Product details
Overview
P6KE150CA-T from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. 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 with glass passivated die construction. Used in industrial power supplies to clamp ESD and lightning-induced surges.
For engineers reviewing the P6KE150CA-T datasheet, P6KE150CA-T pinout, P6KE150CA-T application, or P6KE150CA-T equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, 600W peak pulse power handling under 1.0ms waveform, and DO-15 thermal derating above +25°C ambient.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass passivated junction ensures stable VBR tolerance (±5% typical) and low leakage (<5µA @ VRWM) at elevated temperatures up to +175°C junction.
The device responds within <1.0ns to transients, clamping voltages to ≤207V during 1.0ms 2.9A pulses while maintaining low dynamic impedance (~71Ω). Thermal resistance from junction to ambient is 75°C/W on standard PCB mounting, requiring attention to copper land area for sustained surge duty cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W for 1.0ms non-repetitive pulse - defines maximum transient energy absorption capability |
| Reverse Standoff Voltage | 128V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 143V min @ 1mA - onset of avalanche conduction; tight ±5% tolerance ensures predictable triggering |
| Clamping Voltage | 207V max @ 2.9A IPP - limits protected circuit voltage during surge, critical for downstream IC survival |
| Package | DO-15 - industry-standard axial leaded package with 0.4g mass, UL 94V-0 rated molded plastic body |
| Operating Temperature | -55°C to +175°C - supports under-hood automotive and industrial environments without derating loss |
| RoHS Compliance | Lead-free, halogen-free, antimony-free - meets EU Directive 2011/65/EU with full exemption documentation |
Pinout & Package
DO-15 package: axial-leaded, cylindrical epoxy body, cathode band not marked on bidirectional version (P6KE150CA-T); leads are solderable per MIL-STD-202 Method 208, 9.5mm lead length standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative-going surges; symmetrical with cathode in bidirectional operation |
| Cathode | Transient current entry (positive polarity) | Conducts during positive-going surges; identical electrical behavior to anode due to bidirectional structure |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power rating | Enables robust protection against IEC 61000-4-5 Level 4 (4kV surge) on 48V industrial buses |
| Glass passivated die construction | Ensures long-term parameter stability and reduced parameter drift over temperature and life |
| Bidirectional configuration | Eliminates need for polarity-aware layout; protects AC signals, differential buses, and floating grounds |
| Fast response time <1.0ns | Clamps transients before sensitive downstream components experience overstress |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes voltage overshoot during surge, reducing stress on protected ICs' absolute maximum ratings |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA-T | Same VRWM (128V) and VC (207V), but 600W in SMB package - surface-mount, lower RθJA (50°C/W) | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs | Select when board space is constrained and thermal management via copper pour is feasible |
| P6SMB150CA-T | Identical electrical specs, same SMB package, but manufactured by STMicroelectronics - different qualification traceability | No functional difference; may require separate AEC-Q200 requalification for automotive programs | Choose only if dual-sourcing strategy mandates multi-vendor BOM or existing ST-based design reuse |
Compared with P6KE150CA-T, SMBJ150CA-T offers superior thermal performance in compact layouts but sacrifices mechanical robustness and lead-forming flexibility; P6SMB150CA-T provides second-source assurance but introduces supply chain validation overhead for qualified automotive programs.

FAQ
Is P6KE150CA-T still in production?
No - Diodes Incorporated has officially discontinued the P6KE150CA-T and entire P6KE series (DS21502 Rev. 20–4 states "OBSOLETE – PART DISCONTINUED"). However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle management support including last-time buy planning and cross-reference guidance.
What is the meaning of the 'C' suffix in P6KE150CA-T?
The 'C' suffix denotes bidirectional configuration: P6KE150CA-T conducts symmetrically for both positive- and negative-polarity transients, unlike unidirectional P6KE150A-T which clamps only positive surges and blocks negative voltage beyond its VRRM rating. No cathode band marking is used on bidirectional versions.
Can P6KE150CA-T replace P6KE150A-T in a circuit?
Only if the application requires bidirectional protection - P6KE150CA-T cannot substitute for P6KE150A-T in circuits relying on DC blocking of reverse polarity, such as single-supply rail clamping where negative voltage must be blocked. Electrical parameters (VRWM, VBR, VC) are identical, but polarity behavior differs fundamentally.
What is the maximum number of 2.9A surges P6KE150CA-T can withstand?
Per Figure 6 in DS21502, P6KE150CA-T withstands ≥1000 cycles of 2.9A 60Hz half-sine surges at TJ = 25°C. Derating applies above ambient: Figure 4 shows 50% peak power allowed at +125°C ambient, limiting repetitive surge capability unless heatsinking or forced airflow is implemented.
