Product details
Overview
P6KE180HE3/73 from Vishay General Semiconductor is a uni-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (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 V / 189 V), 154 V stand-off 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 - used to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD in automotive and industrial control systems.
For engineers reviewing the P6KE180HE3/73 datasheet, P6KE180HE3/73 pinout, P6KE180HE3/73 application, or P6KE180HE3/73 equivalent, this AEC-Q101 qualified TVS offers verified surge immunity, low clamping ratio (VC/VWM ≈ 1.60), RoHS-compliant matte tin-plated leads, and thermal resistance (RθJL = 20 °C/W) critical for sustained transient suppression in space-constrained PCB layouts.
Technical Context
This device operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ at VWM = 154 V), 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 avalanche characteristics and fast response time (<1 ns).
Designed for single-polarity DC circuits, P6KE180HE3/73 uses cathode-band polarity marking and supports repetitive surge duty cycles up to 0.01 %, with derating above 25 °C per Fig. 2 and maximum junction temperature of 175 °C. It complies with UL 497B (QVGQ2 recognition) and meets JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 171 V / 189 V at 1.0 mA test current - defines precise avalanche initiation threshold for reliable triggering |
| VWM | 154 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 246 V at 2.4 A (10/1000 μs) - clamping voltage that determines protected circuit's worst-case overvoltage stress |
| PPPM | 600 W - peak transient energy handling capacity without failure under standardized surge waveform |
| IFSM | 100 A (8.3 ms half-sine) - surge current rating defining robustness against repetitive inductive kick events |
| TJ max | 175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 20 °C/W - thermal resistance from junction to lead, critical for estimating temperature rise during surge dissipation |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded molded epoxy case with UL 94 V-0 flammability rating; matte tin-plated leads solderable per J-STD-002/JESD 22-B102; cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or return path; completes shunt path during transient conduction |
| Cathode | High-side connection point | Connected to protected line; avalanche conduction initiates from cathode to anode when VAK > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per stress test plan |
| Glass passivated junction | Ensures stable, repeatable avalanche characteristics across lifetime and temperature with minimal parameter drift |
| 600 W peak pulse power (10/1000 μs) | Enables protection against severe transients such as ISO 7637-2 Pulse 1/2a/5a in 12 V vehicle systems |
| Clamping ratio VC/VWM = 1.60 | Minimizes overvoltage margin required on protected ICs, reducing need for oversized voltage ratings |
| RoHS-compliant + JESD 201 Class 2 whisker resistance | Supports long-term reliability in high-humidity, high-temperature PCB assemblies without tin whisker risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ180A | Same VBR range (171–189 V), but SMC (DO-214AB) package - 50 % smaller footprint, higher IPPM (3.2 A), lower RθJA | Better suited for high-density layouts; requires rework of pad geometry and thermal relief design | Select SMBJ180A when board space is constrained and thermal management via copper pour is feasible |
| 1.5KE180A | Same electrical specs but higher power rating (1500 W), larger DO-201AD package, and higher VF (5.0 V) | Used where higher single-event surge margin is required, e.g., outdoor telecom cabinets exposed to lightning-induced surges | Choose 1.5KE180A only if system-level testing confirms need for >600 W capability and mechanical envelope allows larger body |
Compared with SMBJ180A and 1.5KE180A, P6KE180HE3/73 delivers AEC-Q101 validation and DO-15 through-hole compatibility ideal for legacy automotive harness interfaces and manual assembly processes, while maintaining identical clamping performance at lower cost and proven field reliability.

FAQ
What is the clamping voltage of P6KE180HE3/73 and how is it measured?
The clamping voltage (VC) of P6KE180HE3/73 is 246 V, measured at a peak pulse current (IPPM) of 2.4 A using the standardized 10/1000 μs double-exponential waveform per IEC 61000-4-5. This value represents the maximum voltage imposed on the protected circuit during surge conduction and is guaranteed across the full operating temperature range (−55 °C to +175 °C). The P6KE180HE3/73 achieves this clamping performance due to its low incremental surge resistance and optimized avalanche junction design.
Is P6KE180HE3/73 suitable for automotive applications?
Yes, P6KE180HE3/73 is AEC-Q101 qualified and specifically rated for automotive use, including under-hood environments. Its 175 °C maximum junction temperature, JESD 201 Class 2 whisker resistance, and compliance with UL 497B (QVGQ2 recognition) confirm suitability for engine control units, body electronics, and ADAS power supplies. The "HE3" suffix denotes AEC-Q101 qualification and RoHS compliance - making P6KE180HE3/73 appropriate for Tier 1 automotive BOMs where process and reliability validation are mandatory.
How does the VWM of 154 V relate to system voltage selection for P6KE180HE3/73?
The 154 V stand-off voltage (VWM) of P6KE180HE3/73 must exceed the maximum continuous DC operating voltage of the protected circuit by at least 10–15 % to avoid leakage-induced power loss or thermal runaway. For example, it is correctly applied on 120 V DC bus systems (e.g., telecom rectifier outputs or industrial 24/48 V systems with ripple), where nominal voltage plus tolerance remains below 154 V. Using P6KE180HE3/73 on a 160 V nominal rail would risk premature conduction and accelerated degradation.
What is the meaning of the "HE3" suffix in P6KE180HE3/73?
The "HE3" suffix in P6KE180HE3/73 indicates two key attributes: RoHS compliance (per Directive 2011/65/EU) and AEC-Q101 qualification. Unlike the "E3" suffix (RoHS-only, commercial grade), "HE3" devices undergo extended stress testing including temperature cycling, high-temperature reverse bias, and surge endurance - verifying suitability for automotive and mission-critical industrial applications. The "73" denotes packaging in 7-inch tape-and-reel (4000 pcs/reel), per Vishay's ordering convention.
Can P6KE180HE3/73 be used in bi-directional configurations?
No, P6KE180HE3/73 is a uni-directional TVS diode, identifiable by its cathode band marking and specified parameters (VBR, VWM, VC) for reverse-biased operation only. For bi-directional protection, Vishay offers the P6KE180CA variant - which has symmetric breakdown in both polarities and no polarity marking. Substituting P6KE180HE3/73 in a bi-directional circuit would result in forward conduction and potential failure during positive transients; always verify polarity designation before placement. The P6KE180HE3/73 must be oriented with cathode toward the protected line.
