Product details
Overview
P6KE8V2A from Taiwan Semiconductor 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 nominal breakdown voltage of 8.2 V, clamps transients to ≤12.1 V at 200 A peak surge current, and maintains <1 μA leakage above 7.02 V standoff voltage - enabling robust ESD and lightning surge protection in automotive body electronics and industrial control I/O modules.
For engineers reviewing the P6KE8V2A datasheet, P6KE8V2A pinout, P6KE8V2A application, or P6KE8V2A equivalent, key selection criteria include its DO-15 package compatibility, 10/1000 μs waveform surge rating, unidirectional polarity marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE8V2A operates as a silicon avalanche diode with fast response (<1.0 ps from 0 V to VBR) and low dynamic impedance, enabling precise clamping during fast-rising transients such as EFT (IEC 61000-4-4) and ISO 7637-2 pulse 1/2a. Its unidirectional configuration provides asymmetric protection with cathode-band polarity marking and supports DC-biased circuits where reverse conduction must be blocked.
Thermal derating follows a linear curve above 25°C ambient, maintaining 600 W peak pulse power only at TA ≤ 25°C and reducing to ~300 W at 75°C. Junction temperature range spans −55°C to +175°C, and the device meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 600 W - sustains single high-energy surges per IEC 61000-4-5 without failure |
| Breakdown Voltage VBR | 7.79–8.61 V @ 10 mA - ensures reliable avalanche initiation within tight tolerance band |
| Standoff Voltage VWM | 7.02 V - maximum continuous DC or RMS voltage before significant leakage begins |
| Clamping Voltage VC | ≤12.1 V @ 200 A - limits downstream IC voltage stress during worst-case surge events |
| Leakage Current ID | <1 μA @ 7.02 V - minimizes standby power loss in battery-powered systems |
| Junction Temperature Range | −55°C to +175°C - supports operation in under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | DO-214AA package; 600 W rating; VBR = 8.89–9.82 V; VC = 12.7 V @ 42.1 A | Lower peak surge current (42.1 A vs. 200 A); surface-mount only | Select when PCB space is constrained and surge energy is lower (e.g., consumer USB ports) |
| 1.5KE8.2A | Same DO-15 package; 1500 W rating; VBR = 7.79–8.61 V; VC = 13.4 V @ 112 A | Higher power rating but higher clamping voltage and larger footprint | Choose for higher-energy surge environments where 13.4 V clamping is acceptable |
Compared with SMBJ8.0A, P6KE8V2A delivers 4.7× higher peak surge current in the same axial form factor; versus 1.5KE8.2A, it offers tighter clamping (12.1 V vs. 13.4 V) at lower energy levels, optimizing protection for cost-sensitive automotive and industrial modules.

FAQ
What is the breakdown voltage range of the P6KE8V2A?
The P6KE8V2A 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. This tight 10.6% tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in safety-critical circuits like automotive lighting control where the P6KE8V2A is commonly deployed.
Is the P6KE8V2A AEC-Q101 qualified?
No - the P6KE8V2A is not AEC-Q101 qualified. Per Taiwan Semiconductor's ordering information, AEC-Q101 qualification applies only to parts marked with the "H" suffix (e.g., P6KE8V2AH). The standard P6KE8V2A variant is intended for industrial and commercial applications where full automotive qualification is not required, though it shares identical electrical specs and DO-15 packaging.
What is the maximum clamping voltage of the P6KE8V2A under surge conditions?
The P6KE8V2A clamps to a maximum of 12.1 V at 200 A peak pulse current (IPP) using the 10/1000 μs waveform. This value is specified in the Electrical Specifications table and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events - a critical parameter for ensuring protected ICs remain within their absolute maximum voltage ratings.
Can the P6KE8V2A be used in bidirectional configurations?
No - the P6KE8V2A is a unidirectional TVS diode, indicated by its "A" suffix and cathode-band marking. Bidirectional variants in the P6KE series use "CA" suffixes (e.g., P6KE8V2CA). Using P6KE8V2A in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
What is the standoff voltage (VWM) of the P6KE8V2A?
The standoff voltage (VWM) of the P6KE8V2A is 7.02 V - the maximum DC or RMS voltage that can be continuously applied without exceeding 1 μA leakage current. This value allows safe integration into 5 V or 6 V systems where margin above operating voltage is needed, and directly informs minimum system voltage headroom requirements when selecting the P6KE8V2A for rail protection.
