Product details
Overview
P6KE250CA-E3/54 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 250 V standoff voltage (VWM), 344 V maximum clamping voltage (VC) at 1.7 A peak pulse current, and 600 W peak pulse power dissipation with a 10/1000 μs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and lightning surges in industrial and automotive systems.
For engineers reviewing the P6KE250CA-E3/54 datasheet, P6KE250CA-E3/54 pinout, P6KE250CA-E3/54 application, or P6KE250CA-E3/54 equivalent, key selection criteria include bidirectional clamping symmetry, DO-15 package thermal resistance (RθJL = 20 °C/W), AEC-Q101 qualification status, and verified clamping performance under repetitive 0.01% duty cycle surges.
Technical Context
This device operates as a voltage-clamped shunt protector: during transient events exceeding its breakdown voltage (VBR = 237–263 V), it rapidly switches from high-impedance to low-impedance state to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns).
Designed for unclamped operation in bidirectional configurations, P6KE250CA-E3/54 exhibits symmetrical electrical characteristics in both polarities - enabling use on AC lines or differential signal pairs without polarity concerns. Its DO-15 package supports lead temperature up to 75 °C with 5.0 W steady-state power dissipation and withstands solder dip at 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 214 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR min/max | 237 V / 263 V at 1.0 mA - Confirmed breakdown threshold range; ensures predictable turn-on across production lots. |
| VC @ IPPM | 344 V at 1.7 A - Maximum clamped voltage during 10/1000 μs surge; directly limits stress on protected ICs. |
| PPPM | 600 W - Peak pulse power handling capability; validates survivability against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | <1.0 μA - Reverse leakage current at rated standoff voltage; critical for low-power sensor and battery-backed circuits. |
| TJ max | +175 °C - Maximum junction temperature; enables reliable operation in under-hood automotive or enclosed industrial enclosures. |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking - bidirectional construction eliminates cathode/anode identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked) | Transient current path | Both terminals function identically; surge current flows symmetrically regardless of polarity - no PCB layout orientation constraint. |
| Lead 1 / Lead 2 | Thermal conduction path | Leads serve as primary heat sink interface; RθJL = 20 °C/W enables direct PCB copper pour thermal coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance (±5%) and low leakage (<1 μA) over 1000-hour HTOL testing. |
| 600 W 10/1000 μs pulse rating | Validates compliance with IEC 61000-4-5 surge immunity requirements for industrial control and telecom infrastructure. |
| AEC-Q101 qualified (HE3 variant) | P6KE250CA-E3/54 is commercial-grade; HE3 suffix denotes automotive qualification - critical for functional safety validation in ADAS sensors. |
| UL 94 V-0 molding compound | Prevents flame propagation in enclosed enclosures; required for UL 60950-1 and UL 62368-1 certified end equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA | DO-214AA package; lower RθJA (50 °C/W vs. 75 °C/W); same VWM/VC specs but 600 W rating at 10/1000 μs. | Surface-mount footprint reduces board space; better suited for automated assembly and higher-density layouts. | Select SMBJ250CA when reflow compatibility and smaller PCB area are prioritized over through-hole mechanical robustness. |
| 1.5KE250CA | Same DO-15 package; higher 1500 W peak power rating; VC = 354 V at 4.3 A - less precise clamping for same VWM. | Used where higher single-event surge margin is needed (e.g., outdoor telecom cabinets), accepting wider clamping spread. | Choose 1.5KE250CA only if system-level testing confirms 354 V clamping is acceptable for protected IC absolute maximum ratings. |
Compared with SMBJ250CA and 1.5KE250CA, P6KE250CA-E3/54 offers optimal balance of axial-leaded mechanical reliability, cost-effective commercial-grade qualification, and tightly controlled 344 V clamping - making it ideal for mid-tier industrial controls where DO-15 mounting strength and thermal derating predictability are design-critical.

FAQ
What is the breakdown voltage range for P6KE250CA-E3/54?
The breakdown voltage (VBR) of P6KE250CA-E3/54 is specified as 237 V minimum to 263 V maximum at 1.0 mA test current. This range ensures consistent clamping behavior across manufacturing lots and temperature extremes, and is measured under bidirectional conditions per the device's CA suffix designation. The P6KE250CA-E3/54 maintains this specification at TA = 25 °C with a temperature coefficient of 0.110 %/°C.
Is P6KE250CA-E3/54 AEC-Q101 qualified?
No, P6KE250CA-E3/54 is the commercial-grade version with E3 suffix (RoHS-compliant, JESD 201 Class 1A whisker tested). The AEC-Q101 qualified variant is P6KE250CAHE3/54 (HE3 suffix). While both share identical electrical specs and DO-15 packaging, only the HE3 version has undergone full automotive stress testing per AEC-Q101 Rev H - essential for under-hood or safety-critical ECUs.
What is the maximum clamping voltage of P6KE250CA-E3/54 and at what current?
The maximum clamping voltage (VC) of P6KE250CA-E3/54 is 344 V, measured at a peak pulse current (IPPM) of 1.7 A using the standard 10/1000 μs waveform. This value represents the worst-case voltage imposed on protected circuitry during surge events and is guaranteed across the full operating temperature range (–55 °C to +175 °C).
Can P6KE250CA-E3/54 be used in AC line protection?
Yes, P6KE250CA-E3/54 is explicitly designed for bidirectional applications and is suitable for AC line protection where symmetrical clamping is required - such as across transformer secondaries, AC sensor inputs, or differential communication lines. Its CA suffix confirms bidirectional functionality, and electrical characteristics (VBR, VC, ID) apply identically in both polarities without derating.
What is the thermal resistance from junction to lead for P6KE250CA-E3/54?
The typical thermal resistance from junction to lead (RθJL) for P6KE250CA-E3/54 is 20 °C/W. This parameter is critical for calculating junction temperature rise under sustained power dissipation and informs PCB copper pour design - for example, a 1.0 W steady-state loss results in ~20 °C rise above lead temperature. RθJL is measured with 0.375" (9.5 mm) lead length per JEDEC standards.
