Product details
Overview
P6KE300C from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 300V nominal breakdown voltage (270–330V), 600W peak pulse power rating at 10/1000μs, clamping voltage of 430V at 1.4A peak surge current, and low dynamic impedance for effective overvoltage clamping in automotive lighting control modules.
For engineers reviewing the P6KE300C datasheet, P6KE300C pinout, P6KE300C application, or P6KE300C equivalent, key selection considerations include its DO-204AC (DO-15) axial package, bidirectional polarity marking, AEC-Q101 qualification (H-suffix variant), and suitability for EFT/ESD immunity in industrial I/O interfaces and automotive body electronics.
Technical Context
The P6KE300C operates as a silicon avalanche diode with symmetrical bidirectional clamping behavior-no anode/cathode distinction-enabling protection against both positive and negative transients without polarity constraints. Its junction capacitance is not specified in the provided documentation, and it exhibits a temperature coefficient of VBR at 0.110%/°C.
It complies with ANSI/IEEE C62.35 for transient suppression standards and delivers fast response (<5.0ns for bidirectional mode), low leakage (<1μA at 243V standoff), and robust thermal performance up to TJ = +175°C. The device is rated for non-repetitive 10/1000μs surges only and requires derating above TA = 25°C per published curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (PPK) | 600W at 10/1000μs waveform - defines maximum single-event surge energy absorption capability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ300CA | Same DO-214AC (SMA) package; 300V VBR min/max identical; 600W rating; slightly higher VC = 436V @ 1.4A | Surface-mount alternative requiring PCB redesign; better thermal performance in high-density layouts | Select when automated SMT assembly and space-constrained board real estate are priorities over through-hole serviceability |
| Vishay 1.5KE300CA | Same DO-201AD (DO-27) axial package; identical VBR (270–330V), VC = 430V, but higher PPK = 1500W and IPP = 3.5A | Higher surge margin suitable for harsher environments like railway signaling or heavy-industrial motor drives | Choose when legacy DO-201AD footprint compatibility is required and system-level surge threat exceeds 600W expectations |
Compared with P6KE300C, SMAJ300CA offers SMT convenience at the cost of manual reworkability, while 1.5KE300CA provides greater surge headroom in the same axial form factor-making it preferable for mission-critical infrastructure where overdesign margin is justified.

FAQ
What is the polarity configuration of P6KE300C?
P6KE300C is a bidirectional TVS diode with symmetrical construction-neither terminal is designated anode or cathode. It clamps transients of either polarity equally and carries no polarity marking on the DO-15 package. This makes P6KE300C ideal for protecting AC-coupled signals or floating DC buses where polarity reversal may occur.
Is P6KE300C AEC-Q101 qualified?
The base P6KE300C is not AEC-Q101 qualified; however, the P6KE300CH variant (with "H" suffix) is fully AEC-Q101 certified for automotive applications. The "H" denotes qualification per stress test conditions including temperature cycling, humidity bias HAST, and mechanical shock-critical for under-hood deployment. Always verify the full part number suffix when specifying for automotive use.
What is the maximum clamping voltage of P6KE300C under surge conditions?
The maximum clamping voltage (VC) of P6KE300C is 430V at a peak pulse current (IPP) of 1.4A with a 10/1000μs waveform. This value is guaranteed across the full operating temperature range and represents the highest voltage that will appear across the protected circuit during a worst-case surge event within the device's rated capability.
Can P6KE300C be used in place of P6KE300A?
No-P6KE300C and P6KE300A are electrically distinct variants: P6KE300C is bidirectional, while P6KE300A is unidirectional with cathode marking. Substituting one for the other risks failure to clamp reverse-polarity transients or unintended forward conduction. Always match the suffix: "C" for bidirectional, "A" for unidirectional, and "CH"/"AH" for AEC-Q101 versions.
What is the standoff voltage rating for P6KE300C?
The standoff voltage (VWM) for P6KE300C is 243V - the maximum DC or RMS voltage that can be continuously applied without exceeding 1μA leakage current. This ensures minimal power loss and signal interference during normal operation while maintaining sufficient margin below the 270V minimum breakdown threshold.
