Product details
Overview
P6KE250CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for high-energy surge protection in automotive and industrial power rails. It features a 250V nominal standoff voltage, 225–275V breakdown range at 1mA, 202V maximum working voltage, 360V clamping voltage at 1.7A peak surge current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the P6KE250CAH datasheet, P6KE250CAH pinout, P6KE250CAH application, or P6KE250CAH equivalent, this device is selected for robust ESD and lightning-induced transient suppression where fast response (<5ns), low dynamic impedance, and stable clamping performance across temperature are critical.
Technical Context
The P6KE250CAH operates as a bidirectional avalanche diode with symmetrical clamping behavior in both polarities, enabling protection of AC-coupled or floating signal/power lines without polarity constraints. Its junction capacitance is not specified in the provided documentation, but its 10/1000μs surge rating and 175°C max junction temperature support operation in thermally demanding environments.
It complies with ANSI/IEEE C62.35 for transient suppression standards and meets UL 94V-0 flammability requirements in its DO-204AC (DO-15) package. The device exhibits a 0.110%/°C temperature coefficient of VBR, ensuring predictable voltage drift over temperature in automotive-grade designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Applications
| Automotive Power Rail Protection | Industrial AC Motor Drive Inputs |
|---|---|
Use Scenario: Protecting 24V/48V battery-fed ECUs and body control modules against load dump and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed across input rail and ground to shunt >100V spikes before they reach DC-DC converters or microcontrollers. Use Value: Clamps 200V+ transients to ≤360V within 5ns, preserving downstream ICs rated for 36V absolute max input. | Use Scenario: Safeguarding variable-frequency drive (VFD) rectifier inputs against switching surges and lightning-induced line transients. IC Role / Device Role / Timing Role: Parallel-connected TVS on AC line-to-line and line-to-ground paths to limit common-mode and differential-mode overvoltage. Use Value: Withstands 600W pulses without degradation, enabling long-term reliability in ungrounded or high-impedance industrial mains environments. |
| LED Streetlight Driver Protection | Telecom Power Feeds |
Use Scenario: Shielding constant-current LED drivers from induced surges on outdoor-rated 277V AC mains connections. IC Role / Device Role / Timing Role: Bidirectional TVS placed across primary-side bulk capacitor to clamp both positive and negative half-cycle transients. Use Value: 202V VWM allows normal operation during 277V RMS peaks (~392V), while 360V VC prevents overvoltage failure of bridge rectifiers and MOSFETs. | Use Scenario: Protecting PoE-powered equipment (e.g., IP cameras, wireless APs) connected to telecom-grade 48–57V DC feeds exposed to lightning coupling. IC Role / Device Role / Timing Role: Secondary-stage TVS on DC input side, downstream of primary surge arrestors, to handle residual fast-rising transients. Use Value: Low leakage (<1 μA at 202V) avoids loading the PoE signature detection circuitry, maintaining IEEE 802.3af/at compliance. |
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 SMAJ250CA | Same 250V nominal, 600W rating, DO-214AC package; slightly higher clamping voltage (371V @ 1.7A) | DO-214AC has smaller footprint and lower thermal mass than DO-15; less suitable for high-temperature ambient mounting | Select when board space is constrained and thermal derating can be managed via layout |
| Vishay 1.5KE250CA | Same 250V nominal, 1500W rating, DO-201AE package; significantly higher surge capacity but larger size and higher cost | Designed for higher-energy threat levels (e.g., direct lightning injection); over-specified for typical automotive load dump | Select only when system-level testing requires >600W pulse handling or legacy 1.5KE footprint compatibility is mandatory |
Compared with SMAJ250CA and 1.5KE250CA, the P6KE250CAH offers AEC-Q101 qualification and DO-15 mechanical robustness ideal for automotive harness-mounted protection, while balancing surge capability, thermal stability, and cost for mid-tier industrial applications.

FAQ
What is the clamping voltage of the P6KE250CAH and how is it measured?
The P6KE250CAH has a maximum clamping voltage (VC) of 360 V, measured at a peak pulse current (IPP) of 1.7 A using a 10/1000 μs double-exponential waveform. This value represents the upper voltage limit imposed on protected circuitry during standardized surge events, and is guaranteed across the full operating temperature range per the manufacturer's electrical specifications table.
Is the P6KE250CAH suitable for automotive applications?
Yes, the P6KE250CAH is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and lighting modules. Its −55°C to +175°C junction temperature range, robust DO-15 package, and validated performance under thermal cycling and humidity stress make it appropriate for under-hood and chassis-mounted surge protection where the P6KE250CAH is deployed.
How does the bidirectional configuration of the P6KE250CAH affect circuit design?
The P6KE250CAH's bidirectional structure eliminates polarity sensitivity, allowing placement across AC lines, differential signals, or floating grounds without orientation concerns. This simplifies layout, reduces BOM count, and avoids reverse-connection failures-especially valuable in high-volume manufacturing of industrial sensors or telecom interfaces where the P6KE250CAH serves as a universal clamping solution.
What is the maximum steady-state power dissipation of the P6KE250CAH?
The P6KE250CAH has a steady-state power dissipation (PD) rating of 5 W at TA = 75°C when mounted on 5 × 5 mm copper pads per lead. This thermal specification governs continuous power handling under DC bias or high-duty-cycle transients, and must be respected alongside the 600W non-repetitive surge rating to ensure long-term reliability of the P6KE250CAH in sustained overvoltage conditions.
Does the P6KE250CAH meet RoHS and halogen-free requirements?
Yes, the P6KE250CAH is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability standards, and its pure tin-plated leads comply with J-STD-002 solderability requirements-making the P6KE250CAH suitable for environmentally regulated industrial and automotive production programs.
