Product details
Overview
P6KE250CH 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 250V nominal breakdown voltage (VBR min/max: 225V–275V), 202V standoff voltage (VWM), clamping voltage of 360V at 1.7A peak surge current, and operates within -55°C to +175°C junction temperature range. It is AEC-Q101 qualified and housed in DO-204AC (DO-15) package for automotive-grade ESD and lightning transient suppression.
For engineers reviewing the P6KE250CH datasheet, P6KE250CH pinout, P6KE250CH application, or P6KE250CH equivalent, key selection criteria include its 360V clamping performance at 1.7A IPP, 202V working voltage margin, AEC-Q101 qualification status, DO-15 mechanical compatibility, and low leakage (<1μA @ 202V) in high-impedance sensing circuits.
Technical Context
The P6KE250CH employs a silicon avalanche diode structure optimized for fast response (<1.0ps rise time from 0V to VBR) and low dynamic impedance to limit transient overvoltage before downstream ICs are damaged. Its unidirectional configuration provides asymmetric conduction-blocking reverse voltage up to 202V while clamping positive surges above 225V.
It complies with ANSI/IEEE C62.35 for surge testing and delivers 600W non-repetitive peak pulse power under standardized 10/1000μs waveform. Thermal derating begins above 25°C ambient, with full power rated only at TA ≤25°C and linearly reduced to zero at 175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 202 V - Maximum continuous reverse voltage the device blocks without significant leakage; defines safe operating DC bias margin. |
| VBR (Breakdown Voltage) | 225–275 V - Voltage range at which avalanche conduction initiates at 1 mA test current; ensures reliable triggering during transients. |
| VC @ IPPM (Clamping Voltage) | 360 V @ 1.7 A - Maximum voltage seen across the device during a 10/1000μs surge; critical for protecting 300–350V-rated components. |
| PPK (Peak Pulse Power) | 600 W - Energy-handling capability under standard 10/1000μs waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| IR @ VWM (Reverse Leakage) | <1 μA @ 202 V - Negligible loading on high-impedance circuits; avoids signal distortion or battery drain in always-on systems. |
| TJ max (Junction Temperature) | +175 °C - Enables operation in under-hood automotive environments and industrial enclosures without thermal shutdown. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress-test requirements including temperature cycling, HTRB, and ESD; supports PPAP documentation. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Dimensions conform to JEDEC DO-15 outline; leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward conduction terminal | Connected to system ground or low-side return path; conducts during forward-biased surge events (uni-directional only). |
| Cathode (banded end) | Reverse-blocking / clamping terminal | Connected to protected line (e.g., 24V rail); avalanches into conduction when line voltage exceeds VBR, shunting surge current to ground. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress-test protocol; supports functional safety-aware designs. |
| 600W 10/1000μs surge rating | Withstands IEC 61000-4-5 Combination Wave (1.2/50μs voltage + 8/20μs current) up to Level 4 (4kV/2Ω) without degradation. |
| Sub-nanosecond response time | <1.0 ps rise time from 0V to VBR ensures clamping activation before most microsecond-scale transients fully develop. |
| Low clamping ratio (VC/VBR) | 360V / 225V = 1.6 - Tight voltage margin between breakdown and clamping enables robust protection of 300V-class MOSFETs and controllers. |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and UL 94V-0 flammability; suitable for consumer, industrial, and automotive PCB assemblies requiring green manufacturing. |
Applications

| LED Streetlight Driver Input | Telecom Power Feeds (48V) |
|
Use Scenario: AC/DC primary-side input of outdoor LED drivers subjected to lightning-induced surges on long feeder lines. IC Role / Device Role / Timing Role: First-line transient suppressor before bridge rectifier and bulk capacitor. Use Value: Clamps induced common-mode surges up to 6kV (IEC 61000-4-5) to safe levels, extending electrolytic capacitor life and preventing rectifier failure. |
Use Scenario: 48V DC feed to remote radio units (RRUs) in cellular base stations, vulnerable to ground potential differences and nearby lightning. IC Role / Device Role / Timing Role: Secondary-level protection after gas discharge tube (GDT), providing precise low-clamp backup. Use Value: Limits residual voltage to ≤360V after GDT crowbar action, safeguarding PoE-like interface ICs and DC-DC controllers rated for 350V max input. |
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 SMAJ250A | Same 250V nominal, 360V VC @ 1.7A, but rated 400W (not 600W); DO-214AC (SMA) surface-mount package. | Requires PCB re-layout; lacks AEC-Q101 qualification; lower surge rating limits use in automotive load dump. | Select if space-constrained SMT design prioritizes footprint over automotive qualification and 600W headroom. |
| ON Semiconductor 1.5KE250A | Same 250V/360V specs and DO-15 package, but not AEC-Q101 qualified; 1.5kW rating applies only to 1.0/1000μs waveform (not 10/1000μs). | Not validated for automotive temperature cycling or humidity testing; higher leakage (~5μA @ VWM) may affect precision sensor rails. | Acceptable for cost-sensitive industrial power supplies where AEC-Q101 is not mandated and 1.0/1000μs surge profile suffices. |
Compared with SMAJ250A and 1.5KE250A, the P6KE250CH uniquely combines AEC-Q101 qualification, 600W 10/1000μs rating, and DO-15 through-hole compatibility-making it the only option qualified for under-hood automotive surge protection without layout change or derating.

FAQ
What is the clamping voltage of the P6KE250CH under maximum surge conditions?
The P6KE250CH has a maximum clamping voltage (VC) of 360 V when subjected to its rated peak pulse current (IPPM) of 1.7 A under the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 360 V during transient events, making the P6KE250CH suitable for protecting 300–350 V-rated devices in automotive and industrial applications.
Is the P6KE250CH suitable for bidirectional surge protection?
No, the P6KE250CH is a unidirectional TVS diode, indicated by the "H" suffix (AEC-Q101 qualified) and absence of "CA" or "C" designation. It blocks reverse voltage up to 202 V and clamps only positive transients above ~225 V. For bidirectional protection, select P6KE250CH's counterpart P6KE250A (if AEC-Q101 not required) or P6KE250CH's family-matched bidirectional variant P6KE250C (not AEC-Q101 qualified per datasheet note).
What does the "H" suffix in P6KE250CH signify?
The "H" suffix in P6KE250CH denotes AEC-Q101 qualification per the manufacturer's ordering code table. It confirms that this specific variant has undergone rigorous stress testing-including temperature cycling, highly accelerated life testing (HALT), and ESD validation-for use in automotive electronic systems. The base P6KE250C (without "H") is functionally identical but not AEC-Q101 certified.
Can the P6KE250CH be used in place of the P6KE250A in an existing design?
Yes, the P6KE250CH is pin-compatible and electrically equivalent to P6KE250A in terms of VWM (202 V), VBR (225–275 V), VC (360 V), and package (DO-15). The only difference is AEC-Q101 qualification: P6KE250CH adds automotive reliability validation without altering electrical behavior or footprint. No PCB or schematic changes are needed when upgrading from P6KE250A to P6KE250CH.
What is the maximum junction temperature rating for the P6KE250CH?
The P6KE250CH has a maximum junction temperature (TJ max) of +175 °C, enabling reliable operation in high-temperature environments such as engine compartments, industrial motor drives, and enclosed LED luminaires. This rating is maintained under specified power derating curves and supports continuous operation at elevated ambient temperatures when mounted per JEDEC 5 x 5 mm copper pad guidelines.
