Product details
Overview
P4KE180C-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for clamping voltage transients on signal or power lines. It features 180 V breakdown voltage (VBR min/max = 171–189 V), 154 V standoff voltage (VWM), 246 V clamping voltage at 1.6 A peak pulse current (VC), 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the P4KE180C-E3/54 datasheet, P4KE180C-E3/54 pinout, P4KE180C-E3/54 application, or P4KE180C-E3/54 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, bidirectional clamping behavior, automotive-grade reliability data, and direct alternatives with documented parameter divergence.
Technical Context
The P4KE180C-E3/54 operates as a silicon avalanche diode with glass-passivated junction, enabling symmetric clamping in both polarities. Its bidirectional architecture eliminates polarity marking and supports AC-coupled or floating-line protection without orientation constraints.
It delivers 400 W transient suppression under standardized 10/1000 µs waveform at ≤0.01% duty cycle, with thermal resistance of 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient). Maximum junction temperature is rated at +175 °C, and it meets JESD 201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V - ensures reliable avalanche conduction onset across manufacturing lot and temperature range |
| VWM | 154 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 246 V at 1.6 A - clamped voltage during 10/1000 µs surge, defining protected circuit's max overvoltage exposure |
| PPPM | 400 W - peak transient energy absorption capability under standard waveform, derated above 25 °C |
| IFSM | Not applicable - bidirectional device has no forward surge rating; only unidirectional variants specify 40 A 8.3 ms half-sine |
| TJ max. | +175 °C - enables operation in under-hood automotive environments and industrial enclosures |
| Package | DO-41 (DO-204AL) - axial-leaded through-hole package with UL 94 V-0 molded epoxy body |
Pinout & Package
DO-41 (DO-204AL) package: axial-leaded, cylindrical epoxy body, 2.0–2.7 mm diameter, 5.2 mm body length, 9.5 mm lead length minimum. No polarity marking - symmetrical bidirectional construction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180CA | Surface-mount SMB package; same VWM (154 V), lower VC (260 V), higher IPPM (1.53 A), 600 W rating | Requires PCB rework for SMT layout; better suited for space-constrained designs with automated assembly | Select when board real estate is limited and reflow compatibility is required; not drop-in for through-hole DO-41 footprint |
| 1.5KE180CA | Higher peak power (1500 W), larger DO-201AE package, same VBR/VWM, VC = 259 V at 5.8 A | Used where higher single-event surge margin is needed (e.g., outdoor telecom cabinets) | Choose for enhanced robustness in harsh environments; requires larger PCB pad area and higher mounting torque |
Compared with P4KE180C-E3/54, SMBJ180CA offers superior power density but mandates SMT redesign, while 1.5KE180CA provides triple the pulse power in a larger through-hole package-both retain identical voltage ratings but differ in thermal handling, footprint, and surge endurance profile.

FAQ
What does the "C" suffix in P4KE180C-E3/54 indicate?
The "C" suffix in P4KE180C-E3/54 denotes a bidirectional configuration, meaning the device clamps voltage transients equally in both polarities without polarity marking. Unlike unidirectional variants (e.g., P4KE180A), the P4KE180C-E3/54 has no cathode band and is used where AC signals, floating lines, or polarity-agnostic protection is required - confirmed in Vishay document 88365, section "Devices for Bi-Direction Applications".
Is P4KE180C-E3/54 RoHS-compliant and lead-free?
Yes, P4KE180C-E3/54 is RoHS-compliant and lead-free. The "E3" suffix explicitly indicates commercial-grade, RoHS-compliant construction per Vishay's ordering nomenclature. Its matte tin-plated leads meet J-STD-002 solderability standards, and the device complies with JEDEC JESD201 Class 1A whisker testing - all verified in the "Ordering Information" and "Mechanical Data" sections of document 88365.
What is the maximum clamping voltage VC for P4KE180C-E3/54, and at what current is it specified?
The maximum clamping voltage VC for P4KE180C-E3/54 is 246 V, measured at a peak pulse current IPPM of 1.6 A under the standard 10/1000 µs waveform. This value is listed in the "Electrical Characteristics" table of Vishay document 88365 for the P4KE180A/C family and defines the upper voltage limit imposed on protected circuits during surge events.
Does P4KE180C-E3/54 have AEC-Q101 qualification?
No - P4KE180C-E3/54 is not AEC-Q101 qualified. Only variants with the "HE3" suffix (e.g., P4KE180CHE3/54) carry AEC-Q101 qualification, as stated in the "Mechanical Data" section: "Base P/N-E3 – RoHS-compliant, commercial grade; Base P/NHE3 – RoHS-compliant, AEC-Q101 qualified." The "E3" suffix confirms commercial-grade status only.
What is the standoff voltage VWM and leakage current specification for P4KE180C-E3/54?
The standoff voltage VWM for P4KE180C-E3/54 is 154 V, and the maximum reverse leakage current ID at this voltage is 1.0 µA at TA = 25 °C. This specification ensures minimal power loss and signal interference in standby or low-power modes, and is directly extracted from the "Electrical Characteristics" table in Vishay document 88365 for the P4KE180A/C entry.
