Product details
Overview
P6KE300H from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 300V nominal standoff voltage (VWM = 243V), 300V–330V breakdown range (VBR), 430V maximum clamping voltage at 1.4A peak surge current, and DO-204AC (DO-15) axial package - deployed in automotive power supply input stages to absorb load dump and ISO 7637-2 pulse 5a transients.
For engineers reviewing the P6KE300H datasheet, P6KE300H pinout, P6KE300H application, or P6KE300H equivalent, key selection criteria include clamping voltage margin vs. protected IC VMAX, junction temperature derating above 25°C, AEC-Q101 qualification status, and compatibility with 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE300H operates as a silicon avalanche diode with unidirectional polarity and single-die construction. Its low dynamic impedance enables rapid voltage clamping during fast-rising transients (<1.0 ps response from 0 V to VBR), while its 175°C maximum junction temperature supports under-hood automotive environments.
It complies with AEC-Q101 stress testing for automotive reliability and meets UL 94V-0 flammability requirements in its DO-204AC molded case. The device is rated for non-repetitive 600W peak pulse power at 10/1000μs, with thermal derating linearly applied above 25°C ambient per Fig.2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 243 V - Maximum continuous reverse voltage before leakage exceeds 1 μA; defines safe operating DC bias level. |
| VBR (Breakdown Voltage) | 270–330 V at 1 mA test current - Avalanche conduction onset range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM (Clamping Voltage) | 430 V at 1.4 A peak pulse current - Maximum voltage seen by protected circuit during 10/1000μs surge; critical for IC survivability. |
| PPK (Peak Pulse Power) | 600 W - Surge energy absorption capacity at 10/1000μs waveform; determines immunity to ISO 7637-2 Pulse 5a. |
| TJ MAX | 175 °C - Maximum allowable junction temperature; enables placement near heat sources in engine control units. |
| IR @ VWM | <1 μA - Reverse leakage at rated standoff voltage; minimizes standby power loss in always-on systems. |
| Package | DO-204AC (DO-15) - Axial-leaded through-hole package with tin-plated leads; compatible with standard wave-soldering processes. |
Pinout & Package
DO-204AC (DO-15) axial package with cathode band marking for unidirectional polarity. Leads are pure tin-plated and solderable per J-STD-002. Weight ≈ 0.400 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return; completes clamping path during positive transients on cathode side. |
| Cathode | Protected line input | Connected to line under protection (e.g., battery rail); conducts avalanche current to ground when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for powertrain and body control modules. |
| 600W 10/1000μs surge rating | Withstands ISO 7637-2 Pulse 5a (load dump) up to 600W without degradation - eliminates need for external series impedance in many 12V/24V systems. |
| 430V clamping at 1.4A | Provides ≥17% margin below typical 500V-rated automotive microcontrollers - ensures robust protection without over-clamping. |
| <1.0 ps response time | Enables suppression of sub-nanosecond EFT bursts (IEC 61000-4-4) before sensitive logic is disturbed. |
| UL 94V-0 molding compound | Self-extinguishing encapsulation prevents flame propagation in enclosed fuse boxes or junction blocks. |

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 SMAJ300A | Same DO-214AC (SMA) package; 300V VWM, 430V VC @ 1.4A; AEC-Q101 qualified; 400W rating (vs. 600W). | Lower peak power rating limits use in high-energy load dump scenarios; better suited for space-constrained PCBs. | Select when board layout favors surface-mount and surge energy is limited to ≤400W. |
| ON Semiconductor 1.5KE300A | DO-201AD package; identical 300V VWM / 430V VC specs; 1500W rating; not AEC-Q101 qualified. | Higher surge capacity supports industrial motor drives but lacks automotive qualification evidence. | Select for cost-sensitive industrial power supplies where AEC-Q101 is not mandated. |
Compared with P6KE300H, SMAJ300A trades 200W peak power for SMT footprint and thermal performance, while 1.5KE300A offers higher surge margin but no automotive qualification - making P6KE300H optimal for AEC-compliant 12V/24V systems requiring proven 600W clamping.

FAQ
What is the AEC-Q101 qualification status of P6KE300H?
P6KE300H is explicitly AEC-Q101 qualified per the manufacturer's ordering code "H" suffix and documentation in the P6KE SERIES datasheet Version P2203. This includes validation for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) per AEC-Q101 Rev D. No additional qualification testing is required for automotive use cases.
Does P6KE300H have bidirectional capability?
No, P6KE300H is a unidirectional TVS diode, indicated by its single cathode band marking and specification table entries referencing only unidirectional test conditions. Bidirectional variants in the same series carry "CA" suffixes (e.g., P6KE300CA); P6KE300H must be oriented with cathode toward the protected line.
What is the maximum clamping voltage of P6KE300H and at what current is it specified?
The maximum clamping voltage (VC) of P6KE300H is 430 V, measured at a peak pulse current (IPPM) of 1.4 A using the standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and defines the worst-case voltage imposed on protected circuitry during surge events.
Can P6KE300H be used in parallel for higher surge current handling?
No - P6KE300H is not characterized for parallel operation. Variations in VBR tolerance (270–330 V) and dynamic impedance cause uneven current sharing, risking thermal runaway in one device. For higher surge ratings, select a single higher-power TVS (e.g., 1.5KE300A) or verify matched-bin devices with derated layout per manufacturer application notes.
What is the lead finish and soldering compatibility of P6KE300H?
P6KE300H features pure tin-plated leads compliant with J-STD-002 for solderability, supporting both wave and reflow soldering processes. The DO-204AC (DO-15) package meets JEDEC moisture sensitivity level (MSL) 1 and requires no pre-bake prior to assembly. Lead spacing and diameter align with IPC-7351B generic axial footprint standards.
