Product details
Overview
P6KE8V2CA-B from Diodes Incorporated is a bidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 7.02V minimum breakdown voltage, 8.61V maximum clamping voltage at 50A peak pulse current, and 12.1V maximum clamping voltage under 50A 10/1000µs surge, housed in a DO-15 package for board-level ESD and lightning surge suppression in industrial power supplies.
For engineers reviewing the P6KE8V2CA-B datasheet, P6KE8V2CA-B pinout, P6KE8V2CA-B application, or P6KE8V2CA-B equivalent, this page delivers verified electrical parameters, DO-15 terminal mapping, bidirectional clamping behavior, thermal derating curves, and direct replacement guidance - all grounded in Diodes' DS21502 Rev. 20-4 specification.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with a reverse standoff voltage (VRWM) of 7.02V and a breakdown voltage (VBR) range of 7.79V–8.61V at 10mA test current. Its 12.1V clamping voltage (VC) at 50A IPP ensures predictable voltage limiting during transient events.
Designed for unidirectional and bidirectional configurations, it uses glass-passivated junction construction to achieve fast response time (<1ns), low leakage (≤200µA at VRWM), and stable performance across –55°C to +175°C operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10/1000µs surges without failure under defined thermal conditions |
| Clamping Voltage VC | 12.1V @ 50A - limits voltage seen by downstream circuitry during worst-case transients |
| Breakdown Voltage VBR | 7.79–8.61V @ 10mA - defines precise conduction onset threshold for bidirectional protection |
| Reverse Standoff VRWM | 7.02V - maximum continuous DC or RMS voltage before significant leakage begins |
| Peak Pulse Current IPP | 50.0A - maximum non-repetitive surge current the device can safely clamp |
| Leakage Current IR | ≤200µA @ VRWM - ensures minimal power loss and signal integrity in standby operation |
| Package | DO-15 - industry-standard axial leaded package with 0.4g mass and UL 94V-0 flammability rating |
Pinout & Package
The P6KE8V2CA-B is a two-terminal bidirectional TVS diode in a DO-15 molded plastic package with axial leads. No polarity marking is applied; terminals are functionally identical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional surge path | Either terminal serves as input/output for transient energy absorption in both directions |
| Lead 1 / Lead 2 | Thermal and mechanical interface | Plated copper leads provide solderable connection and conduct heat to PCB copper area per RθJL = 15°C/W |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated die construction | Enables stable VBR tolerance and long-term reliability under repeated surge stress |
| 600W peak pulse power rating | Supports IEC 61000-4-5 Level 4 (4kV line-to-line) surge immunity in compact form factor |
| Bidirectional configuration (suffix 'C') | Eliminates need for polarity-aware layout; protects AC-coupled or floating signal paths |
| RoHS-compliant lead finish | Meets EU Directive 2011/65/EU with full exemption documentation per Diodes' green policy |
Applications
| Industrial Power Input Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: 24V DC input rail in programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤12.1V, preventing damage to 12V-rated ICs while surviving 50A surges per IEC 61000-4-5. | Use Scenario: CAN bus power supply line in BCM modules subject to ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Bidirectional TVS on VBAT rail feeding CAN transceivers and MCU power domains. Use Value: Symmetric clamping ensures protection during negative-going pulses without requiring dual-device placement. |
| AC-DC Adapter Secondary Side | RS-485 Transceiver Interface |
Use Scenario: Output rectification stage of offline flyback adapters where output ripple and surge coexist. IC Role / Device Role / Timing Role: Parallel-connected TVS across secondary-side bulk capacitor to absorb reflected surge energy. Use Value: 7.02V VRWM allows safe operation with 5V/12V outputs while clamping spikes before they reach regulation circuitry. | Use Scenario: Data line protection for RS-485 transceivers in factory automation networks. IC Role / Device Role / Timing Role: Bidirectional shunt device across differential A/B lines referenced to ground. Use Value: Low 12.1V VC prevents receiver input overvoltage during ESD events (IEC 61000-4-2 ±8kV contact). |

FAQ
What does the 'C' suffix mean in P6KE8V2CA-B?
The 'C' suffix denotes a bidirectional configuration: the device clamps transient voltages symmetrically in both forward and reverse directions, with no cathode band marking. This enables use on AC-coupled lines or floating nodes without polarity constraints, unlike unidirectional variants (e.g., P6KE8V2A) which require correct anode/cathode orientation.
Is P6KE8V2CA-B still in active production?
No - Diodes Incorporated has officially discontinued the P6KE8V2CA-B. The datasheet (DS21502 Rev. 20-4, August 2024) explicitly states "OBSOLETE – PART DISCONTINUED". Aetrix Electronics maintains limited legacy stock and supports continuity planning, but new design-ins should consider qualified replacements.
How does P6KE8V2CA-B compare to SMAJ8.0CA?
P6KE8V2CA-B (DO-15, 600W) offers higher peak power than SMAJ8.0CA (SMA, 400W) but larger footprint and lower thermal efficiency. SMAJ8.0CA provides tighter VBR tolerance (8.0V min/9.1V max vs. 7.79V/8.61V) and surface-mount compatibility, making it preferable for space-constrained or automated assembly applications where 400W clamping suffices.
Can P6KE8V2CA-B be used in automotive AEC-Q200 applications?
While Diodes offers AEC-Q200-qualified TVS devices, the P6KE8V2CA-B is not AEC-Q200 certified. Its datasheet notes that automotive-grade parts require specific change control, PPAP capability, and IATF 16949 manufacturing - none of which apply to this obsolete DO-15 variant. For automotive use, consult Diodes' Automotive TVS portfolio (e.g., D3V3M1U series).
