Product details
Overview
P4KE180C-E3/73 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 a 154 V standoff voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA test current, 400 W peak pulse power (10/1000 μs), and clamps to ≤246 V at 1.6 A peak pulse current. It is used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P4KE180C-E3/73 datasheet, P4KE180C-E3/73 pinout, P4KE180C-E3/73 application, or P4KE180C-E3/73 equivalent, this page delivers verified electrical parameters, DO-41 terminal mapping, AEC-Q101 qualification status, bidirectional clamping behavior, and real-world use cases in automotive and industrial transient protection circuits.
Technical Context
The P4KE180C-E3/73 operates as a silicon avalanche diode with glass-passivated junction, enabling fast response (<1 ns) to ESD and lightning-induced transients. Its bidirectional symmetry ensures identical clamping in both polarities, eliminating polarity dependency in AC-coupled or floating lines.
It complies with AEC-Q101 for automotive-grade reliability and supports repetitive surge events at 0.01% duty cycle. Thermal resistance is 66 °C/W (junction-to-lead), and maximum junction temperature is 175 °C - enabling operation in under-hood environments without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 171–189 V at 1 mA - Avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | ≤246 V at IPPM = 1.6 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream ICs |
| PPPM (Peak Pulse Power) | 400 W - Sustained energy absorption capability for standardized 10/1000 μs waveform per IEC 61000-4-5 |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby power loss and signal integrity impact in high-impedance interfaces |
| TJ max | 175 °C - Enables deployment in engine control units, motor drives, and other high-temperature industrial zones |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics per stress-test requirements including HTOL, TC, and HAST |
Pinout & Package

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 (vs. axial DO-41); same 154 V VWM, 171–189 V VBR, but lower 600 W PPPM rating | Better suited for space-constrained PCBs; requires reflow-compatible layout and lacks through-hole mechanical retention | Select SMBJ180CA when board area is limited and automated SMT assembly is available; P4KE180C-E3/73 remains preferred for manual repair, high-vibration mounts, or legacy through-hole designs. |
| 1.5KE180CA | Higher 1500 W peak pulse power (10/1000 μs); same DO-41 package and bidirectional configuration; VWM = 154 V, VBR = 171–189 V | Targeted at higher-energy threat environments (e.g., industrial motor drives, utility metering) where 400 W is insufficient | Choose 1.5KE180CA when system-level surge testing exceeds IEC 61000-4-5 Level 3; P4KE180C-E3/73 is optimal for cost-sensitive, standard-compliance applications with moderate surge exposure. |
Compared with SMBJ180CA and 1.5KE180CA, the P4KE180C-E3/73 delivers balanced performance for mid-tier surge immunity: sufficient 400 W clamping for automotive and industrial I/O, proven AEC-Q101 reliability, and low-cost through-hole manufacturability - making it the default choice where footprint, qualification, and cost converge.

FAQ
What is the polarity configuration of P4KE180C-E3/73?
The "C" suffix in P4KE180C-E3/73 explicitly denotes bidirectional construction. Unlike unidirectional variants (e.g., P4KE180A), this device has no cathode marking and provides symmetrical clamping in both directions - essential for AC-coupled lines, differential buses, or floating grounds where polarity cannot be guaranteed.
Does P4KE180C-E3/73 meet automotive qualification standards?
Yes, P4KE180C-E3/73 is AEC-Q101 qualified, as confirmed in Vishay document 88365 (Rev. 16-Sep-2021). This certification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST), validating its use in engine control, body electronics, and ADAS modules.
What is the maximum clamping voltage of P4KE180C-E3/73 under surge conditions?
The maximum clamping voltage (VC) of P4KE180C-E3/73 is 246 V at a peak pulse current (IPPM) of 1.6 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the datasheet and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
How does the DO-41 package of P4KE180C-E3/73 affect thermal performance?
The DO-41 package delivers a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W, enabling effective heat conduction to PCB copper or chassis mounts. At 1.5 W steady-state dissipation (PD), this allows ~100 °C rise above lead temperature - supporting reliable operation in ambient temperatures up to 75 °C without forced cooling.
Is P4KE180C-E3/73 RoHS-compliant and lead-free?
Yes, the "E3" suffix confirms P4KE180C-E3/73 is RoHS-compliant and lead-free per EU Directive 2011/65/EU. The matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the molding compound satisfies UL 94 V-0 flammability requirements.
