Product details
Overview
P6KE200-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a 171 V standoff voltage (VWM), 190–210 V breakdown range (VBR at 1 mA), 274 V maximum clamping voltage at 2.2 A peak pulse current, 600 W peak pulse power rating (10/1000 μs), and operates across –55 °C to +175 °C junction temperature. It is used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients in industrial power supplies.
For engineers reviewing the P6KE200-E3/54 datasheet, P6KE200-E3/54 pinout, P6KE200-E3/54 application, or P6KE200-E3/54 equivalent, this page delivers verified electrical parameters, DO-204AC (DO-15) package details, clamping behavior under surge conditions, thermal resistance data, and AEC-Q101-qualified alternatives - all critical for ESD/surge protection circuit design and BOM validation.
Technical Context
The P6KE200-E3/54 employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient overvoltages and low incremental surge resistance. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
It complies with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and ISO 7637-2 (automotive load dump) immunity requirements when applied with appropriate series impedance. The device derates linearly above 25 °C ambient, with 20 °C/W junction-to-lead thermal resistance enabling reliable operation up to 175 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ200A-E3/52 (Vishay) | Same VWM/VBR/VC, but SMB package (surface-mount), 600 W rating, lower RθJA (50 °C/W vs. 75 °C/W). | Requires PCB rework for SMT layout; better suited for space-constrained, high-density boards with automated assembly. | Select SMBJ200A-E3/52 when board real estate is limited and thermal management via copper pour is feasible. |
| P6SMB200A (Littelfuse) | Identical electrical specs (VWM = 171 V, VC = 274 V @ 2.2 A), DO-214AA package, RoHS-compliant, AEC-Q101 qualified option available. | Same axial form factor but different mechanical dimensions (DO-214AA vs. DO-204AC); requires footprint verification before drop-in replacement. | Choose P6SMB200A only after confirming mechanical fit and thermal performance match in target enclosure. |
Compared with P6KE200-E3/54, SMBJ200A-E3/52 offers superior thermal dissipation in SMT layouts but mandates PCB redesign, while P6SMB200A provides functional equivalence in a different axial package - requiring mechanical validation but enabling second-source procurement without electrical compromise.

FAQ
What is the maximum clamping voltage of the P6KE200-E3/54 under standard test conditions?
The P6KE200-E3/54 has a maximum clamping voltage (VC) of 274 V when subjected to a 10/1000 μs waveform at 2.2 A peak pulse current. This value is measured per JEDEC standards and represents the upper voltage limit imposed on protected circuitry during a defined surge event. The P6KE200-E3/54 maintains this clamping performance across its full operating temperature range (–55 °C to +175 °C), with minimal variation due to its stable glass-passivated junction.
Is the P6KE200-E3/54 suitable for automotive applications?
The P6KE200-E3/54 itself is a commercial-grade part (E3 suffix), but its qualified variant P6KE200AHE3/54 is AEC-Q101 certified for automotive use. Engineers selecting the P6KE200-E3/54 for automotive body electronics must verify whether qualification is required by their OEM; if so, the HE3 version should be specified. The P6KE200-E3/54 shares identical electrical characteristics and DO-204AC packaging with the HE3 variant, differing only in test documentation and whisker-class compliance.
How does the P6KE200-E3/54 compare to bidirectional TVS diodes like P6KE200CA?
The P6KE200-E3/54 is unidirectional and blocks forward current up to 171 V, making it ideal for DC-biased lines where reverse conduction must be prevented. In contrast, P6KE200CA is bidirectional with symmetrical clamping in both polarities - suitable for AC lines or differential signals. The P6KE200-E3/54 cannot replace P6KE200CA in AC applications, and vice versa, due to fundamental polarity differences that affect circuit topology and grounding strategy.
What is the thermal resistance and how does it impact PCB layout for the P6KE200-E3/54?
The P6KE200-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 75 °C/W. For sustained power dissipation, PCB layout must maximize copper area connected to both leads - especially the cathode - to emulate an infinite heatsink. Without adequate copper pour, the device may exceed 175 °C junction temperature during repetitive surges, triggering premature wear-out. The P6KE200-E3/54 benefits from ≥1 cm² of 2-oz copper per lead for optimal thermal performance.
Can the P6KE200-E3/54 be used in parallel for higher surge current handling?
No - the P6KE200-E3/54 is not recommended for parallel operation due to mismatch in breakdown voltage (190–210 V range), which causes uneven current sharing and potential thermal runaway. Even with matched lots, minor VBR variations lead to one device conducting >80 % of the surge current. For higher surge ratings, select a single higher-power device such as 1.5KE200A (1500 W), or implement staged protection with series impedance to balance energy distribution across multiple P6KE200-E3/54 units.
