Product details
Overview
P6KE30H 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 = 27.0–33.0V), 24.3V stand-off voltage (VWM), clamps to ≤41.4V at 15A peak surge current, and delivers sub-nanosecond response (<1.0ps) to ESD and lightning-induced transients in automotive body electronics.
For engineers reviewing the P6KE30H datasheet, P6KE30H pinout, P6KE30H application, or P6KE30H equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-density PCB layouts, low dynamic impedance for precise clamping, and verified performance under 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE30H operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to shunt transient energy away from downstream ICs. Its junction temperature range spans −55°C to +175°C, and it maintains stable VBR with a temperature coefficient of 0.097%/°C - critical for thermal stability in under-hood automotive environments.
It is rated for 600W non-repetitive peak pulse power (10/1000μs), supports 100A forward surge current (8.3ms half-sine), and exhibits <1μA reverse leakage above 10V - enabling low-power standby integrity in always-on vehicle modules such as door control units and lighting drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 24.3 V - Maximum continuous operating voltage before conduction; ensures no interference with 24V nominal systems during normal operation. |
| VBR (min/max) | 27.0 V / 33.0 V - Breakdown occurs within this range at 1mA test current; guarantees predictable turn-on across process and temperature variation. |
| VC @ IPP | 41.4 V @ 15 A - Clamping voltage during 10/1000μs surge; limits stress on protected 3.3V/5V/12V logic and power stages. |
| PPK | 600 W - Peak pulse power handling capacity; meets ISO 7637-2 Pulse 1 & 2a requirements for 12V automotive networks. |
| IR @ VWM | <1 μA - Reverse leakage at stand-off voltage; preserves battery drain budgets in always-on ECUs. |
| TJ max | +175 °C - Maximum junction temperature; supports placement near heat sources like power MOSFETs or LED drivers. |
| Package | DO-204AC (DO-15) - Industry-standard axial leaded package with tin-plated leads; compatible with wave and selective soldering processes. |
Pinout & Package
DO-204AC (DO-15) package: axial-leaded, molded epoxy case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD201 Class 2 whisker resistance. Polarity is unidirectional; cathode band denotes the terminal connected to the protected circuit's ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side (line-side) | Connected to the unprotected line (e.g., battery feed or signal input); conducts surge current toward cathode during overvoltage events. |
| Cathode | Ground-reference side | Connected to system ground or low-impedance return path; establishes clamping reference and defines unidirectional conduction direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock - required for front-end power protection in ADAS and body control modules. |
| 600W 10/1000μs surge rating | Withstands repetitive ISO 7637-2 transients without degradation - eliminates need for external series impedance in many 12V/24V supply rail designs. |
| Clamping voltage ≤41.4V | Ensures downstream 36V-rated CAN transceivers and microcontrollers remain within absolute maximum ratings during load dump events. |
| Response time <1.0ps | Activates faster than typical ESD pulses (IEC 61000-4-2), preventing latch-up or gate oxide damage in sensitive CMOS inputs. |
| UL 94V-0 molding compound | Flame-retardant encapsulation meets automotive interior material safety standards and prevents fire propagation in wiring harnesses. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ30A | Same DO-214AC (SMA) package; lower PPK (400W); VBR tighter (28.5–31.5V); higher IR (5μA @ VWM). | Not AEC-Q101 qualified; suitable for industrial but not automotive front-end use. | Select if footprint allows SMA package and AEC-Q101 is not required; verify thermal derating at 75°C ambient. |
| ON Semiconductor 1.5KE30A | Higher PPK (1500W); larger DO-201AD package; same VBR range; slower response (>1ns); RoHS-compliant but not AEC-Q101. | Better for high-energy lightning surges; unsuitable for space-constrained automotive PCBs due to 5.3mm lead spacing. | Choose only when surge energy exceeds 600W and board layout accommodates larger package; avoid for AEC-Q101–mandated designs. |
Compared with SMAJ30A and 1.5KE30A, the P6KE30H uniquely combines AEC-Q101 qualification, DO-15 form factor, and 600W capability - making it the only drop-in solution for automotive 12V rail protection where qualification, size, and energy rating are jointly constrained.

FAQ
What is the AEC-Q101 qualification status of P6KE30H?
The P6KE30H is explicitly AEC-Q101 qualified per the manufacturer's ordering code suffix "H", confirmed in TSC's P2203 datasheet revision. This includes full stress testing for temperature cycling, high-temperature reverse bias, and mechanical shock - making P6KE30H suitable for automotive front-end power protection where qualification is mandatory.
Does P6KE30H have bidirectional capability?
No, P6KE30H is a unidirectional TVS diode. Its cathode band marking and electrical specifications (e.g., VBR tested with 1mA DC current, no bidirectional VBR listing) confirm single-polarity operation. For bidirectional protection, TSC offers the P6KE30CA variant - which is functionally distinct and not interchangeable with P6KE30H.
What is the maximum clamping voltage of P6KE30H at rated surge current?
The maximum clamping voltage VC of P6KE30H is 41.4 V at 15 A peak pulse current (IPP), measured under the standard 10/1000μs waveform. This value is guaranteed across temperature and process variation and defines the upper voltage limit imposed on protected circuitry during surge events.
Can P6KE30H be used in 24V systems?
Yes, P6KE30H is appropriate for 24V nominal systems. Its 24.3V stand-off voltage (VWM) provides sufficient margin above 24V rail tolerances (±10%), while its 41.4V clamping voltage remains below the absolute maximum ratings of most 45V-rated power management ICs and microcontrollers used in such applications.
What is the thermal derating behavior of P6KE30H above 25°C ambient?
P6KE30H follows a linear derating curve per Figure 2 in the datasheet: peak pulse power decreases from 600W at 25°C to zero at 175°C junction temperature. At 75°C ambient (with specified PCB pad layout), steady-state power dissipation is limited to 5W - critical for thermal design when combining multiple TVS devices on dense automotive PCBs.
