Product details
Overview
P6KE300CH from Taiwan Semiconductor is a unidirectional 600W 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 (VBR min/max: 270–330V), 243V stand-off voltage (VWM), clamps to ≤430V at 1.4A peak surge current, and uses DO-204AC (DO-15) axial package for industrial power supply input stage protection.
For engineers reviewing the P6KE300CH datasheet, P6KE300CH pinout, P6KE300CH application, or P6KE300CH equivalent, key selection criteria include its AEC-Q101 qualification, 10/1000μs waveform surge rating, low dynamic impedance, fast sub-nanosecond response time, and compatibility with automated through-hole assembly processes.
Technical Context
The P6KE300CH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its VBR range (270–330V at 1mA test current). Its clamping action limits transient-induced overvoltage to ≤430V at 1.4A IPP, maintaining system-level ESD and EFT immunity per IEC 61000-4-2/4-4.
Thermal design relies on its 175°C maximum junction temperature and derating curve (Fig.2), while mechanical robustness is ensured by UL 94V-0 molding compound, pure tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 243 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin |
| VBR (min/max) | 270 / 330 V - Breakdown occurs within this range at 1 mA; ensures consistent triggering across production lots |
| VC @ IPP | ≤430 V at 1.4 A - Clamped voltage during 10/1000μs surge; determines protected circuit's voltage stress ceiling |
| PPK | 600 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 surge immunity |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient industrial environments |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with 0.400 g mass; compatible with wave soldering and manual repair |
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: anode (unmarked end), cathode (banded end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | DC return path / ground reference | Connected to system ground or low-side return; carries surge current back to source during clamping |
| Cathode (banded lead) | Protected line input | Connected to line under protection (e.g., +300V DC bus); avalanche conduction initiates here during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| 600W 10/1000μs surge rating | Withstands repeated 600W transients without parameter shift; meets IEC 61000-4-5 surge immunity requirements |
| Clamping voltage ≤430V | Ensures downstream components (e.g., MOSFETs, controllers) remain below absolute maximum ratings during surge events |
| Low IR <1 μA @ VWM | Minimizes standby power loss and avoids false triggering in high-impedance sensing circuits |
| Fast response <1.0 ps | Activates before most semiconductor damage mechanisms initiate; critical for protecting fast-switching power devices |
Applications
| Industrial Power Supply Input Protection | Automotive DC-DC Converter Input Stage |
|---|---|
Use Scenario: 300V DC bus in industrial SMPS exposed to lightning-induced surges and load dump transients. IC Role / Device Role: Primary overvoltage clamp placed across bulk capacitor input to limit transient energy entering regulation stage.

Use Scenario: 110V DC signaling rail in railway interlocking systems subject to EN 50121-4 conducted transients. IC Role / Device Role: Line-to-ground TVS on field-side interface to protect optocouplers and FPGA I/O banks. Use Value: Enables compliance with EN 50121-4 Level 3 immunity (2 kV EFT, 4 kV surge) without derating due to its 175°C TJ max and stable VBR tempco (0.110%/°C). |
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; lower PPK (400W); VBR 270–330V; VC = 484V @ 1.2A | Suitable for space-constrained PCBs but requires higher layout creepage for same voltage rating | Select if board area is limited and 400W surge margin suffices; verify clamping headroom vs. protected IC VDS(max) |
| ON Semiconductor 1.5KE300A | DO-201AD package; identical 600W rating and VBR range; VC = 430V @ 1.4A; RoHS/halogen-free compliant | Compatible with existing DO-201AD footprints; slightly larger thermal mass than DO-15 | Choose for drop-in replacement where DO-201AD footprint exists; confirm lead pitch and wave solder profile compatibility |
Compared with P6KE300CH, SMAJ300A offers smaller size but reduced surge capacity and higher clamping voltage, while 1.5KE300A matches performance in a different axial package-making it a direct functional alternative where mechanical fit allows.

FAQ
What is the polarity configuration of the P6KE300CH?
The P6KE300CH is a unidirectional TVS diode with clearly marked cathode band. It conducts only during reverse-biased overvoltage events-forward voltage drop is ~1.2V at rated current. This configuration makes P6KE300CH ideal for DC line protection where polarity is fixed, unlike bidirectional variants such as P6KE300CA.
Does the P6KE300CH meet automotive qualification standards?
Yes, the "H" suffix in P6KE300CH denotes full AEC-Q101 qualification per Rev D test plan, including HTGB, H3TRB, and ESD testing. It is approved for use in automotive power electronics including onboard chargers and DC-DC modules, provided layout and thermal management comply with TSC's application notes.
What is the maximum clamping voltage of the P6KE300CH under surge conditions?
The P6KE300CH clamps to a maximum of 430 V when subjected to a 10/1000μs surge waveform with peak current of 1.4 A (IPPM). This value is guaranteed across temperature and process variation, and defines the upper voltage limit imposed on protected circuitry during transient events.
How does the P6KE300CH compare to the P6KE300A variant?
The P6KE300CH differs from P6KE300A primarily in qualification: "H" indicates AEC-Q101 compliance, while "A" denotes tighter VBR tolerance (285–315V vs. 270–330V) without automotive qualification. Both share identical DO-204AC packaging, 600W rating, and thermal specs-but only P6KE300CH is approved for automotive applications.
Can the P6KE300CH be used in parallel for higher surge current handling?
No-P6KE300CH is not recommended for parallel operation due to VBR mismatch between units, which causes current imbalance and premature failure. For higher surge capability, select a single higher-rated device (e.g., 1500W TVS) or implement staged protection with MOV + TVS coordination verified per IEC 61643-32 guidelines.
