Product details
Overview
P6KE180CA-E3/54 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 P6KE180CA-E3/54 datasheet, P6KE180CA-E3/54 pinout, P6KE180CA-E3/54 application, or P6KE180CA-E3/54 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, AEC-Q101 qualification status, thermal resistance (RθJL = 20 °C/W), and compliance with UL 497B surge protector classification.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, limiting downstream voltage to ≤246 V at 2.4 A. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns).
Designed for unidirectional and bidirectional configurations, P6KE180CA-E3/54 supports both polarities without marking - unlike unidirectional variants that use cathode banding. It is rated for repetitive 0.01% duty cycle surges and derates linearly above 25 °C ambient per Fig. 2, with maximum junction temperature of +175 °C and thermal resistance junction-to-lead of 20 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1 mA test current - defines reliable turn-on threshold across production lot |
| VWM | 154 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| VC @ IPPM | 246 V at 2.4 A (10/1000 μs) - limits protected circuit voltage during worst-case surge |
| PPPM | 600 W - peak transient energy absorption capacity without failure |
| RθJL | 20 °C/W - enables thermal design using lead temperature (TL) instead of ambient for power derating |
| TJ max | +175 °C - allows operation in under-hood automotive environments and industrial enclosures |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |

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 VBR/VC specs | Better suited for surface-mount boards with limited airflow; requires rework of footprint and stencil | Select SMBJ180CA when board space is constrained and SMT assembly is preferred over through-hole. |
| 1.5KE180CA | Higher PPPM (1500 W); larger DO-201 package; identical VBR/VC and DO-15-compatible lead form | Used where higher single-pulse energy handling is required (e.g., generator excitation circuits) | Choose 1.5KE180CA only if system-level testing confirms need for >600 W surge margin; otherwise P6KE180CA-E3/54 offers optimal cost/size balance. |

FAQ
What is the clamping voltage of P6KE180CA-E3/54 at its rated peak pulse current?
The P6KE180CA-E3/54 has a maximum clamping voltage (VC) of 246 V when subjected to its rated peak pulse current of 2.4 A with a 10/1000 μs waveform. This value is measured per Fig. 1 in the Vishay datasheet 88369 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE180CA-E3/54 maintains this clamping performance across its qualified temperature range.
Is P6KE180CA-E3/54 suitable for automotive applications?
Yes, P6KE180CA-E3/54 is AEC-Q101 qualified per the Vishay datasheet revision 27-Sep-2021, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power rails. Its 175 °C maximum junction temperature, glass-passivated junction, and UL 497B recognition support deployment in under-hood and cabin environments. The P6KE180CA-E3/54 meets automotive reliability stress tests including temperature cycling and high-temperature reverse bias.
How does the bidirectional configuration of P6KE180CA-E3/54 affect PCB layout?
The bidirectional configuration of P6KE180CA-E3/54 eliminates polarity constraints during placement - both terminals are functionally identical, so no cathode band or orientation marking is present. This simplifies PCB layout, reduces assembly errors, and allows reuse of the same footprint for AC-coupled or floating signal lines. Unlike unidirectional variants, the P6KE180CA-E3/54 can be installed in either direction without affecting clamping behavior or electrical performance.
What is the standoff voltage rating for P6KE180CA-E3/54, and why does it matter?
The standoff voltage (VWM) of P6KE180CA-E3/54 is 154 V - the maximum continuous DC or RMS voltage the device can block without exceeding 1 μA leakage current. This rating ensures the P6KE180CA-E3/54 remains non-conductive during normal operation while providing headroom below VBR (171–189 V) to avoid false triggering. Selecting VWM ≥1.1× system operating voltage is critical to prevent premature conduction and power loss.
Does P6KE180CA-E3/54 meet any safety certifications?
Yes, P6KE180CA-E3/54 carries Underwriters Laboratories (UL) recognition under file E136766 for both unidirectional and bidirectional devices, compliant with UL 497B for telecommunications primary protectors. It also meets RoHS Directive 2011/65/EU (E3 suffix) and is rated for flammability UL 94 V-0 per molding compound specification. These certifications validate its use in safety-critical telecom, industrial, and automotive end equipment without requiring additional system-level testing.
