Product details
Overview
P6KE8.2CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 8.2V, clamps transients to ≤12.5V at 200A peak surge current, and delivers sub-5ns response time - critical for safeguarding automotive ECUs, industrial I/O interfaces, and LED driver circuits against ESD and inductive switching spikes.
For engineers reviewing the P6KE8.2CA datasheet, P6KE8.2CA pinout, P6KE8.2CA application, or P6KE8.2CA equivalent, key selection criteria include its bidirectional DO-15 package, 6.63V stand-off voltage, <1μA leakage at rated VWM, AEC-Q101 qualification (H-suffix variant), and compatibility with 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE8.2CA operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior - both anodes tied internally to form a center-tapped structure enabling equal forward/reverse conduction. Its low dynamic impedance (<0.1Ω typical) ensures minimal voltage overshoot during fast transients, while junction temperature range (–55°C to +175°C) supports under-hood and industrial ambient operation.
Electrical characteristics are fully specified for both polarities per ANSI/IEEE C62.35, with VBR min/max (7.38V–9.02V) measured at 10mA test current and VC limited to 12.5V at IPP = 200A. The device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements, confirming suitability for high-reliability soldered assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W at 10/1000μs waveform - sustains single high-energy surges without failure |
| Stand-Off Voltage VWM | 6.63V - maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage VBR | 7.38V–9.02V at 10mA - defines reliable avalanche initiation threshold in both directions |
| Clamping Voltage VC | 12.5V at 200A IPP - limits protected circuit voltage during worst-case surge event |
| Leakage Current ID | <1μA at 6.63V - negligible standby power loss and signal integrity impact |
| Response Time | <5.0ns - enables protection of high-speed digital and analog interfaces |
| Junction Temp Range | –55°C to +175°C - supports automotive under-hood and industrial control environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case with UL 94V-0 rating. Cathode band marking omitted due to bidirectional symmetry; polarity is non-directional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 / Cathode 1 | Terminal A | One end of symmetrical avalanche junction - connects to line being protected |
| Anode 2 / Cathode 2 | Terminal K | Other end of symmetrical junction - connects to reference (GND or return) |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC performance in both polarities - eliminates need for polarity-aware layout |
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensors |
| Low clamping ratio | VC/VBR ≈ 1.5 - tight voltage margin between trigger and clamp ensures upstream ICs stay within safe operating area |
| Tin-plated leads | Solderable per J-STD-002 - compatible with standard reflow and wave solder processes without lead-free concerns |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets environmental compliance requirements for RoHS and WEEE programs |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12V battery-supplied microcontrollers and CAN transceivers from load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed across VCC-GND rail, responding within 5ns to suppress >100V spikes. Use Value: Prevents latch-up or permanent damage to 5V/3.3V logic ICs by limiting rail voltage to ≤12.5V during ISO 7637-2 Pulse 5a events. |
Use Scenario: Shielding 4–20mA current-loop sensor inputs from EFT bursts and field wiring induced surges. IC Role / Device Role / Timing Role: Bidirectional shunt element on analog input path, clamping both positive and negative transients symmetrically. Use Value: Maintains signal fidelity and prevents ADC saturation or op-amp rail-to-rail excursion during IEC 61000-4-4 Level 4 testing. |
| LED Driver Output Protection | RS-485 Transceiver Line Protection |
Use Scenario: Safeguarding constant-current LED drivers from inductive kickback when driving solenoid-based dimming circuits. IC Role / Device Role / Timing Role: Parallel-connected TVS across output terminals, absorbing energy from L·di/dt spikes during MOSFET turn-off. Use Value: Eliminates need for snubber networks while ensuring driver IC survives repeated 600W surge events per 10/1000μs profile. |
Use Scenario: Guarding RS-485 transceiver bus pins (A/B) against lightning-induced surges and ground potential differences. IC Role / Device Role / Timing Role: Differential-mode TVS pair (one P6KE8.2CA across A-GND, another across B-GND) providing balanced clamping. Use Value: Enables compliance with IEC 61000-4-5 Level 2 (1kV line-earth) without compromising data integrity or common-mode rejection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ8.0CA | Same DO-214AC package; slightly lower VBR (7.22–8.88V); identical 600W rating and 12.5V VC | Not AEC-Q101 qualified; intended for commercial/industrial use only | Select when automotive qualification is not required and board space allows SMA footprint |
| ON Semiconductor 1.5KE8.2CA | Higher power rating (1500W); larger DO-201AD package; VBR 7.38–9.02V; VC 12.5V at 120A | Over-specified for 600W needs; requires PCB layout change and higher cost | Choose only if system-level surge testing exceeds IEC 61000-4-5 Level 4 or demands extended lifetime under repetitive stress |
Compared with SMAJ8.0CA and 1.5KE8.2CA, the P6KE8.2CA uniquely balances AEC-Q101 compliance, DO-15 compactness, and precise 600W/12.5V clamping - making it optimal for space-constrained automotive modules where qualification and thermal reliability are mandatory.

FAQ
What does the 'CA' suffix indicate in P6KE8.2CA?
The 'CA' suffix in P6KE8.2CA denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., P6KE8.2A), the CA version has no cathode marking and is used where polarity of transient events cannot be guaranteed, such as across differential bus lines or AC-coupled signals. This is confirmed in TSC's P6KE Series documentation, Section "Devices for Bipolar Applications".
Is P6KE8.2CA AEC-Q101 qualified?
Yes, P6KE8.2CA is AEC-Q101 qualified when ordered with the 'H' suffix (i.e., P6KE8.2CAH). Per TSC's Ordering Information (Page 4), the 'H' designation indicates AEC-Q101 qualification, and P6KE8.2CA falls within the voltage range (6.8V–440V) eligible for this qualification - excluding only P6KE6V8A through P6KE9V1A. Standard P6KE8.2CA without 'H' is not certified.
What is the maximum clamping voltage of P6KE8.2CA at rated surge current?
The maximum clamping voltage (VC) of P6KE8.2CA is 12.5V at a peak pulse current (IPP) of 200A, tested with a 10/1000μs waveform. This value is specified in the Electrical Specifications table (Page 2) and represents the upper limit of voltage seen by downstream circuitry during a full-rated surge event - a critical parameter for ensuring protected ICs remain within absolute maximum ratings.
Can P6KE8.2CA replace P6KE8.2A in an existing design?
No - P6KE8.2CA cannot directly replace P6KE8.2A without verification. While both share the same breakdown voltage range (7.38–9.02V) and clamping voltage (12.5V), P6KE8.2A is unidirectional and requires correct cathode orientation, whereas P6KE8.2CA is bidirectional with no polarity marking. Swapping may cause incorrect clamping behavior in DC-biased circuits or violate layout assumptions. Always validate circuit topology and transient directionality before substitution.
What is the leakage current specification for P6KE8.2CA at its stand-off voltage?
P6KE8.2CA exhibits a maximum reverse leakage current (ID) of 1μA at its stand-off voltage (VWM) of 6.63V, measured at TA = 25°C. This ultra-low leakage minimizes power loss in always-on systems and avoids false triggering in high-impedance sensing nodes - a key advantage over higher-leakage alternatives like older 1N6267-series TVS diodes.
