Product details
Overview
P4KE180CA-E3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 154 V standoff voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA, 400 W peak pulse power (10/1000 μs), clamping voltage of 246 V at 1.6 A peak pulse current, and operates from –55 °C to +175 °C.
For engineers reviewing the P4KE180CA-E3/54 datasheet, P4KE180CA-E3/54 pinout, P4KE180CA-E3/54 application, or P4KE180CA-E3/54 equivalent, this device is selected for robust overvoltage protection in automotive sensor signal lines, industrial I/O interfaces, telecom power rails, and MOSFET gate drive circuits where bidirectional clamping and AEC-Q101 qualification are required.
Technical Context
The P4KE180CA-E3/54 implements a glass-passivated PN junction optimized for fast transient response (<1 ns) and low incremental surge resistance. Its bidirectional structure enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
It delivers 400 W peak pulse power under standardized 10/1000 μs waveform with 0.01% duty cycle, and maintains stable clamping performance across –55 °C to +175 °C junction temperature range. Thermal resistance is 66 °C/W (junction-to-lead) and 100 °C/W (junction-to-ambient, LLead = 10 mm).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (min/max) | 171 V / 189 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during transients. |
| VC @ IPPM | 246 V at 1.6 A - Clamped voltage during 10/1000 μs surge; determines maximum stress on downstream circuitry. |
| PPPM | 400 W - Peak pulse power handling capability; supports high-energy ESD and lightning surge immunity per IEC 61000-4-5. |
| IPPM | 1.6 A - Peak pulse current corresponding to VC; used to size series impedance and verify system-level surge margin. |
| TJ max. | +175 °C - Maximum junction temperature; enables operation in under-hood automotive and high-temperature industrial environments. |
| RθJL | 66 °C/W - Junction-to-lead thermal resistance; informs heatsinking requirements when mounted on PCB copper pour. |

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 154 V VWM, but lower 600 W PPPM and higher 274 V VC at 2.2 A. | Preferred for space-constrained PCBs; not suitable for through-hole legacy designs or high-temperature lead-soldered assemblies. | Select SMBJ180CA when board real estate is limited and reflow soldering is available; verify thermal pad layout for 600 W derating. |
| 1.5KE180CA | Higher 1500 W PPPM, same DO-41 package, but larger 2.5 mm lead diameter and 2.0 A IPPM; VC = 259 V. | Used where higher surge energy (e.g., IEC 61000-4-5 Level 5) must be absorbed without replacement of series impedance. | Choose 1.5KE180CA when system-level surge testing exceeds 400 W requirements; confirm mechanical fit with existing DO-41 footprint. |
Compared with SMBJ180CA and 1.5KE180CA, the P4KE180CA-E3/54 offers balanced surge capability (400 W), proven AEC-Q101 qualification, and cost-effective through-hole assembly-making it optimal for automotive and industrial applications requiring verified reliability without over-engineering.

FAQ
What is the standoff voltage (VWM) of the P4KE180CA-E3/54?
The P4KE180CA-E3/54 has a maximum working standoff voltage (VWM) of 154 V. This value represents the highest continuous reverse voltage the device can withstand without entering avalanche conduction. It is derived from the minimum breakdown voltage (171 V) with a safety margin, ensuring reliable operation in 130–150 V nominal systems such as 48 V telecom or 120 VAC-derived rails.
Is the P4KE180CA-E3/54 suitable for automotive applications?
Yes, the P4KE180CA-E3/54 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C, making it suitable for under-hood and powertrain applications. Its bidirectional clamping, glass-passivated junction, and DO-41 package with matte tin leads meet automotive reliability requirements for sensor protection, ECU power inputs, and communication line hardening.
How does the clamping voltage (VC) of P4KE180CA-E3/54 compare to its breakdown voltage?
The P4KE180CA-E3/54 has a breakdown voltage (VBR) range of 171–189 V at 1 mA and a clamping voltage (VC) of 246 V at 1.6 A peak pulse current. The ~36 % overvoltage margin between VBR min and VC reflects the device's incremental resistance during surge conduction-critical for determining whether downstream components remain within absolute maximum ratings during transient events.
What is the package type and lead finish of P4KE180CA-E3/54?
The P4KE180CA-E3/54 uses the DO-41 (DO-204AL) axial-leaded package with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. The "E3" suffix indicates RoHS-compliant commercial-grade construction meeting JESD 201 Class 1A whisker resistance, and the "54" denotes 13-inch paper tape and reel packaging (5500 units per reel).
Can P4KE180CA-E3/54 be used in bidirectional AC signal paths?
Yes, the P4KE180CA-E3/54 is explicitly designed for bidirectional applications-the "CA" suffix denotes symmetrical clamping characteristics in both polarities. It exhibits identical VBR, VC, and leakage performance regardless of voltage polarity, making it ideal for protecting AC-coupled data lines, transformer-isolated interfaces, and floating sensor outputs without polarity concerns.
