Product details
Overview
P4KE250CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on power and signal lines. It features 250 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), and clamps to ≤344 V at 1.2 A peak pulse current - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the P4KE250CA-E3/54 datasheet, P4KE250CA-E3/54 pinout, P4KE250CA-E3/54 application, or P4KE250CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-41 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This TVS diode uses a glass-passivated silicon junction to achieve fast response (<1 ns) and low incremental surge resistance. Its bidirectional construction enables symmetrical clamping across both polarities without polarity marking - critical for AC-coupled or floating signal lines where voltage reversal occurs.
The device operates over -55 °C to +175 °C junction temperature range and sustains 400 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle. Thermal design is supported by RθJL = 66 °C/W and RθJA = 100 °C/W (lead length = 10 mm), enabling reliable operation in compact PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 214 V - maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 237–263 V at 1 mA - precise conduction onset ensures predictable clamping initiation during transients |
| VC (Clamping Voltage) | ≤344 V at IPPM = 1.2 A - limits downstream voltage stress to safe levels for 200–250 V-rated ICs and MOSFETs |
| PPPM (Peak Pulse Power) | 400 W (10/1000 μs) - withstands common lightning-induced surges per IEC 61000-4-5 Level 3 (1 kV/2 Ω) |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - negligible standby power loss and no interference with high-impedance sensing circuits |
| TJ max. | +175 °C - supports under-hood automotive environments and industrial enclosures with elevated ambient temperatures |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250CA | DO-214AA package; 250 V VWM; 400 W PPPM; lower RθJA (50 °C/W); higher capacitance (~150 pF) | Better thermal performance but larger footprint; higher junction capacitance may affect >10 MHz signal lines | Select SMBJ250CA when board space allows and lower thermal resistance is prioritized over high-frequency signal integrity |
| 1.5KE250CA | DO-201AD package; same VWM/VBR/VC specs; 1500 W PPPM (10/1000 μs); higher IFSM (200 A) | Higher surge capacity suits mains-connected equipment; larger package requires revised layout and assembly tooling | Choose 1.5KE250CA for heavy-duty industrial AC inputs where 1500 W surge rating is mandatory and DO-41 size is insufficient |
Compared with P4KE250CA-E3/54, SMBJ250CA offers superior thermal dissipation in a surface-mount format but increases board area and parasitic capacitance, whereas 1.5KE250CA delivers triple the surge power in a through-hole package requiring mechanical redesign - making P4KE250CA-E3/54 optimal for cost-sensitive, space-constrained automotive and consumer designs needing AEC-Q101 validation.

FAQ
What is the clamping voltage of P4KE250CA-E3/54 at its rated peak pulse current?
The P4KE250CA-E3/54 clamps to a maximum of 344 V when subjected to its specified peak pulse current of 1.2 A (10/1000 μs waveform). This VC value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring compatibility with 250 V-rated downstream components like MOSFETs and bridge rectifiers.
Is P4KE250CA-E3/54 suitable for automotive applications?
Yes, P4KE250CA-E3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its -55 °C to +175 °C operating junction temperature range, glass-passivated junction stability, and validation across temperature cycling, HTRB, and ESD tests make it appropriate for engine control modules, body electronics, and ADAS sensor interfaces where transient robustness and long-term reliability are mandatory.
How does the bidirectional configuration of P4KE250CA-E3/54 affect its PCB layout?
The P4KE250CA-E3/54 has no polarity marking and identical electrical behavior in both directions, simplifying PCB layout for AC-coupled or floating signal paths. Unlike unidirectional TVS diodes, it eliminates orientation verification during placement and supports symmetric protection schemes - such as differential line clamping - without requiring matched component pairs or directional routing constraints.
What is the thermal resistance from junction to lead (RθJL) for P4KE250CA-E3/54?
The P4KE250CA-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, measured with standard DO-41 lead geometry. This parameter enables accurate thermal modeling when the device is mounted with short leads to a copper pour or chassis ground, supporting reliable operation at full 400 W pulse rating without external heatsinking in most industrial and automotive implementations.
Does P4KE250CA-E3/54 meet RoHS and REACH compliance requirements?
Yes, P4KE250CA-E3/54 carries the "E3" suffix indicating full RoHS compliance per EU Directive 2011/65/EU and adherence to Vishay's material categorization standard (document #99912). It contains no restricted substances above threshold limits and is certified for use in environmentally regulated markets including the EU, China, and South Korea - with full traceability documentation available upon request.
