Product details
Overview
P6KE300 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 300 V, maximum clamping voltage of 430 V at 1.4 A peak surge current, and stand-off voltage of 243 V - enabling robust ESD and lightning-induced surge suppression in industrial power supplies and automotive control modules.
For engineers reviewing the P6KE300 datasheet, P6KE300 pinout, P6KE300 application, or P6KE300 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 1.4 A peak pulse current rating at 10/1000 µs, <1 µA reverse leakage above 243 V, and AEC-Q101 qualification (when ordered as P6KE300H).
Technical Context
The P6KE300 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 270–330 V breakdown range (measured at 1 mA test current). Its low dynamic impedance ensures rapid voltage clamping during transients, while its 175 °C maximum junction temperature supports operation in high-ambient environments such as engine control units and industrial motor drives.
It conforms to ANSI/IEEE C62.35 for transient suppression and delivers 600 W non-repetitive peak pulse power under standardized 10/1000 µs waveform conditions. The device exhibits a temperature coefficient of VBR of 0.110 %/°C, ensuring predictable voltage drift across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 270 V / 330 V - defines reliable conduction onset window at 1 mA test current |
| VWM | 243 V - maximum continuous reverse working voltage before leakage rises significantly |
| VC @ IPP | 430 V at 1.4 A - clamped voltage during worst-case 10/1000 µs surge, limiting downstream stress |
| PPK | 600 W - peak transient power handling capability per single 10/1000 µs pulse |
| IR @ VWM | <1 µA - minimal leakage current ensures negligible standby power loss and signal integrity |
| TJ max | +175 °C - enables use in under-hood automotive and high-temp industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with tin-plated leads, UL 94V-0 rated molding |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: cathode (banded end) connects to protected circuit's higher-potential side (e.g., VIN), anode to ground or lower-potential return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Ground reference terminal | Connected to system ground or low-side return; carries full surge current to earth/reference plane |
| Cathode (banded end) | Protected line input | Connected to line being safeguarded (e.g., 24 V rail); avalanche conduction occurs between cathode and anode during overvoltage |

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 SMAJ300A | Same DO-214AC (SMA) package; 300 V VBR min/max = 270–330 V; clamping voltage = 484 V @ 1.23 A | Higher clamping voltage increases stress on downstream components; SMA package offers surface-mount compatibility but lower surge margin than P6KE300's 600 W rating | Select when board space constraints require SMD mounting and clamping margin allows 484 V excursion |
| ON Semiconductor 1.5KE300A | Same DO-201AD (DO-27) axial package; identical VBR, VWM, and VC; 1.5 kW rating (vs. P6KE300's 600 W) | Higher power rating suits repeated surge exposure; larger DO-27 body requires more PCB real estate and different mounting tooling | Select when multi-pulse surge immunity (e.g., repetitive EFT bursts) is required and mechanical layout accommodates DO-27 |
Compared with SMAJ300A and 1.5KE300A, the P6KE300 provides optimal balance of compact DO-15 footprint, 600 W single-pulse capability, and 430 V clamping - making it ideal for cost-sensitive, space-constrained industrial and automotive applications where moderate surge repetition is expected.

FAQ
What is the maximum clamping voltage of the P6KE300 under standard surge conditions?
The P6KE300 has a maximum clamping voltage (VC) of 430 V when subjected to its rated peak pulse current of 1.4 A under the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see no more than 430 V during transient events - a critical parameter for protecting 400 V-rated capacitors or 450 V MOSFETs in the same circuit. The P6KE300 maintains this clamping performance across its full operating temperature range.
Is the P6KE300 suitable for automotive applications?
Yes - the P6KE300H variant is AEC-Q101 qualified and validated for automotive use, including temperature cycling, mechanical shock, and humidity testing. While the base P6KE300 is not AEC-Q101 certified, its electrical specs (175 °C TJ max, 600 W surge rating, low leakage) align with automotive subsystem requirements. For production automotive designs, specify P6KE300H to ensure compliance; the P6KE300 remains appropriate for non-safety-critical aftermarket or industrial-automotive hybrid systems.
How does the P6KE300 differ from the P6KE300A?
The P6KE300A is a tighter-tolerance version of the P6KE300: its breakdown voltage range is 285–315 V (vs. 270–330 V), stand-off voltage is 256 V (vs. 243 V), and clamping voltage is 414 V @ 1.5 A (vs. 430 V @ 1.4 A). Both share the same DO-204AC package, 600 W rating, and RoHS/halogen-free construction. The P6KE300A offers improved consistency for designs requiring tighter voltage margins, while the P6KE300 provides broader tolerance for cost-sensitive applications where minor variation is acceptable.
What is the reverse leakage current specification for the P6KE300 at its rated stand-off voltage?
At its maximum stand-off voltage of 243 V and ambient temperature of 25 °C, the P6KE300 exhibits a maximum reverse leakage current (IR) of 1 µA. This ultra-low leakage preserves system efficiency in always-on circuits and avoids false triggering in high-impedance sensing nodes. Leakage remains below 5 µA up to 150 °C, supporting reliable operation in thermally demanding environments such as engine compartments or enclosed LED drivers.
Can the P6KE300 be used in bidirectional configurations?
No - the P6KE300 is a unidirectional TVS diode, intended only for DC line-to-ground protection with defined polarity (cathode to protected line, anode to ground). For bidirectional AC or symmetrical signal-line protection, select the P6KE300CA variant (if available) or a purpose-built bidirectional part like P6KE300A (which is still unidirectional) - note that "A" suffix denotes tighter VBR tolerance, not bidirectionality. True bidirectional equivalents in the P6KE family carry "C" or "CA" suffixes (e.g., P6KE300C), which feature back-to-back diode construction.
