Product details
Overview
P6KE150A-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 128V reverse standoff voltage (VRWM), 143V minimum breakdown voltage (VBR), 207V maximum clamping voltage (VC) at 2.9A peak pulse current, and DO-15 package construction with glass passivated die-used in industrial power supplies and automotive body control modules.
For engineers reviewing the P6KE150A-T datasheet, P6KE150A-T pinout, P6KE150A-T application, or P6KE150A-T equivalent, key selection criteria include clamping performance under 1.0ms 8/20μs surge, thermal resistance (RθJA = 75°C/W), unidirectional polarity marking, and RoHS-compliant lead finish for reflow compatibility.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR (143–158V), it avalanches into low-impedance conduction to divert surge energy away from downstream circuitry. Its 600W peak pulse power rating is defined at tP = 1.0ms per non-repetitive 10/1000μs waveform per REA standard.
Thermal design relies on junction-to-ambient dissipation (RθJA = 75°C/W) and steady-state power limit of 5.0W at TL = +75°C with 9.5mm lead length on 40mm² copper land. Response time is sub-nanosecond, enabling effective suppression of ESD and lightning-induced surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 1.0ms pulse - defines maximum single-event surge energy handling capability |
| Reverse Standoff Voltage (VRWM) | 128V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 143V min / 158V max @ 1.0mA - precise avalanche initiation threshold for reliable clamping onset |
| Clamping Voltage (VC) | 207V max @ 2.9A IPP - upper voltage limit imposed on protected circuit during surge |
| Peak Pulse Current (IPP) | 2.9A @ VC - actual surge current diverted through device under specified clamping condition |
| Thermal Resistance (RθJA) | 75°C/W - determines temperature rise above ambient under steady-state power dissipation |
| Package | DO-15 - axial-leaded plastic package rated UL 94V-0, 0.4g weight, compatible with wave/reflow soldering |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body with cathode band marking for unidirectional polarity identification. Leads are plated for MIL-STD-202 solderability; moisture sensitivity level is J-STD-020 Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path | Connected to system ground or low-impedance reference; completes clamping loop during avalanche |
| Cathode | Protected line input | Connected to line being protected (e.g., +12V rail); voltage referenced to anode during clamping |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 surges (4kV/2Ω) on 12–48V systems |
| Glass passivated die | Improves long-term reliability and stability of VBR under thermal cycling and humidity stress |
| Fast response time | Sub-nanosecond turn-on ensures clamping occurs before sensitive ICs experience overstress |
| RoHS-compliant lead finish | Lead-free plating supports Pb-free reflow profiles without compromising solder joint integrity |
| Unidirectional configuration | Prevents reverse-bias leakage on DC-coupled lines while allowing normal forward operation of downstream circuits |
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 transients. IC Role / Device Role / Timing Role: Primary shunt TVS placed upstream of DC-DC converter input filter. Use Value: Clamps 120V transients to ≤207V within nanoseconds, preventing MOSFET gate oxide failure and regulator latch-up. |
Use Scenario: LIN bus line interface in door module subjected to ESD and battery reversal events. IC Role / Device Role / Timing Role: Unidirectional TVS between LIN transceiver pin and chassis ground. Use Value: Blocks >128V reverse transients while maintaining <5μA leakage at 24V nominal, preserving bus signal integrity. |
| Telecom Remote Radio Unit | Medical Diagnostic Equipment Power Input |
Use Scenario: -48V DC feed line in outdoor base station radio unit vulnerable to induced lightning surges. IC Role / Device Role / Timing Role: Bidirectional protection not applicable; this unidirectional part used on positive rail only with separate grounding scheme. Use Value: Withstands 600W 10/1000μs surges up to 2.9A without degradation, verified per IEC 61000-4-5 Ed.3. |
Use Scenario: AC/DC adapter output stage supplying isolated patient-connected monitoring circuitry. IC Role / Device Role / Timing Role: Final-stage overvoltage clamp before LDO regulator input. Use Value: Limits fault voltage to 207V during surge, ensuring downstream isolation barrier remains within reinforced insulation test limits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-T | Same VRWM (128V) and VC (207V), but SMB package (surface-mount), lower PPK = 600W, RθJA = 40°C/W | Requires PCB real estate optimization; better thermal performance in compact layouts; no axial lead routing needed | Select for automated SMT assembly and improved thermal management where board space permits |
| P6KE150CA-T | Bidirectional version: identical VRWM/VBR/VC specs but symmetrical clamping for AC or floating lines | Used where line polarity is undefined or bidirectional signals (e.g., RS-485, CAN) require protection | Choose only if circuit lacks defined ground reference or handles AC-coupled signals |
Compared with P6KE150A-T, SMBJ150A-T offers superior thermal resistance and SMT compatibility but requires layout redesign, while P6KE150CA-T provides polarity-agnostic clamping at the cost of higher leakage in DC applications.

FAQ
Is P6KE150A-T still in active production?
No-Diodes Incorporated has officially discontinued the P6KE150A-T (document DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). However, Aetrix Electronics maintains legacy inventory with full traceability and supports ongoing production runs for qualified customers under controlled allocation.
What is the meaning of the 'A' suffix in P6KE150A-T?
The 'A' denotes unidirectional polarity: the device functions as a single-junction avalanche diode with cathode band marking, intended for DC line protection where reverse voltage must be blocked. It is distinct from the 'CA' suffix, which indicates bidirectional symmetry.
Can P6KE150A-T replace P6KE150CA-T in a circuit?
No-P6KE150A-T is unidirectional and will conduct heavily if reverse-biased beyond VRWM, whereas P6KE150CA-T clamps symmetrically in both directions. Substitution requires verifying line polarity, ground reference, and whether AC coupling or floating signals exist in the target application.
What is the maximum operating temperature for P6KE150A-T?
The junction and storage temperature range is –55°C to +175°C. Derated peak pulse power drops linearly above +25°C ambient; at +125°C ambient, only ~25% of rated 600W pulse power is sustainable due to thermal rolloff per Figure 4 in DS21502.
