Product details
Overview
P6KE30CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supplies and interface lines. It features a 30V nominal breakdown voltage (VBR min/max: 27.0–33.0V), 24.3V stand-off voltage (VWM), 43.5V maximum clamping voltage at 14A peak surge current, and operates across –55°C to +175°C junction temperature range.
For engineers reviewing the P6KE30CH datasheet, P6KE30CH pinout, P6KE30CH application, or P6KE30CH equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA @ 24.3V), AEC-Q101 qualification for automotive use, DO-15 package compatibility, and unidirectional polarity marking.
Technical Context
The P6KE30CH implements a silicon avalanche diode structure optimized for fast transient suppression with sub-nanosecond response (<1.0ps from 0V to VBR). Its unidirectional configuration provides asymmetric conduction-low-impedance clamping during reverse overvoltage while blocking forward current beyond rated IFSM (100A, 8.3ms half-sine).
Thermal design relies on DO-15 package dissipation limits: 5W steady-state at TA = 75°C with 9.5mm lead length, derated linearly above 25°C per Fig.2. Junction-to-ambient thermal resistance is not specified, but maximum TJ = 175°C defines absolute operating ceiling under pulsed conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24.3 V - Maximum continuous reverse voltage before significant leakage; sets system operating margin below clamping threshold |
| VBR (min/max) | 27.0 / 33.0 V - Breakdown occurs within this band at 1mA test current; ensures predictable turn-on across process variation |
| VC @ IPP | 43.5 V @ 14.0 A - Clamped voltage during 10/1000μs surge; defines worst-case stress on downstream ICs |
| PPK | 600 W - Peak pulse power handling capability; validates robustness against IEC 61000-4-5 Level 4 surges |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; critical for low-power sensor or battery-backed circuits |
| TJ max | +175 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments |
| Package | DO-204AC (DO-15) - Standard axial-leaded through-hole package; compatible with legacy PCB layouts and wave soldering |
Pinout & Package
DO-204AC (DO-15) package with axial leads: cathode indicated by band-marked end; anode is unmarked lead. Mounting requires 5×5 mm copper pads per terminal for rated PD = 5W at TA = 75°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient clamp output node | Connected to protected line; conducts avalanche current to ground during overvoltage events |
| Anode (unmarked end) | Reference/return path | Typically tied to system ground or low-impedance return; completes clamping current path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |
| 600W 10/1000μs surge rating | Withstands IEC 61000-4-5 combination wave surges up to 4kV open-circuit voltage without degradation |
| Fast response time | <1.0 ps rise to VBR ensures clamping initiates before sensitive ICs experience overstress |
| Low dynamic impedance | Enables tight VC–VBR spread (ΔV = 16.5V), minimizing voltage overshoot during fast transients |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12V battery rail in engine control units exposed to load dump (ISO 16750-2) and jump-start spikes. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converters and microcontrollers.

IC Role / Device Role / Timing Role: Unidirectional clamp referenced to ground, absorbing positive-going surges on power pins. Use Value: 24.3V VWM allows safe operation across USB PD 5–20V profiles; DO-15 footprint fits compact port layouts. |
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 SMAJ30A | Same DO-214AC (SMA) package; 30V VBR (28.5–31.5V), 43.5V VC @ 13.8A; lower PPK = 400W | Surface-mount only; unsuitable for through-hole designs or high-peak-energy requirements | Select when board space is constrained and surge energy is ≤400W; verify layout clearance for SMA footprint |
| ON Semiconductor 1.5KE30A | Same DO-201AD (DO-27) package; identical VBR/VC specs but higher PPK = 1500W; larger body size (4.5 × 6.2 mm vs DO-15's 2.7 × 5.2 mm) | Higher surge capacity suits industrial motor drives; mechanical fit requires pad redesign | Choose for systems requiring >600W immunity; confirm PCB real estate and thermal pad area accommodate DO-27 outline |
Compared with SMAJ30A and 1.5KE30A, the P6KE30CH offers AEC-Q101 qualification and DO-15 compatibility in a cost-effective through-hole form factor-ideal for automotive and industrial designs where qualification, legacy layout reuse, and 600W surge margin are prioritized over ultra-high energy or SMT density.

FAQ
What is the clamping voltage of the P6KE30CH under standard surge conditions?
The P6KE30CH has a maximum clamping voltage (VC) of 43.5 V at 14.0 A peak pulse current, measured using the 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the upper limit of voltage seen by downstream circuitry during a full-rated 600W transient event, ensuring protected ICs remain within safe operating limits.
Is the P6KE30CH suitable for automotive applications?
Yes, the P6KE30CH is AEC-Q101 qualified (indicated by the "H" suffix), having passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing. Its –55°C to +175°C operating range and DO-15 mechanical robustness make it appropriate for under-hood and powertrain-related transient suppression in vehicles.
How does the P6KE30CH differ from the P6KE30A variant?
The P6KE30CH is the AEC-Q101 qualified version of the P6KE30A. Both share identical electrical specs (VBR: 28.5–31.5 V, VWM: 25.6 V, VC: 41.4 V @ 15 A), but only the "H" suffix denotes automotive qualification. The "CH" suffix confirms compliance with AEC-Q101 test requirements, while P6KE30A lacks that validation and is intended for commercial/industrial use.
What is the maximum steady-state power dissipation for the P6KE30CH?
The P6KE30CH dissipates up to 5 W continuously at ambient temperature (TA) of 75°C when mounted on 5 × 5 mm copper pads per lead, per JEDEC standards. Power derating is linear above 25°C, reaching zero at 175°C ambient-consistent with its 175°C maximum junction temperature rating.
Does the P6KE30CH have polarity markings, and how is it installed?
Yes, the P6KE30CH uses standard DO-15 polarity marking: a cathode band identifies the banded end, which must be connected to the line being protected (e.g., 12V rail), while the unmarked anode lead connects to ground. Incorrect orientation prevents clamping action and may cause catastrophic failure during overvoltage events.
