Product details
Overview
P6KE30AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 30V nominal breakdown voltage (VBR min/max: 28.5V–31.5V), 25.6V stand-off voltage (VWM), clamps to ≤41.4V at 15A peak surge current, and delivers sub-nanosecond response (<1.0ps) with <1μA leakage above 10V. It is AEC-Q101 qualified and housed in a DO-204AC (DO-15) package for automotive body electronics and industrial control inputs.
For engineers reviewing the P6KE30AH datasheet, P6KE30AH pinout, P6KE30AH application, or P6KE30AH equivalent, key selection criteria include its AEC-Q101 qualification status, 41.4V clamping voltage at 15A, 25.6V working voltage margin, and DO-15 mechanical compatibility with legacy PCB footprints - critical for ESD/inductive-spike protection in 24V automotive subsystems and industrial I/O modules.
Technical Context
The P6KE30AH operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to shunt transient energy away from downstream circuitry. Its low dynamic impedance ensures stable clamping under fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), while its 175°C maximum junction temperature supports operation in under-hood environments.
Designed for single-pulse 10/1000μs waveform compliance, it sustains 600W non-repetitive peak power and handles up to 100A forward surge current (8.3ms half-sine). Its temperature coefficient of VBR is +0.097%/°C, enabling predictable voltage drift across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min–max) | 28.5V–31.5V at 1mA test current - defines reliable conduction onset window for overvoltage detection |
| VWM | 25.6V - maximum continuous reverse operating voltage before leakage exceeds 1μA |
| VC @ IPP | ≤41.4V at 15A peak pulse - clamping voltage limiting stress on protected ICs during transients |
| PPK | 600W at 10/1000μs - surge energy handling capacity for automotive load-dump and EFT events |
| IR @ VWM | <1μA - minimal standby power loss and negligible loading on 24V supply rails |
| Response time | <1.0ps - enables suppression of nanosecond-scale ESD events per IEC 61000-4-2 |
| Package | DO-204AC (DO-15) - industry-standard axial leaded package with 0.400g mass and UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded plastic case with cathode band marking for unidirectional polarity. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference node for reverse-biased operation | Connected to system ground or lower-potential rail; defines current path during clamping |
| Cathode | Protected line connection point | Connected to line being safeguarded (e.g., 24V supply input); carries surge current to ground during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress requirements |
| 600W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 1 (−150V/2Ω) and Pulse 2a (−100V/50Ω) without degradation |
| Clamping ratio (VC/VBR) | 1.30–1.45 - tight ratio ensures minimal overvoltage overshoot during fast transients |
| Low leakage (<1μA @ VWM) | Prevents measurable current draw on always-on 24V circuits, preserving battery life in sleep modes |
| UL 94V-0 flammability rating | Self-extinguishing encapsulation meets automotive cabin and engine bay safety standards |
Applications

Use Value: <1μA leakage preserves battery backup runtime; AEC-Q101 qualification ensures traceable process controls for regulated medical BOMs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode 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 - higher clamping voltage, lower surge current rating | Not AEC-Q101 qualified; rated for commercial/industrial use only | Select when DO-214AC footprint is preferred and AEC-Q101 is not required |
| ON Semiconductor 1.5KE30A | DO-201AD package; identical VBR/VWM/VC specs but 1.5kW peak power rating - larger thermal mass, slower response (~1ns) | Higher power dissipation capability suits repetitive surge environments (e.g., motor drives) | Select when sustained surge duty cycle exceeds single-pulse capability of P6KE30AH |
Compared with SMAJ30A and 1.5KE30A, the P6KE30AH uniquely combines AEC-Q101 qualification, DO-15 footprint compatibility, and optimized 41.4V clamping for space-constrained automotive modules where regulatory compliance and board-level interchangeability are mandatory.

FAQ
What is the AEC-Q101 qualification status of the P6KE30AH?
The P6KE30AH is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in the P6KE SERIES datasheet Version P2203. This qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per automotive stress requirements - making it suitable for under-hood and body electronics applications where reliability is mandated.
How does the clamping voltage of P6KE30AH compare to its breakdown voltage?
The P6KE30AH has a breakdown voltage range of 28.5V–31.5V at 1mA and clamps to a maximum of 41.4V at 15A peak current. This 31–45% clamping ratio reflects its low dynamic impedance design, ensuring protected circuits experience minimal overvoltage overshoot during fast transients like ESD or inductive switching spikes.
Can P6KE30AH be used in bidirectional configurations?
No - the P6KE30AH is unidirectional only, as indicated by its "H" suffix and absence of "CA" or "C" designation. Bidirectional variants (e.g., P6KE30A) exist in the same family but feature symmetrical breakdown in both polarities; using P6KE30AH in reverse-biased AC applications would result in forward conduction and failure.
What is the maximum ambient temperature for continuous operation of P6KE30AH?
The P6KE30AH supports continuous operation up to +175°C junction temperature. When mounted on 5×5 mm copper pads per JEDEC standards, its derated power dissipation allows stable performance at ambient temperatures up to +125°C - sufficient for engine control units and industrial motor drives with active thermal management.
Is the DO-204AC (DO-15) package of P6KE30AH compatible with automated assembly?
Yes - the P6KE30AH is supplied in tape-and-reel format (3,500 units/reel) with pure tin-plated leads compliant with J-STD-002 for solderability. Its DO-204AC body dimensions and lead spacing are compatible with standard axial-component pick-and-place equipment and wave/reflow soldering profiles used in high-volume manufacturing.
