Product details
Overview
P6KE8.2C from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for clamping high-energy ESD and surge transients across power and signal lines. It features a nominal breakdown voltage of 8.2V, maximum clamping voltage of 12.5V at 200A peak surge current, and DO-204AC (DO-15) axial package - deployed in automotive lighting control, industrial sensor interfaces, and USB/RS-485 port protection.
For engineers reviewing the P6KE8.2C datasheet, P6KE8.2C pinout, P6KE8.2C application, or P6KE8.2C equivalent, key selection criteria include bidirectional clamping capability, 12.5V VC@200A, -55°C to +175°C operating junction temperature, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE8.2C operates as a silicon avalanche diode with symmetrical bidirectional conduction, enabling protection against both positive and negative polarity transients without external polarity management. Its 10/1000μs waveform surge rating of 600W and sub-5ns response time ensure fast suppression of electrical fast transients (EFT) per IEC 61000-4-4.
Designed for unclamped operation up to 6.63V standoff voltage (VWM), it maintains <1μA reverse leakage above 10V and exhibits a 0.065%/°C temperature coefficient of VBR - supporting stable clamping performance across extended ambient ranges in engine control units and motor drive circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.38V / 9.02V - defines guaranteed avalanche onset range under 10mA test current; ensures consistent turn-on across production lots |
| VWM | 6.63V - maximum continuous reverse working voltage; sets safe DC bias margin before leakage rises significantly |
| VC@IPP | 12.5V @ 200A - peak clamped voltage during 10/1000μs surge; determines protected circuit's maximum overvoltage exposure |
| PPK | 600W - non-repetitive surge power handling; supports single-event lightning-induced surges per IEC 61000-4-5 Level 3 |
| TJ max | +175°C - maximum junction temperature; enables placement near heat-generating components in enclosed automotive modules |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package; compatible with through-hole reflow and wave soldering per J-STD-002 |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional variants; P6KE8.2C is bidirectional and marked without polarity indicator - terminals are functionally symmetric.

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 | Lower PPK (600W same), but SMB package (surface-mount); VC = 12.3V @ 32.4A - lower surge current rating | Preferred for space-constrained PCBs; unsuitable for 200A-level surges requiring P6KE8.2C's DO-15 thermal mass | Select SMBJ8.0CA only when board area is limited and surge threat level is ≤30A (e.g., consumer USB ports) |
| 1.5KE8.2C | Same DO-204AC package and bidirectional function; lower PPK (1500W vs. 600W) - actually higher rating; VC = 13.4V @ 113A | Higher clamping voltage reduces protection margin for low-voltage ICs; better suited for 24V industrial systems than 5V/12V automotive | Choose 1.5KE8.2C when higher surge energy tolerance is needed and 13.4V clamping is acceptable for downstream 15V-rated components |
Compared with SMBJ8.0CA and 1.5KE8.2C, the P6KE8.2C delivers optimal balance of 200A surge handling, 12.5V clamping, and DO-15 thermal robustness - making it preferred for automotive and industrial applications where physical mounting stability and repeat surge endurance are critical.

FAQ
What is the maximum clamping voltage of the P6KE8.2C under rated surge conditions?
The P6KE8.2C has a maximum clamping voltage (VC) of 12.5V when subjected to a 200A peak pulse current with a 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry will not experience more than 12.5V during such an event - critical for protecting 5V and 3.3V logic interfaces. The P6KE8.2C achieves this while maintaining low dynamic impedance and fast response.
Is the P6KE8.2C suitable for automotive applications?
Yes - the P6KE8.2C is offered in an AEC-Q101-qualified version (P6KE8.2CH) that passes rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD immunity. Its -55°C to +175°C junction temperature range, UL 94V-0 molding, and DO-204AC mechanical robustness make the P6KE8.2C appropriate for under-hood and cabin modules. Always specify the "H" suffix for automotive-grade compliance.
How does the P6KE8.2C differ from unidirectional TVS diodes like P6KE8.2A?
The P6KE8.2C is bidirectional, meaning it clamps transients of either polarity symmetrically - ideal for AC-coupled or floating lines such as RS-485 or audio signals. In contrast, P6KE8.2A is unidirectional with a defined cathode band and only clamps negative transients relative to its anode. The P6KE8.2C eliminates need for polarity-aware layout and supports dual-polarity surge suppression without additional components.
What is the standoff voltage (VWM) of the P6KE8.2C, and why does it matter?
The P6KE8.2C has a maximum working peak reverse voltage (VWM) of 6.63V - the highest continuous DC or RMS voltage it can block without significant leakage. This parameter ensures reliable operation in 5V systems where normal operating voltage must remain safely below the clamping threshold. Exceeding VWM risks increased leakage current and premature aging; the P6KE8.2C's 6.63V rating provides ~33% margin above standard 5V rails.
Can the P6KE8.2C be used in surface-mount designs?
No - the P6KE8.2C uses the DO-204AC (DO-15) axial leaded package, which is through-hole only. For surface-mount alternatives, consider the SMBJ8.0CA (SMB package) or SMCJ8.0C (SMC package), both offering similar voltage ratings but differing in surge capacity and thermal dissipation. The P6KE8.2C's axial form factor provides superior mechanical stability and thermal mass for high-energy surge events in ruggedized applications.
