Product details
Overview
P4KE250C-E3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-41 package, rated for 400 W peak pulse power (10/1000 μs), 214 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR at 1 mA), and clamps to ≤344 V at 1.2 A peak pulse current. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the P4KE250C-E3/54 datasheet, P4KE250C-E3/54 pinout, P4KE250C-E3/54 application, or P4KE250C-E3/54 equivalent, key selection criteria include clamping voltage margin vs. protected device VDS(max), thermal resistance (RθJL = 66 °C/W), unidirectional polarity marking, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to limit transient overvoltage before damage occurs. Its unidirectional configuration uses a cathode band for polarity identification and exhibits VF = 5.0 V at 25 A forward surge.
Designed for single-pulse suppression under IEC 61000-4-5 Level 4 conditions, it supports repetitive duty cycles up to 0.01 % and derates linearly above TA = 25 °C per Fig. 2, with maximum junction temperature of +175 °C and thermal resistance junction-to-lead of 66 °C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250A | DO-214AA package, 600 W PPPM, lower RθJA (50 °C/W), same VWM/VBR range | Better thermal performance in surface-mount layouts; requires rework of footprint and stencil | Select when board space allows SMD placement and higher surge margin is required |
| 1.5KE250A | Same DO-41 package, 1500 W PPPM, higher VC (357 V), larger junction capacitance | Higher energy handling but slower response due to larger die; not AEC-Q101 qualified | Choose for non-automotive industrial systems needing >1 kW surge capacity |
Compared with SMBJ250A and 1.5KE250A, P4KE250C-E3/54 offers optimal balance of axial-leaded manufacturability, AEC-Q101 qualification, and 400 W surge rating-making it preferred for cost-sensitive automotive and industrial through-hole designs where footprint reuse and qualification traceability are mandatory.

FAQ
What is the clamping voltage of P4KE250C-E3/54 at its rated peak pulse current?
The P4KE250C-E3/54 clamps to a maximum of 344 V at its specified peak pulse current of 1.2 A under 10/1000 μs waveform conditions. This value is measured per Figure 1 in the Vishay datasheet 88365 and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping voltage directly determines whether downstream components like MOSFETs or regulators remain within safe operating area.
Is P4KE250C-E3/54 RoHS-compliant and lead-free?
Yes, P4KE250C-E3/54 is RoHS-compliant and lead-free, indicated by the "E3" suffix per Vishay's ordering nomenclature. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device complies with JEDEC JESD201 Class 1A whisker testing. Full compliance documentation is available in Vishay's material declaration portal.
Does P4KE250C-E3/54 have AEC-Q101 qualification?
No-P4KE250C-E3/54 is not AEC-Q101 qualified. Only variants with "HE3" suffix (e.g., P4KE250AHE3/54) carry AEC-Q101 qualification. The "E3" suffix denotes commercial-grade RoHS compliance only. For automotive applications requiring qualification, engineers must specify the HE3 version and verify availability through Aetrix Electronics' automotive component program.
What is the thermal resistance junction-to-lead (RθJL) for P4KE250C-E3/54?
The thermal resistance junction-to-lead (RθJL) for P4KE250C-E3/54 is 66 °C/W, as specified in the Thermal Characteristics table of Vishay document 88365. This parameter enables accurate calculation of junction temperature rise during surge events and informs PCB copper pour design or heatsink integration for applications with repeated transient exposure.
How does the unidirectional configuration of P4KE250C-E3/54 affect its circuit placement?
The unidirectional configuration of P4KE250C-E3/54 requires correct orientation: the cathode (marked with a band) connects to the line being protected (e.g., 24 V rail), and the anode connects to ground or reference. Reversal prevents clamping during positive transients and risks catastrophic failure. This polarity dependency makes it unsuitable for bidirectional signal lines unless paired with a second device or replaced with a CA-suffixed variant.
