Product details
Overview
P6KE180CAHE3/54 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 180 V breakdown voltage (VBR min/max = 171 V / 189 V), 154 V standoff voltage (VWM), 246 V maximum clamping voltage at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6KE180CAHE3/54 datasheet, P6KE180CAHE3/54 pinout, P6KE180CAHE3/54 application, or P6KE180CAHE3/54 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, DO-15 mechanical compatibility, and thermal resistance (RθJL = 20 °C/W) for board-level surge protection design.
Technical Context
This device operates as a voltage-clamped shunt protector: when transient voltage exceeds VWM (154 V), it avalanches into low-impedance conduction to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), critical for suppressing ESD and inductive switching spikes.
Rated for 175 °C maximum junction temperature and qualified to AEC-Q101, the P6KE180CAHE3/54 supports automotive-grade reliability without polarity marking (bidirectional symmetry), and exhibits 0.108 %/°C temperature coefficient of VBR, enabling predictable clamping behavior across operating temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 154 V - maximum continuous reverse working voltage before avalanche conduction begins |
| VBR (Breakdown Voltage) | 171 V min / 189 V max at 1 mA - defines the voltage threshold at which TVS enters controlled avalanche |
| VC (Clamping Voltage) | 246 V at IPPM = 2.4 A - peak voltage seen by protected circuit during 10/1000 μs surge event |
| PPPM (Peak Pulse Power) | 600 W - maximum non-repetitive surge energy handling capability under standardized waveform |
| IPPM (Peak Pulse Current) | 2.4 A - peak current the device can safely shunt while maintaining VC ≤ 246 V |
| RθJL (Junction-to-Lead Thermal Resistance) | 20 °C/W - enables effective heat transfer to PCB copper or heatsink under sustained surge conditions |
| TJ max | 175 °C - maximum allowable junction temperature, supporting operation in under-hood automotive environments |
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 | DO-214AA package, lower RθJA (50 °C/W vs. 75 °C/W), same VWM/VC specs but 600 W rating at smaller footprint | Better suited for space-constrained PCBs where leaded DO-15 mounting is impractical | Select SMBJ180CA when board real estate is limited and surface-mount assembly is preferred |
| 1.5KE180CA | Higher 1500 W peak power rating, larger DO-201AD package, identical VBR/VWM/VC values but higher IPPM (5.2 A) | Used in higher-energy surge environments such as AC mains input stages or industrial motor drives | Choose 1.5KE180CA when system-level surge testing requires >600 W margin or higher IPPM headroom |
Compared with SMBJ180CA and 1.5KE180CA, the P6KE180CAHE3/54 offers optimal balance of AEC-Q101 qualification, DO-15 through-hole manufacturability, and 600 W surge capacity - making it ideal for cost-sensitive, high-volume automotive and industrial power rail protection where leaded reliability and thermal performance are prioritized over miniaturization or ultra-high energy handling.

FAQ
What does the "CA" suffix indicate in P6KE180CAHE3/54?
The "CA" suffix in P6KE180CAHE3/54 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6KE180A), it has no polarity marking and clamps equally in either direction, making it suitable for AC-coupled or differential signal lines where voltage polarity is not fixed.
Is P6KE180CAHE3/54 qualified for automotive use?
Yes, P6KE180CAHE3/54 is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88369, Revision 27-Sep-2021). The "HE3" suffix specifically indicates AEC-Q101 qualification and JESD 201 Class 2 whisker resistance - meeting reliability requirements for under-hood and chassis-mounted automotive electronics subject to thermal cycling and vibration.
What is the maximum clamping voltage of P6KE180CAHE3/54 under surge conditions?
The maximum clamping voltage (VC) of P6KE180CAHE3/54 is 246 V, measured at its rated peak pulse current (IPPM) of 2.4 A using the standard 10/1000 μs waveform. This value represents the highest voltage that will appear across protected circuitry during a defined surge event, ensuring downstream components remain within safe operating limits.
How does the DO-15 package of P6KE180CAHE3/54 affect thermal performance?
The DO-15 (DO-204AC) package of P6KE180CAHE3/54 delivers a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer to PCB copper pours or external heatsinks. While its junction-to-ambient resistance (RθJA) is 75 °C/W, proper pad design and copper area significantly improve sustained power dissipation - critical for repeated surge events in industrial power supplies.
Can P6KE180CAHE3/54 replace P6KE180A in a design?
No - P6KE180CAHE3/54 cannot directly replace unidirectional P6KE180A because they differ fundamentally in polarity behavior: P6KE180A clamps only in reverse bias and conducts forward current like a rectifier, whereas P6KE180CAHE3/54 clamps symmetrically in both directions. Substitution requires verifying circuit topology, especially whether forward conduction paths or DC bias conditions exist that would be disrupted by bidirectional operation.
