Product details
Overview
P6KE8V2A 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 7.02V reverse standoff voltage (VRWM), 7.79V minimum breakdown voltage (VBR), 12.1V maximum clamping voltage (VC) at 50A peak pulse current, and DO-15 glass-passivated package - deployed in automotive body control modules to suppress load-dump and inductive switching transients.
For engineers reviewing the P6KE8V2A datasheet, P6KE8V2A pinout, P6KE8V2A application, or P6KE8V2A equivalent, this page delivers verified electrical parameters, mechanical package data, clamping performance under 10/1000µs surge, thermal derating curves, and direct alternatives with documented voltage and current mismatches - all critical for ESD/surge co-design and AEC-Q101-compliant system validation.
Technical Context
This unidirectional TVS operates as a voltage-clamped shunt protector: it remains high-impedance below VRWM (7.02V), enters avalanche breakdown between 7.79V–8.61V (VBR min/max), and clamps transients to ≤12.1V at 50A IPP. Its 1.0ms pulse width rating aligns with IEC 61000-4-5 surge test profiles.
Constructed with glass-passivated silicon die in a DO-15 molded plastic case (UL 94V-0), it achieves fast response time (<1.0ns), low junction-to-lead thermal resistance (15°C/W), and supports steady-state dissipation of 5.0W at TL = +75°C - enabling reliable placement near connectors or power entry points without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W (1.0ms 10/1000µs waveform; defines maximum transient energy absorption capability) |
| Reverse Standoff Voltage | 7.02V (maximum continuous DC or RMS voltage before leakage exceeds 200µA; sets operating rail margin) |
| Breakdown Voltage | 7.79V–8.61V (avalanche onset range at 10mA IT; ensures predictable turn-on during overvoltage events) |
| Clamping Voltage | 12.1V @ 50A IPP (maximum voltage seen by protected circuit during full-rated surge; determines downstream IC survivability) |
| Peak Pulse Current | 50.0A (maximum non-repetitive surge current it can divert without failure; validates IEC 61000-4-5 Level 4 compliance) |
| Junction-to-Lead RθJL | 15°C/W (enables thermal design with short lead traces; supports 5.0W steady-state dissipation at TL = +75°C) |
| Package | DO-15 (industry-standard axial-leaded package; compatible with through-hole assembly and manual repair) |
Pinout & Package
DO-15 package: axial-leaded, molded plastic body (UL 94V-0), cathode band marking on unidirectional variant. Dimensions: length 25.4mm max, body diameter 5.5–7.62mm, lead diameter 0.686–0.889mm, lead spacing 2.6–3.6mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during reverse-biased surge | Connected to protected line; carries full IPP during clamping event |
| Cathode | Reference terminal / ground reference | Connected to system ground or low-impedance return path; defines polarity and clamping threshold |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse power | Supports robust protection against ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 surges up to 4kV |
| Glass-passivated die construction | Ensures stable VBR over temperature and long-term reliability in humid or contaminated environments |
| Fast response time (<1.0ns) | Activates before sensitive downstream components (e.g., MCU I/O, CAN transceivers) experience overstress |
| RoHS-compliant lead finish | Enables lead-free reflow compatibility and meets automotive ELV directive requirements |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12V battery-fed ECUs exposed to load-dump transients (up to 60V, 400ms) and alternator ripple. IC Role / Device Role: Primary shunt clamp placed at power entry point before LDO or DC-DC converter. Use Value: Limits voltage to ≤12.1V during 50A surge, preventing damage to 16V-rated input capacitors and regulator ICs. |
Use Scenario: 4–20mA current-loop sensors connected to PLC analog inputs in factory-floor environments. IC Role / Device Role: Line-side TVS on sensor signal wire to suppress EFT bursts and induced lightning surges. Use Value: Clamps transients to safe levels while maintaining <200µA leakage at 7.02V, avoiding loop-current error. |
| Consumer USB Power Adapter Input | Telecom DSL Line Protection |
Use Scenario: Secondary-side 5V rail in wall adapters subjected to conducted surges via AC mains coupling. IC Role / Device Role: Final-stage overvoltage guard before USB port controller or charging IC. Use Value: Absorbs 600W pulses without degradation, preserving 5V rail integrity during EN 61000-4-5 testing. |
Use Scenario: DSL line card interface exposed to longitudinal surges on twisted-pair copper lines. IC Role / Device Role: Unidirectional shunt protector on tip/ring pair referenced to chassis ground. Use Value: Provides low-capacitance (<100pF) clamping with 12.1V VC, minimizing signal distortion at 1–30MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | Lower PPK (600W same), but smaller SMB package (surface-mount); VRWM = 8.0V, VC = 12.0V @ 43.5A | Requires PCB real estate optimization; unsuitable for through-hole legacy designs or high-temperature lead-solder processes | Select when board space is constrained and reflow assembly is used; verify thermal pad layout for 5.0W dissipation. |
| P6KE8V2CA | Bidirectional variant; identical VRWM/VBR/VC specs but symmetric clamping for AC-coupled or floating lines | Used where signal polarity is undefined (e.g., RS-485, audio lines); doubles capacitance vs. unidirectional version | Choose only if bidirectional protection is required; avoid in DC power rails due to unnecessary leakage path. |
Compared with P6KE8V2A, SMBJ8.0A offers SMT compatibility at the cost of reduced surge margin (43.5A vs. 50A), while P6KE8V2CA provides polarity-agnostic clamping but sacrifices leakage performance and adds parasitic capacitance - making the original unidirectional DO-15 variant optimal for cost-sensitive, high-reliability DC rail protection.

FAQ
Is P6KE8V2A RoHS compliant and halogen-free?
Yes, P6KE8V2A features a lead-free finish and complies with EU RoHS Directive 2011/65/EU. Diodes Incorporated confirms it meets their internal "Green" definition, including antimony- and halogen-free materials per specification DS21502 Rev. 20–4.
What is the maximum operating temperature for P6KE8V2A?
P6KE8V2A has an operating and storage temperature range of –55°C to +175°C. Its thermal resistance values (RθJA = 75°C/W, RθJL = 15°C/W) allow full 600W pulse operation at TA ≤ +25°C, with linear derating above that per Figure 4 in the datasheet.
Can P6KE8V2A be used in AEC-Q101 qualified designs?
P6KE8V2A itself is not AEC-Q101 certified, but Diodes Incorporated states that automotive-grade variants (with PPAP capability and IATF 16949 manufacturing) are available upon request - contact Diodes or Aetrix for qualified equivalents meeting AEC-Q101 stress test requirements.
How does P6KE8V2A differ from P6KE8V2CA?
P6KE8V2A is unidirectional (cathode-banded), optimized for DC rail protection with lower leakage (<200µA at VRWM). P6KE8V2CA is bidirectional (no cathode band), providing symmetrical clamping for AC or floating signals but with doubled IR limit and higher capacitance - unsuitable for DC bias applications.
