Product details
Overview
P6KE180AHE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for primary overvoltage protection of DC power rails and signal lines. It features 180 V breakdown voltage (VBR min/max = 171–189 V), 154 V standoff voltage (VWM), 246 V clamping voltage at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply input stages to protect downstream MOSFETs and microcontrollers from load dump transients.
For engineers reviewing the P6KE180AHE3/54 datasheet, P6KE180AHE3/54 pinout, P6KE180AHE3/54 application, or P6KE180AHE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 175 °C max junction temperature, low 0.108 %/°C VBR temperature coefficient, and compatibility with lead-free reflow and wave soldering per J-STD-002/JESD 22-B102.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at 154 V), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the DO-15 package provides mechanical robustness and thermal path via leads.
Designed for single-pulse and low-duty-cycle repetitive surges, P6KE180AHE3/54 sustains 600 W peak power only at TA = 25 °C and derates linearly above 25 °C (per Fig. 2), with maximum IFSM = 100 A (8.3 ms half-sine) and RθJL = 20 °C/W enabling effective heat dissipation through PCB copper traces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for safe DC rail operation. |
| VBR (min/max) | 171 V / 189 V at 1 mA - Confirmed breakdown range defining turn-on threshold; ensures reliable triggering above system nominal voltage. |
| VC @ IPPM | 246 V at 2.4 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on protected ICs. |
| PPPM | 600 W - Peak pulse power handling capability; defines survivability against standardized lightning/surge waveforms. |
| TJ max | +175 °C - Maximum junction temperature; enables use in under-hood automotive environments without thermal shutdown. |
| Package | DO-15 (DO-204AC) - Industry-standard axial-leaded package with 0.242–0.258 inch body length; compatible with automated insertion and wave soldering. |
| AEC-Q101 | Qualified - Certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |
Pinout & Package
DO-15 (DO-204AC) molded epoxy package with matte tin-plated leads. Cathode indicated by color band on one end; anode is unmarked. Leads are solderable per J-STD-002 and JESD 22-B102; rated for solder dip ≤275 °C for 10 s.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Provides low-VF path during forward conduction; must be routed to ground or return plane for proper TVS operation. |
| Cathode | Current exit terminal in forward bias; marked with color band; connected to higher-potential side (e.g., +12 V rail). | Defines polarity-sensitive clamping direction; reverse-biased during normal operation; conducts surge current to ground when VIN > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Ensures stable leakage current (<1 μA at VWM) and long-term reliability under thermal cycling and humidity exposure. |
| 600 W peak pulse power (10/1000 μs) | Withstands ISO 7637-2 Pulse 5a (load dump) transients up to 120 V peak for automotive 12 V systems without degradation. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including temperature cycling (-55 °C to +175 °C), HTRB, and ESD (HBM ≥8 kV). |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns response), reducing stress on protected MOSFET gate oxides. |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance; suitable for high-reliability industrial and automotive assembly processes. |
Applications
| Automotive Power Input Protection | Industrial PLC I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | DO-214AA package; same VWM/VBR/VC specs; 600 W rating; surface-mount instead of axial. | Requires SMT placement and reflow profile optimization; not suitable for through-hole legacy designs or high-vibration mechanical retention. | Select SMBJ180A when board space is constrained and automated SMT assembly is available. |
| 1.5KE180A | Same DO-15 package; identical electrical specs; lacks AEC-Q101 qualification; commercial-grade only. | Not approved for automotive production; acceptable for industrial prototypes or non-safety-critical consumer devices. | Choose 1.5KE180A for cost-sensitive applications where automotive qualification is unnecessary. |
Compared with SMBJ180A and 1.5KE180A, P6KE180AHE3/54 uniquely combines AEC-Q101 qualification, axial DO-15 form factor, and verified 175 °C operation - making it the only option qualified for under-hood automotive power rail protection without layout redesign.

FAQ
What is the maximum clamping voltage of P6KE180AHE3/54 under surge conditions?
The P6KE180AHE3/54 has a maximum clamping voltage (VC) of 246 V at 2.4 A peak pulse current (IPPM) with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance remains stable across its full operating temperature range of -55 °C to +175 °C, as confirmed in Vishay's characterization curves.
Is P6KE180AHE3/54 suitable for automotive under-hood applications?
Yes, P6KE180AHE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +175 °C, making it suitable for under-hood automotive applications such as engine control units and body control modules. Its DO-15 package withstands mechanical vibration, and the HE3 suffix confirms compliance with JESD 201 Class 2 whisker resistance - critical for long-term reliability in harsh environments.
How does the P6KE180AHE3/54 differ from the commercial-grade P6KE180A-E3/54?
The P6KE180AHE3/54 differs from P6KE180A-E3/54 solely in qualification level: the "H" prefix denotes AEC-Q101 qualification, while the base P6KE180A-E3/54 is commercial grade only. Both share identical electrical specifications (VWM = 154 V, VBR = 171–189 V, VC = 246 V), DO-15 packaging, and RoHS compliance. No parametric or physical differences exist beyond test validation scope.
What is the standoff voltage rating for P6KE180AHE3/54?
The standoff voltage (VWM) for P6KE180AHE3/54 is 154 V - the maximum DC or continuous reverse voltage that can be applied without exceeding 1 μA leakage current. This rating ensures reliable blocking behavior during normal 12 V or 24 V system operation while maintaining sufficient margin below the 171 V minimum breakdown voltage to prevent false triggering.
Can P6KE180AHE3/54 be used in bidirectional configurations?
No, P6KE180AHE3/54 is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., P6KE180CA). Using P6KE180AHE3/54 in bidirectional AC applications would result in forward conduction during negative half-cycles, causing failure. For bidirectional protection, select the CA-series part with matched VBR and VC ratings.
