P6KE Series TVS Diodes and Assortment Kits
Compare P6KE-series axial transient-voltage-suppression (TVS) diode choices for protecting compatible power and signal lines against specified transients. The current listings include individual selected grades in 10-, 20-, 50- and 100-piece packs, plus separately listed multi-value assortments of 200 or 210 pieces. Both A and CA suffixes appear. Check whether a product is a true assortment or one selected grade: a long list of model numbers in a title does not necessarily mean they all ship together.
Understand the three buying formats
- Single-grade packs: many listings have a “Color” option that actually selects one electrical model, such as P6KE15A, P6KE15CA, P6KE200A or P6KE400CA. The pack size depends on the listing and sometimes on the option itself. A title saying “17 values” or “kit” can still offer only one 50-piece grade per selected option.
- Multi-value assortments: several fixed 200-piece listings advertise 20 values at 10 pieces each. Two-option 200-piece kits distinguish P6KE--A from P6KE--CA, with their product description enumerating 20 selected grade numbers from 6.8 to 440 at 10 pieces each. A separate 210-piece, 21-value listing also offers A or CA kit choices. Verify the actual model list and direction for the selected kit; do not treat A and CA as included together.
- Mixed or conflicting listings: one product in this collection is titled 1.5KE33A, a different TVS family, despite mentioning P6KE; it is not a P6KE33A substitute by name. Some imported descriptions call P6KE parts Schottky diodes, rectifiers, LEDs or 1,500 W devices, while other P6KE listings claim 600 W. These generic or conflicting labels do not establish a component's function, package or waveform-specific rating. Confirm the selected manufacturer's datasheet.
Choose a grade for the actual line
- Start with the maximum normal operating voltage and any negative swing. In common P6KE naming, A designates unidirectional and CA bidirectional behavior, but confirm the selected full model and polarity markings on its datasheet. Do not infer direction from a shared A/CA product title.
- Compare reverse standoff voltage (VRWM), breakdown voltage (VBR) and clamping voltage (VC) at a specified pulse current against the protected device's limits. A grade number such as 15 or 200 is not automatically the clamp voltage or the highest safe normal line voltage.
- Check peak pulse power and current at the manufacturer's specified waveform, plus temperature derating, leakage and repetitive-pulse behavior. Do not apply a seller's “600 W” or “1500 W” headline across the series without matching its test conditions.
- Confirm axial lead spacing and body dimensions from the exact drawing. Listings variously say DO-15, DO-27 or DO-201AD; those names should not be treated as proof of identical fit. Check whether the option is one model, an A/CA kit, or a fixed assortment, and verify quantity before checkout.
Frequently asked questions
Does P6KE15A equal P6KE15CA?
No. Their suffixes commonly identify different suppression directions. Match polarity and complete electrical specifications, not just the grade number.
Does every product labeled “kit” include many models?
No. Some kit-titled products sell one selected model per pack; the 200-piece and 210-piece assortments are separate listings. Inspect the selected option and included-model list.
Can I use the 1.5KE33A listing as P6KE33A?
Not without independently comparing both complete datasheets. They are different series and may differ in pulse rating, dimensions and other limits.
Is a P6KE200A listing marked “original” verified as authentic?
No. That seller wording is not independent verification of manufacturer, sourcing or ratings; confirm markings and traceable specifications before design use.
