Product details
Overview
P6KE180-E3/73 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal lines. It features a 154 V standoff voltage (VWM), 171–189 V breakdown range (VBR) at 1 mA, 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - deployed in automotive power supply inputs and industrial sensor interfaces.
For engineers reviewing the P6KE180-E3/73 datasheet, P6KE180-E3/73 pinout, P6KE180-E3/73 application, or P6KE180-E3/73 equivalent, key selection criteria include clamping performance under 2.4 A surge, thermal resistance (RθJL = 20 °C/W), DO-15 package compatibility, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when transient voltage exceeds VBR, 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 protecting MOSFET gates and microcontroller I/O pins against ESD and inductive switching spikes.
Rated for 175 °C maximum junction temperature and 100 A non-repetitive forward surge (IFSM), the device sustains repetitive transients at ≤0.01% duty cycle. Clamping voltage is specified at 246 V for 2.4 A (10/1000 µs), with temperature coefficient of +0.108 %/°C - enabling accurate derating across automotive ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 154 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC rail margin for 13.5–16 V automotive systems. |
| VBR @ IT=1 mA | 171–189 V - guaranteed avalanche onset range; ensures consistent turn-on behavior across production lots and temperature. |
| VC @ IPPM=2.4 A | 246 V - maximum clamped voltage during 10/1000 µs surge; determines protected IC's voltage stress ceiling. |
| PPPM | 600 W - peak pulse power handling capability; supports robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct PCB copper pour heatsinking without external heatsink. |
| IFSM | 100 A - 8.3 ms half-sine surge rating; withstands motor commutation spikes and load dump events in vehicle ECUs. |
| TJ max | 175 °C - maximum junction temperature; supports operation in under-hood environments with minimal derating. |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, epoxy-molded case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. Cathode indicated by color band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes shunt path during avalanche conduction. |
| Cathode | High-side transient sensing terminal | Connected to protected line (e.g., battery rail); senses overvoltage and initiates clamping action. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170A | DO-214AA package; 170 V VWM; 274 V VC @ 2.2 A; same 600 W rating but higher clamping voltage. | Suitable for PCBs with surface-mount layout constraints; lower profile but requires reflow-compatible footprint. | Select when board space is limited and thermal coupling to copper pour is less effective than axial lead conduction. |
| 1.5KE180A | Same DO-15 package; identical VWM/VBR/VC specs; rated for 1.5 kW peak power (10/1000 µs) - larger die size. | Used where higher single-event surge margin is required, e.g., heavy-duty industrial motor drives with frequent commutation spikes. | Choose only if system-level testing confirms need for >600 W margin; otherwise P6KE180-E3/73 offers optimal cost-performance balance. |
Compared with SMBJ170A and 1.5KE180A, P6KE180-E3/73 delivers the lowest clamping voltage (246 V) in its class while maintaining AEC-Q101 qualification and RoHS compliance - making it the preferred choice for space-constrained automotive and industrial DC rail protection where precise voltage limiting is critical.

FAQ
What is the maximum clamping voltage of the P6KE180-E3/73 under standard test conditions?
The P6KE180-E3/73 has a maximum clamping voltage (VC) of 246 V when subjected to a 10/1000 µs waveform with a peak pulse current (IPPM) of 2.4 A. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. The P6KE180-E3/73 maintains this clamping performance across its qualified operating temperature range, supporting reliable design margining in harsh environments.
Is the P6KE180-E3/73 suitable for automotive applications?
Yes, the P6KE180-E3/73 is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its 175 °C maximum junction temperature, glass-passivated junction, and robust surge ratings align with ISO 7637-2 and ISO 16750-2 requirements. The P6KE180-E3/73 meets these standards without derating in typical under-hood ambient conditions up to 125 °C.
What does the "E3/73" suffix indicate in P6KE180-E3/73?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 1A whisker resistance. The "/73" indicates packaging in 73 mm tape-and-reel format per Vishay's ordering convention. The P6KE180-E3/73 is not AEC-Q101 qualified - that designation applies only to HE3-suffixed variants. This distinction is critical when selecting for automotive versus industrial applications.
How does the P6KE180-E3/73 compare to bi-directional TVS diodes like P6KE180CA?
The P6KE180-E3/73 is unidirectional and protects only against positive transients on the cathode side relative to anode (ground). In contrast, P6KE180CA provides symmetrical clamping for AC-coupled or floating signal lines. The P6KE180-E3/73 offers lower leakage (<1 µA at 154 V) and tighter VBR tolerance than its bi-directional counterpart, making it preferable for DC power rail protection where polarity is fixed and leakage sensitivity is high.
What thermal considerations apply when mounting the P6KE180-E3/73 on a PCB?
The P6KE180-E3/73 has a junction-to-lead thermal resistance (RθJL) of 20 °C/W, meaning effective heat dissipation relies on adequate copper area connected to its axial leads. For continuous 5.0 W power dissipation, minimum 100 mm² of 2 oz copper per lead is recommended. The P6KE180-E3/73 must be mounted with ≥0.230 inch (5.8 mm) lead length to meet thermal derating curves - shorter leads increase RθJA and reduce safe operating area.
