Product details
Overview
P6KE8V2CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust ESD and surge protection in power rails and signal lines. It features a 8.2 V nominal breakdown voltage, 600 W peak pulse power rating at 10/1000 µs, clamping voltage of 12.1 V at 200 A peak surge current, and DO-204AC (DO-15) axial package - used in automotive lighting control modules to protect CAN transceiver power inputs against load dump and ISO 7637-2 pulses.
For engineers reviewing the P6KE8V2CA datasheet, P6KE8V2CA pinout, P6KE8V2CA application, or P6KE8V2CA equivalent, key selection criteria include bidirectional clamping capability, low dynamic impedance (<1 Ω typical), sub-5 ns response time, <1 µA leakage above 7.02 V standoff voltage, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE8V2CA operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - both anodes tied internally to form a common cathode structure. Its junction exhibits low dynamic impedance (typically <0.8 Ω), enabling rapid voltage clamping during fast transients such as EFT (IEC 61000-4-4) and ESD (IEC 61000-4-2).
It delivers 600 W peak pulse power handling per 10/1000 µs waveform, with thermal derating starting at 25 °C ambient and full derating to zero at 175 °C junction temperature. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements, supporting long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 8.2 V - defines rated standoff voltage threshold where clamping initiates under surge conditions |
| Breakdown Voltage VBR | 7.79–8.61 V @ 10 mA - verified avalanche conduction range ensuring predictable turn-on across production lot |
| Standoff Voltage VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin below VBR |
| Clamping Voltage VC | 12.1 V @ 200 A - limits downstream circuit voltage during worst-case 10/1000 µs surge, protecting 12 V logic rails |
| Peak Pulse Power PPK | 600 W - sustains single high-energy transients like ISO 7637-2 Pulse 1 (inductive switch-off) without failure |
| Junction Temperature Range | −55 °C to +175 °C - supports operation in engine bay and under-hood automotive applications |
| Response Time | <5.0 ns - enables suppression of fast-rising ESD events before sensitive ICs experience overstress |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, molded plastic case with pure tin-plated leads solderable per J-STD-002. Cathode band marking denotes polarity for unidirectional variants; P6KE8V2CA is bidirectional and marked with part number only (no polarity band).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode | Common terminal (center node) | Internally connected junction point enabling symmetrical bidirectional clamping in either direction |
| Anode 2 | Second terminal | Forms mirror-symmetric path with Anode 1 - no functional distinction; interchangeable in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, mechanical shock, and humidity testing per stress test plan |
| Low dynamic impedance | Typically <0.8 Ω - minimizes voltage overshoot during high di/dt surges, improving protection margin |
| UL Recognized (E326243) | Confirms flame-retardant molding compound and electrical safety compliance for end-equipment certification |
| Halogen-free construction | Meets IEC 61249-2-21 - supports RoHS-compliant manufacturing and environmentally responsible disposal |
Applications
| Automotive Lighting Control | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Protecting LED driver IC power inputs from load dump transients in 12 V vehicle lighting systems. IC Role / Device Role: Primary overvoltage clamp on VCC rail upstream of DC-DC converter input. Use Value: Limits voltage to ≤12.1 V during ISO 7637-2 Pulse 5a (load dump), preventing latch-up or burnout of 16 V-rated regulators. |

IC Role / Device Role: Secondary TVS stage after primary common-mode choke, placed directly at connector. Use Value: Responds in <5 ns to ±15 kV contact ESD (IEC 61000-4-2), limiting peak voltage to 12.1 V before USB PD controller IC. |
Use Scenario: Protecting auxiliary 5 V supply rail in utility smart meters exposed to lightning-induced surges on AC mains input. IC Role / Device Role: Final-stage clamping device after MOV and fuse, located at isolated DC-DC secondary side. Use Value: Absorbs residual 600 W surge energy post-MOV clipping, ensuring downstream microcontroller remains within 5.5 V absolute max 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 |
|---|---|---|---|
| SMBJ8.0CA (Bourns) | Same 8.0 V nominal, 600 W rating, but SMB package (surface-mount); lower clamping voltage (12.0 V @ 22.5 A) | Requires PCB rework for SMT vs. through-hole; better suited for space-constrained consumer electronics | Select when board real estate is limited and automated assembly is preferred over manual thru-hole insertion |
| 1.5KE8.2CA (ON Semiconductor) | Identical DO-15 package and 8.2 V rating, but 1500 W rating (1.5 kW); higher clamping voltage (13.4 V @ 112 A) | Over-spec'd for most 600 W use cases; may require larger trace widths and heatsinking due to higher energy dissipation | Choose only if system-level surge testing requires >600 W margin or legacy design reuse mandates 1.5KE footprint compatibility |
Compared with SMBJ8.0CA and 1.5KE8.2CA, the P6KE8V2CA offers optimal balance of proven automotive qualification (AEC-Q101), axial through-hole manufacturability, and precise 8.2 V clamping - making it ideal for cost-sensitive, high-reliability 12 V industrial and automotive subsystems where leaded assembly remains standard.

FAQ
What is the exact breakdown voltage range for P6KE8V2CA?
The P6KE8V2CA has a guaranteed breakdown voltage (VBR) range of 7.79 V to 8.61 V at 10 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping onset across production lots and supports reliable design margining in 12 V systems where the P6KE8V2CA is commonly deployed.
Is P6KE8V2CA AEC-Q101 qualified?
Yes, the P6KE8V2CA is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's official documentation and ordering code suffix "H" (P6KE8V2CAH). This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock, validating its suitability for automotive under-hood and body-control module applications.
What does the "CA" suffix mean in P6KE8V2CA?
The "CA" suffix in P6KE8V2CA explicitly denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions. Unlike "A"-suffixed unidirectional variants (e.g., P6KE8V2A), the CA version has no cathode band marking and functions identically regardless of voltage polarity applied across its terminals.
Can P6KE8V2CA replace P6KE8.2CA in existing designs?
Yes, P6KE8V2CA is functionally identical to P6KE8.2CA - both denote the same 8.2 V bidirectional TVS device in the P6KE series. The "V2" notation is a manufacturer-specific marking variant (e.g., used in tape-and-reel packaging), not a parametric difference; all electrical specs, package, and qualification status match exactly for the P6KE8V2CA and P6KE8.2CA.
What is the maximum clamping voltage of P6KE8V2CA under surge conditions?
The P6KE8V2CA clamps to a maximum of 12.1 V when subjected to a 200 A peak surge current with a 10/1000 µs waveform - as specified in Taiwan Semiconductor's official electrical characteristics table. This value defines the upper voltage limit imposed on protected circuits during worst-case transients, critical for ensuring downstream ICs remain within absolute maximum ratings.
