Taiwan Semiconductor Corporation P6KE200

Overview

P6KE200 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 200V nominal breakdown voltage (VBR = 180–220V), 162V maximum standoff voltage (VWM), clamps to ≤287V at 2.1A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input protection.

For engineers reviewing the P6KE200 datasheet, P6KE200 pinout, P6KE200 application, or P6KE200 equivalent, this device is selected for high-energy ESD and lightning-induced surge suppression where fast response (<1.0ps), low dynamic impedance, and AEC-Q101 qualification (in H-suffix variants) are critical - especially in automotive body electronics, industrial PLC I/O modules, and AC/DC adapter front-end circuits.

Technical Context

The P6KE200 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its VBR range (180–220V at 1mA test current). Its clamping action limits transient energy to ≤287V at 2.1A (10/1000μs waveform), delivering 600W peak pulse power capability with junction temperature rated from –55°C to +175°C.

It exhibits <1μA maximum reverse leakage at 162V (VWM), a 0.108%/°C temperature coefficient of VBR, and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards. The DO-204AC package supports lead-free soldering per J-STD-002 and enables through-hole mounting on PCBs with 5×5 mm copper pads per terminal.

FAQ

What is the maximum clamping voltage of the P6KE200 under standard surge conditions?

The P6KE200 clamps to a maximum of 287 V when subjected to a 10/1000 μs surge waveform at 2.1 A peak current (IPPM), as specified in the Electrical Specifications table. This value represents the upper limit of voltage seen by downstream circuitry during transient events and is measured at TA = 25°C with proper PCB thermal relief per datasheet conditions.

Is the P6KE200 unidirectional or bidirectional, and how is polarity identified?

The P6KE200 is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage. Polarity is marked by a cathode band on the DO-204AC (DO-15) package - the banded end connects to the protected line, while the unmarked end connects to ground. Bidirectional variants use "CA" suffixes (e.g., P6KE200CA), which the P6KE200 does not have.

Does the P6KE200 meet automotive qualification standards?

The base P6KE200 is not AEC-Q101 qualified; however, the P6KE200H variant - indicated by the "H" suffix in the ordering code - is explicitly AEC-Q101 qualified per the Ordering Information section. Engineers requiring automotive-grade assurance must specify P6KE200H, which shares identical electrical parameters but undergoes additional stress testing for under-hood reliability.

What is the standoff voltage (VWM) rating for the P6KE200, and why does it matter?

The P6KE200 has a maximum standoff voltage (VWM) of 162 V, meaning it remains in high-impedance state up to this DC or RMS voltage level. This ensures no significant leakage current flows during normal operation, preserving system efficiency and preventing false triggering - critical for protecting 150–200V-rated power stages without unnecessary conduction losses.

Can the P6KE200 be used in parallel for higher surge current handling?

No - the P6KE200 is not designed for parallel operation due to mismatch in VBR tolerances (180–220 V) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power device (e.g., 1500W TVS) or implement staged protection with upstream MOVs and downstream low-capacitance TVS arrays.
