Product details
Overview
P6KE30A 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 30V nominal breakdown voltage (28.5–31.5V), 25.6V stand-off voltage, 41.4V maximum clamping voltage at 15A peak surge current, and low dynamic impedance for fast response to ESD and lightning-induced transients in automotive and industrial control modules.
For engineers reviewing the P6KE30A datasheet, P6KE30A pinout, P6KE30A application, or P6KE30A equivalent, key selection criteria include clamping performance under 10/1000μs surge, junction temperature derating above 25°C, unidirectional polarity marking, DO-204AC (DO-15) package compatibility with through-hole PCB layouts, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The P6KE30A operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified VBR range (28.5–31.5V at 1mA test current). Its clamping action limits transient energy by diverting surge current to ground while maintaining <41.4V across protected circuitry during a 15A 10/1000μs pulse.
It exhibits <1μA reverse leakage at 25.6V (VWM), a 0.097%/°C temperature coefficient of VBR, and thermal stability up to TJ = +175°C. The device is not bidirectional - polarity is marked on the cathode band per DO-204AC mechanical drawing, and forward surge rating (IFSM = 100A, 8.3ms half-sine) applies only in forward conduction mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 30V - defines rated suppression threshold for system-level overvoltage design margin |
| Breakdown Voltage VBR | 28.5–31.5V at 1mA - ensures reliable triggering before downstream IC damage thresholds |
| Stand-Off Voltage VWM | 25.6V - maximum continuous reverse voltage without significant leakage (<1μA) |
| Clamping Voltage VC | 41.4V at 15A IPP - limits voltage seen by protected load during worst-case 10/1000μs surge |
| Peak Pulse Power | 600W - sustains single high-energy transients common in automotive load-dump or inductive switching |
| Junction Temperature | −55°C to +175°C - supports operation in under-hood and industrial ambient environments |
| Package | DO-204AC (DO-15) - standard through-hole package with tin-plated leads, UL 94V-0 molding |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, epoxy-molded, cathode band marked on one end. 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 | Input/Line side | Connected to protected line (e.g., 24V rail); conducts forward during fault if used in series configuration |
| Cathode | Ground/Return side | Connected to system ground; avalanche conduction occurs between cathode and anode during reverse overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600W surge capability | Handles single 10/1000μs transients up to 600W without degradation - sufficient for ISO 7637-2 Pulse 5a load dump in 12V systems |
| Fast response time | Typically <1.0ps from 0V to VBR - enables protection of high-speed logic and microcontroller I/O against ESD events |
| Low dynamic impedance | Ensures minimal voltage overshoot during clamping - critical for safeguarding 3.3V/5V logic supply domains |
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics - meets stress testing for temperature cycling, HTRB, and HTGB |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive - suitable for green manufacturing and export compliance |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12V/24V battery-fed ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary shunt TVS placed at power entry point to clamp surges before LDOs and MCUs. Use Value: Limits voltage to ≤41.4V during 15A transients, preventing latch-up or gate oxide rupture in downstream regulators and microcontrollers. | Use Scenario: 4–20mA current loop or analog sensor inputs in PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional TVS connected between signal line and ground to absorb EFT bursts and cable discharge events. Use Value: Clamps induced transients below 41.4V while adding <1μA leakage at 25.6V - preserves signal integrity and ADC accuracy. |
| Lighting Driver Overvoltage Suppression | Motor Control Board Surge Protection |
Use Scenario: LED driver input stage subjected to inductive kickback from relay switching or hot-plug events. IC Role / Device Role / Timing Role: Front-end TVS on DC input rail to protect MOSFET gate drivers and current sense amplifiers.

IC Role / Device Role / Timing Role: Unidirectional TVS across VDD and GND to clamp voltage overshoot during MOSFET turn-off transitions. Use Value: Maintains clamping voltage at 41.4V even at 15A surge, preventing overvoltage shutdown or bootstrap capacitor overstress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A | Same 30V nominal, 43.5V clamping at 13.3A; SMB package (SMT), lower 600W rating derated faster above 75°C | Preferred for space-constrained PCBs requiring surface-mount assembly; lacks AEC-Q101 qualification unless explicitly marked | Select SMBJ30A when board real estate is limited and reflow compatibility is required; verify thermal pad layout for sustained power dissipation. |
| 1.5KE30A | Same DO-15 package, identical VBR/VWM/VC specs, but rated for 1500W peak power (1.5kW) - larger die, higher surge margin | Used where higher single-pulse robustness is needed (e.g., heavy-duty industrial motor controls), but with increased capacitance and cost | Choose 1.5KE30A only if system-level surge testing requires >600W headroom; otherwise P6KE30A offers optimal cost-performance balance. |
Compared with SMBJ30A and 1.5KE30A, the P6KE30A delivers AEC-Q101 qualification in a proven DO-15 through-hole package with precise 41.4V clamping - making it ideal for automotive and industrial designs where reliability, legacy footprint compatibility, and standardized surge immunity are prioritized over ultra-high-power or SMT-only assembly.

FAQ
What is the clamping voltage of the P6KE30A and how is it measured?
The P6KE30A has a maximum clamping voltage (VC) of 41.4V at 15A peak pulse current (IPP), tested using a 10/1000μs waveform per ANSI/IEEE C62.35. This value represents the upper limit of voltage imposed on protected circuitry during a standardized surge event - critical for ensuring downstream ICs remain within absolute maximum ratings. The P6KE30A maintains this clamping performance across its full operating temperature range.
Is the P6KE30A bidirectional or unidirectional?
The P6KE30A is a unidirectional TVS diode, indicated by the absence of "C" or "CA" suffix and confirmed by its single cathode band marking per DO-204AC mechanical drawing. It conducts only in reverse avalanche mode - protecting against positive transients on the cathode side - and must be oriented with cathode toward the protected circuit's ground reference. Bidirectional variants (e.g., P6KE30CA) are separate part numbers.
Does the P6KE30A meet AEC-Q101 requirements?
Yes, the P6KE30A is AEC-Q101 qualified, as documented in Taiwan Semiconductor's official P6KE series datasheet (Version P2203). This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling, and unbiased highly accelerated stress testing (uHAST), confirming suitability for automotive powertrain and chassis applications.
What is the maximum steady-state power dissipation for the P6KE30A?
The P6KE30A has a steady-state power dissipation (PD) of 5W at TA = 75°C with 0.375" (9.5mm) lead lengths mounted on 5×5 mm copper pads per terminal. This rating reflects continuous DC power handling - distinct from its 600W peak pulse rating - and must be thermally managed via PCB copper area and ambient conditions to avoid exceeding TJ = +175°C.
How does the P6KE30A compare to the P6KE30 (non-A) variant?
The P6KE30A offers tighter breakdown voltage tolerance (28.5–31.5V) versus P6KE30 (27.0–33.0V), lower clamping voltage (41.4V vs. 43.5V at rated IPP), and improved temperature coefficient consistency (0.097%/°C). These enhancements provide more predictable protection margins in precision power rail designs - especially where VBR spread could impact system-level surge margin calculations. Both share DO-204AC packaging and AEC-Q101 qualification.
