; its RθJA of 75°C/W and 5.0W steady-state dissipation at TL=+75°C define safe continuous operation limits. Lead finish is lead-free and RoHS-compliant per EU Directive 2011/65/EU.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W @ 1.0ms non-repetitive pulse - defines maximum single-event surge energy absorption capability |
| Reverse Standoff Voltage | 154V - maximum continuous DC or RMS voltage the device blocks without significant leakage |
| Breakdown Voltage | 171V min / 189V max @ 1.0mA - voltage at which avalanche conduction begins; sets clamping onset threshold |
| Clamping Voltage | 246V max @ 2.4A IPP - maximum voltage seen by protected circuit during specified surge event |
| Peak Pulse Current | 2.4A @ 10/1000µs waveform - peak current the device safely conducts while clamping within spec |
| Leakage Current | ≤5.0µA @ 154V - ensures minimal power loss and no false triggering in nominal operating conditions |
| Package | DO-15 - axial-leaded, molded plastic case rated UL 94V-0; supports manual or wave soldering |
Pinout & Package
DO-15 package: axial-leaded, cylindrical molded plastic body (25.4mm length, 5.5–7.62mm diameter), cathode band marked on one end. 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; forms return path during clamping |
| Cathode | High-side connection point | Connected to protected line; avalanche conduction initiates here when VRWM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV line-to-ground) on 24V/48V systems |
| Glass-passivated junction | Improves long-term reliability and moisture resistance vs. epoxy-passivated alternatives |
| Fast response time (<1ns) | Clamps transients before downstream ICs experience damaging overvoltage stress |
| RoHS-compliant lead finish | Meets global environmental compliance requirements without compromising solderability or thermal performance |
| Unidirectional polarity | Prevents reverse-bias conduction in DC-coupled applications; cathode band provides clear orientation |
Applications
| Industrial Power Supply 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 noise. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input rail and ground, upstream of DC-DC converter. Use Value: Limits transient excursions to ≤246V, preventing damage to 30V-rated MOSFETs and gate drivers in the front-end stage. |
Use Scenario: LIN bus line protection in door module ECU subjected to battery disconnect spikes and ESD events. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and chassis ground, referenced to vehicle battery. Use Value: Clamps 100V+ load dump transients to safe levels while maintaining <5µA leakage to avoid bus contention. |
| Telecom Interface Protection | Renewable Energy Inverter DC Link |
Use Scenario: RS-485 transceiver port on base station remote radio unit powered from -48V telecom supply. IC Role / Device Role / Timing Role: Line-to-ground TVS on A/B differential pair, with common-mode choke filtering. Use Value: Absorbs 600W surges without degrading signal integrity; clamping voltage stays below transceiver absolute max rating. |
Use Scenario: DC link between PV array and MPPT controller in solar microinverter, subject to lightning-induced surges. IC Role / Device Role / Timing Role: Parallel-connected TVS across 300–400V DC bus to limit overvoltage during fast-rising transients. Use Value: Withstands 2.4A peak pulses while holding bus voltage ≤246V - well below 450V capacitor rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A-T | Same VRWM (154V) and VC (246V), but SMC package (surface-mount); 600W rating, 2.4A IPP | Requires PCB rework for SMT assembly; lower profile, better high-frequency impedance than DO-15 | Select when board space is constrained and automated assembly is preferred over through-hole. |
| P6KE180CA-T | Bidirectional version: same VRWM (154V), symmetric clamping (±246V), identical DO-15 package and 600W rating | Supports AC-coupled or floating signal lines (e.g., Ethernet PHY, audio), not DC rails | Choose only for bidirectional surge paths where polarity reversal must be suppressed in both directions. |
Compared with P6KE180A-T, SMBJ180A-T offers surface-mount compatibility at identical electrical performance, while P6KE180CA-T enables AC-line protection but sacrifices DC-rail blocking capability due to symmetrical conduction.

FAQ
Is P6KE180A-T still in active production?
No - Diodes Incorporated has officially discontinued the P6KE180A-T (document DS21502 Rev. 20-4 states "OBSOLETE – PART DISCONTINUED"). However, Aetrix Electronics maintains verified legacy stock with full traceability and supports extended-life design requirements through controlled distribution channels.
What is the difference between P6KE180A-T and P6KE180CA-T?
P6KE180A-T is unidirectional (anode-to-cathode conduction only), with cathode band marking; P6KE180CA-T is bidirectional (symmetric ±154V standoff), marked without polarity band. Both share identical VRWM, VBR, VC, and 600W rating, but differ in conduction directionality and application scope.
Can P6KE180A-T be used in place of a 180V Zener diode?
No - though both regulate voltage, P6KE180A-T is optimized for transient suppression (600W pulse, 2.4A IPP), not steady-state regulation. Its leakage is higher than precision Zeners, and it lacks tight VZ tolerance; use only for surge clamping, not voltage reference.
What is the maximum ambient temperature for continuous operation?
The device's RθJA is 75°C/W, and its steady-state power dissipation is rated at 5.0W at TL = +75°C. For continuous operation, ambient temperature must be limited to ensure junction temperature remains ≤+175°C - typically ≤+70°C with adequate PCB copper area and airflow.
