Product details
Overview
P6KE30 from Taiwan Semiconductor is a unidirectional 30V transient voltage suppressor (TVS) diode in DO-204AC (DO-15) package, rated for 600W peak pulse power at 10/1000μs waveform, with breakdown voltage 27.0–33.0V at 1mA test current, clamping voltage 43.5V at 14A peak surge current, and maximum reverse leakage <1μA at 24.3V standoff voltage. It protects automotive and industrial power rails against ESD, lightning-induced surges, and inductive switching transients.
For engineers reviewing the P6KE30 datasheet, P6KE30 pinout, P6KE30 application, or P6KE30 equivalent, this page delivers verified electrical parameters, mechanical package details, real-world protection use cases, and validated alternative parts - all aligned to AEC-Q101-qualified TVS requirements for automotive-grade reliability and fast clamping response.
Technical Context
The P6KE30 operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its 27.0–33.0V breakdown range. Its low dynamic impedance and sub-nanosecond response (<1.0ps from 0V to VBR) enable rapid clamping of fast-rising transients before downstream ICs are damaged.
It sustains 600W non-repetitive surge energy per 10/1000μs waveform, with thermal derating above 25°C ambient and junction temperature limits from –55°C to +175°C. The device uses pure tin-plated leads compliant with J-STD-002 and meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 27.0V / 33.0V at 1mA - defines reliable turn-on threshold under surge conditions |
| VWM | 24.3V - maximum continuous reverse working voltage without significant leakage |
| VC @ IPP | 43.5V at 14.0A - clamped voltage seen by protected circuit during worst-case 600W surge |
| IR @ VWM | <1μA - negligible standby power loss and signal integrity impact in high-impedance circuits |
| PPK | 600W - peak surge handling capacity per standard 10/1000μs waveform, critical for automotive load-dump immunity |
| TJ max | +175°C - enables operation in under-hood automotive environments and high-power industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400g mass and UL 94V-0 molding compound |
Pinout & Package
DO-204AC (DO-15) axial-leaded 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) | Forward current path / ground reference | Connected to system ground or low-side return; carries surge current to ground during clamping |
| Cathode (banded lead) | Reverse-biased protection node | Connected to protected line (e.g., 24V rail); blocks normal operation but avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics |
| 600W surge capability | Meets ISO 7637-2 Pulse 5a (load dump) and IEC 61000-4-5 Level 4 immunity requirements |
| Clamping voltage ≤43.5V | Ensures protected 24V systems remain below 45V absolute maximum ratings of common PMICs and microcontrollers |
| Leakage <1μA at 24.3V | Prevents battery drain in always-on automotive modules and enables use on high-impedance sensor lines |
| Fast response <1.0ps | Activates before ESD events (IEC 61000-4-2) or fast transients propagate into sensitive analog front-ends |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: 24V supply line in engine control unit exposed to load-dump transients up to 60V for 400ms. IC Role / Device Role / Timing Role: Unidirectional TVS placed between 24V rail and chassis ground to clamp surges before they reach LDOs and MCU power pins. Use Value: Clamps peak voltage to 43.5V at 14A, preventing damage to 45V-rated power management ICs while maintaining AEC-Q101 compliance. |
Use Scenario: 4–20mA current-loop transmitter connected to PLC input subjected to field wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: TVS mounted across loop terminals to shunt transients away from precision op-amps and ADC inputs. Use Value: Sub-1.0ps response captures fast transients before they couple into analog signal paths; <1μA leakage avoids loop-current error. |
| LED Driver Overvoltage Clamp | DC-DC Converter Input Protection |
|
Use Scenario: Constant-current LED driver powered from 12V vehicle battery with risk of jump-start spikes up to 40V. IC Role / Device Role / Timing Role: P6KE30 placed across input capacitor to limit voltage excursion during cold-cranking or alternator regulation failure. Use Value: 24.3V standoff ensures stable operation during nominal 12V/14V operation; 43.5V clamping prevents MOSFET gate oxide breakdown in driver ICs. |
Use Scenario: 30V-input buck converter powering FPGA core voltage in industrial automation controller. IC Role / Device Role / Timing Role: TVS installed at DC input connector to absorb coupling from nearby motor drives and relay switching noise. Use Value: 600W rating handles repetitive 10/1000μs surges from adjacent 24V solenoid coils; DO-15 package allows through-hole mounting near entry point. |
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 P6KE30A | Narrower VBR range (28.5–31.5V), tighter tolerance; same DO-15 package and 600W rating | Better suited for designs requiring precise clamping threshold control around 30V nominal | Select P6KE30A when ±5% VBR tolerance is required versus ±10% of P6KE30 |
| ON Semiconductor 1.5KE30A | Same VBR (28.5–31.5V), identical 600W rating, but TO-204AE (DO-41) package with longer leads and higher thermal resistance | Requires PCB layout adjustment; less optimal for high-density automotive modules due to larger footprint | Choose only if legacy DO-41 footprint compatibility is mandatory and thermal margin permits |
Compared with P6KE30, P6KE30A offers improved VBR consistency for tighter voltage-margin designs, while 1.5KE30A provides functional equivalence in a different package - making P6KE30 the optimal balance of AEC-Q101 qualification, DO-15 space efficiency, and cost-effective surge robustness.

FAQ
What is the breakdown voltage range of the P6KE30?
The P6KE30 has a guaranteed breakdown voltage (VBR) range of 27.0V to 33.0V at 1mA test current, measured per ANSI/IEEE C62.35 standards. This range reflects manufacturing tolerance and ensures reliable activation during overvoltage events while avoiding false triggering during normal 24V system operation. The P6KE30's VBR is confirmed in Taiwan Semiconductor's official P2203 datasheet revision.
Is the P6KE30 suitable for automotive applications?
Yes, the P6KE30 is AEC-Q101 qualified (standard version) and designed for automotive environments, supporting junction temperatures from –55°C to +175°C. Its 600W surge rating meets ISO 7637-2 Pulse 5a load-dump requirements, and its DO-204AC package passes JESD201 Class 2 whisker testing. The P6KE30 is explicitly listed in TSC's AEC-Q101 documentation for engine control, lighting, and body electronics.
What is the maximum clamping voltage of the P6KE30 under surge conditions?
The P6KE30 clamps to a maximum of 43.5V at 14.0A peak pulse current (IPP), corresponding to its 600W 10/1000μs surge rating. This value is measured under standardized test conditions and ensures protected circuits - such as 45V-rated PMICs or microcontrollers - remain within safe operating voltage limits. The P6KE30's clamping performance is verified in the "Electrical Specifications" table of the P2203 datasheet.
Does the P6KE30 have bidirectional capability?
No, the P6KE30 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Bidirectional variants in the same series use the "CA" suffix (e.g., P6KE30CA). The P6KE30 features a cathode band marking and conducts only in reverse breakdown; forward conduction follows standard silicon diode behavior. This unidirectional configuration minimizes leakage and optimizes clamping speed for positive-rail protection.
What packaging options are available for the P6KE30?
The P6KE30 is supplied in DO-204AC (DO-15) package with two standard packing formats: 3,500 pieces per tape-and-reel (P6KE30) and 1,500 pieces per ammo box (P6KE30A0G). Both versions use pure tin-plated leads compliant with J-STD-002 solderability standards and meet RoHS and halogen-free requirements per IEC 61249-2-21. No surface-mount or alternate lead-form options exist for the P6KE30.
